Many African protected areas (PAs) are not functioning effectively. We reviewed the performance of Zambia's PA network and provide insights into how their effectiveness might be improved. Zambia's PAs are under-performing in ecological, economic and social terms. Reasons include: a) rapidly expanding human populations, poverty and open-access systems in Game Management Areas (GMAs) resulting in widespread bushmeat poaching and habitat encroachment; b) underfunding of the Zambia Wildlife Authority (ZAWA) resulting in inadequate law enforcement; c) reliance of ZAWA on extracting revenues from GMAs to cover operational costs which has prevented proper devolution of user-rights over wildlife to communities; d) on-going marginalization of communities from legal benefits from wildlife; e) under-development of the photo-tourism industry with the effect that earnings are limited to a fraction of the PA network; f) unfavourable terms and corruption which discourage good practice and adequate investment by hunting operators in GMAs; g) blurred responsibilities regarding anti-poaching in GMAs resulting in under-investment by all stakeholders. The combined effect of these challenges has been a major reduction in wildlife densities in most PAs and the loss of habitat in GMAs. Wildlife fares better in areas with investment from the private and/or NGO sector and where human settlement is absent. There is a need for: elevated government funding for ZAWA; greater international donor investment in protected area management; a shift in the role of ZAWA such that they focus primarily on national parks while facilitating the development of wildlife-based land uses by other stakeholders elsewhere; and new models for the functioning of GMAs based on joint-ventures between communities and the private and/or NGO sector. Such joint-ventures should provide defined communities with ownership of land, user-rights over wildlife and aim to attract long-term private/donor investment. These recommendations are relevant for many of the ...

The number and area of wildlife ranches in Zambia increased from 30 and 1,420 km2 in 1997 to 177 and ,6,000 km2 by 2012. Wild ungulate populations on wildlife ranches increased from 21,000 individuals in 1997 to ,91,000 in 2012, while those in state protected areas declined steeply. Wildlife ranching and crocodile farming have a turnover of ,USD15.7 million per annum, compared to USD16 million from the public game management areas which encompass an area 29 times larger. The wildlife ranching industry employs 1,200 people (excluding jobs created in support industries), with a further ,1,000 individuals employed through crocodile farming. Wildlife ranches generate significant quantities of meat (295,000 kg/annum), of which 30,000 kg of meat accrues to local communities and 36,000 kg to staff.

Macroecological analyses capture the widespread nature of wild mammal range contractions and population declines globally, with Neotropical rainforests particularly vulnerable. Yet there is a paucity of basic population biology data capturing local empirically observed population changes. We generated species-specific and aggregated temporal trends in populations of terrestrial mammals in Cusuco National Park, north-west Honduras testing the effects of body-size, hunting and zonal protection measures. Hunted species, regardless of body size, exhibited declines (ca. -7% per year) with greater rapidity of decline in the park's more accessible and less rigorously protected buffer zone. The site was once regarded as a remaining strong of Baird's tapir (Tapirus bairdii), IUCN Red Listed as Endangered, but our data suggest its near local extirpation from monitored sites. Hunted deer (Mazama temama and Odocoileus virginianus) and paca (Cuniculus paca) also declined substantially. Whilst species-specific trends varied among unhunted species (e.g. wild cats, mustelids etc.) they, nevertheless, also exhibited an aggregated decline throughout the park (ca. -6% per year). Such was the rapidity of these declines that we estimate substaintial mammalian defaunation of Cusuco National Park by the mid-2020s leaving a notionally highly protected area mostly devoid of terrestrial mammals and the associated ecosystem services they deliver (so-called 'empty forest syndrome'). We call on Governments and non-governmental organizations including conservation charities to prioritize urgent efforts to secure funding and personnel to ensure designated areas are adequately protected with enforcement of existing legislative protection whether through patrols or capacity building to efficiently curtail ongoing defaunation.

Primates occur in 90 countries, but four—Brazil, Madagascar, Indonesia, and the Democratic Republic of the Congo (DRC)—harbor 65% of the world's primate species (439) and 60% of these primates are Vulnerable, Endangered, or Critically Endangered (IUCN Red List of Threatened Species 2017-3). Considering their importance for global primate conservation, we examine the anthropogenic pressures each country is facing that place their primate populations at risk. Habitat loss and fragmentation are main threats to primates in Brazil, Madagascar and Indonesia. However, in DRC hunting for the commercial bushmeat trade is the primary threat. Encroachment on primate habitats driven by local and global market demands for food and non-food commodities hunting, illegal trade, the proliferation of invasive species, and human and domestic-animal borne infectious diseases cause habitat loss, population declines, and extirpation. Modeling agricultural expansion in the 21st century for the four countries under a worst-case-scenario, showed a primate range contraction of 78% for Brazil, 72% for Indonesia 62% for Madagascar and 32% for DRC. These pressures unfold in the context of expanding human populations with low levels of development. Weak governance across these four countries may limit effective primate conservation planning. We examine landscape and local approaches to effective primate conservation policies and assess the distribution of protected areas and primates in each country. P rimates in Brazil and Madagascar have 38% of their range inside protected areas, 17% in Indonesia and 14% in DRC, suggesting that the great majority of primate populations remain vulnerable. We list the key challenges faced by the four countries to avert primate extinctions now and in the future. In the short term, effective law enforcement to stop illegal hunting and illegal forest destruction is absolutely key. Long-term success can only be achieved by focusing local and global public awareness, actively engaging with international organizations, multinational businesses and consumer nations to reduce unsustainable demands on the environment. Finally, the four primate range states need to ensure that integrated, sustainable land-use planning for economic development includes the maintenance of biodiversity and intact, functional natural ecosystems.

[Background] Poaching is a prominent source of 'hidden hurdles', cryptic impacts of human activities that may hinder the conservation of animal populations. Estimating poaching mortality is challenging, as the evidence for illegal killing is not outwardly obvious. Using resighting and recovery data collected on 141 marked red deer Cervus elaphus within the Stelvio National Park (central Italian Alps), we show how multievent models allow to assess the direct impacts of illegal harvesting on age- A nd sex-specific survival, accounting for uncertainty over mortality causes. ; [Results] Mortality caused by poaching was consistently higher for males than for females in all age classes. In males, the probability of dying from poaching was higher for extreme age classes, while in females all age classes showed fairly similar values of poaching mortality. The strong bias in sex-specific poaching mortality was possibly due to trophy killing in adult males and 'bushmeat-like' killing for private or commercial gain in young males and in females. ; [Conclusions] A robust assessment of age- A nd sex-specific prevalence of poaching in wildlife populations is pivotal when illegal killing is of conservation concern. This provides timely information on what segment of the population is most likely to be affected. Besides obvious demographic consequences on small populations, age- A nd sex-biased poaching prevalence may contrast with the need to maintain ecosystem complexity and may alter behavioral responses to human presence. The information provided by multievent models, whose flexibility makes them adaptable to many systems where individual-based data is part of population monitoring, offers a support to design appropriate strategies for the conservation of wildlife populations. ; To conduct the research leading to these results, LC has received funding from the People Programme (Marie Curie Actions) of the European Union's Seventh Framework Programme (FP7/2007–2013) under REA grant agreement n° [609305].

Understanding the forces that drive decision-making by stakeholders is a crucial aspect in developing successful strategies for natural resource management. Empirical knowledge is only one of these drivers, as practices are also decided by individuals' beliefs, perceptions and interests, by the assets available and the institutions and norms dictating what is acceptable. Uncovering the underlying reasons for individual management decisions thus requires integrated approaches, and is particularly relevant to ensure the engagement of local communities and the effective implementation of community-based initiatives. Throughout the Colombian Amazon communities carry out subsistence as well as small-scale commercial bushmeat hunting. Overharvesting, together with habitat loss, poses a dual threat to biodiversity and to the people who depend on it for food and income: the hunters and their families. Having empirical knowledge and being aware of the high stakes if the resource crashes, hunters might have developed effective strategies for game management. Given this, we wanted to explore how hunters perceive and handle the well-known trade-off between biodiversity conservation and socio-economic development, particularly in the context of the Ticoya indigenous reserve in the Colombian Amazon. To this end, we used ReHab, a role-playing game that revolves around the management of a renewable resource. Players are either Harvesters that need to feed their families using the resource, or Park Managers seeking to protect a migratory bird sensitive to resource level and human disturbance. ReHab allows players to explore the concepts of natural resource management and sustainability when dealing with conflicting agendas and partial knowledge. The game has been played in multiple occasions in different contexts, creating a benchmark against which to compare sessions played within the culturally homogeneous group of the Ticoya hunters. We found a positive effect of communication and monitoring on the outcome indicators of conservation and development measured during the game sessions. Incomplete information and the lack of enforcement power did not prevent players to successfully resolve the trade-off and satisfy their contrasting agendas. Acknowledging the gains and losses imbedded in the decision-making process results in better designed and more resilient co-management strategies that take into account the individual and local communities' perceptions and expectations.

There is great geographical overlap between key areas of natural resources, global biodiversity and regions of acute poverty. The world's poorest people, including 59% of the population of Asia, Africa and Latin America live in rural areas alongside great natural resources on which they heavily rely for food source and income generation. However, proximity does not imply free unlimited access and often involves a great deal of trade-offs and risk ranging from natural weather and catastrophic shocks affecting resource availability, productivity and even human lives, to changes in governance and resource use regulations. In this dissertation, I study the linkages between natural resources use, livelihoods, governance and the environment, using the case study of Madagascar, a low-income country with great biodiversity and natural resources endowment. In particular, I study how different types of regulations and restrictions affect household resource use and well-being. In Chapter 1, I evaluate the health and wealth trade-offs of the widely practiced fire use in agriculture in Madagascar, using high-frequency satellite data to model pollution exposure taking advantage of random variation in wind direction. In Chapter 2, I study how poor households cope with natural disasters using the quasi-experiment setting of high frequency cyclones in Madagascar. In Chapter 3, I take advantage of a unique dataset coupled with the staggered rollout of a biodiversity conservation policy to study the impacts of community-based conservation on bushmeat hunting in northeastern Madagascar.In the first chapter, I study the impacts of agricultural fires on local health and on agricultural productivity in Madagascar. Every year, despite agricultural fires being illegal, 25% to 50% of grasslands and 7% to 10% of forests are set on fire due to slash-and-burn agriculture and livestock farming. This leads to great pollution throughout the island, yet there is limited empirical evidence on the health impacts of fires in the island. I first estimate the health impacts of fires by using high frequency and high resolution satellite data on fire location and wind speed on the day of fire to model pollution exposure around population centers. Identification comes from the random variation in wind direction and the frequent change in pollution source. I find that agricultural fires greatly impact birth outcomes and respiratory health of infants and that fires are responsible for over 4,000 "missing infants", or 0.7% of all births across the island every year. To identify the agricultural impacts of fires, I use an instrumental variable strategy taking advantage of a rapid expansion of protected areas in Madagascar that led to tripling of protected areas and delimitation of numerous potential parks. I use proposed parks, areas that were physically delimited as potential official protected areas, as an instrument for fires. Delimitation of proposed parks led to reduced fire activity, however, since parks were not actually implemented, surrounding populations were unaffected by potential economic returns or changes in behavior that would raise concerns regarding the validity of the exclusion restriction. Grassland fires led to increased livestock production and yields for cassava and corn, whereas forest fires increased corn farming land and harvest, leading to decreased food prices. These quantity and price effects increased consumer surplus by USD1.884 billion per year, implying that, for the output gains to outweigh the mortality impacts, one would have to assume a value of statistical life of less than USD440,000, whereas typical values for VSL range from 4 million to 9 million USD. Therefore the mortality costs of fires alone, excluding hospitalization costs and morbidity, exceed the benefits from increased agricultural production. Given that land use rights are ambiguous and government resources in regulating forest fires are limited, a more cooperative and integrative approach such as payments for ecosystem services might be effective in incentivizing farmers to engage in less frequent more sustainable fire activity.In the second chapter, I use cyclone track data and hourly wind direction data to model cyclone exposure and study the impact of tropical storms in Madagascar. Madagascar is the second most exposed country to multi-disaster risks in Africa, and experiences multiple episodes of droughts, floods, locust invasions and cyclones every year. On average, the island yearly experiences three to five cyclones that claim 10% to 30% of annual GDP in post-disaster losses and damages. Indeed, 74% of total labor is employed in agriculture, furthermore, agricultural products including exports amount to 45% of GDP. Yet, there is little government effort in terms of risk mitigation, resilience building and even disaster relief. Looking at the impact of cyclones on household well-being along multiple dimensions, I find that both rural and urban households are negatively impacted by cyclones in Madagascar despite better infrastructure and less reliance on natural resources in urban areas. While rural areas experience more physical losses than urban areas as measured by cyclone e↵ects on housing and access to electricity, rural households are able to smooth consumption and are less prone to cyclone-driven poverty compared to their urban counterparts. In this latter group, average cyclones have no significant impact on physical assets, but lead to lower consumption and higher rates of transient poverty. I show that this is the result of a strong informal safety net between rural and urban families through informal insurance and relief in the form inter-household transfers. To provide relief to rural families, urban households reduce expenditure in non-food expenditure including education. This suggests that, while partially effective in managing risk and achieving consumption smoothing along some key dimensions, lack of formal insurance diverts resources away from potentially productive investments such as education and towards unequivocally necessary informal relief.In the third chapter, I use a unique household-level panel data to evaluate how community- based conservation impacts bushmeat or wildlife hunting and consumption in the northeastern rainforests of Madagascar, where lemurs, bats, carnivores, tenrecs and bush pigs are commonly consumed to satisfy nutritional needs. Taking advantage of the staggered rollout of the policy, I find that community-based conservation has decreased overall hunting in the study area by reducing opportunistic hunting and hunting by less reliant, richer house- holds. This effect was larger among relatively more educated households. Furthermore, community-based conservation successfully modified consumption patterns among poorer households such that illegal hunting (hunting of lemurs and bats) was reduced and substituted by hunting practices conforming with conservation practices (seasonal hunting of sustainable prey). While these results are encouraging given the increasing shift towards decentralization, it is important to note that, in my study setting, community-based conservation was found to have some limitations. First, effects did not persist and faded over time. Second, not all types of hunting were successfully reduced and the policy led to increased active hunting through weapons and traps as households respond by retaliating and over- extracting resources in fear of completely losing access in the future. The effectiveness of community-based conservation on opportunistic hunting and bushmeat purchase was found to be heterogeneous based on income and education. Better community integration and dissemination of community conservation design principles is therefore recommended as it has proven to effectively reduce illegal hunting and also has the potential of solving the retaliation and fear-based extraction behavior. Furthermore, given that biodiversity is a global public good, local users should not be the only bearers of conservation costs and alternative livelihood strategies need to be introduced for the long-run success of conservation efforts.

Primates are traded yearly in the tens of thousands for reasons such as biomedical research, as trophies and pets, for consumption and to be used in traditional medicine. In many cases, this trade is illegal, unsustainable and considered a major impediment to primate conservation. Diurnal primates make up the vast majority of this trade, but recent studies have found that the trade in nocturnal primates is more common than previously thought, and among them are the galagos. There are currently 19 galagos recognized but there is still a dearth of research on these species and subspecies. The purpose of our study was to provide a more comprehensive picture of the trade in galagos within and across their African range countries, to help determine whether it is illegal or its sustainability needs to be assessed, and to provide baseline data and management recommendations to better regulate this trade, including strengthening policy, enforcement and conservation interventions. We gathered information on trade and use of galagos using an online questionnaire (May–August 2020), and on country-specific legislation relating to wildlife trade, hunting and legal protection of galagos, and looked at each range country's Corruption Perception Index score to gain an understanding of the obstacles in the way of effective law enforcement. We received 140 responses to our online questionnaire, from 31 of the 39 galago range countries. Respondents from 16 of these countries reported on first-hand observations of galagos being traded or used. Out of these, 36% reported seeing galagos sold or used for consumption, 33% as pets and 25% had observed them sold or used for traditional practices (including medical and magical purposes and for witchcraft). Most reports came from West Africa followed by Central Africa, East Africa and Southern Africa. We found that the number of reports on galagos being traded was higher in countries with higher numbers of galago species. Countries with more restrictive legislation experienced a higher number of reports of trade. Galagos observed in the pet trade was more common in East Africa, whilst reports of them in the bushmeat trade were more common in Central and West Africa. Galagos observed in the trade for traditional practices was by far most common from West Africa. We found that all galago range countries have some level of legal protection for some or all of their native galago species. It is evident that use and trade of galagos occurs throughout their range, albeit localized to certain areas. We urge galago range countries to adequately protect all species and to ensure legal trade is effectively regulated. Range countries that prohibit the use and trade in galagos must ensure legislation is adequately enforced. Further research into the drivers behind the use and trade of galagos should be initiated in countries with high levels of use and trade to further inform conservation and policy actions and to catalyze enforcement actions against poaching and illegal trade.

Background: Owing to the extreme virulence and case fatality rate of ebola virus disease (EVD), there had been so much furore, panic and public health emergency about the possible pandemic from the recent West African outbreak of the disease, with attendant handful research, both in the past and most recently. The magnitude of the epidemic of ebola virus disease has prompted global interest and urgency in the discovery of measures to mitigate the impact of the disease. Researchers in the academia and the industry were pressured to only focus on the development of effective and safe ebola virus vaccines, without consideration of the other aspects to this virus, which may influence the success or otherwise of a potential vaccine. The objective of this review was to adopt the SWOT concept to elucidate the biological Strengths, Weaknesses, Opportunities, and Threats to Ebola virus as a pathogen, with a view to understanding and devising holistic strategies at combating and overcoming the scourge of EVD. Method: This systematic review and narrative synthesis utilized Medline, PubMed, Google and other databases to select about 150 publications on ebola and ebola virus disease using text word searches to generate the specific terms. Relevant publications were reviewed and compared, findings were synthesized using a narrative method and summarized qualitatively. Results: Some of the identified strengths of ebola virus include: Ebola virus is an RNA virus with inherent capability to mutate, reassort and recombine to generate mutant or reassortant virulent strains; Ebola virus has a broad cellular tropism; Natural Reservoir of ebola virus is unconfirmed but fruit bats, arthropods, and plants are hypothesized; Ebola virus primarily targets and selectively destroys the immune system; Ebola viruses possess accessory proteins that inhibits the host' immune responses; Secreted glycoprotein (sGP), a truncated soluble protein that triggers immune activation and increased vascular permeability is uniquely associated with Ebola virus only; Ability to effectively cross the species barrier and establish productive infection in humans, non human primates, and other mammals; Ebola virus attacks every part of the human body; The Weaknesses include: Ebola virus transmission and persistence is severely limited by its virulence; Ebola virus essentially requires host encoded protein Niemann–Pick C1 (NPC1) for host's cell' entry; Ebola virus essentially requires host encoded proteins (TIM-1) for cell' entry; Relative abundance of Ebolavirus Nucleoprotein than the other virion components; The Opportunities harnessed by ebola virus include: Lack of infection control practices in African health-care facilities and paucity of health infrastructures, especially in the endemic zones; Permissiveness of circulating Monocytes, Macrophages and dendritic cells in virus mobilization and dissemination; Collection, consumption and trade of wild games (bushmeats); Pertubation and drastic changes in forest ecosystems present opportunities for Ebola virus; Use of dogs in hunting predisposes man and animals to inter-species contact; Poverty, malnutrition, crowding, social disorder, mobility and political instability; Ease of travel and aviation as potentials for global spread; Possible mechanical transmission by arthropod vectors; No vaccines or therapeutics are yet approved for human treatment; The Threats to ebola virus include: Avoidance of direct contact with infected blood and other bodily fluids of infected patient; Appropriate and correct burial practices; Adoption of barrier Nursing; Improved surveillance to prevent potential spread of epidemic; Making Available Rapid laboratory equipment and procedures for prompt detection (ELISA, Western Blot, PCR); Sterilization or disinfection of equipment and safe disposal of instrument; Prompt hospitalization, isolation and quarantine of infected individual; Active contact tracing and monitoring, among others. Conclusion: The identified capacities and gaps presented in this study are inexhaustive framework to combat the ebola virus. To undermine and overcome the virus, focus should be aimed at strategically decreasing the identified strengths and opportunities, while increasing on the weaknesses of, and threats to the virus.

Includes bibliographical references. ; The abundance of African lions Panthera leo has declined rapidly in recent decades, largely due to competition for space with growing human populations. The future persistence of the species in the wild therefore depends heavily on viable populations in large protected areas, where lions play key ecological and economic roles. Zambia is one of nine countries estimated to have over 1000 wild lions, and Kafue, its largest national park, is a key refuge for the species. In this thesis I aimed to address the paucity of management and conservation relevant data on Kafue's lion population. I first used a track-based occupancy survey to determine the broad-scale drivers of lion distribution in the park. My results did not support my a priori expectations of anthropogenic edge effects driving lion occupancy; instead favourable habitat emerged as the best predictor of dry season lion distribution. The lack of edge effects is likely a result of the uniform suppressive effect on prey biomass of ubiquitous illegal bushmeat hunting in Kafue. After using my occupancy results to stratify my study area, I tested the effectiveness and efficiency of two well-established survey methods, track counts and call-up surveys, by comparing the resulting density estimates with that of a reference sample of GPS-collared lions in the study area. Accuracy of the two results was comparable, but the call-up estimate was more precise. However, call-up surveys are subject to variation in response rates that is difficult to quantify. I thus recommend that track count surveys are more suitable for monitoring lion population trends in Kafue. I further provide the first robust density estimate for northern Kafue of 1.83 lions (>1yr old) per 100 km2. Understanding how animals use space is fundamental to their conservation. I therefore used GPS collars to investigate lion spatial ecology at a finer scale, and the effects thereon of the seasonal flooding of large parts of Kafue. Home range sizes were comparable to those of other lion populations in the region. However, seasonal inundation caused lions to expand home ranges, travel greater distances and shift away from favourable habitat in the wet season, potentially contributing to apparent high cub mortality rates. The combination of these factors may limit the resilience of the population in the face of identified local anthropogenic threats (i.e. illegal hunting of ungulates and lions, legal trophy hunting of lions and frequent, uncontrolled bushfires). I provide both direct and indirect evidence of such threats, and conclude that lion abundance in Kafue is limited primarily by the suppressed prey population, while the extent and regularity of bushfires may also have adverse effects. I recommend stronger enforcement of existing regulations pertaining to illegal hunting and fires, and the implementation of recently developed monitoring software to improve the efficiency and effectiveness of limited law enforcement resources. I further conclude that lion hunting quotas were excessive prior to the 2013 ban on hunting in Zambia, and suggest that the ban remain in place for at least three years to enable adequate recovery of the population. If the Zambian government elects to lift the ban, I propose a total combined quota of 5.25 lions per annum for the hunting concessions surrounding Kafue. I further recommend the implementation of strict age-based regulations within a robust adaptive management framework, based on the best available scientific data, to ensure the sustainability of harvest. To evaluate the effectiveness of such management interventions I propose long-term monitoring of lion abundance and distribution in Kafue using annual track count surveys. This study highlights that even the largest of Africa's national parks cannot ensure the survival of flagship apex carnivores. My findings and recommendations may be applicable to other wild lion populations in large protected areas where data paucity limits management effectiveness. Understanding and managing threats to these protected areas at the appropriate scale is critical if they are to meet their conservation objectives and ultimately ensure the persistence of wild lion populations.

Various authors have used different categories to estimate the value of wildlife, e.g. direct and indirect use values, option values, ethical values, etc. ln this paper, the authors address the value of wildlifebased tourism. With the development of the worfd tourism industry, the value of nature-oriented tourism is increasing on aff continents, and especially in sub-Saharan Africa. The value of such tourism is often understood as the direct economie benefits that come from "the tourist dollar' and contribute to the generation of incarne for the country and its inhabitants. However, there are other ways to value wildlife which are not sufficiently taken into account, i.e. the diverse benefits provided by ecosystem services, such as the eco/ogical value of species to a healthy ecosystem, their nLJtritiona/ value and cultural value, etc. Wildlife tourism in sub-Saharan Africa is large/y supported by Protected Areas (PAs), with their broad range of different categories, which are clearly the backbone of the industry. One leg of wildlife tourism is the wildlife-viewing tourism in natural habitats. ln sub-Saharan Africa, this type of tourism main/y occurs in PAs of the public domain, principal/y national parks (NPs). ft also occurs at a few other locations, such as game ranches which are privately owned, or communal conservancies which are community-based, bath found main/y in Southern Africa. With a few notable exceptions, a majority of NPs are struggling to fu/fil their conservation mandate, due to a Jack of financia/ and hu man re sources for the ir management: very few of them attract enough tourists to co ver their management costs. At present, most NPs require externat funding to support their day-ta-day running and achieve their conservation aims. This is nothing new. Protected areas cannat be justified sole/y by their direct economie outputs; the entire range of benefits that they provide must be considered. The other /eg of wi/dlife tourism is hunting tourism. This type of tourism main/y occurs in public/y owned PAs, which are official/y gazetted and earmarked as hunting areas (HAs) under various names (e.g. game reserves, hunting blacks, Coutadas, Zones de Chasse, Domaines de Chasse, etc.). ln a few Southern African countries, hunting tourism is a/so carried out on private and communal land. These HAs, averai/ much bigger than NPs, often a ct as buffer zones around and ecological corridors between NPs. They are usual/y private/y managed and financed and thus their contribution he/ps to reduce the financial burden on the government, of conserving and managing its biodiversity assets in these areas. Go vern ment budgets for conservation are often under-resourced, being law on the list of national development priorities. Thus, improved professionalism and efficiency in the hunting tourism industry could substantia/ly increase the ability to conserve huge tracts of natural habitat, with al/ of their biodiversity and ecosystems services, while increasing economie benefits to the local people and Government. However, most PAs are under threat from humans, caused by growing populations and their increasing need for land and natural resources. ln developing countries, concerned with food security and poverty a/leviation, poaching is a widespread threat to PAs. The often massive quantity of bushmeat taken from bath inside and outside PAs represents a kind of 'hidden' value, since it is large/y unknown, over/ooked and often illegal. When this direct consumption of game for food becomes unsustainable, due to over-harvesting the resource, its value becomes negative and counter-productive to wildlife tourism. Agriculture encroachment is a severe threat to PAs because it is converting natural habitats, destroying biodiversity and compromising ecosystem services. Pastoral encroachment is a relative/y new threat to NPs and HAs, and this issue is often neglected in management schemes although it is happening more frequent/y. The two diffe

Before the First World War, politicians of the great powers blustered at each other, believing they defended their national interests. Today they are remembered for provoking the deaths of 15 million people. Before WWII, Germany and Japan each felt they had been deprived of their rightful place in the world. That attitude spawned their expansionist régimes. Seventy million people died. In Copenhagen today politicians from rich and poor nations claim their right to spew the planet's carbon into our atmosphere. There is a difference: the negotiators today in Copenhagen already know that if they fail, they will be responsible not for a few millions but for hundreds of millions of deaths, and misery for billions. Madagascar is one of many places that people will die from the changing climate. The last decade averaged 2 true cyclones each year, not counting 2-4 more large tropical storms. Science is unclear whether storms and cyclones will become more frequent, but all predictions agree that warming sea temperatures will make them more intense and destructive. And as people of Madagascar's east and west recover from cyclones Fanele, Eric and Jade, drought ravages the south — no one is sure how the rains will change, only that change is coming. Politicians within Madagascar have little say in the negotiations of Copenhagen, but they have the same problem of balancing short-term advantage over long-term gain. Do they want to spend their time only in political manoeuvers for their parties' gain? If so, they will be remembered for letting people go hungry and allowing the destruction of Madagascar's extraordinary natural heritage. Rosewood export from the national parks and lemur sale as bushmeat are theft from the people of Madagascar, and from the people's future. Even hungry farmers look to the future. A farmer must be at the last extremity before he or she eats the seed they have saved for next year's planting. Can the politicians of Madagascar and the wider world look beyond this year, beyond this round of elections or negotiations? Do they wish to be remembered as the mothers and fathers who protected their countries' people and the world's heritage of nature, or else like politicians of Europe before the great World Wars, as murderers of the future?PRÉFACEUne lettre sur la politique Avant la Première Guerre mondiale, les politiciens des grandes puissances se déchaînaient les uns contre les autres en pensant défendre les intérêts de leurs nations. Aujourd'hui on se rappelle d'eux pour leur responsabilité dans la mort de 15 millions de personnes. Avant la Deuxième Guerre mondiale, l'Allemagne et le Japon estimaient avoir été spoliés de la place qui leur revenait dans le monde, attitude qui engendrera leurs régimes expansionnistes. Soixante-dix millions de personnes sont mortes. À Copenhague aujourd'hui, des politiciens de pays riches et de pays pauvres revendiquent leur droit de répandre le carbone planétaire dans l'atmosphère. Mais il y a une différence, car ceux qui négocient aujourd'hui à Copenhague savent que s'ils échouent, ils seront responsables, non pas de quelques millions de morts, mais de centaines de millions de morts et de la misère de milliards d'hommes, de femmes et d'enfants. Madagascar est un endroit parmi tant d'autres où les gens mourront du changement climatique. La dernière décennie a été marquée par deux vrais cyclones par an en moyenne, et quelques deux-quatre tempêtes tropicales importantes. Il subsiste bien encore quelques doutes pour prouver scientifiquement dans quelles mesures les tempêtes et les cyclones augmenteront en fréquence mais toutes les prévisions s'accordent au moins pour admettre que l'augmentation de la température des océans les rendra plus intenses et plus destructeurs. Et alors que les gens de l'Est et de l'Ouest de Madagascar se remettent des cyclones Fanele, Éric et Jade, que la sécheresse ravage le Sud, personne ne sait comment les pluies évolueront mais tous s'accordent à reconnaître que changement il y aura. Les politiciens de Madagascar ont peu de poids dans les négociations de Copenhague, mais sont confrontés au même problème qui consiste à faire la part des avantages à court terme par rapport aux gains à long terme. Veulent - ils se borner à quelques manoeuvres politiques pour en faire profiter leurs partis ? Si c'est le cas, on se rappellera d'eux comme ceux qui ont laissé les famines s'installer dans leurs pays et permis la destruction du patrimoine naturel extraordinaire de Madagascar. L'exportation des bois précieux des parcs nationaux et la vente de lémuriens comme gibier sont des vols commis contre les citoyens de Madagascar et contre le futur de l'humanité. Même les fermiers affamés envisagent l'avenir. Un fermier ou une fermière doit être au bord du désespoir avant de manger les graines qui devraient servir de semences aux plantations de la saison suivante. Les politiciens de Madagascar et du monde peuvent-ils regarder au delà de cette année, au delà de cette série d'élections ou de négociations ? Souhaitent - ils rentrer dans les mémoires comme les mères ou les pères qui ont protégé les citoyens et le patrimoine naturel mondial de leur pays, ou comme les politiciens de l'Europe avant les Grandes Guerres, comme des meurtriers du futur ?

The attachment that we feel to Madagascar compels us to talk about it – its richness, its values, its people and about life lessons learned and taught. As these experiences may differ in many aspects, a journal is the ideal place for sharing our common ideas, as well as expressing our divergent thoughts and theories. It is also a conduit for the exchange and transmission of our ideas and perspectives to the world. Thus, it is the ambition of this journal to talk about Madagascar – it's natural richness and its conservation, about development and challenges in the country, and more generally about components and facets of conservation and development. In this volume, the Journal launches two new rubrics, which emerged from the energetic enthusiasm of the authors, editors and our friends. Words are not the only way to formulate and share stories, pictures can carry messages as well; and they can speak without using words while still diligently evoking emotions and reactions in all of us. Now, we want to hear what your reactions are; we need to hear and to read how images from Madagascar capture and affect you. The Journal is doing this for the very first time and no matter who, whether men, women, or children, all of them have voiced their feelings about the photo of the little girl on the front cover of this volume. We want you to participate in Voicing Over Pictures, to share your ideas, for those of you not having a scientific based project ready yet, or simply to tell your experience in a different way. For example, those who have the courage to circulate photos and stories about the dead stranded dolphins of the port of Antsohihy. They suspected a link between the sonar systems of Exxon Mobil and the dolphins' navigation off the coasts of Analalava and Antsohihy (and they may be right, as such correlations are scientifically proven in peer - reviewed publications) even though they did not want to believe that such a tragedy could happen in their Madagascar. These people felt motivated to reach out into the world and show us what is happening. Madagascar can sometimes seem too far away from the rest of the world but this story brings us back to our sense of place in the country. Some pictures have been circulated but lately there has been only a dull silence, as scientists take time to research the issue and publish the evidence that they find. We have received a broad variety of contributions to this volume such as "Bats as bushmeat in Madagascar". This is not only the first MCD review focussing on Madagascar's bats, but it also shows some impressive pictures including a rather unusual and unfortunate shot of bats in a context that is more common than you think: the bat on the dinner plate. Another contribution addresses one of the top 25 most endangered primates in the world. Instead of resigning and continuing what others of their ilk have done for generations (and seriously risking a listing in the history books under the chapter 'Extinct') the White - collared brown lemur has adapted to new and changing situations and has even been flexible enough to tackle the aftermath of cyclones and start feeding on mushrooms and spicy invasive plants. Is this a recipe for survival? We shall see. In another story, the authors of the Manambolomaty Lake Project draw on local taboos and beliefs to establish a conservation framework for the protection of natural resources – a success story showing how important the traditional knowledge and culture of the local people is to achieving conservation that really matters. Sharing information is important, that is nothing new. Before you can share, however, you need the ability to access it. In a piece about the power of radio, the authors show that radio broadcasting can be utilized beyond the daily spread of news and entertainment: it can also be an effective tool for community outreach. This has so far been 'off the radar' for most international aid agencies. Broadcasting information and knowledge over the radio can be an effective tool in the fight to alleviate poverty; which is so far still the biggest challenge in Madagascar. As our words mark the passage of time into history, then you will be part of Madagascar's history of tomorrow. MCD is presenting another new rubric; Travelling Through Time will be talking about people who have written Madagascar's history in the past century, about people who were building on Madagascar's milestones for present and future conservation and development endeavours. There are people who have been participating in Madagascar's history. Some of them are almost living legends; they have made their imprints on this island; and whether they are appreciated or not, people talk about these personalities. At the beginning of the 19 th century oil mining industries (often with governments in the background) were endorsing renowned geologists for their endeavours such as Raymond Decary (1891 - 1973) who over the years became an accomplished humanist and naturalist. There is also the story of Charles A. Domergue, a hydro - geologist who also ended up dedicating his life to development in southern Madagascar where he pursued scientific studies and the conservation of the biological riches of Madagascar that mesmerized him. We invite you to talk in Travelling Through Time about your own heroes, men and women who have been the pioneers and advocates for Madagascar's Conservation and Development. Returning to the picture as a medium of information, some of these are also meant to satisfy the classic clichés, the ones that reinforce stereotypes that the rest of the world has about Madagascar. Madagascar is a country of the South, and the world expects to see pictures mirroring these characteristics. In the South, mining is often married with the traditional picture of gold miners: deep pits bored by using the angady (the Malagasy spade), causing sweaty and muddy foreheads on the miners' emotionless faces while the mining dumps grow bigger and taller. One might think of a new Germinal or Assommoir - like novel of Emily RaZola's, with the toka Gasy replacing the absinthe, with the North pointing fingers and watching the South. However, the question remains, what is the real picture? Modern mines are equipped with sophisticated exploitation tools, and the companies have the backing of conduits of social and environmental impact studies, employing an international guild of workers, efficient and trained in using the latest technology, rearing to go. The Journal would like to call upon people who know about these mining activities and who are studying specific social, economic and environmental impacts; people who also are aware that these activities are unavoidable, and people who know that tropical forests are disappearing quickly from the maps of Madagascar, and with them the Indris that sing no longer, crying if they only could. We need these people to tell their stories and share their expertise and experience, since we all want to know and would like to understand what the benefits and negative impacts of large - scale mining or farming are for Madagascar. The Journal would like to emphasize one more time that sharing information between agencies (governmental and non), universities and private persons is crucial. Whether you are in the field, in a forest, a community or a laboratory; sharing and informing is the most important step to moving Madagascar further ahead! You can simply share your impressions of the breath - taking photo on this volume's cover (which has been kindly contributed by Peter Oxford and Reneé Bish); as college students, children and older people have done, or you can go further and contribute more to the information sharing in the pages of this Journal. Submit us your stories and impressions as photo essays, or bring your experiences and findings to paper and send us articles, reviews or essays. We are sure you will enjoy the articles in this issue and we hope to see more in the near future.Image en Action Comme tous ceux qui sont affectivement attachés à Madagascar, nous aimons parler de cette grande île, de ses richesses, de ses valeurs profondes, de ses gens, des leçons de vie qu'ils nous ont inculquées, mais si nos expériences aux uns et aux autres ont Madagascar en commun, elles diffèrent certainement en tous points et un journal est ainsi le lieu idéal pour échanger nos points de vue. Ici nous voulons parler des richesses naturelles de Madagascar et de leur protection, de développement et des défis à relever, ou un seul aspect lié à la protection de la nature ou au développement mais surtout et avant tout, nous invitons des hommes et des femmes à prendre la parole. Le journal lance ainsi deux nouvelles rubriques qui sont nées de l'enthousiasme des auteurs, des éditeurs et de nos amis qui partagent tous cette même volonté de communiquer ; les mots sont loin d'être les seuls outils de communication et si nous ne pouvons employer tous les moyens ici, nous savons cependant que les images véhiculent bien des messages, ont cet incroyable pouvoir de nous émouvoir et nous parlent. Et nous avons besoin de vous, de vous entendre, de vous lire, comme nous l'avons fait ici lorsque nous avons donné la parole à des femmes, des hommes et des enfants pour qu'ils nous disent avec leurs mots, leur sensibilité, ce qu'ils ont entendu dans les yeux de cette enfant. Et nous vous attendons pour participer à cette rubrique 'Voicing Over Pictures' ou 'Paroles d'Images' pour partager vos idées, pour communiquer en attendant d'avoir matière à produire un article scientifique, ou pour le dire autrement. Nous pensons par exemple à ceux d'entre vous qui ont eu le courage de faire circuler ces photos de dauphins échoués dans le port d'Antsohihy. Certains ont soupçonné un rapport entre les sonars à balayage latéral d'Exxon Mobil et l'échouage des dauphins sur les côtes proches d'Analalava et d'Antsohihy, ils ne peuvent pas avoir tort car tout cela est connu depuis bien longtemps ; de tels faits sont scientifiquement prouvés et publiés dans des revues à comité de lecture, mais ceux qui constataient les faits sur les côtes malgaches ne voulaient tout simplement pas croire que cela se passait aussi chez eux, en étaient émus, voulaient le hurler, et très fort car Madagascar est parfois tellement loin du reste du monde ! Quelques photographies circulèrent mais furent rapidement remplacées par un silence pesant car la science a besoin de bien plus d'éléments et qu'il lui faut du temps pour procéder aux recherches et mettre ses résultats sous presse. Nous avons reçu des contributions variées pour ce volume et pour n'en citer que quelques unes, l'article « Bats as bushmeat in Madagascar » est une première sur les chauves-souris pour le journal mais qui nous montre des images impressionnantes de ces animaux dans un contexte qui n'est pourtant pas inhabituel, celui où ils se retrouvent accommodés dans une assiette. Un autre article concerne l'un des 25 primates les plus menacés du Monde. Et plutôt que de démissionner et de poursuivre comme d'autres de la lignée l'avaient fait pendant des générations (pour prendre inéluctablement le risque d'aller rejoindre les livres d'Histoire sous la rubrique 'Éteints'), le Lémurien à collier blanc montre qu'il s'adapte à une situation changeante en étant capable de composer dans une forêt ravagée par un cyclone et de s'alimenter de champignons et de fruits épicés d'espèces allogènes ; recette pour survivre ou non, il s'agit pour le moment d'une affaire à suivre. Les auteurs de l'article sur le projet du lac Manambolomaty s'inspirent des croyances et des tabous locaux pour mettre en place un réseau destiné à la protection des ressources naturelles – l'histoire d'une réussite qui relate une fois de plus à quel point les gens sont importants pour protéger une nature qui compte. Partager l'information est primordial et ceci n'est pas un scoop ! Mais avant de pouvoir partager il vous faut les moyens de le faire comme il est montré ici dans l'article sur la radiodiffusion qui peut aller au - delà de la transmission de nouvelles et de divertissement en constituant un outil capable de s'adresser aux communautés les plus isolées et qui étaient loin de toutes les priorités des agences d'aide internationales. La radio peut constituer un outil de choix pour lutter contre la pauvreté qui reste encore et par - dessus tout le plus grand défi à relever à Madagascar. Ainsi, les mots marqueraient - ils le passage du temps dans l'Histoire, de sorte que vous êtes alors tous la future Histoire de Madagascar. Dans ce contexte, le journal présente donc une autre rubrique pour parler des gens qui ont écrit l'histoire du siècle dernier de Madagascar, de ceux qui ont posé des jalons sur la route de la conservation et du développement présents et futurs de l'île. Car il y a des gens qui ont participé à cette Histoire, parfois des légendes vivantes qui ont marqué l'île de leur empreinte, on les aime ou non mais on parle d'eux. Au début du XIXe siècle, les explorations pétrolières firent appel à d'éminents géologues et nous nous rappelons de Raymond Decary (1891 - 1973) qui est, par la suite, devenu un humaniste et un naturaliste chevronné. Plus jeune, un autre géologue a partagé un destin semblable en consacrant sa vie au développement du Sud de Madagascar ainsi qu'à la science et la protection de ses richesses naturelles, ce naturaliste est Charles A. Domergue. Dans Travelling Through Time ou Voyage dans le Temps, nous donnons la parole à ceux qui veulent nous parler de leurs héros, de ces hommes et ces femmes qui ont marqué l'histoire de la protection de la nature et du développement de Madagascar. Pour revenir aux paroles émanant des images, il nous faut admettre que certaines d'entres elles sont aussi destinées à contenter les clichés, ces caricatures qui rassurent et qui doivent traduire la bonne marche du monde. Madagascar est un pays du Sud et le monde veut y voir des images du Sud. Dans le Sud, l'exploitation minière se marie avec l'orpaillage traditionnel, des puits profonds creusés à la sueur du front, des terrils érigés à la force des angady (les pelles locales) dans une ambiance où on frôle un nouveau 'Germinal' ou 'Assommoir' d'un Émile RaZola où le toka gasy (rhum local) remplacerait l'absinthe dans le Sud qui sera pointé du doigt par le Nord. Mais savons - nous seulement à quoi ressemble la réalité ? L'exploitation minière moderne met en place des chantiers élaborés, des moyens d'extraction sophistiqués, se contraint à réaliser les études sociales et d'impact environnemental conformément à des normes internationales, fait appel à des travailleurs et experts de toutes nationalités, efficaces et rompus à utiliser les dernières technologies en la matière. Le Journal voudrait donc inviter ceux qui connaissent ces activités minières, qui étudient spécifiquement les impacts sociaux, économiques et environnementaux mais aussi tous ceux qui admettent qu'il n'y a généralement pas le choix, qui savent que des forêts tropicales disparaissent rapidement de la carte de Madagascar, et avec elles des Indris qui ne chantent plus mais pleureraient s'ils le pouvaient ou si nous pouvions les entendre. Nous avons besoin de vous entendre avec des mots, des paroles d'images et vous invitons à partager vos expertises et expériences car nous voulons tous savoir et nous voudrions comprendre ce que sont les avantages et les inconvénients des exploitations minières ou agricoles à grande échelle à Madagascar. Madagascar Conservation & Development voudrait insister une fois de plus sur le besoin de partager les informations, aussi bien celles des agences gouvernementales que non gouvernementales, des universités ou des particuliers, que des gens de terrain, qu'ils soient en forêt, dans un village ou dans un laboratoire ; le partage et l'information sont des éléments déterminants pour faire avancer Madagascar ! Vous pouvez simplement partager votre sensibilité en nous disant ce que vous voyez dans des images comme l'ont fait des collégiens, des enfants et des moins jeunes pour la superbe photo de couverture aimablement mise à disposition par Peter Oxford et Reneé Bish. Mais avant tout, le journal voudrait inviter des gens qui travaillent dans la Conservation et le Développement à participer à l'échange de l'information ! Soumettez nous vos histoires et vos impressions, sous la forme d'images accompagnées d'une courte légende, ou partagez vos expériences et vos découvertes dans des articles, des revues ou des essais. Nous sommes certains que vous apprécierez la lecture de ce numéro et espérons vous y voir davantage dans un proche avenir.
