South-South cooperation is grounded in the idea that partners from the developing world are well placed to propose solutions inspired by their own experiences. A study of the dynamics of the circulation of instruments of public policy framed in the agricultural sector between Brazil and Sub-Saharan Africa under the Lula administration (2003–2010) reveals that political entrepreneurs play a key role in the early transfer stages of this process and that a technical logic of policy transfer through South-South cooperation may pose important challenges to the later stages of reception and adaptation. A notion of complementarity between agribusiness and family farming that reflects recent governmental discourse has been influential in the formulation of initiatives.

Chenopodium quinoa Willd., a high quality grain crop, is resistant to abiotic stresses (drought, cold, and salt) and offers an optimal source of protein. Quinoa represents a symbol of crop genetic diversity across the Andean region. In recent years, this crop has undergone a major expansion outside its countries of origin. The activities carried out within the framework of the International Year of Quinoa provided a great contribution to raise awareness on the multiple benefits of quinoa as well as to its wider cultivation at the global level. FAO is actively involved in promoting and evaluating the cultivation of quinoa in 26 countries outside the Andean region with the aim to strengthen food and nutrition security. The main goal of this research is to evaluate the adaptability of selected quinoa genotypes under different environments outside the Andean region. This paper presents the preliminary results from nine countries. Field evaluations were conducted during 2013/2014 and 2014/2015 in Asia (Kyrgyzstan and Tajikistan), and the Near East and North African countries (Algeria, Egypt, Iraq, Iran, Lebanon, Mauritania, and Yemen). In each country, the trials were carried out in different locations that globally represent the diversity of 19 agrarian systems under different agro-ecological conditions. Twenty-one genotypes of quinoa were tested using the same experimental protocol in all locations consisting in a randomized complete block design (RCBD) with three replicates. Some genotypes showed higher yields and the Q18 and Q12 landraces displayed greater adaptation than others to new environmental conditions. The Q21 and Q26 landraces were evaluated with stable and satisfactory levels of yield (>1 t.ha−1) in each of the different trial sites. This production stability is of considerable importance especially under climate change uncertainty. While these results suggest that this Andean crop is able to grow in many different environments, social, and cultural considerations remain crucial regarding its possible introduction as a staple food in new cropping systems around the world.

This thesis includes four parts to characterize Buffalo milk and veal chains at different chain levels, the objectives of the first part were to identify the diversity of different chains and more deeply to determine main actors along the milk value chains in three villages to understand how these chains work. Also, milk analysis was applied to study the effect of location on milk composition, milk urea nitrogen (MUN) and somatic cell count (SCC). Field visits and interview are used to collect data. Milk samples were collected from farmers through 2013/14. Results indicated that there were a short chain and a long chain. Short chain achieved higher profit for farmers and reasonable price for consumers compared to long chain. While long chain provide s a lot of jobs. MUN, SCC and milk composition could be used as diagnostic tools for different regions to identify the most priority services and extension needs at village level. The aim of the 2nd part was to suggest a methodology to characterize the diversity of dairy farming systems in Egypt to understand the traditional dairy sector. Data were collected from 65 farmers in three villages through three consecutive seasons. Based on multiple factorial and cluster analyses, six farmer s' group were identified. Milk production was a major activity in very small land farms, the sustainability of this sector facing the lack of technical support and lack of pricing system for milk and feedstuffs, more governmental and NGOs projects needed to supply farmers with high quality forage seeds, high producing animals and veterinary services. So, considering the diversity of farming systems, one agricultural policy will not fit all farmers' categories taking into account the region and the season. The objective of the 3rd part was to apply a SWOT analysis on a traditional milk chain, particularly buffalo skimmed milk chain around greater Cairo, which considered as one of the main dairy markets in Egypt. Main stakeholders of the chain were farmers, milk collection points, milk collection center, and dairy processing units. SWOT analysis allowed highlighting the major role of social network to explain the flexibility and adaptation of this sector to the major constraints in linked with international competitiveness and national constraints, mainly on land access. These elements could help decision makers and developers to prioritize sustainable development activities in link with agriculture global agenda. The aim of fourth part was to characterize the veal supply chain using survey analysis for different actors along the chain and to understand the preference of some meat consumers to veal meat through comparing meat quality parameters of buffalo meat categories in Egyptian market including meat quality analysis of veal, fattening males and culled females. Survey analysis results indicated that 65 % of Egyptian farmers sold veal as early as possible. About 61 % of these farmers sold their animals for economic reasons, 14 % for technical reasons and 25 % for both reasons. Fat content and cholesterol levels were lower in veal meat compared with fattening calves or culled females; the same trend was observed for shear force value s and cooking loss percentage. These results explained why the veal meat is regularly consumed by elders, sick peoples and employees with limited physic al activities, veal showed high tenderness and more attractive color, in contrast veal contained lower fat and cholesterol levels.

Adaptation to climate change and its mitigation are some of the biggest challenges facing agriculture. In the global South, these challenges are associated with the need for food security. The arrival of climate change on the international agenda has prompted the recycling of a multitude of initiatives to address this problem, leading inevitably to the emergence of numerous controversies. However, although the scales and actors targeted may differ, all of these initiatives are trying in one way or another to provide technical, social, economic and political options to increase the climate resilience of agriculture. There is heated debate about three approaches, which focus on these relationships between agriculture and climate: climate-smart agriculture, agroecology and the 4 per 1000 Initiative on soil carbon. Beyond the conceptual differences and the sometimes partisan interpretations of these three approaches, agriculture in the Southern countries needs to take advantage of their potential synergies.

The transformations occurring in family-based agricultural structures are raising questions in the academic and political worlds. The questions being asked span the history of agricultural representations over the last century. The ways of perceiving and representing the different forms of agriculture relate to these transformations. Family farming has acquired an international legitimacy but is presently being questioned by agricultural evolutions in developed countries, as well as in developing or emerging countries. The Sustainable Rural Livelihoods (SRL) approach enables a global comprehension to be formed of the agricultural entity as a constituent of an activity system that has become multi-sectorial and multi-site, relating to market and non-market regulations. The relative significance and the nature of the mobilized capitals led us to schematically present six organizational forms of family agriculture in New Caledonia, Vietnam, Mali, South Africa, France and Brazil. Lastly, a more generic characterization, which our proposed agriculture representation framework outlines, is presented and raises further methodological challenges.

The surveillance of animal diseases has been the subject of numerous national and international initiatives further to the emergence, or re-emergence, of human diseases of animal origin. Noting that collaboration between stakeholders involved in surveillance was still insufficient, the international organisations have stressed the importance of harmonising data collection tools and mobilising stakeholders through participatory methods, education and communication. However, by focusing on technical constraints and individual motivations, these policies disregard the strategic role of information and potential conflicts of interest. Moreover, they ignore the practices of the many stakeholders in the field, who convey disease information within non-conventional surveillance networks. Hence the proposal to take these networks into account, without compromising the diversity of their objectives and operations, in order to make the surveillance of animal diseases more effective.

The aim of this study was to suggest a methodology to characterize the diversity of dairy farming systems in Nile valley lands (NVLs) and newly reclaimed lands (NRLs) in Egypt to understand the traditional dairy sector. Data were collected from 65 farmers in three villages through three consecutive seasons. Interviews and field visits were done at farm level. Based on multiple factorial and cluster analyses, six farmer groups were identified according to land and livestock assets, milk production and selling. Milk marketing was influenced by season, farmers' traditions, and market access. Structure highlights the dominance of small scale crop-livestock system, farm family depends on milk as a source of protein and fat for family food and as a main source of income especially in old lands, while in NRLs, there was a higher crop-livestock integration and complementarity to cover family and farm expenses, so paid services strategy could fit dairy sector in new land. Milk production constitutes a major activity in very small land farms, the sustainability of this sector facing the lack of technical support and lack of pricing system for milk and feedstuffs, where more governmental and non-governmental projects needed to supply farmers with high quality forage seeds, high producing animals and veterinary services. So, considering the diversity of farming systems, one agricultural policy will not fit all farmers' categories. Also, governmental and non-governmental services should be reasoned according to the region and the season.

Global support for Conservation Agriculture (CA) as a pathway to Sustainable Intensification is strong. CA revolves around three principles: no-till (or minimal soil disturbance), soil cover, and crop rotation. The benefits arising from the ease of crop management, energy/cost/time savings, and soil and water conservation led to widespread adoption of CA, particularly on large farms in the Americas and Australia, where farmers harness the tools of modern science: highly-sophisticated machines, potent agrochemicals, and biotechnology. Over the past 10 years CA has been promoted among smallholder farmers in the (sub-) tropics, often with disappointing results. Growing evidence challenges the claims that CA increases crop yields and builds-up soil carbon although increased stability of crop yields in dry climates is evident. Our analyses suggest pragmatic adoption on larger mechanized farms, and limited uptake of CA by smallholder farmers in developing countries. We propose a rigorous, context-sensitive approach based on Systems Agronomy to analyze and explore sustainable intensification options, including the potential of CA. There is an urgent need to move beyond dogma and prescriptive approaches to provide soil and crop management options for farmers to enable the Sustainable Intensification of agriculture.

The soaring world cereal prices in 2007/2008 and the subsequent riots in several sub-Saharan African cities reignited the debate on food security policy. Could rising world cereal prices actually be a blessing in terms of boosting food production by guaranteeing more attractive prices for farmers? This implies determining whether global price fluctuations are actually transmitted to national market prices. This was the objective of a study focusing on five countries in the region.Between 1994 and 2009, the degree of transmission of world rice prices to domestic markets varied considerably from one country to another: low or even inexistent in Mali, Cameroon and Madagascar; high in Senegal and Niger. The 2007/2008 price increases made no structural changes to the types of transmission identified over the long term.The segmentation of food markets between imported rice, local rice and other foodstuffs explains this imperfect transmission of global prices to sub-Saharan markets. This finding must be taken into consideration in food security strategies in sub-Saharan Africa.

To address sustainability challenges of agro-ecosystems located in Mediterranean urban regions, this paper focuses on the multidisciplinary subject of urban agricultural systems. To better understand the diversity and dynamics of peri-urban agro-ecosystems and the main drivers of their sustainability, we compare six case studies located in Southern Europe (Montpellier, France; Pisa, Italy; Lisbon, Portugal; Athens, Greece) and the Maghreb (Constantine, Algeria; Meknes, Morocco). The research is based on fieldwork in each urban region (qualitative analysis) and literature analysis aimed to position each case study in its national and Mediterranean contexts. The comparison between local contexts indicates large discrepancies in the integration of environmental focus among the respective urban planning objectives. Generally, urbanization tends to accentuate agricultural diversity. The different forms of peri-urban agriculture evolve despite their persistent decline, and they also show a capacity to resist and even new growth in response to urban demand.

The International Year of Quinoa (IYQ) in 2013 celebrates this Andean plant for its potential contribution to the fight against hunger and poverty. The development of this sector can also have a territorial impact, depending on the context and on the accompanying process, as shown by the comparison between the Salars region in the south of the Bolivian Altiplano, the Central Chile region and the Mapuche region in southern Chile.

Over the last few decades, local governments have become increasingly powerful political actors. The disengagement of States, food crises and the concentration of people in cities—exacerbating the current food system's harmful effects on sustainable development—have led cities to develop their own food policies. While these issues are not new, there has up to now been little discussion of the perspective of local authorities in urban areas and how they can help address the issues, especially in Africa, Latin America and Asia. The response of the UNESCO Chair on World Food Systems of Montpellier SupAgro and CIRAD was to organize the international Urban Food Policies meeting, held in Montpellier from 16 to 18 November 2015. By giving a voice to the representatives of cities and regions, the UNESCO Chair on World Food Systems of Montpellier SupAgro, CIRAD and their partners have helped to show not only that cities have the leverage they need to make a contribution, alongside national policies and international agreements, to food security and the sustainability of food systems, but also that the cities of the global South are often at the leading edge of these developments. This book contains the proceedings of the international meeting.
