Small-scale fisheries play a significant role in enhancing livelihoods, creating employment and contributing to food security especially in developing countries. Rural fishing communities are highly dependent on natural resources, which are climate sensitive. Many research efforts have been made to understand the impacts of climate change on fisheries and fishing economies. However, little attention has been given to understand the challenges experienced by small-scale fishing communities in developing countries in Africa. This article assesses non-climate change and climate change-induced challenges according to the experiences of the gillnet small-scale fishers of Sanyathi fishing basin of Lake Kariba, Zimbabwe. The study used a qualitative research design, and data were collected using semi-structured in-depth interviews with fishers. Thematic content analysis was used to analyse interview transcripts. The study results showed that declining fish catches is one of the major challenges experienced by fishers. The main themes that emanated as the challenges faced by fishers are food insecurity, wildlife attacks, lack of access to information systems, lack of fishing equipment, the existence of the predator crayfish, poor lake co-management and shrinking fishing boundaries. Overall, the study found that fish production is negatively affected by several political, economic and environmental factors; therefore, development through the public and private organisations should incorporate small-scale fishers in policy formulation to positively enhance livelihoods and food security.

Drought is a major challenge threatening agricultural productivity in uMsinga. The occurrence of drought is expected to increase in coming decades, intensifying in severity, duration and the way people are affected by drought. The objective of this study is to understand small-scale farmers' and rural communities' perceptions of drought, its environmental and socio-economic impacts, adaptive and mitigation measures at household level and their satisfaction with the government's role in drought management in the community. The study utilized a combination of quantitative and qualitative research methods, in the form of questionnaires, focus groups and key informant interviews. The sample size for the research study was 180 respondents for the questionnaire component and a total of 30 respondents for the focus groups and key informant interviews. The results show that increased levels of poverty, food insecurity and increased migration were the main socio-economic impacts perceived by respondents. Water scarcity, crop failure, forest degradation and an increase in average temperatures were perceived by respondents as the main environmental impacts caused by drought in uMsinga. Respondents perceived drought as a serious threat to agricultural production and adopted various indigenous adaptive strategies. A majority of respondents adopted a reactive approach to drought management, and therefore did not adopt many mitigation measures.

AbstractIndigenous knowledge has for generations assisted rural subsistence farming communities adapt to climate change and make daily decisions regarding agriculture. This study was conducted in the rural community of Swayimane, uMshwathi Municipality, KwaZulu-Natal, South Africa. The main objective of the research was to determine the indigenous indicators used by rural farmers, identify the means through which seasonal climate information is disseminated and assess the strengths and weaknesses of indigenous and scientific knowledge. The other objective of the research was to evaluate the integration of indigenous and scientific weather forecasting. The research used 100 questionnaires which were administered to the subsistence farmers of the community. Focus group discussions and key informant interviews were conducted with small groups of individuals. Results showed that majority of the indigenous indicators related to rainfall and seasonal predictions. Also, seasonal scientific climate information was mainly disseminated via television and radio. Local farmers highlighted that indigenous knowledge was essential in predicting seasonal changes and rainfall and scientific knowledge was not trusted. Indigenous knowledge is transmitted by oral tradition, from generation to generation and mainly among the elderly, and, thinly, to the younger generation. Scientific information was thought to be too technical and difficult to comprehend. It can be concluded that subsistence farmers were open to the integration of scientific and indigenous weather forecasting. They highlighted that it would improve decision making concerning their agricultural activities.

AbstractSmallholder agricultural production is largely affected by climate change and variability. Despite the negative effects brought by climate variability, smallholder farmers are still able to derive livelihoods. An understanding of factors that influence farmers' responses and adaptation to climate variability can improve decision making for governments and development partners. This study investigated farmers' perceptions and adaptation strategies to climate change and how these influence adaptation policies at local level. A survey was conducted with 100 households randomly selected from Chiredzi district. Data collected was used to derive farmer perceptions to climate change as well as the influence of their perceptions and subsequent adaptation methods to ensuing local agricultural adaptation measures and policies. The results indicated that smallholder farmers perceived general reduction in long-term annual rainfall and rising local average temperatures. Adverse trends in rainfall and average temperature perceived by farmers were consistent with empirical data. These perceptions and other socio-economic factors helped to shape smallholder farmer agricultural adaptation strategies. Policy implications are that the government and development partners should seek ways to assist autonomous adaptations by farmers through investments in planned adaptation initiatives.

Small-scale fisheries play a significant role as a source of employment, livelihood strategy and contributor to food security. However, changes in climatic variables alter the productivity and distribution of marine and freshwater fish species, negatively affecting the livelihoods of fishery-dependent communities. This study seeks to identify small-scale fishers' livelihoods and examine the impacts of climate change on livelihoods and food security of small-scale fishing households. The study was conducted in Sanyathi fishing basin in Lake Kariba, Zimbabwe. The Sustainable Livelihood Approach framework of the Department for International Development was used to define the small-scale fishers' livelihood assets and activities. The study employed a mixed-method approach for data collection. A pretested, semi-structured questionnaire, focus group discussions and observations were used to collect data from the small-scale fishers. The data collected were subjected to descriptive and bivariate analysis. The present results indicate that fishing is the community's primary livelihood activity. More than 62% of fishermen stated that fishing revenue is declining, owing to declining fish catches. Of participants, 98% recognised food purchases as the primary source of food. Therefore, 78% of the small-scale fishers perceive their households to be food insecure due to declining incomes from fisheries. These findings show the need for policymakers and development agencies to formulate strategies that specifically target fishing communities whose livelihoods rely on natural ecosystems.

Abstract
The monoculture vegetable production systems practiced by Zimbabwean farmers has resulted in major disease outbreaks, causing major production constraints. There is need to determine the intensity of pesticides usage and methods of alternative disease management strategies. This study was carried out using 250 randomly selected vegetable farmers by administering questionnaires. The study objectives were to determine farmers' perceptions on vegetable disease incidence and severity in relation to prevailing weather conditions, and determine common control methods practiced to manage fungal and bacterial disease outbreaks. The results indicated significant increases in fungal and bacterial disease incidence of 84.6% (within community cropping fields) and severity of 73.1% (within individual farmer fields) over the past 5-10 years (P £ 0.05). It also revealed disease incidence being highest [30.8%] during winter (May – July) and rainy months [23.1%] (November – February). Results further indicated 96.2% of the respondents relied on chemical methods, 53.8% used cultural control, and 11.5% used natural control methods. However, none of the farmers used bio-pesticide/biological control methods. In conclusion: farmers are aware of the disease shifts in response to different climate variability but seem unaware of the negative effects of extensive chemical use, nor existence of alternative bio-pesticide/biological disease management strategies.

This study assessed the provision of informal training offered by the Limpopo Department of Agriculture, South Africa, to agricultural extension officers (AEOs). The study used surveyed 90 public extension officers purposively sampled. There were statistically significant differences in extension officers' exposure to climate change between their education levels and in the provision of climate change training between extension officers' work experience ( P⩽0.05). The study concluded that the majority of AEOs have not been fully exposed to climate information prior to their employment. This suggests that the information gap in Agricultural Extension and Advisory Services (AEAS) stems from the slow mainstreaming and integration of climate change information.

AbstractThis study investigated the perceived effects of climate change on crop production and household livelihoods of smallholder farmers in Mopani and Vhembe district, South Africa. Data was collected through a questionnaire administered to 150 smallholder farmers. The questionnaires were complemented by 8 focus group discussions and secondary data. Multinomial logit regression model was used to analyse the factors influencing smallholder farmers' choice of climate change adaptation strategies. The study findings revealed that subsistence farmers perceived prolonged droughts (56.4%) as the main shock stressing crop production. Droughts often lead to low crop yield and high crop failure (73.3%). In response to the prevailing climatic conditions different gender adopted different strategies, 41% of female farmers adapted by changing planting dates, while male farmers employed crop variety and diversification (35%) and mixed cropping (15%). The smallholder farmers were vulnerable with limited adaptive capacity to withstand climate change due to compromised social, human, physical, natural and financial assets. The results showed that smallholder farmers tend to adapt better when they have access to extension officers (P<0.01). Therefore, it is important for the government to strengthen the relationship between smallholder farmers and extension officers for better climate change adaptation.

This study examined gaps in climate information within public agricultural extension in Limpopo Province, South Africa. It assessed extension officers' climate change perceptions, knowledge and climate education. Lastly, the study examined the extension approaches for overall suitability of climate information disseminated to rural smallholder farmers. The results indicated that participants were predominately male, with tertiary education. Education levels had an influence on exposure to climate education and extension approaches in disseminating agricultural information to farmers. There is a need to retool extension officers in climate change extension work, integrating indigenous knowledge to increase suitability and acceptability of information by smallholder farmers.
