This study examined the determinants of adoption of improved soybean seeds among farmers in southern Borno State, Nigeria. Data for the study were obtained from 360 respondents selected through multi-stage sampling procedure. Inferential statistical techniques namely the Logit model and the Tobit model were used to estimate the likelihood of technology adoption among respondents and the extent of adoption of improved soybean seeds by the respondents, respectively. Yield of soybean and distance to source of improved seeds were statistically significant factors (ρ ≤ 0.01) that influenced the likelihood of adoption of improved soybean seeds among the respondents. Farm size and distance of respondents to source of improved soybean seeds were statistically significant factors (ρ ≤ 0.01) that influenced the extent of adoption of improved soybean seeds among the respondents. Based on the findings of this study, it is recommended that improved technologies in the form of high yielding seeds varieties should be made available to farmers. Farm service centers should be established within reasonable distance from farming communities. This is the bring technologies closer to farmers, thereby reducing the risks that farmers have to encounter to get farm inputs.
Men and women farmers experience different impacts of climate variability and change (CVC). Research on the differentiated impacts of variability and change in rainfall on gender is limited in the study area. This study examined perceptions and experience of men and women farmers on the impacts of CVC, using climate data and farmers' perception from a gender perspective. It examined the effect of CVC on annual and seasonal rainfall, number of rain days, onset and cessation of rainfall; perceived impacts of CVC on annual and seasonal rainfall and compared the measured (meteorological) impacts with the perceived impacts across gender. Mixed methods of qualitative and quantitative data collection and participatory rural approaches were used. Household survey of 50% men and 50% women each were conducted in six farming communities. Data analysis involved the use of annual rainfall trends, Annual Rainfall Anomaly (ARA), Standardized Annual Rainfall Anomaly (SARA), regression analysis percentages and chi-square. Results reveal the occurrences of more dry years than wet years (ARA and SARA <0.00) in the three locations. There were wide variability and changes in inter-annual rainfall in Ogbaru (R 2 = 0.0003), Anambra East (R 2 = 0.0071) and Ayamelum (R 2 = 0.0014). Seasonal rainfall was unevenly distributed from 2007-2016. There were wide variations in dates of onset and cessation of rainy season (R 2 = 0.006) and number of rain days (R 2 = 0.009). Men and women responses revealed that there were statistically significant (p < 0.005) changes in the onset of rainy season, early cessation of annual rainfall; alteration of growing seasons; frequent flooding and frequent drought. Women felt more impact of food insecurity, water shortage and had more burden of migration due to changes in rainfall. This study concludes that respondents perceived and experienced impacts of CVC which varied across gender. Hence, it recommends the provision of sustainable water and irrigation system which should encourage women's participation in the construction, maintenance and management among others.
The agricultural sector which contributes between 20-50% of gross domestic product in Africa and employs about 60% of the population is greatly affected by climate change impacts. Agricultural productivity and food prices are expected to rise due to this impact thereby worsening the food insecurity and poor nutritional health conditions in the continent. Incidentally, the capacity in the continent to adapt is very low. Addressing these challenges will therefore require a holistic and integrated adaptation framework hence this study. A total of 360 respondents selected through a multi-stage random sampling technique participated in the study that took place in Southern Nigeria from 2008-2011. Results showed that majority of respondents (84%) were aware that some climate change characteristics such as uncertainties at the onset of farming season, extreme weather events including flooding and droughts, pests, diseases, weed infestation, and land degradation have all been on the increase. The most significant effects of climate change that manifested in the area were declining soil fertility and weed infestation. Some of the adaptation strategies adopted by farmers include increased weeding, changing the timing of farm operations, and processing of crops to reduce post-harvest losses. Although majority of respondents were aware of government policies aimed at protecting the environment, most of them agreed that these policies were not being effectively implemented. A mutually inclusive framework comprising of both indigenous and modern techniques, processes, practices and technologies was then developed from the study in order to guide farmers in adapting to climate change effects/impacts.
Climate change is perhaps the most serious environmental threat to the fight against hunger, malnutrition, disease and poverty in Africa, essentially because of its impact on agricultural productivity. The objective of this paper was to identify the major barriers to climate change adaptation among smallholder farmers of Southern Nigeria. The paper was based on primary data collected within the framework of the Development Partnership for Higher Education (DelPHE) Project from 360 farming households selected randomly from the region. The data was analyzed using descriptive statistics and factor analysis. The result of the analysis show that majority of the farmers were men (70%), relatively educated (average of 9 years in school) and practiced mixed farming (61%). The major factors constraining farmers from adapting to climate change impacts were-(a) land constraints which manifested itself in limited availability, high costs and poor ownership systems (tenure); (b) poor climate change information and agricultural extension service delivery; (c) high cost of farm inputs and processing facilities; (d) high cost of irrigation facilities and government irresponsiveness to climate change risk management, (e) credit constraints, (f) labour constraints, and (g) income constraints. The paper concludes with a recommendation that farmers need to be supported in order for them to effectively adapt to the climate change impacts that are already affecting their production and hence reduce hunger and poverty. These supports could come from governments, non-governmental organizations and even farmers' unions themselves.
