<p>The study examines how farmers’ observations of climate variability and change correspond with 42 years (1970-2011) meteorological data of temperature and rainfall. It shows how farmers in the Northern Region of Ghana adjust to the changing climate and explore the various obstacles that hinder the implementation of their adaptation strategies. With the help of an extension officer, 200 farmers from 20 communities were randomly selected based on their farming records. Temperatures over the last four decades (1970-2009) increased at a rate of 0.04 (± 0.41) ˚C and 0.3(± 0.13)˚C from 2010-2011 which is consistent to the farmers (82.5%) observations. Rainfall within the districts are characterised by inter-annual and monthly variability. It experienced an increased rate of 0.66 (± 8.30) mm from 1970-2009, which was inconsistent with the farmers (81.5%) observation. It however decreased from 2010-2011 at a huge rate of -22.49 (±15.90) mm which probably was the reason majority of the respondents claim rainfall was decreasing. Only 64.5% of the respondents had adjusted their farming activities because of climate variability and change. They apply fertilizers and pesticides, practice soil and water conservation, and irrigation for communities close to dams. Respondents desire to continue their current adaptation methods but may in the future consider changing crop variety, water-harvesting techniques, change crop production to livestock keeping, and possibly migrate to urban centers. Lack of climate change education, low access to credit and agricultural inputs are some militating factors crippling the farmers’ effort to adapt to climate change.</p>

SUMMARYThis study examines farmers’ perceptions of short- and long-term variability in climate, their ability to discern trends in climate and how the perceived trends converge with actual weather observations in five districts of Eastern Province in Kenya where the climate is semi-arid with high intra- and inter-annual variability in rainfall. Field surveys to elicit farmers’ perceptions about climate variability and change were conducted in Machakos, Makueni, Kitui, Mwingi and Mutomo districts. Long-term rainfall records from five meteorological stations within a 10 km radius from the survey locations were obtained from the Kenya Meteorological Department and were analysed to compare with farmers’ observations. Farmers’ responses indicate that they are well aware of the general climate in their location, its variability, the probabilistic nature of the variability and the impacts of this variability on crop production. However, their ability to synthesize the knowledge they have gained from their observations and discern long-term trends in the probabilistic distribution of seasonal conditions is more subjective, mainly due to the compounding interactions between climate and other factors such as soil fertility, soil water and land use change that determine the climate's overall influence on crop productivity. There is a general tendency among the farmers to give greater weight to negative impacts leading to higher risk perception. In relation to long-term changes in the climate, farmer observations in our study that rainfall patterns are changing corroborated well with reported perceptions from other places across the African continent but were not supported by the observed trends in rainfall data from the five study locations. The main implication of our findings is the need to be aware of and account for the risk during the development and promotion of technologies involving significant investments by smallholder farmers and exercise caution in interpreting farmers’ perceptions about long-term climate variability and change.

The knowledge of exposure of croplands to climate variability is of paramount importance in adaptive capacity planning to boost food production for the world’s growing population. The study assessed the exposure of croplands to climate variability in the Federal Capital Territory (FCT) of Nigeria using Geo-informatics. This was achieved by examining the distribution pattern of climate indices in FCT from 1981-2017, determining the exposure index of croplands in FCT Area Councils and production of exposure map of FCT Area Councils, The spatial scope of this study is the entire arable land in FCT which is made up of six Area Councils. The research is contextually restricted to exposure of croplands to climate variables while other variables remain constant. The selected climatic variables are rainfall, temperature, relative humidity and potential evapotranspiration (exposure indicators). The arable crops in focus are yam, beans and maize while the soil variables selected for the study are: soil erosion, organic carbon content of the soil, clay content of the soil and percentage of arable land available for crop production. The temporal scope of the examined exposure indicators (climate variables) was limited to a period of thirty (37) years from 1981- 2017. The result indicates that Bwari has the highest exposure (0.1671) to climate variables while Abaji has the least (0.0868) exposure. AMAC is high (0.1371), Kuje (0.1304) is moderate while Gwagwalada (0.1132) and Kwali (0.1154) have low exposures to climate variability. The implication of this on the referenced crops is that crop yield will be highly reduced in Bwari and optimum in Abaji Area Councils due to their climatic requirement. The power of Geo-Spatial Technology in combining different indices of exposure to produce exposure map was demonstrated in the study.

Rice, the first crop to be fully sequenced and annotated in the mid-2000s, is an excellent model species for crop research due mainly to its relatively small genome and rich genetic diversity. The 130-million-year-old cereal came into the limelight in the 1960s when the semi-dwarfing gene sd-1, better known as the “green revolution” gene, resulted in the establishment of a high-yielding semi-dwarf variety IR8. Deemed as the miracle rice, IR8 saved millions of lives and revolutionized irrigated rice farming particularly in the tropics. The technology, however, spurred some unintended negative consequences, especially in prompting ubiquitous monoculture systems that increase agricultural vulnerability to extreme weather events and climate variability. One feasible way to incorporate resilience in modern rice varieties with narrow genetic backgrounds is by introgressing alleles from the germplasm of its weedy and wild relatives, or perhaps from the suitable underutilized species that harbor novel genes responsive to various biotic and abiotic stresses. This review reminisces the fascinating half-century journey of rice research and highlights the potential utilization of weedy rice and underutilized grains in modern breeding programs. Other possible alternatives to improve the sustainability of crop production systems in a changing climate are also discussed.

In post-conflict South Sudan, as in many other places, climate variability extreme events are already undermining communities’ livelihoods by causing adverse socioeconomic and environmental impacts. However, few studies have paid little attention to the extent to which climatic shocks have disturbed the community’s livelihood and resilience strategies built by communities. Quantitative methodological review using a systematic protocol to select scientific literature was employed. A total of twenty-five articles were extracted and analyzed. The findings indicated that climatic shocks such as flood, drought, have resulted in disruptive changes in cropping pattern, reduction in the crop production, erosion of social assets, exacerbate resource-based conflicts, resulting in large losses of livestock and disturbed the physical topography of the area leading to extinction of flora and fauna that constituted the livelihoods of the communities. Results also showed that: (1) crop farming and livestock rearing, (2) diversification of livelihood assets and, (3) switching to alternative off-farm businesses are pursued by households. This review paper recommends that policymakers should focus on building livelihood assets and investing in and outside the agriculture sector in order to promote sustainable livelihoods development and income diversification while providing pathways for communities to recover and adapt to climate variability.
