“…Finally, rainfall was associated with maize, rice, or cassava yields in any state. Many other studies have reported the similar finding of the climate-crops relationships in China (Zhang et al 2016;Gao et al 2019;Ding et al 2020), Southern Africa (Mafongoya et al 2017;Nhamo et al 2019) and East African countries (Sridharan et al 2019;Thomas et al 2019). These results dovetail with results from previous research.…”

This chapter examines the impacts of climate change on three tropical crops and assesses the climate change adaptation options adopted by rural farmers in the region. The study was conducted among farming communities settled in three major ecological zones in Nigeria. Over 37 years of data on rainfall and temperature were analyzed to examine climate change impacts on three major crops: rice, maize, and cassava. Farmers’ adaptive capacity was assessed with a survey. Climatic data, crop yields, and survey data were analyzed using both descriptive and inferential statistics. The relation between rainfall/temperature and crop yields was examined using the Pearson correlation coefficient. Results show a high variation in the annual rainfall and temperature during the study period. The major findings from this research is that crops in different ecological zones respond differently to climate variation. The result revealed that there is a very strong relationship between precipitation and the yield of rice and cassava at p <0.05 level of significance. The results further showed low level of adaption among the rural farmers. The study concludes that rainfall and temperature variability has a significant impact on crop yield in the study area, but that the adaptive capacity of most farmers to these impacts is low. There is a need for enhancing the adaptation options available to farmers in the region, which should be the focus of government policies.

“…Risks of global climate change exacerbate natural resource and related constraints on livestock production (16) (17). For example, climate projections for Southern Africa to 2050 indicate the coverage of arid regions expanding, while sub-humid zones shrink towards the equator (18). Crop and livestock production systems in the region could see major shifts in response to the climate-induced changes (19).…”

“…Crop and livestock production systems in the region could see major shifts in response to the climate-induced changes (19). Being dependent on seasonal rainfall distributions and rainfall amounts, Africa's smallholder cropping systems may be particularly vulnerable to increased variability in crop cover and crop yields (18). Livestock producers in dry and marginal areas are in addition vulnerable to climate effects on animal performance; water availability for household, agricultural and other use; and the quantity and quality of feeds (19).…”

The demand for livestock-derived foods has steadily grown over the past decades and rising incomes and human populations are expected to see demand further increase. It is unclear if current livestock feed resources are adequately prepared to meet future demand especially given the looming challenges of climate change. Many feeds such as grasses, crop by-products, and other biomass may not be widely grown commercially or sold in formal markets but are critical sources of livestock feed in many low-resource settings in which ruminant livestock production is important. The availability of these feed types can determine the extent to which the livestock sector can expand to meet growing, and sometimes critical, demand for animal-source foods. In this paper, we compare country-level projections of livestock demand from a global economic model to simulated data on feed biomass production. Our comparisons account separately for beef, lamb, and dairy demand. The data allow us to assess the future sufficiency of key sources of feed biomass, and hence aspects of the expansion capacity of livestock production in selected countries in Southern Africa. Our simulation results project that given the interacting effects of projected climate change and changes in income and population in the region, there will not be enough feed biomass produced domestically to meet growing demand for livestock products. For three types of feed biomass (feed crops including grains, grasses, and crop by-products) for which future livestock feed sufficiency was examined, our results showed feed sufficiency declines for all three feed types in Malawi and Mozambique, for two out of three in South Africa and for one of three in Zambia, under intermediate and extreme scenarios of climate change in 2050. Our results suggest an urgent need to improve feed biomass productivity to support future supply of animal protein in the study countries.
