“…The prime reason put forward for this discrepancy in maize yields between SSA and other regions is less adaptive capacity of smallholder farmers to climatic change-related effects. Ng'ombe et al [25] suggest the success of agriculture in SSA is hindered by the negative effects of climate change while [6] contend that less adaptive capacity of smallholder farmers in SSA coupled with their rain-fed farming systems (common in SSA) expose their vulnerability to climatic effects while. This observation corroborates [24] who suggest that the large gap in yield between countries in SSA and countries with comparable production conditions is larger when rain-fed areas are considered.…”

“…Mulungu et al [31] show that for maize in Zambia under the worst-case scenario, maize yields will decrease by 25% driven mainly temperature increases offsetting the gains from increased rainfall. Hamududu and Ngoma [6] suggest decline in water availability in Zambia by 13% by the end of the century in 2100 at national level as a result of climate change which poses a much greater risk to field crops such as maize.…”

“…Africa's inability to cope with the physical, human and socioeconomic consequences of the extremes of climate makes it the most susceptible to climate change [1,6,7,10,23]. What also adds weight to the incumbent problem is that majority of maize agricultural producers in SSA reside in rural areas.…”

“…For example, IPCC [4] suggest that rising temperatures and changing precipitation rates will most likely hamper success of rain-fed agriculture in most developing countries. Africa is one of the continents that is projected to experience rising temperatures of at least 1 to 2°C and higher likelihood of extreme weather [5,6]. Thus, the effects of climate change will more directly affect agriculture because about three-quarters of Africa's population depends on agriculture for a livelihood and Africa's agriculture is mainly rain-fed [7][8][9][10][11].…”

Maize - Production and Use

View full text Add to dashboard Cite

Maize (Zea mays L.) is one of the commonly grown grain crops and remains a source of staple food and food security for most countries in sub-Saharan Africa (SSA). But climate change threatens agricultural potential in SSA thereby risking food security especially that most maize production is rain-fed in these countries. Thus, numerous studies have examined impacts of climate change on maize production and productivity resulting in several adaption strategies being promoted to mitigate the negative effects of climate change. But to the best of our knowledge, there has not been any studies in literature that provide a review of impacts of climate change on maize production and productivity in SSA. This chapter therefore provides a review of empirical climate change impacts on maize production and its productivity in SSA. We chose SSA because most countries in SSA are underdeveloped and therefore more vulnerable to climate change effects. This is important because this review will provide an easier access of such results for both scholars and policy makers in search of empirical impacts of climate change on maize production and productivity in SSA.

“Are They Aware, and Why?” Bayesian Analysis of Predictors of Smallholder Farmers’ Awareness of Climate Change and Its Risks to Agriculture

While climate change threatens global food security, health, and nutrition outcomes, Africa is more vulnerable because its economies largely depend on rain-fed agriculture. Thus, there is need for agricultural producers in Africa to employ robust adaptive measures that withstand the risks of climate change. However, the success of adaptation measures to climate change primarily depends on the communities’ knowledge or awareness of climate change and its risks. Nonetheless, existing empirical research is still limited to illuminate farmers’ awareness of the climate change problem. This study employs a Bayesian hierarchical logistic model, estimated using Hamiltonian Monte Carlo (HMC) methods, to empirically determine drivers of smallholder farmers’ awareness of climate change and its risks to agriculture in Zambia. The results suggest that on average, 77% of farmers in Zambia are aware of climate change and its risks to agriculture. We find socio-demographics, climate change information sources, climate change adaptive factors, and climate change impact-related shocks as predictors of the expression of climate change awareness. We suggest that farmers should be given all the necessary information about climate change and its risks to agriculture. Most importantly, the drivers identified can assist policymakers to provide the effective extension and advisory services that would enhance the understanding of climate change among farmers in synergy with appropriate farm-level climate-smart agricultural practices.

Climate change impacts on maize and soybean yields in Zambia

Projected changes in temperature and rainfall directly threaten the overall agricultural crop production system in Zambia where 75% of agricultural production is rainfed. This study investigates the effects of future climate on maize (Zea mays L.) and soybean [Glycine max (L.) Merr.] yields using relatively high spatial resolution downscaled climate data in Central and Eastern Zambia. The Agrometshell model was applied to simulate historical and future crop yields. To account for the effects of climate change on crop yields, global climate models (GCMs) and Representative Concentration Pathways (RCPs) were used. Most yield functions were significant with R2 values >.7 with p < .05, indicating the model's ability to capture variations in observed data. Mean maize yield change decreased across RCPs and GCMs in Central Province and the decrease amplified in several areas in the far future, suggesting worsening effects into the future. But the projected mean yield changes in Eastern Province remain mostly within the historical range of variability, suggesting that maize yield in this province is less sensitive to climate change. Projected mean soybean yield changes in Central Province consist of a combination of reductions and improvements. Soybean yields in Eastern Province were projected to increase in the near future, shifting to large increases in the far future. Drastic reductions in maize yields are likely to cause major negative effects in the agricultural system because maize is a staple crop in the country. In contrast, soybean showed less sensitivity to future climate and demonstrates the value of diversifying agricultural systems and increasing the sustainability of food production systems.
