“…Farmers in SSA countries are more likely to suffer due climatic shocks especially because of the unfavourable environment compounded by the fact that they sell their products as raw materials or with limited value addition (Terdoo and Feola, 2016b). They also lack the infrastructure that enhances resilience to climate weather shocks such as irrigation systems, early warning systems, hydrological systems and telecommunication facilities for information transfer.…”

The frequency, duration, and magnitude of extreme weather events such as droughts, floods, and variation in rainfall onset and cessation periods will continue to increase. Such stress may result in significant shifts in the functioning of ecosystems. As climate change affects the capacity of ecosystems to mitigate the effects of extreme events such as drought and floods, leading to disruptions in water supply and food production, or to the destruction of infrastructure, human well-being is ultimately impacted. Chief among those impacts are those on the four dimensions of food security: food availability, accessibility, utilization, and stability. An interesting channel of impacts is through the observed and forecasted increase in the variability of water availability. This is said to cause uncertainty in agricultural production resulting in reduced productivity, food insecurity, weak economic growth and the widespread food poverty in Africa today. Due to overreliance on rain-fed agriculture in Sub-Saharan Africa, people usually engage in both temporary and permanent migration after consecutive years of bad harvests and reduced incomes from agriculture with migration acting as an adaptation strategy to climatic shocks. Food value chains can be significantly affected, something that the paper identifies as an area that requires further research mainly on the resilience of food value chains to water variability.

“…This is to improve the sustainability of rice value chain (RVC), and also to curtail the market segmentation between imported and domestic rice products due to consumer preferences. Rice post-harvesting activities (especially processing) reduce the vulnerability of the RVC and improve its economic globalisation (Johnson, 2016;Terdoo, Feola, 2016). Lack of investment in rice post-harvest processing and inefficiencies in the market lower the capacity of RVC by increasing the marginalisation of the actors and exposing the industry to external shocks and climate change vulnerability.…”

“…Climate change affects rice value chain (RVC) right from production, to the extent that domestic supply capacity rarely meets demand in developing countries (van Oort et al, 2015). However, the effect of climate change on the processing node of rice value chain is largely neglected in literature.…”

The paper examined adaptation strategies used by rice processors in Ebonyi State to manage climate risks. The paper used random sampling technique to select respondents and questionnaire was used to collect data from the respondents. Cross-sectional data collected from 98 rice processors were analysed using descriptive statistics and multivariate probit regression model. The results indicated that majority of the rice processors perceived prolonged dry season and increased rainfall intensity as the main climate risks in the state. Livelihood diversification, storing of paddy, and reliance on climate information were the major adaptation strategies used by the rice processors to manage the climate risks. The main determinants of climate change adaptation strategies of rice processors were education, membership of cooperative societies, income, training on rice processing and climate risk management, experience of climate hazards, and ownership of assets. The processors faced various barriers to adoption which are mainly related to capital needs, competition from foreign brands, access to basic infrastructure and roads and information, high cost of labour. It is recommended that government support be given to the rice producing communities in terms of basic infrastructure and policies to protect the industry. Also, regular workshops/trainings should be held to train processors on best climate risk management practices and encourage registration of processor cooperatives/relevant associations.

Paddy-rice cultivation using the traditional continuous flooding method requires much water, up to 2500 L, to produce 1 kg of rice. Decreasing water availability is being exacerbated by climate dynamics, i.e., droughts and rainfall variability negatively affecting food security in developing regions, particularly Africa. Alternate wetting and drying (AWD) practice is a climate-smart water management strategy that, together with puddling (a critical field preparation process), significantly affects soil hydrological and physicochemical regimes, such as soil water dynamics and oxidation states in paddy fields. However, there are limited reviews on the effects and interaction of the AWD duration on hydrological conditions in the paddy-rice rhizosphere continuum under AWD practice at different rice growth stages. Our review synthesizes key scientific literature to examine water management and hydrological properties of paddy soils under AWD practice with climate change and sheds light on why farmers are skeptical in adopting the practice. To develop this paper, we reviewed scientific information from published journal articles, reliable reports, and our knowledge on paddy-rice cultivation and water management with climate change in Asia and Sub-Saharan Africa. Several studies confirm that AWD practice increases water–rice–crop productivity, yields, and reduces methane emissions. Limitations and challenges of AWD irrigation, including changes in soil structure that influence irrigation water application, variations in hydraulic conductivity caused by the duration and frequency of irrigation cycles, and frequent manual water level (WL) monitoring, are discussed. Opportunities to improve the integration of AWD strategies within government policies, irrigation schemes, and farmer acceptance due to skepticism, limited knowledge, and fear of unreliable water hindering adoption are highlighted. Future research suggestions include the following: (i) long-term measurement of water stress indices using infrared thermometers; (ii) seasonal suitability mapping using NDVI, GIS, and remote sensing; and (iii) application of smart sensors based on the Internet of Things (IoT) to address AWD challenges for precision water management in paddy fields with climate change.
