Drought is a noteworthy cause of low agricultural profitability and of crop production vulnerability, yet in numerous countries of Africa little to no consideration has been paid to readiness for drought calamity, particularly to spatial evaluation and indicators of drought occurrence. In this study, biophysical and socio-economic data, farmers’ community surveys and secondary data from remote sensing on soil characteristics and water demand were used to evaluate the predictors of drought in inland valley rice-based production systems and the factors affecting farmers’ mitigation measures.

Estimating the potential land resources suitable for irrigation and evaluating the possible impact of climate change on land suitability is essential for planning a sustainable agricultural system. This study applied a GIS-based Multi-Criteria Evaluation (MCE) technique to evaluate the suitability of land for irrigation in Ghana for a baseline period (1990 to 2010) and future time horizons 2050s (2041 to 2060) and 2070s (2061 to 2080).

Our goal is to provide the scientific basis for development investments and policies that promote more productive, profitable agriculture, and healthier diets at no environmental cost. Low-income, smallholder farmers face significant challenges across sub-Saharan Africa (SSA). High population growth is coinciding with migration to the cities as younger populations seek out higher income-earning opportunities. Inadequate infrastructure and few markets for agricultural production in rural areas, for example, are leading to stagnated opportunities for smallholders.
