Water Management Technology for Adaptation to Climate Change in Rice Production: Evidence of Smart-Valley Approach in West Africa
Low productivity is the main characteristic of agriculture in sub-Saharan Africa. Adverse effects of climate change increasingly reduce both productivity and production. Rice plays an important role in the food security of population. However, rice production faces many constraints, including low water control and soil fertility management. In order to improve water control and soil management and increase the productivity of local rice production in the context of climate change, a new technology (smart-valley approach) was introduced in Benin and Togo since 2010. The aim of this study is to assess the adoption, the diffusion and impact of smart-valley approach. Data were collected from 590 rice farming households in Benin and Togo. Results revealed that land tenure, total available area, paddy price and production in the lowland increase the adoption of smart-valley approach. Adoption of smart-valley approach increased from 110 ha in 2012 to 474 ha in 2014. In addition, the adoption enables producers to increase the yield by 0.9 tons ha−1, the net income by USD 267 per hectare under the condition of climate change. The study suggests that large diffusion and training on the technology would help for adaptation to climate change and improving their livelihood of smallholder rice farmers.
