Abstract
This article assesses the consequential risk impacts of the recent system of rice intensi cation (SRI) implemented in the Morogoro region of Tanzania, one of the largest Semi-Arid regions, using household and farm plot level data extended to incorporate farmers' perceptions of climate change. The analysis implements a moment approximation approach that accounts for the impacts of the technology on the first three moments of rice yields and total household income. Using a endogenous switching regressions model, we nd that perception of climate change is a key driver for SRI adoption and impacts primarily the moments of income. Thereby, the study highlights the importance of climate perceptions and moisture-conserving technology in risk management in Semi-Arid areas. The theme of the study also falls within the objectives of PRISE (Pathways to Resilience in Semi-Arid Economies) as it brings together institutional intervention (in the form of SRI provision), land productivity and vulnerabilit y (in the form of farmers' perceptions of climatic factors).
Description
The research for this paper was carried out as part of the PRISE project, under the Collaborative Adaptation Research Initiative in Africa and Asia (CARIAA), with financial support from the UK Government’s Department for International Development (DfID) and the International Development Research Centre (IDRC), Canada.
