Minimizing irrigation water demand: An evaluation of shifting planting dates in Sri Lanka.

摘要: Climate change coupled with increasing demands for water necessitates an improved understanding of the water–food nexus at a scale local enough to inform farmer adaptations. Such assessments are particularly important nations significant small-scale farming and high spatial variability in climate, such as Sri Lanka. By comparing historical patterns irrigation requirements (IWRs) rice planting records, we estimate that shifting dates earlier season could yield savings up 6%. Our findings demonstrate potential low-cost adaptation strategies help meet crop production water-scarce environments. This local-scale assessment IWRs Lanka highlights value using data agricultural management resources when high-skilled forecasts not available. Given national policies prioritizing in-country farmers’ sensitivities stress, decision-makers should consider degrees climate institutional design structures.
