Climate change models for Sri Lanka suggest that profound and complex changes in rainfall patterns are becoming a reality.. It’s never too early to consider what this means and how it could impact agriculture and therefore all of us.
The news that climate change will affect Sri Lanka’s weather will surprise very few these days. However, a recent study1 projecting rainfall distribution patterns in Sri Lanka for 2050 warns that climatic zones could shift. It also suggests that the intensity of rainfall will vary more greatly than observed over recent times. The findings reported by Muththuwatta and Liyanage, have important implications for agriculture – from farmers to policymakers.
With global temperatures warming over the past century, Sri Lanka has already displayed its share of signs of climate change. The resulting extreme weather events have even now affected agricultural production. Concerns for water and food security for a projected global population of 9.6 billion in 2050 are high. In its 2007 assessment report, the Intergovernmental Panel on Climate Change (IPCC) stated that the nature of changes will vary across different geographical regions and development statuses. It added that the way regions respond and adapt will also affect climate change.
