Climate change impacts on crops in Sri Lanka


Book Description

Agriculture is one of the most important economic sectors of Sri Lanka and is key to the livelihoodof its population. As agriculture is one of the sectors most vulnerable to climate change, a thorough understanding of its impact is critical for formulating informed and effective adaptation strategies. Climate change challenges agriculture in many ways and affects – directly or indirectly – the economy, productivity, employment and food security. Assessing the impacts of climate change on crops is fundamental for elaborating evidence-based adaptation policies and strategies, guaranteeing sustainable pathways towards intensification and adopting climate-smart agricultural practices. This report presents insights about future climate change impacts on six crops (rice, maize, green gram, big onion, chilli and potato), selected according to a wide range of criteria: contribution to gross domestic product, relevance to food security and role as staple food, importance for farming systems, social impact, effect on employment, role as animal feed, consumer preferences, contribution to the export market, climatic vulnerability/resilience, market prices and price fluctuations, and farming input requirements.




Dry zone of Sri Lanka – Climate-smart intensification of upland and lowland crop production systems


Book Description

This guide explores the climate-smart intensification of upland and lowland crop production systems in the dry-zone of Sri Lanka and provides technical guidance to achieve the productive objectives of selected strategic crops (as deemed relevant by the Government of Sri Lanka). The first edition focuses on maize and groundnut upland production systems and on rice lowland production. It provides a quick reference for information on crop production and soil management, including crop varieties, nutritional requirements and field equipment. As climate change will result in wider and more severe occurrences of plant pests, the guide relies on integrated pest management practices adapted to climate change. Optimizing the production of these crops calls for the diversification of crop systems using intercrops and cover crops. Additionally, sustainable mechanization is regarded as an essential agricultural production input to optimize labour and land productivity for the sustainable and profitable development of the agriculture sector. Therefore, the guide describes the innovative equipment needed for the sustainable optimization of crop production. To ensure coherent guidance and advice on sustainable farming practices, inputs and technologies, the guide has been developed in cooperation with all stakeholders working in the agriculture sector of Sri Lanka.
