Small Tanks in Sri Lanka


Book Description

The core of this study involved an examination and analysis of certain key features of the traditional small tank cascade systems: a) the location and design of the systems in the past b) the hydro-system which considers the overall hydrological balance and groundwater conditions c) maintenance and tank use d) tank management and integration with local farming systems.







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.




Water management in rural South India and Sri Lanka


Book Description

Water resources and their uses and management are - worldwide and on the regional scale of South Asia - one of the main concerns of the environmental and social equilibrium of the new century. These proceedings therefore contribute to the efforts of Indo-French and Sri Lankan-French cooperation to develop scientific collaboration on water management. The contributions by Indian, Sri Lankan and French specialists in the social sciences – historians, economists, sociologists, anthropologists, geographers – as well as specialists in agronomy, soil sciences or forestry, offer critical approaches and data from various disciplines regarding the understanding of water availability and water uses and management in South India and Sri Lanka, along with themes that emerge from these considerations.







Impacts of climate change on water resources and agriculture in Sri Lanka: a review and preliminary vulnerability mapping.


Book Description

There is ample evidence to suggest that Sri Lanka’s climate has already changed. However, the bigger question of national importance is what Sri Lanka’s climate will look like in 50 or 100 years and how prepared the country is to face such changes. This report reviews the status of climate change (CC) research/activities in Sri Lanka in terms of observed and projected climatic changes, their impacts on water resources and agriculture, CC mitigation and adaptation, and research needs. The study also developed a pilot level CC Vulnerability Index, which was subsequently mapped at district level. The maps indicate that typical farming districts such as Nuwara Eliya, Badulla, Moneragala, Ratnapura and Anuradhapura are the most vulnerable to CC due to their heavy reliance on primary agriculture.




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.
