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.







Handbook of Climate Change Adaptation


Book Description

The Handbook of Climate Change Adaptation addresses the scientific, social, political and cultural aspects of climate change in an integrated and coherent way. The multi-volume reference focuses on one of the key aspects of climate change: adaptation and how to handle its impacts on physical, biotic and human systems, analyzing the social and normative scientific concerns and presenting the tools, approaches and methods aimed at management of climate change impacts. The high-quality, interdisciplinary contributions provides state-of-the-art descriptions of the topics at hand with the collective aim of offering, for a broad readership, an authoritative, balanced and accessible presentation of the best current understanding of the nature and challenges posed by climate change. It serves not only as a valuable information source but also as a tool to support teaching and research and as help for professionals to assist in decision-making.




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.







South Asia's Hotspots


Book Description

South Asia is particularly vulnerable to climate change. Most previous studies have focused on the projected impacts of sea-level rise or extreme weather - droughts, floods, heatwaves and storm surges. This study adds to that knowledge by identifying the impacts of long-term changes in the climate †“ rising temperatures and changes in precipitation patterns †“ on living standards. It does so by first building an understanding of the relationship between current climate conditions and living standards across South Asia. The study also identifies the set of climate models that are best suited for projecting long-term changes in climate across South Asia. This novel understanding of living standards and climate change is then combined to project impacts of long-term changes in climate on living standards in South Asia. The study finds that higher temperatures will reduce living standards for most of South Asia, with the severity impacts depending on future global greenhouse gas emissions. The study projects “hotspots†?, which are locations where long-term changes in climate will have negative impacts on living standards. Many hotspots are in locations that hitherto have not been identified as particularly vulnerable to climate change. Moreover, hotspots have distinguishing features that vary from country to country. This detailed assessment provides a mosaic of information that enriches our understanding of how climate change will impact people and which populations are most vulnerable. The report also provides guidance on the kinds of actions are most likely to reduce impacts of climate change in each country. The study is a major contribution to our understanding of how increasing temperatures and changing precipitation patterns interact with social and economic structures at a fine granular level across South Asia.

Climate Change and Food Security in South Asia


Book Description

This book addresses an important topic of food security in South Asia with specific reference to climate change. Of the 1 billion food insecure people in the world, more than 30% are in South Asia. The problem of food insecurity may be exacerbated by the projected climate change especially because of the water scarcity caused by rapid melting of the glaciers in the Himalayas and increase in variability in monsoonal rains and frequency of extreme events. Furthermore, large populations of Bangladesh and other coastal regions may be displaced by sea level rise. Thus, this volume addresses recommended land use and soil/water/crop/vegetation management practices which would enable land managers to adapt to climate disruption by enhancing soil/ecosystem/social resilience. In addition to biophysical factors, this book also addresses the issues related to human dimensions including social, ethnical and political considerations.




A Ricardian Analysis of the Impact of Climate Change on African Cropland


Book Description

This study examines the impact of climate change on cropland in Africa. It is based on a survey of more than 9,000 farmers in 11 countries: Burkina Faso, Cameroon, Egypt, Ethiopia, Ghana, Kenya, Niger, Senegal, South Africa, Zambia, and Zimbabwe. The study uses a Ricardian cross-sectional approach in which net revenue is regressed on climate, water flow, soil, and economic variables. The results show that net revenues fall as precipitation falls or as temperatures warm across all the surveyed farms. In addition to examining all farms together, the study examined dryland and irrigated farms separately. Dryland farms are especially climate sensitive. Irrigated farms have a positive immediate response to warming because they are located in relatively cool parts of Africa. The study also examined some simple climate scenarios to see how Africa would respond to climate change. These uniform scenarios assume that only one aspect of climate changes and the change is uniform across all of Africa. In addition, the study examined three climate change scenarios from Atmospheric Oceanic General Circulation Models. These scenarios predicted changes in climate in each country over time. Not all countries are equally vulnerable to climate change. First, the climate scenarios predict different temperature and precipitation changes in each country. Second, it is also important whether a country is already hot and dry. Third, the extent to which farms are irrigated is also important.
