Climate change impacts on crops in Sri Lanka by Amarasingha, R., Marambe, B., Suriyagoda, L., Punyawardena, R., Herath, H., Jayawardena, S., Jayakody, P. et al. Pdf

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.

Impacts of climate change on water resources and agriculture in Sri Lanka: a review and preliminary vulnerability mapping. by Eriyagama, N.,Smakhtin, V.,Chandrapala, L.,Fernando, K. Pdf

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.

Crop Adaptation to Climate Change by Shyam Singh Yadav,Robert J. Redden,Jerry L. Hatfield,Hermann Lotze-Campen,Anthony E. Hall Pdf

A major task of our time is to ensure adequate food supplies for the world's current population (now nearing 7 billion) in a sustainable way while protecting the vital functions and biological diversity of the global environment. The task of providing for a growing population is likely to be even more difficult in view of actual and potential changes in climatic conditions due to global warming, and as the population continues to grow. Current projections suggest that the world's temperatures will rise 1.8-4.0 by 2100 and population may reach 8 billion by the year 2025 and some 9 billion by mid-century, after which it may stabilize. This book addresses these critical issues by presenting the science needed not only to understand climate change effects on crops but also to adapt current agricultural systems, particularly in regard to genetics, to the changing conditions. Crop Adaptation to Climate Change covers a spectrum of issues related to both crops and climatic conditions. The first two sections provide a foundation on the factors involved in climate stress, assessing current climate change by region and covering crop physiological responses to these changes. The third and final section contains chapters focused on specific crops and the current research to improve their genetic adaptation to climate change. Written by an international team of authors, Crop Adaptation to Climate Change is a timely look at the potentially serious consequences of climate change for our global food supply, and is an essential resource for academics, researchers and professionals in the fields of crop science, agronomy, plant physiology and molecular biology; crop consultants and breeders; as well as climate and food scientists.

Measuring the Impact of Climate Change on Indian Agriculture by Ariel Dinar Pdf

Using the Ricardian approach (a cross sectional analysis of farm performance across different climate zones), this report examines the impact of climate change on the agriculture sector and the sector's adaptation to that change. Studies in the report measure the climate sensitivity of low-capital agriculture, test whether actual farm performance is as sensitive to climate as agronomic models predict, and compare the climate sensitivity of low-capital farms with the results already calibrated for U.S. agriculture. The goal of the study is to examine farm behavior and test whether there is any evidence that farmers in developing countries currently adjust to their local climates.

The challenge of making climate adaptation profitable for farmers – Evidence from Sri Lanka’s rice sector by Bandara, S., Ignaciuk, S., Hewage, A., Kwon, J., Munaweera, T., Scognamillo, A., Sitko, N.,Food and Agriculture Organization of the United Nations Pdf

Increased incidences of drought and water scarcity due to climate change is an important challenge facing Sri Lanka’s agricultural sector. Identifying farm practices that can reduce its adverse impacts on agricultural production and farmers’ livelihoods is a key policy objective in Sri Lanka. This paper makes use of household survey data collected in Anurādhapura District to evaluate the impacts of 11 drought adaptation practices adopted by farmers in the district. The impacts of the practices are estimated simultaneously along two dimensions: 1) impact on sensitivity to water stress (measured in terms of the probability of experiencing crop loss due to wilting) and 2) impact on household livelihood (measured in terms of total value of crops harvested and total gross household income). After accounting for a wide range of confounding factors, five practices are found to be associated with a reduced sensitivity to water stress. However, only two of these are simultaneously associated with a higher gross value of crops harvested, while none is associated with significant differences in household income relative to non-adopters. The reasons for this vary by practice, but are linked to opportunity costs of household labour and market weaknesses for crops other than rice. Making climate adaptation practices profitable is a key challenge faced by policy-makers and will require a holistic research and extension approach that is bundled with complementary support to market institutions, such as appropriate mechanization services, value chain support for other field crops and input supply systems.

Global Climate Change: Resilient and Smart Agriculture by V. Venkatramanan,Shachi Shah,Ram Prasad Pdf

This book provides essential insights into methods and practices of ‘Climate-smart Agriculture,’ which is driven by the principles of climate resilience and smart resource use in agricultural production. Climate-smart agriculture is a key policy instrument for achieving poverty eradication and a hunger-free world, as well as mitigating the effects of climate change. This book discusses in detail climate-smart agricultural technologies and practices that can reduce the vulnerability of agricultural systems, improve the livelihoods of farmers and other stakeholders, and reduce the greenhouse gas emissions from crop production and livestock husbandry. The agriculture, forestry and other land use (AFOLU) sector produces roughly 10–12 gigatons of CO2-equivalent per year; therefore, sustainable practices for agriculture and related land use hold immense potential to mitigate climate change. The potential impacts of climate variability and climate change on agriculture are extensively documented and articulated, especially with regard to global and national environmental agendas that call for innovation, transformation and climate-resilient advances in agriculture. As the book demonstrates, climate-smart agriculture offers an excellent tool for boosting agricultural output to feed the growing global population; for reducing greenhouse gases emissions from agriculture and other land use; and for protecting agricultural production systems from the impending dangers of climate change.

Climate Change and Agriculture by Robert O. Mendelsohn,Ariel Dinar Pdf

The specific focus of this seminal work is on the economic impact of climate change on agriculture world wide, and how faced with the resultant environmental alterations, agriculture might adapt under varied and varying conditions. Enhanced with a detailed and comprehensive index, Climate Change and Agriculture is highly recommended for academic library environmental studies and economic studies reference collections and supplemental reading lists. The Midwest Book Review Despite its great importance, there are surprisingly few economic studies of the impact of climate on agriculture and how agriculture can adapt under a variety of conditions. This book examines 22 countries across four continents, including both developed and developing economies. It provides both a good analytical basis for additional work and solid results for policy debate concerning income distributional effects such as abatement, adaptation, and equity. Agriculture and grazing are a central sector in the livelihood of many people, particularly in developing countries. This book uses the Ricardian method to examine the impact of climate change on agriculture. It also quantifies how farmers adapt to climate. The findings suggest that agriculture in developing countries is more sensitive to climate than agriculture in developed countries. Rain-fed cropland is generally more sensitive to warming than irrigated cropland and cropland is more sensitive than livestock. The adaptation to climate change results reveal that farmers make many adjustments including switching crops and livestock species, adopting irrigation, and moving between livestock and crops. The results also reveal that impacts and adaptations vary a great deal across landscapes, suggesting that adaptation policies must be location specific. Finally, the book suggests a research agenda for the future. Economists in academia and the public sector, policy analysts and development agencies will find this broad study illuminating.

Agriculture and Adaptation in Bangladesh by Timothy S. Thomas,Khandaker Mainuddin,Catherine Chiang,Aminur Rahman,Anwarul Haque,Nazria Islam,Saad Quasem,Yan Sun Pdf

Bangladesh is extremely vulnerable to the impact of climate change because it is a low-lying, flat country subject to both riverine flooding and sea level rise, and because a large portion of its population is dependent on agriculture for its livelihood. The goal of this research was to examine the likely impacts of climate change on agriculture in Bangladesh, and develop recommendations to policymakers to help farmers adapt to the changes. In this study, we use climate data from four general circulation models (GCMs) to evaluate the impact of climate change on agriculture in Bangladesh by 2050. We use the DSSAT (Decision Support System for Agrotechnology Transfer) crop modeling software to evaluate crop yields, first for the 1950 to 2000 period (actual climate) and then for the climates given by the four GCMs for 2050. We evaluate crop yields at 1,789 different points in Bangladesh, using a grid composed of roughly 10 kilometer (km) squares, for 8 different crops in 2000 and 2050. For each crop, we search for the best cultivar (variety) at each square, rather than limiting our analysis to a single variety for all locations. We also search for the best planting month in each square. In addition, we explore potential gains in changing fertilizer levels and in using irrigation to compensate for rainfall changes. This analysis indicates that when practiced together, using cultivars better suited for climate change and adjusting planting dates can lessen the impacts of climate change on yields, especially for rice, and in some cases actually result in higher yields. In addition, the analysis shows that losses in yield due to climate change can be compensated for, for many crops, by increasing the availability of nitrogen in the soil. Moreover, we used a household survey to collect information on the incidence of climatic shocks in the last five years and adaptation options. The survey was conducted from December 2010 to February 2011, covering data from the previous production year. The results confirm that Bangladesh farmers already perceive the impacts of climate change. In particular, the survey results indicate that of all climate change–related shocks, floods, waterlogging, and river erosion caused the largest loss to rice production. Farmers in our survey lost around 12 percent of their harvest, on average, to some kind of shock, with about half of that attributable to flooding-related issues. The second leading cause of rice crop loss was pests, responsible for around 3 percent of production. Taken together, the results indicate that adaptation efforts in Bangladesh should include adjusting planting dates, using improved cultivars better suited for climate change, improving fertilizer application, exploring increased maize production, and bolstering flood and pest protection for farmers.

Agricultural Impacts of Climate Change [Volume 1] by Rohitashw Kumar,Vijay P Singh,Deepak Jhajharia,Rasoul Mirabbasi Pdf

Conservation agriculture is a sustainable production model that not only optimizes crop yields, but also reaps economic and environmental benefits as well. The adoption of successful conservation agriculture methods has resulted in energy savings, higher organic matter content and biotic activity in soil, increased crop-water availability and thus resilience to drought, improved recharge of aquifers, less erosion, and reduced impacts from the weather associated with climate change in general. Agricultural Impacts of Climate Change examines several important aspects of crop production, such as climate change, soil management, farm machinery, and different methods for sustainable conservation agriculture. It presents spatial distribution of a daily, monthly and annual precipitation concentration indices, Diffuse Reflectance Fourier Transform Infrared Spectroscopy for analyzing the organic matter in soil, and adaptation strategies for climate-related plant disease scenarios. It also discusses solar energy-based greenhouse modeling, precision farming using remote sensing and GIS, and various types of machinery used for conservation agriculture. Features: Examines the effects of climate change on agriculture and the related strategies for mitigation through practical, real-world examples Explores innovative on-farm technology options to increase system efficiency resulting in improved water usage Presents examples of precision farming using climate-resilient technologies
