This series of technical briefs aims to provide a solid knowledge base for building or strengthening stakeholder capacities on climate-smart agriculture (CSA) and applying CSA practices to five crops that are critical to the global agri-food sector: coffee, cowpea, maize, rice and wheat. These briefing notes reflect the growing recognition of the need to share knowledge, best practices, lessons learned and experiences on CSA. They are intended to support stakeholders to make the transition to more sustainable and resilient crop production systems and, thereby reach targets laid out in the Sustainable Development Goals. It is our intent to reach a broad range of stakeholders with this knowledge, especially as we begin a new era of global dialogue on how to transform our food systems.

Explore the Relationship between Crop and Climate Agricultural sustainability has been gaining prominence in recent years and is now becoming the focal point of modern agriculture. Recognizing that crop production is very sensitive to climate change, Climate Change Effect on Crop Productivity explores this timely topic in-depth. Incorporating contributions by expert scientists, professors, and researchers from around the world, it emphasizes concerns about the current state of agriculture and of our environment. This text analyzes the global consequences to crop yields, production, and risk of hunger linking climate and socioeconomic scenarios. Addresses Biotechnology, Climate Change, and Plant Productivity The book contains 19 chapters covering issues such as CO2, ozone on plants, productivity fertilization effect, UV (ultraviolet) radiation, temperature, and stress on crop growth. The text discusses the impact of changing climate on agriculture, environment stress physiology, adaptation mechanism, climate change data of recent years, impact of global warming, and climate change on different crops. It explores the overall global picture in terms of the effect of crops to climate change during abiotic stress and considers strategies for offsetting and adapting to ongoing climate change. Details how and why climate change occurs and how it effects crop productivity and agriculture Considers what measures should be taken to mitigate the effect of climate change on agriculture Highlights the effect of climate change on crop productivity, the invention of new technology, and strategies for agriculture practice to adapt to climate change Provides an analysis of the global warming effect on crop productivity due to climate change and long-term agriculture technique development Confirms the asymmetry between potentially severe agricultural damages such as the effect on crop yield due to variation in temperature Reports on the results of experiments to assess the effects of global climate change on crop productivity An asset to agriculturists, environmentalists, climate change specialists, policy makers, and research scholars, Climate Change Effect on Crop Productivity provides relevant information and opportunities for productive engagement and discussion among government negotiators, experts, stakeholders, and others concerned about climate change and agriculture.

The effects of climate change can already be felt around the world, and they will likely impact all facets of human civilization-from health, livelihood security, agricultural production, and shelter to international trade. Since anthropogenic factors are mainly to blame for the current trends in global warming, human intervention will be necessary

Climate change is a significant and growing threat to food security—already affecting vulnerable populations in many developing countries, and expected to affect ever more people in more places, unless action is taken beginning today. Current scenarios for business-as-usual farming under climate change project growing food security challenges by 2050. Worst hit will be underdeveloped regions of the world where food insecurity is already a problem and populations are vulnerable to shocks (Rosegrant et al. 2014). Improvements in agricultural technology and management are expected to increase food security, but if we do not address climate change, climate-related losses in crop and livestock productivity will reduce those gains (Lobell and Gourdji 2012). In this challenging environment, countries will need to contend with shifts in which crops they can best produce, significant changes in global prices, and change in countries’ comparative advantages. New analytical tools that allow policy makers and decision makers to integrate data from the global to the local level offer an important opportunity for countries to identify the most effective ways to address climate change. As the 22nd Conference of the Parties (COP22) gets underway and the role of agriculture as a key element in reducing emissions is widely recognized, countries can use these tools to identify locally appropriate policies that will reduce the impact of climate change on food security over the long term.

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.

Climate-smart agriculture (CSA) is a comprehensive system that requires thorough consideration of local climate, natural environment, market demand, economic and cultural environment. FAO introduced CSA at the Hague Conference on Agricultural, Food Security and Climate Change in 2010 and has been strongly supporting it since then. The development of CSA in China contributes to reaching its carbon peak by 2030 and carbon neutrality in China by 2060. This publication introduces China's CSA development and provides policy proposals. It contains four sections: the background and development status of China's CSA; practices and achievements of China's CSA, including analysing case studies such as the China Climate-Smart Staple Crop Production project funded by the Global Environment Facility (GEF); opportunities and challenges facing China's CSA; and national policy proposals and investments that include local schemes and smallholders for China's CSA.It is critical for China to strengthen its cooperation with international organizations to explore innovative, efficient, resilient, and sustainable climate-adaption technologies for the transformation of agrifood systems.This publication is part of the Country Investment Highlights series under the FAO Investment Centre's Knowledge for Investment (K4I) programme.

​Global climate change is expected to produce increased carbon dioxide levels in the atmosphere, higher temperatures, aberrant precipitation patterns and a host of other climatic changes that would affect all life on this planet. This review article addresses the impact of climate change on fruit trees and the response of the trees to a changing environment. The response of fruit trees to increasing carbon dioxide levels, phenological changes occurring in the trees themselves due to increased temperature and the lower chilling hours especially in the temperate regions, ecophysiological adaptations of the trees to the changing climate, impact of aberrant precipitation, etc. are reviewed. There is very little data on the impact of rising CO2 levels on fruit tree performance or productivity including the temperate region. Based on a large number of observations on the phenology, there is reason to believe that the flowering and fruiting of most species have advanced by quite a few days, but with variations in different crops and on different continents. The chilling hours have also grown shorter in many regions, causing considerable reductions in yield for several species. In the tropics, there is very little work on fruit trees; however, the available data show that precipitation is a major factor regulating their phenology and yield. The ecophysiological adaptations vary from species to species, and there is a need to develop phenological models in order to estimate the impact of climate change on plant development in different regions of the world. More research is also called for to develop adaptation strategies to circumvent the negative impacts of climate change.
