This book was released on 2008 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Several studies addressing the supply and demand for food in China suggest that the nation can largely meet its needs in the coming decades. However, these studies do not consider the effects of climate change. This paper examines whether near future expected changes in climate are likely to alter this picture. The authors analyze the effect of temperature and precipitation on net crop revenues using a cross section consisting of both rainfed and irrigated farms. Based on survey data from 8,405 households across 28 provinces, the results of the Ricardian analysis demonstrate that global warming is likely to be harmful to China but the impacts are likely to be very different in each region. The mid latitude region of China may benefit from warming but the southern and northern regions are likely to be damaged by warming. More precipitation is beneficial to Chinese farmers except in the wet southeast. Irrigated and rainfed farmers have similar responses to precipitation but not to temperature. Warmer temperatures may benefit irrigated farms but they are likely to harm rainfed farms. Finally, seasonal effects vary and are offsetting. Although we were able to measure the direct effect of precipitation and temperature, we could not capture the effects of change in water flow which will be very important in China. Can China continue feeding itself if climate changes? Based on the empirical results, the likely gains realized by some farmers will nearly offset the losses that will occur to other farmers in China. If future climate scenarios lead to significant reductions in water, there may be large damages not addressed in this study.

Download or read book Climate Change Impacts on Wheat Productivity Using Ceres Wheat Model written by Raj Kumar Pal and published by LAP Lambert Academic Publishing. This book was released on 2012-04 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change is one of the most important environmental challenges with its implications on food security, water supply, health, energy etc. The wheat production in the country is highly variable due to inter seasonal weather variability and has been projected to be 109 mt by 2020 which needs sincere efforts to mitigate the effect of climatic aberrations. Specifically, the main purpose of this study was to quantify the impact of changes in temperature, solar radiation and CO2 concentration that affect the level of wheat production. The impact of climate change on wheat production can be minimized through adaptability, varietal management and agronomic practices using CERES-wheat model. In Uttarakhand, wheat productivity accounted 15 % to 30 % more with the timely sown crop (20th November) than late sowing. Wheat yield has the positive correlation with CO2 concentration and negatively correlated with temperature. This book, therefore, provides a new metric of success for farmers to deciding agricultural operations and minimize the risks and extremely important to planners in the developing countries which will be the most vulnerable to the effects of global warming.

Download or read book Understanding Options for Agricultural Production written by G.Y. Tsuji and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first premise of this book is that farmers need access to options for improving their situation. In agricultural terms, these options might be manage ment alternatives or different crops to grow, that can stabilize or increase household income, that reduce soil degradation and dependence on off-farm inputs, or that exploit local market opportunities. Farmers need a facilitating environment, in which affordable credit is available if needed, in which policies are conducive to judicious management of natural resources, and in which costs and prices of production are stable. Another key ingredient of this facilitating environment is information: an understanding of which options are viable, how these operate at the farm level, and what their impact may be on the things that farmers perceive as being important. The second premise is that systems analysis and simulation have an impor tant role to play in fostering this understanding of options, traditional field experimentation being time-consuming and costly. This book summarizes the activities of the International Benchmark Sites Network for Agrotechnology Transfer (IBSNAT) project, an international initiative funded by the United States Agency for International Development (USAID). IBSNAT was an attempt to demonstrate the effectiveness of understanding options through systems analysis and simulation for the ultimate benefit of farm households in the tropics and subtropics. The idea for the book was first suggested at one of the last IBSNAT group meetings held at the University of Hawaii in 1993.

This book was released on 2022-09-27 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book analyzes potential yields of six major food crops - rice, wheat, maize, potato, soybean and rapeseed worldwide using both qualitative and quantitative approaches to study both China’s and global food security under climate change. Firstly, it reviews previous studies on potential yields of rice, wheat, maize, potato, soybean and rapeseed worldwide to provide a detailed information of studying on China’s and global food security based on the product’s supply and demand of these crops. Secondly, average and top (national) yields of rice, wheat, maize, potato, soybean and rapeseed since 1961 on global scale are employed to analyze their temporal and spatial variation trends and potential limits. Thirdly, the effects of global warming in climate change on both average and top yields of rice, wheat, maize, potato, soybean and rapeseed since 1961 at global level are analyzed using regression model, and their differences between average and top yields among these crops are identified and compared. Fourthly, the yields and per capita quantity of rice, wheat, maize, potato, soybean and rapeseed in major producer-countries and the world are analyzed to assess the situation and trend of international trade for the products of these crops, respectively. Fifthly, potential yields of rice, wheat, maize, potato, soybean and rapeseed worldwide by 2030 are projected using both trend-regressed models and ARIMA models to estimate the per capita quantity of these crops based on the projection of world population and assess the status of Chinese and global food security in that future. Finally, it provides policy implications and advice on food security for China and the world directing food production by 2030 under climate change.

Download or read book Economic Impacts of Climate Change on Chinese Agriculture written by Peng Zhang and published by . This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change shifts the distributions of a set of climatic variables including temperature, precipitation, humidity, wind speed, sunshine duration, and evaporation. Previous studies have predominantly focused on temperature and precipitation only, while ignoring other climatic variables. These inter-correlated climatic variables are potential determinants for crop yields. Omitting some important climatic variables could bias the estimations of effects of climate change on agriculture. This paper explores the importance of additional climatic variables besides temperature and precipitation. Using the county-level agricultural data from 1980 to 2010 in China, we find that omitting additional climatic variables, especially humidity, dramatically overestimates the negative impacts of climate change on rice and wheat yields. The restricted model, which only includes temperature and precipitation, overestimates the negative impacts of climate change on rice yields by 57% and wheat yields by 87%. The overestimate for corn, however, is minor. These biases are likely caused by overestimating the negative impacts of higher temperatures on crop yields while simultaneously ignoring the positive impacts of the increased humidity induced by climate change. Using the preferred specification, we project that climate change will reduce the yields of rice, wheat, and corn in China by 9.31%, 4.52%, and 45.04%, or decrease the total production by 15.25 million tons, 4.15 million tons, and 58.63 million tons, respectively, by the end of this century.

Download or read book Effect of Climate Change on Wheat Productivity written by Ihsan Elahi and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate is the average of weather situation in a particular area, which affects all parts of ecosystem. Due to industrialization and urbanization, forests are cutting down and converted into living societies. This change in ecosystem disturbs the balance of ecosystem from decomposers to producers and consumers. Important part of ecosystem is plants (producers) that are energy providers. This alteration affects productivity and sustainability of plants. Wheat is staple food, which is highly affected by temperature and CO2 elevation. It not only affects wheat yield but also make wheat vulnerable to several diseases. High temperature causes a high rate of transpiration, which causes drought that ultimately leads to low productivity. A model was designed on drought conditions and result showed that global warming causes serious drought in 60% of wheat-growing areas of the world. Currently, drought affects 15% of wheat productivity. It was predicted that every 2°C shift of temperature can cause severe water shortage in the coming 20 to 30 years. Water shortage at milking and grain filling stage will affect yield. This chapter includes factors affecting climate, impact on wheat growth, yield, and elevation of carbon dioxide, impact on disease severity, prediction model for temperature rise, and CO2 curve in 2050.
