Available in PDF, EPUB and Kindle. Book excerpt: This paper tries to estimates the impact of climate variability/change on the rice productivity of Assam. For the study purpose we use the time series data (1970-2010) for the respective variables of the study. While we have taken yearly average temperature and yearly average rainfall as a climate variable, where these two variable are also the independent variable of the study along with area of rice cultivation in hectare, area covered by HYV (High Yielding Varieties) seeds in hectare, area covered by irrigation facility in hectare, fertilizer consumption in kg per hectare and average area of land holding in hectare. We used the Cob-Douglas production function in the form of log-log model and the multiple regression counterparts for the analysis, the Cob-Douglas production function technique is the most appropriate for the agricultural sector research. Here it shows, climate as a production input for the agricultural crop productivity. The estimated result shows that the increasing temperature has a negative impact on the productivity of the major crop rice and rainfall has a positive impact on the productivity of this crop in Assam.

Available in PDF, EPUB and Kindle. Book excerpt: This book explains in depth the issues and challenges faced by rice farmers in India in relation to production and productivity, and the possible adaptation strategies to climate change. Based on five years of groundbreaking research on emerging trends in cultivation in major rice growing regions in India, it begins by describing production and yield trends across different rice growing regions. It then offers a comprehensive review of relevant literature and the quantification methodologies and approaches used to analyze the impact of climate change. The book also analyzes climate change impacts on rice productivity and production, applying field-tested quantification methods, such as the Just-Pope production function where time series and cross-section data are simultaneously used for all regions. The results are presented for five geographical regions of India – northern, eastern, western, central and southern – for better comparison and readability. The analyses cover scenarios for both mid-century (2021–2050) and end-century (2071–2100), and in the context of climate change, they also incorporate both medium and high carbon emission scenarios. Thus the future rice production and productivity trends are clearly projected for making necessary interventions. Lastly, the book outlines the essentials of an enabling environment policy and discusses the institutional and policy options necessary to ensure sustainable rice production in India. It also makes the case for introducing appropriate and affordable adaptation strategies to support farmers in different rice-growing regions. The cost–benefit analysis of strategies presented in this book provides an invaluable tool for officials at agriculture departments planning up-scaling of agricultural productivity. The projections are also useful for policy makers and planners developing future investment plans to support rice production in their country. Overall, this book is of interest to a wide audience, including professionals and business enterprises dealing with rice, as well as to academic researchers and students.

Download or read book The Impact of Climate Change in Bangladesh on the Rice Market and Farm Households written by Mst Ashrafun Nahar and published by . This book was released on 2016 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bangladesh is trying to achieve self-sufficiency in domestic rice production but climate change effects on agricultural production makes it challenging to attain the goal. The country is highly vulnerable to the effects of climate change since it is the major cause to rise in sea level, more warm summer, and happening food and cyclone in the country. This study develops an Aggregate Farm Household Model to analyze the impact of potential land loss and yield reduction from climate change on production, consumption, prices, welfare, and the ability of government to achieve self-sufficiency in rice production. The model is calibrated to the Bangladesh rice market in three alternate scenarios using Household Income and Expenditure Survey, 2010 data. The results show that climate change leads to decline in productivity and increase in price of rice in the domestic markets. The reduction in rice productivity decreases rice production while increases production of other non-rice crops. Simulation with a 25% reduction in arable land and 15% reduction in productivity also found that rice land and non-rice agricultural land are also decreasing day by day. However, the decline in rice production leads to greater imports making food security harder to achieve. From simulation analysis, rice yield reduces by 12.67% whereas, the rice price increases by 22.38% and imports by 5.20% with decline in rice productivity by 15% and arable land by 25% in Bangladesh. Alternatively, non-rice crop production increases by 0.19% and the price of non-rice agricultural products decreases by 1.33% in the same scenario. Consequently, the rice and non-rice consumption reduces by 2.28% and 26.24% respectively in both alternate scenarios. The change in climate has more negative effects of consumption of non-rice compared to rice because of the subsistence consumption for rice. In summary, the decline in rice productivity and reduction of arable land leads to a decrease in rice yields, agricultural land and consumption of rice, non-rice agricultural goods, manufacturing goods, and leisure which leads to a reduction in the welfare for the farm households in Bangladesh.

Download or read book Effect of Climate Change in Rice Production in Bangladesh written by Md Shamsuddoha and published by LAP Lambert Academic Publishing. This book was released on 2013 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes findings of the study made to find out the possible effects of climate change on Boro rice, a major food grains that comprise about 60% of rice production in Bangladesh. Simulation results indicate that growth and yield of rice are directly related to temperature, CO2 concentrations, water requirement and planting dates etc. Temperature effects significantly on rice yield and the effect would be more pronounced if temperatures rise in 4 C. Very high temperatures have been predicted for the years 2050 and 2070 due to climate change which would cause yield reductions over 15 to 60 percent. Planting date also showed similar result and this would become more in future with rise of temperatures. CO2 concentrations have a positive impact on rice yield although higher level in future would compensate the adverse effects of increased temperatures to some extent, but it would not be able offset overall impact. Climate change causes significant reduction in rice yields. Development of improved cultivars suitable to withstand high temperatures (2 C to 4 C) and tolerant to water stress may mitigate the production problems projected for the next 50 to 100 years.
Download or read book Rice Production System in Assam written by Bhowmick Bhupendra Ch and published by LAP Lambert Academic Publishing. This book was released on 2015-05-11 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among the food-grains, rice is the principal crop in the state of Assam. The agro-climatic situation prevailing across the zones favours rice cultivation in the state. Hence, the state being one of the main rice growing states of India can contribute a lot to the national economy. The area, production and productivity of crops fluctuate with time. Change in productivity is basically technological and hence, more promising. Therefore, a quantitative assessment of growth and instability as well as adoption pattern of technologies assumes significance in the context of agricultural development in the state. In an agrarian state like Assam, assessment of food security status is of great importance in the backdrop of the higher population growth due to natural growth and influx of people from other states of India and neighbouring countries. In the present study, an attempt has been made to assess the rice production system in Assam with critical analysis of changes in production technologies, adoption, asset acquisition and food security status of rice farmers. The book will be useful to research scholars, policy makers and agricultural planners.

Download or read book Simulating Rice Yields Under Climate Change Scenarios written by Patricia Oteng-Darko and published by LAP Lambert Academic Publishing. This book was released on 2012 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rice is one of the main staple foods in the world and has also become the second most important staple food in Ghana. Policy strategies over the years as captured in the Food and Agriculture Sector Development policy (FASDEP 1), Ghana Poverty Reduction Strategy (GPRS) I and II, Medium Term Agriculture Development Policy (MTADP) and Ministry of Food and Agriculture policy documents have sought to promote rice production to address food security and poverty reduction issues. But rice production is threatened by the effects of climate changes which cannot be overlooked in finding measures to increase production and yield. The CERES-Rice (Ver. 4.0) model was validated for use in simulating rice yields under different climate change scenarios for Ghana using data from the Anum Valley Irrigation Project. 18 years of weather data (1989-2006) was used to run the model. The effects of climate change on the yield of rice will depend on the actual patterns of change in rice growing areas. However, the negative impacts can be averted through appropriate measures such as changes in agronomic practices, development of more temperature tolerant rice varieties and appropriate training of farmers.
Download or read book Global Warming and Agriculture written by William R Cline and published by Columbia University Press. This book was released on 2007-07-30 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: How will global warming affect developing countries, which rely heavily on agriculture as a source of economic growth? William Cline asserts that developing countries have more at risk, such as their production capacity, than industrial countries as global warming worsens. Using general circulation models, Cline boldly examines 2071–99 to forecast the effects of global warming and its economic impact into the next decade. This detailed study outlines existing studies on climate change; Cline finds the Stern Report for the UK government's estimates most reliable; estimates projected changes in temperature, precipitation, and agricultural capacity; and concludes with policy recommendations. Cline finds that agricultural production in developing countries may fall an average of 16 percent, and if global warming progresses at its current rate, India's agricultural capacity could fall as much as 40 percent. Thus, policymakers should address this phenomenon now before the world's developing countries are adversely and irreversibly affected.
