Book Description
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 changerelated 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.

Book Description
The existing literature shows that climate change will likely affect several of the dimensions that determine people’s food security status in Bangladesh, from crop production to the availability of food products and their accessibility. Crop diversification represents a farm-level response that reduces exposure to climate-related risks and it has also been shown to increase diet diversity and contribute to the reduction in micronutrient deficiencies. In fact, the Government of Bangladesh has several policies in place that encourage and support agricultural diversification. However, despite this support the level of crop diversification in the country remains low. Women empowerment has been linked to diversified diets and positively associated with better child nutrition outcomes. Furthermore, although traditionally their role in agriculture tends to be undervalued, women involvement has already been shown to affect agricultural production choices and enhance technical efficiency. This paper connects three different areas of inquiry - climate change, gender and nutrition – by exploring whether women’s empowerment in agricultural production leads to increased diversification in the use of farmland. Specifically, we use a series of econometric techniques to evaluate whether there is sufficient evidence to claim that a higher levels of empowerment lead to greater diversity in the allocation of farmland to agricultural crops. Our results reveal that indeed some aspects of women empowerment, but not all, lead to a more diversified use of farmland and to a transition for cereal production to other uses like vegetables and fruits. These findings provide some possible pathways for gender-sensitive interventions that promote crop diversity as a risk management tool and as a way to improve the availability of nutritious crops.

Book Description
About the Research for Development (R4D) Learning Series The WLE Research for Development (R4D) Learning Series is one of the main publication channels of the program. Papers within the series present new thinking, ideas and perspectives from WLE research with a focus on the implications for development and research into use. Papers are based on finalized research or emerging research results. In both instances, papers are peer-reviewed and findings are based on sound scientific evidence and data, though these might be incomplete at the time of publication. The series features findings from WLE research that emphasize a healthy functioning ecosystem as being a prerequisite to sustainable intensification, resilience of food systems and human well-being. The series brings together multi-disciplinary research, global synthesis and findings that have implications for development practitioners and decision makers at various levels.

Book Description
Agriculture is always vulnerable to unfavorable weather events and climate conditions. The impacts of climate change on agriculture crop production are global concerns as well as Bangladesh. To measure Climatic and Hydrological effects on different types of crop productions in Bangladesh, Multiple Regression Model has been used as a measuring tools of cause-effect relation. At the same time, Auto Regressive Integrated Moving Average with external regressor, that is, ARIMAX model has used considering the time effects, because the data-set used in this study is a time sequence data. This is completely a new study for measuring the Climatic and Hydrological effects by using ARIMAX model. Again, from the comparative study, Multiple Regression is the best model for vegetable, potato and cereal production; and ARIMAX is the best model for rice, jute and species production for measuring the climatic and hydrological effects on agricultural production in Bangladesh.

Book Description
This paper measures the economic impact of climate on crops in Kenya. The analysis is based on cross-sectional climate, hydrological, soil, and household level data for a sample of 816 households, and uses a seasonal Ricardian model. Estimated marginal impacts of climate variables suggest that global warming is harmful for agricultural productivity and that changes in temperature are much more important than changes in precipitation. This result is confirmed by the predicted impact of various climate change scenarios on agriculture. The results further confirm that the temperature component of global warming is much more important than precipitation. The authors analyze farmers' perceptions of climate variations and their adaptation to these, and also constraints on adaptation mechanisms. The results suggest that farmers in Kenya are aware of short-term climate change, that most of them have noticed an increase in temperatures, and that some have taken adaptive measures.

Book Description
Managing climate variability and change remains a key development and food security issue in Bangladesh. Despite significant investments, floods, droughts, and cyclones during the last two decades continue to cause extensive economic damage and impair livelihoods. Climate change will pose additional risks to ongoing efforts to reduce poverty. This book examines the implications of climate change on food security in Bangladesh and identifies adaptation measures in the agriculture sector using a comprehensive integrated framework.First, the most recent science available is used to characterize current climate and hydrology and its potential changes. Second, country-specific survey and biophysical data is used to derive more realistic and accurate agricultural impact functions and simulations. A range of climate risks (i.e. warmer temperatures, higher carbon dioxide concentrations, changing characteristics of floods, droughts and potential sea level rise) is considered to gain a more complete picture of potential agriculture impacts. Third, while estimating changes in production is important, economic responses may to some degree buffer against the physical losses predicted, and an assessment is made of these. Food security is dependent not only on production, but also future food requirements, income levels and commodity prices. Finally, adaptation possibilities are identified for the sector. This book is the first to combine these multiple disciplines and analytical procedures to comprehensively address these impacts. The framework will serve as a useful guide to design policy intervention strategies and investments in adaptation measures.
