Book Description
This study assesses the changing consumption patterns of rice in Bangladesh and its implications on water demand by 2030. Rice dominates food and water consumption patterns in the country; it contributed to 72% of the total calorie supply from food, and 81% and 79% of the total cropped and irrigated area, respectively, in 2010. Forecasts using time series models show rice demand for food consumption, which was 172 kg/person/ year in 2008, will have a negligible increase by 2 kg/person by 2030. The demand for rice for feed will double with increasing animal products in the diet, which is only 4% of the calorie intake in 2008. Between 2000 and 2010, the total population and demand for rice have increased by 15% and 22%, and these will increase further by 22% and 25%, respectively, over the next two decades. Forecasts of rice yield, area and production show that the country can meet the increasing demand for rice and can also have substantial production surpluses. However, the rice surpluses will come at a considerable environmental cost, because the demand for groundwater consumptive water use from irrigation alone could exceed the natural recharge in many locations. Bangladesh can mitigate potential water crises by limiting rice production to meet the requirements of self-sufficiency. Increases in water productivity of both Aman (wet season) and Boro (dry season) rice production can help too. A carefully designed deficit irrigation regime for Boro rice can increase transpiration, yield, water productivity and production, and reduce the pressure on scarce groundwater resources. Simultaneously, attention must also be given to exploring the potential of recharging groundwater using the vast amount of monsoon floodwaters to alleviate the stress on groundwater resources.

Book Description
It is beyond doubt that the interconnectedness between food, energy, water security and environmental sustainability exists and is getting amplified with increased globalization. It has been recognized that efforts to address only one part of a systemic problem by neglecting other inherently interlinked aspects may not lead to desirable and sustainable outcomes. In this perspective, policy- and decision- making requires a nexus approach that reduces trade-offs and builds synergies across sectors, and helps to reduce costs and increase benefits for humans and nature compared to independent approaches to the management of water, energy, food and the environment. In the past, work related to the Nexus has looked at the interactions between water and food or water and energy, but there has been a reluctance to bring forward a broader systematic perspective that captures the multiple sectors and resource dependencies while understanding its cost to the environment if we neglect these linkages. This book is a compilation of thirteen papers published previously as a special issue of Water International, contains significant pieces of work on the W-E-F nexus focusing on relevant tools, solutions and governance at local and broader human scales.

Book Description
Undoubtedly, drinking water of an acceptable quality has become a scarce commodity. Water shortage is becoming a major concern all around the world due to limited freshwater resources as well as the high cost of freshwater transportation from freshwater-rich areas to arid areas. As a result, solutions such as water recycling and desalination of saline or brackish water are being introduced and emerging worldwide as alternative ways of supplying water. Desalination of seawater is known to be one of mankind’s earliest forms of water treatment, and it has become one of the most sustainable alternative solutions to provide freshwater for many communities and industrial sectors. This book aims to cover the challenges and opportunities in desalination processes.

Book Description
The rural economy in Bangladesh has powerfully advanced economic growth and substantially reduced poverty, especially since 2000, but the remarkable transformation and unprecedented dynamism in rural Bangladesh remain an underexplored, underappreciated, and largely untold story. Dynamics of Rural Growth in Bangladesh: Sustaining Poverty Reduction tells that story and inquires what specific actions Bangladesh might take—given the residual poverty and persistent malnutrition—to accelerate and channel its rural dynamism to sustain the gains in eliminating poverty, achieving shared prosperity, and advancing national aspirations to achieve middle-income status. The central element of this study, undertaken with the Government of Bangladesh Planning Commission to address key questions elicited through extensive consultation, is an empirical analysis that illuminates the underlying dynamics of rural growth, particularly the role of agriculture and its relationship to the nonfarm economy. Using all sources of data available for the macro-, meso-, and microhousehold levels, the analysis provides new evidence on changes in the rural economy and the principal drivers of rural incomes. It also examines market performance for high-value agricultural products and agriculture†“nutrition linkages, based on new surveys and analysis. The resulting evidence, examined in light of the rich knowledge of rural development in Bangladesh, is used to delineate the implications for policy and the strategic priorities for sustaining future rural development, poverty reduction, food security, and nutrition. The effects of policy reforms, changes in technology, and investments in infrastructure and human capital described here, along with the persistent enterprise of rural Bangladeshi households, offer a compelling case study of how mutually reinforcing actions can trigger the highly-sought-after virtuous cycle of rural development. The findings clearly demonstrate the pro-poor nature of agricultural growth and its catalytic role in stimulating the rural nonfarm economy. They show that households have no linear or predictable pathway out of poverty; instead, they wisely employ a combination of farm and nonfarm income strategies to climb out of, and then stay out of, poverty. The results represent a strong contribution to the global thinking on rural transformation and on how agriculture in particular sustains the economic momentum that fosters poverty reduction and more widespread prosperity.

Book Description
Increasing income and urbanization are triggering a rapid change in food consumption patterns in India. This report assesses India’s changing food consumption patterns and their implications on future food and water demand. According to the projections made in this study, the total calorie supply would continue to increase, but the dominance of food grains in the consumption basket is likely to decrease by 2050, and the consumption of non-grain crops and animal products would increase to provide a major part of the daily calorie supply. Although the total food grain demand will decrease, the total grain demand is likely to increase with the increasing feed demand for the livestock. The implications of the changing consumption patterns are assessed through consumptive water use (CWU) under the assumptions of full or partial food self-sufficiency.

Book Description
In the Dry Zone of Myanmar, improved access to water is widely acknowledged as being vital for livelihood enhancement and the general well-being of around 10 million people, most of whom depend on agriculture. Thus, expanding the sustainable use of groundwater is of great importance for socioeconomic development. According to this study, opportunities for accessing groundwater are generally good, and development of the resource has steadily increased over the years. However, there still appears to be good prospects for expanding groundwater use for irrigation, with a view to increasing agricultural production. Provision of affordable mechanical technologies for drilling wells and support with credit facilities to purchase small-capacity motorized pumps for irrigation could improve food security and livelihoods, where there is potential to expand groundwater use. Replenishable groundwater resources of the Dry Zone are likely to be less than previously thought. Thus, it is important to find the right balance between increasing development of the resource for enhanced irrigation, while also protecting its existing beneficial use for communities and the environment.

Book Description
Although the Ganges River Basin (GRB) has abundant water resources, the seasonal monsoon causes a mismatch in water supply and demand, which creates severe water-related challenges for the people living in the basin, the rapidly growing economy and the environment. Addressing these increasing challenges will depend on how people manage the basin’s groundwater resources, on which the reliance will increase further due to limited prospects for additional surface storage development. This report assesses the potential of the Ganges Water Machine (GWM), a concept proposed 40 years ago, to meet the increasing water demand through groundwater, and mitigate the impacts of floods and droughts. The GWM provides additional subsurface storage (SSS) through the accelerated use of groundwater prior to the onset of the monsoon season, and subsequent recharging of this SSS through monsoon surface runoff. It was identified that there is potential to enhance SSS through managed aquifer recharge during the monsoon season, and to use solar energy for groundwater pumping, which is financially more viable than using diesel as practiced in many areas at present. The report further explores the limitations associated with water quality issues for pumping and recharge in the GRB, and discusses other related challenges, including availability of land for recharge structures and people’s willingness to increase the cropping intensity beyond the present level.

Book Description
By altering evapotranspiration and influencing how water is routed and stored in a basin, natural and agrarian ecosystems affect river flow. To quantify the impact of ecosystems on streamflow in two large river basins in Asia and Africa, simple statistical relationships were calculated, enabling flow characteristics to be ascertained from basic catchment features. This approach allows the impact of specified land-use change on streamflow to be determined. For example, it shows that extending paddy areas in the Mekong River Basin reduces downstream low flows, while conversion of forests to crops increases the magnitude of downstream floods in the Volta River Basin. The approach could assist river basin planners to better account for flow-related ecosystem services.
