Hydrogeology of the Eastern Ganges Basin: an overview
The Ganges Basin is a part of the Ganges-Brahmaputra-Meghna (GBM) River Basin and is one of the most populated (600 million) river basins in the world. This study focuses on the Eastern Ganges Basin (EGB) and covers India (Bihar, Jharkhand and West Bengal), Bangladesh and the Nepal Terai. Poverty is acute in the EGB, where household incomes are low, food security is not assured and devastating floods (and also water shortages) occur too often. The EGB is underlain by one of the most prolific aquifers in the world. Yet, farmers struggle to cope with dry spells and droughts because of their inability to access groundwater. Huge untapped groundwater, surplus surface water, and enormous plains a...
Beyond Resource Wars
An argument that resource scarcity and environmental degradation can provide an impetus for cooperation among countries. Common wisdom holds that the earth's dwindling natural resources and increasing environmental degradation will inevitably lead to inter-state conflict, and possibly even set off “resource wars.” Many scholars and policymakers have considered the environmental roots of violent conflict and instability, but little attention has been paid to the idea that scarcity and degradation may actually play a role in fostering inter-state cooperation. Beyond Resource Wars fills this gap, offering a different perspective on the links between environmental problems and inter-state co...
Rapid Assessment of Water Availability and Appropriate Technologies
Limited access to water is a key reason why millions of poor farmers struggle to grow enough food and marketable crops to improve their lives. Public sector agencies, civil society organizations and donors seeking to improve small-scale farmers’ access to water resources face limited data on the location and accessibility of water resources. This paper addresses this gap by providing a tested method to assess water resources that small-scale farmers can access affordably and sustainably. This paper also supports the selection of appropriate water access and application technologies for available water resources. The method described is rapid and relatively inexpensive; it uses a phased approach to assess a broad-scale area (e.g., a country or region); and then gathers more information in locations that have higher potential for affordable water access by small-scale farmers.
Improving the Supply Chain of Motor Pumps to Expand Small-scale Private Irrigation in Zambia
During the past decade, smallholder groundwater irrigation with motor pumps has increased considerably in Zambia. The present study analyzes an important, but hitherto ignored, factor for adoption: the supply chain of imported motor pumps. Findings include types of pumps; organization of import, wholesale and retail, including after-sales services; fiscal measures (import duty waiver and VAT zero rating); prices of pumps; and financing facilities to the farmers. The main obstacles for farmers were found to be: the highly centralized supply chain and financing facilities in urban hubs; lack of information, also about prices, which vary significantly even for the same make and model of pump; lack of information and training about proper use and maintenance; and lack of financing facilities. The Zambia National Farmers Union seems best placed to remove these obstacles.
Gender Aspects of Small-scale Private Irrigation in Africa
This Working Paper presents methodological and substantive findings of gender-differentiated quantitative farm household surveys about smallholder’s private irrigation technology adoption in Ghana and Zambia. Focusing on three gender variables, household headship, labor provision and plot management, the paper examines adoption rates, types of technologies and gendered labor provision in female- and male-headed households; compares adoption rates on women’s own plots with overall rates; compares women’s decision-making on irrigated plots and rainfed plots; and examines impacts of targeting strategies. Findings suggest that women are proactive irrigation adopters in spite of the many obstacles they face. Removing those obstacles serves both gender equality and irrigation policies.
Integrated Flood Risk Management
This book tackles the question of how we can manage flood-related disaster risks, such as from typhoons, monsoons, and torrential rain, which have been intensified by climate change and have generated unprecedented floods, landslides and debris flows worldwide. It presents recent conceptual developments in disasters, risk and resilience, and surveys UN policies on environment and development as well as disaster management. Sustainable and resilient development requires an integrated approach and human empowerment. Japan provides a useful example of effective flood management and disaster recovery in its current strategies for river and basin integrated flood management. Very few English-lang...
A framework to Understand Gender and Structural Vulnerability to Climate Change in the Ganges River Basin
As climate change becomes accepted as a reality in the scientific community, it is critical to continue to understand its impact on the ground, particularly for communities dependent on agriculture and natural resources. This report reviews the extensive literature on the vulnerability to climate change in South Asia, with a focus on gender. It highlights how vulnerability is intricately connected to existing social structures. With respects to gender inequalities, the report reviews how men and women are affected in different ways by climate shocks, while differing access to resources and cultural ideologies mean that their capacity to ‘adapt’ is also not equal. The report also notes the importance of other axes of inequality (caste, class and ethnicity) in shaping gendered vulnerability. It concludes by offering insights into potential ways forward to promote more equitable adaptation to change through improved policies and practices.
Review of Literature on Chronic Kidney Disease of Unknown Etiology (CKDu) in Sri Lanka
This manuscript undertakes a review of current published information (peer-reviewed and grey literature) on Chronic Kidney Disease of Unknown Etiology (CKDu) in Sri Lanka. It attempts to provide an overview of the possible environmentally-induced causal factors that have been implicated in the development of the disease, and identifies the gaps in research and recommends potential areas for future research. The review specifically captures the potential role that agriculture and water resources may play as causal factors in the development of the disease, and calls for a systematic approach and stresses the need for an integrated multi-disciplinary research effort to address the problem.
A Global Green New Deal
Meeting the short run challenges of reviving the worldwide economy need not mean sacrificing long run economic and environmental sustainability. A Global Green New Deal (GGND) is an economic policy strategy for ensuring a more economically and environmentally sustainable world economic recovery. Reviving growth and creating jobs should be essential objectives. But policies should also aim to reduce carbon dependency, protect ecosystems and water resources, and alleviate poverty. Otherwise, economic recovery today will do little to avoid future economic and environmental crises. Part One argues why a GGND strategy is essential to the sustainability of the global economy. Part Two provides an overview of the key national policies whilst Part Three focuses on the global actions necessary to allow national policies to work. Part Four summarizes the main recommendations for national and international action, and discusses the wider implications for restructuring the world economy towards 'greener' development.
Water Resources and Inter-Riparian Relations in the Nile Basin
Human demand for water resources is rising at an alarming rate in response to rapid population growth, rival development requirements, and the depletion of ecological resources. In this book, Okbazghi Yohannes examines the various facets of the competition for water resources among the ten Nile River Basin countries as they compete to harness the river's resources for purposes of irrigation-based agriculture and hydropower-based industrialization. Through a careful investigation of the rival states' strategies to capture greater shares of water resources, Yohannes assesses the lasting impact on the watershed ecology in the basin and on the hydrological demand of the river itself. He proposes the formation of a radically different water regime to address the looming demographic crisis, the stark regional food insecurity, and the region's collapsing hydro-ecology. This book shows how the effort to construct a regional water regime cannot be separated from the necessity to construct an ecologically sustainable internal water regime in each co-basin state, particularly in terms of ecological resources conservation and ecosystem services protection.
