Analysis of groundwater management and policies in India

Although groundwater depletion is a global phenomenon, India faces the challenge in its severest of forms. Studies by India’s Central Ground Water Board suggest that in some parts of the country, water tables are receding at 1 meter per year and that the majority of water resources in Northwest and South India are overexploited. Furthermore, two-thirds of India’s 1.2 billion people are involved in agricultural work and are therefore especially vulnerable to groundwater depletion and related climate fluctuations.

Evaluating Water Reforms in Kenya

The Government of Kenya has been implementing wide-ranging reforms in the water sector in accordance with the Water Act of 2002. This study’s objective is to set the stage for long-term rigorous research in Kenya’s water sector by evaluating the performance of reforms in the sector.

Water Sourcing and Sanitation in Rural Kenya

In Kenya, every citizen has a right to water, and the National Water Strategy commits to ensuring that the formal water supply system is accessible to everyone. However millions of Kenyans still don't have adequate access to clean, safe water and rural areas suffer the brunt of this lack of access. This project will explore household water sourcing and sanitation behavior using primary data collected from carefully selected Kenyan sites that optimize on water source and sanitation options.

Resistance to the Regulation of Common Resources in Rural Tunisia

We examine the effect of the introduction of uniform water-charging for aquifer management and provide evidence using a survey-based choice experiment of agricultural water users in rural Tunisia. Theoretically, we show that the implementation of the proposed second-best regulation would result both in efficiency gains and in distributional effects in favour of small landholders. Empirically, we find that resistance to the introduction of an effective water-charging regime is greatest amongst the largest landholders.

Risk perception, choice of drinking water and water treatment: Evidence from Kenyan towns

This study used household survey data from four Kenyan towns to examine the effect of households' characteristics and risk perceptions on their decision to treat/filter water as well as on their choice of main drinking water source. Because the two decisions may be jointly made by the household, a seemingly unrelated bivariate probit model was estimated. It turned out that treating non-piped water and using piped water as a main drinking water source were substitutes.

    Water sharing agreements sustainable to reduced flows

    By signing a water sharing agreement (WSA), countries agree to release an amount of river water in exchange for a negotiated compensation. We examine the vulnerability of such agreements to reduced water flows. Among all WSAs that are acceptable to riparian countries, we find out the one which is self-enforced under the most severe drought scenarios. The so-called upstream incremental WSA assigns to each country its marginal contribution to its followers in the river.

    Nudging Boserup? The Impact of Fertilizer Subsidies on Investment in Soil and Water Conservation

    The new fertilizer subsidies in sub-Saharan Africa are intended to increase agricultural production and ensure development of a fertilizer market. Fertilizer adoption requires complementary inputs, such as investment in soil and water conservation (SWC), for efficient and optimal nutrient uptake, and many fertilizer subsidy programs implicitly assume that fertilizer subsidies crowd in such investments.

    The Impact of Price on Residential Demand for Electricity and Natural Gas

    Climate change will affect the supply of many resources that households consume, including electricity, and natural gas. Although price is considered an effective tool for controlling demand for many resources that households consume, including electricity and natural gas, its impact is poorly understood. Part of the problem is that demand is confounded by block pricing and the interrelated consumption of electricity and natural gas, which prevent easy estimation of price impacts.

    Use of Anthropometric Measures to Analyze How Sources of Water and Sanitation Affect Children’s Health in Nigeria

    We used 2008 DHS data sets to construct child height- and weight-for-age Z-scores and used regression analysis to analyze the effects of different sources of drinking water and sanitation on child health outcomes in Nigeria. We also calculated the probability of a child being stunted or underweight as our measure of malnutrition among children aged 0–59 months.

    Robust placement of sensors in dynamic water distribution systems

    Designing a robust sensor network to detect accidental contaminants in water distribution systems is a challenge given the uncertain nature of the contamination events (what, how much, when, where and for how long) and the dynamic nature of water distribution systems (driven by the random consumption of consumers).

    Decision making under information constraints

    The purposes of placing sensors in water distribution systems vary from complying with water quality regulations, monitoring accidental contamination events, and detecting intentional contamination events.

      Understanding the Basics

      Reform of the water and sanitation sector is occuring in many countries, and offers the potential to improve services to all. Of particular concern, however, is the sitation of the poor, and reform must be designed so that they recieve increased access to affordable services.

        Toward a new Nile Waters Agreement

        Increasing world demands for water call for new institutions and rules to minimize economic and political conflicts. Growing water quality problems from industry and agriculture only further exacerbate supply problems. Such conflicts can jeopardize economic and, in some parts of the world, even social order.

          Water resources management in the Nile basin: the economic value of cooperation

          Since 1999 a multilateral effort termed the Nile Basin Initiative has been underway among the Nile riparians to explore opportunities for maximizing the benefits of the river's waters through cooperative development and management of the basin. However, to date there has been virtually no explicit discussion of the economic value of cooperative water resources development.

            Implications of Ethiopian water development for Egypt and Sudan

            This paper examines the implications for Egypt and Sudan of the development of Blue Nile water resources by Ethiopia. The long-term development program produced between 1958 and 1963 by the Ethiopian government in collaboration with the US Bureau of Reclamation is summarized.
