Agricultural drainage, such as runoffs from farmlands and wineries, are contaminated waters. Their management is monitored by environmental protection authorities who set targets of volume or pollutant reductions. Due to large quantities and seasonal variations, the targets are often not met, and effective management remains a problem in many parts of the world. Natural wetlands are known as the 'kidneys' of the earth with unique water purification functions that have long been recognized. Imitating the functions of natural wetlands, constructed wetlands are engineered systems purposely built to treat contaminated waters. They may therefore be called the 'artificial kidneys' of the earth. Rural areas often only have low-value lands available for constructed wetlands. Where large quantities of drainage are produced, farmlands are often adjacent to degraded natural wetlands that have reduced ecosystem functions. Controlled discharge and treatment in the wetlands can potentially be part of an integrated solution to multiple environmental problems. This book includes some recent studies on the fate of pollutants removed from agricultural drainage in wetlands, modelling of wetland performance, innovative systems, and the use of non-hazardous agricultural waste in constructed wetlands for wastewater treatment. These studies enhance our understanding of wetland systems, and will help develop wetland technology towards solving the problems associated with agricultural drainage.

This discussion paper supplements the 2018 World Bank Global Study on Aligning Institutions and Incentives for Sustainable Water Supply and Sanitation (WSS), which promotes holistic approaches in shaping policies, institutions, and regulation. The paper examines how lower-, lower-middle-, and middle-income countries (LMICs) could implement more effective regulation to deliver sustainable WSS outcomes by considering political, legal, and institutional realities. Rather than importing "best practice" models, experience has emphasized the importance of developing "best fit" regulatory frameworks aligned with policy and institutional frameworks of LMICs. To this end, this discussion paper provides an overview of three regulatory aspects-objectives, forms, and functions-to support practitioners as they consider their own regulatory reform options. It discusses the objectives of water sector regulation in LMICs, types of regulatory arrangements and structures that are being used in LMICs, and instruments and methods that regulators in LMICs use to implement their mandated functions and ends with suggestions on where the WSS community goes from here to better understand the preconditions for effective regulation. This paper does not offer definitive conclusions but rather provides suggestions on the way forward through a phased approach to regulatory reform. Importantly, it sheds light on issues that warrant further investigation to determine the future of WSS regulation in LMICs.

The Water Supply, Sanitation and Hygiene (WASH) Poverty Diagnostic in Mozambique is part of a global initiative to improve the evidence base on the linkages between WASH, human development, and poverty. The Diagnostic provides a detailed analysis of sector status, strengths and weaknesses to inform the conditions needed to attain the new Sustainable Development Goals (SDGs) that aim not only for universal access but for safely managed water and sanitation coverage. This report summarizes three background papers of this activity; the first containing the overall summary of findings, a dossier of sector data, and lessons and recommendations; then two technical reports that cover (i) the detailed information and data on the linkages between WASH, health and human development outcomes, and (ii) the analysis of the main institutional barriers that exist in the rural water subsector. The report presents updated evidence and data using diverse analytical tools that contribute to understand why and how WASH investments could be coordinated with other sectors to improve human development outcomes, such as reduced childhood stunting. The information presented in this comprehensive report explores water supply service quality, affordability and availability and offers conceptual framework and institutional diagnostic applied to the rural water sector, where services have been lagging behind in terms of coverage over the past decades.

This note aims at describing the most challenging issues that face water and sanitation sector in West Bank and Gaza (WBandG) and highlighting the possible actions that can improve Palestinian water security. The WBandG Water Supply, Sanitation and Poverty Diagnostic (June 6, 2018) study that has been done by the World Bank, which this note depends on its analysis, concluded that WBandG is a water-scarce lower-middle-income territory with a relatively water-dependent economy and is vulnerable within its geopolitical setting; thus, assuring water security is a priority. Water security requires adequate water resources that are well managed, including management of risks, and water service providers (SPs) that provide sustainable, efficient, and equitable services. The goal of water security has been receding in recent years. Therefore, to improve water security, the sector note recommended two pathways; (a) efficient use of natural and financial resources, (b) collaborative solutions within the region and the Palestinians to improve access to water supply and protect resources, and four pillars; (i) addressing water supply and demand gap, (ii) strengthening the water sector institutions, (iii) enhancing the financial viability and sustainability; (iv) attracting other development partners, including strong cooperation and coordination with Israel.
