This book addresses the following topics: the contemporary model for water management and alternative approaches; the socioeconomic framework, water policy and institutions; water use for food purposes, water-resources inventory and irrigation; manifestations of welfare loss and water prices; change in dietary patterns and water security; hydrological stress and pressures on water availability; groundwater management problems; vulnerability and climate change; water demand of major crops; gray water footprint and water pollution; gray water footprint and mining; virtual water and food trade; estimates of the water footprint of four key cereals, forage, livestock and bottled drinks. It is the result of a cooperation between 16 researchers from eleven Mexican academic institutions.

This paper seeks to answer a number of basic questions. First of all just what are land tenure rights and water rights? Second, how do the respective regimes compare? Third what linkages, if any, are there between land tenure rights and water rights and, if there are none, does this matter, either in general or as regards specific aspects of the interface? A key objective of the paper is to examine which aspects of the rights interface merit further research. In comparing the two regimes a final subsidiary objective of this paper is to try and identify which areas, if any, in one sector can shed light on areas for future research in the other.

This book presents several complex case studies related to water management and planning in the context of pollution, growing demands, and global climate change in Mexico, but which are also relevant for other countries in Latin America. These concerns are of critical importance for policymakers who are coping with multiple conflicting interests. Water availability in Mexico is polarized, with abundant rainfall and large rivers in the south, and desert-like conditions in the north. The central region, which is the most industrialized, is overpopulated. Mexico City pours millions of cubic meters of “blackwater” into the northern valley daily and receives its clean water from the south. To address these unsustainable conditions, the world's 4th biggest water treatment plant went into operation in 2018. The water infrastructure and governance must satisfy the demands of all sectors, including agricultural, urban, and economic activities. At the same time, water resources are affected by drought, and climate change puts constraints on the supply. As such, regulation and monitoring are important when it comes to adherence to agreed plans and priorities. The book is divided into four sections. 1: Water Availability discusses quantitative aspects, such as supply, methods of calculation, and fracking. 2: Water Quality highlights pollution risks and diagnosis of water resources. 3: Water Allocation examines the sectoral demands and vulnerability due to unsustainable irrigation. 4: Water Governance and Management focuses on laws, urban rules, national parks, planning, and integrated water resources management, among other topics. The chapters include illustrative case studies in Mexico, such as basins, cities, reservoirs, and aquifers, water supply demand assessment, planning, and management.

This book explores how integrated management of environmental resources via a nexus approach can help in achieving the respective Sustainable Development Goals (SDGs). It provides conceptual considerations but mainly practical examples on how to implement a nexus approach in cities and multifunctional land-use systems to increase resource use efficiency and develop a low carbon economy. After sketching out the background and conceptual outline, contributions to the book explore key aspects of the nexus implementation. Specifically, they • Demonstrate how to sustainably use organic waste and wastewater for agriculture, • Explore examples on how to manage multifunctional land-use systems including multipurpose reservoirs, • Highlight the importance of economic incentives for successful nexus implementation, and • Provide a comprehensive perspective on challenges and opportunities of implementation, considering peer-to-peer learning, indigenous knowledge, and stakeholder participation. The chapters in this book shed a new light on key aspects of the interrelation between SDGs and the nexus approach in resilient cities and multifunctional land-use systems, and provide specific examples on how to advance sustainable resources management.

Esta publicacion recoge la experiencia relativa a la puesta en practica de la legislacion sobre el derecho de aprovechamiento de aguas y de vertimiento de aguas residuales a cuerpos hidricos. Las orientaciones legislativas preliminares contenidas en este estudio podran ser de utilidad para responsables politicos, legisladores y funcionarios de gobierno a la hora de redactar nuevas leyes en que se tengan en cuenta los problemas de puesta en practica de la legislacion vinculada a los derechos mencionados."
