We sought to identify priorities and adaptation opportunities for water security across the various Brazilian biomes. With ever-growing demand and water-usage, future climate scenarios suggest that further water resources management constraints are to be endured throughout the next two decades. The unbalance between high-quality water demand and availability in a multisectoral usage context (e.g., domestic, industry, agribusiness) highlights the socio-ecological Nexus+ concept's relevance. In this context, the political and cross-institutional articulation and flexibility play a significant role in steering adaptative actions. These challenges in defining action plans, adequately addressed at a multiscale level with inherent climatic uncertainties, are yet to be overcome in Brazilian water resources management.

Quality Water

Atualmente, cerca de dois bilhões de pessoas carecem de acesso à água de qualidade. No Brasil, tal situação é agravada por questões geográficas, adensamento populacional e poluição. Considerando que a bacia hidrográfica é a unidade de planejamento ambiental no Brasil, pressupõe-se que a realização de seu manejo de forma adequada e aplicação das políticas correlacionadas favorecem a promoção dos usos múltiplos da água. O presente artigo visa fornecer uma visão geral da gestão de recursos hídricos, adotando a bacia hidrográfica como unidade de manejo, abordando aspectos básicos ligados aos recursos hídricos, o histórico do sistema de gestão de recursos hídricos brasileiro e apontar elementos que podem ser empregados no manejo de bacias hidrográficas. Os esforços destinados à gestão dos recursos hídricos no Brasil se iniciaram em 1934, o manejo das bacias hidrográficas deve ser pautado na implementação de estratégias conservacionistas, do saneamento ambiental e da promoção da articulação entre os instrumentos existentes. O processo de gerenciamento deve envolver todos os interessados e os recursos arrecadados com a cobrança pelo uso da água devem favorecer a condução das ações nas bacias hidrográficas. O Grau de Hemerobia consiste em uma ferramenta útil para verificar a influência da paisagem sobre a qualidade da água e eventuais desregulações dos ecossistemas. Water resource management and hydrographic basin management in Brazil: basic elements, historic and strategies A B S T R A C TCurrently, about two billion people lack access to quality water. In Brazil, this situation is aggravated by geographical issues, population density, and pollution. Considering that the hydrographic basin is the environmental planning unit in Brazil, we assumed that the performance of its management in an appropriate manner and application of related policies favors the promotion of multiple water uses. This article aims to provide an overview of water resources management, adopting the hydrographic basin as a management unit, addressing basic aspects related to water resources, the historic of the Brazilian water resource management system and pointing out elements that can be used in the management of hydrographic basins. Efforts destined to the water resources management in Brazil began in 1934, the management of hydrographic basins must be guided by the implementation of conservationist strategies, the implementation of environmental sanitation and promoting the articulation between the existing instruments. The management process needs to involve all stakeholders and the resources collected from charging for the use of water favors the conduct of actions in hydrographic basins. The Hemeroby Degree is a useful tool for verifying the influence of the landscape on water quality and possible deregulation of the ecosystems.Keywords: Aquatic Ecosystems; Management; Planning; Environmental Policy.

Abstract Improper utilization of water resources has the potential to result in reduced availability of high-quality water and adverse effects on societal development. In fact, what appears to be a serious gap in comprehensive water resources studies is the lack of a coherent approach that can link different social, economic and environmental parts within the framework of the integrated water management paradigm to extract strategies and operational plans. Comprehensive water resources management (CWRM) is a process that intends to develop and manage water, land and other resources in a way that maximizes the social and economic well-being of human societies, without compromising the integrity and sustainability of vital ecosystems and future benefits. This chapter discusses the definitions of integrated and comprehensive water resources management describing the steps of using integrated management in practical examples.

Development Framework

In the area of water governance, there has been little systematic comparison between China and India. The intended contributions of this special issue are threefold. A comparative study of water governance between China and India not only provides opportunities for the two countries to draw lessons from each other, but also sheds light on similar challenges in water resources management in other developing countries. In addition, both China and India are key riparian countries in some of Asia's most important international river basins, and their approaches to water conflicts in these rivers have significant impacts not only on water security but also on regional stability. Finally, comparative water governance is a new and undeveloped field of study. This special volume introduces a Modified Institutional Analysis and Development Framework as a tool to facilitate more systematic, theoretical, and comparative approaches to water governance in the context of comparative study of China and India. It does so by specifying various dimensions of the institutional context and how they could explain variations in the performance of the water sector. The aim is to help advance the current theoretical and applied discourse on comparative water governance as a basis for improving water sector performance.

Awash River Basin

Integrated Water Resources Management (IWRM) is one of the system thinking approaches emerged in the 1990s. Since then it has been applied in various countries and contexts. However, the implementation of the IWRM is contested. There are paucity of literature and guidelines as to how the concept can be operationalized. In Ethiopia, there is no evidence that IWRM is successfully instituted. Particularly, IWRM has never been implemented in the Awash River Basin. The study generated data from household and institutional surveys, in-depth interviews, focused group discussions, workshops, and secondary sources. Multiple sources of data were triangulated and thematically summarized. We found that pragmatic water resources management through system approach helps to recognize river basin as a bigger system in which the natural and human systems function. This resolves the problem of fragmentations among among various actors, sectors, interest and priorities. That it facilitates the coordination of various subsystems. The operationalization of IWRM as a system to secure water resources require the establishment and/or strengthening of the interactions of various systems, subsystems, and the elements within the entire basin system. Finally, enabling institutional environments should be considered as a medium of realizing IWRM.
