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.

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.

Changes in land use and land cover (LULC) can result in significant changes in a hydrographic ba- sin flow regime. Future projections about LULC and its interference with water availability help to identify extreme events in advance and help propose appropriate management measures. Thus, this study aimed to make the LULC projection for the year 2030 for the Alto Rio Grande (ARG) sub- basin, located in Southeastern Brazil. This region was chosen because of its intense water resources use and for having recently faced water scarcity as result of prolonged droughts and inadequate water resources management. To identify the LULC trend for the year 2030, the Land Change Modeler (LCM) was used, the map obtained was inserted in the Soil and Water Assessment Tool (SWAT) model previously calibrated and validated for the region’ environmental and climatic conditions. The ARG sub-basin was affected by heavy rains in 2011, which resulted in changes in the landscape due to landslides. This particularity of the region contributed to the projection of LULC for the year 2030 to present an increase in forest and pastures to the agricultural areas detriment. When evaluating the impacts of these changes in water availability, it was observed that the SWAT model presented, for the same rainfall conditions, a reduction in peak streamflows of up to 59% and a reduction in the average monthly flow of up to 63% in 2030 in relation to the LULC observed in 2017. Thus, this study provides an important contribution by identifying a considerable reduction in water availability. These results will help to formulate strategies for water resources management and the adoption of measures to promote water security in the region.

Integrated Water Resources Management (IWRM) is one of the systems thinking approaches that emerged in the 1990s to achieve water security. Ever since, it has been applied in various countries and contexts. However, the implementation of the IWRM is contested. There is paucity of literature and guidelines as to how the concept can be operationalized. In Ethiopia, there is no evidence that IWRM is successfully instituted. The study generated data from household and expert surveys, in-depth interviews, focused group discussions, observations, workshops, and secondary sources. We found that pragmatic water resources management through system approach helps to resolve the problem of fragmentations among various actors, sectors, interest, and priorities. It also enables the operationalization of IWRM as a system approach to secure water resources through strengthening of the interactions of various systems, subsystems, and the elements within the entire basin system. In addition, it is important to facilitate institutional environments such as overcoming financial constraints, considering the scarcity value of water resources and equity issues, as well as ensuring progressiveness of water institutions to emerging circumstances. To this end, strengthening water resources information systems, recognizing and balancing water as economic and public goods, creating awareness among key stakeholders, encouraging the engagement of private sectors in water resources development and management should be considered as mediums of realizing IWRM.Keywords:  IWRM; system thinking; water security; Awash basin; Ethiopia
