A agricultura é responsável por 70% da demanda hídrica no Brasil, isso devido fundamentalmente à prática de irrigação. Por outro lado a agricultura irrigada produz 2,7 vezes a mais que a lavoura de sequeiro e emprega em média 1,5 empregos diretos e indiretos por cada hectare irrigado. Classificada em situação crítica a sub-bacia do Boi Branco, localizada na região do Alto Paranapanema, entre os município de Itaí e Paranapanema é um forte polo de agricultura irrigada. O objetivo deste trabalho foi levantar as questões relacionadas aos aspectos de gestão dos recursos hídricos, agricultura irrigada e a participação dos diversos setores de usuários de água da sub-bacia do Boi Branco. Onde se pode observar que os dados quantitativos e qualitativos relacionados aos recursos hídricos nas bacias, apresentam inconsistência tanto na demanda real de água como na disponibilidade efetiva. É preciso uma maior divulgação das informações da sub-bacia do Boi Branco juntamente com investimento em pesquisa e capacitação de todos os envolvidos na gestão dos recursos hídricos.   Palavras Chave: irrigação, pivô central, uso da água, agricultura irrigada.     SAMPAIO NETO, G.

MANAGEMENT OF WATER RESOURCES IN BOI BRANCO SUB-BASIN -SP     2 ABSTRACT   Scarcity of water resources due to climatic factors or increase in consumption due to the intensity of some activities has generated conflicts in several regions of Brazil. Agriculture is responsible for 70% of water demand in Brazil, mainly due to the practice of irrigation. On the other hand, irrigated agriculture produces 2.7 times more than rainfed agriculture and employs on average 1.5 direct and indirect jobs per irrigated hectare. Classified in a critical situation, Boi Branco sub-basin, located in Alto Paranapanema region, Itai and Paranapanema municipalities is a strong irrigated agriculture pole. The objective of this work was to raise issues related to the management of water resources, irrigated agriculture and the participation of  various sectors of water users in  Boi Branco sub-basin. It was observed that  quantitative and qualitative data related to water resources in the basins present inconsistency both in actual water demand and in effective availability. There is a need for greater dissemination of information on Boi Branco sub-basin together with investment in research and training of all those involved in water resources management.   Keyword: irrigation, central pivot, water use, watershed, irrigated agriculture.

The basic aim of this paper is to present the existing conditions and problems of water resources management in Greece. Water demand has increased tremendously over the past 30 years. Despite adequate precipitation, water imbalance is often experienced, due to temporal and regional variations of the precipitation, the increased water demand during the summer months and the difficulty of transporting water due to the mountainous terrain. Integration of reclaimed wastewater originating from the wastewater treatment plant effluents into the water resources management is proposed. This plan exhibits the potential for reducing the pollution loads entering sea or inland waters, while at the same time providing water for irrigation.

Experience of the Central Asia countries in the sphere of reorming of institutional structures responsible for water resources management has been investigated. The outcomes of the works aimed at studying of the results of the integrated management principles application in order to improve structures and methods of water resources management are presented. These outputs enable to reveal special features of the approaches to the management problems solution in the conditions of available water resources abundance and lack in countries with different economic and natural/climatic conditions. The experience was summed up and the typical trends in the water sector management improvement accumulated in the Central Asia countries, as well as the date from other countries with the similar problems including NICs with centralized administrative systems, regions with the many-century traditions of irrigation farming, as well as the countries of transitional economy were revealed. Studying of many countries’ experience concerning adiption of the water resources integrated management allows us to state that there is no sungle ideal or universal model of transition from spatial/territorial management to basin management, no model which can be applied to any country. Analysis of the water resources management systems and institutions enables to formulate the main conditions for effective application of water resources integrated management principles. The paper notes that in spite of substantial progess in water resources management attained in the Central Asia countries many problems including practical application of water legislation, taking into account interest of all sectors of national economy, better coordination between ministeries and agencies involved in water resources management, participation of all stakeholders in taking decisions concerning water supply projects, distribution of juridical and financial obligations between water users and government, and insufficient coordination and agreement in actions at international, national andregional levels stay unsolved.

Abstract Natural water level fluctuations have associated effects on water quality and resident aquatic communities, although their impacts are magnified if the dams have other non-seasonal designated multiple uses. Research demonstrates that excessive water level fluctuations impair ecosystem functioning, ultimately leading to shifts between clear-water and turbid states in shallow lakes. However, these data lack for Manjirenji Dam in Zimbabwe, thus hampering efforts towards effective freshwater resources management in the shallow reservoir. This study analyzed water levels and their fluctuations, and assessed the effects of climatic factors and catchment dynamics using a combination of historical and remote sensed data for the shallow Manjirenji Dam in Zimbabwe. Time series and multiple regression analysis were used to determine water level trends, and the influence of catchment and climatic components in Manjirenji Dam. Lake levels have increased since construction, though their non-significant seasonal variation in the Manjirenji Dam reflects the overlapping effects of catchment and climatic variables. Despite the inferred high stability and resilience, the high fluctuation widths expose the dam to hydrodynamic and climate shocks which have major ecological and conservation implications. A climate change based integrated water resources management approach is necessary for sustainable water resources utilisation in the Manjirenji Dam.

Abstract For optimal water resources management of the Angara reservoirs cascade (a complex “Lake Baikal – Irkutsk, Bratsk, Ust-Ilimsk and Boguchansk reservoirs”) and water users provision in the MIKE 11 software a quasi-two-dimensional simulation hydrodynamic model of the Angara hydroelectric power stations (HPS) cascade from Lake Baikal to the Boguchansk HPS downstream, which is a tool for reproducing the features of the water flow hydrodynamic structure, was developed. A hydrodynamic computer model using the built-in module “Regulating structures” module makes it possible to form reasonable operating modes of the Angarsk cascade of reservoirs that meet the most significant requirements of water users: ecology, fisheries and utilities, transport and energy. Hydrodynamic calculations and the flood zones obtained in the GIS project of the territory showed that catastrophic phenomena in the floodplain and coastal zone of Irkutsk occur even when releases into the lower pool of the Irkutsk reservoir exceed 3200 m3/s. The developed hydrodynamic model of the Angarsk cascade of reservoirs makes it possible to determine the objects and floodplain areas most susceptible to flooding in the downstream of the Irkutsk HPS for further development of scientifically based measures to protect them, prevent flooding and develop evacuation plans in an emergency.

General Secretary Xi Jinping proposed to take water resources as the maximum rigid restriction, emphasize using water resources as its capacity permits, and actively explore new ways of high-quality development with regional characteristics. Yongkang is a water shortage county in the southern water-rich area. The contradiction between insufficient water supply and rapid economic and social development and continuous improvement of ecological environment is more prominent. In this paper, industrial water users are taken as the key control objects, and the added value of unit water consumption is taken as the rigid constraint index of water resources. It is incorporated into the reform of “heroes per acre” and integrated with the existing water resources management system to design the collaborative promotion mechanism framework of general rigid constraint of water resources. Then, the application practice in Yongkang is carried out, and the responsibilities of various administrative departments are clarified.

Development Stages

Water resources management is increasingly important for sustainable economic and social development. A coherent division of the development stages is of primary importance for selecting and implementing related water resource management strategies. Using evolving supply–demand relationships, this paper proposes a framework that considers water development stages to present a series of dynamic relationships between water demand changes and overall economic development. The framework is applied to China to advance the understanding of how demand evolves at different stages of water resources development under specific socioeconomic circumstances, and of strategic choices in general. The case of China explains how water resources management has gradually improved during distinct socioeconomic development stages. It illustrates the varieties and effectiveness of water policies made to adapt to changing demand over the course of socioeconomic development. The framework can be potentially applied to other countries or regions to identify the development stage in order to select proper water management strategies.
