Implications of land use and occupation for environmental planning and management of the Aquidauana River Basin, Mato Grosso do Sul

Abstract: The hydrographic basins are the spatial units for planning and management of the water resources. Information on the number of inhabitants and the area of the basins contribute to the interaction between the government and the population to be served by natural resource. This work aims to raise subsidies for the management of the hydrographic basin of the river Aquidauana, estimating the number of its inhabitants and its area. Two active management entities have been identified in the Aquidauana river basin: the CIDEMA and CBH Rio Miranda. It was found that the five most important cities of the drainage basin in relation to population and area, part of basin management bodies, may be a facilitator in decision making. It was concluded that due to the low population density of the basin there is a low pressure on resources to be used.

摘要：水文流域（hydrographic basins）是开展水资源规划与管理的核心空间单元。流域人口规模与面积信息，有助于强化政府与目标服务民众就自然资源事务的沟通互动。本研究旨在为阿基道阿纳河（Aquidauana）流域的管理提供决策支撑，并估算该流域的人口总量与流域面积。研究在阿基道阿纳河流域内识别出两家活跃的管理主体：CIDEMA与CBH里约米兰达（CBH Rio Miranda）。研究发现，该流域按人口与面积维度位列前五的城市均为流域管理机构的组成部分，可成为决策推进的重要助力。最终结论表明，该流域人口密度较低，因此可利用的自然资源所承受的开发压力较小。
