摘要：Pressures and threats to an ecosystem and its function need to be predicted and quantified:only knowing them, actions can be taken to avoid them. This is particularly true when thepressures are created by human actions and decisions. Part of these pressures causeschanges in a) the water (and sediment) regime, b) the input of water and sediment intogiven parts of an ecosystem and c) water availability. These impacts can be estimated bymeans of a simple runoff-erosion model, easy to use and to understand and linked to aspatially distributed description of the landscape where the ecosystem to protect andconserve is located.
