It presents a methodology for developing plans for optimum allocation of land area and water, considering performance measures such as productivity, equity and adequacy.
Today, competing land use is continuing to occur in many developed regions. In the Agricultural Development Zone of Western Sydney Region, which is characterised by complex landscape patterns, land use competition is widespread.
The conservation of individual plant and animal species has been advanced greatly by the World Conservation Union's (IUCN) development of objective, repeatable, and transparent criteria for assessing extinction risk, which explicitly separate the process of risk assessment from priority-setting.
The environmental setting (e.g., climate, topography, geology) and land use affect stream physical characteristics singly and cumulatively. At broad geographic scales, we determined the importance of environmental setting and land use in explaining variation in stream physical characteristics.
Human land use of forested regions has intensified worldwide in recent decades, threatening long-term sustainability. Primary effects include conversion of land cover or reversion to an earlier stage of successional development.
Riparian ecosystems are interfaces between aquatic and terrestrial environments recognized for their nutrient interception potential in agricultural landscapes. Stream network maps from a broad range of map resolutions have been employed in watershed studies of riparian areas.
Tsinghua University, one of the top universities in China, has conducted a lot of collaborative R&D projects with multinational companies in the recent years. One of tough issues in the collaborative R&D is to deal with the intellectual property rights.
The introduction, establishment and spread of non-native earthworm species in North America have been ongoing for centuries.
As a global and regional environmental problem, desertification assessment is an instrumental component in developing global/regional actions plans aimed at preventing and/or eradicating desertification issues.
