the multi-criteria decision making model is an important tool for decision making in water resource management. in this paper, the topsis model was used to rank seven flood management options in the gorganrood river flood management project, including conservation of natural condition, golestan reservoir management, levee construction, diversions-channel construction, flood forecasting and warn...

Systematic conservation planning increasingly underpins the conservation and management of marine and coastal ecosystems worldwide. Amongst other benefits, conservation planning provides transparency in decision-making, efficiency in the use of limited resources, the ability to minimise conflict between diverse objectives, and to guide strategic expansion of local actions to maximise their cumu...

Selecting and conserving lands for biodiversity: The role of remote sensing" (2009). a b s t r a c t a r t i c l e i n f o A major focus of conservation is on protecting areas to ensure the persistence of biological diversity. Because such areas may be large, not easily accessible, subject to change, and sensitive to the surrounding landscape, remote sensing can be a valuable tool in establishi...

Since 1930, areas of state-managed forest in the central Himalayas of India have increasingly been devolved to management by local communities. This article studies the long-run effects of the devolution on the cost of forest management and on forest conservation. Village council-management costs an order of magnitude less per unit area and does no worse, and possibly better, at conservation th...

nowadays soil erosion is considered as a serious threat to human's life and his welfare. when soil erosion not properly controlled, the fertility would gradually decrease. adoption of appropriate soil conservation practices along with socio-economic factors' assessment can be used to increase farmers' awareness and acceptance of soil conservation, and to diminish soil erosion dam...

There is increasing concern for the conservation of sharks among scientists, environmental conservation advocates, and the interested public, but misunderstanding among policy non-specialists about which conservation and management policies are available, and which might work best for certain situations, persists. Here we present a review of fisheries management and conservation literature rela...

Monitoring and research activities may hinder rather than improve conservation in tropical countries. Those concerned with conservation—particularly academics and aid agencies—too often overlook the practical realities of achieving conservation in the tropics. As a result, many initiatives divert scarce resources away from fundamental management priorities. I identify some critical threats to b...

1. The conservation of insects is not a priority for most urban dwellers, yet can be accomplished in urban settings by the careful design of urban nature. Our goal is to foster cross-talk between practitioners of insect conservation biology who develop the knowledge base and professional design practitioners who are poised to apply this knowledge in designs and management plans for urban green ...

management model desirable to establish the life cycle of various commodities in different organizations is a closed-loop supply chain. in this paper, according to classic models in white and brown goods, a unified framework is used to implement in a military logistics company. it seems that using this model, improved lifecycle management, environmental conservation and improvement of services ...
