Potential data sets for landcover classification, such as Landsat (or pre-processed data such as the National Land Cover Dataset (NLCD)), are often too coarse for fine-scale research needs or are cost-prohibitive (Quickbird, Ikonos and Geoeye).
A modelling framework is developed to determine the joint economic and environmental net benefits of alternative land allocation strategies.
CONTEXT: With rapidly expanding urban regions, the effects of land cover changes on urban surface temperatures and the consequences of these changes for human health are becoming progressively larger problems.
In course of the research there were considered the problems of the land taxation. Special role of land tax in the system of rationalization of land use was revealed. The experiences of different countries about land taxes were analyzed.
The effect of 19 environmental variables on species richness of macrophytes was studied in 39 Slovak streams. The studied streams were poor in species; in total, 88 macrophyte taxa were found and the average number of macrophytes per sampling site was 4, ranging from 0 to15.
The semi-arid grasslands in Inner Mongolia, China have been degraded by long-term grazing. A series of ecological restoration strategies have been implemented to improve grassland service.
A key activity in Phase 1 of REDD+—the UN’s Framework Convention on Climate Change (UNFCCC) forestry mitigation mechanism—is the development of policies and measures (PAMs) to define where and how emissions reductions and carbon stock enhancements and conservation will be achieved.
This paper provides an investigation of the effectiveness of the main measures applied inRural Development Programs, in particular those for farm structure intervention, atregional/national level on the basis of cluster analysis with spatial econometric tools.
Ecosystem level processes and species interactions have become important concepts in conservation and land management.
