Showing items 27973 through 27981 of 73560.This work presents a new four-tier hierarchical change-point algorithm designed to detect land-cover change from satellite data. We tested the algorithm using Global Inventory Modelling and Mapping Studies (GIMMS) data for eastern Africa.
Land management is closely related with the balanced interaction of crop production, agriculture, animal husbandry, environmental management. It is based on maximum use of climatic resources, biological, geographical and environmental factors.
Urbanization is viewed as endangering more critical habitats of global value and is more ubiquitous than any other human activity affecting biodiversity, climate, water and nutrient cycles at multiple scales.
Inventories of tree species are often conducted to guide conservation efforts in tropical forests. Such surveys are time consuming, demanding of expertise, and expensive to perform and interpret. Approaches to make survey efforts simpler or more effective would be valuable.
The poor water condition in agricultural watersheds in Poland provides evidence of a major impact of this sector on water quality, especially with regard to nutrients.
Sub-pixel mapping is a technology to obtain the spatial distribution information of land cover within mixed pixels. In this letter, two kinds of edge-directed interpolation algorithms are proposed.
Emerging concerns for environmental flows translate into reforms that aim to preserve minimal flows in rivers. These policy measures have consequences for traditional right-holders: how to share between consumptive users the new scarcity created by the protection of instream flows?
Bats are considered important bioindicators and deliver key ecosystem services to humans. However, it is not clear how the individual and combined effects of climate change and land-use change will affect their conservation in the future.
There is a long tradition of river monitoring using taxonomy-based metrics to assess environmental quality in Europe via benthic macroinvertebrate communities. A promising alternative is the use of their species life-history traits.
