Over the last decades land development has gradually shifted from an instrument aimed at the improvement of an area in an agricultural way to a multi-functional instrument, in which more attention is paid to the possibilities to conserve and improve, e.g. ecolog...
Land cover type is a crucial parameter that is required for various land surface models that simulate water and carbon cycles, ecosystem dynamics, and climate change. Many land use/land cover maps used in recent years have been derived from field investigations and remote-sensing observations. However, no land cover map that is derived from a single source (such as satellite observation) proper...
Study on land ecological safety has become a forefront topic of regional sustainable development. The paper constructed an evaluation index system of land ecological safety. Then it discussed the ranges of indexes corresponding to each evaluation grade. Considering the illegibility and uncertainty in land ecological safety evaluation, the paper combined fuzzy matter-element and entropy method t...

Results of survey of stakeholders regarding knowledge of and attitudes towards feed intake, efficiency and genetic improvement concepts" (2016).
Coastal aquatic ecosystems are increasingly affected by diffuse source nutrient water pollution from agricultural activities in coastal catchments, even though these ecosystems are important from a social, environmental and economic perspective. To warrant sustainable economic development of coastal regions, we need to balance marginal costs from coastal catchment water pollution abatement and ...
