Several arthropods are known to be highly beneficial to agricultural production. Consequently it is of great relevance to study the importance of land management and land composition for the conservation of beneficial aphid-predator arthropod species in agricultural areas. Therefore our study focusing on the beneficial arthropod Bembidion lampros had two main purposes: I) identifying the physic...

In an effort to minimize environmental degradation caused by the intensive use of agrochemicals, European Union adopted regulations relevant to afforestation and set aside of agricultural land. The multifunctional role of agriculture enhanced through these regulations and provided adequate motives for a change in the conventional land uses. Cultivators/investors that are interested in afforeste...

There is a global increase in the recognition of environmental, social and economic values of native vegetation, particularly in terms of both sustainability of agricultural production and maintenance of natural resources. The rapid growth of the human population in Sudan (2.6 % per year) stimulated the evolution of mechanized agriculture in the Gedarif Area from 500 ha in the 1940s to about 2....

We conduct a national-scale analysis of the determinants of agricultural land values. The theoretical basis for the study is a spatial city model with stochastic returns to future land development. The empirical model of agricultural land prices is estimated with a crosssection on approximately three thousand counties in the contiguous US. The results provide evidence that option values associa...

The term, biosolids, is generally used to refer to those waste products that have been stabilized by treatment of the sewage sludge for beneficial reuse through appropriate management (Davis, 2002). The agronomic and environmental benefits from the organic material and fertilizing elements contained in the biosolids are essential for maintaining soil fertility. This has been a major reason for ...

The use of satellite technology by military planners has a relatively long history as a tool of warfare, but little research has used satellite technology to study the effects of war. This research addresses this gap by applying satellite remote sensing imagery to study the effects of war on land-use/land-cover change in northeast Bosnia. Though the most severe war impacts are visible at local ...

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 ...
