Although there exists in the U.K. a high degree of control of industrial and agricultural anthrax in man and anthrax in animals originating either from animal products or from materials contaminated by contact with them, total control of anthrax in this country seems unlikely to follow until the disease is eliminated from livestock in the enzootic areas abroad. This view rests on the probabilit...

Conventional wisdom postulates that leaching losses of N from agriculture systems are dominated by NO3 – . Although the export of dissolved organic nitrogen (DON) into the groundwater has been recognized for more than 100 yr, it is often ignored when total N budgets are constructed. Leaching of DON into stream and drinking water reservoirs leads to eutrophication and acidifi cation, and can pos...

Studies on sustainable agricultural have not paid adequate attention to farmers' behaviour regarding sustainability. The objectives of this research were: 1) to determine the relationship between socio-economic and farming factors with “sustainable agricultural knowledge”, 2) to predict “sustainable agricultural knowledge” based on socio-economic and farming factors, and 3) to determine the rel...

Agricultural land use commonly leaves a persistent signature on the ecosystems that develop after agricultural abandonment. Th is agricultural legacy limits the biodiversity supported by post-agricultural habitats compared to remnant habitats that have never been used for agriculture. In particular, beta diversity (variation in community composition across space) at both large and small spatial...

Global food demand will strongly rise over the next decades, due to population growth, average income increases, and trends towards higher consumption of animal products. Agricultural and food production already account for 70 percent of total freshwater withdrawals in the world. In addition, future water demand from private households, industry and for environmental purposes will also rise. Ov...

The current state of the art in erosion research does not provide answers about the “where” and “when” of wind erosion in European agricultural lands. Questions about the implications for the agricultural productivity remain unanswered. Tackling this research gap, the study provides a more comprehensive understanding of the spatial patterns of land susceptibility to wind erosion in European agr...

In agricultural landscapes, the Turkey Vulture Cathartes aura feeds mainly on carcases of domestic animals. In spring 2017, data on 214 flocks of Turkey vultures were collected in a road survey in Cuba (in total 2384 km). Turkey Vultures were found to be common accross Cuba, but flock size varied between habitats, reaching a maximum of 43 in valleys and 31 in agricultural landscapes with domest...
