Surplus food production has led to increased interest in taking land out of arable farming, notably under set-aside regulations, and converting it into grasslands that resemble semi-natural plant communities. Despite the value of being able to predict the long-term success of such habitat...
Intensification of agricultural practices is an important factor responsible for the decline of duck populations throughout North America. More than 200 islands covering a total of 5000 ha are found in the St. Lawrence river between Montreal and Trois-Rivieres in southern Quebec. The value of...
In order to determine the significance of field margins for the overwintering of arthropods in agricultural landscapes, different sites of an integrated and of an organically managed farm were investigated in the northwest of Switzerland. During December 1995 and January 1996, soil samples were...
The floristic composition of the established vegetation and the soil seed bank in seven herbaceous communities under different traditional management regimes were compared in the Valdeón valley (Picos de Europa, Spain), a valley chosen for study because of its high diversity and non-dominance of...
Land degradation and poverty caused by traditional arable agriculture have been serious problems in the ecologically fragile and economically backward mountains of Nepal. There is a prospect to address both of these problems to some extent by promoting livestock raising. However, a large...
In 1995, an unprecedented rice blast epidemic (caused by Pyricularia grisea ) occurred in Bhutan in mostly traditional cultivars in the high (1800–2600 m) and some parts of mid altitude (1200–1800 m) agroecological zones. Possible causes of the outbreak such as introduction of a new pathogen...
The persistence of herbicides applied in vineyards has become a concern in recent years due to their wide use. Investigations into the fate of herbicides in a vineyard in the Barossa Valley, South Australia, have been directed towards the dissipation of herbicides in soil and on grapes....
In the semi-arid part of northern Tanzania, the native tropical woodland is undergoing a rapid conversion into agricultural land. This has resulted in drastic ecological changes in the region. This study was undertaken to investigate the effects of these changes in land use systems on the amount...
