Success of migration in birds in part depends on habitat selection. Overall, it is still poorly known whether there is habitat selection amongst landbird migrants moving across landscapes. Europe is chiefly covered by agro-forestry mosaic landscapes, so migratory species associated to either agricultural landscapes or woodland habitats should theoretically find suitable stopover sites along mig...

Indicators of land quality (LQIs) are being developed as a means to better coordinate actions on land related issues, such as land degradation. Economic and social indicators are already in regular use to support decision making at global, national and sub-national levels and in some cases for air and water quality, but few such indicators are available to assess, monitor and evaluate changes i...

A multi-agent model of social and environmental complexity of deforestation was developed for the Caparo Forest Reserve, Venezuela. It includes three types of agents: settlers, government, and lumber concessionaires. Settlers represent people of limited economic resources that deforest and occupy reserve land to grow crops and eventually claim property rights of this land. Their agricultural pr...

At national level, numerous institutions are active in the many fields involving soil information issues, for example: Ministries of Agriculture and Environment, Agency for Environment Protection and Technical Services, university soil science departments, Experimental Institute for Soil Study and Conservation, centres of the National Research Council, as CNR-IRPI). The National Committee for S...

Since traditional cost-benefit analysis does not include environmental variables in consideration, the concept of emergy was used to measure all direct and indirect energy to produce a product. In emergy analysis, environmental, social and economic variables are included and indexes are calculated for comparison for several systems. In this paper, emergy and financial ratios are used to determi...

2 Dept. Agro Forestry Engineering– Universitat de Lleida 5 6 Abstract 7 Two different spray application methods were compared in three vine varieties at 8 different crop stages. A conventional spray application with a constant volume rate per 9 unit ground area (l·ha -1 ) was compared with a variable rate application method designed 10 to compensate electronically for measured variations in can...

The study was conducted in Adamawa State, Nigeria. The major thrust of this study is to assess the adoption rate of technology in Fadama III project, Adamawa State, Nigeria. Fadama III is being implemented in 20 Local Government Areas (LGA) of Adamawa State. In its four years of operation, Fadama III project has realized significant impact on household access to new and proven technologies. The...

Biomass and energy evaluation was carried out in the Municipality of Teresópolis Rio de Janeiro, Brazil. Th e following agricultural and natural systems were considered: (i) vegetables systems (leaf, fruit and mixed vegetables); (ii) citrus; (iii) ecological agro-forestry; (iv) cattle ranching, (v) silvopastoril systems, (vi) forest fragments and, (vii) forest in regeneration stage (1, 2 and 3 ...
