In recent years, this sector has had to tackle far-reaching changes taking place in the social, economic and political system. New demands are now being addressed and policies reformulated.
Knowing the influence of land use/land cover changes on the hydrological behavior of a subwatershed is essential to land use planning. The Alto Paraguaçu Watershed is a major producer of fruits and vegetables, and currently the largest producer of English potato in the north/northeast of Brazil.
The research of the landscape structure and its changes was carried out in a part of the Horná Orava region. Landscape structure was studied and compared in 2 periods (1958 and 2001). Two types of changes were identified: anthropogenic and succession.

A voluntary conservation approach may reveal environmentally minded landowners who are willing to protect their lands with a compensation that is lower than the market price based compensation.
Urban trees can potentially mitigate environmental degradation accompanying rapid urbanisation via a range of tree benefits and services. But uncertainty exists about the extent of tree benefits and services because urban trees also impose costs (e.g. asthma) and may create hazards (e.g.
Greenbelts are effective tools for mitigation of traffic induced air and noise pollution. In this study, the potential role of greenbelts along the roadside for the reduction of air pollution and noise levels has been assessed by using seasonally monitored data in a megacity of Bangladesh.
Forest fires in mountainous areas can cause severe deforestation which can potentially trigger secondary natural hazards like debris falls and avalanches. We documented an extreme case study for the range of possible post-fire land cover (LC) dynamics.
KEY MESSAGE : We compiled 2,458 biomass equations from 168 destructive sampling studies in Indonesia. Unpublished academic theses contributed the largest share of the biomass equations. The availability of the biomass equations was skewed to certain regions, forest types, and species.
