Sawang District in North Aceh Regency, has a large forest area. During the sustained conflict Aceh, most of areas were degraded and greatly affected destruction ecosystem. The citronella plants on reforestation land have high potential to be developed as intercropping plant because economic value could cultivated during 5-7 years. research is located Riseh Tunong Village, District, Aceh. This w...

Soil erosion/sedimentation is an immense problem that has threatened water resources development in the Nile river basin, particularly in the Eastern Nile (Ethiopia, Sudan and Egypt). An insight into soil erosion/sedimentation mechanisms and mitigation methods plays an imperative role for the sustainable water resources development in the region. This paper presents daily sediment yield simulat...

The Elbe-DSS is a tool for integrated river basin management of the German part of River Elbe basin. Various simulation models are used to assess the impact of measures such as reforestation, changes of agro-practices or efficiency of wastewater treatment plants and of external scenarios on a set of management objectives. For the assessment of nutrient and pollutant loads and impacts, MONERIS a...

Concerns have been raised among the scientific communities about the increased atmospheric concentration of carbon dioxide (CO2). Carbon sequestration rates can be maintained or increased by afforestation, reforestation, avoided deforestation, forest preservation and particular tending and cultural operations on existing forests. Of these, afforestation and reforestation are the only eligible p...

An important criticism of bioclimate envelope models is that many wide-ranging species consist of locally adapted populations that may all lag behind their optimal climate habitat under climate change, and thus should be modeled separately. Here, we apply a bioclimate envelope model that tracks habitat of individual populations to estimate adaptational lags for 15 wide-ranging forest tree speci...

The historical area of bottomland hardwood forest in the Mississippi Alluvial Valley has been reduced by >75%. Agricultural production was the primary motivator for deforestation; hence, clearing deliberately targeted higher and drier sites. Remaining forests are highly fragmented and hydrologically altered, with larger forest fragments subject to greater inundation, which has negatively affect...

Six Earth system models of intermediate complexity that are able to simulate interaction between atmosphere, ocean, and land surface, were forced with a scenario of land cover changes during the lastmillennium. In response to historical deforestation of about 18 million sq km, themodels simulate a decrease in globalmean annual temperature in the range of 0.13–0.25 C. The rate of this cooling ac...
