Currently, China’s forest ecosystem focus is shifting from a single management objective to multiple objectives, aiming improve quality and maximize the benefits of services. Many difficulties problems are encountered in long-term development most northern state-owned farms—for example, fragmentation degradation landscapes caused by poor extensive land use—resulting an that unable provide optim...

Post-mining restoration sites often develop novel ecosystems as soil conditions are completely new and ecosystem assemblage can be spontaneous even on afforested sites. This study presents results from long-term monitoring and evaluation of an afforested oil-shale quarry in Estonia. The study is based on chronosequence data of soil and vegetation and comparisons are made to similar forest site-...

In this work, we presented the strategies and techniques that we have developed for predicting the near-future churners and win-backs for a telecom company. On a large-scale and real-world database containing customer profiles and some transaction data from a telecom company, we first analyzed the data schema, developed feature computation strategies and then extracted a large set of relevant f...

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...

Tropical forest habitat continues to decline globally, with serious negative consequences for environmental sustainability. The small mountain country of Nepal provides an excellent context in which to examine trajectories of forest-cover change. Despite having experienced large-scale forest clearing in the past, significant reforestation has taken place in recent years. The range of biophysica...

The national forest sector: context and issues Productive closed forests on drained land in Cameroon cover about 17.5 million hectares (Eba’a Atyi 1998). A zoning plan drafted in 1993 divided the national territory into a permanent forest domain (PFD) and a non-permanent forest domain (NPFD). The bulk of annual timber production is harvested in about 100 Forest Management Units (FMU) inside the...
