Disturbance and deforestation have profound ecological and socioeconomic effects on tropical forests, but their diffuse patterns are difficult to detect and quantify at regional scales. We expanded the Carnegie forest damage detection system to show that, between 1999 and 2005, disturbance and deforestation rates throughout the Peruvian Amazon averaged 632 square kilometers per year and 645 squ...

We present an energy-efficient wireless sensor network (WSN) architecture tailored for illegal deforestation detection. Illegal deforestation is a world-wide problem which may be prevented through improved monitoring of forested areas utilizing sensor networks equipped with chain-saw detection. Additional to detection, we identify sound source localization and sensor node localization as essent...

Much attention has been given to the call-by-value continuation passing style (CBV CPS) translation as a tool in partial evaluation, but the call-by-name (CBN) CPS translation has not been investigated. We undertake a systematic investigation of the eeect of CBN CPS in connection with partial evaluation and deforestation. First, we give an example where CBN CPS translation acts as a binding tim...

Humans have transformed Europe’s landscapes since the establishment of the first agricultural societies in the mid-Holocene. The most important anthropogenic alteration of the natural environment was the clearing of forests to establish cropland and pasture, and the exploitation of forests for fuel wood and construction materials. While the archaeological and paleoecological record documents th...

[1] The effects of natural and anthropogenic forcings (solar activity, volcanism, atmospheric CO2 concentration, deforestation) on climate changes are estimated with the Earth system model of intermediate complexity, CLIMBER2, for the past millennium. Simulated surface air temperatures for the Northern Hemisphere from the combined forcing correlate reasonably well with paleoclimatic data (r = 0...

There is a concern about the increasing pressure over the forest as economic growth increases. As for the Brazilian Amazon deforestation, there are noticeable intra-regional differences due to its occupation history, extensive area, economic structure and geographical aspects, inducing a strong spatial heterogeneity in this environmental phenomenon. This paper investigates locally the Environme...

This paper investigates the direct and indirect impacts of ethanol production on land use, deforestation and food production. A partial equilibrium model of a national economy with two sectors and two regions, one of which includes a residual forest, is developed. It analyses how an exogenous increase in the ethanol price a ects input allocation (land and labor) between sectors (energy crop and...

Avoided deforestation (AD) is a hot topic in climate change circles, including the United Nations Framework Convention on Climate Change (UNFCCC). Using financial incentives to reduce rates of deforestation and forest degradation in tropical countries has much to commend it, as deforestation is a major contributor to climate change. It might also offer additional benefits, such as protecting bi...

Deforestation is one of the world’s greatest land-use habitat alterations (Scarsbrook and Halliday, 1999). Specifically, tropical environments, where the rate of deforestation is currently increasing and changing not only the landscape, but the quality of water draining it, are the sites for the greatest freshwater biodiversity loss and system simplification (Boyero and Bailey, 2001). For examp...

The preservation of the world’s rain forests is one of the major environmental challenges of our generation. Rain forests are home to a large portion of the world’s biodiversity, and play a major role in climate regulation and in the hydrological cycle of the Earth. Despite their biological richness and ecological importance, most of the world’s rain forests are under increasing pressure of def...
