Tropical forests are now at the center stage of climate mitigation policies worldwide given their roles as sources of carbon emissions resulting from deforestation and forest degradation. Although the international community has created mechanisms such as REDD+ to reduce those emissions, developing tropical countries continue to invest in infrastructure development in an effort to spur economic...

OBJECTIVES To assess the global amount of forest and woodland consumed annually for curing tobacco between 1990 and 1995; to estimate tobacco's share in total deforestation; to rank tobacco-growing countries by the degree of impact of tobacco deforestation; and to indicate environmental criticality emerging from tobacco's impact on forest resources. DESIGN Production of country-specific estim...

We completed a meta-analysis of regional and global climate model simulations (n=96) of the impact of Amazonian deforestation on Amazon basin rainfall. Across all simulations, mean (±1σ) change in annual mean Amazon basin rainfall was 12 ± 11%. Variability in simulated rainfall was not explained by differences in model resolution or surface parameters. Across all simulations we find a negative ...

deforestation in the past decades has risen. so, the proper development of human activities in forests requires the environmental limitations to be considered during forests management process. one of the appropriate measures is the determination of ecological vulnerability. in the present study, patom district of kheyrud forest was classified based on the ecological sustainability, using objec...

Satellite images were used to determine rates of deforestation over the past 35 years and to identify current deforestation "hotspots" in the eastern rainforests and in the dry endemic forests of southern Madagascar. The analysis of population trends, topography, and coincident ethnographic research points to a number of different factors influencing deforestation in these regions. Each of thes...

Quasi-experimental methods increasingly are used to evaluate the impacts of conservation interventions by generating credible estimates of counterfactual baselines. These methods generally require large samples for statistical comparisons, presenting a challenge for evaluating innovative policies implemented within a few pioneering jurisdictions. Single jurisdictions often are studied using com...

The analysis of rapid environment changes requires orbital sensors with high frequency of data acquisition to minimize cloud interference in the study of dynamic processes such as Amazon tropical deforestation. Moreover, a medium to high spatial resolution data is required due to the nature and complexity of variables involved in the process. In this paper we describe a multiresolution multitem...

1 Summary This project aims to understand and model the social processes that contribute to large-scale deforestation in Amazonia. Biomass burning emissions associated with deforestation in the region are responsible for 74% of Brazil's greenhouse gas emissions and have an impact on global environmental changes. We argue that land changes in Amazonia are brought about by social and institutiona...

Abstract. Deforestation is associated with a decrease in slope stability through the alteration of hydrological and geotechnical conditions. As such, deforestation increases landslide activity over short, decadal timescales. However, longer timescales (0.1–10 Myr) location timing landsliding controlled by interaction between uplift fluvial incision. Yet, (human-induced) landscape evolution has ...

Abstract The Amazon is hypothesized to reach an irreversible ‘tipping point’ when deforestation slows the hydrological cycle sufficiently that tropical forest ecosystems cannot be sustained. However, inception of such a tipping point has not been supported by observations and relevant links between atmospheric moisture recycling are poorly understood. Here we show reduction in evapotranspiratio...
