TL;DR: In this paper, the effects of forest management on soil erosion in Southeast Asia, clear distinctions must be made between surface erosion and landslide processes, which are episodic processes triggered by individual rainfall events or artificial inputs of water; slower, deep-seated landslides initiate or activate after a longerterm accumulation of water.

TL;DR: A meta-analysis of land-cover transformations of the past 10-15 years in tropical forest-agriculture frontiers world-wide shows that swidden agriculture decreases in landscapes with access to local, national and international markets that encourage cattle production and cash cropping, including bio-fuels.

TL;DR: By 2050, the area of land dedicated to rubber and other diversified farming systems could more than double or triple, largely by replacing lands now occupied by evergreen broadleaf trees and swidden-related secondary vegetation.

TL;DR: In this article, the authors map global annual urban dynamics from 1985 to 2015 at a 30'm resolution using numerous surface reflectance data from Landsat satellites and find that global urban extent has expanded by 9,687'km2 per year.

TL;DR: In this article, the authors analyzed the subsequent spread of rubber between 2005 and 2010 in combination with environmental data and reports on rubber plantation performance and showed that rubber has been planted into increasingly sub-optimal environments.
