TL;DR: This paper introduces urban land teleconnections as a conceptual framework that explicitly links land changes to underlying urbanization dynamics and examines several environmental “grand challenges” and discusses how the concept could help research communities frame scientific inquiries.

TL;DR: In this paper, the authors provided an analysis of trends in vegetation greenness of semi-arid areas using AVHRR GIMMS from 1981 to 2007, and found that greenness increases are found both in semi-arsid areas where precipitation is the dominating limiting factor for plant production (0.019 NDVI units) and in semiarid regions where air temperature is the primarily growth constraint (0.,013 NDVI Units).

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: In this paper, the authors present a conceptual and methodological framework that is capable of capturing the way in which a landscape is shaped and functions -part as a result of decisions taken by local agents, and partly in response to conditions created on regional to global scales.

TL;DR: In this paper , the authors focus on the rigorous and appropriate use of geospatial map products from satellite imagery and statistically sound methods for reporting area estimates and their associated uncertainty, and develop a set of standards and guidelines and how to perform rigorous map accuracy assessment.
