Les terres arides couvrent près de la moitié de la surface terrestre et abritent un tiers de la population mondiale. Elles sont confrontées à des défis hors du commun, notamment ceux posés par la désertification, la perte de biodiversité, la pauvreté, l’insécurité alimentaire et les changements climatiques. Quelque 20 pour cent des terres arides de la planète sont dégradées, et les personnes qui vivent sur ces terres sont souvent piégées dans un cercle vicieux de pauvreté, pratiques destructrices et détérioration de l’environnement.

Soil loss is a major threat to the agricultural development in Malawi and by extension is also a major hindrance to the overall economic development of the country since the Malawian economy is dependent on agriculture. Not only does soil loss reduce the cultivable soil depth but it also takes away the fertile soils from the farmlands. The net effect is loss of agricultural productivity, increased expenditure on fertilizers, and a general decline in profitability of crop production.

Soils and climate change

Policy Papers & Briefs
сентября, 2016

Soils constitute the largest store of terrestrial carbon. When managed using Sustainable Soil Management (SSM) techniques, soils can play an important role in climate change adaptation and mitigation and could enhance the provision of ecosystem services by storing carbon (carbon sequestration) and decreasing greenhouse gas emissions in the atmosphere.

Patterns and Predictors of Recent Forest Conversion in New England

Peer-reviewed publication
сентября, 2016

New England forests provide numerous benefits to the region’s residents, but are undergoing rapid development. We used boosted regression tree analysis (BRT) to assess geographic predictors of forest loss to development between 2001 and 2011. BRT combines classification and regression trees with machine learning to generate non-parametric statistical models that can capture non-linear relationships.

Uganda’s progress in reducing poverty from 1993 to 2006 is a remarkable story of success that has been well told. The narrative of Uganda’s continued, albeit it slightly slower, progress in reducing poverty since 2006 is less familiar. This was a period in which growth slowed as the gains from reforms years earlier had been fully realized, and weak infrastructure and increasing corruption increasingly constrained private sector competitiveness (World Bank 2015). This report examines Uganda’s progress in reducing poverty, with a specific focus on the period 2006 to 2013.
