Reforestation measures for degraded lands, strategies for the sustainable management of forest resources, and agroforestry practices that incorporate trees into farming systems are increasingly demonstrating their promise for producing commercialized tree products.
In November 2011 the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) held its first Independent Science Panel meeting in Colombia.
The impact of land use and cover change on soil quality and pasture production was investigated
in the rangelands of Nakasongola District, Uganda, Landsat (TM) images of 1986 and 1990 and
Landsat (ETM+) of 2000 and 2004 for Nakasongola District were used to determine the extent
and patterns of land use and cover change using the Integrated Land and Water Information
Being able to access, control, and own productive assets such as land, labor, finance, and social capital enables people to create stable and productive lives.
Land is defined as a system engaged in generating biological productivity. It is the earth’s infrastructure for life. The rate and quality of production generated from the land depends on its major components, soil and its fertility. Soil organic matter, derived from the vegetation supported by a particular soil, is the major component that controls soil fertility.
Les terres3 peutvent se définir comme un système destiné à générer de la productivité biologique. C’est l’infrastructure naturelle qui supporte la vie sur la planète. La quantité et la qualité de cette production dépendent du principal composant de la terre : le sol et sa fertilité.
La tierra se define como un sistema bioproductivo. Es la infraestructura terrestre para la vida. La tasa y la calidad de la producción generada por la tierra dependen de sus principales componentes, de los suelos y de su fertilidad. La materia orgánica del suelo, derivada de la vegetación que crece en un suelo determinado, es el principal componente que controla la fertilidad de éste.

Despite challenges in many river
basins, overall the planet has
enough water to meet the full range
of peoples’ and ecosystems’ needs
for the foreseeable future, but
equity will only be achieved through
judicious and creative management.
