A medida que la comunidad mundial intenta abordar el tema del cambio climático a través de medidas de adaptación y mitigación en el paisaje en países en desarrollo, se realza cada vez más la importancia que reviste la tenencia de recursos.
Uno de los temas de negociación en la Convención Marco de Naciones Unidas sobre Cambio Climático (CMNUCC) que ha atraído una atención preferente de los países de América Latina es el que dice relación con la instalación de un mecanismo, dentro de este convenio internacional, que pudiera movilizar recursos financieros para hacer frente a los procesos de deforestación y degradación que ocurren en
MENA’s permanent cropland – currently at less than 6% of the total land area – is shrinking due to serious land degradation and recurrent droughts. The region faces the most severe water shortage in the world with annual renewable water resources per capita estimated to decline from 1,045 m3/yr in 1997 to 740 m3/yr in 2015.
This document is a synthesis of outcomes from a knowledge process that was a collaborative effort involving researchers, scientists, and technicians from Iran, Jordan, Morocco, Tunisia, and Yemen.
En Aisén, Chile, se compararon distintos estadios de degradación antropogénica de la vegetación arbustiva original en una serie de distintos manejos de pastoreo, utilizando los indicadores ecológicos vegetales de Ellenberg para los factores de luz, temperatura del aire y de reacción, nitrógeno y humedad del suelo. El matorral de ñirre primario se consideró como inicio de la serie.
Land degradation occurs in all continents and affects the livelihoods of millions of people, including a large proportion of
the poor in the drylands. Opuntiaficus-indica (L.) Mill. is a xerophytic cactus species, widely cultivated in arid and semi-arid regions
Brochure on "Community based Rainfed Watershed Management" project. A collective research, learning & demonstration project for increasing productivity and adapting smallholder farmers to climate change in rainfed dry areas.
T he Democratic Republic of Congo (DRC) committed to the mitigation of the effects of climate change by signing the Kyoto Protocol for climate change and other related environmental management protocols.
Climate warming and human actions both have negative impacts on the land cover of Mongolia, and are accelerating land degradation. Anthropogenic factors which intensify the land degradation process include mining, road erosion, overgrazing, agriculture soil erosion, and soil pollution, which all have direct impacts on the environment.
Land degradation is severe in the steep sloping highlands in eastern Africa; natural resource management is central to good governance and increasing enfranchisement of rural people.
Land-degradation neutral world is an aspirational goal, which was agreed at the UN Conference on Sustainable Development (Rio+20) in June 2012. To achieve this goal, land degradation should be avoided and for every hectare of degraded land a hectare of land should be restored preferably in the same ecosystem and landscape.
Drylands are complex social-ecological systems, characterized by non-linearity of causation, complex feedback loops within and between the many different social, ecological, and economic entities, and potential of regime shifts to alternative stable states as a result of thresholds. As such, dryland management faces a high level of uncertainty and unpredictability.
