Dégradation et Régime des Terres

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.

Drylands are characterized by physical water scarcity, often associated with land degradation and
desertifi cation. Other factors that contribute to these problems include high population densities,
unwise agricultural practices and overgrazing. However, while desert ecosystems are fragile and

El presente trabajo busca hacer una lectura estructural de algunas de las dinámicas agrarias y rurales de las últimas décadas en Guatemala, Honduras, El Salvador y Nicaragua.

La degradación de la tierra se está acelerando, y las sequías van en aumento en todo el mundo. En la conferencia Río+20, los dirigentes mundiales reconocieron sin ambages que la desertificación, la degradación de la tierra y la sequía son problemas de dimensión mundial que afectan al desarrollo sostenible de todos los países, en particular los que están en desarrollo.

Ethiopia has great agricultural potential as it has vast area of fertile land, diverse climate, sufficient annual rainfall, & abundant labor force. However, the current performance of agric.

Water scarcity and land degradation are widespread problems that affect agricultural productivity, food security and environmental quality in several parts of the world, particularly in the dry areas. Sustainable management of soil and water is necessary to optimize the use of limited rainwater for crop production and to decrease soil erosion.

Las ciudades de la región latinoamericana se expanden incontroladamente para atender la enorme demanda social de todos los niveles de ingreso.

This brief is intended to inform government decision makers, agencies and specialist groups involved in rural development and revenue generation activities for communities and women

La desertificación/degradación de la tierra raramente está considerada como un tema económico, y la sequía rara vez como un desastre. Dado que la desertificación, la degradación de la tierra y la sequía son procesos lentos y sigilosos, su avance es subrepticio, y nos inducen a subestimar sus efectos socioeconómicos.

This publication is a baseline assessment reviewing the current knowledge of land degradation in the rangelands of Jordan - known as Badia - with a special focus on its causes. It includes a review of current legislation and on-going initiatives to combat land degradation, along with an analysis of the main constraints limiting their effectiveness.

The UNEP foresight report contains a description of the 21 emerging environmental issues identified through the UNEP Foresight Process.

This report suggests that a new and explicit goal of sustainable development to be agreed as a result of Rio+20 should be the reduction of the rate of land degradation to achieve land degradation neutrality, which we refer to as “Zero Net Land Degradation” or ZNLD.
