“Environmental Perception Process of Desertification in Perú”, try to do an analysis and evaluation of Peruvian territory in terms of enviromental degradation due to problems of biodiversity loss, progressive loss of productive capacity land ecosystem in the climaterelevant ecological Peruvian territory. The purpose is to know the territorial spaces with problems of environmental degradation and prevention alternatives to existing problems.

Las ciudades de la región latinoamericana se expanden incontroladamente para atender la enorme demanda social de todos los niveles de ingreso. En este proceso irreversible de crecimiento demográfico y expansión urbana, las ciudades se convierten en ávidas consumidoras de recursos naturales, principalmente agua, que después de ser utilizada es vertida en un alto porcentaje sobre cauces a cielo abierto. También son vertidos todos los desechos sólidos o basura, residuos del consumo doméstico en comidas.

La cuenca del río Kilca es uno de los principales sistemas hidrográficos de la región antecordillerana, ubicada en el centro de la provincia de Neuquén. En esta zona, de clima subhúmedo, el uso de suelo dominante es el de "veranada", que consiste en una de las tres etapas anuales de un tipo de ganadería trashumante, basado en el aprovechamiento forrajero de pastizales naturales. Dada la constitución fisiográfica de estos paisajes, existe en ellos una gran propensión al desarrollo de procesos geomorfológicos de erosión y remoción en masa.

A fines del anterior siglo los impactos ambientales negativos de las actividades humanas sobre los bosques amazo?nicos se han vuelto un tema primordial en las agendas poli?ticas mundiales. La investigacio?n cienti?fica ha permitido desarrollar una variedad de alternativas para reducir los impactos por deforestacio?n y la degradacio?n de los bosques.

Across vast areas of the world, human activity has degraded once fertile and productive land. Deforestation, overgrazing, continuous farming and poor irrigation practices have affected almost 2 billion hectares worldwide, threatening the health and livelihoods of over one billion people. In this edition of New Agriculturist, a collection of articles explores some of the approaches and policies that can help to successfully rehabilitate degraded land.

This report analyses the impact of climate change and land degradation on agriculture and related sectors in Viet Nam. It intends to guide the project based on the design of the Country Strategic Opportunities Paper (COSOP) priorities and to identify supplementary financing for International Fund for Agricultural Development (IFAD) projects from the UNFCCC and other carbon related financing mechanisms. It is explained that the harmful effects of climate change are already being experienced in Viet Nam, and farming communities have begun to respond by:

Landlocked developing countries (LLDCs) are disadvantaged in a myriad of ways and they have special needs which require special attention. Challenges such as undiversified economies, vulnerability to climate change and climate variability, land degradation and desertification, among others, are undermining the economic potential of many LLDCs. This has been exacerbated by weak export base of many LLDCs centered on a few primary agricultural and/ or mineral commodities.

Recent arguments have stated that the new livestock development policy will carry a high social cost, that the reality of range degradation in Botswana has been ignored, and that there is no basis for assuming that de-stocking would decrease the productivity of rangeland.

Traditional land tenure systems in Togo have been undermined but not destroyed by the introduction of private property and ‘modern’ tenure reform. However, confusion over land tenure issues has proved to be an obstacle to efforts to promote efficient resource management and to combat desertification.

Drylands have potential for economic activity now markets are emerging for natural products such as aloe or gum Arabic. However it is difficult to take advantage of these opportunities because there is a lack of structure for this market. A regulatory framework providing an enabling environment for increasing investment in the sustainable use and management of land and natural resources would be beneficial.

This article suggests that communual rangeland management policies in Botswana and Zimbabwe are based on incorrect technical assumptions about the stability of semiarid rangelands, the nature of rangeland degradation, and the benefits of destocking. Consequently, inappropriate policies, stressing the need to destock and stabilise the rangelands, are pursued.Acknowledgement of the great instability but intrinsic resilience of rangeland would encourage the Governments to more favourable regard the opportunistic stocking strategies of the agro-pastoralists of the Communual Areas.

The report focuses on: the statue of land degradation: types of degradation, their nature, severity and extent; the causes and consequences of land degradation; institutions to combat land degradation; proposals for strengthening efforts to combat land degradation. Countries covered are: Afghanistan; Bangladesh; India; Bhutan; Iran; Pakistan; Nepal; Sri Lanka.
