Gender and desertification

Policy Papers & Briefs
декабря, 2011
Global

The range of measures often emphasized in gendered efforts to reverse desertification and land degradation and mitigate the effects of drought (DLDD) include improving the participation of women in decision-making, building the capacity of women’s organizations, eliminating illiteracy among women, minimizing the heavy workload on women and eliminating gender disparities in employment and in the access to and ownership of resources. This fact sheet draws attention to the complex and evolving nature of gender issues pertaining to drylands women.

Parmi l’éventail des mesures souvent mises en avant dans l’approche genre dans le cadre de la lutte contre la désertification, la dégradation des terres et de l’atténuation des effets de la sécheresse, figurent l’amélioration de la participation des femmes à la prise de décision, le renforcement des capacités des organisations féminines, l’élimination de l’illettrisme féminin, l’allègement de la charge de travail des femmes et l’élimination des disparités hommes-femmes au travail, dans l’accès aux ressources et à la propriété.

El conjunto de medidas a menudo señaladas desde la perspectiva de género para revocar la desertificación y la degradación de las tierras y atenuar los efectos de la sequía (DLDD) incluye: la mejora de la participación de las mujeres en la toma de decisiones, la creación de capacidad de las organizaciones de mujeres, la erradicación del analfabetismo femenino, la disminución de su carga de trabajo y la desaparición de las disparidades de género, tanto en el trabajo como en el acceso y posesión de recursos.

Attention to land degradation and environmental pollution has increased significantly in the past 25 years, largely due to greater levels of international cooperation and recognition that local changes in land resources have global impacts. As the world’s focus on climate change increases, so, too, does the attention being paid to drought and its rise in frequency and severity.

Experiences in monitoring and assessment of sustainable land management

Journal Articles & Books
декабря, 2011

Although sustainable land management (SLM) is widely promoted to prevent and mitigate land degradation and desertification, its monitoring and assessment (M&A) has received much less attention. This paper compiles methodological approaches which to date have been little reported in the literature. It draws lessons from these experiences and identifies common elements and future pathways as a basis for a global approach. The paper starts with local level methods where the World Overview of Conservation Approaches and Technologies (WOCAT) framework catalogues SLM case studies.

Variation in structural and physiological leaf traits of eight species in karst desertification area of China

Leaf traits have long been recognized as influential factors in the acquisition and processing of resources by plants. However, there is less knowledge of between-species variations in seasonal changes in leaf traits and trait interrelationships. Therefore, we examined variations in leaf area (LA), dry biomass (DM), specific leaf area (SLA), and leaf gas-exchange parameters in one non-native and seven native tree species under field environmental conditions, in a karst area in China subjected to desertification. Measurements were taken three times during the growing season.

Agricultural Development and Associated Environmental and Ethical Issues in South Asia

Southern Asia

South Asia is one of the most densely populated regions of the world, where despite a slow growth, agriculture remains the backbone of rural economy as it employs one half to over 90 percent of the labor force. Both extensive and intensive policy measures for agriculture development to feed the massive population of the region have resulted in land degradation and desertification, water scarcity, pollution from agrochemicals, and loss of agricultural biodiversity.

Object-based gully feature extraction using high spatial resolution imagery

Journal Articles & Books

Morocco

Gully erosion is responsible for a substantial amount of soil loss and is generally considered an indicator of desertification. Hence, mapping these gully features provides essential information needed on sediment production, identification of vulnerable areas for gully formation, land degradation, and environmental and socio-economical effects.

Differential field response of two Mediterranean tree species to inputs of sewage sludge at the seedling stage

Journal Articles & Books
декабря, 2011

Land degradation and desertification is a common feature in Mediterranean landscapes due to extensive and intensive land use and natural or man induced disturbances. The ecosystem may need external inputs to recover its composition and function as soils are often impoverished and vegetal key stone species lost. We evaluated the effects of the application of fresh and air-dried biosolids in the establishment and morphological and physiological performance of seedlings of Pinus halepensis and Quercus ilex under dry Mediterranean field conditions.

Desertification in China's Horquin area: a multi-temporal land use change analysis

Journal Articles & Books
декабря, 2011
China

China's Horquin area in the northern farming–pastoral transition zone is undergoing rapid land degradation and rangeland modification that is impacting far broader areas as the source of material for dust storms. Multi-temporal Landsat images of the Horquin core area were used to generate a time series of land use covering about a 30-year period, 1975–2003. We show that the physical environment in Horquin deteriorated between 1975 and 2000, although this situation was more controlled after 2000.

Mapping erosion susceptibility by a multivariate statistical method: A case study from the Ayvalık region, NW Turkey

Turkey

Erosion is one of the most important natural hazard phenomena in the world, and it poses a significant threat to Turkey in terms of land degredation and desertification. To cope with this problem, we must determine which areas are erosion-prone. Many studies have been carried out and different models and methods have been used to this end. In this study, we used a logistic regression to prepare an erosion susceptibility map for the Ayvalık region in Balıkesir (NW Turkey).

social and environmental challenges faced by goat and small livestock local activities: Present contribution of research-development and stakes for the future

Small livestock (goats, sheep, llamas, camels…) like other agricultural activities could have to face dramatic social, economical and environmental challenges. These challenges are identified underlining that these activities are often important and well present in countries with low incomes or in less favored areas. Although they are often low input production systems with lower environmental impacts, they face desertification and less water availability, genetic erosion, soil degradation and degradation of rangelands, competitions for land use.
