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. One management option is utilizing rainfall more efficiently through water harvesting. In arid areas, different types of water harvesting techniques (WHT) are being developed by

The Kelka forest in the Mopti region of Mali is important for the provision of ecosystem services like carbon sequestration and maintenance of the hydrological cycle. The Kelka forest area occupies more than 300, 000 hectares with 15
villages within and around its boundaries. The forest resources and soil fertility of the forest are in continuous decline due to a combination of climatic and human induced factors. For example, the availability of firewood has halved -

Gedaref State was previously known as the
food basket of Sudan. Over several decades
unsustainable agricultural practices that
combined near-monocropping with low nutrient
replenishment have led to significant degradation
of soils, which are no longer able to sustain farmer
livelihoods. This study found that adopting
an integrated sustainable land use and forest
restoration scenario could reverse the current
land degradation trend. The integration of Acacia
senegal with sorghum, Sudan’s primary staple -

This research was carried out in three agro-climatic regions of Mali (Mopti, Koulikoro and Sikasso) to assess
contour bunding technology (CBT) for improved land and water management. Reference was made to
existing literature and field surveys were conducted following georeferencing and quantification of existing
land and water management technologies. Farmers’ perceptions towards the use of the most commonly
applied technologies were assessed. Results indicate that CBT is widely adopted in farmers’ fields to -

Land degradation is a pressing concern that reaches
across all republics of Central Asia and is increasingly
affecting the economy and quality of life in each.
The resulting loss of arable land particularly affects
the rural poor, who depend directly on what
the land can provide for their very survival and
livelihoods. The breakup of the Soviet Union led to
mass de-collectivisation of agricultural frameworks
across Central Asia, with formerly centralised land
management regimes dissolved. The reorganisation -

Land degradation is a serious problem, particularly on vulnerable agricultural lands to soil erosion, which
signifies the temporary or permanent decline in the productive capacity of the land (UN/FAO definition).
Erosion is one of the most common problems around the world. Sanders (2004) considers that erosion
and soil degradation issues have contributed to the decline of great civilizations in Egypt, China or
Greece. The annual costs of soil erosion in the US are estimated between US$ 30 billion and US$ 44 -

The threat that the degradation of terraces in the highlands of Yemen poses to the livelihood of rural households and to national economic development has been widely recognized. The aim of this study was to contribute to the development of policy recommendations for the improvement of the life of rural families in the Yemeni mountains. Three small mountain watersheds (200-700 ha) in the northern, middle and southern mountain regions of Yemen were selected as the testing grounds for this study.

Many efforts have been invested in the Dry Areas to combat land degradation and desertification. Different strategies and approaches for conserving soil and water and restoring degraded lands have been developed by local, national and international agents to synergise efforts towards land degradation neutrality achievement. Tunisia is a dryland country facing a high risk of land degradation over more than 50% of its territory. It is a country with high investment programs for soil and water conservation (SWC), and large level adoption of SLM practices.
