Key Messages and Recommendations
• Combating desertification and land degradation while mitigating the effects of drought can secure long-term socio-economic benefits for people living in drylands and reduce their vulnerability to climate change.
• Land degradation neutrality (LDN) is an approach that counterbalances the expected loss of productive land with the recovery of degraded areas.
• Land tenure insecurity, especially for women, often prevents farmers from adopting sustainable land management practices

In Pakistan, rangelands are the major source of feed for about 167.5 million heads of livestock. At present rangelands are being grazed by all kinds of livestock. About 40 percent of feed requirements for horses, donkeys and camels, 60 percent of the goats and sheep are met from rangelands whereas only 5-10 percent of the population of cattle and buffaloes graze in the rangelands despite they are heavily overgrazed, and has reduced the carrying capacity by 30 to 50 percent of their potential.

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

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
vulnerable and can collapse in the short term, given the right conditions and protection, these
areas also have a great potential for recovery. Examples of the recovery of areas have led to the

Research on micro-catchment rainwater harvesting techniques by ICARDA and Jordanian
scientists has led to the establishment of semicircular bunds on contour ridges and furrows
(using GPS laser-guided Vallerani machine) and runoff strips in two communities of Jordan
Badia. As an outcome of this research, an effective micro-catchment laser-guided system was
identified for rainfall harvesting, which has led to improved water availability, increased
vegetative cover and improved soil health, and provided rural communities substantial sources

This issue of Caravan chronicles ICARDA’s efforts in developing a research strategy and a need-based research program for the CAC region. In doing so, ICARDA played a major role in bringing together all partners, most importantly donors. The article on page 8 traces the history of this effort and provides an overview of the current status of collaboration.

Stipagrostis pungens is a perennial grass species which belongs to the Poaceae family. It is usually found with several erect culms, grows up to 1.5 m in height, and forms substantial tufts. It is a tall stiff glabrous grass with pungent leaves, and a C4 grass with sclerophyllous, spine-tipped, inrolled leaves, with sunken stomata. The root system extends laterally for a radius of 20 m or more. The roots are covered throughout their length by a sandy sheath, which is penetrated by the root hairs that occur throughout the entire length of the sheath.
