Africa has been at the centre of a "land grab" in recent years, with investors lured by projections of rising food prices, growing demand for "green" energy, and cheap land and water rights. But such land is often also used or claimed through custom by communities. What does this mean for Africa? In what ways are rural people's lives and livelihoods being transformed as a result? And who will control its land and agricultural futures?

Arid, semi-arid and dry sub-humid areas cover 61 % of Tanzania (United Republic of Tanzania, 1999) and, over the past decades, several restoration projects have worked toward reversing degradation in these areas (Kikula, 1999; Kisanga et al., 1999). These projects have addressed from social and ecological perspectives and have spanned for decades, thereby allowing for a genuine opportunity to identify and articulate lessons learned and develop good practice guidelines for restoring productive capacity of drylands.

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

Dryland (arid and semi-arid) ecosystems occupy more than 41% of global land area and are home to 2.5 billion people. More than 50% of South Asia’s dryland ecosystems are located in India. Drylands contribute about 40% of the total food grain production and support two thirds of livestock population. Despite these important roles, agricultural production systems in the drylands are facing numerous challenges that threaten their resilience and future sustainability. This paper demonstrates some of the challenges and draws implications for priorities research and strategies.

The second phase of the Sustainable Management of Marginal Drylands (SUMAMAD-2) project began in 2009 following a preparatory meeting on the project held on 3–6 June 2008 in Amman and the Dana Biosphere Reserve, Jordan, and was hosted by the Royal Society for the Conservation of Nature (RSCN). The extended SUMAMAD-2 to other world regions included South America (Bolivia) and Africa (Burkina Faso).

The conference reviewed the current state-of-knowledge of dryland ecosystems; it identified important knowledge gaps for defining future paths of research into drylands; and it commemorated fifty years of dryland research in the UN system in the context of the International Year of Deserts and Desertification. The conference - in a cross-cutting manner - also addressed issues related to research and science needed for dryland conservation, policy options for sustainable dryland development, and necessary interventions and

Millennium Development Goal Number Seven is particularly concerned with the safeguarding and provision of freshwater resources to all human.beings; this is a major challenge – and perhaps even the main challenge – for all the world’s drylands. SUMAMAD project aims at the sustainable management of marginal drylands, where the scarcity of water imposes restrictions for the productivity of each particular ecosystem. It is needed therefore to look into the entire water complex so as to promote a wise and sustainable water use. However,

As marginal drylands, all project sites share similar environmental constraints such as recurrent droughts,
water shortages, shallow soils and the threat of land degradation. As they occur in different economic,
political, social and cultural environments, it will be interesting to address similar bio-physical problems
from different perspectives stemming from varying anthropogenic factors. More importantly, the

The paper focuses on the need to rethink conventional wisdom on land tenure approaches and asks how we can best respond to the land tenure problems. It provides a comparative overview of land tenure systems in the drylands, identifies challenges and trends in land tenure reform projects, and offers ideas for decision-makers

Desertification occurs in drylands,which span a third of the earth ’s land surface in over 110 countries.It influences the lives of about 500 000 people – the so-called environmental refugees –including many of the world ’s poorest and most marginalized populations. Each year 12 million hectares (ha)are lost to deserts.That is enough land to grow 20 million tonnes of grain.

Soil erosion is a major problem in the Yellow River Basin: the river is one of the most

sediment-laden in the world. Although there is a rainfall gradient from 750 mm in southern

Shandong, to 200mm per year in northern Ningxia, most of the rainfed cropping area is in

regions with more than 400 mm per year – it is here that the project concentrated.

Conservation agriculture (featuring reduced or zero tillage, mulch retention, crop rotations

and cover crops) offers a possible solution to problems of soil erosion and low crop
