Afrique orientale, République-Unie de Tanzanie
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.

Afrique septentrionale, Égypte
The overall aim of the project is to identify physical and institutional interventions to improve water management using an integrated approach across scales (from farm to main canal levels) and encompassing water quantity–quality interactions. The project’s geographical focus is the Nile Delta in Egypt.
The project was originally planned for four years. Due to a policy change announced by the Australian Government in reducing the aid investment in the Middle East and North Africa, including Egypt, the duration of the project was reduced to three years.

Malawi, Afrique orientale
According to the Malawi Land Act of 1965, three categories of land tenure exist in the country. These are private, public and customary land. Private land is all land held under a freehold title, a leasehold title or land registered under the Registered Land Act of 1967. Public land is all land occupied by the government while customary land is all land held, occupied or used under customary law (Peters & Kambewa, 2007; Kishindo, 1994:57).

The year 2015 will be remembered for the waves of refugees from the Middle East and North Africa (MENA) region looking for a safer future in other parts of the world. While millions of people crossed into Europe, the international community looked for the roots causes of the migration, recognizing that food insecurity, unemployment, drought and environmental degradation all play a role in the uprising and coalescing of conflict.

Asie central, Ouzbékistan
Agricultural production systems are a vital lifeline of the rural farming community in Central Asia. However, shrinking natural resource base, increased land degradation and severe irrigation water scarcity render current crop production practices not sustainable as these perform below their potential. Though there is considerable scope for improving productivity through bridging the yield gaps and introducing sustainable land management practices. However crop productivity and production pattern varies across scales, mostly driven by irrigation water availability, markets, and

Asie central, Kazakhstan, Kirghizistan, Tadjikistan, Turkménistan, Ouzbékistan
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

Afrique orientale, Éthiopie
Teff, Eragrostis tef /zucc./ Trotter is one of the most important cereal crops in Ethiopia that occupies (32%), the largest cultivated area under cereals and 26% of the whole area cultivated to annual field crops by covering about two million hectares of land annually. Tef is adapted to environments ranging from drought stress to water logged soil conditions. It can be grown at altitude ranging from sea level to 3000m above sea level, with the maximum production occurs between 1700 and 2400m.

Afrique septentrionale, Algérie, Maroc, Tunisie, Amérique du Sud, Brésil
Around 2.5 billion people – 30 percent of the world’s population – live in the dry areas, which cover more than 40 percent of the world’s land surface. Scarce natural resources, land degradation and frequent droughts severely challenge food production in these areas. Both North Africa (Morocco, Algeria, Tunisia) and the North East of Brazil fall under arid and semi-arid climate. Cacti have developed phenological, physiological and structural adaptations for growth and survival in arid environments where they have multiple functions (food, feed, soil conservation, etc.).

Viet Nam, Asia du sud-est
Assessment of future multiple ecosystem services driven by alternative land-use policies is
useful for supporting decisions about what and where to invest for the best overall environmental and
developmental outcomes. The task faces a great challenge due to the inherent complexity of humanlandscape
systems and trade-offs between rural livelihood improvement, biodiversity conservation and
carbon sequestration. Agent-based system models have been recognized to be well suited to simulate

With around one third of the world’s arable land degraded, estimated annual losses of 6.3 to 10.6 USD trillion, and a projected need to increase food production from land by 70 per cent by 2050, we simply cannot afford to neglect the loss of potential production from careless land management. Whenever land is not producing at its potential,it is an under-performing asset that requires investments to ensure the future supply chains that many industries depend upon.
