    Ecosystem services are substantial elements for human society. The central challenge to meet the human needs from ecosystems while sustain the Earth’s life support systems makes it urgent to enhance efficient natural resource management for sustainable ecological and socioeconomic development. Trade-off analysis of ecosystem services can

    A large number of countries recognize the role of forests in carbon sequestration and committed in their NDCs to protect forests, reduce deforestation rates, and restore forestlands. Few NDCs, however, make any specific commitments to how their forests will be protected or restored on degraded land. It is still unclear if governments will protect forests by expanding the protected estate, improving the management of existing national parks, helping communities safeguard the forests on their lands, or by taking other measures.

    Éthiopie

    The Government of Ethiopia and more specifically, the Rural Land Administration and Use Directorate, (RLAUD) has identified land use planning as an important tool for the sustainable development of the country. Land use planning is vital for optimising the use of the land and for reconciling conflicts between different land uses. Land use planning should be carried out at different levels – from national to regional to local including community: these different levels should support and integrate with each other.

    Resilience-building planning in drylands requires a participatory, integrated approach that incorporates issues of scale (often large scale) and the interconnectedness of dryland ecological and social systems. In an often political environment that supports small, “manageable” administrative units and the decentralisation of power and resources to them, planning at large scale is particularly challenging; development agents in particular may find it difficult to work across administrative boundaries and/or collaboratively.

    Land resources are one of nature’s most precious gifts. They feed us and help our societies and economies to thrive. Land resources are one of nature’s most precious gifts. They feed us and help our societies and economies to thrive. Some 2.5 billion agricultural smallholders worldwide manage around 500 million small farms, providing more than 80 per cent of food consumed in Asia and Sub-Saharan Africa. These resources are being degraded at an alarming pace.

    This chapter sets out to present a short review of (i) the general context of land degradation under the framework of UNCCD – the international convention on desertification with a specific focus on Land Degradation Neutrality, and (ii) examples of the main processes responsible for soil degradation (e.g. surface crusting, runoff and water erosion, tillage erosion, wind erosion, and salinization), along with the principles of desertification control and land rehabilitation, in light of the socioeconomic context and ecological conditions and processes.

    Algérie, Maroc, Tunisie

    States of ecological maturity and temporal trends of drylands in Morocco, Algeria and Tunisia north of 28 N are reported for 1998–2008. The input data were Normalized Difference Vegetation Index databases and corresponding climate fields, at a spatial resolution of 1 km and a temporal resolution of one month. States convey opposing dynamics of human exploitation and ecological succession. They were identified synchronically for the full period by comparing each location to all other locations in the study area under equivalent aridity.

    The eradication of hunger and poverty largely depend on how people, communities and others gain access to land. The livelihoods of many, particularly the rural poor including women, are based on secure and equitable access to and control over land and other natural resources. Land is a source of food and shelter; the basis for social, cultural and religious practices; and a central factor in economic growth.

    Land take, or the change from non-artificial to artificial land cover, reflects on-going and often conflicting claims on land. Some of the land that is 'taken' for urban development is covered with an impervious surface, which severely hampers ecosystem functioning and the related delivery of ecosystem services.
