Conservation Agriculture (CA) is increasingly promoted in Africa as an alternative for coping with the need to increase food production on the basis of more sustainable farming practices. CA is specifically seen as a way to address the problems of soil degradation resulting from agricultural practices that deplete the organic matter and nutrient content of the soil. It aims at higher crop yields and lower production costs. Yet, success with adopting CA on farms in Africa has been limited (Kassam et al., 2009).

With current rates of land degradation reaching
ten to twelve million ha per year, there is an
urgent need to scale up and out successful,
profitable and resource-efficient sustainable
land management practices to maintain the
health and resilience of the land that humans
depend on. As much as 500 million out of
two billion ha of degraded land, mainly in
developing countries, have restoration potential,
offering an immediate target for restoration
and rehabilitation initiatives.1 In the past, -

This report provides evidence of how increasingly
scarce resources can be conserved, and also
presents tools for policy-/decision-makers to
promote and secure future wealth and human wellbeing
through sustainable land management. It
emphasises taking long-term benefits into account
and focuses on practical solutions, as well as the
context in which sustainable land management
occurs. The report aims to ensure the returns of
sustainable land management (e.g., economic
growth, food security, sustainable livelihoods and -

Paddy rice agriculture affects food supply, climate, water, biodiversity, and ecosystems. It varies substantially over time and space, for example, continuous expansion in northeastern China and rapid loss in southern China in the past decades. However, no maps at fine spatial resolution (e.g., 30-m) are available to document and illustrate the spatial patterns and temporal dynamics of paddy rice planting areas in China.

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 -

Rangelands are the mainstay of pastoral livelihoods worldwide. Within rangelands, there are landscape depressions or lowlands characterized by high production potentials with their unique edaphic and hydrologic properties. The purpose of this ongoing research is to evaluate the effect of grazing exclusion on the vegetation characteristics and plant community structure in the arid lowland pastoral ecosystems. Plots were randomly identified within two distinct lowlands in Majidya and Sabha, in the Jordanian Badia.

Despite their ecological, economic and social importance, Mediterranean grasslands continue to receive limited scientific, political and media attention. Grasslands are typically viewed as underutilized space, able to be transformed into more “valuable” land by placing it under cultivation, transforming it into forest land and/or privatizing it. This paper synthesizes a number of pertinent issues in relation to social and economic systems on grasslands within the southern Mediterranean region.

The concern for the well-being of land is often directly related to one’s proximity to the land, be it physically, economically or culturally. Land is more precious if one’s livelihood depend on it immediately than if one is merely a visitor. Land is valued differently if it is the base of one’s power or wealth than if one’s community is in need of its integrity and depends on the ecosystem services (ESS) that it provides. To some extent, this may explain the great challenge UNCCD has experienced in mustering international support for its mandate.
