    The countries in North Africa share an arid and semi-arid environment with high diversity: mountainous areas run alongside maritime areas and desert. Currently, urban dwellers in North Africa represent more than 50% of the population and are expected to be more than 60% by 2030. However, the urban system in North Africa is suffering urban primacy. The region is well known for its endowment in mineral deposits such as oil and gas. However, it is also known for being one of the poorest regions in the world in water resources.

    For over a decade, the globalisation of environmental, economic and social issues has induced rapid modification in agriculture and land. These changes raise the question of future extensive livestock systems in regards to the worldwide challenge to double livestock production by 2050 in ways which are safe for the environment. In order to better understand and follow modification processes, a comparative study of livestock systems and land dynamics has been carried out on seven case studies on three continents through the use of a common grid.

    We propose a flexible and adaptable framework to assist the quick design of models dealing with the durability of the extensive livestock systems at the territorial scale. This metamodel results from the collaborative design starting from MAS developed on 7 sites in Latin America, France and Senegal. It is composed of four packages: Agent, Community, Space and Vegetation-Herd. We illustrate these packages with examples extracted from the various models. The role of this tool is discussed in order to show its advantages and its limits

    Boom-and-bust cycles are commonplace in the exploitation history of sea cucumber fisheries but pandemic overfishing to critical levels now threatens the persistence of breeding stocks for future generations of coastal fishers. Resource managers must embrace an ecosystem approach to fisheries, in which biodiversity conservation, ecosystem services and the concerns of stakeholders are taken into account alongside of the productivity of stocks and the economic gains from fishing. This document is an abridged version of FAO Fisheries and Aquaculture Technical Paper No.

    The impacts of natural disasters such as hurricanes, floods, earthquakes and tsunamis have been increasing steadily since the 1950’s, particularly for developing countries. According to a World Bank external evaluation report “natural disasters destroyed US$652 billion in property worldwide in the 1990s alone – an amount 15 times higher in real terms compared to the 1950s. Approximately 2.6 billion people were affected by natural disasters over the past ten years, compared to 1.6 billion in the previous decade.

    This paper examines some of the key technical, institutional, policy and financial responses required to achieve climate-smart agriculture which sustainably increases productivity, resilience (adaptation), reduces/removes Greenhouse Gases (mitigation), and enhances achievement of national food security and development goals. Building on case studies from the field, the paper outlines a range of practices, approaches and tools aimed at increasing the resilience and productivity of agricultural production systems, while also reducing and removing emissions.
