Atriplex nummularia has been extensively planted in Northern Africa to combat desertification. However, few studies evaluated the effectiveness of these interventions. This study aimed at assessing the dynamic performance of a number of Atriplex plantations located in the Marrakech province in terms of multitemporal dry biomass production. Three SPOT 5 images (2004, 2008 and 2012) and field biomass measurements were integrated to quantify the dry biomass production dynamics of plantations established from 1996 to 2007. Different plant ages covered the whole plant life cycle curve.

The West Asia–North Africa (WANA) region has a land area of 1.7 billion ha, and a population of 600 million. Desertification and soil degradation are severe problems in the region. The problem of drought stress is exacerbated by low and erratic rainfall and soils of limited available water holding capacity and soil organic carbon (SOC) content of less than 0.5 per cent. The SOC pool of most soils has been depleted by soil degradation and widespread use of subsistence and exploitative farming systems.
Mediterranean areas of both southern Europe and North Africa are subject to dramatic changes that will affect the sustainability, quantity, quality, and management of water resources. Most climate models forecast an increase in temperature and a decrease in precipitation at the end of the 21st century. This will enhance stress on natural forests and shrubs, and will result in more water consumption, evapotranspiration, and probably interception, which will affect the surface water balance and the partitioning of precipitation between evapotranspiration, runoff, and groundwater flow.
The Mediterranean region covers about 854 million ha, but only 118 million (or 14 per cent) are suitable for agricultural production. In North Africa and the Middle East (MENA), agricultural land covers about 5 per cent; in Egypt and Algeria, it occupies less than 4 per cent and, in Libya, less than 2 per cent of the total national land area. Across the Mediterranean region land use divides between natural pastures/rangelands (ca. 15 per cent), forests and woodlands (ca. 8 per cent), with the ca.
The dry rangelands of West Asia and North Africa are fragile and severely degraded due to low rainfall and mismanagement of natural resources. Rainwater harvesting (RWH) interventions are used to increase soil moisture content, vegetation cover, and productivity. However, adoption of rainwater harvesting by communities is slow. To understand adoption constraints and to develop options for sustainable integration of rainwater harvesting, a benchmark watershed was established in the dry rangelands of Jordan.
For many centuries, the people of the Near East and North Africa (NENA) Region were able to cope, and even flourish, under conditions of water scarcity. However, with decades of relentless high rate of population growth, rapid urbanization, and uncharacteristically excessive consumption patterns, the region is now facing unprecedented levels of pressure on its natural resources.
Our region is food insecure and a net importer of foods. It produces much less food than it requires due to many factors, such as limited arable land and shortage of water resources, and below world average agricultural productivity in many cases. In addition, the region suffers from excessive food losses and wastes. FAO estimated recently that food losses and waste in the world amounts to about 1.3 billion metric tons, and we estimate that our region’s share of these losses and wastes is very significant.
This paper begins by exploring what the term family farming means and how appropriate it is in the NENA region. It will explore more generally the role of farming and agriculture in the broader political economy of the region. The paper establishes the distinctive features of the region, what might be generalised and what might not be so common between countries with contrasting patterns of development.
This document provides a clear and comprehensive account for the application of marine spatial planning (MSP) within the Regional Commission for Fisheries (RECOFI) region. It builds on regional technical workshops, held under the auspices of the Food and Agriculture Organization of the United Nations (FAO), aimed principally at improving the prospects for fisheries and aquaculture in the Near East. Marine spatial planning provides a step-by-step process that allows for the cooperative integration of the major marine uses and users within a defined marine area.
