    As an international actor in addressing food insecurity among refugees and other migrants, the World  Food Programme (WFP) has undertaken a research study to determine the role that food security plays in cross-border migration. Given the dearth of data on this topic, the WFP  study sought to answer some of the following questions: What is it that compels people to leave their homes? What role does food insecurity play in migration? Are these factors common across all international migrants, or do unique root causes spur specific migrant populations to move from their homes?

    Despite six years of crisis in Syria, agriculture remains a key part of the economy. The sector still accounts for an estimated 26 percent of gross domestic product (GDP) and represents a critical safety net for the 6.7 million Syrians – including those internally displaced - who still remain in rural areas. However, agriculture and the livelihoods that depend on it have suffered massive loss. The Food and Agriculture Organization of the United Nations (FAO) has now conducted the first comprehensive nationwide assessment on the cost of the war to the agriculture sector.

    The NATO Parliamentary Assemblies’ Science and Technology Committee drafted a new report on Food and Water Security in the Middle East and North Africa. The report underlines that pressures on natural resources and connected impacts on food production are factors that contribute to the (in-) security of the MENA region. The document summarizes causes as well as possible technical and governance approaches to improve food and water security in the region. The initiative shows that the role of environmental resources is increasingly taken seriously in the sphere of security policy.

    After the severe droughts in the 1970s and 1980s, and subsequent debates about desertification, analyses of satellite images reveal that the West African Sahel has become greener again. In this paper we report a study on changes in tree cover and tree species composition in three village landscapes in northern Burkina Faso, based on a combination of methods: tree density change detection using aerial photos and satellite images, a tree species inventory including size class distribution analysis, and interviews with local farmers about woody vegetation changes.

    Dans le contexte sahélien, depuis la fin des années 2010 des discours normatifs sur la jeunesse et le pastoralisme se sont développés, trop souvent basés sur des catégories standards impropres à décrire les réalités locales et associées dans une chaine de causalité trompeuse: désœuvrement des jeunes, migrations, participation aux violences armées, conflits violents catégorisés de manière simpliste comme ethniques et socioprofessionnels, économie criminelle, dégradation des ressources, changement climatique.Il y a un paradoxe entre le développement de ces discours généraux et le manque de do

    The importance of studying coastal areas is justified by their resources, ecosystem services, and key role played in socio-economic development. Coastal landscapes are subject to increasing demands and pressures, requiring in-depth analyses for finding appropriate tools or policies for a sustainable landscape management.

    Historic urban landscapes (HULs) are composed of layers of history and memories that are embedded in physical monuments, buildings, and memorials. Physical built fabric stores both personal and cultural memory through long association with communities. Rapid changes due to demolition and redevelopment change the nature of these places and, in turn, affect these memory storages. This paper investigates whether historical city inhabitants consider cultural memories important when managing their HULs.

    The Re-Greening of the West African Sahel has attracted great interdisciplinary interest since it was originally detected in the mid-2000s. Studies have investigated vegetation patterns at regional scales using a time series of coarse resolution remote sensing analyses. Fewer have attempted to explain the processes behind these patterns at local scales. This research investigates bottom-up processes driving Sahelian greening in the northern Central Plateau of Burkina Faso—a region recognized as a greening hot spot.

    Desertification is defined as land degradation occurring in the global drylands. It is one of the global problems targeted under the Sustainable Development Goals (SDG 15). The aim of this article is to review the history of desertification and to evaluate the scientific evidence for desertification spread and severity. First quantitative estimates of the global extent and severity of desertification were dramatic and resulted in the establishment of the UN Convention to Combat Desertification (UNCCD) in 1994. UNCCD’s task is to mitigate the negative impacts of desertification in drylands.

    Groundwater resources became a recognized enabler of important rural and socio-economic development in Mediterranean countries. However, the development of this groundwater economy is currently associated with an increased pressure on the available resource and negative implications on the socio-ecological system. Managing complex socio-ecological systems, such as those that occur in water resource management, is a multi-actor, multi-scale and dynamic decision-making process.
