    Drought is one of the major climatic hazards impacting on the various sectors including crop and livestock in the West African Sahel. Pastoral and agro-pastoral communities in the region are regularly affected by drought, with vulnerability differing with gender, age, wealth status (access to cropland and livestock endowment), geographic location, social networks, and previous exposure to drought. Effective interventions require regular monitoring of vulnerability to drought, for which various quantitative and qualitative approaches exist.

    Background

    Chloroquine combined with primaquine has been the ecommended antimalarial treatment of Plasmodium vivax malaria infections for six decades but the efficacy of this treatment regimen is threatened by chloroquine resistance (CQR). Single nucleotide polymorphisms (SNPs) in the multidrug resistance gene, Pvmdr1 are putative determinants of CQR but the extent of their emergence at population level remains to be explored.

    This paper conducts an integrated assessment of climate change impacts and climate mitigation on agricultural commodity markets and food availability in low- and middle-income countries. The analysis uses the partial equilibrium model GLOBIOM to generate scenarios to 2080. The findings show that climate change effects on the agricultural sector will increase progressively over the century. By 2030, the impact of climate change on food consumption is moderate but already twice as large in a world with high inequalities than in a more equal world.

    This report summarizes the experiences of 19 companies from across the region. Each of the case studies highlights the key corporate governance changes made and the positive impacts that resulted, as reported by the company. The companies represent various countries, sectors, types, and sizes. All of the companies featured are former IFC Advisory Services clients. Some are IFC Investment clients as well. IFC conducted an in-depth corporate governance assessment for each of these companies using IFC’s Corporate Governance Methodology.

    The North Eastern Region (NER) in India is endowed with rich energy resources but faces significant bottlenecks in electricity access and availability levels. The per capita power consumption in NER is one-third of the national average. The region has a shortfall of about 500MW installed capacity against peak demand of about 1950 MW. No significant generation capacity has been added in the recent past. Therefore, inadequate power supply continues a critical constraint to sustainable growth and economic development in the NER.

    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.

    Environmental land degradation is a major impediment to the utilization of land in many arid and semi-arid regions of the World and is a major issue in the East Nile Delta (END), Egypt. Waterlogging and salt-affected soil problems have serious implications for irrigated areas leading to socio-economic and agricultural development problems.

    Urban sprawl is threatening the limited highly fertile land in the Nile delta of Egypt. Landsat TM satellite images of 1984, 1992 and ETM+ of 2006 have been used to study the impact of urban sprawl on agricultural land of the Northern Nile delta, Egypt. Visual interpretation using on screen digitizing and change detection techniques were applied for monitoring the urban sprawl. Combining the land capability map and the urban thematic layer using GIS made it possible to point out the risk of urban expansion on the expense of the highly capable soil class.

    Waterlogged and salt-affected soils are serious environmental hazard indicators for wasteland problems in arid and semi-arid regions of the World. Similarly human activities in agricultural and urban sustainable developments have also led to the development of waterlogging and subsequent salinization of soils leading to many geo-environmental problems. Thus, it is important to be able to monitor, assess and map waterlogged and salt-affected areas at an early stage to develop an effective soil reclamation programme that helps to reduce and prevent a future increase in areas of wasteland.
