    Cameroon

    The present study aims to explore economic and socio-demographic factors that influence a household’s probability to switch from firewood to cleaner fuels (kerosene and LPG) in northern Cameroon. The paper employs an ordered probit model to construct cooking patterns and fuel choices. Three main cooking sources are considered: firewood, kerosene, and liquefied petroleum gas. Utilized data are derived from a national survey conducted in 2004 by the Cameroonian National Institute of Statistics.

    This chapter explores the interface between land tenure rights and soil security and screens through the Cameroonian land tenure legislation in order to identify relevant provisions that guarantee soil security.

    Drylands occupy more than 40% of the world’s land area and are home to some two billion people. This includes a disproportionate number of the world’s poorest people, who live in degraded and severely degraded landscapes. The United Nations Convention to Combat Desertification states on its website that 12 million hectares are lost annually to desertification and drought, and that more than 1.5 billion people are directly dependent on land that is being degraded, leading to US$42 billion in lost earnings each year.

    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.

    Land degradation and desertification are among the biggest environmental challenges of our time. In the last 40 years, we lost nearly a third of the world’s arable farmland due to erosion, just as the number of people to be fed from it almost doubled. That’s why the UN General Assembly declared 2015 as the International Year of Soils. And the good news is that this new report shows that while Africa remains the most severely a«ected region, the benefit of taking action across the continent outweighs the cost of implementing it: not just by a little, but by a factor of seven.

    The massive increase in demand for woodfuel for cooking caused by sudden influxes of refugees and other displaced people is usually the main driver of forest degradation and deforestation in displacement settings. It places enormous pressure on nearby forests and woodlands and is often a source of tension between the host and displaced communities. A lack of sufficient cooking fuel also has an impact on the nutrition and health of vulnerable people in such settings.

    El presente estudio sobre las causas directas y subyacentes de deforestación y degradación de los bosques en Guinea Ecuatorial se ha realizado en el marco del proceso de desarrollo de la Estrategia Nacional REDD+ (EN-REDD+) y del Plan Nacional de Inversión REDD (PNI-REDD+). La EN-REDD+ y el PNI-REDD+ aspiran a guiar y apoyar los esfuerzos de todas las partes implicadas en la implementación de REDD+ , que tiene como objetivo reducir las emisiones, aumentar el secuestro de carbono en los bosques y mejorar la gestión y conservación de las reservas forestales de carbono.

    Time series of vegetation indices (VI) derived from satellite imagery provide a consistent monitoring system for terrestrial plant productivity. They enable detection and quantification of gradual changes within the time frame covered, which are of crucial importance in global change studies, for example. However, VI time series typically contain a strong seasonal signal which complicates change detection. Commonly, trends are quantified using linear regression methods, while the effect of serial autocorrelation is remediated by temporal aggregation over bins having a fixed width.
