    As the United Nations Decade on Biodiversity 2011–2020 comes to a close and countries prepare to adopt a post-2020 global biodiversity framework, this edition of The State of the World’s Forests (SOFO) examines the contributions of forests, and of the people who use and manage them, to the conservation and sustainable use of biodiversity.

    Kenya

    The area northwest of Mt Kenya is undergoing rapid land use changes caused by a population influx. Rapid population growth and subsequent pressure on land raise the problem of how to increase and sustain agricultural production while at the same time conserving the natural resources (montane forest with Olea africana and Juniperus procera as main species at 2900 m asl.). Deterioration in soil physical and chemical properties following deforestation for agriculture can adversely affect crop production, especially from soils on mountain slopes.

    Kenya

    This paper describes the environmental degradation that has occurred in Kenya since early this century, initially due to the introduction of plantation farming. Forests have been further targeted for farmland, fuel wood, building materials and hardwood species. Range land species have also become threatened due to continued infiltration of the population. The discussion considers the efforts of the Kenyan government to legislate and administrate against the further loss of natural resources and the consequent development of environmental awareness among the populace.

    MAPTenure: Enabling Tenurial Clarity for Orange Areas of Central India cover image

    India

    More than half the villages of Madhya Pradesh and Chhattisgarh are affected by a peculiar issue of tenurial ambiguity called “orange areas.” This issue impacts nearly 1.2 million hectares and 1.5 million, largely poor, landless and tribal families, that depend on these lands for food, fuel, fodder and other sources of income. This lack of tenurial clarity also impacts forest protection outcomes in the state and constrains the achievement of biodiversity, water and climate targets.

    Peatland plays an important ecological and economic role in many countries all over the world. At the same time, due to various human and non-human interventions, peatland is also a fragile ecosystem, which is currently facing severe problems, such as deforestation, fires, and peat subsidence. Peat subsidence is currently one of the most severe but least recognized issues. Because of its interconnectedness with other peatland problems, peat subsidence intensifies when there is a lack of proper interventions.

    Deforestation is recognized as a major driver of the loss of biodiversity and ecosystem services. It also disturbs natural processes such as biogeochemical, hydrological, and ecological cycles. In Malawi, deforestation is estimated to be responsible for the loss of 33,000 hectares per year, and is mainly attributed to agriculture expansion, tobacco growing, and excessive use of biomass. However, little research has been conducted at either the local level or that of forests located on customary land.

    In this study, methods, originally developed to assess life course trajectories, are explored in order to evaluate land change through the analysis of sequences of land use/cover. Annual land cover maps which describe land use/land cover change for the 1985–2017 period for a large region in Northeast Brazil were analyzed. The most frequent sequences, the entropy and the turbulence of the land trajectories, and the average time of permanence were computed. Clusters of similar sequences were determined using different dissimilarity measures.

    Deforestation and forest degradation (D&D) in the tropics have continued unabated and are posing serious threats to forests and the livelihoods of those who depend on forests and forest resources. Smallholder farmers are often implicated in scientific literature and policy documents as important agents of D&D. However, there is scanty information on why smallholders exploit forests and what the key drivers are. We employed behavioral sciences approaches that capture contextual factors, attitudinal factors, and routine practices that shape decisions by smallholder farmers.

    The Verified Carbon Standard (VCS) recommends the Figure of Merit (FOM) as a possible metric to confirm models that simulate deforestation baselines for Reducing Emissions from Deforestation and forest Degradation (REDD). The FOM ranges from 0% to 100%, where larger FOMs indicate more-accurate simulations. VCS requires that simulation models achieve a FOM greater than or equal to the percentage deforestation during the calibration period.
