    Increasing rates of deforestation in tropical rain forests have been linked to agricultural encroachment. How well trees recover into a more species rich ecosystem after restoration planting remains unclear. The aim of the study was to evaluate the recovery of communities of tree, assess the influence of understory vegetation like Acanthus pubescens, and Pennisetum urpureum, on the recovery in Kibale National Park (KNP), Uganda. We studied six restored forests fragments ranging in age from 3 to 16 years and three primary forests. Our results showed that although recovery with natural regeneration was more effective than restoration planting the latter enhanced recruitment of native tree seedling. Tree recovery was generally correlated with age so that species density and diversity increased although at different rates. A reverse pattern was found for dominance but no clear pattern was found for tree density. Understory vegetation like Acanthus pubescens and Pennisetum purpureum negatively correlated with species density, tree density and diversity but a positive correlation was found for dominance. Although restoration planting can enhance recovery, understory vegetation significantly affects recovery of degraded forests. This can affect the cost of restoration of degraded areas.

    The FAOSTAT emissions database is composed of several data domains covering the categories of the IPCC Agriculture, Forestry and Other Land Use (AFOLU) sector of the national GHG inventory. Energy use in agriculture is additionally included as relevant to emissions from agriculture as an economic production sector under the ISIC A statistical classification, though recognizing that, in terms of IPCC, they are instead part of the Energy sector of the national GHG inventory. FAO emissions estimates are available over the period 1961–2018 for agriculture production processes from crop and livestock activities. Land use emissions and removals are generally available only for the period 1990–2019. This analytical brief focuses on overall trends over the period 2000–2018.

    FAO Strategy on Climate Change 2022–2031 2022
    The FAO Strategy on Climate Change 2022–2031 was endorsed by FAO Council in June 2022. This new strategy replaces the previous strategy from 2017 to better FAO's climate action with the Strategic Framework 2022-2031, and other FAO strategies that have been developed since then. The Strategy was elaborated following an inclusive process of consultation with FAO Members, FAO staff from headquarters and decentralized offices, as well as external partners. It articulates FAO's vision for agrifood systems by 2050, around three main pillars of action: at global and regional level, at country level, and at local level. The Strategy also encourages key guiding principles for action, such as science and innovation, inclusiveness, partnerships, and access to finance.
