    Land Restoration in Latin America and the Caribbean: An Overview of Recent, Ongoing and Planned Restoration Initiatives and Their Potential for Climate Change Mitigation

    Land degradation is a globally recognized problem and restoration of degraded land is currently high on the international agenda. Forest landscape restoration and other restorative ecosystem management activities are important measures that contribute towards reaching the objectives of the Bonn Challenge, which aims to restore 350 million hectares by 2030. In this context, many restoration projects are being planned and implemented in Latin America and the Caribbean (LAC). We present an overview of the location, goals and activities, and an estimated climate change mitigation potential of 154 recent, ongoing and planned restoration projects in LAC. Our analysis suggests that most projects are located in the humid tropics and less attention is paid to drylands. Increasing vegetation cover, biodiversity recovery and recovery of ecological processes are the most common goals. Restorative activities to fulfil these goals were diverse and were related to the type and source of funding that projects receive. For example, projects implemented through the Forest Investment Program (FIP) and the Global Environment Facility (GEF) generally rely on natural or assisted regeneration over large areas (>20,000 ha), whereas Clean Development Mechanism (CDM) projects establish forest plantations, often including exotic monocultures, in smaller project areas (<5000 ha). Projects that are specifically implemented within the scope of Initiative 20 × 20 and other local initiatives that target the local environmental problems, are more varied and rely on a wider portfolio of restorative activities, such as erosion control, exclusion of grazing and mixed plantations. These projects are usually implemented in smaller project areas (<5000 ha). All projects had the potential to contribute to climate change mitigation by storing additional forest aboveground biomass through natural regeneration, assisted regeneration or establishing a plantation. Further analysis of the implemented activities is an important next step to investigate their effectiveness in terms of goals achieved under Initiative 20 × 20 and the Bonn Challenge. This would provide information for future restoration projects and upscaling of restorative activities in a wider area. View Full-Text

    This database is produced as part of the Comparative Research Project on Landscape Restoration for Emissions Reductions, a collaboration between Wageningen University and Research (Laboratory of Geo-Information Science and Remote Sensing) and The International Center for Tropical Agriculture (CIAT), supported by USAID. The aim of this research project is to map and characterize planned, ongoing and finished restoration projects in LAC countries. The database contains detailed project information from 154 restoration projects in LAC. Projects from various initiatives (20x20, GEF, UNFCCC CDM, FIP, and many others) are included in the database. We used project reports and information from websites from the various initiatives to assemble project information for this database. Projects from the following databases were included: •Cerrón, J., del Castillo, J., Mathez-Stiefel, S.-L. and Thomas, E. (2017) Lecciones aprendidas de experiencias de restauración en el Perú. Bioversity, ICRAF, SERFOR. •Méndez-Toribio, M., Martínez-Garza, C., Ceccon, E. and Guariguata, M. R. (2018) La restauración de ecosistemas terrestres en México. Estado actual, necesidades y oportunidades. Documentos Ocasionales 185. CIFOR. doi: 10.17528/cifor/006853. •Murcia, C. and Guariguata, M. (2014) La restauración ecológica en Colombia.

    Comparative assessment of first generation restoration activities in Latin America to support sub-national restoration efforts for generating emissions reductions

    Land degradation is a serious global problem, with economic consequences as demands for food, feed, fuel, and ecosystem services increase. Restoration of degraded lands is an important component of climate change mitigation and adaptation schemes, poverty reduction efforts, and ensuring food security. The 20x20 initiative aims to bring 20 million hectares of land in Latin America and the Caribbean into restoration by 2020. The purpose of this research is to identify institutional and technical arrangements that lead to successful implementation of restoration activities and to improve understanding of what works and what does not in restoration. We start by mapping and producing a database of restoration activities from the 20x20 initiative and characterize these by populating the database with detailed information on the approaches taken by the different activities. Subsequently we overlay the location of the activities on maps of land degradation, deforestation, biomass, emission factors, and emissions hotspots to analyse the potential for environmental impact of the activities. The analysis will enable us to understand how projects are addressing the underlying drivers of land degradation and if they are likely to have longer-term impacts. We will give recommendations on how restoration can contribute to UNFCCC objectives and SDG goals.

    For the semi-detailed characterization of inland valleys systems in the Ivory Coast, transect sampling was used to describe valley morphology, soils, and land use characteristics. Initially, for each valley one transect with a width of 200 to 400 m was proposed. More recently, use of a larger number of transects has been suggested. However, there is no statistical basis for either the number of transects to be described or their optimal width. Two sets of aerial photographs (1979, scale 1:50 000, and 1996, scale 1:20 000) of the Boundiali key area were processed and the results digitized. Using GIS, sets of transects with different width were made, and used for the determination of the sample size for estimating the land use ratio and the valley bottom ratio at valley system level with given confidence intervals. These results were validated with data from the field and with sets of pre-selected transects. The calculated sample size is based on simple random sampling and depends on both transect width and variability in the study area. For the characterization of inland valleys with reasonable confidence intervals, the sample size for random sampling is too large for the semi-detailed characterization method. Smaller samples of transects selected on the basis of sub-recent aerial photographs gave comparable results for land cover characteristics estimation as the larger samples for random sampling. There is scope for reducing sample size by formalizing criteria for transect placement on the basis of the earlier aerial photographs.
