    Local-Scale Mapping of Biomass in Tropical Lowland Pine Savannas Using ALOS PALSAR by Dimitrios Michelakis, Neil Stuart, German Lopez, Vinicio Linares, Iain H. Woodhouse

    Published 2014-09-01
    “…The predicted average biomass, from the mapping for savannas woodlands occurring within two of Belize’s larger protected areas, agree closely with previous biomass estimates for these areas based on ground surveys and forest inventories (error ≤20%). However, biomass estimates derived for these protected areas from two biomass maps produced at coarser resolutions (500 m and 1000 m) from global datasets overestimated biomass (errors ≥275% in each dataset). …”

    Applying a systems approach to assess carbon emission reductions from climate change mitigation in Mexico’s forest sector by Marcela Olguin, Craig Wayson, Max Fellows, Richard Birdsey, Carolyn E Smyth, Michael Magnan, Alexa J Dugan, Vanessa S Mascorro, Armando Alanís, Enrique Serrano, Werner A Kurz

    Published 2018-01-01
    “…Using information from the National Forest Monitoring System (e.g. forest inventories, remote sensing, disturbance data), we demonstrate that activities aimed at reaching a net-zero deforestation rate can yield significant CO _2 e mitigation benefits by 2030 and 2050 relative to a baseline scenario (‘business as usual’), but if combined with increasing forest harvest to produce long-lived products and substitute more energy-intensive materials, emissions reductions could also provide other co-benefits (e.g. jobs, illegal logging reduction). …”
