“…Diversidad arbórea de las aéreas forestales El papel de la vegetación remanente en paisajes fragmentados es apreciado, no solo por su capacidad de acumulación de carbono y mitigación del cambio climático, sino por su contribución a la regeneración natural y conservación de la biodiversidad (Chazdon, 2008;Martínez-Sánchez et al, 2015;Mora et al, 2018).…”

El rápido aumento de la producción ganadera ha provocado impactos ambientales, como la deforestación, la pérdida de biodiversidad, la degradación del suelo y las emisiones de gases de efecto invernadero (GEI). En el estado de Chiapas, dichas emisiones han aumentado especialmente por la conversión de tierras forestales a pastizales y la fermentación entérica del ganado. La remoción de CO2 atmosférico por actividades forestales y agroforestales dentro de las unidades de producción ganadera puede reducirlas significativamente. El principal objetivo de esta investigación fue conocer el potencial de almacenamiento de carbono en áreas forestales, para conocer su contribución en la mitigación de GEI dentro de una unidad de producción ganadera en Villaflores, Chiapas. Se establecieron 12 parcelas de muestreo en áreas forestales y potreros para evaluar el carbono en biomasa viva aérea, biomasa de raíces, hojarasca, madera muerta y carbono orgánico del suelo. El promedio de almacenamiento de carbono en áreas forestales fue 144.45 Mg C ha-1 comparado con 75.95 Mg C ha-1 en los potreros. El almacén de carbono en biomasa viva, como se esperaba fue más alto en áreas forestales que en potreros, pero no hubo diferencia significativa en el reservorio de carbono orgánico del suelo. El rancho en estudio posee 24.7 ha (40 % de la superficie) de áreas forestales con alta diversidad de especies arbóreas, y si se decidiera deforestar para establecer pasturas contribuiría con 6 353.95 Mg de emisiones de CO2. Los resultados permitirán estimar la remoción anual de carbono con futuras remediciones.

“…Studies of land cover change are often biased towards forest loss (Achard et al 2007;Hansen et al 2010;Stibig et al 2014), despite evidence that regenerating forests possess faster biomass recovery, higher productivity and carbon uptake compared to old-growth forests (Zahawi et al 2015;Poorter et al 2016;Mora et al 2018).

Deforestation and forest degradation are major drivers of global environmental change and tropical forests are subjected to unprecedented pressures from both. For most tropical zones, deforestation rates are averaged across entire countries, often without highlighting regional differentiation. There are also very few estimates of forest degradation, either averaged or localized for the tropics. We quantified regional and country‐wide changes in deforestation and forest degradation rates for Madagascar from Landsat temporal data (in two intervals, 1994–2002 and 2002–2014). To our knowledge, this is the first country‐wide estimate of forest degradation for Madagascar. We also performed an intensity analysis to categorize the magnitude and speed of transitions between forest, vegetation matrix, cultivated land and exposed surface. We found significant regional heterogeneity in deforestation and forest degradation. Deforestation rates decreased annually in lowland evergreen moist forest by −0.24% and in all other vegetation zones. Forest degradation rates had annual increases in the same period in lowland evergreen moist forest (0.09%), littoral forest (0.06%) but decreased in medium altitude moist evergreen forest (−0.25%), dry deciduous forest (−0.23%) and scelrophyllous woodland (−0.61%) in the same period. Despite these regional differences, higher rates of deforestation and forest degradation were consistently driven by rapid and large‐sized conversions of largely intact forest to cultivated lands and exposed surfaces, most of which occurred between 1994 and 2002. These results suggest that while targeted conservation projects may have reduced forest degradation rates in some areas (e.g. medium altitude moist evergreen forest), the drivers of land cover change remain intense in relatively neglected regions. We advocate a more balanced approach to future conservation initiatives, one recognizing that deforestation and forest degradation, particularly in tropical Africa, are often driven by region‐specific conditions and therefore require conservation policies tailored for local conditions.

“…Clearly, a number of conditions are needed to set up such projects, including the creation of incentive schemes which focus on carbon gained through natural forest regeneration, and capacity building (CONAFOR 2017). A technical difficulty is that annual gains in AGB per hectare tend to be low; for SDTF, they are between one to five Mg/ha/year (IPCC 2006, Mora et al 2017, Rozendaal et al 2017, which means that estimates of AGB increases will have to be extremely accurate. What my modeling procedure could contribute in this context is spatial focus, in terms of where within the community territory REDD+ enhancement efforts could best be targeted.…”

“…Enhancement of forest carbon stocks implies reversal of degradation and recuperation of carbon stocks, usually by removing or better managing the activities that cause them to degrade. The gains are generally small, ranging from one to five Mg/ha/year, on an annual basis (IPCC 2006, Mora et al 2017, Rozendaal et al 2017 with small slope angles should show higher biodiversity, basal area, and annual net primary productivity than steeply sloping sites , Cielo-Filho et al 2007, Laurance et al 2010. In SDTF biomass is usually understood to be determined by water availability , which is strongly affected by slope .…”

Tropical forests are of global concern in the context of climate change. This is because forests can both emit carbon dioxide (CO2), an important greenhouse gas (GHG), and sequester it in the biomass of trees. The ability of a given type of forest to hold stocks of carbon is strongly influenced both by topography of the landscape and by the human uses that are present. Topography is not just indicated in the literature as a template within the landscape that defines the patterns of density biomass, but also as a driving factor of human uses. While altitude, slope and terrain convexity, among others, show a relationship with biomass patterns, human activities such as shifting cultivation, grazing and extraction of
