“…The reported minimum and average above-ground carbon stock data that were used in the carbon-stock accounting procedure were comparable to other studies in South-East Asia [3,4]. However, the maximum time-averaged above-ground carbon stock data computed with the coupled modelling procedure in 2029 were in parts higher than other estimates for tropical environments [51,52] as a result of overall wide range of values reported in literature. This type of uncertainty could be captured fairly well by the sensitivity analysis, further revealing the wide variation in prospected above-ground carbon stocks for 2029.…”

Abstract:The objective of this study was to examine whether the coupling of a land-use change (LUC) model with a carbon-stock accounting approach and participatory procedures can be beneficial in a data-limited environment to derive implications for environmental management. Stakeholder-based LUC scenarios referring to different storylines of agricultural intensification and reforestation were simulated to explore their impact on above-ground carbon (AGC) for a period of twenty years . The watershed of Mae Sa Mai, Northern Thailand was used as a case study for this purpose. Coupled model simulations revealed that AGC stocks could be increased by up to 1.7 Gg C through expansion of forests or orchard areas. A loss of up to 0.4 Gg C would occur if vegetable production continue to expand at the expense of orchard and fallow areas. The coupled model approach was useful due to its moderate data demands, enabling the comparison of land-use types differing in AGC build-up rates and rotation times. The scenario analysis depicted clear differences in the occurrence of LUC hotspots, highlighting the importance of assessing the impact of potential future LUC pathways at the landscape level. The use of LUC scenarios based on local stakeholder scenarios offer a higher credibility for climate mitigation strategies but also underline the need to co-design policy frameworks that acknowledge the heterogeneity of stakeholder needs and environmental management frameworks.

“…Hence, it is unfortunately not possible to conclude whether the equations are statistically valid or not. Despite of this limitation, the two equations presented by those authors were developed grouping four average ( The analysis of existing studies that tested the dependence of aboveground biomass (and/ or size parameters such as canopy height or diameter at breast height) with latitude or climatic parameters in terrestrial forest ecosystems shows that the percentage of variability explained by the independent variable is also low and rarely exceeds 30% (Malhi et al 2006, Moles et al 2009, Stegen et al 2011, Becknell et al 2012). In the case of carbon sequestration, no regression was significant, which most likely does not indicate the absence of a dependence of carbon sequestration on the climatic parameters and latitude, but rather the limitations of the quantity and quality of data available in the literature, as discussed in section 3.1.…”

In order to contribute to understand the factors that control the provisioning of the ecosystem service of carbon storage by mangroves, data on carbon stock and sequestration in the aboveground biomass (AGB) from 73 articles were averaged and tested for the dependence on latitude, climatic parameters, physiographic types and age. Global means of carbon stock (78.0 ± 64.5 tC.ha -1 ) and sequestration (2.9 ± 2.2 tC.ha -1 .yr -1 ) showed that mangroves are among the forest ecosystems with greater capacity of carbon storage in AGB per area. On the global scale, carbon stock increases toward the equator (R²=0.22) and is dependent on 13 climatic parameters, which can be integrated in the following predictive equation: Carbon Stock in AGB = -16.342 + (8.341 x Isothermality) + (0.021 x Annual Precipitation) [R²=0.34; p < 0.05]. It was shown that almost 70% of carbon stock variability is explained by age. Carbon stock and sequestration also vary according to physiographic types, indicating the importance of hydroperiod and edaphic parameters to the local variability of carbon stock. By demonstrating the contribution of local and regional-global factors to carbon stock, this study provides information to the forecast of the effects of future climate changes and local anthropogenic forcings on this ecosystem service.

“…Se encontró que la cantidad de biomasa acumulada en los árboles tiende a ser mayor en los sitios más viejos. Becknell et al (2012) reportan el mismo comportamiento en bosque seco y seco transición húmedo en la provincia de Guanacaste. Por su parte, Ulate (2011) obtuvo valores promedio de biomasa para la zona de vida bosque seco tropical (bs-T) de 79,58, 129,59 y 161,33 Mg ha -1 en bosques secundarios tardíos (> 20 años), intervenidos y primarios, respectivamente; observándose la misma relación entre la edad del bosque y la cantidad de biomasa.…”

Los resultados obtenidos de biomasa en el bosque primario están por encima del promedio encontrado por Ulate (2011), sin embargo el valor se encuentra dentro del ámbito de distribución normal descrito por Becknell et al (2012). Para estudios posteriores se recomienda considerar la biomasa que aportan los árboles caídos ya que constituyen una parte importante de los combustibles, sin embargo, la determinación de estos valores va a depender del estado de descomposición de la madera.…”

Se cuantificó el combustible forestal superficial de los árboles en pie y del mantillo orgánico. También, se caracterizó la composición florística, en tres tratamientos de estadios sucesionales, de 10-25 años (29,88 ha) mayor a 30 años (22,75 ha) y bosque primario (38,36 ha). Se estableció un diseño de muestreo de parcelas temporales simple aleatorio estratificado con siete repeticiones por tratamiento (15 x 50 m), con sub muestreo de parcelas de 0,9 m2 para la cuantificación del material superficial del suelo. Las muestras de mantillo fueron llevadas al laboratorio del Centro de Investigación en Integración Bosque Industria (CIIBI) del Instituto Tecnológico de Costa Rica en Cartago. Se realizaron pruebas de consumo del combustible. Se determinó el índice de peligrosidad de combustibles superficiales (IPCS). En los tres sitios se identificó un total de 567 individuos, distribuidos en 57 especies pertenecientes a 28 familias. Cinco familias fueron representadas por solamente un individuo. Diez especies estuvieron presentes en los tres estadios sucesionales. La mayor cantidad de especies se encontraron en el bosque primario (37), mientras que el bosque mayor a 30 años presentó el mayor número de familias (20). El bosque primario presentó la mayor cantidad de combustible disponible en los árboles con un valor de 254,67 Mg ha-1. Para el bosque secundario maduro (> 30 años) se estimó una biomasa promedio de 196,27 Mg ha-1. Los valores más bajos (71,31 Mg ha-1) correspondieron al bosque de 10-25 años. Los combustibles acumulados en el mantillo fueron mayores para el bosque primario (14,06 Mg ha-1), seguido por el bosque mayor a 30 años (11,87 Mg ha-1), y por último el bosque de 10-25 años (7,75 Mg ha-1). Se encontró que la cantidad de combustibles tiende a ser mayor en los sitios más viejos. Se obtuvo un valor promedio del IPCS de 754,32, según el criterio de clasificación descrito por Galiana (2009) y modificado por Parra (2013), los tres estadios de sucesión se ubicaron en la categoría de peligrosidad media-baja.
