One of today's environmental challenges is reducing greenhouse gases (GHG) through reforestation. Forest plantations with adequate species composition and management sequester carbon and restore degraded areas simultaneously, but methods to estimate their biomass must be refined. In Mexico's Lacandon Jungle, 103 trees were harvested to determine allometric equations for four abundant Neotropical species with high potential for restoration: Guazuma ulmifolia, Trichospermum mexicanuum, Inga vera and Ochroma pyramidale. The best biomass predictors were diameter at breast height and at the base, which generated allometric relations with r² 0.90 or higher. Based on these relations, average biomass accumulation in two-year-old monocultures of Inga, Ochroma, Trichospermum and Guazuma were calculated at 6.60, 30.80, 47.62 and 48.12 Mg ha-1. Restoration plantations with the last two species are a potentially efficient strategy to reduce atmospheric carbon. The high inter-site and inter-species variability, partly related to differences in survival and growth, indicate the need for multi-site experimental designs in order to generalize the results of biomass estimation.

    SUMMARY An effective way of reducing greenhouse gas content in the atmosphere is carbon dioxide (CO2) geo-sequestration in saline aquifers. The main objective of this study is to develop a 3-D numerical model to identify the optimum CO2 storage capacity in saline aquifers by studying the factors...

    Limiting climate change to 2 °C with a high probability requires reducing cumulative emissions to about 1600 GtCO over the 2000-2100 period. This requires unprecedented rates of decarbonization even in the short-run. The availability of the option of net negative emissions, such as bio-energy...

    Shrub willow biomass crops (SWBC) have been developed as a biomass feedstock for bioenergy, biofuels, and bioproducts in the northeastern and midwestern USA as well as in Europe. A previous life cycle analysis in North America showed that the SWBC production system is a low-carbon fuel source....
