Has the burden of depression been overestimated?
OBJECTIVE To investigate whether high estimates of the burden of depression could be attributed to an overestimation of disability weights (reflecting more severe disability). METHODS We derived disability weights that were tailored to prevalence data. Empirical disability data from a Dutch community survey was used to describe three classes of severity of depression and their proportional pr...
متن کاملSoil Organic Carbon Sequestration with Conservation Agriculture in the Southeastern Usa: Potential and Limitations
The carbon (C) cycle is the basis for greenhouse gas emissions and global warming. Globally, agriculture is responsible for about 20% of the greenhouse gas emissions. However, this percentage does not take into account the large role that agriculture plays in the opposing processes of photosynthesis and respiration (Figure 1), as well as contributions to soil organic C sequestration via animal ...
متن کاملGross primary production of global forest ecosystems has been overestimated
Coverage rate, a critical variable for gridded forest area, has been neglected by previous studies in estimating the annual gross primary production (GPP) of global forest ecosystems. In this study, we investigated to what extent the coverage rate could impact forest GPP estimates from 1982 to 2011. Here we show that the traditional calculation without considering the coverage rate globally ove...
متن کاملCarbon sequestration opportunities in organic agriculture
At the present time, soil carbon sequestration is of paramount importance to address the imminent threat of increased atmospheric carbon dioxide, which is looming large on the very survival and existence of the biome. The quantum of all carbon everywhere in the globe is same and fixed. It exists to the tune of 800 Pg in the atmosphere, 1700 Pg in terrestrial and 38000 Pg in aquatic ecosystem. E...
متن کاملCarbon Sequestration, Co-Benefits, and Conservation Programs
Land use changes to sequester carbon also provide “co-benefits,” some of which (for example, water quality) have attracted at least as much attention as carbon storage. The non-separability of these co-benefits presents a challenge for policy design. If carbon markets are employed, then social efficiency will depend on how we take into account co-benefits, that is, externalities, in such market...
