Thus we would increase carbon uptake by grubbing up "wooded areas containing slow-growing trees" (that is, natural forest) and planting "faster growing species".
"It is about reducing carbon loss by reducing deforestation, and increasing carbon uptake by allowing young forests to regrow," Dr. Lourens Poorter, professor of functional ecology at Wageningen University in the Netherlands and lead author of the study, told The Huffington Post.
In contrast, we find that high diffuse light fraction does not increase the carbon uptake rate in croplands and grasslands; for these ecosystems, we estimate that high AOD conditions reduce GPP by ∼17% during midday hours.
Another option is to increase the carbon uptake by letting forest stands grow for longer periods [6].
Two other alternatives could be a large scale deployment of artificial photosynthesis [7], or to increase the carbon uptake of the oceans by adding active absorbers.
However, in predicting an enhanced terrestrial carbon sink in the future (Pinsonneault et al. 2011; Bala et al. 2013), the expectation is reversed rather than relying on stable ecosystem functioning, society stands to benefit from a dynamic ecosystem function, specifically, increasing net carbon uptake through time.
Therefore, for a long-term sustainable health agriculture and a healthy life for all other organisms on earth, We need find a way to stimulate the growth of beneficial microorganisms including those that fix N2, create symbiotic association with plant roots (mycorrhizal fungi, rhizobia, actinomycetes, diazotrophic bacteria) to increase nutrient-uptake ability and increase carbon storage in soil.
Ideas include iron fertilization of the oceans to enhance uptake of carbon by the resulting blooms of phytoplankton, planting vast forests of fast-growing trees to sequester carbon18 or altering agricultural practices to increase carbon storage in soils19.
Our results suggest twice higher increase in carbon uptake in temperate forests than a study based on 15N tracer field experiments [10], which suggested increase of 0.25 Pg carbon per year for temperate forests.
