“…To see whether this process can be sustained, we also need to compare these yields with models of soil carbon to see whether steady state yields can be sustained. Carbon data come from some studies of larger rivers and from small research watersheds, such as those in the For any watershed with sediment data, (2) and (3) can be used to estimate POC fraction, fr, and carbon yields, Yo Mean Runoff (mm yr -1) [Schlesinger, 1986]. Schlesinger and Melack [1981] acknowledge that erosion rates in agricultural watersheds can be high, enough to produce yields of 100 g C m -2 yr 4, but they state that these yields must decline after initial cultivation.…”

Schlesinger [1986] argues that most carbon lost from agricultural soils is oxidized to carbon dioxide. Likewise, carboncycle models, such as Houghton et al [1987], return this lost soil carbon to the atmosphere.…”

The terrestrial sediment cycle is not in equilibrium. Agriculture, civil engineering, and mining mobilize vast quantities of soils, unconsolidated sediment, and bedrock, perhaps more than all natural geomorphic processes combined [Hooke, 1994]. The hydraulic architecture of the land has been transformed to serve agriculture, water supplies, land reclamation, navigation, and power generation. Few rivers lack dams and reservoirs; large rivers are confined to their channels by levees; normal floodplains are converted to paddy lands and aquiculture; water is mined; irrigation raises soil moisture and creates artificial distributary systems, and so forth. Agriculture has transformed a large Ëaction of the 231

“…Without detailed, region-specific measures of aboveground and soil C and N pools, regional estimates of the dynamics of such pools will be superficial at best, and inaccurate and misleading at worst, because the distribution of both C and N pools among tropical forest ecosystems varies substantially as a function of soil type, climate, and land use and land cover conditions (Detwiler, 1986;Schlesinger, 1986;Brown et al, 1993;Hughes et al, 1999;Hughes et al, 2000). While the numerous studies relevant to C and N dynamics conducted to date in Costa Rica aid the construction of C and N budgets in ecosystems across the nation, these studies are not sufficient to accurately estimate regional C and N stocks in vegetation and soils.…”

Policy enabling tropical forests to approach their potential contribution to globalclimate-change mitigation requires forecasts of land use and carbon storage on a large scale over long periods. In this paper, we present an integrated modeling methodology that addresses these needs. We model the dynamics of the human land-use system and of C pools contained in each ecosystem, as well as their interactions. The model is national scale, and is currently applied in a preliminary way to Costa Rica using data spanning a period of over fifty years. It combines an ecological process model, parameterized using field and other data, with an economic model, estimated using historical data to ensure a close link to actual behavior. These two models are linked so that ecological conditions affect land-use choices and vice versa. The integrated model predicts land use and its consequences for C storage for policy scenarios. These predictions can be used to create baselines, reward sequestration, and estimate the value in both environmental and economic terms of including C sequestration in tropical forests as part of the efforts to mitigate global climate change. The model can also be used to assess the benefits from costly activities to increase accuracy and thus reduce errors and their societal costs.

“…For humus and dinert carbon this type of structure can be derived from the work of Kortleven (1963) and of Olson (1963), who both showed that the response of humus level to litter input is of a first order character. Schlesinger (1986) reviewed several data sources, leading to support of first order dynamics of humus. He mentioned considerable losses in soil carbon upon reclamation of virgin land (from an equilibrium of 20 kg C m-2 to a new equilibrium of 15 kg C m-2 , to be reached after several decades).…”

Modelling biospheric control of carbon fluxes between atmosphere, ocean and land in view of climatic change

ABSTRACT. The ~aunt of carbon in the atmosphere is less than in the terrestrial biosphere and much less than in the ocean. The level of atmospheric COz is the result of a delicate balance in exchange fluxes with ocean and biosphere. Climatic change has the potential to alter this balance.A model for the global carbon cycle was used for assessment of the importance of a number of biosphere and ocean characteristics that control atmospheric COz. This model included COz feed back on the exchange fluxes, but no temperature feed back.According to this model covering previously bare land with vegetation would lower atmospheric COz by only 1.5 ppm for each 10 12 m 2 (100 Mha) of land additionally covered. At the present size of the terrestrial biosphere a global doubling of longevity of soil carbon would cause a decrease of 65 ppm of atmospheric COz.The accumulated net biospheric release of carbon to the atmosphere during the last 120 years is estimated at about 30 Gt c. This figure is consistent with measured data of carbon isotopes and with data of atmospheric COz. Marine photosynthesis is responsible for building up high phosphate and carbonate levels in the deep sea)?Y precipitation of organic material. Marine photosynthesis is mostly limited by phosphate in the surface waters, and therefore an increase in total phosphate in the sea would lower atmospheric COz. Precipitated fraction and phosphate content of organic material are equally important.The present difference in chemical composition between the Atlantic ocean on one hand and the Indian and Pacific oceans on the other can be explained by a much larger mixing rate between deep and surface water in the Atlantic ocean. Reducing this mixing rate in the Atlantic to that in the Pacific, would cause atmospheric COz to drop by 25 ppm within a few hundred years time. Similarly, a sudden increase in m1x1ng rate at the glacial-interglacial transitions could explain the strong and fast rise in atmospheric COz.
