As with plants this means more photosynthesis it means more biomass production and a higher CO2 uptake.

Yet if those plants were going to grow anyway (e.g., for food), simply diverting them to bioenergy does not remove any more carbon from the atmosphere and therefore does not offset emissions from burning that biomass.

Feedstocks can include more durable material such as woody biomass and wastes that are not broken down in traditional anaerobic digester plants.

Many biomass cogeneration plants and small hydropower plants are already in operation in Brazil, and more are under construction.

Biomass power plants do emit carbon dioxide, a greenhouse gas, but they release no more than what is naturally in the carbon cycle as trees are planted, downed — by man or nature — and replanted.

This greater plant growth means more carbon is stored in the increasing biomass, so it was previously thought the greening would result in more carbon dioxide being taken up from the atmosphere, thus helping to reduce the rate of global warming.

Where precipitation decreases were projected, the results were more complex due largely to interactions between plant biomass, runoff, and erosion, and either increases or decreases in overall erosion could occur.

This spurs higher rates of photosynthesis and biomass production, so the plants produce more sediment - trapping growth above ground and generate more organic soil below ground.»

Increased weed and pest pressure associated with longer growing seasons and warmer winters will be an increasingly important challenge; there are already examples of earlier arrival and increased populations of some insect pests such as corn earworm.64 Furthermore, many of the most aggressive weeds, such as kudzu, benefit more than crop plants from higher atmospheric carbon dioxide, and become more resistant to herbicide control.72 Many weeds respond better than most cash crops to increasing carbon dioxide concentrations, particularly «invasive» weeds with the so - called C3 photosynthetic pathway, and with rapid and expansive growth patterns, including large allocations of below - ground biomass, such as roots.73 Research also suggests that glyphosate (for example, Roundup), the most widely - used herbicide in the United States, loses its efficacy on weeds grown at the increased carbon dioxide levels likely to occur in the coming decades.74 To date, all weed / crop competition studies where the photosynthetic pathway is the same for both species favor weed growth over crop growth as carbon dioxide is increased.72
