Application of hexagonal two dimensional electrokinetic system on the nickel contaminated sediment and modelling the transport behavior of nickel during electrokinetic treatment. 2 Carbon gain from tropical forest restoration by 2100. Deforestation takes place to turn forests into agricultural land for the production of commodities like palm oil and cattle, for mining, or to make way for new infrastructures like roads and dams. As for traditional landfills, composting, and other sediment disposal processes, the moisture content of sediment should be frequently reduced to less than 60%. There now should be no debate that the threat of catastrophic fire is the most significant environmental challenge facing California's forests and wildlands. It also clears roadblocks that prevent much needed action on the ground, streamlining the appeals process and procedures within federal agencies that manage federal forestlands while encouraging public participation early in project planning.
