But neither Mulato nor Mulato 2 are tolerant to waterlogging conditions. Recently, CIAT initiated efforts to breed for superior Brachiaria humidicola hybrids. These hybrids are required to diversify pastures in poorly drained or occasionally waterlogged soils that are estimated to cover about 7 per cent of the Cerrados (savannah) region of Central Brazil (approx. 17 million hectares) and major cattle production regions in the Amazon and the Atlantic regions of Central America. This work has been partially supported by the Ministry of Agriculture and Rural Development of Colombia and the private sector (Tropical Seeds; Dow AgroSciences).

Deep rooted Brachiaria grasses accumulate large amounts of carbon in deeper soil layers and contribute as such to mitigation of climate change. Forages can also contribute to the reduction of greenhouse gas emissions: feeding high quality forage grasses reduces methane emissions from animals per unit livestock product, whereas some Brachiaria grasses (such as B.
