Query and decision-making support tool, based on the elaboration of cultivation scenarios for the following tropical grasses, cultivated in Brazil: Brachiaria brizantha cv. Marandu, Panicum maximum cv. Tanzania, Cenchrus ciliris, Opuntia sp. and Lolium multiflorum. From data resulting from the simulations, it is possible to evaluate possible scenarios for such grasses in different regions of the country. By anticipating risks, these scenarios can contribute to the suitable planning of livestock production activities and to the adoption of alternatives to adapt to possible environmental change, reducing their potential impacts on this kind of exploitation, and also as an aid for government programs. This technological solution was developed by Embrapa in partnership with other institutions.
