Resumen
Descripción
Mato Grosso do Sul State has about 20 million hectares of pastures (SIGA-MS, 2016). From this total, close to four million hectares are natural grasslands in the Pantanal wetlands. The balance, or about 16 million hectares, are sown pastures. The State Secretary of Agriculture (Secretaria de Estado de Produção e Agricultura Familiar - SEPAF) estimated that at least 50% of the total cultivated pasture are degraded or with some degree of degradation. These areas have low productivity and may negatively affect environment. To face the problem of degraded pastures, SEPAF created the “Terra Boa Program” focused on the improvement of pastures in Mato Grosso do Sul (SEPAF, 2016). The Program aims “to promote, within five years, restoration and maintenance of production capacity for two million hectares of degraded pastures in the state”. The Program addresses seven major actions: (i) improvement of pastures; (ii) conversion of pastures into cropland; (iii) integrated crop- livestock systems; (iv) integrated crop-livestock-forestry systems; (v) integrated livestock- forestry systems; (vi) conversion of pastures into sugarcane farming; and (vii) afforestation.
