In this research there appear the potentialities of the fruit and powder of divi–divi as: water–based drilling fluids (WBDF) environmentally friendly deflocculant, leguminous fodder for ruminants and sustainable jobs in farm communities, able to influence the primary forests protection. Tannins extract in the form of divi–divi fruit powder (Caesalpinia coriaria), contains 47.0 wt % of total tannins (hydrolysable tannins plus condensed tannins) of which 30.0 wt % corresponds to hydrolysable tannins. Divi–divi tannins in WBDF showed nine (9) times deflocculant efficiency than heavy metals commercial modified tannins. Moreover, commercial modified tannins do not improve their deflocculant efficiency with increased tannin content. Bromatology and structural analysis of fruits (wet base), they show it as a maintenance fodder: 5.33 % w/w crude protein, 9.68 wt % moisture, 77.03 wt % nitrogen–free extract (NFE) (Weende Method), 11.38 wt % neutral detergent fiber (NDF) and 5.52 wt % acid detergent fiber (ADF) (Van Soest method). Social–productive production of 15 divi–divi tannins in artisanal way with help of rural community Boquerón, belonging to the municipality Pedro María Freites of Anzoátegui state, there served as developing socially productive pilot model that as well as beneficial at 245 families, whose raw material is conceived as non–wood forest products (NWFP), improve the sustainable utilization of NWFP in order to contribute to the wise management of the world’s forests and to improve income generation and food security.
