It also fuels mistrust which hinders long-term investments and restricts possibilities for gaining funding from the traditional banking sector which finances practically all working capital, infrastructure works and machinery and equipment purchase. In addition, and under agreements between the international NGO Rainforest Alliance and the government, and in programmes such as those implemented by the Inter-American Development Bank (IDB) in conjunction with Grupo Financiero de Occidente (FIDOSA), medium-term financing mechanisms have been adopted along with technical assistance giving access to credit for the forestry sector. Nonetheless, concessions displaying a poor economic performance have slim chances of benefiting from such mechanisms. The Central National School of Agriculture (ENCA) offers specialist technical courses leading to the qualifications of Forestry Expert and Technician in Conservation and Management of the Tropical Forest.
