Advances in economics studies of agroforestry plantations in Central America Proceedings

by Fassbender, H.W; Heuveldop, J. eds; Reiche C, C.E; Beer, J.W; CATIE, Turrialba (Costa Rica); GTZ, Eschborn (Alemania); Advances in Agroforestry Research Turrialba (Costa Rica) 1-11 Sep 1985.
Series: Serie Técnica. Informe Técnico (CATIE).Publisher: Turrialba (Costa Rica) 1987Description: p. 338-346.Subject(s): ARBOLES Y CULTIVOS ANUALES | PLANES, PROGRAMAS Y PROYECTOS | PLANTACION | CERCAS VIVAS | LEÑA | ECONOMIA | EUCALYPTUS | ZEA MAYS | GLIRICIDIA SEPIUM | AMERICA CENTRAL | PLANTING | ECONOMICS | EUCALYPTUS | ZEA MAYS | GLIRICIDIA SEPIUM | CENTRAL AMERICA | PLANTATION | ECONOMIE | ZEA MAYS | GLIRICIDIA SEPIUM | AMERIQUE CENTRALE In: Summary: In the Central American Isthmus, firewood represents more than 50 percent of the energy used. The "Firewood Project" of CATIE has promoted the establishment of agroforestry demonstration units which are regularly assessed and given a silvicultural follow-up, and in some cases are economically evaluated. The intention is to increase production levels and the net incomes of the producers. The implementation of simple and practical methods, for registering costs and incomes, has shown that for agroforestry programmes in Costa Rica it is cheaper to produce seedlings in temporary nurseries than in permanent nurseries ( 40 and 47 per 1000 trees, respectively). The plantation estabishment costs vary from country to country and with respect to: slope, stoniness, number of trees, presence of secondary vegetation, fence costs, and the use of other materials. In a case study of the agroforestry system Eucalyptus saligna and Zea mays, the internal rate of return was 20.15 percent. In a case study of Gliricidia sepium living fence posts it was 6.19 per cent. The preliminary financial indicators show that the production of firewood from agroforestry systems is a viable alternative which can generate financial returns.
