Report 08. The pole market in Haiti : southwest to Port-au-Prince 
Street, Donald R.; Bellerive, Phillippe (2019-04-23)
The purpose of this work was to analyze the pole market in Port-au-Prince. The study entailed taking samples of 25 randomly chosen poles at seven depots in the metropolitan area and tracing their movement from their origin. ...
Report 09. Socio-cultural factors in Haitian agroforestry: research results from four regions 
Starr, Paul D. (2019-09-03)
This report presents the results of research on socio-cultural aspects of agroforestry in the Des Forges, Bassin Bleu, Vialet and Maniche areas of Haiti. A total of 258 households were surveyed, 108 in Bassin Bleu and fifty ...
Report 10. Impact des haies vives sur la production agricole 
Rousseau, Pierre M.; Hunter, Arthur Gene; Enilorac, Marie-Paule (2019-10-03)
Declining yields and land degradation are becoming more dramatic every year in spite of increasing foreign aid. Population growth far exceeds food production capacities. However, the effects of all agricultural development ...
