Abstract
The study was carried out in Kiramuruzi, Gasange and Kabarore Sectors of Gatsibo District in Rwanda with the aim of valuing the soil conservation benefits of agroforestry practices Reconnaissance survey, direct observation, key informant interview, questionnaire survey with schedule, and group discussion were used for primary data collection where purposive and random sampling were used. Gender and age groups were selected as sample household for interview. Secondary data were gathered from District Forest Office, NGOs, libraries, journals and magazines. Descriptive statistics was carried out and the results were summarized in graphs and tables. The results showed that land was found to be scarce mainly due to population pressure. However, the majority of farmers’ own land that ranged from 1 to 3 ha where fodder trees were found to be the most common which was 94.4%, 85.4% and 81.25% of respondents from Kiramuruzi, Kabarore and Gasange sectors respectively, followed by fruit trees (94.4%, 82.9% and 81.25%) and timber trees (50%, 51.2% and 67.8%). The most common tree species were Calliandra spp. Eupatrium spp, Saccharum spp, Imperata sppl, Cedrela spp, Grevillea r Leucaena spp, Mimosa spp, Moringa spp and Alnus spp. In conclusion, agroforestry provides all types of forest products needs of households and is appropriate for the control erosion, to maintain soil fertility, and efficient nutrient cycling, vegetative cover and the improved animal diversity.
