Demographic and migration characteristics of riberenos , the largest population group in the Amazon Basin, have been neglected by scholars until recently. This thesis explores the determinants and consequences of migration in the Pacaya-Samina National Reserve (PSNR), northeastern Peruvian Amazon. Our findings suggest that migration reduces the rate of population growth and alters household composition. Logit and probit models show that migration in the area is determined by individual characteristics (i.e., education level of migrants and sibling structure), household factors (i.e., family age-sex composition, kingroup size, age of male head of household, education level of male and female heads of household, illness experience, initial extraction skills, initial non-land assets, and livelihood activity reliance), and community features (land endowments and the presence of a secondary school). Multiple regressions (OLS) further reveal that the household age-sex composition and migration characteristics influence resource use. Migration features seem to be more positively associated with agricultural production and resource extraction, and negatively related with fish production. This research improves our understanding of traditional people in the PSNR area.

Researchers recognize the need to better understand the factors influencing indigenous land use in order to design sustainable tropical forest management programs. A key relationship that has been long overlooked in peasant societies is the one between communal labor access through social networks and land acquisition/accumulation. This study examines land distribution and labor patterns in traditional agriculture of a lowland and a upland community on the Maranon River near Iquitos, Peru. Data were gathered through household interviews (n=76) and field visits (n=396) between June and November 2001. Results reveal marked variations in access to land and communal labor between and within communities. Household age, initial land wealth and initial inputs of labor are crucial in explaining land and labor inequalities within villages. This research contributes to a better understanding of the factors that give rise to local heterogeneity in wealth holdings and livelihood strategies, necessary tools to promote conservation throughout the region and beyond.
