Peasants in the Tahuayo River basin near Iquitos, Peru earn cash incomes from swidden fallow, agroforestry, floodplain agriculture, fishing, livestock production, hunting and extracting rainforest products. Gross returns per hectares were highest
for fishing, floodplain agriculture and upland agroforestry. In this article, the A. conducts a first-class survey and asks probing questions about how peasant livelihoods can be studied. - (DWG)
The paper compares alternative regulating systems: dualism or the currently practised 35/65 percentage share between offshore trawlers and coastal fishing boats, boat quotas, group quotas, company quotas, individual quotas, tradable quotas and area
