    Notes: Abstract Many of the processed palm hearts consumed throughout the world are derived from the açaípalm (Euterpe oleraceaMart.)), which grows abundantly in floodplain forests of the Amazon estuary. Palm heart extraction began in the estuary in the 1970s and there are now hundreds of canning factories and some 50 distribution firms in this region. Annual profits of the canning factories range from $30,000 to $50,000 while profits for distribution firms frequently exceed $500,000/year. But there are several indications that this economic boon will be short-lived: factory closings are frequent, palm hearts are much smaller now than in the past, and mortality of palm trees is high in stands subjected to frequent palm heart harvest. However, the açaípalm is well suited for management because of its abundance, rapid growth, and multistemmed life form. Under management, palm hearts can be harvested from the same clump over many years through controlled thinning. The management of açaístands could result in significant long-term savings for palm heart factories. Indeed, açaímanagement may offer one of the best opportunities to date for sustained use of some Amazonian forests.

    Settler agriculture and the dynamics of resource allocation in frontier environments (1996)
    Springer

    Notes: Abstract This article attempts to conceptualize the dynamics of resource allocation by colonist farmers under the unique conditions of land abundance and labor scarcity which characterize frontier environments, such as the smallholder agricultural settlement areas in the Amazon basin. In contrast, most previous theoretical literature on household agricultural decision making and land-use change in rural areas considers conditions of high population density and land scarcity, and is not, therefore, adequate for understanding critical land-use changes which may be occurring in frontier regions. This article first discusses the appropriateness and inadequacies of the analytical frameworks commonly used to explain the expansion of settler agriculture into remote forest regions and the unsustainable land-use practices observed in these areas. This review serves as the basis for characterizing resource allocation under the particular conditions of frontier environments. A conceptual advance in the analysis is its consideration of the way institutional/policy factors and farm-level characteristics can interact to produce land-use outcomes. This knowledge is essential to understand not only the social and economic factors affecting present land use and choice of technology, but also those factors influencing farmers' demand for more optimal systems of land use which are consistent with varying agro-ecological potentials, demographic situations, and their own management capacity.
