O açaí já “parou” o carioca?: estudo qualitativo do consumo da polpa de açaí na cidade do Rio de Janeiro
(1999-12) GUIMARÃES, Luís Alfredo Chrysostomo
Esse artigo apresenta os resultados de uma pesquisa realizada na região amazônica, a qual tem por objetivo estudar a valorização de frutas tropicais pela agricultura familiar, e dentre estes apresenta o açaí (Euterpea oleracea mart.), um fruto de alto consumo na região norte do país, principalmente no Estado do Pará, que é o maior produtor e consumidor dessa fruta no Brasil. Indica formas de melhor apropriação por parte dos agricultores na venda de sua produção. Sugere a agregação de valor a esse fruto, através de um processo de beneficiamento a ser desenvolvido a partir de uma cooperativa de agricultores organizados. Desenvolve a análise a partir da expansão do uso do suco desse fruto em outras regiões do Brasil, especificamente na cidade do Rio de Janeiro, a qual já vem apresentando aumento significativo de consumo nos últimos seis anos.

Agricultura familiar e desenvolvimento rural sustentável na Amazônia
(2005-06) HURTIENNE, Thomas Peter
The article presents a critical review of theoretical and methodological concepts upon which analytical works about Amazonian peasantries since the 1960s have been based. The vision of Amazon peasants as shifting cultivators with low productivity who destroy their ecological habitat and are condemned to disappear due to the advance of large landowners (the model of the frontier cycle) is contrasted with the tendency for the consolidation of family agriculture based on more complex production systems, including permanent cultures, small animal husbandry and cattle. This tendency is more clearly evident in the Northeast of Pará, but has also been statistically confirmed for the State of Pará and the Northern Region of Brazil. This means that the hypothesis of the frontier cycle has limited validity for older colonization regions. However, recent research on borders showed production systems which concentrate on cattleraising in the South of Pará and on permanent cultures in the Transamazônica region. These systems cannot simply be classified as shifting cultivation but represent different trajectories from that of the Northeast of Pará.

Análise socioeconômica dos sistemas de uso de terra por pequenos produtores agrários na Amazônia oriental
(2004-12) HURTIENNE, Thomas Peter
This article examines the dynamics of agricultural systems used by small farmers in the northeast of the State of Pará (Brazil). Its goal is to relate specific forms of shifting cultivation and extractive industry in Amazonia with endogenous processes of economic decision making. It has resonated on the system dynamics, and public policies, which as of the 70’s have focused on agricultural modernization and creation of permanent crops, thus contributing to the achievement of agro-ecologic and agro-economic barriers. Based on the new dynamics, small family enterprises in Amazonia have to cope with public and private actions, which undermine their stability.

Beneficiamento local da produção extrativista e agroflorestal: o caso da Cooperativa Agroextrativista de Xapuri – CAEX
(2000-12) MICHELOTTI, Fernando
The main purpose of this paper is to elucidate the difficulties faced by Cooperativa Agroextrativista de Xapuri (Xapuri Agroextrativist Cooperative) to achieve its economical viability. Created in 1988 by the rubber tapers from Xapuri (Acre/Brazil), its case study provides an interesting example of an attempt to establish a local agro-extrativist production processing project. This project aimed to aggregate value by processing its members´ Brazil nuts production. The economical return of this iniciative, however, turned out to be less than the expected. Most of the studies dealing with the evaluation of these poor economical results identified as the main causes isolated socioeconomical factors happening in the production and comercialization process. Using conceptual framework of the evolutionary economy,this study pursues the identification of others structural problems as the primary causes leading to this bad economical return.

A crise ecológica na agricultura familiar do Estado do Maranhão: contribuições para um debate
(1999-12) FREITAS, Antônio Carlos Reis de
Este texto tem o propósito de apresentar uma análise sócio-econômica e ecológica das transformações históricas que afetam as unidades econômicas camponesas no Estado do Maranhão. Os dados oficiais disponíveis permitem inferir a existência de uma crise ecológica que ameaça a sustentabilidade das mesmas. A reversão desse processo requer o desenvolvimento de pesquisas que qualifiquem o conjunto dos problemas existentes e desenhem uma matriz de indicadores de sustentabilidade para viabilizar a reestruturação tecnológica dessas unidades produtivas. Neste sentido, esta reflexão, parte de uma pesquisa em andamento, tem a pretensão de subsidiar a intervenção dos atores sociais e das instituições governamentais envolvidas no processo da reforma agrária no Brasil.

A dinâmica dos sistemas de produção, as estratégias de intensificação e o papel da tecnologia de mulch na economia familiar
(2004-06) FIGUEIREDO, Raul Batista de; HURTIENNE, Thomas Peter
Family agriculture in Cumaru, northeast of the State of Pará, established through spontaneous settlements, is a dynamic agriculture, formed through an internal development process and the migration of individuals from the northeast of Brazil. Our study evaluates the use of non-burning techniques in the development of production systems, analyzing the evolution of family establishments in Cumaru, their intensification strategy, and most particularly, the role of mulching and enrichment in family economies.

Mercado e potencialidades dos produtos oriundos de floresta secundária em áreas de produção familiar
(2009-12) COSTA, Francisco de Assis; BRIENZA JÚNIOR, Silvio; MELLO, Denyse Gomes
This article highlights the role of store of value and of agent foster of rural income of secondary forests, also known as “capoeira” (brushwood), often confused with degraded areas, with no economic or ecological function. The importance of the secondary forests - which increasingly dominate the scenario of family agriculture of the Brazilian Amazon – as a productive factor here was studied through the identifi cation and description of the supply chains of products from secondary forest and opportunities for development of these chains for farmers in the municipalities of Bragança, Capitão Poço and Garrafão do Norte. The established supply chains are simple, and the main products identifi ed are grouped into categories of fruit, timber, derived from animal and medicinal plants. It was concluded that the secondary forests proved to exert a key role in maintaining biodiversity and in the regeneration of anthropized ecosystems, and contribute in the income of farmers.

PATH dependency e a transformação agrária do bioma amazônico: o sentido econômico das capoeiras para o desenvolvimento sustentável
(2004-12) COSTA, Francisco de Assis
The “capoeiras” - altered soils by antropic action that are in expontaneous process of regeneration of its forest covering - are component of the rural landscape of great meaning in the Amazonian. In the last Agricultural Census, the areas of capoeira amounted 4,5 million hectares in the whole North Region of Brazil. A increasingly important literature considers such areas indicator of decadent and unsustainable rural economies, on which rises a pressumably efficient and sustaintainable livestock for meat production. This article tries to establish the different capoeira’s types that exist in the Amazonian’s rural economy, relating them to the different production forms, whose systems are dinamicaly expressed as competitive technological paths. On that base it demonstrates a) that part of those areas results of positive changes in the productive systems that produce “capoeiras” with great regeneration capacity - being associated, therefore, to important innovations for the development of the Region in a perspective that incorporates criteria of environmental sustainability; b) that the types of “capoeiras” that indicate land degradation, because of their low regeneration capacity, associate to the cut livestock, which has been presenting structural difficulties of technical modernization. The article indicates also that the prevailing institutional environment, favoring the systems that produce degraded “capoeira” in detriment of those that produce “capoeiras” of fast regeneration, can arrest (to take it into a lock-in) the agrarian economy of the Region in the worst solutions in economical, social and ecological meaning.
