Desenvolvimento sustentável e uso dos recursos naturais em áreas de várzea do território do baixo Tocantins da Amazônia paraense: limites, desafios e possibilidades
(Universidade Federal do Pará, 2016-06-19) REIS, Adebaro Alves dos; ALMEIDA, Oriana Trindade de; http://lattes.cnpq.br/0325909843645279
The central goal of this thesis is to understand and analyze the dynamics of sustainable use the natural resource by the cabocla-riverside populations aiming the application of sustainable development concept and, starting the observation the everyday the way of life, the use of natural resources and the process of diversified production as empirical elements required to think a new pattern of development, in other words, the sustainable, anchored to traditional knowledges of cabocla-riverside populations of lowland areas the territory of Baixo Tocantins of Amazon Paraense. Like this, sought , starting of theoric debate, develop a criticizes to modern science, with specificity to instrumental rationality, that promoted fragmentation the relationship between man and nature, through development of destructive activities the natural resources that compromise the own human life , the same time, was introduced an approach of interdisciplinarity as one possibility of articulation in different areas of knowledge for a intervention under perspectives of dimensions the social life and natural. The study to elaborate this thesis has as universe the Baixo Tocantins territory, where it considered the lowland ecosystems of municipalities Abaetetuba and Igarapé-Miri, in their components considered strategic like: riverside communities, agro ecosystem and riverside population, constitutive the Tocantins river margin. For this, was reconstituted of synthetic mode, the historical trajectory of this territory through of occupation, development, and use of natural resources, which were analyzed from adaptive productive dynamics , and use of natural resources in their multiple activities of management of lowland ecosystem focused for production and management of açaí , agroforestry systems (SAFs), agriculture, creating of small and medium-sized animals , creation of fishes, vegetal extractivism and animal , shrimp fishery and fish on lowland ecosystem. This practices of use the natural resources, traditionally employed by inhabitants of lowland areas makes part of one lifestyle, that secularly has guaranteed the production of knowledge acquired/inherited of past generations, how management and use nature resources of this agrosystem. The productive diversity strategies, management and multiple uses the nature resources follows the rhythms imposed by nature of adaptation capacity of relation with natural conditions of lowland areas, such as : flood process, flood and ebb the rivers, erosion/ deposition , environmental impacts by great developmental projects, elevated levels of the rivers , among others factors, keeping a high degree of interrelationship balanced with nature. Can mean that, in the lowland ecosystem, man and nature are completed, creating a single standard of sustainable development.

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.

Planting coconuts in Indian villages: ethnoecological aspects and evaluation of a "sustainable development" project
(2010-03) SALM, Rodolfo Aureliano; FEDER, Lisa; JALLES FILHO, Euphly; JARDIM, Mário Augusto Gonçalves
Although scientists and policy makers embrace the general concept "sustainable development", there are few who agree on how to carry out sustainable development in specific situations. As such, sustainable development projects among ethnoscientists are widely critiqued as to how well they are inter-culturally formulated. Here we report on a controversial case of planting coconuts in Kayapó Indian villages of southern Pará, Brazil and offer our own self-critique. We began under the premise that reforestation and Kayapó general health/nutrition go hand in hand. Therefore, the flourishing of coconut culture will contribute to forest conservation in the long run, in itself, and simultaneously, maintain good nutrition for the Kayapó people who protect the forest from the threat of non-sustainable practices. We take an ethnoecological approach in discovering how Kayapó behavior affects the growth and flourishing of coconut culture when fostered with external supply. We present the results of two field trips to the Kayapó indigenous territory, where we found socio-ecological factors relevant to the success of our project supporting the culture of coconuts in indigenous villages. First, in November 2007, we visited Kikretum, Moikarakô and Aukre villages (among 10 villages which received coconut seedlings from our support program) to deliver a second shipment of coconut seedlings (the first shipment to these villages took place in April 2006) and quantitatively described one aspect of coconut seed-disperser's (the Kayapó's) behavior. We looked specifically at how the pre-existing coconuts palms were distributed among the Indian families, how they distributed last year's shipment, and how that shipment survived due to ethnoecological factors. Second, in July 2008 we visited Kokraimoro and Pykararankre villages and estimated the position of the previously existing and newly planted coconut palms in relation to other cultivated trees by making use of censuses departing from the village center to their outside limits. In the three Indian villages we visited in 2007, virtually all pre-existing coconut trees belonged to a select few families, and the coconut fruit distribution was, in most cases, highly concentrated among these family members. However, assuming that all the coconut saplings that survived the first year will reach maturity (from the first shipment in April 2006), they represent a remarkable increase in the projected number of adult coconut palms in the three visited villages (48, 195 and 101% in Kikretum, Moikarakô and Aukre, respectively), and a substantial reduction in the inequality in access to coconuts. In the 2008 field trip, we found that the Indians usually plant coconuts very close to their houses where competition with other cultivated trees may hinder the palms development.
