“…In the last 60 years, large dams were constructed along the São Francisco River to produce hydroelectric energy, such as the Sobradinho Lake Hydroelectric Dam, the Moxotó Power Station and the Paulo Afonso Power Stations (I, II, III and IV) in the municipality of Paulo Afonso [ 53 ]. The construction of the last dams resulted in the violent eviction of the Indigenous people from their lands [ 54 ] and constituted the human intervention that most impacted the São Francisco River basin and its surroundings [ 55 ].…”

Assessing the Effects of Indigenous Migration on Zootherapeutic Practices in the Semiarid Region of Brazil

et al. 2016

Human migration implies adaptations to new environments, such as ways to benefit from the available biodiversity. This study focused on the use of animal-derived remedies, and we investigated the effects of migration on the traditional medical system of the indigenous Truká people. This ethnic group lives in Northeast Brazil and is currently distributed in four distinct villages. In these villages, the zootherapeutic knowledge of 54 indigenous people was determined through semi-structured questionnaires given from September 2013 to January 2014. The interviewees indicated 137 zootherapeutic uses involving 21 animal species. The variety of species and their uses have a higher similarity between villages that are closer to each other, which can be a reflection of geographic and environmental factors. However, even close villages showed a low similarity in the zootherapeutic uses recorded, which reflects a strong idiosyncrasy regarding the knowledge of each village. Hence, each village may be influenced by the physical environment and contact with other cultures, which may maintain or reduce the contact of younger villages with the original village.

“…These studies are being complemented (or partly repeated) by a nationwide program to monitor the Brazilian biomes on an annual basis, which has been set up in 2015 by a group of NGOs, universities, and companies. Concrete efforts in restoration of riparian vegetation and areas around sources have been initiated by the committee of the São Francisco River Basin as a response to land use changes for water diversion at large scale (Machado 2008), which has been institutionalized later on. This committee has a budget due to the payments for water abstraction.…”

A multi-method approach to explore environmental governance: a case study of a large, densely populated dry forest region of the neotropics

Semiarid regions are often secondary on the national to global (scientific) agenda, especially if abundant vegetation elsewhere draws attention and the local population is considered backwards thinking and poverty-stricken. The Caatinga, our case study, is such a region, home to millions of Brazilians and a vast biodiversity. Unfortunately, a widely uncoordinated land use change and biodiversity decline are happening, while farmers' livelihoods are at risk. We hypothesize substantial weaknesses in the current governance practices. To explore governance of the less noticed region, we conducted interviews and field visits and complemented the findings with the literature and internet resources. Our multi-method approach combines the social-ecological systems framework with constellation analysis and dynamic modeling. The aim was to understand the current state of governance in the region and identify clues for more sustainable land management. The use and conservation of Caatinga are negotiated at multiple levels, which are only sporadically interlinked. The conversion of forest land into alternative land uses shifts and shares responsibility among different sectors, while cross-sectoral cooperation is rarely observed. The region and its population face massive prejudices. Obstructing attitudes, such as thinking in dichotomies, and paternalistic and opportunistic approaches, are being addressed by some new coalitions taking alternative action. It is unlikely that these isolated initiatives will converge by themselves to a larger transformation toward sustainable resource use. There is a need to bring the dispersed actions in a more focused and coordinated approach, integrating socioeconomic and ecological concerns, values, and partnerships.

“…According to MACHADO (2008), the merits of the project was to introduce the idea of revitalizing watersheds in the role of public policy under the responsibility of the Union, States and municipalities. However the greatest positive impact of the project is to consolidate the greater movement in the history of Brazil in favor of a river.…”

ABSTRACT:The transposition of the São Francisco River is considered one of the greatest engineering works in Brazil of all time since it will cross an extensive agricultural region of continental dimensions, involving environmental impacts, water, soil, irrigation, water payment and other multidisciplinary themes. Taking into account its importance, this subject was incorporated into a discipline of UFSCar (Federal University of São Carlos -Brazil) named "Pollution and Environmental Impacts". It was noted strong reaction against the project, even before the presentation. To allow a critical analysis, the first objective was to compile the main technical data and environmental impacts. The second objective was to detect the three most important aspects that cause reaction, concluding for the following reasons: assumption that the volume of water to be transferred was much greater than it actually is proposed in the project; lack of knowledge about similar project already done in Brazil; the idea that the artificial canal to be built was much broader than that proposed by the project. The participants' opinion about "volume to be transferred" was raised quantitatively four times: 2-undergraduate students; 1-graduate; 1-outside community. The average resulted 14 times larger than that proposed in the project, significant according to t-test. It was concluded that the reaction to water transfer project is due in part to the ignorance combined with a preconceived idea that tend to overestimate the magnitude of environmental impacts. KEYWORDS:Integration, water transfer, volume, technical data, Northeast, semiarid. TRANSPOSIÇÃO DO RIO SÃO FRANCISCO PARA O NORDESTE SEMIÁRIDO DO BRASIL: DADOS TÉCNICOS, IMPACTOS AMBIENTAIS E ENQUETE SOBRE O VOLUME TRANSPOSTORESUMO: A transposição do Rio São Francisco, uma das maiores obras de engenharia do Brasil de todos os tempos, cortará uma extensa região agrícola de dimensões continentais, envolvendo temas de caráter multidisciplinar, como impactos ambientais, água, solo, irrigação, outorga de água e outros. Devido a sua importância, incorporou-se a partir de 2005 o tema a uma disciplina denominada Poluição e Impactos ambientais, UFSCar. Mesmo antes das apresentações verificava-se forte oposição. Preliminarmente, o objetivo do trabalho foi levantar os principais dados técnicos e impactos ambientais, culminando com uma análise crítica sobre a obra. O segundo objetivo constituiu-se em detectar no público participante das exposições os três aspectos mais relevantes que causavam oposição, concluindo-se pelas seguintes razões: a pressuposição de que o volume de água a ser transferido seria muito maior do que na realidade se propõe no projeto; o desconhecimento de outras obras de transposição em operação no Brasil e a ideia de que o canal artificial teria largura muito maior do que o proposto. Quanto ao item volume a ser transferido, levantaram-se quantitativamente os valores imaginados pelos participantes em quatro apresentações (cursos de graduação-2, curso de pós-graduação-1 e apresent...
