Involving local and indigenous populations is key to effective environmental governance

The Tucson metropolitan area, located in the Sonoran Desert of southeastern Arizona (USA), is affected by both massive population growth and rapid climate change, resulting important land use cover (LULC) changes. As its fragile arid ecosystem scarce resources are increasingly under pressure, there a crucial need to monitor such landscape transformations. For ends, we propose method compute yearly 30 m resolution LULC maps region from 1986 2020, using combination Landsat imagery, derived...

A ação do INCRA na Amazônia revela um paradoxo: por mais que a ocupação humana daquela região fosse uma estratégia dos governos militares, é fase democrática recente reforma agrária brasileira intensifica instalação de agricultores em assentamentos. institucionalização políticas proteção meio ambiente se contraditória com as práticas social têm, Amazônia, foco destaque num modelo provoca inevitáveis consequências ambientais.

The Amazon forests, the Northern artic regions, Australian bush and Siberian plains all have very low demographic densities, but they are rarely studied as pertaining to same global category. It appears, however, that when considering sparsely populated regions (SPR) globally share not only demographical characteristics, also a number of features in their economic, political, spatial social configuration, more importantly visions nature environment, which make them different from densely...

Study of the spatial patterns land use and forest resource exploitation by a Yanomami community in northern Amazonia (Brazil) combining high‐resolution satellite imagery global positioning system survey data with ethnogeographic fieldwork shows that its natural‐resource is configured terms "reticular space" rather than set discrete concentric "zones." This model reticular space has general relevance for other Amazonian indigenous groups. The research reported demonstrates value...

In April 2017, Suriname's Ministry of Health alerted French Guiana's Regional Agency (RHA) about an increase imported malaria cases among people coming from illegal gold mining site called Sophie, in Guiana, a overseas territory located the Amazonian forest.Due to safety issues and remoteness RHA requested collaboration Armed Forces for epidemiological investigation. A medical unit, six soldiers ensure security mission, were transported by helicopter.During investigation, two episodes...

Worldwide, the socioeconomic impacts of COVID-19 disproportionally affect vulnerable groups in society. This paper assesses responses to, and of, pandemic among mobile migrant populations who work Artisanal Small-scale Gold Mining (ASGM) Suriname French Guiana. These are characterized by poverty, informal or illegal status, limited access to health care information. Field research (November 2020-January 2021) Guiana (January, May, June included qualitative interviews, conversations...

Climate change, population growth, and declining federal budgets are threatening the health of ecosystems, services they provide. Under these changing conditions, managing landscapes resources assumes new unprecedented challenges. Adaptive management has been identified as a natural resource approach that allows practitioners to incorporate change uncertainty into decision-making through an iterative process involves long-term monitoring continued review adjustment actions. However, success...

In the past 10 years, deforestation in Amazon has been annually decreasing, figures 2014 representing less than 20 % of what they were 2004. Does this mean Brazil now controls phenomenon? Answering question is a complex task because unfolds through several dimensions: economic (what are rationales behind deforestation), social (access to land, land conflicts), environmental (impacts on climate, local or global effects, biodiversity) and geopolitical (the role international negotiations...

Les processus d’urbanisation à l’œuvre dans les forêts tropicales sont souvent incompatibles avec le maintien d’agroécosytèmes forestiers diversifiés. Dans régions situées l’écart des fronts pionniers, développement petites villes remet en question la durabilité espaces protégés et agricultures amérindiennes. Ce travail analyse recompositions territoriales agricoles liées l’urbanisation autour de São Gabriel da Cachoeira (Amazonie brésilienne). La ville a connu une croissance rapide durant...

This article aims to understand the relationships between rural–urban mobility and economic differentiation in A mazonian communities, through a multi‐scaled methodological framework. We focus on quilombola communities ( P ará S tate, B razil), we use circulation index untangle concept of system. show that individual patterns are embedded process multilocalisation, articulating rural urban areas at collective level. Economic diversification relies complementarity within households. In this...

During the last 20 years, Amazon region has been at same time a place of massive ecological and social change laboratory experiments aimed promoting sustainable development. Policies project initiatives involving diverse groups environmental contexts have implemented across region. They resulted in mixed outcomes trade-offs between dimensions, making their impact local level difficult to assess successes generalize. The objective DURAMAZ research was provide better understanding these...

The Iratapuru Sustainable Development Reserve is mainly exploited by the community of São Francisco village. To improve their standard living, this village organised its members around a production co‐operative in 1992. Following considerable support from local and international institutions, became symbol sustainable development projects for ‘traditional’ communities Amazon. This was even more so after 2004, when an innovative partnership established between Brazilian cosmetics company...

Com a chegada ao poder de uma força política ultraconservadora, questão dos direitos fundiários povos indígenas do Brasil está colocada novo em questão. Apesar das garantias dadas pela Constituição 1988, o governo Jair Bolsonaro tem fato explicitamente dito que almejava travar toda nova demarcação terra indígena e rever, se for possível, as já foram homologadas. Neste grave quadro, objeto deste artigo é, primeiro lugar, resumir jogo, lembrando da repartição terras no recapitulando os...

Depuis une dizaine d'années, les surfaces déforestées en Amazonie diminuent chaque année et le déboisement 2014 a représenté moins de 20 % celui 2004. Doit-on déduire que Brésil maîtrise désormais phénomène déforestation ? Répondre à cette question implique d'exposer la complexité du déforestation. Celui-ci possède effet nombreuses dimensions : économique (qui défriche, pour gagner quoi ?), sociale (question l'accès terre, conflits fonciers), environnementale (impacts sur climat, effets...

The way vegetation is officially named, classified, and identified has critical implications for ecosystems biodiversity conservation. Yet little attention given to how such issues hinder the efficacy of laws mandating environmental conservation on private land. In Brazilian Amazon where half land now already under tenure or available future land-uses, differences in mapping interpretation directly affect level protection rural properties, especially transition areas forest savanna...

The economic modernization of the Amazon fostered by Brazilian military government during 1960s and 1970s was largely realized without taking into consideration presence local households which lived from extraction forest products (mainly non-timber). When they began to be expulsed, a political resistance, often guided Catholic Church, appeared as well creation unions based on traditional identities, especially that rubber tappers. During 1980s, these made strategic alliance with ecologist...

Natural soundscapes correspond to the acoustical patterns produced by biological and geophysical sound sources at different spatial temporal scales for a given habitat. This pilot study aims characterize temporal-modulation information available humans when perceiving variations in within across natural habitats. is addressed processing from previous [Krause, Gage, Joo.

Soundscapes are increasingly used as innovative entry doors in environmental studies. Facing huge libraries of sound files which cannot be processed manually, acoustic indices provide an overview to the information contained them, well allow for automatic processing. Studies dealing with such have, however, focused more on specific topics or than overall characteristics soundscapes they were analyzing. The aim this paper is propose a holistic approach soundscapes. Our hypothesis that...
