PRONEA- Progeama Nacional de Educação Ambiental

Journal Articles & Books
Maio, 2014
Brasil

A Educação Ambiental surge como política pública no
Brasil com o estabelecimento da Política Nacional
de Meio Ambiente – PNMA (Lei nº 6.938, de 1981),
no contexto da Conferência Intergovernamental de Educação Ambiental de Tbilisi (1977), que destacou o processo educativo como dinâmico, integrativo, permanente e transformador, justamente porque possibilita a aquisição de conhecimentos e habilidades de forma participativa. Desde então, outros marcos legais foram estabelecidos.

Estatuto da Agricultura Familiar Portuguesa

Outubro, 2014
Portugal

É cada vez mais forte a percepção das populações, de governos e de instituições internacionais de que a humanidade não pode continuar a ser empurrada para o precipício, com as políticas das últimas décadas, de intensificação da produção agropecuária e florestal e o aumento do poder hegemónico de grandes companhias multinacionais da indústria e da distribuição, que controlam a produção e detêm cada vez mais terra, provocando o esgotamento de recursos naturais, acidentes climáticos, pragas e doenças, desertificação de muitas regiões, fome e subnutrição, esvaziamento e asfixia de economias loc

Climatic stress and anthropogenic disturbances have caused significant environmental changes in the Sahel. In this context, the importance of soil is often underrepresented. Thus, we analyze and discuss the interdependency of soil and vegetation by classifying soil types and its woody cover for a region in the Senegalese Ferlo. Clustering of 28 soil parameters led to four soil types which correspond with local Wolof denotations: Dek, Bowel, Dior and Bardial.

Smallholders, Agrarian Reform, and Globalization in the Brazilian Amazon: Cattle versus the Environment

Peer-reviewed publication
Setembro, 2016

Smallholder farming in the Brazilian Amazon has changed markedly over the last few decades, following a pervasive swing to cattle production observed across the basin. These changes have brought opportunities for accumulating a modicum of wealth that were not available in the early stages of colonization. At the same time, they have reconfigured livelihood systems away from diversified agriculture to a strong engagement with the cattle economy.

Historical Changes of Land Tenure and Land Use Rights in a Local Community: A Case Study in Lao PDR

Journal Articles & Books
Dezembro, 2016
Laos

Land-titling programs, land and forest allocation programs, and projects on state-allocated land for development and investment in Laos have been key drivers of change in land tenure. These have triggered major shifts in land use rights, from customary, to temporary, and then to permanent land use rights. This article explores how government programs to grant land use rights to individual households have affected the way people have been able to acquire and secure land tenure.

Toward the Integrated Framework Analysis of Linkages among Agrobiodiversity, Livelihood Diversification, Ecological Systems, and Sustainability amid Global Change

Peer-reviewed publication
Junho, 2016

Scientific and policy interest in the biological diversity of agriculture (agrobiodiversity) is expanding amid global socioeconomic and environmental changes and sustainability interests. The majority of global agrobiodiversity is produced in smallholder food-growing.

Impacts of Logging Road Networks on Dung Beetles and Small Mammals in a Malaysian Production Forest: Implications for Biodiversity Safeguards

Peer-reviewed publication
Setembro, 2014

Various international bodies and non-governmental organizations (NGOs) have proposed guidelines for safeguarding biodiversity. Nevertheless, quantitative criteria for safeguarding biodiversity should first be established to measure the attainment of biodiversity conservation if biodiversity is to be safeguarded effectively. We conducted research on the impact of logging on biodiversity of dung beetles and small mammals in a production forest in Temengor Forest Reserve, Perak, Malaysia.

Greenhouse Gas Implications of Peri-Urban Land Use Change in a Developed City under Four Future Climate Scenarios

Peer-reviewed publication
Dezembro, 2016

Present decisions about urbanization of peri-urban (PU) areas may contribute to the capacity of cities to mitigate future climate change. Comprehensive mitigative responses to PU development should require integration of urban form and food production to realise potential trade-offs. Despite this, few studies examine greenhouse gas (GHG) implications of future urban development combined with impacts on PU food production.
