Não dá para mudar o tom da prosa. A visita de Temer à Noruega, o pito que ganhamos do país que sediou, de 1984 a 1987, a primeira Comissão Mundial sobre Meio Ambiente e Desenvolvimento, da qual resultou o famoso Relatório Brundtland, ou “Nosso Futuro Comum”. “Vocês estão desmatando demais”, disse a primeira-ministra Erna Solberg a Temer na sexta-feira (23). Foi vaga, sem conteúdo, a resposta do nosso ministro do meio ambiente, José Sarney Filho.
The Amazon basin faces irreversible environmental disturbance on an enormous scale due to hydroelectric dam development. Hundreds of existing and planned dams in both the Amazonian lowlands and the Andean headwaters are already impacting, and will continue affecting, waterways, floodplains and the estuary by disrupting sediment and nutrient flows.
This is the message of a new study, published in Nature, which quantified the impacts of dams on the hydrology and geography of each of the Amazon’s 19 major sub-basins.
Religious and indigenous leaders appealed on Monday for better protection of tropical forests from the Amazon to the Congo basin, with a Vatican bishop likening current losses to a collective suicide by humanity.
Christian, Muslim, Jewish, Hindu, Buddhist and Daoist representatives met indigenous peoples in Oslo to explore moral and ethical arguments to shield forests that are under threat from logging and land clearance for farms.

Would forced migration end, if people knew that they could survive and thrive in their homeland?
The Extinction and Livestock international conference will examine how we can
transform our global food and farming systems to work for people, the planet
and animals. It will bring together diverse interests – conservation &
livestock production, land & water use, the environment & climate change,
ethics & economics, healthy & sustainable diets, food security, food
business– and act as a catalyst for future collaboration and solution
A one year field trial was carried out on three adjacent unfertilised plots; an 18 year old grassland, a 14 year old established Miscanthus crop, and a 7 month old newly planted Miscanthus crop. Measurements of N2O, soil temperature, water filled pore space (WFPS), and inorganic nitrogen concentrations, were made every one to two weeks. Soil temperature, WFPS and NO3− and NH4+ concentrations were all found to be significantly affected by land use.
In order to address the challenges in coastal regions, there is the need to understand the extent and impacts of past changes and their implications for future management. Land use data and remotely-sensed imagery are often used to provide insights into these changes. Often, however, existing land use data are inconsistent, thus differences observed through their analyses could also be attributable to error. The use of multiple layers of data, in addition and as related to basic land use layers, has been suggested in the literature as a method to mitigate such error.
Some authorities argue that land is the most fundamental of natural resources. If their arguments fail to convince, we certainly have to cede that land is a limited natural resource. Aside from a few thousand Moken living on the Andaman Sea, humans are tied to the land. Most of us live, eat and sleep on land, even oil rig workers in the Gulf of Mexico, Filipino merchant seamen, Japanese fishermen and British naval ratings divide their lives between sea and land.
Estimating deforested areas and deforestation rates have become key steps for quantifying environmental services of tropical rain forests, particularly as linked to programs such as Reduced Emissions from Deforestation and Forest Degradation (REDD). In Southeastern Peru, reliable estimates of land-cover change (LCC) are important for monitoring changes in the landscape due to agricultural expansion, pasture creation and other socio-economic influences triggered by the Inter-Oceanic Highway (IOH).
Fire is a key component of many land use systems and a determinant of land change. There is a growing concern that climate change will cause more catastrophic fires, but in many areas the impacts will be mediated by human land use practices. In African savannas, for example, fires are frequent and research finds low inter-annual variability in burned areas in places with highly variable rainfall. This regularity of fire suggests that African regimes are humanized, meaning that they are governed by human practices more than climate variation.
