A musical protest at the Rio carnival will stress the damaging impacts of factory farming on indigenous people and on global warming.

Sub-Saharan Africa has one of the least developed policy environments to support energy access, says a new World Bank report released on Wednesday.

A subset of Sustainable Development Goals pertains to improving people's living standards at home. These include the provision of access to electricity, clean cooking energy, improved water and sanitation. We examine historical progress in energy access in relation to other living standards. We assess regional patterns in the pace of progress and relative priority accorded to these different services. Countries in sub-Saharan Africa would have to undergo unprecedented rates of improvement in energy access in order to achieve the goal of universal electrification by 2030.

We mapped the inferred long-distance migrations of four species of Amazonian goliath catfishes (Brachyplatystoma rousseauxii, B. platynemum, B. juruense and B. vaillantii) based on the presence of individuals with mature gonads and conducted statistical analysis of the expected long-distance downstream migrations of their larvae and juveniles.

It’s estimated that about 10 per cent of global emissions comes from deforestation — meaning we could make considerable progress toward halting climate change simply by keeping what remains of the

This document looks at how social protection can be a tool to manage climate risk, with examples from Brazil, Kenya and Lesotho. It discusses how social protection can help bridge the gap between humanitarian and development aid as well as absorb and adapt to climate shocks.

Mosquito-borne viruses threaten public health worldwide. When the ratio of competent vectors to susceptible humans is low enough, the virus’s basic reproductive number (R0) falls below 1.0 (each case generating, on average, <1.0 additional case) and the infection fades out from the population. Conventional mosquito control tactics, however, seldom yield R0 < 1.0.

Ongoing deforestation is a pressing, global environmental issue with direct impacts on climate change, carbon emissions, and biodiversity. There is an intuitive link between economic development and overexploitation of natural resources including forests, but this relationship has proven difficult to establish empirically due to both inadequate data and convoluting geo-climactic factors. In this analysis, we use satellite data on forest cover along national borders in order to study the determinants of deforestation differences across countries.

To reduce greenhouse gas emissions in the coming decades, many governments will have to reform their energy policies. These policies are difficult to measure with any precision. As a result, it is unclear whether progress has been made towards important energy policy reforms, such as reducing fossil fuel subsidies. We use new data to measure net taxes and subsidies for gasoline in almost all countries at the monthly level and find evidence of both progress and backsliding. From 2003 to 2015, gasoline taxes rose in 83 states but fell in 46 states.

A new study published in the journal Nature Ecology and Evolution, locates hotspots of threats to wildlife and describes how they are related to consumers' demand in other parts of the world.

Identifying hotspots of species threat has been a successful approach for setting conservation priorities. One important challenge in conservation is that, in many hotspots, export industries continue to drive overexploitation.
