TL;DR: A comprehensive assessment of the world’s rivers and their connectivity shows that only 37 per cent of rivers longer than 1,000 kilometres remain free-flowing over their entire length.
Abstract: Free-flowing rivers (FFRs) support diverse, complex and dynamic ecosystems globally, providing important societal and economic services. Infrastructure development threatens the ecosystem processes, biodiversity and services that these rivers support. Here we assess the connectivity status of 12 million kilometres of rivers globally and identify those that remain free-flowing in their entire length. Only 37 per cent of rivers longer than 1,000 kilometres remain free-flowing over their entire length and 23 per cent flow uninterrupted to the ocean. Very long FFRs are largely restricted to remote regions of the Arctic and of the Amazon and Congo basins. In densely populated areas only few very long rivers remain free-flowing, such as the Irrawaddy and Salween. Dams and reservoirs and their up- and downstream propagation of fragmentation and flow regulation are the leading contributors to the loss of river connectivity. By applying a new method to quantify riverine connectivity and map FFRs, we provide a foundation for concerted global and national strategies to maintain or restore them. A comprehensive assessment of the world’s rivers and their connectivity shows that only 37 per cent of rivers longer than 1,000 kilometres remain free-flowing over their entire length.

TL;DR: In this article, the authors present the results of the first explicitly marine-focused, global assessment of protected areas in relation to global marine protection targets, and validate concerns over the relevance and utility of broad conservation targets.
Abstract: Current global marine protection targets aim to protect 1030% of marine habitats within the next 3 - -5 years. However, these targets were adopted without prior assessment of their achievability. Moreover, ability to moni- tor progress towards such targets has been constrained by a lack of robust data on marine protected areas. Here we present the results of the first explicitly marine-focused, global assessment of protected areas in relation to global marine protection targets. Approximately 2.35 million km 2 , 0.65% of the world's oceans and 1.6% of the total marine area within Exclusive Economic Zones, are currently pro- tected. Only 0.08% of the world's oceans, and 0.2% of the total marine area under national jurisdiction is no-take. The global distribution of protected areas is both uneven and unrepresentative at multiple scales, and only half of the world's marine protected areas are part of a coherent network. Since 1984 the spatial extent of marine area pro- tected globally has grown at an annual rate of 4.6%, at which even the most modest target is unlikely to be met for at least several decades rather than within the coming decade. These results validate concerns over the relevance and utility of broad conservation targets. However, given the low level of protection for marine ecosystems, a more immediate global concern is the need for a rapid increase in marine protected area coverage. In this case, the process of comparing targets to their expected achievement dates may help to mobilize support for the policy shifts and increased resources needed to improve the current level of marine protection.

TL;DR: In this article, the authors investigated the cumulative human impacts in the marine environment and found that commercial fishing, land-based activities and marine transportation accounted for 57.0%, 19.1%, and 17.7% of total cumulative impacts, respectively.

TL;DR: In this article, a hybrid approach to climate-adaptive conservation landscape planning for snow leopards in the Himalayan Mountains was developed. But, the authors did not consider the impact of climate change on the distribution of snow leopard habitat and linkages.
