Surface distribution data from monitoring stations in the eastern South China Sea that were occupied during four cruises between spring 1994 and summer 1998 dis…
The June 1991 eruption of Mount Pinatubo, Philippines, was the second largest of the 20th century, emplacing 5--6 km 3 of pyroclastic-flow material and creating record high sediment yields on rivers draining the volcano. This thesis explores landscape response to and recovery from sediment loading in the 1991 eruption from the drainage basin scale to mo…
We determined vegetation structure and environmental variables in the Pasig-Potrero and Sacobia River systems on the east flank of Mount Pina-tubo, Luzon, Philippines, to define growth form and taxonomic groups that have influenced primary succession during the 15 yr since the eruption. We selected eight sites within an east-west range of 11.5 km, a nor…
Studying recovering plant biodiversity on Mount Pinatubo may provide valuable insights that improve our understanding of recovery of other ecosystems following disturbances of all types. Ongoing sheet and rill erosion coupled with mass waste events in the unstable pyroclastic flow deposits persist, effectively re-setting primary succession at micro-land…
The U.S. Agency for International Development (USAID) contracted with the U.S. Army Corps of Engineers (USACE) for the preparation of a comprehensive Recovery Action Plan (RAP). The RAP evaluates methods for controlling the sedimentation within eight river basins and the higher risk of flooding due to sediment-clogged drainage channels resulting from th…
This infographic shows the overview of the Australian Government's efforts including impacts, funding and action, to support the recovery of its native wildlife and their habitats from the devastating Black Summer bushfires of 2019-20.
The Middle East & North Africa Climate Roadmap will bring climate and development together by adopting an economy-wide, whole of government approach to strengthen institutions, overcome barriers to private sector engagement, foster regional integration – while ensuring that no one is left behind. Countries in the Middle…
This study aimed to explore challenges for nature-based solutions (NbS) governance by analyzing the development and implementation of NbS in Asia. NbS consist of a range of measures that address various societal challenges, including climate change, natural disasters, and water security, by combining human well-being and biodiversity benefits. Although…
The purpose of this document is to highlight design considerations for conducting post-fire reconnaissance surveys to assess fire severity, habitat condition and threats, as well as the status of priority threatened species and ecological communities listed by the federal Government as most vulnerable to the 2019-20 wildfires. The document consists of f…
Fire occurs naturally in many ecosystems and is predicted to increase in frequency and severity with climate change. The 2019–2020 Australian bushfire season was extreme, unprecedented in scale and severity, burning almost 19 million ha. This included half of the Gondwanan rainforests in eastern Australia, an ecosystem with no documented record of fire.…
The recent bushfires in Australia have attracted worldwide attention. With over 12m hectares burnt so far – roughly the size of England – the bushfires are truly a disaster of global proportions. There has been tragic loss of human lives, people severely injured, livestock killed, homes, buildings and infrastructure destroyed, while the impacts on fores…
Australia’s 2019–2020 ‘Black Summer’ bushfires burnt more than 8 million hectares of vegetation across the south-east of the continent, an event unprecedented in the last 200 years. Here we report the impacts of these fires on vascular plant species and communities. Using a map of the fires generated from remotely sensed hotspot data we show that, acros…
The catastrophic eruption of Mt. Pinatubo in 1991 destroyed the forests that covered the peak and impacted the surrounding habitat over a broad area of central Luzon. Information on the mammal fauna of Mt. Pinatubo prior to the eruption is limited but documents a variety of native mammals. In 2011 and 2012, we surveyed mammals at localities along an ele…
Australia’s unprecedented 2019 – 2020 bushfire season devastated the nation. Across the country, approximately 47 million acres were burned, with 31 million acres primarily in forest and bushland habitats. Tragically, 34 lives were lost and close to 2,700 homes were destroyed.
In January we estimated that 1.25 billion animals may have been killed by th…
The State of Finance for Nature in the G20 report attempts to capture the complete amount and future need for G20 country spending on nature-based solutions assets and activities. It reveals that current G20 investments in nature-based solutions are insufficient, at USD 120 billion/year, and G20 Official Development Assistance and private sect…
