An assessment of the vulnerability of Australia's biodiversity to climate change was commissioned by the Australian Government to help increase our understanding of how to help Australia's rich biodiversity adapt to climate change. The assessment finds that Australia's biodiversity is at risk from even moderate climate change and already under stress, for example from habitat degradation, changed fire regimes and invasive species. Climate change is likely to exacerbate these existing stressors and add additional stresses such as through declining water availability. Australia is one of 17 megadiverse countries - a group of countries that harbour more than 70 per cent of the Earth's species and are therefore considered extremely biodiverse. Australia has many species that are unique to Australia and vulnerable to climate change. About 85 per cent of Australia's terrestrial mammals, 91 of flowering plants, and 90 per cent of reptiles and frogs are found nowhere else in the world. More than 50 per cent of the world's marsupial species occur only in Australia. Rates of extinction of species are likely to increase as the global average temperature rises by just 1.0 or 1.5°C above pre-industrial levels, and likely to accelerate sharply as temperature rises beyond 2 degrees Celsius. The assessment was undertaken by an independent group of experts, led by Professor Will Steffen, for the Natural Resource Management Ministerial Council.

On 25 September, 2015, world leaders met at the United Nations in New York, where they adopted the Sustainable Development Goals. These 17 goals and 169 targets set out an agenda for sustainable development for all nations that embraces economic growth, social inclusion, and environmental protection. Now, the agenda moves from agreeing the goals to implementing and ultimately achieving them. Across the goals, 42 targets focus on means of implementation, and the final goal, Goal 17, is entirely devoted to means of implementation. However, these implementation targets are largely silent about interlinkages and interdependencies among goals. This leaves open the possibility of perverse outcomes and unrealised synergies. We demonstrate that there must be greater attention on interlinkages in three areas: across sectors (e.g., finance, agriculture, energy, and transport), across societal actors (local authorities, government agencies, private sector, and civil society), and between and among low, medium and high income countries. Drawing on a global sustainability science and practice perspective, we provide seven recommendations to improve these interlinkages at both global and national levels, in relation to the UN's categories of means of implementation: finance, technology, capacity building, trade, policy coherence, partnerships, and, finally, data, monitoring and accountability.

Australia's rangeland communities, industries, and environment are under increasing pressures from anthropogenic activities and global changes more broadly. We conducted a horizon scan to identify and prioritise key challenges facing Australian rangelands and their communities, and outline possible avenues to address these challenges, with a particular focus on research priorities. We surveyed participants of the Australian Rangeland Society 20th Biennial Conference, held in Canberra in September 2019, before the conference and in interactive workshops during the conference, in order to identify key challenges, potential solutions, and research priorities. The feedback was broadly grouped into six themes associated with supporting local communities, managing natural capital, climate variability and change, traditional knowledge, governance, and research and development. Each theme had several sub-themes and potential solutions to ensure positive, long-term outcomes for the rangelands. The survey responses made it clear that supporting 'resilient and sustainable rangelands that provide cultural, societal, environmental and economic outcomes simultaneously' is of great value to stakeholders. The synthesis of survey responses combined with expert knowledge highlighted that sustaining local communities in the long term will require that the inherent social, cultural and natural capital of rangelands are managed sustainably, particularly in light of current and projected variability in climate. Establishment of guidelines and approaches to address these challenges will benefit from: (i) an increased recognition of the value and contributions of traditional knowledge and practices; (ii) development of better governance that is guided by and benefits local stakeholders; and (iii) more funding to conduct and implement strong research and development activities, with research focused on addressing critical knowledge gaps as identified by the local stakeholders. This requires strong governance with legislation and policies that work for the rangelands. We provide a framework that indicates the key knowledge gaps and how innovations may be implemented and scaled out, up and deep to achieve the resilience of Australia's rangelands. The same principles could be adapted to address challenges in rangelands on other continents, with similar beneficial outcomes.
