Indonesia in 2035: Climate risks to security in the Indo-Pacific

The Indo-Pacific region is particularly exposed to climate impacts, and Indonesia, like many countries, will be severely affected by climate impacts in the decade to come. The effects of climate-amplified disasters, combined with the political, social and economic consequences of climate impacts originating from within and across the region, will strain Indonesia’s economic and national-security interests.

This report presents the findings of a narrative-driven scenario to stress-test Indonesia’s climate risks emerging by 2035. Its objective is to identify opportunities for Indonesia and its economic and strategic partners to prepare for and mitigate the risks.

While Australian policymakers have devoted significant attention to the existential risks that Pacific island countries face, Southeast Asian countries are also highly exposed and often face similar risks. Within Southeast Asia, Indonesia’s climate risks have received very limited attention despite its high exposure to climate hazards, its very large population (over 10 times larger than all Pacific island countries combined) which is densely concentrated in vulnerable coastal areas and small islands, and its history of political unrest associated with disruptions to food and energy security. It’s also one of the closest neighbouring countries to Australia. Figure 1 on page 5 provides a visual summary of the interacting hazards, risks and consequences highlighted in this report.

The population size of Southeast Asian countries and their often-close proximity to one another means that climate impacts in one country will often have consequences beyond their borders and for their neighbours across the region. Gaining a better understanding of how Indonesia, as the largest country in Southeast Asia, will be affected by climate developments is vital, given both the domestic and regional consequences.

Even below the ‘safe’ threshold of a 1.5°C rise in global average temperature—the aspirational target set in 2015 by the signatories to the Paris Agreement—countries around the world are already experiencing serious, record-setting, climate-driven disruptions on a large scale. The era of climate-induced disruption is clearly already upon us—and it will intensify rapidly.

Building resilience while preparing for future disruption requires an enhanced appreciation of climate risk that goes beyond adapting to more frequent and severe natural hazards, such as floods and fires.

Development-assistance and defence communities have embraced the importance of treating climate change as a threat to human, economic and traditional military security. The challenge is to build the capacity and tools to assess the broad suite of security-related risks of climate change—and to translate that information into measures to mitigate the risks. Understanding the complexity and uncertainty associated with climate trends is a daunting task, greatly complicated by the need to incorporate the many ways climate change affects social, political and economic systems.

The scenario developed in this report isn’t a prediction of the future, but rather a description of a possible future. It identifies many climate impacts, but suggests three primary pathways through which Indonesia may face compounding and destabilising climate disruptions:

  • Significant food insecurity from losses to domestic production due to shifting precipitation timing and extremes across the wet and dry seasons, heightened sensitivity to shocks in global food prices, and reduced government ability to absorb economic shocks, such as food-price hikes.
  • Large-scale coastal population displacement driven by Indonesia’s high coastal population density and the significant exposure of that population to sea-level rise and climate-induced coastal flooding.
  • Slowed economic growth from lost agricultural output, declining revenues from stranded fossil-fuel assets, rising disaster costs at home and abroad affecting economic infrastructure and supply chains, and rising challenges in responding to domestic crises driven by food insecurity and population displacements.

A major finding of this research is that, in little more than a decade, Indonesia is likely to experience major climate disruptions that also amplify climate and security risks in the region, resulting in a range of additional and cascading risks for Australia. A second overarching finding in the report is that Indonesia may be underestimating the likely scale of the climate risks and should devote greater attention to analysing them. It’s in Australia’s interests to do the same and, as a good neighbour, to coordinate an Australian whole-of-government effort to support Indonesia to mitigate the risks, including cross-border risks.

Stop the World: Climate change and security with ‘Climate General’ Tom Middendorp

In this episode of Stop the World, Justin Bassi speaks to retired General Tom Middendorp – also known as the ‘Climate General’ – about the links between climate change, defence and security. They discuss the impact of climate change on the military and its role in disaster preparedness and response.

With a growing global population meaning a growing demand on natural resources, the conversation also explores how we can adapt and learn to do more with fewer resources. They consider the role that technology and innovation can play in responding to climate change, as well as the importance of supply chain security.

They also discuss the different climate risks in South and Southeast Asia and the Pacific, and how countries like Australia and the Netherlands can work together to support these regions and help address the combined climate and security threats we face.

The geopolitics of water: How the Brahmaputra River could shape India–China security competition

This report assesses the geopolitical impact of a possible dam at the Great Bend of the Brahmaputra. In particular, it exams the dam as a potential source of coercive leverage China may gain over India. A dam there would create four likely strategic effects: it would very likely consolidate Beijing’s political control over its distant borderlands; it would create the potential for massive flooding as a tool of violence; it may affect human settlement and economic patterns on the Indian side of the border, downstream; and it would give Beijing water and data that it could withhold from India as bargaining leverage in unrelated negotiations.

To mitigate those challenges and risks, the report provides three policy recommendations for the Indian Government and its partners in Australia and the US. First, it recommends the establishment of an open-source, publicly available data repository, based on satellite sensing, to disseminate information about the physical impacts of the Great Bend Dam. Second, it recommends that like-minded governments use international legal arguments to pressure Beijing to abide by global norms and conventions. Third, it recommends that the Quad—the informal group comprising Australia, India, Japan and the US—use its humanitarian assistance and disaster relief (HADR) guidelines to begin to share information and build capacity for dam-related contingencies.

National resilience: lessons for Australian policy from international experience

The strategic circumstances that Australia contemplates over the coming decades present multiple, cascading and concurrent crises. Ensuring a safe and secure Australia, able to withstand the inevitable shocks that we’ll face into the future, will require a more comprehensive approach to strategy than we’ve adopted over the past seven decades. We can’t rely on the sureties of the past. The institutions, policies and architectures that have supported the nation to manage such crises in our history are no longer fit for purpose.

The report highlights lessons drawn from international responses to crisis, to assist policymakers build better responses to the interdependent and hyperconnected challenges that nations face. The report brings together the disciplines of disaster management, defence strategy and national security to examine what an integrated national approach to resilience looks like, and how national resilience thinking can help Australia build more effective and more efficient responses to crisis and change.

The report concludes that now is the time to commence action to deliver a national resilience framework for Australia. Collective, collaborative action, enabled by governments, built on the capability and capacity of Australian industry and the community, and aimed at the goal of a resilient Australia, can ensure that we’re well placed to face the future with confidence.

China, climate and conflict in the Indo-Pacific

This paper surveys the current reporting and analysis on climate and security to explore the implications that climate change may have for China’s ability to prosecute its security goals in the region’s three major hotspots: the SCS, Taiwan and the India–China border conflict. Those three hotspots all involve longstanding border and territorial disputes between China and other nations and may draw in various levels of US involvement should China continue to escalate tensions.

China, climate change and the energy transition

This report surveys China’s enormous energy transition to renewables. It begins by sketching the energy challenges China faces and its climate-change-related energy policies, in the context of the global geopolitics of the energy transformation. Next the report focuses on conventional energy sources (oil and natural gas), followed by electricity, and energy technologies. Although the report is intended primarily to survey developments to date, it concludes with some brief observations about the considerable energy challenges China faces in the years ahead.
