ON Monday, world leaders will gather at the UN in New York for the Climate Action Summit.

Their goal is simple – to increase ambition and accelerate action in the face of a mounting climate emergency.

For many this means ambition and action that enables countries to decarbonise their economies by the middle of the century.

But that is only half the equation.

Equally ambitious plans are also needed to build the resilience of vulnerable sectors and communities being battered by climate-related disasters of increasing frequency, intensity and unpredictability.

Nowhere is this reality starker than in the Asia-Pacific region, which has suffered another punishing year of devastation due to extreme events linked to climate change.

Last year, Kerala state in India had its worst floods in a century.

The floods in Iran in April this year were unprecedented.

Floods and heatwaves in quick succession in Japan caused widespread destruction and loss of life.

In several South Asian countries, immediately following a period of drought, weeks of heavy monsoon rains this month unleashed floods and landslides.

Across Northeast and South Asia, record high temperatures have been set.

The latest research from the UN Economic and Social Commission for Asia and the Pacific (Unescap) has shown that intense heatwaves and drought are becoming more frequent, unusual tropical cyclones originate from beyond the traditional risk zones and follow tracks that have not been seen before, and unprecedented floods are occurring throughout the region.

The science tells us that the impacts are only going to increase in severity and frequency as greenhouse gas emission concentrations in the atmosphere continue to rise.

The poor and vulnerable are taking the biggest hit.

Disasters cost lives and damage livelihood and assets.

Increases in disaster exposure are increasing child malnutrition and mortality and forcing poor families to take children out of school, entrenching inter-generational poverty.

And they perpetuate inequalities within and between countries.

In Southeast Asia, Cambodia, Laos and Vietnam have all faced losses of more than five per cent of their GDP.

A person in the Pacific small island developing states is three to five times more at risk of disasters than a person elsewhere in our disaster-prone region.

Vanuatu has faced annual losses of more than 20 per cent of its GDP.

In short, disasters are slowing down and often reversing poverty reduction and widening inequality.

But amid this cycle of disaster and vulnerability lies a golden opportunity for careful and forward-looking investment.

The Global Commission on Adaptation recently found that there would be more than $7 trillion in total net benefits between now and 2030 from investing in early warning systems, climate-resilient infrastructure, improved dryland agriculture, mangrove protection and in making water resources more resilient.

So where could countries in the Asia-Pacific region make a start?

First, by providing people with the means to overcome shocks.

Increasing social protection is a good start. Currently developing countries in Asia and the Pacific only spend around 3.7 per cent of GDP on social protection, compared to the world average of 11.2 per cent, leaving people vulnerable if they get sick, lose their jobs, become old or are hit by a disaster.

In the aftermath of Typhoon Haiyan in the Philippines, we saw the effectiveness of social protection, especially cash transfers, but these were only possible because the government could use the conditional cash transfer system and mechanisms already in place for poor and vulnerable people.

Second, by lifting the financial burden off the poor.

Disaster risk finance and insurance can cover poor and vulnerable people from climate shocks and help them recover from disaster, such as Mongolia’s index-based insurance scheme to deal with the increasing frequency of dzuds, where a combination of droughts and a shortage of pasture leads to massive livestock deaths.

Disaster risk finance can also help countries pool the risks, as is happening through the emerging Asean Disaster Risk Financing and Insurance programme.

Third, by increasing investment in new technologies and big data.

Artificial Intelligence-driven risk analytics as well as a fast combination of sensor and geospatial data can strengthen early warning systems.

Big data, including from mobile phones, can help identify and locate vulnerable populations in risk hotspots who have been the hardest to reach so far, ensuring faster, more targeted help after disasters.

Experience around the region has already shown the potential.

In India, a combination of automated risk analytics, geospatial data and the digital identity system (the so-called AADHARR system) have helped to identify and deliver assistance to millions of drought-affected subsistence farmers.

But much more investment is needed to make technology an integral part of disaster risk response and resilience building.

Climate related disasters are likely to increase in the Asia-Pacific region.

This is our new climate reality.

This UN summit provides the perfect platform to make the commitments needed for helping communities and people adapt to this reality before decades of hard-won development gains are washed away.
