A challenge becomes an opportunity when it is bigger than any one country — because then working together stops being a kindness and becomes the only method that works. Yes, the chapter gives several clear examples.
1. The 2004 tsunami → an ocean-wide warning system
On 26 December 2004 an earthquake under the Indian Ocean near Indonesia triggered a tsunami. In India alone “some 15,000 people lost their lives, especially in Tamil Nadu, Kerala, and the Andaman and Nicobar Islands”; across the whole region “more than 200,000 people were killed”. The chapter says plainly what followed: “This disaster exposed the urgent need for better early warning systems. India thus joined hands with Indonesia, Sri Lanka, Thailand and other Indian Ocean countries to set up a network of sensors, satellites, and communication links.” The Indian Tsunami Early Warning Centre in Hyderabad now alerts neighbouring countries too.
2. Rising seas → shared work on climate and solar energy
The Maldives faces a sea-level rise that “could reach 1 metre by the end of the century, partly submerging many of its islands”; in 2009 its president and cabinet held a meeting 4 m underwater to draw attention to the danger. Bangladesh faces rising seas and more intense cyclones, with many people likely to lose homes or livelihoods. The response has been cooperative: the Maldives is a member of the International Solar Alliance, an Indian initiative, “another example of the long-term relationship between the two countries”.
3. A shared forest → joint protection
The Sundarban National Park, a UNESCO World Heritage Site, has “its protection and management coordinated by the two neighbours”, India and Bangladesh. About two-thirds of the forest lies in Bangladesh and the rest in India. It shelters the Bengal tiger, matters for biodiversity, and “serves as a barrier to cyclones” — so protecting it protects both countries.
4. Seas that must be kept safe → maritime security partnerships
India and Indonesia have “shared concerns about piracy, climate change, and the protection of sea lanes, which makes their partnership especially important”. India and Malaysia work “closely on regional security and maritime stability”. Oman is India's closest defence partner in the Gulf and the first country in the region where India holds joint exercises with all three armed forces; the two “work together on Indian Ocean maritime security”.
Why shared challenges work this way: a wave, a cyclone, a rising sea and a pirate ship all ignore borders. One country's warning centre, however good, cannot save a coast it does not watch. So the cheapest and safest answer is to pool sensors, ships and information — and having pooled them, the countries find they trust each other a little more than before.
