Water at the Core, How COP 30’s Belém Indicators Are Reshaping Climate Adaptation for India and the Global South
Branded the “COP of Implementation,” the 30th Session of the United Nations Climate Change Conference Marked a Decisive Shift—Moving Adaptation from Abstract Promise to Measurable Accountability
Branded the “COP of Implementation,” COP 30, the 30th session of the United Nations Climate Change Conference, held in Belém, Brazil, in November 2025, marked a decisive shift in how adaptation is understood—not as an abstract promise of resilience, but as a measurable, accountable discipline grounded in systems that function under stress. At the centre of this shift is water, moving from the margins of infrastructure planning to the core of climate survival.
For the first time, global adaptation indicators integrated water, sanitation, and hygiene (WASH) into climate accountability, reshaping the water-food-climate nexus with implications for all countries, including India. This was not merely a technical adjustment but a fundamental reorientation of how the international community understands the relationship between climate change and human well-being.
Climate Change Felt Through Water
Climate change is experienced most viscerally through water. Floods submerge cities, droughts hollow out rural economies, glacial melt destabilises Himalayan river systems, saline intrusion contaminates coastal aquifers, and erratic monsoons disrupt food security. Agriculture alone accounts for roughly 40 per cent of anthropogenic methane emissions, with rice cultivation, livestock systems, and organic waste at the centre of the challenge.
Water use efficiency, wastewater reuse, aquifer recharge, and resilient sanitation systems are now climate strategies as much as development priorities. This represents a fundamental shift in perspective. Previously, water infrastructure was viewed primarily through the lens of development—providing services, enabling agriculture, supporting industry. Now, it must also be viewed through the lens of climate resilience—ensuring that systems continue to function when stressed by extreme events.
The 59 Belém Adaptation Indicators, under the UAE Framework for Global Climate Resilience, signal a new discipline in global governance. Two clusters stand out.
The first focuses on climate-resilient water and sanitation systems: reducing climate-induced water scarcity, building resilience to floods and droughts, ensuring universal access to safe drinking water, and upgrading sanitation infrastructure to withstand extreme events. These are not abstract goals but measurable targets that countries must work toward.
The second emphasises risk governance: universal multi-hazard early warning systems by 2027, strengthened hydrometeorological services, and updated national vulnerability assessments by 2030. Water security is no longer about asset creation; it is about whether systems continue to deliver when climate stress intensifies.
India’s Existing Foundations
India is building on existing foundations. The consolidation, in 2019, of water governance under the Ministry of Jal Shakti marked a shift toward integrated stewardship, while the Water Vision 2047 aligns with Belém’s adaptation framework, emphasising sustainability, equity, and resilience.
Groundwater management illustrates this transition. The evolution of the National Aquifer Mapping and Management (NAQUIM) Programme 2.0 has moved from mapping aquifers to implementing aquifer-level management plans—translating hydrological knowledge into policy action. This exemplifies the systems integration that global adaptation indicators now require.
India’s groundwater challenge is immense. The country is the world’s largest user of groundwater, extracting more than China and the United States combined. Aquifers are depleting, quality is deteriorating, and the energy-groundwater nexus creates perverse incentives for over-extraction. NAQUIM 2.0 represents an attempt to move from understanding the problem to solving it—from knowing where the water is to managing how it is used.
River rejuvenation tells a similar story. The National Mission for Clean Ganga (NMCG) has moved beyond sewage treatment to integrate biodiversity, digital monitoring, and international collaboration, making clean rivers a buffer against climatic volatility. The Ganga is not just a river; it is a living symbol of India’s cultural and ecological heritage. Its health is a measure of the nation’s commitment to environmental stewardship.
Three Systemic Risks
Despite visible progress, three systemic risks threaten to slow momentum.
First, water scarcity remains a source of uncertainty. Climate disasters in India are water-related, and WASH systems often serve as the first line of defence. Ensuring rural and urban water supply during floods or prolonged droughts requires climate stress testing of infrastructure, diversification of sources, and redundancy in service delivery—not simply expanding coverage figures.
The distinction between coverage and resilience is crucial. A village may have a piped water supply, but if that supply depends on a single source that dries up during drought or becomes contaminated during floods, coverage figures are misleading. Resilience requires redundancy—multiple sources, backup systems, and the capacity to adapt when primary systems fail.
Second, adaptation finance remains fragile. While global rhetoric speaks of mobilising $1.3 trillion annually by 2035, operational pathways remain uncertain. Without predictable and accessible flows of adaptation finance, post-disaster recovery will crowd out long-term resilience planning. Water projects need explicit classification and funding as climate investments, not mere sectoral costs.
The current financial architecture is ill-suited to adaptation needs. Mitigation projects—renewable energy, energy efficiency, electric vehicles—often generate returns that attract private capital. Adaptation projects—flood protection, drought resilience, water conservation—generate public goods that are harder to monetise. New financial instruments and public funding mechanisms are needed to bridge this gap.
Third, digital fragmentation persists. Despite India’s vast hydrological and meteorological data, artificial intelligence-driven real-time integration into planning, budgeting, and local governance systems remains limited. Data exists but is not accessible; information is available but not actionable.
The potential of digital integration is immense. Real-time data on rainfall, river flows, groundwater levels, and reservoir storage could transform water management. Early warning systems could reach every village. Crop advisories could optimise water use. But realising this potential requires investment in data infrastructure, institutional capacity, and the integration of digital tools into everyday governance.
The Convergence Opportunity
A closer look at India’s institutional landscape reveals that most global adaptation targets already have corresponding domestic missions. Drinking water coverage, sanitation expansion, irrigation efficiency, urban water reforms, and climate action plans exist across Ministries and States. Climate stress indicators must be embedded into mission dashboards.
Belém calls for convergence, not reinvention. The challenge is not to create new programmes but to align existing ones with climate resilience objectives. The Jal Jeevan Mission, which aims to provide piped water to every rural household, can be adapted to ensure that supplies are climate-resilient. The Swachh Bharat Mission can incorporate climate considerations into sanitation planning. The National Adaptation Fund can prioritise water-related projects.
India’s strength in digital public infrastructure offers an opportunity to integrate hydrological data, crop advisories, insurance, and financial flows into interoperable platforms for real-time decision-making. The India Stack—Aadhaar, UPI, DigiLocker—has revolutionised financial inclusion and service delivery. Similar platforms for water and climate data could transform adaptation.
Leading the Global South
The Belém indicators are not a bureaucratic checklist; they are a dashboard for survival. If implemented with seriousness, they can transform adaptation from a peripheral conversation into the organising principle of development strategy. India stands at a pivotal moment. Its domestic water reforms, technological capabilities, and community-led initiatives position it not just as a participant in global climate negotiations but also as a potential leader in operationalising adaptation at scale.
The Global South looks to India for example. Countries facing similar challenges—water scarcity, climate vulnerability, rapid urbanisation—need models that work. India’s experience with water governance, from the revival of traditional water harvesting structures to the deployment of satellite-based monitoring, offers lessons that can be adapted elsewhere.
Water must anchor climate action. Implementation must be swift, equitable, and technologically robust. Resilience should be measured not by infrastructure built, but by systems that continue to serve people when the next flood arrives, when the next drought lingers, and when the next climate shock tests the nation’s preparedness.
India has much of the blueprint in place. The task now is to align missions, metrics, and money quickly enough to convert ambition into measurable resilience—and in doing so, lead the Global South by exemplary performance.
Q&A: Unpacking COP 30’s Belém Indicators and India’s Water Future
Q1: What was significant about COP 30 in Belém, Brazil?
A: COP 30 was branded the “COP of Implementation,” marking a decisive shift from abstract promises of resilience to measurable, accountable adaptation. For the first time, global adaptation indicators integrated water, sanitation, and hygiene (WASH) into climate accountability. The 59 Belém Adaptation Indicators, under the UAE Framework for Global Climate Resilience, establish measurable targets for climate-resilient water systems, universal access to safe drinking water, and upgraded sanitation infrastructure that can withstand extreme events.
Q2: Why is water central to climate adaptation?
A: Climate change is experienced most viscerally through water—floods submerge cities, droughts hollow out rural economies, glacial melt destabilises river systems, saline intrusion contaminates aquifers, and erratic monsoons disrupt food security. Water use efficiency, wastewater reuse, aquifer recharge, and resilient sanitation systems are now climate strategies as much as development priorities. The question is no longer whether infrastructure exists, but whether systems continue to deliver when climate stress intensifies.
Q3: What existing foundations does India have for meeting the Belém indicators?
A: India has several foundations: the consolidation of water governance under the Ministry of Jal Shakti (2019); the Water Vision 2047 emphasising sustainability and resilience; NAQUIM 2.0 moving from aquifer mapping to aquifer-level management; the National Mission for Clean Ganga integrating biodiversity and digital monitoring; and missions like Jal Jeevan and Swachh Bharat that can incorporate climate considerations. The challenge is convergence—aligning existing programmes with climate resilience objectives.
Q4: What are the three systemic risks threatening progress?
A: First, water scarcity remains uncertain—ensuring supply during floods or droughts requires climate stress testing, source diversification, and redundancy, not just coverage expansion. Second, adaptation finance is fragile—without predictable flows, post-disaster recovery crowds out long-term planning; water projects need explicit classification as climate investments. Third, digital fragmentation persists—despite vast data, AI-driven real-time integration into planning and governance remains limited.
Q5: What opportunity does India have to lead the Global South?
A: India’s domestic water reforms, technological capabilities (including digital public infrastructure), and community-led initiatives position it as a potential leader in operationalising adaptation at scale. The Global South faces similar challenges—water scarcity, climate vulnerability, rapid urbanisation—and needs working models. By aligning missions, metrics, and money to convert ambition into measurable resilience, India can set an example for other nations. Resilience should be measured not by infrastructure built, but by systems that continue to serve when the next climate shock arrives.
