Across India, new highways, logistics corridors, industrial parks, energy projects, and digital platforms are changing how people live and how businesses operate. This investment is occurring at enormous scale. India's annual public capital expenditure has increased from US$53 billion in 2021 to more than US$133 billion in 2026, making infrastructure one of the country's principal engines of economic growth.

This investment push sits at the heart of India's Viksit Bharat @2047 ambition: creating the foundations for a developed economy by the centenary of independence. The scale of the challenge is equally significant. India's urban population is projected to approach 900 million by 2047, up from roughly 500 million today, creating unprecedented demand for transport, water, energy, housing, and municipal services.

Yet the scale of construction can obscure a harder question: will the systems we build today continue to work when the conditions around them change?

Everywhere, we see the operating environment becoming less predictable with intensifying climate pressures, expanding cities, and rapidly evolving technologies, industries, markets and supply chains. Infrastructure designed around one set of assumptions is likely to be required to operate under very different conditions a decade from now.

For much of the past century, infrastructure planning concentrated principally on capacity. Governments needed more roads, power generation, water systems, ports, railways, and public services to support growing populations and economies. That need has not disappeared, and India still requires substantial investment.

We know that when we are building for resilience we must think beyond capacity. A transport network is more than its roads and vehicles as it also depends on the institutions that operate it, the information used to manage demand, the financing available for maintenance, and the people and businesses that rely on it. Water infrastructure must do more than deliver a fixed volume under historical rainfall patterns and energy networks must meet rising demand while accommodating new sources of generation and changing patterns of consumption.

The long-term value of physical assets increasingly depends on the strength of the systems around them, and this principle is visible beyond conventional infrastructure.

Resilience is Built through Systems

In our work in Odisha, we have programmes supporting smallholder farmers that have combined improvements in production and post-harvest practices with stronger market connections, quality standards, and better access to information about buyer demand. The value does not come from one intervention alone. It comes from giving farmers more ways to respond. When demand shifts, they can adjust what they produce and when market conditions change, they are better equipped to identify alternatives.

That is what an adaptive system does – it creates options rather than dependence on a single solution. The reality is that resilience emerges when people have access to information, institutions, relationships, and capabilities that allow them to respond to changing conditions. The same principle applies at larger scales.

India's digital public infrastructure provides one of the clearest examples. Built to service a population of more than 1.4 billion people, it connects digital identity, payments, and data exchange through interoperable public platforms.

Its significance lies not only in the number of people it serves, but also in its ability to evolve. New services, users, and applications can be added without rebuilding the underlying foundation.

Well-designed infrastructure should not become less relevant as its operating environment changes. It should become more capable.

Financing the Ability to Adapt

Infrastructure finance offers another perspective on the same principle. We have contributed to efforts to develop innovative financing mechanisms, including India's first green municipal bond for urban transport. These weren’t simply about raising capital for a single project, rather they helped establish a financing approach that cities can use to fund, maintain, and improve infrastructure over the long term.

Here again, the value lies in the system as much as the asset. Financing capability, institutional capacity, and governance arrangements often determine whether infrastructure remains effective decades after construction is complete.

To respond successfully, we must strengthen the underlying systems. India's investments in manufacturing, renewable energy, logistics, skills development, entrepreneurship, and strategic sectors reflect a broader effort to build resilience alongside economic growth. We cannot isolate the economy from change but it is possible to improve its ability to respond to change.

Ownership Determines What Endures

This brings us to perhaps the most important system of all: ownership. One of the most consequential lessons from development is that long-term sustainability rarely comes from external support alone.

Systems endure when people have a stake in them and the most durable programmes position communities as participants and owners rather than beneficiaries. When people own outcomes, knowledge remains local, institutions continue functioning, market relationships survive and capacity expands organically rather than requiring constant intervention.

We have seen this principle create lasting results across programmes in agriculture, entrepreneurship, livelihoods, and local economic development.

The objective is not simply to deliver a solution, it’s to create the conditions for continued progress long after the initial intervention has ended.

This also applies to infrastructure. A city can finance a transport network or build roads, transit systems, and public services, but the long-term value of those investments depends on whether institutions can maintain them, whether financing remains sustainable, whether governance structures support adaptation, and whether communities continue to derive value from them.

As India moves toward its Viksit Bharat @2047 ambition, this shift in thinking may prove just as important as the investments themselves.

Infrastructure has always been about enabling growth. The next challenge is ensuring that the systems we build can evolve alongside the communities, economies, and environments they serve.
