IN PURSUIT OF LOST WATER PART 1: Inefficient Irrigation in Agriculture

Drip irrigation system in agriculture

Climate change is becoming increasingly evident across Türkiye, making water loss no longer a concern limited to environmentalists or public institutions. Drought, declining reservoir levels, rising temperatures, and population growth have turned water security into a strategic issue for economic development, industrial production, and national resilience. Yet much of the public discussion surrounding water conservation continues to focus on individual consumption habits. Taking shorter showers, turning off the tap while brushing teeth, or installing water-saving fixtures are all worthwhile measures. However, if Türkiye is to address its growing water challenge, the primary focus must shift away from households and toward agricultural fields, water distribution networks, and production systems.

Türkiye is not considered a water-rich country in terms of renewable freshwater resources per capita. With continued population growth, rapid urbanization, and the accelerating impacts of climate change, the country is expected to face increasingly severe water scarcity in the coming decades. Despite this reality, a substantial share of available water resources is still used inefficiently or lost before it can provide economic or social value.

Where Is Türkiye’s Water Used?

Official water management data paint a striking picture. Approximately three-quarters of all freshwater withdrawals in Türkiye are used for agricultural irrigation, while domestic consumption and industrial use account for significantly smaller shares of total water demand.

This distribution challenges the widespread perception that household consumption is the primary cause of the country’s water crisis. While reducing shower times or avoiding unnecessary water use at home are certainly positive actions, the greatest improvements in water efficiency can only be achieved through reforms in the agricultural sector, where the vast majority of the country’s freshwater resources are consumed.

The Hidden Challenge: Inefficient Irrigation

Traditional flood irrigation remains common across many agricultural regions of Türkiye. Under this method, large volumes of water are released onto fields, with a significant portion being lost through evaporation, seepage, and surface runoff before crops are able to absorb it.

By contrast, modern drip irrigation and precision irrigation technologies have the potential to dramatically reduce water consumption while maintaining, or even increasing, agricultural productivity. Water-efficiency projects are expected to become one of the defining agricultural policy priorities of the coming decade, particularly in drought-prone regions such as Central Anatolia, Southeastern Anatolia, and the Aegean.

The issue extends beyond the volume of water applied. In many farming areas, irrigation decisions are still based on routine schedules rather than actual crop requirements. Technologies such as soil moisture sensors, remote sensing systems, and AI-powered irrigation management platforms enable farmers to deliver water precisely when and where crops need it, minimizing waste while maximizing productivity.

Cities Are Losing Water Too

Another critical dimension of the water crisis lies within urban distribution systems. In many Turkish cities, a considerable amount of treated water never reaches consumers. Aging pipelines, leakage, pressure management problems, and outdated infrastructure result in the loss of millions of cubic meters of water every year.

This reality highlights the importance of reducing losses within existing distribution systems before investing solely in new reservoirs or additional water supply projects. Although some municipalities have begun deploying smart meters, SCADA systems, and digital monitoring technologies to improve network efficiency, substantial opportunities for further improvement remain nationwide.

Industry Faces New Water Risks

Although industry represents a smaller share of total water consumption than agriculture, it may become one of the sectors most vulnerable to the economic consequences of water scarcity.

Industries such as steel, textiles, food processing, chemicals, and energy production rely on secure water supplies as a fundamental production input. Water restrictions resulting from prolonged drought could directly affect manufacturing capacity, operating costs, and international competitiveness.

As a result, industrial companies around the world are increasingly investing not only in energy efficiency but also in water efficiency. Water recycling systems, closed-loop water management, wastewater recovery, and water reuse technologies are becoming standard components of modern industrial sustainability strategies.

Is the Real Problem Water Scarcity or Water Management?

Türkiye’s situation demonstrates that the country’s water challenge cannot be explained solely by declining rainfall. The more fundamental question is how effectively existing water resources are managed. It is therefore unsurprising that future water policies are expected to focus less on constructing new dams and more on using existing water resources more intelligently and efficiently.

This raises an important question:

If agriculture accounts for the overwhelming majority of Türkiye’s water consumption, why have the modern irrigation technologies that have transformed farming in some of the world’s driest regions not yet been widely adopted across the country?

In the second installment of this special report, we examine how drip irrigation revolutionized agriculture in arid environments and explore the experiences of countries that have become global leaders in water efficiency—and what lessons Türkiye can draw from their success.
