Farmers across Khyber Pakhtunkhwa are beginning to adopt smart soil moisture sensor technology that is enabling more efficient use of water while improving agricultural productivity. The initiative is providing farmers with real time data on soil moisture levels, helping them make informed irrigation decisions rather than relying on traditional schedules or estimation. Early results indicate that the technology is contributing to significant water savings, reduced fuel and energy costs, and measurable improvements in crop yields, particularly in areas already facing pressure from climate variability and water shortages.
The soil water moisture sensor array has been installed at the Tarnab Research Farm as well as in selected farming locations across the province, with 50 sensors deployed in Charsadda district and 60 installed in Mansehra. These sensors continuously monitor moisture levels at different depths and transmit data directly to farmers through a mobile application. The system uses a simple three signal indicator, similar to traffic lights, to communicate whether irrigation is required, allowing farmers to quickly understand crop water needs without technical complexity. This approach minimizes over irrigation and helps preserve increasingly scarce water resources.
According to Dr Gulzar Ahmed, Research Officer at the Pakistan Scientific Research Centre, the project is being implemented in collaboration with the International Water Management Institute. He explained that farmers are now able to check soil conditions remotely and decide whether irrigation is necessary, preventing unnecessary water use. The initiative also supports broader water related research and aims to reduce overall agricultural water consumption. Consultations are ongoing with international water focused institutions to further strengthen the programme and align it with global best practices in water conservation and agricultural management.
Project lead Kifayat Zaman stated that the initiative is part of a UK funded programme titled Water Resources Accountability in Pakistan, which was launched in Punjab in 2021 and expanded to Khyber Pakhtunkhwa in 2024. He noted that farmers who previously irrigated their fields four to six times per season are now doing so only three to four times, resulting in water savings of approximately 25 to 30 percent. Beyond conservation, research findings suggest crop yields have increased by 15 to 20 percent, offering both environmental and economic benefits. Farmers who rely on tube wells powered by electricity or solar systems have also seen reductions in operational expenses due to fewer irrigation cycles.
Zaman added that the sensors are designed to improve water demand assessment, supply management, and governance within the water sector by strengthening coordination among government institutions. Climate related challenges such as erratic rainfall patterns, rising temperatures, and prolonged water shortages are already affecting agricultural productivity across the province. By integrating real time data into irrigation practices, farmers are better positioned to optimize water use while maintaining stable crop output. The initiative reflects growing efforts to integrate digital tools into agriculture as part of Pakistan’s broader push toward climate resilient and resource efficient farming systems.
