• The IWACA-TECH Project

    Improving water use efficiency at irrigation systems using advanced Remote Sensing Technology.

    The IWACA-TECH Project

    A software based solution that provides site-specific irrigation recommendations without the need of upgrading the irrigation system

    Using actual satellite and ground observations to make better decisions

  • Who We Are

    The IWACATECH project is funded by the Dutch Partners for Water program and brings together Dutch and Mozambican Partners. Satellite scientists, water experts, sugar producers and local operators will jointly develop a novel service for large irrigation schemes which will improve the water efficiency, crop yield and water productivity without increasing the consumptive use.

    Why we do this

    To contribute to solving the increasing competing demands for water in river basins it is necessary to focus on the largest water consumer, irrigation. The key question is: how to do this cost-effectively. One way is to change the irrigation technology of an entire irrigation system, but changing the hardware is often too expensive or almost impossible to achieve. Our solution is to focus on alternative ways to improve current water allocation and water operations, namely through a combination of novel cost-effective information technologies that only recently have been developed.

    Our Work

    Agriculture in Africa is facing difficult challenges in the coming decades. Climate change in combination with the exponential population growth will further threaten production and require a smart usage of the vulnerable water resources of our planet.

    With the recent launch of a series sophisticated satellites from different space agencies we are now in the position to measure water availability within an agricultural field.


    The IWACA-TECH project uses this new data stream to improve water use of irrigated fields without losing productivity.

    How we do it

    By combining smart mobile systems used by operators in the field with advanced satellite data, the project aims to boost both the water use efficiency and water productivity of large scale irrigation systems.


    The measurements and control actions are performed by human operators who are guided by a mobile application. The operators dynamically interact with a control system where their steps and the water demand from the crop are updated with satellite information.

    Dutch water expertise

    Agriculture is the largest water consumer in many river basins, and its expanding water requirements threaten the water availability for other users, including towns and cities as well as ecosystems, which include valuable estuarine and deltaic ecosystems such as mangroves and local fisheries.


    Irrigated agriculture is also known to be a relatively inefficient water user. By increasing the water use efficiency of agriculture, which is one of the priority goals of Dutch development cooperation, the water security of other users will be enhanced.
