Project description

Aim: Large tracts of land in the delta region of Bangladesh are left fallow or are cultivated with low input crops during the dry winter months. Surface water based irrigation opens up new opportunities for sustainable intensification by enabling the production of a high yielding crop. To ensure an optimal use of irrigation pumps, CIMMYT (International Maize and Wheat Improvement Center) is currently developing an advisory system for irrigation scheduling, which calculates a daily soil water balance and estimates crop water use based on ground cover derived from satellite data. The project aims to replace satellite data by RGB photos taken with smartphones as these do not depend on weather conditions and are accessible to famers.

Objective: The overall objective of the proposed project is to optimize water resource management by enabling farmers to obtain field-specific irrigation advice, which when mobilized, will in turn will increase food production and food security. Use of intensive, cost-effective irrigation that boosts yield will also generate more cash income for farm households, as a higher share of farm produce can be sold on the market. Business opportunities for ISPs will also increase. Our specific objectives are:

  • Develop an app that enables farmers to capture field specific ground cover photos with an off-the-shelve smart phone.
  • Automatically analyse the RGB photos and estimate percent ground cover.
  • Transmit ground cover estimates to a server where they will be integrated into the irrigation advisory system in order to schedule irrigation requirements in real time.
  • Integrate the ground cover estimates into the irrigation advisory system.
  • Ensure that women and illiterate farmers are included in the training and will get access to the technology and enable them to potentially use the phones for other applications.
  • Determine what the best design for a user friendly app is, so that there are no barriers to access.

Method: The project will not only focus on a thorough validation and calibration of the new system, but ensure proper training of potential users, including women and illiterate farmers.

Country: Bangladesh.

Dutch policy goals: Increased sustainable agricultural production; and Improved access to better nutrition.

Duration: January 2016 – January 2019
