Executive Summary

The agricultural sector faces the challenge of increasing food production to meet the demand caused by global population growth. In this scenario, irrigation and family agriculture (FA) play a central role. FA is the most widespread form of production in the world, representing more than 90% of all agricultural holdings (500 million) and contributing more than 80% of food production. Most of the FA in Latin America and the Caribbean uses irrigation based on empirical knowledge, which led to an inefficient water management. The Irrigation Advisory System (SAR) provides farmers with information to achieve a more efficient irrigation management, which leads to increasing crop yields. The general objective of the project is to identify how to reduce the yield gap in a group of crops through the use of irrigation schedules adjusted to the water requirements.

The technological solution

The growing access to the Internet, mobile phones, remote data transmission and satellite products are opportunities to improve the process of extension and transfer of knowledge to FA. By combining direct measurements of soil moisture and the aforementioned technologies, this information will be made available to indicate to farmers when and how much to irrigate.

Results

The main result of the project is the development of the Irrigation Advisory Service (SAR) platform, which provides an answer to the two basic questions of irrigation scheduling: when and how much to irrigate? The SAR shows, graphically and numerically, the availability of water in the soil. When the soil water content falls below a threshold (which depends mainly on the crop and soil type), the irrigation alert is given. The SAR has been tested on alfalfa, cotton, strawberry, tomato, pepper and bean. Preliminary results show that adjusted irrigation schedules significantly increases crop yields: alfalfa 33%, cotton 67%, pepper 65%, strawberry 52%, beans 22% and tomato 62%. Complementary results of the project are: a) strengthening agrometeorological information networks through the installation of 6 automatic weather stations, 5 having online access; b) the use of satellite images for soil moisture estimation through algorithms, using predictor variables, such as bulk density and texture of soil, and spectral indices; c) the bases for scaling up the project were established and its results were communicated through reports, workshops, meetings and seminars.
