In Mexico, as in many other countries, the agricultural sector is one of the largest water consumers, accounting for 67.52% of total water use. This makes sustainable water management essential to ensure food security and preserve the country’s water resources.
Currently, small-scale agriculture, which covers almost 72% of the territory, predominantly relies on gravity irrigation systems (also known as furrow or flood irrigation), which have low efficiency rates, ranging between 20% and 40%. Through our fieldwork with farmers, we’ve demonstrated that it is possible to increase these efficiencies up to 80%, with an effective cost-benefit ratio.
The optimization of irrigation in agriculture largely depends on the human factor, which is key to achieving significant and sustainable long-term water savings. Collaboration between technical knowledge and the farmer’s experience is crucial: while scientific tools and methods provide technical solutions, their effective implementation depends on the farmer’s commitment and ability to adapt these solutions to local conditions.
Aware of the unique characteristics of Mexican farmlands, we have developed an intervention framework focused on improving irrigation efficiencies by providing personalized technical advice to each farmer. This individualized approach allows us to deeply understand the initial conditions, such as the specific characteristics of the land, the available irrigation infrastructure, and the specific needs of the crops. In this way, we can propose tailored improvements that not only increase irrigation efficiency and reduce water consumption, especially groundwater, but also prevent pests and diseases and improve crop yields.
The methodology starts by thoroughly understanding the farmers’ usual irrigation practices: how, how much, and when do they irrigate? Why do they do it that way? This analysis, along with field measurements, allows us to offer customized recommendations that optimize irrigation within their plots.
After more than two years of close work with farmers, we’ve noticed that many still follow habits passed down through generations, which are not always the most appropriate for sustainable resource management. Changing these habits is not easy, which is why establishing trust from the outset is essential. We encourage active farmer participation throughout the process, considering their input on proposed improvements, assisting them with implementation, and supporting them in recording field data. Moreover, we seek complementary resources to improve irrigation infrastructure and offer comprehensive advice that goes beyond efficient water use, also addressing productive and commercial aspects.
Another key aspect of our methodology is returning the information collected during each production cycle to the farmers, enabling them to observe and analyze the benefits and impacts of improved irrigation practices. This not only promotes greater awareness of responsible water use but also improves decision-making in their irrigation units, empowering farmers to take responsibility for their limited resources.
We are convinced that education and awareness in the communities where we implement our projects are crucial to addressing water stress. Through group workshops, we provide updated information on water challenges, best practices for efficient use, and farmers’ rights and responsibilities. This fosters deeper reflection on the environmental consequences of conventional agriculture, promoting a sustainable approach tailored to current challenges.
