Daniel Madariaga. The water footprint is an essential concept in sustainable water management, encompassing the total amount of water used both directly and indirectly in the production of goods and services.
This metric, developed by Professor Arjen Y. Hoekstra from the University of Twente, provides a comprehensive perspective on human impact on water resources and water availability across various economic sectors and geographical regions.
Water plays a crucial role in agricultural production and is fundamental to global food security. Irrigated agriculture, which occupies 20% of the world’s cultivated land, contributes to 40% of total food production, according to data from the World Bank.
In countries like Mexico, with a strong agricultural tradition, 76% of potable water is used in agricultural activities, a proportion slightly higher than the global average of around 70%, according to World Bank estimates. Therefore, proper water management in agriculture is critical to ensure the productivity and sustainability of the food system.
Daniel Madariaga on How Food Systems are an Alternative for Sustainability
An example of how the water footprint is calculated in agriculture involves the amount of water used throughout the entire life cycle of a crop, including irrigation, evaporation, and the water incorporated in inputs like fertilizers and pesticides. This information is collected and used to calculate the total water footprint of the crop, providing a quantitative measure of water use associated with its production.
Additionally, the relationship between the water footprint and agriculture is complex and also includes aspects such as food processing. This phase involves activities like cleaning, washing, sorting, cutting, cooking, packaging, and preserving agricultural products.
Each of these activities requires water, whether for cleaning, cooking, or as part of the production process. For example, in the meat industry, processing meat and producing meat products require large amounts of water for washing and refrigeration.
Given this context, it is essential to adopt sustainable agricultural practices that minimize excessive water use and promote efficiency in its utilization, such as Organic Biocapacity Food Models (MABO) and Environmental Measures for Organic Zones (MAZO).
Moreover, collaboration between the public sector, private sector, and civil society is crucial to address challenges related to water footprint and agriculture. Only through a collaborative and committed approach can we develop effective strategies to promote responsible water management and ensure the availability of water resources for future generations.
