The Food-Water-Energy Nexus Concept - Summary

• 1. Core Concept:

- The Food-Water-Energy Nexus highlights the critical interdependence of the three fundamental resources for life and the economy.

- Management of one resource directly affects the availability and sustainability of the other two.

• 2. Main Objectives:

- Increase efficiency in resource use to meet increasing demand.

- Reduce environmental impacts, including greenhouse gas emissions and water consumption.

- Ensure resource security to prevent conflict and social instability.

• 3. Key Principles:

- Sustainability: Resources should be used without compromising their future capacity for regeneration.

- Efficiency: Losses of food, water and energy should be minimized.

- Integration: Policies and solutions should be coordinated and avoid trade-offs that may create problems in other areas.

• 4. Practical applications:

- In agriculture: reducing water consumption through efficient irrigation and reducing energy consumption in production.

- In the energy sector: promoting renewable sources that consume less water.

- In water management: efficient infrastructures and policies to reduce waste.

• 5. Challenges addressed:

- Global population growth, which determines a higher demand for food, water and energy.

- Climate change, which affects natural resources.

- Rapid urbanization, which increases demand and fragmentation of resources.

• 6. Global impact:

- It is a global strategic framework integrated into the policies of many countries and international organizations for sustainable development.

- It has been used in the development of environmental and food security policies, but also for the preparation of climate strategies.
