Water Food Energy Nexus – blue aquaculture as an integrative part to minimize use of resources (water, nutrients, energy) for animal and plant production

Water is a prerequisite for food production which requires also nutrients and energy. Vice versa alternative energy production by biogas plants is based on biomass derived from agriculture. Thus agricultural food production seems to be the most important integrative part concerning the water-food-energy nexus.

Aquaculture is the fastest growing agriculture sector meeting the increasing needs of the rapidly expanding global population for high quality animal proteins. Currently, worldwide production is focused on freshwater aquaculture of fish and is consequently competing for limited freshwater resources. Hence, particularly in the light of future development, aquaculture production is limited in land available for agricultural production and global freshwater reserves. The necessity towards minimizing resources (water, nutrient, energy) meeting sustainability is referred to as “blue aquaculture” and requires urgently the introduction of new recently developed integrative concepts to achieve a sustainable connection of the water-food-energy nexus.

Target groups

Stakeholders concerning water/waste water management, power plants (conventional and alternative production), agriculturists (focus on integrated aquaculture), bioeconomists, ecosystem modelling, etc.

Workshop responsibles


Workshop outline

Three initiating talks with main focus on water, food (aquaculture as integrated part), and energy, respectively. Building working groups consisting of different expertises to rule out the possibilities and limitations of integrating water-food-energy nexus towards sustainability.

Main-goal and objectives

Bringing together people with different expertises to discuss and evaluate the potentials and limitations for integrative sustainable management of water-food-energy nexus. One objective should be to initiate a manuscript for a theoretical conception paper by all participants and secondly trying to evaluate the potential for a concept of joint research and cooperation among participants.

In countries around the world, meeting daily energy needs is dependent on water. Finding sufficient water resources to produce the required energy, however, and then appropriately allocating the limited supply, is becoming more difficult.

Drought and rising temperatures are forcing water managers across the country to scramble for ways to produce the same amount of power from the hydroelectric grid with less water, including from behemoths such as the Hoover Dam. Hydropower is not the only part of the nation’s energy system that appears increasingly vulnerable to the impact of climate change, as low water levels affect coal-fired and nuclear power plants’ operations and impede the passage of coal barges along the Mississippi River.
