Feed the world
From regenerative farming to seaweed in cattle feed, scientists at Queen’s University Belfast are discovering practical solutions that will help people eat better but won’t fuel the climate crisis
TL;DR
- The global food sector is responsible for approximately 30% of human-caused greenhouse gas emissions.
- A coordinated approach involving environmental research, nutritional analysis, and agricultural innovation is needed for a sustainable food system.
- Queen's University Belfast's Institute for Global Food Security conducts research across the entire food production chain.
- Dietary research indicates that flavonoids reduce dementia risk, and plant-based diets high in fruits, vegetables, and whole grains decrease type 2 diabetes risk.
- Adding seaweed, particularly red seaweed asparagopsis, to cattle feed can significantly reduce methane emissions.
- Regenerative farming, which prioritizes soil health and biodiversity, is considered vital for sustainable food production.
- A holistic, system-based view is necessary to enhance the sustainability of food production, considering both the environment and human health.
