What Is Sustainable Gastronomy?

Gastronomy, or the “art of food,” refers to local food, cuisine, or a cooking style from a particular region. On the other hand, sustainable gastronomy emphasizes respecting the environment, biodiversity, and local traditions when it comes to food.

It involves not just sustainable agriculture but also ingredient origins, harvest methods, transportation, and food preparation. It supports local economies, culinary traditions, and nutritious food. Seasonal, local produce consumption reduces waste, while restaurateurs can emphasize local, waste-minimal meals.

With everyone’s efforts involved, responsible consumption and production support several UN Sustainable Development Goals.

Why Sustainable Gastronomy Day Matters

By choosing locally produced, sustainable foods, we can take direct action against hunger and malnutrition and promote healthier lives. On a global level, it reduces carbon footprint and, therefore, combats climate change.

Moreover, it helps support local economies, reduces the need for long-distance transportation, and promotes energy conservation and community development. It even encourages the use of diverse species and varieties, helping to preserve the planet's biodiversity.

Lastly, it minimizes food waste by using every part of an ingredient and composting organic waste, resulting in less landfill waste and fewer methane emissions.

Data and Statistics

The UNEP Food Waste Index Report mentioned that each of us wastes approximately 79 kilograms of food annually, or over a billion meals.

Secondly, FAO states that food waste, if it were a country, would be the third-largest emitter of greenhouse gases after China and the USA.

How to Practice Sustainable Gastronomy

  • Choose locally sourced and in-season foods.
  • Buy from local food markets or small producers. It boosts the local economy, reduces the carbon footprint of food transportation, and keeps culinary traditions alive.
  • Plan your meals and store your food properly to reduce food waste.
  • Compost your leftovers to turn organic waste into nutrient-rich soil.
  • Prioritize organic and sustainably-produced foods to support soil health and biodiversity.
  • Choose sustainably caught or farmed seafood to preserve marine ecosystems.
  • Cut back on meat and dairy and add more plant-based meals to your weekly menu to reduce the strain on our natural resources.
  • Understand the environmental impact of your food choices. Read food labels and expiration dates. Research brands' sustainability practices. Learn about the issues plaguing the food industry.
