Energy Security

Ensuring reliable, affordable, and sustainable energy sources to meet the needs of a population or country.

Global Hunger Index (GHI)

A measure of world hunger calculated based on undernourishment, child underweight, and child mortality rates.

Food Security

The state where all people, at all times, have physical, social, and economic access to sufficient, safe, and nutritious food.

Resource Management

The efficient and sustainable utilization, distribution, and conservation of resources to meet current and future needs.

Irrigation

Increasing food production by providing water to crops, with the potential to improve yields in regions lacking irrigation systems.

Green Revolution

Introduction of modern farming techniques like fertilizers, pesticides, and high-yield crop varieties in low-income countries to enhance agricultural productivity.

Biotechnology

Utilizing selective breeding or genetic modification to develop plants and animals with desired traits, such as disease resistance in wheat.

Organic Farming

Growing food using natural methods without artificial fertilizers or pesticides, aiming for environmental sustainability and minimizing ecosystem damage.

Sustainable Fishing

Involves catching fewer fish, using better net designs, and traditional fishing methods to prevent overfishing and preserve fish populations.

Sustainable Meat Production

Utilizing grass as animal feed to reduce resource consumption, as meat production is resource-intensive and requires significant amounts of grain and water.

Seasonal Food Consumption

Traditional practice of eating food in season to reduce food miles, electricity use, and environmental impact.

Reduction of Food Waste

Promoting sustainable practices by buying only needed food to minimize waste and ensure surplus food can feed others.
