Food production has more than doubled and diets have become more varied, over 800 million people are hungry, over 2 billion suffer from micro nutrient deficiencies and over 2 billion people are overweight or obese. This indicates that today’s food systems are broken. They are not delivering food security and healthy food for everyone nor are they sustainable. With the global population predicted to rise to 9.5 billion by 2050, the food systems require a transformational change.
1. What sustainable food systems can be put forward to minimize food consumption impacts?
A sustainable food system is a food system that delivers food security and nutrition for all in such a way that the economic, social and environmental bases to generate food security and nutrition for future generations are not compromised. This means that: – It is profitable throughout (economic sustainability); – It has broad-based benefits for society (social sustainability); and – It has a positive or neutral impact on the natural environment (environmental sustainability).
2. How can we improve our food production practices to increase access of food to everyone?
The food system is composed of subsystems (e.g. farming system, waste management system, input supply system, etc.) and interacts with other key systems (e.g. energy system, trade system, health system, etc.). But as in any crisis, there is a place for opportunities! And here there is plenty of room to improve!
Solve the challenge put forward by the city of Dar es Salaam of mobility, and waste management.
