Farming Techniques for Improving Food Production
To ensure global food security is achieved, it is essential that the efficiency of food production is improved:
Food chains
- Only about 10% of energy passes from each trophic level to the next.
- Therefore, shortening food chains will greatly increase efficiency.
Livestock
- Energy will always be transferred from livestock to the environment due to essential processes, like moving or maintaining body temperature.
- Limiting the amount of energy wasted in this way helps improve food production efficiency.
High protein foods
- Feeding animals foods that are high in protein helps boost their growth rates.
