Overview

The world’s population grows toward 9 billion by 2050. This trend makes sustainable food production a key need. This review shows green technology trends and challenges. It points us toward eco-friendly agriculture and food processing.

Key Challenges in Food Production

• Population Growth & Urbanization: People move from farms to cities. This shift pushes a need for industrial food systems.
• Environmental Impacts: Land changes and wildlife loss hurt the Earth. Extra nitrogen and phosphorus from fertilizers damage water and land. Climate change, water shortages, and pesticide use worsen the strain.
• Food Waste & Malnutrition: Food waste may reach 30-50% globally. Even with higher production, malnutrition persists. Three billion people lack enough food; many suffer low iron and calories.

Defining Green Technologies in Food Systems

• Green Technology: Use science, green chemistry, and clear tests to protect nature.
• Green Growth (OECD Definition): Grow the economy while keeping nature safe. This view stops harm to nature and its variety.

Trends Driving Green Food Production and Processing

1. Sustainable Agriculture
   Farmers use organic methods and less harsh chemicals. Local practices support wildlife diversity.

2. Energy and Material Stewardship
   Processors choose energy-efficient machines and reduce waste in every step.

3. Emerging Technologies
   New methods lower toxin levels and boost energy savings.

4. Social and Market Influences
   Shoppers seek organic, local, “free-from,” whole, and fair-trade foods. Their choices drive industry changes.

5. Life Cycle Assessment (LCA)
   Experts use LCA to track a product’s impact from start to finish. This tool helps spot ways to improve sustainability.

Food Supply Chain Evolution

Food production started as local and seasonal. Over time, it grew into complex supply chains with many middlemen. Today, there is a call to rebuild these systems with green methods at each stage: production, processing, packaging, and distribution.

Recommendations and Strategies

• Integrate Green Technologies: Use eco-friendly methods in farming and processing to cut waste and resource use.
• Biodiversity Preservation: Support diverse farming practices to build resilient ecosystems and diets.
• Improve Resource Efficiency: Use water wisely, lower fertilizer overuse, and shift to renewable energy.
• Consumer Education: Help buyers learn about green food choices and sustainable habits.

Conclusion

Population growth and environmental issues create urgent calls for green technology. Sustainable practices mix with smart resource use to secure food and health for the long term. These ideas help form a greener, healthier food future.

For practitioners and researchers in sustainable food systems, this review lists key issues and ways forward. It builds a base for greener agrifood industries.
