Sustainable Food Strategies: Global Agricultural Solutions
Year 11 Geography Exploring methods to increase food supply Moving towards sustainable agriculture
The Global Food Challenge
World population projected to reach 9.7 billion by 2050 Need to increase food production by 70% Climate change threatens agricultural productivity Limited arable land and water resources
Traditional Irrigation Systems
Drip irrigation reduces water waste by 30-50% Sprinkler systems for large-scale farming Canal and furrow irrigation in developing regions Smart irrigation using sensors and automation
Soil-less Growing: Hydroponics vs Aeroponics
{"left":"Uses nutrient-rich water solutions\nControlled environment agriculture\nHigher yields in smaller spaces\nReduced pesticide use","right":"Plant roots suspended in air\nNutrient mist delivered directly to roots\n90% less water than traditional farming\nFaster growth rates"}
The New Green Revolution
Genetically modified crops with higher yields Drought-resistant and pest-resistant varieties Golden Rice enriched with Vitamin A CRISPR gene editing technology Precision breeding for climate adaptation
Case Study Analysis: The Cerrado, Brazil
Research Brazil's Cerrado agricultural development Identify advantages: increased soy production, economic growth Identify disadvantages: deforestation, biodiversity loss Present findings to the class
Sustainable Agriculture Philosophy
"Sustainable agriculture must nurture healthy ecosystems and support the sustainable management of land, water and natural resources, while ensuring world food security." - FAO
Sustainable Food Production Methods
Local Success Story: Cuba's Urban Agriculture
Organopónicos - urban organic gardens Produces 50% of Havana's vegetables Low-cost, appropriate technology solutions Community-based food security Reduced transportation and packaging
Reflection and Future Action
Which sustainable food strategy would work best in your local area? How can individuals contribute to sustainable food systems? What barriers exist to implementing these strategies globally?
