🚣🏼♀️International Development and Sustainability Unit 10 – Agriculture & Rural Dev: Food Security
Food security is a complex issue encompassing availability, access, utilization, and stability of food supplies. It's influenced by factors like agricultural production, income, nutrition, and environmental conditions. Understanding these elements is crucial for addressing global hunger and malnutrition.
Historical developments in agriculture, from ancient irrigation techniques to the Green Revolution, have shaped our food systems. Today, challenges like climate change, population growth, and resource scarcity threaten food security. Sustainable practices and rural development strategies are key to ensuring future food supplies.
Food security exists when all people have physical, social, and economic access to sufficient, safe, and nutritious food (FAO definition)
Food availability refers to the supply of food through production, distribution, and exchange
Determined by factors such as agricultural production, food stocks, and trade
Food access is the ability to acquire sufficient resources to obtain appropriate foods for a nutritious diet
Influenced by income, food prices, and social and political factors
Food utilization encompasses the way the body makes the most of various nutrients in food
Affected by food preparation, diversity of diet, and intra-household distribution of food
Stability of food supply and access is critical for long-term food security
Impacted by weather conditions, political instability, and economic factors (price fluctuations)
Malnutrition can result from inadequate food intake, poor diet quality, or health issues that impair nutrient absorption and utilization
Hidden hunger refers to micronutrient deficiencies (vitamin A, iron, zinc) that can occur even when caloric intake is sufficient
Historical Context of Agricultural Development
Agriculture emerged independently in multiple regions (Fertile Crescent, China, Mesoamerica) around 10,000 years ago
Domestication of plants and animals allowed for settled communities and population growth
Irrigation and water management techniques (Nile River, Indus Valley) enabled more reliable food production
The Columbian Exchange introduced new crops (potatoes, maize) and livestock (cattle, pigs) between the Old and New Worlds
The Green Revolution of the 1950s-1970s significantly increased agricultural productivity through high-yielding crop varieties, fertilizers, and pesticides
Helped to reduce hunger and malnutrition in many developing countries
The industrialization of agriculture in the 20th century led to mechanization, monocultures, and the rise of agribusiness
Globalization has increased the interconnectedness of food systems and the distance food travels from farm to plate
Challenges to Global Food Security
Population growth and urbanization increase demand for food while reducing available agricultural land
Climate change impacts agricultural productivity through changes in temperature, precipitation, and extreme weather events (droughts, floods)
Affects crop yields, water availability, and the spread of pests and diseases
Land degradation and soil erosion reduce the productivity and sustainability of agricultural systems
Water scarcity and competition for water resources (industry, urban areas) limit agricultural production
Poverty and inequality limit access to food, land, and other resources for many smallholder farmers and rural communities
Food loss and waste occur throughout the supply chain, from production to consumption
Estimated that one-third of all food produced is lost or wasted globally
Political instability, conflict, and displacement disrupt food systems and contribute to food insecurity
Changing diets and the rise of processed foods contribute to malnutrition and diet-related health issues (obesity, diabetes)
Sustainable Agriculture Practices
Agroecology applies ecological principles to the design and management of agricultural systems
Emphasizes diversity, resilience, and adaptation to local conditions
