Food Security Management Strategies (Cambridge (CIE) AS Environmental Management): Revision Note

Managing Food Security

• Food security is a critical global challenge that requires comprehensive strategies to ensure access to safe, nutritious and sufficient food for all people:

  • Various approaches and interventions have been implemented to manage food security, addressing issues such as production, distribution, waste and access to food resources

Strategies for Managing Food Security

• Subsistence agriculture:

  • Subsistence agriculture focuses on producing enough food to meet the basic needs of a household or community

  • It involves small-scale farming practices, often using traditional methods and relying on locally available resources

  • Strength: provides immediate, short-term food security for local communities, reducing reliance on external food sources

  • Limitation: limited scalability and productivity compared to commercial farming methods, may not meet long-term food demands

• Increasing food production:

  • Intensification: increasing agricultural productivity on existing land through practices such as improved crop varieties, irrigation and fertilisation

  • Extensification: expanding agricultural land (i.e. using new land) to increase overall food production, often through deforestation or conversion of natural habitats

  • Strength: boosts food availability and accessibility, addressing immediate hunger and malnutrition concerns

  • Limitation: intensification and extensification practices may lead to environmental degradation and loss of biodiversity, compromising long-term sustainability

• Improved agricultural techniques and efficiency:

  • Aquaculture and hydroponics: cultivating aquatic organisms and plants in controlled environments, providing alternative, more efficient sources of food production

  • Selective breeding and GM crops: developing crops with desirable traits, such as pest resistance and higher yields, to improve agricultural productivity

  • Use of agrochemicals: controlling limiting factors such as pests, weeds and diseases through the use of fertilisers, herbicides, fungicides and biological control methods

  • Strength: enhances crop yields and resilience to pests and diseases, improving food security and farmer livelihoods

  • Limitation: dependency on agrochemicals may contribute to soil degradation, water pollution, and health risks for farmers and consumers

• Livestock management:

  • Reducing livestock: managing livestock populations to allocate resources more efficiently and reduce environmental impacts, such as land degradation and greenhouse gas emissions

  • Promoting crop cultivation: increasing the focus on growing crops for direct human consumption rather than feeding livestock

  • Strength: diversifies food sources and income streams for farmers, contributing to household food security

  • Limitation: high resource requirements and environmental impacts associated with livestock production, such as land degradation and greenhouse gas emissions

• Reducing food waste:

  • Implementing measures to minimise food losses and waste throughout the food supply chain, including production, distribution, storage and consumption

  • Strength: maximises the efficiency of food distribution and utilisation, ensuring more equitable access to food resources

  • Limitation: logistical challenges in implementing waste reduction strategies across the entire food supply chain

• Large-scale food stockpiling:

  • Establishing reserves of staple foods to buffer against supply disruptions, price fluctuations and emergencies, ensuring food availability during times of scarcity

  • Strength: provides a buffer against food shortages and price fluctuations, ensuring food security during emergencies

  • Limitation: costly to establish and maintain stockpiles, and may lead to inefficiencies if not managed properly

• Improving transportation:

  • Enhancing infrastructure and logistics to increase the efficiency of moving food from production areas to markets and distribution points, reducing food spoilage and losses

  • Strength: enhances food accessibility and reduces wastage by reducing transportation barriers (i.e. factors that slow down the transport of food products)

  • Limitation: reliance on fossil fuels for transportation contributes to carbon emissions and climate change, posing long-term sustainability challenges

• Protecting pollinating insects:

  • Implementing conservation measures to safeguard pollinator populations, such as bees, which play a crucial role in crop pollination and food production

  • Strength: ensures the continuity of pollination services critical for agricultural productivity and food security

  • Limitation: addressing pollinator declines requires comprehensive conservation efforts and policy interventions, which may take time to implement and yield results

• World Food Programme and Food Aid:

  • Supporting international organisations and initiatives, such as the World Food Programme, to provide emergency food assistance and long-term development aid to vulnerable populations

  • Strength: provides crucial food assistance to vulnerable people during emergencies and humanitarian crises

  • Limitation: dependency on external aid may undermine local food production systems and long-term food security objectives in countries receiving aid

• Rationing:

  • Implementing rationing systems during times of food scarcity or crisis to ensure consistent, fair distribution and access to essential food supplies

  • Strength: ensures equitable distribution of limited food supplies during times of scarcity, preventing hoarding

  • Limitation: rationing may lead to social tensions and inequities if not implemented fairly and transparently, and may not address underlying causes of food insecurity
