Food security in a perfect storm: using the ecosystem services framework to increase understanding.

Area of Science:

• Agricultural Science
• Environmental Science
• Development Studies

Background:

• Global food security faces unprecedented challenges due to climate change and population growth.
• Past agricultural intensification efforts have often degraded ecosystems and reduced biodiversity, disproportionately affecting vulnerable populations.
• Achieving food security is crucial for attaining other Millennium Development Goals (MDGs).

Purpose of the Study:

• To propose a framework integrating ecosystem services (ES) and policy response mechanisms for sustainable food security.
• To highlight the interconnectedness of agro-ecosystems and surrounding natural ecosystems.
• To illustrate the ES approach to food security using a case study from Malawi.

Main Methods:

• Utilized the ecosystem services (ES) framework.
• Integrated the Driver-Pressure-State-Impact-Response (DPSIR) policy response framework.
• Conducted a multi-disciplinary research project (ASSETS) with a case study in Zomba district, Malawi.

Main Results:

• Demonstrated that food security can be achieved concurrently with the maintenance of healthy ecosystems.
• Highlighted the flow of services between agro-ecosystems and surrounding natural environments.
• Provided a practical illustration of the ES approach in a real-world context.

Conclusions:

• The proposed integrated framework offers a viable strategy for addressing the complex challenges of food security and environmental sustainability.
• Recognizing and managing ecosystem services is essential for resilient food systems.
• Policy interventions must consider the broader ecological context to ensure long-term food security and ecosystem health.
