Eliminating hunger in a world serious about climate mitigation

Area of Science:

• Agricultural Science
• Climate Science
• Food Security Studies

Background:

• Climate change mitigation efforts have historically prioritized energy, industry, and transportation.
• Attention is shifting to hard-to-decarbonize sectors, including food systems.
• Global hunger is rising, exacerbated by climate change impacts on food production.

Purpose of the Study:

• To explore the challenges of achieving net-zero food systems.
• To identify critical policy interventions for food security and climate mitigation.
• To understand the feedback loops between food systems, climate change, and hunger.

Main Methods:

• Analysis of the interconnected dynamics of food production and consumption.
• Review of recent scientific literature on climate change and food security.
• Conceptualization of policy strategies for coordinated adaptation and mitigation.

Main Results:

• Food systems present unique challenges due to moral dimensions of food security.
• Vicious cycles exist: climate change impacts food production, and food shocks can worsen climate change.
• Two key efforts are needed: enhanced smallholder adaptation and "safety valve" institutions.

Conclusions:

• Achieving net-zero food systems is crucial for both hunger elimination and climate stabilization.
• Policy must address the specific dynamics of food production and consumption.
• Coordinated strategies focusing on smallholder farmers and integrated institutions are essential to avoid negative trade-offs.
