Global food systems are highly inequitable and unsustainable

   Large, persistent gaps exist between developed and developing regions in crop and livestock productivity per hectare/animal, per‑capita income, and value‑added capture — closing these gaps requires raising on‑farm yields, shifting processing to rural areas, and upgrading trade and safety nets. 

• Yield gaps are large: low yields (e.g., Nigeria ~1.55 t/ha) limit farm incomes and the ability to invest in post‑harvest handling and processing. 
• High yields + large processing sectors (USA, Germany, China) translate into higher per‑capita consumption, stronger domestic value‑addition and much larger export value per capita. 
• India’s transition: cereal yields are moderate but per‑capita cereal consumption has been declining as diets diversify — this matters for targeting processing and nutrition policies. 

  Dairy structure differs: developed markets have large, concentrated herds and industrial processing; many developing countries have fragmented herds and weak collection/processing, limiting value capture. This goes in line with land holdings size as well due to slow consolidation of land resources in developing regions, as pace of industrial and alternative employment avenues are slower in the initial phases of growth with higher gestation period.

Processed‑food market shares, per‑capita consumption, and export value per capita are heavily skewed toward high‑income regions (EU, North America, East Asia); 

Low‑income regions (Africa, parts of South/Central Asia) show much lower processing shares and export value per capita, reflecting gaps in cold‑chain, processing capacity and retail infrastructure.

• Food systems drive climate risk: Food systems account for ~34% of global GHG emissions (2015 baseline), with production, land‑use and distribution all material contributors—so sustainable food systems are climate mitigation levers. 
• Climate threatens yields and livelihoods: Meta‑analyses project large crop declines under high‑emissions scenarios (e.g., maize −22%, rice −9%, wheat −14%  by 2080–2100 under SSP5‑8.5), risking calorie supply and farm incomes without adaptation

• Food loss and waste erode food security and emissions goals: ~14% of food is lost post‑harvest and ~17% wasted at retail/consumer levels, representing large inefficiencies and 8–10% of global GHGs tied to uneaten food. Reducing FLW raises availability and farmer incomes while cutting emissions. 

•  Close yield gaps — targeted R&D, extension, input access and irrigation to raise t/ha where yields are low.
• Aggregation and land‑leasing to raise farm scale economics; 
• Scale climate‑smart seeds and water‑efficient irrigation plus targeted insurance for smallholders. 
• Prioritise investments in dairy collection, cold chain, rural processing, and market access to link smallholders and capture value and cut post‑harvest loss. 
• Scale rural processing & cold chains — shared infrastructure lowers unit costs and raises the share of value captured locally.
• SME finance + standards — credit, technical assistance and quality labs to help small processors meet export/retail requirements.
• Targeted finance and cooperative strengthening to raise incomes and resilience. 
• Trade + industrial policy alignment — use export promotion to build processing clusters while protecting nascent domestic firms.
• Nutrition safeguards — promote fortified, minimally processed options for low‑income consumers.
• Integrate mitigation into food policy (methane reduction, reduced deforestation, efficient refrigeration). 
• Promote off‑farm rural employment and agro‑industrial clusters to raise incomes and reduce vulnerability.
