• UN FAO (2009) “How to Feed the World in 2050”
• The current global population of 7.3 billion habitants is anticipated to increase to 9.7
billion by 2050, which means 60% more food will be needed.
• Climate change is expected to have a
significant and negative impact on agriculture and fisheries, affecting global food production.

• UN “World Water Development Report 2012”
• The world’s natural resources are under stress by degradation
• The amount of arable land will increase by less than 5%.

• UN ESCAP (2013)
Rapid urbanization has emerged in Asia-Pacific Since 1990.
More than half of the world’s mega-cities (13 out of 22) are now found in Asia-Pacific
Economic growth in the Asia-Pacific region is led by cities
• Internal migration is the main factor behind urban growth
• Over 40% of the Asian-Pacific population which lives in cities contributes 80% of the region’s GDP.

17| Methodology
Estimating the economic impact of food loss/waste ratio changes in APEC region and in Taiwan, in
particular, requires a solid computational core.
To achieve this goal, we use Computable General Equilibrium (CGE) model with water and energy modules to bring into focus the economy-wide assessment of reducing food loss and wastes.
CGE model is a multi-sectoral model based on neo- classical economic theory and national input-output table.

• In view of the fact that 40% of all foods require
refrigeration, 15% of world fossil fuel energy is used in food transport refrigeration.
• Preserving food is prevalent as most households engage in these practices through refrigeration system.
• Energy consumption in cold chains has been predicted to rise significantly
• Of critical attention is the increasing number of road
transport refrigeration which is highly gaining enormous ground globally.

38| The GTAP Model
• The GTAP model is an effort to map the intricacies and
interconnectedness of the global economy mathematically.
• GTAP9 data set, the version used for this analysis, encompasses:
• 140 countries and regions
• 57 industries
• 8 factors of production
Furthermore, the model allows for the interplay between households, industries, and the overall economy.

• GTAP-E Data Base –
• Provides carbon dioxide (CO2) emissions data distinguished by fuel and by user for each of the 140 countries/regions in the GTAP 9 Data Base.
• GTAP Non-CO2 Emissions Data Base –
• Provides information on other Greenhouse gas (GHG) emissions such as Methane (CH4), Nitrous Oxide (N2O), Fluorinated gas (FGAS).
• GTAP-Power Data Base –
• An electricity-detailed extension including: transmission & distribution, nuclear, coal, gas, oil, hydroelectric, wind, solar, and other power technologies.
• GTAP Land Use Data Base
• Compiled following the agro-ecological zoning approach developed by FAO (2000) and IIASA (2002). Arable land is classified into 18 AEZ based on the length of growing period (LGP) .
• GTAP-Water Data Base
• based on the GTAP version 6 database (Dimaranan 2006) and on the IMPACT 2000 baseline data (Rosegrant et al. 2002).

49| Scenario 1: Uniform
We consider 3 scenarios of food waste reduction:
1. A uniform reduction in food waste ratios by 10% in all APEC members.
The APEC Action Plan for Reducing Food Loss and Waste, 2014 established the goal of a 10% reduction in food loss and waste by 2020 (2012 base).
In this scenario we focus on food waste ratios and reduce them uniformly by 10% in distribution (retail) and
consumption (consumers) for all APEC economies.

50| Scenario 2: Non-Uniform
2. A targeted food loss/waste reduction
In this scenario we apply a food loss or waste reduction at the stage of highest loss for each region.
• Supply: Production, Handling & Storage, Processing &
Packaging
• Demand: Distribution, Consumption

3. An ambitious targeted food loss/waste reduction
We chose 20% as an ambitious, yet feasible, level of food waste and loss reduction.
