Straining the links between biofuel policies and food insecurity in developing countries Wyatt Thompson and Ignacio Pérez Domínguez 17th ICABR Conference, 19th June 2013, Ravello (Italy)
Introduction • Fuel versus food debate: • concern about the agricultural commodities used for biofuel production causing food insecurity in developing countries • one-for-one as the extreme case • Need for a more nuanced view: • Biofuel expansion not only driven by policies but also by price increases of crude oil • Domestic and international markets have different links price elasticities have a relevant effect • This paper tries to decompose the link between a biofuel policy in a developed country (US) and food use in a group of developing countries (Africa and Asia least developed) OECD Trade and Agriculture Directorate
Steps from a biofuel demand shock in a DVD country to food use in DVG’s Reduction in corn imports (developing) Increase in US corn use for ethanol Increase in US biofuel mandate (scenario shock) Reduction in corn use for food (developing) Reduction in corn exports (US) OECD Trade and Agriculture Directorate
Methods and Data: Aglink-Cosimo Model • Partial equilibrium model: agriculture, fish/seafood and biofuels • Co-developed by the OECD (Aglink) and the FAO (Cosimo) • Net trade model for representative commodities, world coverage • Model release linked to the yearly OECD-FAO publication on medium-term projections for agricultural markets (2013-2022 last week in Beijing) • Data coming from experts (country questionnaires and FAO databases) • Detailed biofuel module for the major producers: US, EU, Brazil (see next presentation) OECD Trade and Agriculture Directorate
Baseline projections: coarse grain per capita food use (in 2022, kg/person/year) • High consumption of coarse grains by African and Latin-American countries
Baseline projections: veg. oils per capita food use (in 2022, kg/person/year) • High consumption of vegetable oils by Asian and Latin-American countries
Scenario: a higher fulfillment of the US Renewable Fuel Standard (RFS) • What does this mean? • Higher mandated biofuel blending in the US • Lower than mandated cellulosic production (waiver) mandate waived but not as low as in the baseline, 5 billion additional liters • Implications • Greater demand for conventional biofuel feedstocks in the US: maize for ethanol and vegetable oils for biodiesel • More biofuel production • Higher feedstock prices and less exports from the US • Small effects on developing countries
How to identify the weakest link? • Objective: trace the impacts from biofuel mandate to food use in developing country by identifying the transmission of impacts at each key step • Method: push the shock further along in steps 1) RFS increase only (already seen) 2) #1 + shock on US demand for feedstocks for biofuel 3) #2 + shock on US exports of feedstocks 4) #3 + shock on developing country imports of feedstocks 5) #4 + shock on developing country food use of feedstocks • Intuition: go from estimated impact to automatic 1-for-1 substitution to see differences
Coarse grain and vegetable oils used for biofuel in the USchange from baseline, million metric tonnes
Coarse grain and vegetable oils production in the USchange from baseline, million metric tonnes
Coarse grain and vegetable oils exports from the USchange from baseline, million tonnes
Coarse grain and vegetable oils imports in least developed countrieschange from baseline, million tonnes
Coarse grain and vegetable oils food demand in least developed countrieschange from baseline, million tonnes
Impact ratios Ratio : developing country food use impact / divided by intitial shock in feedstock equivalent Demonstrates: weakness of links after each stage Cases : Ratio = 0 no net effect Ratio = -1 a one-for-one trade off Ratio > 0 cross-commodity effects play a role
Conclusions • The scenarios reveal how expectations of agricultural economists differ from the implicit assumption underlying popular beliefs the impact of a relatively large shock on biofuel demand for coarse grains and vegetable oils by a major producer, such as the US, on food demand in least developed countries is found to be very small. • The impacts are mostly dampened through substitution in trade and domestic markets. • Negative calorie consumption effects in developing countries are present once the shock reaches the importing sector of biofuel feedstock commodities. • Further research needed to expand the exercise to other major biofuel producers and perform sensitivity analysis
