1. Biofuels and food prices: Separating wheat from chaff

Author:
Wallace E. Tyner
Source:
Global food security 2013 v.2 no.2 pp. 126-130
ISSN:
2211-9124
Subject:
bioenergy industry; biofuels; chaff; commodity prices; corn; developed countries; developing countries; farmers; food prices; food security; macroeconomics; markets; supply balance; trade policy; wheat; Brazil; Europe; United States
Abstract:
... Biofuels are produced from agricultural commodities, so they represent a competing demand for those commodities. Therefore, it is clear that biofuels have some impact on agricultural commodity prices, so the food–fuel debate surrounds the relative contribution of biofuels to agricultural commodity price increases compared with other drivers. In this paper we have argued that there are many causes ...

2. Biofuels in Brazil: Evolution, achievements and perspectives on food security

Author:

Global food security 2013 v.2 no.2 pp. 117-125
ISSN:

Subject:
biodiesel; cattle breeding; commodity prices; cultivation area; energy costs; ethanol; ethanol production; food security; gasoline; liquids; road transportation; Brazil
Abstract:
... Liquid biofuels, as ethanol and biodiesel, supply 25% of the road transport fuel consumed in Brazil. Ethanol blending has been mandatory since 1931, pure ethanol has been used since 1975, and nowadays flex-fuel cars are widely used. In 2008, ethanol production reached 28Mm³, but recently, government efforts to reduce gasoline prices have reduced the demand for ethanol. In turn, biodiesel blending ...

3. How biofuels policies affect the level of grains and oilseed prices: Theory, models and evidence

Author:

Global food security 2013 v.2 no.2 pp. 82-88
ISSN:

Subject:
biofuels; commodity prices; corn; developing countries; energy policy; food grains; food security; fuel production; markets; models; oilseeds; rice; time series analysis; wheat
Abstract:
... This paper synthesizes and critiques three approaches to the analysis of the recent booms in food grains and oilseeds commodity prices: the ‘perfect storm’; statistical time-series models; and models explaining how biofuels linked the fuel and agricultural markets, thus giving rise to a new era of commodity prices. We find that biofuel policies and corn markets were a key instigator of the sharp f ...

4. Managing food price instability: Critical assessment of the dominant doctrine

Author:
Franck Galtier

Global food security 2013 v.2 no.2 pp. 72-81
ISSN:
2211-9124
Subject:
developing countries; farmers; food prices; food security; grains; macroeconomics; politics; world markets
Abstract:
... Ever since the late 1980s, the management of agricultural price instability has been dominated both in academic and political circles by a single doctrine. Its domination is so strong that almost all research on this topic has since been abandoned. Based on a very extensive review of the theoretical and empirical literature, this paper provides a critical assessment of this doctrine as applied to ...

5. Second generation biofuels and food crops: Co-products or competitors?

Author:
Wyatt Thompson; Seth Meyer

Subject:
agricultural land; biofuels; biomass; coproducts; corn stover; crop production; econometric models; feed prices; feedstocks; food crops; food prices; food security; issues and policy; markets; warm season grasses; wheat straw; United States
Abstract:
... Stylized experiments of an economic model show that second generation biofuels can hurt or help food security. Impacts depend critically on whether the feedstock competes with traditional crops or is a co-product in their production. Dedicated biomass, like warm season grasses, likely competes at least somewhat with food crop production. To the extent that agricultural land is allocated to dedicat ...

6. Is body mass index an appropriate proxy for body fat in children?

Subject:
World Health Organization; adiposity; body mass index; childhood obesity; children; epidemiological studies; food security; income; malnutrition
Abstract:
... As the global prevalence of childhood overweight and obesity spreads to low and middle income countries, there is an increasing need for researchers to assess overweight and obesity in populations where child undernutrition still prevails. Although BMI (body mass index) cutoffs are widely used in research and project evaluations, they have only recently been included in WHO definitions for overwei ...

7. Market-mediated environmental impacts of biofuels

Author:

Global food security 2013 v.2 no.2 pp. 131-137
ISSN:
2211-9124
Subject:
biofuels; crop prices; environmental impact; feedstocks; food security; greenhouse gas emissions; land cover; land use change; markets; models; surveys; uncertainty
Abstract:
... This paper surveys the evidence on market-mediated environmental impacts of biofuels, with special attention to the indirect greenhouse gas emissions stemming from land cover change in the wake of increased demand for biofuel feedstocks. We find clear evidence that market mediated land use response to crop price changes has occurred over the past decade. However, despite all the research that has ...

8. The crisis in food price data

Author:
John Gibson

Global food security 2013 v.2 no.2 pp. 97-103
ISSN:
2211-9124
Subject:
developing countries; food prices; food quality; food security; foods; household surveys; nutrients
Abstract:
... Many studies estimate impacts of higher food prices on consumer welfare. Yet reliable data on real welfare levels in poor countries are rare since surveys prioritize collecting nominal living standards data over price data. Narrower questions about the impacts of prices on food quantity consumed and on the availability of nutrients are poorly answered. Most studies ignore coping responses that inv ...

9. A framework for analyzing the interplay among food, fuels, and biofuels

Author:
John Baffes

Global food security 2013 v.2 no.2 pp. 110-116
ISSN:
2211-9124
Subject:
arable soils; biofuels; commodity prices; energy content; energy costs; food crops; food prices; food security; issues and policy; petroleum
Abstract:
... This paper provides a framework for analyzing the complex relationship among food, fuels, and biofuels. It first notes that high energy prices increase the costs of producing food and can induce policies that divert food crops to the production of biofuels. Then, it argues that sustained high crude oil prices, in addition to rendering biofuels profitable, could also induce innovations by increasin ...

Abstract:
... Following a period of increasing oil prices, bioenergy received a wake of renewed attention by policymakers as an alternative renewable energy strategy due to the potential for improving country level energy security, for increasing overall access to energy, stimulating rural development and for curbing greenhouse gas emissions. Nevertheless, concerns about the viability of this strategy and poten ...
