| The US Environmental Protection Agency announced a waiver allowing an increase in the Fuel-Ethanol blend limit (the “blend wall” ) from 10% (E10) to 15% (E15) on October,2010.Justifications for the waiver are reduced vehicle fuel prices and less consumption of petroleum gasoline, leading to energy security. In this paper, employing Monte Carlo simulations and Savitzky-Golay smoothing filter, an empirical study examines this waiver revealing an anomaly where a relaxation of this blend wall elicits a demand response. Under a wide range of elasticities, this demand response can actually increase the consumption of petroleum gasoline and thus lead to greater energy insecurity. The economics supporting this result and associated policy implications are... |

| The Intergovernmental Panel on Climate Change (IPCC) has identified a number of soil-management strategies that can be implemented to reduce GHG emissions. However, before deciding which of these strategies are most appropriate in any given situation, it is important to investigate how these strategies affect other aspects of sustainable development. For instance, some attempts to sequester carbon in the landscape could alter the soil’s capacity to filter water. Alternatively, other strategies could unintentionally increase net energy consumption through greater fertilizer use. Focusing specifically on opportunities to implement soil-management strategies in the European Union (EU), we discuss the synergies and trade-offs of those strategies with... |

| This paper focuses on global responsibility of food, energy and environmental security. World population growth will lead to increasing demand for food and feed with increasing meat consumption. With globalization and urbanization production is moving to the most competitive countries and regions, and food trade is becoming more liberalized but also more concentrated. Growing energy demand and climate change will also influence food production. Additional challenges are increasing market volatility resulting from yield and climate change. We need greater responsibility in cutting greenhouse gas (GHG) emissions, in showing greater respect for the environment. More responsibility is needed regarding food and energy security, and environmental sustainability.... |

| Az élelmiszerárak növekedése 2006–2008 között a világ egyes térségeiben zavargásokhoz és a politikai stabilitás megrendüléséhez vezetett. Különösen fejlődő országokban súlyos a helyzet, ahol a legszegényebb rétegek jövedelmük döntő hányadát élelmiszerekre költik. Az agrárpiacokon a kereslet vált meghatározóvá, mennyiségi (humáncélú és ipari felhasználás rohamos növekedése) és minőségi értelemben (élelmiszer-fogyasztás szerkezetének változása). Árkilengések persze korábban is előfordultak, de a 2007/2008-as gazdasági évben tapasztalt ársokkot számos tényező együttesen idézte elő, első helyen a világ gabona- és olajosmag-készleteinek megcsappanása. Az élelmezésbiztonságban fontos a fizikai kínálat, mert az emberek rettegnek attól, hogy nem jutnak élelemhez,... |
