EAERE Conference 2009 Amsterdam
Food, Feed, Fuel and Fiber Session at EAERE
In the first presentation, Etti Maria Winter from the University of Hannover analyzed alternative management options for forest ecosystems in Sub-Saharan Africa by means of a village model. Her outcomes emphasize the importance of proper forest management for the incomes of the rural poor, but also the need for additional sources of energy in order to guarantee sustainability of these resources.

In the second contribution, Michael Roberts of North Carolina State University assessed the effects of the US ethanol policy on international prices on the basis of a world supply and demand model for edible calories, taking into account weather-induced yield fluctuations. According to his assessment, 30% of the 2008 global food price hikes can be attributed to the US policy of mandatory blending of bio-ethanol. The full text can be found here.
On behalf of the CATSEI-team, SOW-VU’s counterpart Huanguang Qiu (Center for Chinese Agricultural Policy, Beijing) gave a presentation on ‘Biofuel use and agricultural intensification in China’. In this paper, the Chinagro model is used to analyze China’s plans to produce 10 million tons of bio-ethanol by 2020 on the basis of the feedstocks sorghum, cassava, sweet potato and maize.

The final contribution was by Roelf Voortman who presented ‘Nutrient shortages and agricultural recycling options worldwide, with special reference to China’. This paper expresses serious concerns about looming nutrient shortages in the world and discusses, against this background, the often inefficient application of fertilizers in agriculture. At the end of the paper, these trends are illustrated by means of Chinagro outcomes of net surpluses of N, P and K throughout China. The full text of this paper can be found here.
