Cím:	Biofuel use : peculiarities and implications / József Popp, Sebastian Kot, Zoltán Lakner, Judit Oláh

Megjegyzések:	Transport biofuels are currently the fastest growing bioenergy sectors even they represent around 3-4% of total road transport fuel and only 6% of total bioenergy consumption today. Low oil prices and poor margins continue to challenge biofuel producers in Europe. Under current market conditions it is unlikely that the 7% cap will be reached in the EU by 2020. Since the past ten years, production of biodiesel from waste and animal fats has taken off, while the commercialization of cellulosic ethanol is lagging behind compared to former targets. Co-products are supposed to be credited with the area of cropland required to produce the amount of feed they substitute. If co-products are taken into account, the net use of land and feedstocks declines. Most existing biofuel regulations significantly undervalue the contribution of co-products when assessing the net land use and GHG impacts of biofuel production. Long-term transport shares are the most challenging to project because the range of possible vehicle technologies and fuel types in the future is very broad and future oil prices are uncertain. It is concluded that the rise in the use of biofuels has slowed down and sustainability criteria have been established regarding the use of land and the mitigation of environmental impacts caused by biofuel production.

Cím:	Social network analysis of scientific articles published by food policy / József Popp, Péter Balogh, Judit Oláh, Sebastian Kot, Mónika Harangi Rákos, Péter Lengyel
Dátum:	2018
ISSN:	2071-1050
Megjegyzések:	The article analyses co-authorship and co-citation networks in Food Policy, which is the most important agricultural policy journal in the field of agricultural economics. The paper highlights the principal researchers in this field together with their authorship and citation networks on the basis of 714 articles written between 2006 and 2015. Results suggest that the majority of the articles were written by a small number of researchers, indicating that groups and central authors play an important role in scientific advances. It also turns out that the number of articles and the central role played in the network are not related, contrary to expectations. Results also suggest that groups cite themselves more often than average, thereby boosting the scientific advancement of their own members.
