During the last years, the renewable energy strategy of the European Union (EU) and the proposed policies and regulations, namely the Renewable Energy Directive (RED), have been heavily discussed among scientific circles and various interest groups. The sustainability of different biofuels and...

Motivated by the conclusions from various modelling studies, modifications to the bioenergy sector regulations are under way in Europe and in the USA to account for emissions from indirect land-use change (ILUC). Despite their influence on the policy-making, evaluations of the capacity of...

Indigenous fruits contribute widely to rural incomes in Southern Africa but their availability is declining. A domestication program aims to increase farm-household income and conserve biodiversity through farmer-led tree planting. Planting domesticated indigenous fruit trees is an uncertain,...

Malmquist total factor productivity (TFP) index has been extensively applied in the literature to measure productivity growth decomposition. This study applies a parametric decomposition of a Generalized Malmquist TFP index to measure and compare the levels and trends in agricultural...

Economic reform in China helped transform the structure and volume of agricultural production and resulted in significant changes in efficiency and productivity. This paper measures agricultural technical efficiency (TE) and total factor productivity (TFP) in China by allowing producers...

Ziel dieser Studie über die Verflechtung der Ferkelversorgung ist es zum einen quantitativ darzustellen, welche Bedeutung interregionale und internationale Ferkellieferungen für die Schweinemast in Deutschland haben. Zum anderen sollen durch einen Vergleich der Produktionskosten und ihrer...

Dieser Arbeitsbericht analysiert die Stoffströme des deutschen Biokraftstoffsektors für das Jahr 2007. Zahlreiche Statistiken wurden ausgewertet, um prozentuale Aussagen treffen zu können wie viel Rohstoffe in die Biokraftstoffproduktion und weitere energetische Verwendungen floss im...

Prior research shows long-run productivity growth in agriculture is associated with increases in the stock of public scientific knowledge and private patented inventions. However, private inventions may be a function of the stock of public knowledge. In this paper, we examine the possibility...

We show that much of Africa s recent growth and poverty reduction can be traced to a substantive decline in the share of the labor force engaged in agriculture. This decline has been accompanied by a systematic increase in the productivity of the labor force, as it has moved from low...
