Biofuel policies and the environment: the effects of biofuel feedstock production on climate, water quality and biodiversity

Lankoski, Jussi E.; Ollikainen, Markku - International Association of Agricultural Economists - IAAE - 2009

In this paper we examine the multiple environmental effects of policies promoting biofuel production from agricultural crops. We develop theoretical and empirical frameworks and provide an integrated economic and ecological modelling approach: an economic model of farmers’ decision making is...

Regional differences in the determinants for structural change in German agriculture

Roeder, Norbert; Kilian, Stefan - International Association of Agricultural Economists - IAAE - 2009

In Germany agricultural land use is very heterogeneous with respect to management orientation and productivity even at local level. Also the rate of structural change shows a wide variation. While for a limited number of factors (e.g. farm size) a stable relation to structural change could be...

From Pasture Land to Farm Plots, Triggers and Motivations for Land Use Changes in Afar, Ethiopia

Kotu, Bekele Hundie - International Association of Agricultural Economists - IAAE - 2009

Communal land use system has existed in pastoral Afar (as in many other pastoral areas) since time of immemorial accommodating the interests of different user groups. This form of land use system, which has adapted to the harsh environment in which herders raise their livestock, enables...

Investigation of the factors influencing adoption of GM crops at country level

Hall, Clare; Toma, Luiza; Moran, Dominic - International Association of Agricultural Economists - IAAE - 2009

With the possible exception of nuclear technology, few scientific breakthroughs have generated the level of emotive debate that has surrounded the roll-out of agricultural biotechnology. Initial discussion about the environmental impacts of agricultural genetic modification, are now frequently...

Spatially-explicit scenarios on global cropland expansion and available forest land in an integrated modelling framework

Krause, Michael; Lotze-Campen, Hermann; Popp, Alexander - International Association of Agricultural Economists - IAAE - 2009

The pressure on land as required input in competing uses fuelled research on trade-offs in land use due to agricultural land expansion to meet food demand which is explicitly and implicitly treated in global land use modelling. Global land use studies rely on assessing the trade-offs by assuming...

Land Constraints in Kenya’s Densely Populated Rural Areas: Implications for Food Policy and Institutional Reform

Jayne, Thomas S.; Muyanga, Milu - Agricultural Economics Society - AES - 2012

This study analyzes the impact of increasing population density in Kenya’s rural areas on smallholder behavior and welfare indicators. We first present evidence to explain how land constraints can be emerging within an overall context of apparent land under-utilization. Using data from five...

Effects of Water Priority Policy on Farmers' Decision on Acreage Allocation in Northwest China

Zhang, Lei; Herzfeld, Thomas - International Association of Agricultural Economists - IAAE - 2012

This article analyses the impact of a water allocation priority policy for a specific crop on farmers’ acreage allocation to different crops. To accomplish this, a system of crop acreage demands conditional on output yields, prices of variable inputs and levels of quasi-fixed inputs is...
