A Structural Land-Use Analysis of Agricultural Adaptation to Climate Change: A Proactive Approach AgEcon
Kaminski, Jonathan; Kan, Iddo; Fleischer, Aliza.
This article proposes a proactive approach for analyzing agricultural adaptation to climate change based on a structural land-use model wherein farmers maximize profit by allocating their land between crop-technology bundles. The profitability of the bundles is a function of four technological attributes via which climate variables‟ effect is channeled: yield potential; input requirements; yields' sensitivity to input use; and farm-level management costs. Proactive adaptation measures are derived by identifying the technological attributes via which climate variables reduce overall agricultural profitability, despite adaptation by land reallocation among bundles. By applying the model to Israel, we find that long-term losses stem from yield potential...

Climate-related land use policies in Brazil: how much has been achieved with economic incentives in agriculture? Repositório Alice
CARAUTA, M.; TROOST, C.; GUZMAN-BUSTAMANTE, I.; HAMPF, A.; LIBERA, A.; MEURER, K; BONECK, E.; FRANKO, U.; RODRIGUES, R. de A. R.; BERGER, T..
Until 2019, the Brazilian federal government employed a number of policy measures to fulfill the pledge of reducing greenhouse gas emissions from land use change and agriculture. While its forest law enforcement strategy was partially successful in combating illegal deforestation, the effectiveness of positive incentive measures in agriculture has been less clear. The reason is that emissions reduction from market-based incentives such as the Brazilian Low-Carbon Agriculture Plan cannot be easily verified with current remote sensing monitoring approaches. Farmers have adopted a large variety of integrated land-use systems of crop, livestock and forestry with highly diverse per-hectare carbon balances. Their responses to policy incentives were largely...

Do farmers provide agri-environmental services efficiently? – An economic analysis AgEcon
Kantelhardt, Jochen; Eckstein, Karin.
Agricultural land use does not only concern farmers, but also has a large number of social and environmental effects. Consequently, it is to be assumed that farmers have to use financial resources as well as labour in order to provide these services. Using the nonparametric method of Data Envelopment Analysis (DEA), we calculated the economic as well as the ecological efficiencies of farms and examined whether farms are able to succeed in combining ecological and economic efficiency. In addition to this analysis, we studied the driving factors of the respective efficiencies. The study was carried out in four typical production regions in Bavaria which vary in their proportions of grassland as well as their yield potential; thus, the study regions reflect a...

DYNAMICS OF CHANGES IN AGRICULTURAL LAND USE ARISING FROM CLIMATE, POLICY AND SOCIO-ECONOMIC PRESSURES IN EUROPE AgEcon
Fekete-Farkas, Maria; Singh, Mahesh Kumar; Rounsevell, Mark; Audsley, Eric.
This article analyses the mechanism behind the changes in agricultural land use arising from climate variables, agricultural policies and socio-economic pressures. The study presented here has undertaken an integrated methodology in the estimation of future land use change in Europe. The scenarios constructed in this study include estimates not only of changes in the climate baseline, but also of possible future changes in socio-economics. The overall aim of the study was to raise the awareness of policy makers about the vulnerability of the European rural economy and agro-ecosystems based on economic and environmental considerations in term of both their sensitivity and capacity to adapt to change.

Environmental Amenities and Optimal Agricultural Land Use: The Case of Israel AgEcon
Kan, Iddo; Haim, David; Rapaport-Rom, Mickey; Shechter, Mordechai.
This paper evaluates the effectiveness of changing land allocation among crops as a mechanism for increasing social welfare, where production profits and amenity benefits are augmented. A positive mathematical programming model is calibrated and applied to the northern part of Israel, using a crop-discriminating amenity-benefits function. Changes in land allocation increase social welfare by 2.4% nationwide, and by up to 15% on the regional level. Regional scale farming-profit losses amount to up to 6%. Due to the decreasing-return-to-scale nature of the amenity-benefits function, the inter-regional variability appears sensitive to the manner in which the country is divided into regions.

OPTIMAL AGRICULTURAL LAND PRICING POLICIES UNDER MULTIPLE EXTERNALITIES IN A GLOBAL ECONOMY AgEcon
Peterson, Jeffrey M..
Agriculture has recently been noted as a provider of non-market environmental benefits in addition to its traditional recognition as a source of negative externalities from polluting inputs. In this paper, a general equilibrium framework is used to determine optimal land subsidies and input taxes in agriculture. When agriculture generates both amenities and pollution, the optimal subsidy does not equal the net extra-market value of agricultural land. If opened to international trade, a small economy will fully correct externalities, while large economies have an incentive to set policies at non-internalizing levels to exploit terms-of-trade effects.

Socio-economic Scenarios of Agricultural Land Use Change in Central and Eastern European Countries AgEcon
Fekete-Farkas, Maria; Rounsevell, Mark; Audsley, Eric.
The study presented in this paper is part of the ACCELERATES (Assessing Climate Change Effects on Land Use and Ecosystems from Regional Analysis to The European Scale) project whose main goal is the construction of integrated predictions of future land use in Europe. The scenarios constructed in the project include estimates not only due to changes in the climate baseline, but also estimates due to possible future changes in socio-economics. The overall aim of the ACCELERATES was to assess the vulnerability of European agroecosystems based on economic and environmental considerations in term of both their sensitivity and capacity to adapt changes. The historical background, the type of economy, the policy aim and governance and importance of agriculture in...

The influence of climate change, technological progress and political change on agricultural land use: calculated scenarios for the Upper Danube catchment area AgEcon
Henseler, Martin; Wirsig, Alexander; Krimly, Tatjana; Dabbert, Stephan.
Both climate and agricultural policy changes are commonly seen as important drivers for agricultural production. In this study, scenarios of climate and political change were calculated for the Upper Danube catchment area using the regional optimization model ACRE. Two political scenarios were calculated for the year 2020. One scenario assumes the continuation of the Common Agricultural Policy reform 2003 the other assumes a strong shift away from payments of the first pillar to payments of the second pillar of the CAP. Both scenarios were combined with four different scenarios of climate change and technological progress derived from ICCP SRES assumptions and the ACCELERATES project. The results of the scenario calculations were analysed with respect to...

The Provision of Ecosystem Services by Agriculture – a Spatially Explicit DEA Approach AgEcon
Kapfer, Martin; Hübner, Rico; Eckstein, Karin; Ziesel, Sigrid; Kantelhardt, Jochen.
According to the concept of ecosystem services, agriculture not only provides commodities but also cultural and regulating services. While it is easy to value commodity production by market prices, the valuation of cultural and regulating services is complex because of their public good character. Non-parametric approaches such as the Data Envelopment Analysis (DEA) allow for estimating the contribution of agriculture to such services. However, it is not enough to know the extent of ecosystem services provided; it is also necessary to be aware of which farmers provide these services and where they are provided. In this paper, we suggest a plot-specific approach combining GIS analysis and DEA models. This allows a spatially explicit assessment of...
