The objective of this paper is to evaluate the indirect impacts of a set-aside policy on the environment through crop intensification. We estimate a structural, multi-output model on a panel of French farmers from 2006 to 2010, accounting for multivariate selection (corner solutions) on crops and land use. We use a parametric and a semi-nonparametr...
Chapter
Econometric land use models study determinants of land use shares of different classes: “agriculture”, “forest”, “urban” and “other” for example. Land use shares have a compositional nature as well as an important spatial dimension. We compare two compositional regression models with a spatial autoregressive nature in the framework of land use. We...

Interaction between mitigation and adaptation is a key question for the design of climate policies. In this paper, we study how land use adaptation to climate change impacts land use competition in the agriculture, forest and other land use (AFOLU) sector and how a mitigation policy in agriculture might affect this competition. We use for this purp...

The objective of this paper is to compare the predictive accuracy of individual and aggregated econometric models of land-use choices. We argue that modeling spatial autocorrelation is a comparative advantage of aggregated models due to the smaller number of observation and the linearity of the outcome. The question is whether modeling spatial auto...

Agricultural rent in land-use models: comparison of frequently used proxies. Spatial Economic Analysis. This paper compares the performance of econometric land-use models based on three proxies for agricultural land rent: farmers’ revenues, land prices and shadow land prices derived from a mathematical programming model. We consider different land-...
Article
In this paper, we propose models that allow to predict land use (urban, agriculture, forests, natural grasslands and soil) at the points of the Teruti-Lucas survey from easily accessible covariates. Our approach involves two steps: first we model land use at the Teruti-Lucas point level and second, we propose a method to aggregate land use on regul...
Article
World crop prices increased dramatically during the period 2006-2009. In this context of high crop prices, farmers may tend to increase the amount of agro-chemical inputs they use in order to increase yield and manage risks related to crop production. These practices could, however, have potentially adverse environmental effects in terms of loss of...
Article
We consider the problem of land use prediction at different spatial scales using point level data such as the Teruti-Lucas (T-L hereafter¹ survey and some explanatory variables. We analyze the components of the prediction error using a synthetic data set constructed from the Teruti-Lucas points in the Midi-Pyrénées region and a five categories land...

In this study, we use an individual panel data approach to measure the indirect effect of biofuel policies in France. Our model tests the hypothesis that an increase in rapeseed prices increases pesticide demand, rapeseed being the principal feedstock for the production of biodiesel in France. We take the case of farms observed from 1993 to 2006 in...

To both increase yield and cope with risks related to crop production, farmers increase the amount of chemical fertilizers and pesticides they use. These practices have negative effects on the environment, in terms of losses in biodiversity as well as increases in water and air pollution. They may also be responsible for numerous human health probl...

Very few scientific studies have focused on the determinants of households’ livelihoods’ strategies in the Congo Basin. The aim of this paper is to understand which factors drive the choice of portfolio activities in rural regions. More precisely, the role of human, financial, natural and location assets in the portfolio choice is investigated. A unique dataset is used from our recent survey with 1035 random and stratified households in 108 villages of the Tridom landscape to investigate household preferences between (1) specialization and diversification strategies, (2) land-conversion and non-land-conversion activities, and (3) between strategies relying on forest vs other strategies. Our results show significant similarities on the likelihood of households living in the same neighborhood to prefer a given livelihoods strategy. Beside socioeconomic characteristics, the existence of human-wildlife conflict, as well as the indigenousness, directly lead household’s heads to make the choice of diversified strategies, or to choose activities related to land-conversion. These choices lead to some significant spillover effects on the likelihood of neighboring household’s heads to adopt the same strategies. keywords : Forest-based livelihoods, Agriculture and cash crop, Diversification strategies, Deforestation, Spatial Spillover Effects, Spatial Autoregressive Probit.
