Combining revealed and stated preference methods to assess the private value of agrobiodiversity in Hungarian home gardens
Provedor de dados: 31
Autores: Birol,   Ekin; Kontoleon,   Andreas; Smale,   Melinda.
Hungarian home gardens are small-scale farms managed by farm households using traditional management practices and family labor. They generate private benefits for farmers by enhancing diet quality and providing food when costs of transacting in local markets are high. Home gardens also generate public benefits for society by supporting long-term productivity advances in agriculture. In this paper, we estimate the private value to farmers of agrobiodiversity in home gardens. Building on the approach presented in EPTD Discussion Paper 117 (2004), we combine a stated preference approach (a choice experiment model) and a revealed preference approach (a discrete-choice, farm household model). Both models are based on random utility theory. To combine the...

SUSTAINABLE USE AND MANAGEMENT OF CROP GENETIC RESOURCES: LANDRACES ON HUNGARIAN SMALL FARMS

Crop genetic resources are natural assets that are necessary for future crop improvement. In isolated, marginal production environments where markets function imperfectly, farm families depend on them directly for food. In recognition of their importance, international agreements such as the Convention on Biological Diversity and the International Treaty on Plant Genetic Resources for Food and Agriculture encourage national governments to support their sustainable use and management, on farms and in gene bank collections. Hungary is a signatory to these international agreements. The aim of this study is to contribute research-based information to support the design of efficient and equitable conservation programmes for socially valuable crop landraces...

Modeling Price Response of Farm Households Under Imperfect Labor Markets: A Farm Household Approach to Family Farms in Poland
Provedor de dados: 31
Autores: Henning,   Christian H.C.A.; Henningsen,   Arne.
In the paper a flexible FHM approach is estimated to model price responses of farm households under imperfect labor markets. In contrast to former studies the model explicitly incorporates simultaneously fixed and variable transaction costs as well as heterogeneity. Main results are: (i) In the general approach non-separability not only occurs if households are autarkic, but also when households participate in labor markets. (ii) Under imperfect labor markets, price responses are ambiguous and differ for the non-separable and separable model. However, econometric analysis indicates only moderate differences between the two models except for crop production for which an inverse supply response is estimated.

Household Behavior Under Market Failures: How Natural Resource Management in Agriculture Promotes Livestock Production in the Sahel
Provedor de dados: 31
Autores: Dutilly-Diane,   Celine; Sadoulet,   Elisabeth; de Janvry,   Alain.
Improved water harvesting and soil erosion control using the remarkably simple practice of contour stone bunding is shown to increase grain yields by 41% in low rainfall regions of Burkina Faso. Empirical results show that yield increases in food crops help foodbuying farm households import substitute in food consumption, reduce livestock production, and increase seasonal migration which is more compatible with seasonal agriculture than with the yearlong livestock activity. Self-sufficient households, by contrast, can take advantage of higher yields to free resources from food production and allocate these to expand their livestock economy, thus benefiting more from the region's comparative advantage. We also show that greater effectiveness in cooperation...
