International audience ; The objective of this paper is to study the effect of agricultural policies on marketing decisions as well as the link between marketing and production decisions. We develop an analytical model to study how policies affect marketing decisions and conditions under which the two types of decisions are separable. We found that government policies impact marketing decisions. We also found that the necessary conditions to have separability of decisions are rather restrictive, even in the presence of a perfect hedging tool. We build a stochastic multiperiodic farm model to investigate the empirical relevance of our theoretical findings. The farm model is used to model a representative farm for the Midi-Pyrénées region in France (South-West). The results confirm the impact of price risk and direct payments on both production and marketing decisions with the proportion of grain marketed under different contracts that vary. We also observe that a large supply of marketing contracts allows to stabilize production choices. In particular, market ing contracts can contribute to help farmers to adopt green practices, which are riskier than conventional techniques intensive in chemical inputs.

Der Artikel präsentiert die Ergebnisse einer Fragebogenstudie in der Region Arondizuogu im Imo State in Nigeria, die die Rolle der Geschlechter in der ländlichen Ökonomie (hier der Palmölproduktion) untersuchte. Mit der Einführung effizienterer und energieaufwendigerer Technologien wird ein höherer Einsatz von Männern erforderlich - bisher dominierten Frauen bei der Produktion. Weniger energieaufwendige Verfahren und Kredite für die Bauern, so der Autor, könnten die Probleme lösen. (DÜI-Sbd)

In this article, I provide an analysis of local decision making surrounding crop commercialization in the Kolli Hills, South India. I argue that in the context of changes in the physical environment, cultivating tapioca (cassava) as a cash crop is a conscious decision made by small farmers based on their perceptions of environmental insecurity. Farmers understand market integration as key to coping with external, uncontrollable changes and to fulfilling household and community aspirations. Decisions to cultivate tapioca have contributed to aspects of community development and increasing political agency on the part of villagers.

Untersuchung des Verhältnisses von Cash-Crop-Anbau zur Nahrungsmittelproduktion in Tansanias Landwirtschaft. Unterscheidung von drei Etappen: Priorität der Ernährungssicherung 1919-50; Aufschwung von Cash-Crop-Produktion und genossenschaftlicher Organisation bei positiven Terms of Trade 1950-70; Krise der Nahrungsmittelproduktion und Preisverfall bei Cash Crops 1970-87. Fragen nach inneren und äußeren Ursachen sowie der Rolle des Staates. Erwartung ungleicher Entwicklung und sozialer Differenzierung der Bauern. (DÜI-Wsl)

The objective of this book is to provide information to be used as a basis for evaluating the fragile, shaky structure of global food production. The volume analyses the data by region and by intensity of cultivation; and furnishes information about the yield response, giving some indication of the health of the plants. It will be invaluable to all plant and crop scientists as well as to agriculturalists.
