    Urban and peri-urban agriculture, the dairy farms of Cairo, Egypt
    Daburon, Annabelle ; Alary, Véronique ; Ali, Ahmed ; El-Srogi, Mohammad ; Tourrand, Jean François - \ 2019
    In: Diversity of Family Farming Around the World / Bosc, P.M., Sourisseau, J.M., Bonnal, P., Gasselin, P., Valette, E., Springer Netherlands - ISBN 9789402416169 - p. 29 - 42.
    The megalopolis that is Cairo now has a population of nearly 20 million inhabitants. Within the city and on its periphery are family farms engaged in various types of agricultural activity. This chapter sheds light on the functioning of these farms, which contribute to Cairo’s food supply, especially as regards dairy and market gardening products. The data used are from a study on milk supply in Cairo conducted as part of the Dairy project undertaken jointly by CIRAD, Ain Shams University and the Animal Production Research Institute (APRI).
    A discussion support model for a regional dairy-pasture system with an example from Reunion island

    Reunion Island, situated in the Indian Ocean, presents a unique case study for modelling regional bio-economic parameters of the dairy industry. It is a good example of a closed system for several parameters of the model such as movement of animals, labour, consumption and available land. The existence of several agro-ecological zones from tropical to temperate, and various different types of terrain and vegetation presents another unique opportunity to study the impact of these features on the dairy industry. The present study models the dairy sector at a regional (island) level to study the impact of new or adapted agricultural policies in relation to changes in subsidy levels, price fluctuations and environmental policies (mainly nitrogen management). The model can be used to generate a number of scenarios to explore the effects of various policy measures, such as fixing the stocking rate according to EU norms, increasing or decreasing the milk subsidy, intensification (such as an increase in milk production to the allotted quota of 40 million litres/yr) and varying labour/price constraints (such as a reduction in labour hours or an increase or decrease in the milk price). The model is being utilized by the local dairy cooperative as a discussion support tool to study the implications at the regional scale of expanding the sector and assessing its economic, environmental and social impact

    data envelopment analysis - dairy farming systems - technical efficiency - nonparametric approach - bangladesh - frontier
    This paper aims to analyze efficiency on dairy farms in Reunion Island, a French overseas district located in the Indian Ocean. On this island, dairy farming is promoted with financial and technical support from the European Union, with the French and local governments aiming at reducing dependency on imports of milk powder and dairy products and creating employment. A critical factor for increasing the local milk production is the limited availability of arable land because of the small size and the volcanic nature of the island. In this paper, we study the efficiency levels of dairy production on 34 farms by using a data envelopment analysis approach. The average technical efficiency score of farms, assuming constant returns to scale, was 0.927, with 19 out of 34 farms not being efficient. The technical efficiency with a variable returns to scale specification was 0.951. The efficiency with which farmers used their land (subvector efficiencies) was estimated in a second model. The average subvector efficiencies calculated with constant returns to scale and variable returns to scale models were lower than the technical efficiencies. The farmers on the efficiency frontier had a relatively higher milk production, milk production per cow, and land surface than those who were less efficient. A policy promoting better use of the land on inefficient farms should increase the milk production-to-land ratio. Possible on-farm strategies are improved feeding systems, farms having their own heifer breeding, and improved genetics.
