Caractéristiques structurelles et écologiques des phytocénoses de sous-bois des plantations privées de teck du département de l’Atlantique (Sud-Bénin, Afrique de l’Ouest)

Abstract Structural and ecological characteristics of private Teak plantations in the Atlantic Department, South Benin, were studied according to the synusial approach of phytosociology in order to contribute to the sustainable management of the plantations. The study of dendrometric characteristics of Teak plantations was done by establishing two temporal plots, each of 1 are. In each plot, the stem girth of the trees and the total height of three mean trees were measured. A total of 99 vegetal synusias has been described, then combined into 18 phytocoenoses. Ecological characteristics are also studied.

Upgrading opportunities in agricultural value chains: Lessons from the analysis of the consumption of processed pineapple products in southern Benin

This study analyzed the consumption of processed pineapple products in southern Benin. The low processing of agricultural products does not enable sub-Saharan Africa to exploit the potential of agriculture for development. The objective of this paper was to identify upgrading opportunities in Benin’s pineapple value chain. A survey was carried out from December 2012 to February 2013 among 250 respondents randomly selected in five cities in southern Benin; and data were collected based on structured interviews. Dried pineapple, jam, syrup, juice, and cocktail were the processed pineapple products available on the market. Beverages, especially the juice, were the main processed pineapple products. The motivations driving the purchase of processed pineapple beverages by consumers were: competitive price and interest in local, natural and therapeutic beverages. The results indicate there is a margin for the value chain to upgrade products and services, and increase the price of pineapple-based products while staying competitive. A strong marketing and advertisement campaign is essential to support wider knowledge of processed pineapple products by consumers. Product traceability is a prerequisite for export in regional and international markets. This makes the certification of the value chain a critical issue. A joint action of value chain stakeholders is needed to exploit these opportunities.
