    Colonial Economy

    The concept of "colony" is historically dated and helped organize a specific trade net where the center of the colonial empire (French, Belgian, English, Dutch…) had a direct administrative power for planification of production programs in these "colonies". In a hierarchic logic, these centers favoured their own economical needs sometimes to the detriment of the population needs of the colonized countries. This system gave birth to exchange networks which were not based on the proximity or on the economic complementarity of neighbouring countries but on "exchange networks binding these centers to their colonies" During the period of decolonization (between 1950 and 1970), such commercial agreements were stopped little by little. The former colonized countries had to join the international market, i.e. to adapt to a strongly concurrencial environment and to the needs of new clients or new countries.

    Food Producing Cultures

    It means both plants which can be sold and which can be transformed and eaten by the producer. Therefore, in periods when money is short or time difficult for sales, the farmer can always survive with his family.

    Perrenial Cultures:

    Such plants can last in the soils more than one year and bear fruits several times. The best example is the tree of an orchard : once planted into the ground, it bears fruits periodically. For a farmer this feature makes of a cultivated land (the orchard) an investment, as a bank account producing regular interests (the fruits).

    Internationnal Market

    At the beginning, "the market" was a physical space of trade between a product and its monetary value. The "market square" of some villages can illustrate this definition. With the geographical development of the trade and of the information connections, the market became a theoretical place where offers are face to face with needs. Negociations now lies in agreements between a seller and a buyer, though not a single real product is exchanged between them. Such agreements are negociated in the frame of "commercial exchanges ". In order to guarantee the trade rules , the transactions are made through professional traders and by agents of big international trading companies. Close to the knowledge of the stock exchange ups and downs on products and currencies, these agents are the best to anticipate prices variations and to take the best profit of it. The main Stock Exchange markets are located in the USA, in England, in Japan. New places arise like Singapour. Most of the tropical countries are not used to such trade though their economic fate can depend on it.

    Tropical Products

    In the frame of the Agropolis Museum exhibitions, the terminology "tropical products" is narrowed to agricultural products and more specifically to the ones cultivated on large scales in the intertropical area. Nevertheless, this situation is not unchanging, for progress in genetic sciences can "climatically adapt" a plant initially found in tropical ecological areas. This is the case for the potatoes and the maïze (american corn) which are commonly grown now in France.
