Production de cresson à haut risque dans les bas fonds d’Antananarivo ?

Population growth and urban development in the South renew research topics on agriculture. Advantageous in some respects, urban agriculture entails many risks, especially those related to the quality of irrigation water and to urban farmers’practices. The article illustrates the case of Antananarivo...

description	Population growth and urban development in the South renew research topics on agriculture. Advantageous in some respects, urban agriculture entails many risks, especially those related to the quality of irrigation water and to urban farmers’practices.
