The aim of this symposium is to bring together knowledge on sustainable techniques of vegetable production, with emphasis on South East Asia. The emphasis of the symposium is on nutrient supply, fertilization, organic matter management and soil quality, but also other aspects of sustainable vegetable production including crop protection can be dealt with. Apart from oral and poster presentations on these topics, there will be dedicated sessions in working groups on at least two important cross-cutting issues: inventorization of existing research projects on sustainable vegetable production in the region (including ways how to better match these initiatives, and possibly leading to new project applications). A second is on education/training/exttension in vegetable production
