Invasive Alien Plants in Asia, Status & Controls

Background and Objectives:

The spread of alien invasive organisms has drastically increased in the past few years due to expanded worldwide trade and travel. Invasive alien plants directly damage the cultivated crops and cause imbalances in agro-ecosystems and also invade as weeds in natural environments - like National Parks. Therefore, the control of invasive alien plants is urgently needed in many countries, and here at NIAES, we have recently started a new national project on the risk assessment of invasive alien species.

Our aims in this NIAES International Symposium are to address the recent situation on the invasion of alien plants/weeds and their environmental risk/impact in different countries, and to discuss collaborative initiatives towards establishing international networks for agro-environmental research.
