"The debate on drought and other important issues will be held during the session. Therefore, they (opposition) should co-operate," Chavan told reporters.
"Due to consecutive droughts since two years, the state has been facing tremendous water scarcity. There is a serious drinking water shortage in Marathwada and Western Maharashtra. The next four months will be crucial," he said.
To help the state government during this crisis, the opposition should co-operate, he said.
To take measures on drought, the Chief Minister's Relief Fund has been set up and generous people may contribute, he said.
