Banana more resistant to climate change: Scientists

Bananas thrive in southern India's tropical climate - the states of Tamil Nadu, Kerala and Karnataka produce more than 27 million tonnes of the fruit a year. Farmers in India are already recognising it as the most reliable source of income. Al Jazeera's Sohail Rahman reports from Hoseharrli in Karnataka, India.
