"A Climate of Change" by Jenny Sharman, one of the films being screened at the ongoing 7th CMS Vatavaran Environment and Wildlife Film Festival showcases how African communities experience the changing of climates, which are impacting negatively on their ability to sustain a livelihood from land.
"...It is now an era where behavioural change is necessary if we are to mitigate, and adapt to, the impacts of global warming," Jenny Sharman to PTI over an email interview.
The 2012 movie was the finalist at the Montana Film Festival.
Born and brought up in Kenya, Jenny has made films on wildlife for BBC, National Geographic and Discovery Channel.
