"This ongoing process has left many with a feeling of uncertainty about the future of their business and their town. With new environmental regulations comes change on a social, economic, and cultural level. This documentary ... explores how dairy farmers adapt amidst the changing landscape of what it means to farm sustainably."
Miss Walker told the Rotorua Daily Post New Zealand was a world leader in terms of sustainable farming.
"As for farmers in Rotorua, they are being asked to strike a balance between environmental and economic sustainability under nutrient limits that are far more strict than in other regions."
She said in terms of lake water quality the problems were inter-generational and were not just the fault of the farming community today.
"This generation of farmers are having to bear the burden of history. The average age of groundwater entering the lake is around 60 years old. Farmers are being asked to help restore water quality now so that future generations benefit."
She said the documentary would present a snippet of what life was like for farmers and their families and the paradox they faced with the government wanting to increase dairy exports but also wanting farmers to take more responsibility for the environment.
"The role of story-telling is for the viewer to see life from a different perspective, which hopefully leads to empathy and constructive debate over any finger pointing or increased tension."
She interviewed a range of local farmers for the film and attended council meetings.
