Farmers in Scotland have criticised what they say is the government's 'lack of joined up policy' after it emerged that over the past 23 years nearly 16 million trees have been felled to make way for wind farms. The Scottish government says that there is a planning presumption to protect woodland and that developers would be expected to plant trees elsewhere to make up for the loss.
All this week we鈥檙e looking ahead to 2050 when, if the government hits its target, the UK will have reached net zero emissions of the greenhouse gases contributing to climate change. So what should and could farming and the food system look like? It's a question we've put to a range of people over the week, farmers, conservationists and today an architect turned writer who has given a lot of thought to food and its place in our lives.
Carolyn Steel is the author of Hungry City: How Food Shapes Our Lives and Sitopia: How Food Can Save the World. She argues that food is a powerful force and we don't give it the value it deserves.
