Forestry experts are warning that the UK needs to plant more trees for timber. We import around 80% of the timber we use, but there are fears of a shortage of wood for house building, pallets or fencing if more conifer plantations aren't created. MPs on the all party group on forestry are discussing the issue. We speak to the industry body Confor which says we can grow they type of wood we need.

Feijoas are a popular fruit in New Zealand but a bit of a mystery to most Brits. The fruit isn't really imported and until now it wasn't grown here. Well, that changed when a New Zealander in Sussex had an idea. We meet the couple behind a new growing enterprise.

All week we're focusing on sustainability in farming, whether that's from an environmental point of view, resilience in supply chains or from a financial perspective. Farming is seasonal and unpredictable, which can make it hard to plan financially - veg growers for example find it hard to predict how much they'll earn from one month to the next. Margins are tight and prices don't necessarily reflect the cost of production. We speak to a producer and campaigner who's part of a cooperative which would like to see a basic income for all farmers.
