This week we have a host of great ideas inspired by solutions we've told you about in 2023.

We find out how scientists are using fake birds to help populations of seabirds to recover. By putting out model birds in restored habitats they trick the real ones into nesting there.

Then we have the heartwarming tale of Theo – a man in his seventies - and Bickel the dog. We look at how dog sharing can deal with loneliness and bring improved health and happiness.

And we uncover an innovative way of dealing with the scourge of Japanese knotweed - by turning it into paper.
