Sustainable Gardening in our Continually Surprising Climate
I like nettles, when they’re managed – and grown in full view.
How can I grow food more successfully and sustainably on a tropical atoll in the Pacific? The high rate of evaporation negates our all year round rainfall. Our ‘soil’ is mostly hungry sand and decomposed coral which is highly alkaline.

What does it mean to be carbon positive? ‘Carbon neutral’ is a state that occurs when net greenhouse gas emissions are equal to zero. ‘Carbon positive’ means going beyond this, making additional ‘positive’ contributions to the environment. How can we achieve a carbon positive lifestyle?
These ecosystem engineers are thriving along the east coast of Australia. That’s just one message from Ann Goth’s new book ‘Amazing, Annoying Birds’, which explores these fascinating mound-building megapodes, expanding our knowledge about these much talked about colonisers of suburbia.
