I'm very fortunate and grateful to wake up every morning in the rural countryside I live in, looking at farmland and these beautiful mountains.

When it comes to portfolios, my personal advice is for anyone who can, put money into forestry or farmland. Long term, you would probably never come near their returns in the stock market. In the world that I see, land is golden.

We have serious challenges regarding climate change, unsustainable use of natural resources, water scarcity, loss of biodiversity, forests and farmland. Not to mention the huge inequality still prevailing in several parts of the planet.

Human settlements are like living organisms. They must grow, and they will change. But we can decide on the nature of that growth - on the quality and the character of it - and where it ought to go. We don't have to scatter the building blocks of our civic life all over the countryside, destroying our towns and ruining farmland.
