Droughts will become more common, as will extreme weather events. Relative humidity will decrease and evapotranspiration will increase. I believe that planning our landscapes to meet these changes will increase our chances of successfully localising our food supply.Recently there has been interest in developing a tropical fruit industry in Northland. I suggest that by adopting mixed plantings of alley crops on contour with appropriate soil building techniques (such as the Yeoman’s plough on contour), water harvesting techniques (such as swales and vetiver grass), and minimisation of soil cultivation through direct reseeding, I believe that we can reduce risks while maximising production, minimising input costs, maximisi…..
