I found it very interesting to listening about your move from annuals to perennials agricolture.
Climate is changing, still I'm not sure wether it's goind towards desertification: where I'm cultivating, northern Italy, we had an extremely drought year -- last year -- while this year is raining almost every single day. So at the beginning of this season I was just concerned in getting the biggest water tank that I could, to collect rain water and be ready for another drought summer. Eventually it turned out that I never had to water plants until now, as it's raining so generously.
Now I'm wondering wether the climate is changing from stable and predictable seasons towards unstable and unpredictable seasons.
