UOE TRIP 1 DAY 3 THE DIRT ROAD TO DE RUST

John introduces us to agroforestry. Agroforestry is something that was practiced by previous generations of farmers in the form of poplar trees, which was introduced to provide fast-growing trees, and timber to service the farming operations in the early days. With the advent of modern farming, and the fact that metal has become cheaper than renewable wood. This leaves many woodlands undermanaged. we need to look at reinventing the utilisation of something like that. Agroforestry is not something new, but something that has been practiced in the past. The trees provide shelter from the wind, holding water into this environment, providing a refuge for animals, recycling minerals, trapping energy from the sun and bringing it back into the soil.

John interestingly discusses how trees actually form water and don’t just deplete environments of water.

We stop at an area where a fire has ravished the land. Destroyed vegetation. Bare soil and desertification unfolding before our eyes. Altogether it is a threat to the future of our planet.

We stop at a commercial irrigation system. The sustainability of this practice raises a lot of questions and the prospects of future generations are being undermined. Tilling of the land is discussed as well as soil conservation. We then see the dam with the water from the high tillage regime… lots of soil runoff. The water also becomes extremely salty due to the salts from fertilizers, and becomes less effective for irrigation.
