What is ecology according to Ana Primavesi

Everyone talks about ecology and imagines the conservation of natural reserves, of some animal like the golden lion, the conservation of a tree like the Brazilian wood, and the maintenance of a variety of wheat or flax. Well, they want to keep something and they always think it depends on our good heart and maybe our culture.

For example, every time it rains, there are floods in the cities and partly also in the countryside. The population curses the city council for not taking action, but in fact the culprits are the inhabitants of the cities who claim paved streets, cement the patios of their houses and take care of them so that there is no place to go. they can dirty their shoes.

They are also demanding that the city council leave the grass in the parks, removing all grass clippings because they think it is getting ugly. Thus, the soil without organic matter is compacted and rainwater does not find a place to enter the soil. Where is he supposed to go? Course. And as everyone in his garden does the same, the water suddenly flows and that’s why there is a flood.

If everyone had a small garden, if the grass could maintain its cover which one usually removes to “decorate the ground” and which disappears by itself in two days, the water would have a place to seep . On the other hand, they say that water in cities is scarce and sidewalks and cars should not be washed. What’s the point of that?

Also in vegetable gardens, when planting huge lettuces or broccoli or beets, intensive treatment is necessary. Herbicides keep the soil clean of all native plants. The fertilizer that is applied weekly makes the plants grow, every other day they are sprayed with poison to protect them from insects, sometimes every day, just as they are watered daily… It’s hard and expensive, but is it necessary ?

If an orchard or a garden is planted, letting the volunteer grasses grow, people think that the orchard or the garden has been lost, that they cannot even appreciate the planting of so many native plants that grow. And people often despise these lands because they think they won’t harvest anything. And even with 3 months of drought, without a drop of water, it did not affect the garden. The roots have been mixed together, one helping the other, the only 8cm deep are still wet and the garden looks much better than intensively grown plants with daily treatments. Because? It is biodiversity that allows one plant to enter the root space of another. In monocultures this is not possible, since all the plants need the same thing and the spaces must be defended with violent poisons against spontaneous plants.

South of Bahia there is a peasant who plants in the middle of the native land, or better still, in a cultivated capoeira. Plant corn and beans, pineapple and lettuce, pumpkins and roses and more, all in one intensive mix. (OBS: She was referring to Ernst Götsch) And every time you add more crops, they all grow even better. Of course, there are plants that we don’t like and others that make peace like sunflowers and tomatoes, or chickpeas and sunrise, or onions and beans, or herbs. sweet that no other vegetable likes. I hope these don’t get confused. But even so, when they are in the middle of the jungle, they are not as hostile as in the monocultures in the field. And when the ground breaks there are intense tangled roots where one helps the other and the ground is quite spongy and permeable.

This is why forests are needed to capture water. But a “forest” of eucalyptus or pine trees that are monocultures that kill native plants is useless.

Monocultures are planted by mechanization and not because they produce more. Soil protection has now proven to be a key factor for good production. That is why planting is done directly with a thick layer of straw or densely with coffee, corn, cotton, vegetables, etc. Back to biodiversity, in which the soil is protected, without monoculture but with biodiversity: in the cocoa tree, where banana trees, palm trees, erythrinas and other legumes are now planted, to recover lands in terrible decline… common. It comes down to biodiversity because the land produces more and is healthier, that is to say because it has much better developed roots and better conserves the soil and therefore the water.

Little by little, man understands that he cannot dominate nature but must obey its laws by entering the ecosystem. All the techniques that seemed like a breakthrough were just a step towards the destruction of our world. Because? Because they have eliminated ecosystems and biodiversity and attacked natural laws.

The temperature is more pleasant under a tree, the water is more abundant under a native forest, the rain is milder and the wind is less intense in the regions with forests and the production is greater when one obeys the laws of nature. , as shown by the Asians who, with their method, produce twice and up to four times more than conventional agriculture without fertilizers, without agrochemicals. But there is one condition: living alone and biodiversity.

It is therefore not out of kindness that we should maintain the forests and the biodiversity of the countryside, but simply because our survival depends on it.

Ecology is therefore the practice of reproducing what nature already does. Or try to have as little impact as possible (because agriculture always ends up having an impact), always promoting more life in the ecosystem.
