La cesta di verdura

's view that the common problems associated with oil and global warming can be solved only from above, by our governments or international institutions like the UN .

We were wrong!

problems we can solve them only us ordinary citizens and consumers, radically changing our habits and thus inducing the various economic sectors to elaborate new systems of cultivation, production and distribution.

An example is described in the post of Eco Alfabeta purchase of organic vegetables delivered each week directly from the manufacturer at home.

Alfabeta Eco sums up 8 points, the benefits obtained in this way:

1. comes from farming, which does not use fertilizers and pesticides, fossil or other treatment agents.
2. is part of a short chain, very short indeed, since It is collected in the morning, walk a few dozen miles and reach the recipient shortly after. There are no middlemen.
3. are not used disposable plastic bags and baskets are continually reused.
4. just a half can deliver the vegetables to a number of people do not have to mobilize other cars.
5. The vegetables must be washed, cleaned and cooked, which stimulates the manual work and culinary creativity and eliminates the use of frozen vegetables.
6. There is no waste because the amount is right for the weekly number of eaters, so do not throw anything.
7. The manufacturer does not intend to deliver the vegetables over a distance its fields and does not intend to grow its business much beyond its current size, which are those of a family business.
8. The vegetables are always varied, fresh and delicious, very hearty soup of water and chemicals such as vegetables (fertilization with urea suggests a lot of water to the cells).

I add the following points:

• not using the cold chain and means of transport and refrigerated, with lower power consumption.
• is retrained local agricultural land through organic farming will be fertilized only with natural methods.
• We consume only vegetables and fruits in season getting used to the alternation of the consumer flavors in close relation with the changing seasons. It gives new breath to
• a local economy that will no longer be totally dependent on oil prices and international markets.

The last point can be realized only if consumers recognize the added value of organic agricultural products of short chain and if at the same time, the manufacturer gives all guarantees that its products are genuine and most importantly, I will never cease to repeat it, local !

A proposito di fertilizzanti !

And here you can already see in agriculture which are the consequences of rising prices del petrolio !!!

Debora Billi autrice assieme a Pietro Cambi del blog Crisis dedicato alla imminente crisi sistemica, annuncia in questo post l'aumento del prezzo dei fertilizzanti mentre addirittura in Inghilterra se ne lamenta la carenza sul mercato.

Ho sempre ritenuto che lo stretto legame tra agroindustria > chimica > petrolio, rendono tutto il sistema economico molto vulnerabile.

Quindi prima di preoccuparci se un domani ci sarà abbastanza carburante per le nostre auto, cominciamo a preoccuparci se ci sarà abbastanza da mettere sotto i denti !!!

I cinesi e gli indiani vogliono raggiungere lo stesso tenore di vita di noi occidentali, se l'agricoltura finds another way to support its production volume could we in the West to achieve their current standard of living, which would not be so dramatic, but it is difficult to imagine what would happen to all those people who still struggle to have enough food to a dignified life!

L'agricoltura e il petrolio

Modern agriculture has allowed the development of all other economic systems.
The higher yield of crops and livestock has freed farm workers, making possible the manufacturing revolution of the twentieth century and subsequently, the development of tertiary and computerization. The abundance
of food and the low value of agricultural products, in relative terms, has freed resources for the production and consumption of goods so-called "consumer".
Since modern agriculture is dependent almost exclusively on oil, this situation could change abruptly when oil production reached its peak, maximum crude oil production of good quality followed by decreasing trend.
Already today we see the first signs of the increase in the price of some food and we are still not certain that oil production has begun its decline!
But let us see why modern farming is so tied to the price oil and in the future because it will not be able to maintain the same levels of production even if the stable price of oil.
The mechanical revolution of agriculture in the first half of the twentieth century was followed by the chemical revolution through the use of inorganic nitrogen fertilizers, synthesized by petrochemical processes.
These revolutions have launched agricultural yields and at the same time sharply reduced the number of employees in the sector.
Consider, for example, a farmer in the mid-nineteenth century produced enough food to feed four people for seventy-eight today!
A small farmer producing an average of 10 calories for every calorie expenditure mentre oggi un moderno agricoltore statunitense può arrivare a 6000 calorie per ogni caloria di lavoro umano, ma qual'è il rovescio della medaglia?
Se ricalcoliamo la quantità di energia spesa tenendo conto di quella impiegata per la forza motrice e per la produzione di pesticidi e concimi azotati, allora il rapporto s’inverte drasticamente passando da una caloria spesa per produrne 10 a ....
10 calorie per produrne una !!!!
Questa situazione è tutt’altro che una posizione di equilibrio, anzi a causa dell’intensificazione delle pratiche agricole, la base del terreno si è impoverita ed erosa e per sostenere le rese è necessario utilizzare quantità crescenti di fertilizzanti sintetici.
The intensive monoculture has allowed economies of scale, increasing productivity, but also required increasing amounts of pesticides.
These pesticides deplete biological diversity and pollute groundwater.
The disappearance of microscopic bacteria, fungi, algae and protozoa, as well as worms and arthropods caused by pesticides, accelerates the process of erosion and soil depletion.
The result is an endless race to a higher energy input to maintain high crop yields by land poorer.
It is estimated that in the decades after World War II, the total energy input increased by 70%, but food production has grown by only 30%.
At this point we are left with only one road, the return to organic farming and traditional!
But the way in this direction will not be easy or immediate as the agricultural land treated with pesticides and chemical fertilizers can take more than a decade to return to natural fertility. The agricultural land
treated without chemical fertilizers produce only between 5 and 20% of what it produces today. Without
petrochemicals, which means a drop in productivity by 80 / 95%.
is why we can no longer afford to wait until the oil reaches such high prices to justify a massive conversion to organic / traditional.
We must now recover from those lands that have been treated for too long, we have to give back to the ground all that we have taken, and with interest!
If these choices will not be implemented from now, when oil and all its derivatives have reached unsustainable prices, we risk that the economic crisis that will result will lead to the abandonment of agriculture trade.
soils without chemical fertilizers, will soon become a barren land exposed to erosion!
