Methods and Studies for Preservation of the Natural Resources

The conservationist agriculture is the most important alternative for the preservation of natural resources, creating systems of conservation production, described in the literature as agroecossystem. In this system, all chemical inputs are drastically reduced or even no longer used. The key purpose of the conservationist agriculture: Produce food and preserve the environment. Besides, we - agronomist, biologist, and other professionals must explain this to our farmers. Another aspect is the climate change or global warming: conventional management of soils increases the CO2 content in the atmosphere, which is the main component for global warming, and consequently natural events (such as heavy rains), which will affect all people (from the countryside to the largest city). It is worth remembering that all literature is welcome, however, scientific literature is the main source of science (as the name already says), since the work for scientific publication is extremely complicated. All chapters refer about conservationist principles and all this contribute to minimize the climate change effects.
