Overall objectives:
According to the United Nations Codex Alimentarium "Organic Farming is defined as the set of agricultural production practices, subject to certification, based on the primary use of natural resources and raw materials, the minimal use of synthetic substances, whether in pest control, fertilization or in the correction of natural soil characteristics."
However careful and responsible, the organic farming practices may not always necessarily guarantee that products are completely free of any residues deriving from synthetic agro-substances, due to non-point environmental pollution, which will determine or influence the quality of agricultural produces. The externalities from diverse anthropogenic activities may impact organic farming through two main vectors, indeed vital resources, namely air and water.
This course will have as a main tenet the introduction of fundamental concepts in the field of hydrology, showing methodological alternatives for the use of water resources in agricultural production, and the demonstration of how environmental conservation policies, pertaining to water recycling and its sustainable use, can and should be the basis of all agricultural production.
Syllabus:
1) introduction of basic hydrology concepts;
2) considerations regaring site selection taking into account the availability of water resources;
3) discussion of key challenges and factors responsible for changes in production quality regarding the quality of water;
4) presentation and recommendation of the main analytical methodologies in most common contamination screening;
5) indication of viabilizadoras techniques and methodologies of conservation, recycling and optimization in the use of water in agricultural production;
6) storage and distribution systems to support the irrigation of agricultural crops;
7) water as a factor of integration and boosting agricultural communities.
