Fundamentals of implementing the many negative factors In conventional agriculture, emerges the concept of organic farming that promotes agricultural production which relies on the conservation of natural resources in the production of basic foods such as ground water and biodiversity. These actions are based on respect for rural communities (who provide the genetic material of less pollution, almost genetically pure) and ethical and human principles in carrying out these activities. This farming promises to be highly productive and sustainable turn in output and long-term conservation in order to be able to solve the food supply to a growing human population.To meet this challenge, currently being developed science of agroecology which is defined as the application of ecological concepts and principles to the design and management of sustainable agroecosystems and involves the implementation of sustainable agricultural practices in technical and scientific knowledge of ecological processes agronomic, social and occur for production. In this perspective, design and management of sustainable agroecosystems can not and must abandon conventional practices but must look at traditional practices to justify their support. It is scientifically designing new concepts and technologies in agriculture, on the basis of methods and current ecological knowledge and traditional principles of conservation of natural resources that many rural communities have and those that cover their food needs without requiring large external inputs their production cycle.European countries, followed by other highly industrialized countries such as USA and Australia, are leading in implementation of agroecological principles in their agricultural development policies. However, several countries in Latin America, Asia and Africa are implementing national agricultural projects that consider environmental protection. It highlights the case of Venezuela, where the new national constitution included in article number 305 the following: “The State shall promote and develop agro-ecology as a strategic base for integrated rural development in order to ensure food security and sovereignty of the people , understood as the sufficient and stable availability of food at the national level and timely access and continuing them by the consuming public. “.
