Well, italki is not a place for providing translation services but I have done the best I can considering the weakness of my Spanish and the limited amount of time I have available. The urgent need to combat rural poverty and regenerate the damaged productive resource base of small farmers, has encouraged some global NGOs, to actively seek new types of resource management strategies and agricultural development while respecting participation, experience and knowledge of farmers, increase productivity without degrading productive resources. Agroecology has helped define a new agricultural strategy in the production process of small farmers, which differs radically from the Green Revolution or other mechanization and modernization approaches based on the use of large quantities of inputs. Commodity production can only take place in the context of a social organization that protects the integrity of natural resources and allows harmonious interaction of humans, the agroecosystem and the environment. Agroecology provides methodological tools for community participation becomes the driving force in defining the objectives and activities of development projects. The goal is for farmers to become architects and actors in their own development.

If you need to translate "Resumen sobre agroecología" then I think "Overview of Agroecology" is probably what you are looking for. It would help if you could provide some context. Is this the title of a report?
