AGRICULTURE AS A RESULT OF ECOSYSTEM SERVICE.

We need to think that an ecosystem is working for us all time, proving a constant flow of resources as economical input, sustain life and all necessary condition for the agricultural activity, creating a mechanism that is wider than our comprehension. An agricultural ecosystem is producing food, fuels, non-food products. This activity is depending on the ecosystem service, by water, climate, soil fertility, carbon sequestration, biodiversity as genetic reservoir. Usually the connection between agriculture and ecosystem service is limited at landscape or negative impact of agricultural practices. But it is observed that ecosystem services in the current global context are generating productivity losses and put us in the situation to adapt our economic system, by adopting new technologies and policy changes. Lack of resources, in quantity and quality, water scarcity, extreme weather conditions, flooding, lack of soil nutrients, pests' control, biodiversity depreciation, emphasize our close dependence by the ecosystem. Ecosystem service evaluation is an important instrument for territorial planning, sustainable resource exploitation, nature protection, conservation and restoration, new bio-based business models design, climate protection. This paper work is analyzing the connection between agriculture and ecosystem services. [ABSTRACT FROM AUTHOR]
