One of the most important problems facing us as a result of climate change is the lessening of our water supply. Therefore, for future agricultural production and to guarantee the use of residential water, we must maintain the surface and ground water in its current adequate state, and to use it in an ecological manner. During the past decade and a half due to ecological management, and the considerate use of the water supply, we have proven that within the 200 hectares of the eco village of Somogyvámos, today the ground water is safe to drink, and the high nitrate content of 15 years ago today are under medical safety levels.
