Ethnic communities inhabiting Jharkhand state are living in true harmony with nature. They entirely depend on plants and plant resources for their livelihood. Plants use in tribal belt is as diverse as the ethnic diversity. The paper focuses on lesser known nutraceutical plants, usually  not known to the modern society but form an important dietary part of the ethnic people and provide them both nutritional and health security. These vegetables are lesser known and under-utilized resources, which are rich both in nutrients and secondary metabolites, providing nutritional and health security (nutraceutical). These plant resources grow their own, thrive easily on inhospitable conditions without any input, give new taste and are free of chemical pesticides and insecticides. In view of the large scale utilization of land area in the name of various kinds of developmental activities there is an urgent need of enlisting wild nutraceutical potherbs and documentation of their therapeutic uses before it is too late. The present paper describes 35 plants species which are widely consumed amongst ethnic communities.

  Water plays a vital role in human life .The total amount of water, below and on the surface of the earth has been estimated to be 1.33x1024 kg. Which is about 5% of the total mass of the earth .The consequences of urbanization and industrialization leads to spoil the water. For agriculture purposes, ground water is utilized in rural areas, especially in those areas where other sources of water like dam and river or a canal is not available. In India, most of the population is dependent on ground water supply. The ground water is believed to be comparatively much clean and free from pollution than surface water. Ground water is used for domestic and industrial water supply and irrigation all over the world .In the last few decades, it has been seen that there is a tremendous increase in the demand for fresh water due to rapid growth of population and accelerated pace of industrialization. Human health is threatened by most of the agricultural activities particularly in relation to excessive application of fertilizers, pesticides, irrigation practices and unsanitary conditions.
