Growing plants by floatigation using biochar in salt / brackish / polluted / flood - evaporated water using sun light and rain water harvesting.. This presentation is prepared to meet the challenge of growing plants on all water bodies and also harvest clean water. In this method a float saucer shaped, covered with a transparent plastic sheet is designed which will take only required quantity of water for evaporation through use of sunlight and heat. The water vapour would condense on the transparent sheet and harvested into the biochar container. There is also a safety pipe inserted in the biochar for outflow of excess water and also to tap fresh water. The rainwater is also collected from the top and reaches the biochar. Such floats created could be used on all types of water bodies where it is difficult to grow terrestrial plants such as slat water areas – bays, seas, oceans; brackish water and marshy water areas; on the polluted water bodies; during the floods on flood waters, etc. This is one of the environmental solutions for mitigation and adaptation- in extreme conditions provides – food and water. This concept is best described under the concept of “permabiocharculture”
