Oil and gas have been the primary concern for many environmentalist groups. However, there is a new concern that needs urgent attention. The world is slowly running out of clean water. Many places in the world suffer from severe water shortages such as Nepal. The residents in such areas have to buy water from private vendors. It has caused a major headache for a majority of the population. Many developing countries struggle with the same problem.
It is estimated that more than a billion people have no access to fresh water. The population of the world is growing rapidly. Therefore, it means that we need more water to cultivate more crops to feed the population. It has been suggested before that we could remove the salt content from sea water and use it on plants. Australian greenhouses use solar energy to desalinate seawater and grow crops. The farmers in those areas have had to come up with new ways to support agriculture in their region.
Plant scientists are researching on plant genes that would do well in arid conditions. They aim at introducing the key cells of drought tolerant plants to crops through genetic engineering. Traditionally, farmers have used pollination to try and crossbreed different species of plants to come up with more draught-resistant breeds. However, this process is slow.
There have also been studies on root architecture systems in different chickpea plants. Scientists are trying to identify the gene that makes the plant’s roots efficient in capturing nutrients and water from dry soils. Most of the draught-resistant plants have abscisic acid (ABA). The acid increases the plants’ water retention capacity. However, it also reduces the efficiency and rate of photosynthesis. It is vital that we come up a way to cultivate draught-resistant plants for our survival.
