will be decreased. in most of this water goes into agriculture so we have one to irrigate and produce food and in a dry area so the amount of water we have in middle east is enough for for satisfying our drinking and sanitation needs it s not enough to produce food with it or make the region self-sufficient in food production but this is something that the region has not understood well. now if you draw your soil if you use a lot of water and waste a lot of water then you should expect a punishment which is called a dust or and that s something we have been punished for in the middle east because of not using water properly because a losing soil moisture. for the hook one example of the consequences of poor water management is neko tonia in
across the world are doing further tests that add to the analysis. claire cook is a mineralogist at the university of sheffield in the u.k. . she leads in a bar a tree studying soil and dust particles but not now is the dust and a scanning electron microscope and not a moment when mike and i played three hundred times as the scale bar on this image is fifty microns it runs in the suit these principles are really really very smooth and that s an individual one but they also will marry all together. in big clumps so you can see there s a whole different distribution of sizes some of them very small and some of. the chemical elements can also be identified by the microscope ok so this is not elements would not have been done some just tonight up would have been to the individual elements so you hazel original sample of dust with very bright spots. and i m not right it s seems to correspond to some let s which may be present as
tigris river we found a huge amount because this war affected by war activities multiple war activities so drained farms and abundant farms became a huge source of dust in fact from this region. the city of us in who is a stand southwestern iran is now one of the most polluted cities on the planet partly because of dust blowing in from iraq. the marshlands in southern iraq a grossly affecting all our western southwestern cities like that was. part of it is also coming from neighboring countries and are coming from the hot spots that we have inside the country in the areas which are prolonging to soil erosion. was. only two sectors twenty fourteen ten was hit by
in kuwait sorry s team are experimenting with native doesn t plans to try to stabilize the soil. these drought tolerant plants have extensive root systems which help prevent soil from blowing away this is really our area was a party area in the boston quiett though it is prohibited in question two thousand and three so all the quarters was dumped and zeal for detention was in this area before now areas rehabilitated again by using native plants in order to form a very good native life in the region. we ve planted about one hundred ten thousand native plants in the area music native plants captured huge amount of dust and sand around the plant it wasn t there before so this. is formed by the
atmospheric dust has always being with us and there are some benefits. this is a very positive impacts from dust storms blowing around the planet many of the soils in the caribbean islands the clays came from north africa and it enabled the pre-columbian indians to build plate clay pottery and without that dust blowing across and building up in the soils the clay wouldn t be in the caribbean you wouldn t find. dust also contains valuable nutrients for plants. so when the rain forests from north africa the dust flows over it goes into south america during the north northern hemisphere is winter and moves down and there. and many of the plants derive their nutrients and are fertilized from the last in the end the same with asian dust blowing across fertilizers some of the northern hawaiian island rain forests and sustains them so there s some very positive things
