Specifically, giving me the unprecedented opportunity of being taught Master‟s degree in Environmental Sciences in one of the most prestigious educational establishments in the world. As well as to undertake my internship at Tashkent Institute of Irrigation and Melioration. My heartfelt gratitude for both of my supervisors – Dr Andre van Amstel and Dr Alim Pulatov – for their guidance and support. By means of their advice and guidance, I was able to conquer my fear and to regard difficulties and obstacles as challenges, which I willingly and eagerly overcame. I am also appreciative of all the support my family and friends have given me. Their belief and encouragement was of the pivotal importance during toughest periods of my studies; and allowed me to find the power to keep on in situations where I was ready to give in and give up. 2 Table of Contents Preface ........................................................................................................................................ 2 Table of Contents ....................................................................................................................... 3 Abbreviations and Acronyms ..................................................................................................... 5 List of tables ............................................................................................................................... 6 List of figures ............................................................................................................................. 6 Summary..................................................................................................................................... 7 Chapter I.
