Saiyid Ali Naqvi has brought a wealth of knowledge in water resources development, acquired over a 58-year career, to this study of the impact of the harnessing of the Indus waters on the evolution and development of the fabric of society in the region. He follows the Indus in its journey fromaround 7000 bc to present times, as he develops his thesis that the processes of social change in the region that now constitutes Pakistan are inextricably linked to the harnessing of the Indus waters. At its inception in 1947, Pakistan, with 85 percent of its population dependent on agriculture, was an agrarian country. Today, with two-thirds of its population still living in villages, the country remains dependent on agriculture. Despite the use of machinery by big landowners, the agrariansocial structure remains fettered by quasi-feudal and tribal customs. The book makes a critical assessment of the pace of the social change process in Pakistan and finds that it has reached a phase which could at best be characterized as "quasi-industrial". This disappointing situation is due to theslow pace of industrialization of the agriculture sector. The book provides the research, historical facts, and insights for an informed public debate on the policy measures for overcoming impediments and accelerating the social change process.
