THE INDUS RIVER
The Indus River is one of the world's great rivers. It rises in the Himalayas, firstly flowing north westwards and then turning south to flow throughout the whole of Pakistan before entering the Arabian Sea via the Indus delta east of Karachi. During its journey, it flows through the dramatic mountain scenery of Gilgit and Jamshur and the North West Frontier Province of Pakistan, and then across the fertile flood plains of the Punjab and arid desert regions of Sindh.
Equally important, the river and its impact on the surrounding countryside via its dams, barrages, and unique canal systems, affects the working conditions and living standards of virtually the entire population of Pakistan. There are already problems with deforestation, erosion, silting, waterlogging, salinization, and desertification, and these will increase in the future.
Pakistan has a population of about 120 million which makes it one of the ten most highly populated countries in the world. Its population is likely to double within about 25 years, and so its population growth is also amongst the highest. These extremely high and rapidly increasing population levels are placing an ever increasing pressure on all of the environments within the catchment area of the river.
Much of the recent economic developments in Pakistan have centred on the direct or indirect use of water from the river. In terms of energy requirements, for example, hydroelectric energy represents 15 percent of the country's needs and contributes about half of the electricity demand. The future development potential is in principle very high.
Indirect use of the water from the river is also of great importance to the economy of the country because it is also used in the production of non-commercial energy. Fuel wood, dung, and agricultural waste all of which are used as energy sources for cooking in urban and rural poor areas.

The scientific and academic establishments of the developed countries, with a few notable exceptions, are largely unaware of the extraordinary range of ecosystems, biodiversity, mineral resources, and demographic history of the unique system represented by the Indus River and its surrounding lands. This and the sociological implications of the dramatic growth of human populations along the river's length meant that an international symposium devoted to all aspects of the river was of great timeliness.
With this background, the Indus River Symposium, held at the Linnean Society of London in 1994 brought together international experts from developed and developing countries to assess for the first time our present state of knowledge about the way the Indus river system works and to develop new multidisciplinary approaches to the long term management of its resources. The symposium aimed to encourage discussion and dialogue on planned environmental management of the whole catchment area from a holistic point of view. This enabled future scenarios on enhanced resource development to be evaluated while at the same time protecting the unique biodiversity of the wide range of ecosystems along the river's length.
The papers presented at the symposium together with papers provided by contributors who could not attend, fell into three major sections.
1. Biodiversity, environmental conservation and management, and living resources
2. Hydrology, geomorphology and geology of past and present environments
3. Archaeology, prehistory and anthropology of sites of human habitation
The informal discussions at the end of the papers presented at the symposium are included.
Recommendations are included at the end of the symposium volume.
BIODIVERSITY, ENVIRONMENTAL CONSERVATION MANAGEMENT, AND LIVING RESOURCES
There is now a global interest in environmental conservation and management and the preservation of the world's biodiversity. There are many endangered ecosystems and rare species in and along the Indus and its tributaries. Man also makes considerable use of the environment for forestry, agriculture, fisheries and fish farming. There is hence considerable interest in both the natural and modified populations of animals and plants and their habitats, particularly in relation to pollution.
The Wildlife of the Indus River and Allied Areas
By Mohammad Farooq Ahmad.

Tom Roberts provides a pictorial view of the River Indus and its environmental resources as affected by human activity, with a wide range of examples from wildlife conservation, irrigation systems, and surviving river cultures.
HYDROLOGY, GEOMORPHOLOGY AND GEOLOGY OF PAST AND PRESENT ENVIRONMENTS.
The past and present environments of the Indus River have played a major role in determining the geographical distribution of mineral resources of the areas bounding the river. Changes in water, soil and sediment transport on a seasonal and long term basis are also frequent, and these have inevitable consequences for desertification, waterlogging, salinization and flood forecasting. There is therefore considerable interest in the mineral resources, hydrology and geomorphology of the river system and its associated land.

Postscript: The editors are very sorry to report that Dr S.M. Shuaib, senior author of the above paper and Professor of Geology at Karachi University, passed away in February 1996. He was an outstanding geologist and made a wide range of important contributions to the geology and hydrocarbon prospects of Pakistan.
ARCHAEOLOGY, PREHISTORY AND ANTHROPOLOGY OF SITES OF HUMAN HABITATION.
The archaeology and prehistory of sites in Pakistan are some of the richest in the world dating from more than 8000 years ago. These have to us as a species, and present interest has meant that there is a rapidly developing tourist industry relating to these sites, which brings its own problems. In addition, the changing patterns of human occupation, trade and transport affect and have been affected by the changes of land form and coastline. In this section and also elsewhere in the introduction we have spelt Mohenjo Daro thus, to ensure consistency. However we appreciate that there are a number of alternative spellings.
Excavations at Hund on the Banks of the Indus: the Last Capital City of Gandhara.
By Ihsan Ali.
Ihsan Ali describes the ancient city of Hund that lies on the west bank of the Indus River on the Peshawar Plain, and gives an account of recent excavations that he and colleagues have conducted there. The ruins of the city now lie under the village of Hund on the river bank, which is situated about half way between Attock and Tarbela Dam.
Some Questions of Environment and Prehistory in the Indus Valley from Palaeolithic to Urban Indus Times.

Indus River Dynamics and the Abandonment of Mohenjo Daro.
By Michael Harvey and Stanley Schumm.
Michael Harvey and Stanley Schumm discuss the importance of the dynamic nature of the Indus in Sindh, and the significance of this in leading to the abandonment of Mohenjo Daro.
Mohenjo Daro and the River Indus.
By Michael Jansen.
Michael Jansen provides recent evidence for the vertical extent of anthropogenic material from the ancient city of Mohenjo Daro. Michael Jansen feels that the enormous undertaking involved in building a city of this sort almost de novo - if this is what happened, was dictated by the rapid development of riverine transport and communication along the Indus together with a west - east trade route between Quetta and the Rohri Hills.
Ecological Changes in the Headwaters of the Indus.
By Karl Jettmar.
Karl Jettmar in a paper on ecological changes in the headwaters region of the Indus, outlines the early domestic use of humped cattle as revealed by studies in Swat, and then discusses the subsequent use of goat breeding which he suggests was caused by the destruction of vegetation by fire.
Prehistoric Population and Settlement in Sindh.
By Gregory Possehl.
Gregory Possehl describes settlement data which have been used to deduce relative changes in population size during the prehistoric period in Sindh. As Gregory Possehl points out, this starts at a very early stage in mans history at about 7000 BC with the appearance of village communities in the lower Indus Valley encompassing Sindh and the Kachi Plain.
The Indus - River of Poetry.
By AnneMarie Schimmel.
AnneMarie Schimmel captures the interest that poets have taken in the River Indus and explores the reasons which inspired their poems and the symbolism that the river holds for them.
The Historical Geography of Indus Basin Management. A Long-Term Perspective 1500-2000.
By James Wescoat.
James Wescoat provides a thought-provoking analysis of the history of the management of the Indus basin particularly during periods of territorial instability and conflict between 1500 and the present day.
All of these contributions show very clearly that national and international multidisciplinary initiatives by governmental and non-governmental organisations are urgently required to ensure the protection of the Indus River system into the 21st century and beyond. Only in this way can the system be managed and conserved for future generations of mankind. These matters are considered in detail by the contributors in the recommendations at the end of the volume.
One of the most important requirements in all future work on the Indus River and its surrounding lands is for coherent multidisciplinary programmes involving an integrated and holistic approach to the environment. This will require detailed co-operative plans to be formulated during the early stages of programme development, and will need careful co-ordination within Pakistan, and on an international scale.
In view of the complexity of many of the sites and ecosystems that require study, groups of specialists having a range of scientific and cultural expertise will be needed in most of the programmes. Furthermore, the initial stages of many of the programmes are likely to involve the collation of information that is at present only available from scattered sources.
The recommendations agreed by delegates, which are based on the topics covered during the symposium, emphasised the urgent need for integrated research, conservation, management and restoration in a number of critical target areas of the Indus River and its surrounding regions as follows.
There is an immediate need for multidisciplinary research projects that will establish baseline information and provide databases for future economic utilization, conservation, planning and management.
The projects will involve the investigation of sites throughout the length of the Indus River and its surrounding lands: the Himalayas and Himalayan foothills, the Siwalik Hills, the central flood plain, the deserts, deltaic region, mangrove swamps and coastal zone.
Comprehensive integrated programmes of conservation are needed in view of the rapid degradation associated with human activities in the following areas -
- Archaeological sites.
- Endangered ecosystems.
- Animal and plant species many of which are endangered and some of which require protection.
Management and Restoration
Urgent programmes of integrated management and restoration are required for a number of sites associated with the River Indus and surrounding areas, because of their resources, economic value, cultural significance and importance to local populations. Many of the sites also have great tourist potential.
