Available in PDF, EPUB and Kindle. Book excerpt: This report presents an overview of the geology, hydrology, and climate of the lower Helmand Basin, a large, closed, arid basin in southern Afghanistan. The basin is drained by the Helmand River, the only perennial desert stream between the Indus and Tigris-Euphrates Rivers. The Helmand River is the lifeblood of southern Afghanistan and has supported desert civilizations in the Sistan depression for over 6,000 years. The Helmand Basin is a structurally closed basin that began to form during the middle Tertiary as a consequence of the collision of several Gondwanaland fragments. Aeromagnetic studies indicate the basin is 3-5 kilometers deep over basement rocks. Continued subsidence along basin-bounding faults in Iran and Pakistan throughout the Neogene has formed the Sistan depression in the southwest corner of the basin. Lacustrine, eolian, and fluvial deposits are commonly exposed in the basin and were intruded by latest Miocene-middle Quaternary volcanoes, which indicates that depositional environments in the lower Helmand Basin have not substantially changed for nearly 10 million years. Lakes expanded in the Sistan depression during the Quaternary; however, the size and extent of these pluvial lakes are unknown. Climate conditions in the lower Helmand Basin likely mirrored climate changes in the Rajasthan Desert to the east and in Middle Eastern deserts to the west: greater aridity during global episodes of colder temperatures and increased available moisture during episodes of warmer temperatures. Eolian processes are unusually dominant in shaping the landscape in the basin. A strong wind blows for 120 days each summer, scouring dry lakebeds and creating dune fields from annual flood deposits. Nearly one-third of the basin is mantled with active or stabilized dunes. Blowing winds combined with summer temperatures over 50° Celsius and voluminous insect populations hatched from the deltaic wetlands create an environment referred to as the "most odious place on earth" by 19th century visitors. During dry years, large plumes of dust originating from Sistan are recorded by weather satellites. The Helmand River drains about 40 percent of Afghanistan and receives most of its moisture from melting snow and spring storms. Similar to many desert streams, the Helmand and its main tributary, the Arghandab River, are characterized by large fluctuations in monthly and annual discharges. Water from the Helmand accumulates in several hamuns (shallow lakes) in the Sistan depression. The wetlands surrounding these hamuns are the largest in western Asia and are directly affected by droughts and floods on the Helmand. Average annual discharge on the Helmand is about 6.12 million megaliters (million cubic meters), and the annual discharge varies by a factor of five. In 2005, the region was just beginning to recover from the longest drought (1998-2005) of record back to 1830. Annual peak discharges range from less than 80 cubic meters per second in 1971 to nearly 19,000 cubic meters per second in 1885. Large floods fill each hamun to overflowing to create one large lake that overflows into the normally dry Gaud-i Zirreh basin. The interaction of flooding, active subsidence, and wind erosion causes frequent channel changes on the Helmand delta. A major development effort on the Helmand River was initiated after World War II with substantial aid from the United States. Two dams and several major canals were completed in the 1950s; however, poor drainage conditions on the newly prepared agricultural fields caused extensive waterlogging and salinization. New drains were installed and improved agricultural methods were implemented in the 1970s, and some lands became more productive. Since 1980, Afghanistan has endured almost constant war and civil and political strife. In 2005, the country was on a path to rebuild much of its technical infrastructure. Revitalization of agricultural lands in the lower Helmand Basin and improved management of surface- and ground-water resources are crucial to the country's reconstruction efforts.
Download or read book Transboundary Water Resources in Afghanistan written by John F. Shroder and published by Elsevier. This book was released on 2016-06-13 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transboundary Water from Afghanistan: Climate Change, and Land-Use Implications brings together diverse factual material on the physical geography and political, cultural, and economic implications of Southwest Asian transboundary water resources. It is the outgrowth of long-term deep knowledge and experience gained by the authors, as well as the material developed from a series of new workshops funded by the Lounsbery Foundation and other granting agencies. Afghanistan and Pakistan have high altitude mountains providing vital water supplies that are highly contentious necessities much threatened by climate change, human land-use variation, and political manipulation, which can be managed in new ways that are in need of comprehensive discussions and negotiations between all the riparian nations of the Indus watershed (Afghanistan, China, India, and Pakistan). This book provides a description of the basic topographic configuration of the Kabul River tributary to the Indus river, together will all its tributaries that flow back and forth across the border between Afghanistan and Pakistan, and the basic elements that are involved with the hydrological cycle and its derivatives in the high mountains of the Hindu Kush and Himalaya. Synthesizes information on the physical geography and political, cultural, and economic implications of Southwest Asian transboundary water resources Offers a basic topographic description of the Indus River watershed Provides local water management information not easily available for remote and contentious border areas Delivers access to the newest thinking from chief personnel on both sides of the contentious border Features material developed from a series of new workshops funded by the Lounsbery Foundation and other granting agencies
Download or read book Natural Resources in Afghanistan written by John F. Shroder and published by Elsevier. This book was released on 2014-06-04 with total page 593 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural Resources in Afghanistan: Geographic and Geologic Perspectives on Centuries of Conflict details Afghanistan's physical geography — namely climate, soils, vegetation, water, hazards, and basic geologic background and terrain landforms — together with details of its rich natural resources, ethnic problems, and relevant past histories. The book couples these details with the challenges of environmental degradation and new environmental management and protection, all of which are considered finally in both pessimistic and optimistic modes. The reader comes away with a nuanced understanding of the issues that are likely to have great affect for this pivotal region of the world for decades to come. With an estimated $1-3 trillion dollars of ore in the ground, and multiple cross-reinforcing cancellations of big Asian power machinations (China, India, Iran, Pakistan), Afghanistan has an opportunity to gain more economic independence. At the same time, however, historic forces of negativity also pull it back toward the chaos and uncertainty that has defined the country and constrained its economic progress for decades. - Authored by the world's foremost expert on the geology and geomorphology of Afghanistan and its lucrative natural resources - Aids in the understanding of the physical environment, natural hazards, climate-change situations, and natural resources in one of the most geographically diverse and dangerous terrains in the world - Provides new concepts of resource-corridor development in a country with no indigenous expertise of its resources

Available in PDF, EPUB and Kindle. Book excerpt: In the 1970s, in his capacity as government representative from the Afghan Institute of Archaeology, Ghulam Rahman Amiri accompanied a joint Afghan-US archaeological mission to the Sistan region of southwest Afghanistan. The results of his work were published in Farsi as a descriptive ethnographic monograph. The Helmand Baluch is the first English translation of Amiri’s extraordinary encounters. This rich ethnography describes the cultural, political, and economic systems of the Baluch people living in the lower Helmand River Valley of Afghanistan. It is an area that has received little study since the early 20th Century, yet is a region with a remarkable history in one of the most volatile territories in the world.
Download or read book Design and impact of water treaties written by Matthew Zentner and published by Springer Science & Business Media. This book was released on 2011-10-13 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study presents a unique way to utilize the existing literature to explain the success of treaties in managing hydrologic stress. Literature-derived core concepts are summarized as seven treaty mechanisms categories (specificity, uncertainty management, enforcement, communications, flexibility, integrativeness, and scale) and are hypothesized as important for shaping the institutional resiliency of a treaty. Treaty design is shown to have a relevant and important role in shaping basin management so that nations may better achieve their goals in a changing climate.

Download or read book Afghanistan written by Jonathan L. Lee and published by Reaktion Books. This book was released on 2022-03-08 with total page 797 pages. Available in PDF, EPUB and Kindle. Book excerpt: A colossal history of Afghanistan from its earliest organization into a coherent state up to its turbulent present. Located at the intersection of Asia and the Middle East, Afghanistan has been strategically important for thousands of years. Its ancient routes and strategic position between India, Inner Asia, China, Persia, and beyond has meant the region has been subject to frequent invasions, both peaceful and military. As a result, modern Afghanistan is a culturally and ethnically diverse country, but one divided by conflict, political instability, and by mass displacements of its people. In this magisterial illustrated history, Jonathan L. Lee tells the story of how a small tribal confederacy in a politically and culturally significant but volatile region became a modern nation-state. Drawing on more than forty years of study, Lee places the current conflict in Afghanistan in its historical context and challenges many of the West’s preconceived ideas about the country. Focusing particularly on the powerful Durrani monarchy, which united the country in 1747 and ruled for nearly two and a half centuries, Lee chronicles the origins of the dynasty as clients of Safavid Persia and Mughal India: the reign of each ruler and their efforts to balance tribal, ethnic, regional, and religious factions; the struggle for social and constitutional reform; and the rise of Islamic and Communist factions. Along the way, he offers new cultural and political insights from Persian histories, the memoirs of Afghan government officials, British government and India Office archives, and recently released CIA reports and Wikileaks documents. He also sheds new light on the country’s foreign relations, its internal power struggles, and the impact of foreign military interventions such as the “War on Terror.”

Download or read book Transplanting Modernity written by Thomas B. Robertson and published by University of Pittsburgh Press. This book was released on 2023-10-24 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: In general, “development” denotes movement or growth toward something better in the future. International development—widespread in the decades following World War II—was an effort at purposeful changein landscapes around the world. Contributors to this volume argue that these projects constituted an effort to transplant modernity, such as knowledge or technology, from places seen as more developed to places perceived as un- or underdeveloped. During its heyday, international development included not just dams, roads, health programs, and agricultural projects but also animal husbandry schemes, urban development, and wildlife protection plans. Projects often succeeded or failed because of existing environmental conditions, and in turn, these programs remade—or tried to remake—the land, water, wildlife, and people around them. From American-directed failures in water engineering in Afghanistan to the impact of livestock epidemics on economic growth in East Africa, the chapters in Transplanting Modernity question how science, technology, and faith in Western notions of progress have influenced the pace, scope, and scale of development.
