Sistan Basin
The Sistan Basin is an inland endorheic basin encompassing large parts of southwestern Afghanistan and minor parts of southeastern Iran, one of the driest regions in the world and an area subjected to prolonged droughts. Its watershed is a system of rivers flowing from the highlands of Afghanistan into freshwater lakes and marshes and then to its ultimate destination: Afghanistan's saline Godzareh depression, part of the extensive Sistan terminal basin. The Helmand River drains the basin's largest watershed, fed mainly by snowmelt from the mountains of Hindu Kush, but other rivers contribute also. A basalt hill, known as Mount Khajeh, rises beside the lakes and marshes of the basin. Lakes The lowest part of the Sistan Basin contains a series of shallow lakes, known as '' hamuns''. It appears that in the past there was a single Hamun Lake, but there are now three separate lakes. From north to south the lakes are: Hamun-e Puzak The Hamun-e Puzak lies mostly in Afgha ...

Hamuns
A hamun (or hamoun) ( fa, هامون ''hāmūn'') refers to inland desert lakes or marshlands, formed as natural seasonal reservoirs in areas adjoining the Helmand basin, found across eastern Iran, southern Afghanistan and western Pakistan. They form a critical link in the wildlife of the area, aquatic as well as avian and terrestrial. The better-known hamuns include: *Hamun-e Helmand, Afghanistan and Iran **Hamun Lake, Iran and Afghanistan * Hamun-e Jaz Murian, Iran *Hamun-e Mashkel or Mashkid, Balochistan mainly in Pakistan and border. *Hamun-e Puzak, Afghanistan *Hamun-e Saberi in Sistan Sistān ( fa, سیستان), known in ancient times as Sakastān ( fa, سَكاستان, "the land of the Saka"), is a historical and geographical region in present-day Eastern Iran ( Sistan and Baluchestan Province) and Southern Afghanistan ( ..., straddling Iran-Afghanistan border *Hamun Zeheh, Goad-i Zereh or Godzareh depression, Afghanistan References Geography of Ce ...

Shahr-i Sokhta
Shahr-e Sukhteh ( fa, شهر سوخته, meaning " heBurnt City"), c. 3200–2350 BCE, also spelled as ''Shahr-e Sūkhté'' and ''Shahr-i Sōkhta'', is an archaeological site of a sizable Bronze Age urban settlement, associated with the Helmand culture. It is located in Sistan and Baluchistan Province, the southeastern part of Iran, on the bank of the Helmand River, near the Zahedan-Zabol road. It was placed on the UNESCO World Heritage List in June 2014. The reasons for the unexpected rise and fall of the city are still wrapped in mystery. Artifacts recovered from the city demonstrate a peculiar incongruity with nearby civilizations of the time and it has been speculated that Shahr-e-Sukhteh might ultimately provide concrete evidence of a civilization east of prehistoric Persia that was independent of ancient Mesopotamia. Archaeology Covering an area of 151 hectares, Shahr-e Sukhteh was one of the world's largest cities at the dawn of the urban era. It is located close to th ...

Archaeology
Archaeology or archeology is the scientific study of human activity through the recovery and analysis of material culture. The archaeological record consists of artifacts, architecture, biofacts or ecofacts, sites, and cultural landscapes. Archaeology can be considered both a social science and a branch of the humanities. It is usually considered an independent academic discipline, but may also be classified as part of anthropology (in North America – the four-field approach), history or geography. Archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. Archaeology is distinct from palaeontology, which is the study of fossil remains. Archaeology is particularly important for learning about prehistoric societies, for which, by definition, there are no written records. Prehistory includes over 99% of the human past, from the Paleolithic until th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Delta
A river delta is a landform shaped like a triangle, created by deposition of sediment that is carried by a river and enters slower-moving or stagnant water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, or (more rarely) another river that cannot carry away the supplied sediment. It is so named because its triangle shape resembles the Greek letter Delta. The size and shape of a delta is controlled by the balance between watershed processes that supply sediment, and receiving basin processes that redistribute, sequester, and export that sediment. The size, geometry, and location of the receiving basin also plays an important role in delta evolution. River deltas are important in human civilization, as they are major agricultural production centers and population centers. They can provide coastline defense and can impact drinking water supply. They are also ecologically important, with different species' assemblages depending on their landscape posit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agriculture
Agriculture or farming is the practice of cultivating plants and livestock. Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in cities. The history of agriculture began thousands of years ago. After gathering wild grains beginning at least 105,000 years ago, nascent farmers began to plant them around 11,500 years ago. Sheep, goats, pigs and cattle were domesticated over 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. Industrial agriculture based on large-scale monoculture in the twentieth century came to dominate agricultural output, though about 2 billion people still depended on subsistence agriculture. The major agricultural products can be broadly grouped into foods, fibers, fuels, and raw materials (such as rubber). Food classes include cereals (grains), vegetables, fruits, cooking oils, meat, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecology
Ecology () is the study of the relationships between living organisms, including humans, and their physical environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere level. Ecology overlaps with the closely related sciences of biogeography, evolutionary biology, genetics, ethology, and natural history. Ecology is a branch of biology, and it is not synonymous with environmentalism. Among other things, ecology is the study of: * The abundance, biomass, and distribution of organisms in the context of the environment * Life processes, antifragility, interactions, and adaptations * The movement of materials and energy through living communities * The successional development of ecosystems * Cooperation, competition, and predation within and between species * Patterns of biodiversity and its effect on ecosystem processes Ecology has practical applications in conservation biology, wetland management, natural res ...

Handicraft
A handicraft, sometimes more precisely expressed as artisanal handicraft or handmade, is any of a wide variety of types of work where useful and decorative objects are made completely by one’s hand or by using only simple, non-automated related tools like scissors, carving implements, or hooks. It is a traditional main sector of craft making and applies to a wide range of creative and design activities that are related to making things with one's hands and skill, including work with textiles, moldable and rigid materials, paper, plant fibers,clay etc. One of the oldest handicraft is Dhokra; this is a sort of metal casting that has been used in India for over 4,000 years and is still used. In Iranian Baluchistan, women still make red ware hand-made pottery with dotted ornaments, much similar to the 5000-year-old pottery tradition of Kalpurgan, an archaeological site near the village. Usually, the term is applied to traditional techniques of creating items (whether for perso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Livestock
Livestock are the domesticated animals raised in an agricultural setting to provide labor and produce diversified products for consumption such as meat, eggs, milk, fur, leather, and wool. The term is sometimes used to refer solely to animals who are raised for consumption, and sometimes used to refer solely to farmed ruminants, such as cattle, sheep, goats and pigs. Horses are considered livestock in the United States. The USDA classifies pork, veal, beef, and lamb (mutton) as livestock, and all livestock as red meat. Poultry and fish are not included in the category. The breeding, maintenance, slaughter and general subjugation of livestock, called '' animal husbandry'', is a part of modern agriculture and has been practiced in many cultures since humanity's transition to farming from hunter-gatherer lifestyles. Animal husbandry practices have varied widely across cultures and time periods. It continues to play a major economic and cultural role in numerous communities. ...

Reed Bed
A reedbed or reed bed is a natural habitat found in floodplains, waterlogged depressions and estuaries. Reedbeds are part of a succession from young reeds colonising open water or wet ground through a gradation of increasingly dry ground. As reedbeds age, they build up a considerable litter layer that eventually rises above the water level and that ultimately provides opportunities in the form of new areas for larger terrestrial plants such as shrubs and trees to colonise. Artificial reedbeds are used to remove pollutants from greywater, and are also called constructed wetlands. Types Reedbeds vary in the species that they can support, depending upon water levels within the wetland system, climate, seasonal variations, and the nutrient status and salinity of the water. ''Reed swamps'' have 20 cm or more of surface water during the summer and often have high invertebrate and bird species use. ''Reed fens'' have water levels at or below the surface during the summer an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wetland
A wetland is a distinct ecosystem that is flooded or saturated by water, either permanently (for years or decades) or seasonally (for weeks or months). Flooding results in oxygen-free (anoxic) processes prevailing, especially in the soils. The primary factor that distinguishes wetlands from terrestrial land forms or Body of water, water bodies is the characteristic vegetation of aquatic plants, adapted to the unique anoxic hydric soils. Wetlands are considered among the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal species. Methods for assessing wetland functions, wetland ecological health, and general wetland condition have been developed for many regions of the world. These methods have contributed to wetland conservation partly by raising public awareness of the functions some wetlands provide. Wetlands occur naturally on every continent. The water in wetlands is either freshwater, brackish or saltwater. The main wetland ty ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
