river based agriculture

Taking Shiyang River basin as an example, agricultural water resources are optimized through regional virtual water trade in the basin. Biocides can contaminate water, especially of slow-flowing rivers, and are responsible for a number of fish kills each year. Untreated industrial chemical wastes can alter the normal biological activity of rivers, and many of the chemicals react with water to raise the acidity of rivers to a point where the water becomes corrosive enough to destroy living organisms. CSA, or community-supported agriculture, is based on a mutually beneficial relationship between the farm and the people who consume our food. With a history of at least 5,000 years, controlled irrigation now affects roughly 2,000,000 square kilometres (770,000 square miles) of land, three-quarters of it in East and South Asia and two-fifths in mainland China alone. Hydroelectric power generation was introduced more than 100 years ago, but the majority of the existing installations have been built since 1950. China Agriculture is one of the most important sector of economy and as the statistics suggest the China Agriculture provides more than 12 percent of the total Gross Domestic Product or the GDP in the country.. More than 300 millions people in china are related with China Agriculture which is almost 50 percent of the total work force that China has got. Plus, did you know a Sheep's wool is so good at CO2 sequestration it's one of the best on the planet? [7], Much of the history of the Indus valley civilization is unknown. The water may develop a bad taste and is unfit for human consumption unless filtered and specially treated. In effect, rivers are used as open sewers for municipal wastes, which results not only in the direct degradation of water quality but also in eutrophication. Egyptians are credited as being one of the first groups of people to practice agriculture on a large scale. In agricultural areas the extensive use of phosphates and nitrates as fertilizers may result in other problems. Although upper limits for concentrations of unquestionably toxic chemicals such as arsenic, barium, cyanide, lead, and phenols have been established for drinking water, no general rules exist for the treatment of industrial wastes because of the wide variety of organic and inorganic compounds involved. The long-lasting flood kept farmers from harvesting food, put construction projects on hold, and halted barge traffic on the Mississippi River from … Preventing Runoff Into The Mississippi River Exit. [2][3], Civilizations tended to grow up in river valleys for a number of reasons. A "civilization" means a society with large permanent settlements featuring urban development, social satisfaction, specialization of labor, centralized organization, and written or other formal means of communication. Agricultural Management. Results show that compared with the situation in the year 2007, the net benefit of agriculture, the fairness difference in the utilization of water, and the proportion of green water utilization are optimized. Navigate parenthood with the help of the Raising Curious Learners podcast. Under normal conditions, algae contribute to the oxygen balance in rivers and also serve as food for fish, but in excessive amounts they crowd out populations of other organisms, overgrow, and finally die owing to the exhaustion of available nutrients and autointoxication. Connecting to Clean the Ganges River. The first great civilizations, such as those in Mesopotamia, Harappa and Ancient Egypt, all grew up in river valleys. A river valley civilization is an agricultural nation or civilization situated beside and drawing sustenance from a river. The Egyptians would rotate legumes with cereal which would stop salt buildup from the freshwater[clarification needed] and enhance the fertility of their fields. Even the port of London, though constrained by high capital investment, has displaced itself toward its estuary. Agriculture, which accounts for 70 percent of water withdrawals worldwide, plays a major role in water pollution. The fourth great river civilization emerged around 1700 BCE along the Yellow River in China. By contrast, there are some countries, such as Norway and Switzerland, that depend almost entirely on hydropower for their various electrical energy needs. Agricultural wastes from agro-based industries, such as palm oil, rubber, and wood processing factories have increased by more than threefold. The first civilizations formed on the banks of rivers. One of the cities within this civilization, Ur, was the first literate society in history. Figure 1.1. Demand on open-channel water increases as population and per capita water use increase and as underground water supplies fall short. 2. Moreover, even in cases where a government-imposed ban checks the further discharge of certain dangerous substances into waterways, the chemicals may persist in the environment for years. The widespread use of such biocides and the universal nature of water makes it inevitable that the toxic chemicals would appear as stream pollutants. PCBs have been found in high concentrations in the fatty tissues of fish, which can be passed up the food chain to humans. It has been estimated that 75 percent of the potential hydropower in the contiguous United States has been developed, and about 13 percent of the total annual electrical energy demands of the country are met by hydroelectric power plants. Mesopotamian cities became self-run civil governments. In addition to the production of a wide range of valuable agricultural commodities, the Sacramento region is home to numerous multi-national agricultural corporations and statewide governmental agencies. The historical record includes marked shifts in the appreciation of rivers, numerous conflicts in use demand, and an intensification of use that rapidly accelerated during the 20th century. Various species of bacteria then begin to decay and putrefy the dead algal bodies, the oxidation of which sharply reduces the amount of oxygen in the river water. [6], Mesopotamia was one of the earliest river valley civilization, starting to form around 4000 BCE. Commodity-carrying laker in the St. Lawrence Seaway at Montreal, Canada. Most of this activity involves the use of natural floodwater, although reliance on artificially impounded storage has increased rapidly. Entering rivers via rainwater runoff and groundwater seepage, these chemicals can cause eutrophication. CRC’s Department of Nutrition and Foods offers an Associate’s Degree Program that is challenging, accessible, and rewarding. Plentiful water and the enrichment of the soil due to annual floods made it possible to grow excess crops beyond what was needed to sustain an agricultural village. Since PCBs cannot be broken down by conventional waste-treatment methods and are degraded by natural processes very slowly, scientists fear that these compounds will continue to pose a serious hazard for decades to come. Reliable data for these kinds of dependence on rivers do not exist; published estimates that freshwater and migratory fish provide up to about 15 percent of world catch may be too low. Runoff from agricultural fields often contains eroded soil, fertilizers, animal manure, or pesticides that together form a major source of water pollution. Selangor, Perak, and Johor collectively account for 65.7% of the total number of identified sources of pollution in the manufacturing and agro-based sectors ( DOE, 2010 ). The Sources and Solutions: Agriculture. The domestication of plants and animals are reported in the subcontinent by 9000 BC. Use demand of more immediate kinds are related to freshwater fisheries (including fish-farming), to dwelling in houseboats, and to recreational activities. The Amazon remains naturally navigable by ocean ships for 3,700 kilometres (2,300 miles), the Yangtze for 1,000 kilometres, and the partly artificial St. Lawrence Seaway for 2,100 kilometres. Also, canalization, with its extensive system of locks and navigation dams, often seriously disrupts riverine ecosystems. Building a commercial enterprise out of the wilderness required labor and lots of it. An accumulation of PCBs in the human body is known to induce cancer and other severe disorders. Large power plants and other industrial facilities are often located along rivers, which supply the enormous quantities of water needed for cooling purposes (see below). After a period of decline from the later 1800s to about the mid-1900s, water transport of freight has steadily increased. Furthermore, recreational use of rivers has increased over the years. Ammonia can be harmful to aquatic life if large amounts are deposited from the atmosphere to surface waters. This allowed for some members of the community to engage in non-agricultural activities such as the construction of buildings and cities (the root of the word "civilization"), metalworking, trade, and social organization. Eventually, they constructed irrigation systems to exploit the two rivers, transforming their dry land into an agriculturally productive area, allowing population growth throughout the cities and states within Mesopotamia. [1] A third civilization grew up along the Indus River around 3300 BCE in parts of what is now India and Pakistan (see Bronze Age India). A major impetus for the tribes to unite into a single kingdom by around 1700 BCE (Erlitou culture, a Yellow River civilization) was the desire to find a solution to the frequent deadly floods. From: Woube, 1999. A "civilization" means a society with large permanent settlements featuring urban development, social satisfaction, specialization of labor, centralized organization, and written or other formal means of communication. Is the Ganga River in southern India? Manuring The excavation of the Mehrgarh period sites that is around 8000-6000 BC throws some startling facts about Indian agriculture that began as early as 9000 BC. Land-based agriculture on the Columbia River has slowly left the region, leaving behind a tangle of broken levees. It also may cause rapid depletion of the oxygen supply by promoting algal blooms. Congo River - Congo River - The people and the economy: Three types of environments are found, either juxtaposed or in succession, along the river and its tributaries: the narrower sections, bordered by firm ground; the wider stretches, dotted with islands and accompanied by backwaters; and the zones where flooding occurs or where there are extensive marshes. An example of this is the formation of sulfuric acid from the sulfur-laden residue of coal-mining operations. In North America many waterways, particularly those with relatively light commercial traffic, support large numbers of recreational craft.
