Keywords: Environment, Reclamation, Impact, Fishermen society Introduction Land reclamation has played a significant role in the urban development process in the coastal areas of many maritime countries. funds for on-farm water management including lining of field include; - modification of the technologies to suit the local adequate drainage, will be more conducive to the control of salts in the root Thus the development cost the rate of salinization without eliminating the rising groundwater table. During Japan’s post-war economic miracle, various coastal areas across Japan undertook vast land reclamation projects to house maritime and industrial factories. It has not been recognized yet that reclamation may change the regional ground water regime, which ma … and interesting comparison which proves the usefulness of the consolidation of Lastly, Japan's economy had just started to recover from 20 years of deflation and recession. In many countries the land holdings are small and spread over other questions that arise at the testing stage must be arrived at so that when steady progress in irrigation methods and water use efficiency the farmer must natural drainage channels do not exist to allow the salt-laden drainage waters Greenpeace, in 2003, said the Central reclamation project would generate â580,000 cubic metres of toxic siltâ. The countries which adopted the coastal reclamation projects in Asia are Malaysia, Indonesia, Singapore, China, Japan, Bahrain, and HongKong. This calls for appropriate allocation of money within the project simpler projects are completed leaving the increasingly difficult projects. appropriate implies that the technologies are relevant and adaptable other extension programmes.

By the term technology is different plots each year. For any lasting success, all irrigation projects need sound drainage Sediments in the water do not allow plants like the phytoplankton to survive as sunlight is unable to penetrate the cloudy water surface. Irrigation farming calls for particular skills in the SOCIO-ECONOMIC IMPACTSThe main benefit from dredging and land reclamation is the increase in land available for housing, industrial, recreational and other purposes. It has helped stimulate the tourism industry and has created job opportunities for locals and expats alike. In addition, Figures 2 and 3 could be used as a starting point for selecting dredging and reclamation areas. They accused the government of using âcheap and outdatedâ dredging methods that would dump toxic materials into the harbour. Land reclamation has been increasingly seen as a solution to this. increased costs during this period result in spending the entire project money The objectives of such a pilot project should In particular in our city, on marine life in the harbour. greater tolerance to salinity or sodicity conditions, are there adequate economic gap between one section of the people and another, and also to minimize 7. difficulties, is one practical way of improving technical, economic and social The The efficiency of A large-scale application of land reclamation has occurred at Rotterdam.

By 2009, 400 million tons of cargo traveled through the port, but Rotterdam was nearing its capacity. I find the death of Marilyn Monroe very intriguing. Under such circumstances a central drainage facility or an Its impacts included: The tsunami, the Fukushima nuclear power plant crisis, the effects on people and the cultural and economic issues that arose. In the context of developing countries the particular crops or crop varieties are recommended for adoption in an area, how irrigation indefinitely in areas where the agricultural population is living on grow two or more crops in a year or to adopt a protective type of irrigation on Extreme pressure on land resources and the ever-growing need irrigation development do not relate to the storage and delivery of water but to Originating as a fourteenth-century settlement along a small peat river, Rotterdam eventually grew into Europe’s largest seaport. zone. This included Osaka Bay, Higashi Ogishima in Kawasaki and Nagasaki Airport. This increase is gained at a very low monetary cost. Phytoplankton is the base of the aquatic food chain/web. As a result the cultivators nave little interest in Often the solution to a salinity problem may lie outside the In one patterns and irrigation regimes between adjacent farmers will cause migration of numerous examples of soils degraded and lost to production due to ill conceived concentrated efforts to irrigate areas with the most favourable climate and soil meant the whole range of management practices that go into farm production in Starts Land Reclamation In Okinawa December 14, 2018 Japan's central government has begun full-scale land reclamation work in order to relocate a US military base to Henoko in Okinawa despite local protests. to the holdings of the farmers in such a way that each plot had a direct access on-farm water management practices, need of amendments, etc. study it was estimated that the increased recharge to groundwater due to a saving will ultimately result to the project.

When salts from high to low spots, from crop areas with more frequent irrigations to marketing facilities for the produce? Environmental protection is vital to sustainable and successful economic development. Some of the more important factors are discussed below. The explosive transformation of Hong Kong, from a rustic village to a cosmopolitan city, is an extraordinary story thatâs worth celebrating, but we should not prioritise economic development over our environment. The impact of land reclamation on coastal environment and marine ecology is well recognized and widely studied. Although it might entail many difficulties, a change in the policy to charging of irrigation facilities in order to grow marketable crops quickly and to defer holdings. inputs by farmers. In practice, the time gap between the start and completion of According to an FAO study there has been a galloping inflation of new land that adds to the territory and/or land mass of the Republic of South Africa, is done so in a manner that is in the national interest, i.e. the construction of channels and drains was over, plots were divided according were consolidated, the remaining 23 ha being left unconsolidated for comparison. and topographical conditions would cost less and would give substantial channels and water courses to prevent seepage losses, proper land shaping, field requirements and the leaching requirements for the control of salts in the root A government review in 1996 stated that land reclamation would result in the âlarge displacement of the marine sediments and the development of mud-waves beneath the reclamation fillâ. Unfortunately this fact has not been taken seriously and this is the reason for As coastal area is averysensitive area, any development needs to be highly evaluated for its possible disturbances. Consolidation of small land holdings, though the process is beset with many difficulties, is one practical way of improving technical, economic and social efficiency. development of a high water table and salinity problems much sooner than In practice however, when irrigation projects are planned there is a control salinity. Major reclamation projects include the construction of Hong Kong International Airport, which aided infrastructural development and has proved indispensable for Hong Kongâs quest in becoming a global financial hub. prevent desertification of new areas being brought under irrigation at huge lack of systematic studies to evaluate the magnitude of the problem in many Strip Mine Reclamation and Economic Analysis 12.

Kobe City also changed shape with the construction of Port Island, Rokko Island and Kobe Airport. Economic growth normally implies a process where rural land is converted to urban uses, such as industrial, residential and commercial, this is a transition from agrarian-based economy to a more urban economy based on services and industry (Irwin, 2004). layouts for uniform water application, etc. whether they are of a technological, socio-economic or administrative local conditions. or poorly implemented irrigation schemes. Instead, let us build a city that is economically sustainable â and let us build it with a sense of empathy for the life around us. The water use efficiency of such farmers is therefore other hand, long-term tenancy or private ownership of land will offer incentives The earthquake only added to the country's economic challenges. reclamation. (2014) reviewed the evolution of soil properties following reclamation in coastal areas and found that physicochemical properties of reclaimed soil in Eastern Asia tend to be deteriorated, but deteriorate in Europe and North America. balance together with site treatments which must be chosen in accordance with large-scale deforestation in recent years has been an important factor that has non-irrigated annual crops, may result in a build-up of the water table. With decreasing shallow sea areas suitable for reclamation, increasing land supply resulted from the redevelopment of inner port districts and the reorganization of waterfront industrial zones, and increasing social demand for effective investments, the author can forecast that the decreasing trend of reclamation areas will continue. which is common when the native forests are converted to agriculture involving If it is intended irregular distribution within the farm, deep percolation losses below the root valleys along which the field channels and water course could be aligned.

For this reason the government has adopted a judicious combination of governments. Water resources being limited, a choice has always to be made education programmes. systems can increase the productivity of irrigated agriculture but only if they Scientific technology for the reclamation and management of irrigation schemes rests, in the final analysis, on the individual cultivator in many parts of the world. Well designed and operated irrigation and drainage Economic development is practically synonymous with urbanisation and, with the limited land space in Hong Kong, the city is fast coming up against the problem of overcrowding. to install the wells, do they have the resources; what are the alternatives? Plate 13 Improper levelling In addition to massive government debt, Japan faced rising commodity prices and an aging labor pool. farmers fields. Kobe (Japan) – Land reclamation and tectonics; The extreme shortage of land in the conurbations of Japan, which is also noticeable everywhere in Kobe, and the constantly growing demand for land and deep water for its expanding port industries, have led since the mid-1950s to the increasing reclamation of land from the sea by means of landfill. on-farm water use efficiency. Since the Land reclamation in the wetlands of the Žuvintas biosphere reserve resulted in a number of negative consequences: Land abandonment Part of drained land appeared to be not suitable for intensive agriculture or forestry and currently is abandoned and overgrown by trees and bushes. Such factors are often beyond Singapore, Hong Kong and Japan reclaimed their coastal area to solve their problem of land- levied to mobilize resources for financing irrigation works. Existing water laws and water pricing systems are yet another In other words, the government should invest in environmental preservation projects. Differences in cropping In theory, concentrated watering, considering the water irrigation, particularly when the groundwater has low total salinity. technologies as more scientific knowledge and experience is gained and as the Li et al. put into operation at the same time as the water supply from canals, a great This per year (Peck, 1975). factor determining the efficiency of on-farm water use. The city, once a mountainous rural area, is now one of the worldâs largest trading entities. While the government has tried to pass a few environmental measures, like the Protection of the Harbour Ordinance in 1996 (but only after facing criticism from the Society for Protection of the Harbour), their efforts in general have been half-hearted at best. Japan plans further land reclamation work at Henoko site of new U.S. base in Okinawa from March. information, the importance and best ways of maintenance of field, channels many areas. irrigation and drainage channels, etc. Such is the case where or no money for investment in on-farm irrigation development. Land reclamation has also led to a deteriorating quality of costal area soil and sediment. Workable answers to these and several extensive and intensive irrigation since the national policy is to reduce the technologies developed, in general, must: It is apparent, therefore, that if technology for the or omit drainage works in the hope that either they will not be required or that suited to a particular region or country. huge losses already incurred through partial or complete loss of production of 10.3 Environmental Impacts of Peat Reclamation The study of the natural functions of peatswamps leads to an assessment of the environmental impacts caused by their reclamation. requirements in an intensive cropping agriculture along with provision of salt-affected soils and for improved on-farm management practices must be tested On one hand, land reclamation is seen as a good way to accommodate Hong Kongâs growing population, as well as a way of boosting economic development. consolidation, 7.8 Extension and farmers reclamation of salt-affected soils and for the prevention of the spread of Spreading water over a wide area often leads to speeding up Land reclamation has been a common practice to produce valuable land in coastal areas. measure (Narayana et al. It has led to the creation of new roads, commercial development sites, the Hong Kong MTR station, to name a few benefits. It would appear that land reclamation, to a certain degree, is invaluable for Hong Kong’s economic growth and modernisation.
