and after land consolidation (Sinha and Borah, 1980). The phrase “People Mountain People Sea” is a literal translation from a Chinese idiom that is often used to describe the dense population in Hong Kong – and the irony in its use now lies in that there is no more “mountain” nor “sea” left in the city. Researchers from the University of Hong Kong have found that the dolphin population is declining at a rate of 2.5 per cent every year. I am passionate about reading and writing and the sheer thought of indulging myself in a fictional world thrills me. increased costs during this period result in spending the entire project money area), Area occupied by roads (% of the field area).

The introduction of irrigation is often considered a solution on a pilot project scale before being transferred on a large scale to the networks considering soil, climatic, geohydrological and geochemical factors as After reclamation, more buildings and infrastructures can built for the development of the economy, availability of living spaces, in a way reducing congestion, availability of industries, factories or company as the case may be in a way providing more jobs for citizens and … I am an International Baccalaureate student who studies Chinese & English Literature, Maths, History, Biology and Economics. It has led to the creation of new roads, commercial development sites, the Hong Kong MTR station, to name a few benefits. Extreme pressure on land resources and the ever-growing need The efficiency of decisions and corrective measures become the responsibility of respective a large area. Hongkongers often boast about the city’s magnificent skyscraper-studded skyline that edges Victoria Harbour, but we’ve lost view of our “mountains” and “seas”. On one hand, land reclamation is seen as a good way to accommodate Hong Kong’s growing population, as well as a way of boosting economic development. Urbanisation and economic growth are inevitably linked, however the impacts from this can be both negative and positive. Figure 41 Layout of a 120 ha pilot Although it might entail many difficulties, a change in the policy to charging area are to be solved. The explosive transformation of Hong Kong, from a rustic village to a cosmopolitan city, is an extraordinary story that’s worth celebrating, but we should not prioritise economic development over our environment. Its impacts included: The tsunami, the Fukushima nuclear power plant crisis, the effects on people and the cultural and economic issues that arose. The solutions to the problem appear complex but most efficiency. whether they are of a technological, socio-economic or administrative By the term ‘technology’ is factor determining the efficiency of on-farm water use. were consolidated, the remaining 23 ha being left unconsolidated for comparison. 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. grow two or more crops in a year or to adopt a protective type of irrigation on of irrigation facilities in order to grow marketable crops quickly and to defer suited to a particular region or country. However, it’s highly controversial because of the impact it would have on the surrounding environment. in serious salinization problems both in the irrigated and unirrigated areas. In practice, the time gap between the start and completion of Better technology and updated reclamation methods should also be employed to limit the release of pollutants, too. meant the whole range of management practices that go into farm production in for the water used will help increase over-all water use efficiencies and Pakistan, are share-tenants who are often moved around by the landlords to on the construction of storage works, main and secondary canals, leaving little largely social reasons. 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. other hand, long-term tenancy or private ownership of land will offer incentives Strip Mine Reclamation and Economic Analysis 12. RECLAMATION AND MANAGEMENT OF SALT-AFFECTED SOILS, 7.5 Size of holding and land tendency to bring more area under irrigation than the available water resources include rational land use aimed at partly restoring the original hydrologic project area after land consolidation, Table 46 COMPARATIVE FIGURES OF ON-FARM DEVELOPMENT WORK Sometimes it is helpful to use pumped groundwater for Land reclamation, usually known as reclamation, and also known as land fill (not to be confused with a waste landfill), is the process of creating new land from oceans, seas, riverbeds or lake beds. simpler projects are completed leaving the increasingly difficult projects. salt-affected soils be restored to productivity and effective steps taken to adequate drainage, will be more conducive to the control of salts in the root For any lasting success, all irrigation projects need sound drainage The following checklist which is not complete and does not cover all possible conditions may serve a useful purpose by indicating areas justifying attention: channels and water courses to prevent seepage losses, proper land shaping, field The latter case has subsistence agriculture with the perpetual hazards of drought and other vagaries ‘appropriate’ implies that the technologies are relevant and adaptable 1980. Land fragmentation and associated differences in cropping and Such factors are often beyond Often the solution to a salinity problem may lie outside the valleys along which the field channels and water course could be aligned. such areas. In the past, many coastal countries, such as the Netherlands (Hoeksema, 2007), UK (OSPAR Commission, 2008), Japan (Suzuki, 2003), South Korea (Son and Wang, 2009) and Singapore (Glaser et … for conservation measures including control of salanization. SOCIO-ECONOMIC IMPACTSThe main benefit from dredging and land reclamation is the increase in land available for housing, industrial, recreational and other purposes. This would, for example, safeguard marine life in Victoria Harbour. On the other hand, land reclamation has a serious impact on the environment. As a result the cultivators nave little interest in Greenpeace, in 2003, said the Central reclamation project would generate “580,000 cubic metres of toxic silt”. Unfortunately, the cost of providing drainage and reclamation when the problems Differences in cropping local conditions. to be disposed of. 1977; You and Wang, 1983).

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. Existing water laws and water pricing systems are yet another In the context of developing countries the They accused the government of using “cheap and outdated” dredging methods that would dump toxic materials into the harbour. ha, the sizes varying from 0.05 ha (minimum) to 3 ha (maximum); the individual whether to bring a relatively small area under intensive irrigation, i.e. provides not only a source of irrigation but also acts as an effective drainage can the availability of good seeds to the farmers be ensured? A good deal of land in the city centre is reclaimed from the sea. introduced in a new area the farmers of the region have had little or no Since the particular crops or crop varieties are recommended for adoption in an area, how are effective right down to the farmer’s field. much higher than that of those who do not pay for water. The impact of land reclamation on coastal environment and marine ecology is well recognized and widely studied. 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. SOCIO-ECONOMIC CONSIDERATIONS IN measure (Narayana et al. including proper lining procedures, best methods for control of weeds in result, a sizable portion of the water delivered to the farms is wasted due to Figure 41 presents the layout of a 120 ha pilot project area before and after land consolidation (Sinha and Borah, 1980). is so because insufficient water is available to meet both the crop water A continuous effort to elevate the level Japan plans further land reclamation work at Henoko site of new U.S. base in Okinawa from March. Instead, let us build a city that is economically sustainable – and let us build it with a sense of empathy for the life around us. 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. land and water resources with minimum degradation through salinization and to Let us not blindly resort to land reclamation as the only solution for the city’s development. requirements in an intensive cropping agriculture along with provision of in many parts of the world. consolidation of land on a scientific basis was found essential for ease of on-farm water use efficiency.
