importance of land reclamation

Reclamation was an unsystematic urban expansion measure, which meant that the majority of projects were piecemeal private initiatives which rarely amounted to major infrastructural development policy throughout this period. Therefore, it is important for the Lagos State government, whose goal is to alleviate poverty, to take into cognisance the importance of small scale fisheries in the economic empowerment of artisanal fishing communities. SCMP. Reclaimed land supports many of the city’s landmarks, including Hong Kong Island’s iconic skyline. Because it gives greater stability to gross harvests and to agriculture in general, land reclamation is very important to this branch of the national economy. A field survey conducted in 2019 identified the Lantau dead zones, where oxygen around the sea floor had dipped to 2 milligrams per litre – the threshold for marine life to survive – or lower. With a staggering HKD$624 billion price tag attached, the project aims to house 1.1 million people in an economic and residential hub through the creation of artificial islands covering 1 000 hectares beginning in 2026 or 2027. With a staggering HKD$624 billion price tag attached, the project aims to house 1.1 million people in an economic and residential hub through the creation of artificial islands covering 1 000 hectares beginning in 2026 or 2027.

Should the harbour’s water flow be slowed substantially, its self-cleansing ability may be severely impacted, a situation only aggravated by reclamation projects increasing water turbidity. Ultimately, a comprehensive study examining ocean hydrodynamics, nutrient sources, waste water cycle in the environment and affected ecosystem will be necessary if we are to proceed with any form of land reclamation project. Low oxygen levels can create “dead zones,” which will suffocate marine life and cause others to flee the area. The debris is then used to either extend the coastline or create artificial islands. , a massive land reclamation project of the coast of Lantau Island that will cover 1000 hectares of artificial islands and house over one million people. Since 1973, the government has established nine new towns, complete with private and public housing, transportation infrastructure and commercial centres. positive impact of land reclamation as a mechanism to enhance employment and financial opportunities in agriculture through demand-driven programs, investing in infrastructure for land, soil and water management. In 2018, the Hong Kong government announced Lantau Tomorrow Vision, a massive land reclamation project of the coast of Lantau Island that will cover 1000 hectares of artificial islands and house over one million people. Should the harbour’s water flow be slowed substantially, its self-cleansing ability may be severely impacted, a situation only aggravated by reclamation projects increasing water turbidity. , which mainly criticised the loss of natural and cultural heritage in exchange for minimal benefits for average citizens. Dr. Lam highlighted the unprecedented low numbers of marine species iconic to Hong Kong, including the Chinese white dolphin and the horseshoe crab, species whose habitats have been disrupted by massive land reclamation projects. Early reclamation projects elicited public resistance from waterfront landowners and seaside trading firms with docking rights. In the 1970s, as mainland China began to open itself to foreign capital investment and become the global epicentre of cheap manufacturing, Hong Kong’s firms moved their manufacturing operations to the mainland. On the topic of Hong Kong’s developmental policy taking precedence over conservation efforts, Dr. Lam stated: “Hong Kong likes to adopt the ‘development first, conservation later’ approach. With a worsening dead zone and being surrounded by a discharge point, one could easily make the argument that this is neither eco-friendly or particularly attractive to a potential homeowner. Between 1851 and the early 20th century, most land reclamation projects took place off the northern coast of Hong Kong Island where the British colonial offices were located, primarily between what are now the Kennedy Town and Causeway Bay neighbourhoods. Dr. Lam highlighted the unprecedented low numbers of marine species iconic to Hong Kong, including the Chinese white dolphin and the horseshoe crab, species whose habitats have been disrupted by massive land reclamation projects.

Land reclamation appears to be a mainstay of policy planning for the city in the near future, although its strengths must be balanced with environmental security and minimisation of biodiversity loss. Land reclamation has been an integral component of Hong Kong’s development since the territory’s colonial era, as the practice has permitted the city to accommodate its population and foster economic growth. Land is to be considered the most important aspect of production, especially agricultural production. However, a change to arable land after reclamation would have the opposite effect of increasing the albedo.

More turbulent waters can decrease sunlight and affect marine photosynthesis, and polluting substances can be consumed by smaller fish and increase the food web’s toxicity. In addition to the environmental impact, land reclamation harms efforts to conserve Hong Kong’s cultural heritage. A review of environmental statements and government guidance enabled the compilation of a comprehensive checklist of factors associated with reclamation. A team of researchers (part of Ocean-HK study led by Professor Jianping Gan at The Hong Kong University of Science and Technology) found two seasonal water zones with low oxygen levels near the reclamation site (south and southeast of Lantau Island). The simplest method of land reclamation involves simply filling the area with large amounts of heavy rock and/or cement, then filling with clay and soil until the desired height is reached. This is where the importance of reclamation comes in. Reclamation is done when a piece of land has been used for some specific purpose and is no longer valuable or needed for that purpose. Reclaimed property is often restored to something resembling a natural state, though it can also be repurposed.

The large-scale reclamation plan for the expansion of Central and Wan Chai that began in the 1990s elicited. On the topic of Hong Kong’s developmental policy taking precedence over conservation efforts, Dr. Lam stated: “Hong Kong likes to adopt the ‘development first, conservation later’ approach. As a response, the Hong Kong government forgoed the private enterprise-driven approach to land reclamation, and intervened directly to create new habitable land to accommodate the city’s rapidly growing population. The government’s push of the “Lantau Tomorrow Vision” can also be attributed to its capability to address Hong Kong’s severe housing shortage. Land reclamation has enabled exponential population and economic growth in Hong Kong, and appears to be the developmental instrument of choice for the city’s leadership moving forward. By relieving the extreme conditions that affect the specific region, it gets easier for people to manipulate.Another objective is to combat adverse chemical reactions in the soil. Soil is not only the material on which land organisms live; it also plays important roles in material cycles and energy exchange in terrestrial ecosystems. In response, the government pivoted once more to evaluate the potential for mass land reclamation projects. People have the false feeling that we can preserve habitats and species after development.”. This first land reclamation project extended the shoreline by 15 metres. • For this purpose, the stabilized sludge and other wastes have to meet the following three requirements: Ad t t h i l ti 34 Reclamation Plant Sewage sludge Using Sludge for Land Reclamation • There is a shortage of land reclamation materials in Singapore. Ultimately, a comprehensive study examining ocean hydrodynamics, nutrient sources, waste water cycle in the environment and affected ecosystem will be necessary if we are to proceed with any form of land reclamation project. Focusing on land reclamation in island cities, which tend to be sites of exceptional urban density and thus exceptional spatial competition, I theorise the nature of public space at the intersection of the land and the sea. Reclamation was an unsystematic urban expansion measure, which meant that the majority of projects were piecemeal private initiatives which rarely amounted to major infrastructural development policy throughout this period. Another could involve a costly scheme to remove nutrients from sewage across the city before this waste is discharged. With these concerns in mind, the government should consider some of the following mitigation measures. The new towns of Kwun Tong (built in the 1950s), Tsuen Wan (built in the 1960s), Sha Tin and Tai Po (both built in the 1970s) were all largely reliant on reclamation, and were the first satellite town development projects aimed at accommodating growing population size and opening up new spaces for economic activity. A team of researchers (. Video: Land Reclamation and Innovation in Canada’s Oil Sands. For most citizens, service economy-oriented infrastructural land reclamation projects did not carry the same benefits as the development of new housing and commercial areas. Land reclamation, as a measure of increasing cultivated land area, is being popularized in China in the past decades. In 2018, reclaimed land represented 6% of Hong Kong’s total area and 25% of its developed land.

Based on a public and private housing ratio of 7:3, the remaining land lots can provide quality residential areas to offer the middle class a wider choice in buying their first homes or replacing old ones. A reduction in water volume, combined with urban expansion, would also decrease the harbour’s ability to cool and ventilate surrounding areas, aggravating air pollution and raising urban temperatures. Pumping water out of muddy land or marshes is known as poldering. While a proposed upgrade of a harbour treatment scheme would achieve this desired effect, the plan would not cover large parts of NT or outlying islands like Lantau. In the 1970s, as mainland China began to open itself to foreign capital investment and become the global epicentre of cheap manufacturing, Hong Kong’s firms moved their manufacturing operations to the mainland.

However, this new space and opportunity comes at a significant cost; with its heavy price tag, it will drain the city’s fiscal reserves, which have already been severely depleted by the COVID-19 pandemic. Therefore heavy land reclamation on the coastal areas of the Marmara Sea has been the major environmental concern related to the damage caused to the coastal ecosystems during the last decade. This may have a local effect on climate but the climatic impact on a global scale is negligible. While a proposed upgrade of a harbour treatment scheme would achieve this desired effect, the plan would not cover large parts of NT or outlying islands like Lantau. Water will likely stagnate as the water’s ability to flush out waste water (discharges from the Pearl River Delta and around HK) will weaken, which will lead to stagnant harbours across the artificial islands.
