Nearly one in six Africans is a Nigerian. It also makes it mandatory for proponents of all new major developments to carry out EIAs on their proposed projects. (A) Graph of species population along sampling points (T1, T2 and T3) indicates a decrease in number of species from point T1 (high nutrient content) to point T3 (low nutrient content); and (B) graph of concentration of physico-chemicals along within sites T1, T2 and T3. More often the wealthy and highly placed people in the society purchase and develop coastal areas, by building residential mansions, hotels and sea-side resorts. However, their predicament began when a company known as Nigerian Westminster Dredging and Marine Limited commenced sand filling project at Lagos Lagoon, at the foot of Third Mainland Bridge at Oworonshoki. The method is a natural recovery and a passive method of accomplishing restoration. Oil and gas exploration is the main exploratory activity that occurs in the Niger Delta region. Areas that have mangrove vegetation before can be restored through the exportation of mangrove soil and mangrove propagules and allowed for 2030years to develop into a mature mangrove forest. Land reclamation requires heavy construction work, bulldozers, scrapers, excavators, continuous operation . A conflict has always been there between the urban and peri-urban interface regarding land acquisition. Sand mining is also done with more sophisticated machines, where pumps are used to convey sand from the bottom of the river unto land via long pipes. The plants growing on the sand fill area are between 0.5m and 1.0m tall. Map of Niger Delta Nigeria (circled) bordering the Atlantic Ocean has the biggest mangrove forests in Africa.

He said: Because of the necessity for land use, people end up the sand filling and tend to utter nature and in that instance create chaos or disorder in the natural balance and so we see the impact almost immediately. Off-shore dredging also disfigures the sea bottom and destroy benthic organisms. The project descriptions include shoreline protection and reclamation activities of over 1, 000 hectare of land and construction of a mixed-use development in the city. More than a thousand acres of land was to be created by building a seawall more than 6km in length with. The next kind of management is human management [19].

A combination of these activities leads to the acidification of the river causing fish deaths and physiological and reproductive problems of numerous marine organisms. The direct causes include: (i) land expansion, (ii) construction activities, (iii) land acquisition and (iv) succession (land-forming activities of mangroves). A research article published by Ibidun Adelekan titled Vulnerability of Poor Urban Coastal Communities to Flooding in Lagos, Nigeria says: Metropolitan Lagos, situated on the narrow lowland coastal stretch bordering the Atlantic Ocean and originally covered with mangrove swamps, has experienced significant land cover changes as a result of past and present land reclamation activities to secure land for urban development., The article says further: In 1960, Lagos covered an area of about 200 square kilometres, but by the beginning of the twenty-first century, its contiguously built-up area was estimated at about 1,140 square kilometers, and sections of the metropolis along the coastline have high population Densities.. Permits are issued by DEC for annual terms of up to five years and may be renewed. During canalization, earth moving dredgers are deployed to excavate the benthic soil. Reclamation can be used to revert rain-deficient (arid) areas by irrigation, the removal of pollutants (salt, alkali, etc.) The problem of this action is that the nipa palm forest after being cleared is repossessed by the government for infrastructural developments, which rather than reduce the negative effect worsen the situation of the coast. The promise of accelerating growth, however, is questionable. Sites T1, T2 and T3 are the end, middle and mouth of the sand fill area. The most dominant species found was white mangroves (Laguncularia racemosa) (108) followed by red mangroves (Rhizophora racemosa) (104), black mangroves (Avicennia germinans) (77) and nipa palm (Nypa fruticans) (17). It is noteworthy that Songo International Business District also in South Korea which is reputed to be the largest private development in the country is built on a reclaimed land in the area of Incheon waterfront. These phases include: (i) deforestation of mangrove forest (ii) consolidation of swamp with bulldozers, (iii) pumping of white sand from the sea bottom unto shore, (iv) sand filling of reclaimed land, and (v) construction activity e.g. Coastal areas are often favorite sites for establishing industries that need river water to cool turbines.

The cost of land appreciates and has no depreciative value. The provisions of the EIA Act No. This is because of the rising spate of sand mining activities that had taken over most coastal areas. However, there was significant difference in species abundance in the study site T1 (130 species), T2 (116 species) and T3 (60 species). Shrimp farming in particular has resulted to the conversion of large areas of mangroves. Not surprisingly, the country that is home to the largest population of the region also has by far the largest area under cultivation. Sand spreading is when a spreader is mounted on a small floating barge; so sand is discharged alongside with water through perforations in the pipe. This could lead to the death of soil dwelling organisms. We basically try to establish new habitat type because we cannot establish historic ecosystem. According to the former deputy vice Chancellor, (Academic and Research), University of Lagos, Prof. Babajide Alo, land reclamation without due Environmental Impact Assessment (EIA) could lead to serious environmental degradation.

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. This is because of land expansion activities such as urban development. The dehydration of the intertidal areas cuts off dissolved oxygen and food supply to aquatic species. Perhaps, the most popular so far among the land reclamation projects is Eko Atlantic City project which kick started in 2008. Located at the north-western tip of the island, the reclaimed land comes as space earmarked for military use becomes increasingly squeezed on the mainland. Conversion of coastal environment to terrestrial area through deforestation and solidification to terrestrial environment in the Niger Delta, Nigeria. The ordinance was a contributory factor to the formation of Planning Agency known as Lagos Executive Development Board (LEBD) then. The latter is derived from coastal activities such as oil and gas, shipping, fishing, tourism and commerce. Before reclamation the site is cleared, which leads to the destruction of native plant species within the reclaimed area [3]. Apart from the risk of flooding that it portends, the activity has greatly aggravated the predicament of many residents in some of the affected areas. It is a strategy for protecting or restoring the function, structure and species composition of an ecosystem while providing for its sustainable socioeconomic use. However, in many communities coastal lands are protected traditionally if they have cultural significance to the people [1].

But in the last two months I have not caught a single fish. The system of reclaiming land can be achieved through various methods. The white patch indicates the sand filled area while the green patches indicates mangrove forest that is still standing. Land reclamation impact the coastal environment in several ways (Table 1). Expansion of creeks allow for navigational activities, commerce and construction. Some of the biggest cities in Nigeria are looked at below. Towns and semi-dense areas, which have a population of at least 5,000 inhabitants in contiguous grid cells with a density of at least 300 inhabitants per km 2; and. Surrounding areas of the swamps are usually dredged and sand-filled to enable it to support the mounting of crude oil well head and the laying of pipelines (Figure 5). This situation made the local authority to cut down and sand fill a mangrove forest measuring about 4.2 million m2 in 1984 (Figure 2). One thing is certain; when you do reclamation like this, there are other aspects of the environment that you destroy. Landscape reclamation is used to remediate polluted and devastated area in many parts of the world such as abandoned coal mine, crude oil exploration site and abandoned aquaculture. Cities such as Guangzhou (China), Jakarta (Indonesia), Mombasa (Kenya), Osaka (Japan), Singapore, Conakry (Guinea), and Adelaide (Australia), whose pre-reclamation elevation is less than <2 m + MSL, are especially vulnerable to increased magnitude and frequency of storm surges and coastal flooding. Im a fisherman, how am I supposed to survive, the man lamented. These areas are naturally covered with water during high tides, but are filled with soil and consolidated to prevent tidal flooding during high tide. Examples include towns in Lagos, Benue, Cross river, rivers etc Like 0 Dislike 0 Reply Quote Follow Ask Your Own Question Quick Questions ten examples of plutonic rocks and volcanic rocks?

This method works well for foreshore locations with good seabed soil. Because of the non-use of the palms they had been removed from several locations with the aid of swamp buggies as a means of mitigating their negative environmental effect. Introductory Chapter: Landscape Reclamation as a K Department of Animal and Environmental Biology, University of Port Harcourt, Choba, Nigeria. This is because the adventitious roots of the mangrove forest serve as tidal breaks. Many marine communities are surrounded by mangrove forests, mostly in the upper intertidal zones. In a classical case of land recuperation after landscape reclamation at Eagle Island in the Niger Delta, recruitment occurred through natural process within a space of 13years. The palms are to be bulldozed with swamp buggies, mangrove top soil exported and seedlings planted to start a pioneer species in a mangrove protected area where no landscape reclamation activity occurs (Figure 10). This means they would be the ready pool of labour for construction projects and their tenements will be enhanced by the investment flowing into the site., Allaying the fears of the people, the commissioner said: The Lagos state government, as a responsible entity, pursues a policy of ensuring that Environmental Impact Assessment is done by every individual or corporate body that seeks to embark on projects. The presence of mangroves along the coast stabilizes and reinforces the soil against erosion.

In October 2021, DEC prepared, . It is the returning of lands to an improved state. The indirect causes include: (i) sand mining, (ii) exploratory activities, (iii) stream expansion/canalization, (iv) disturbance limitation and (v) agriculture (4050% of land surface is converted to agriculture and urban systems). Narrating their ordeal to Premium Times last year, the residents whose hope of economic survival has been tampered with, have tales of woe to tell concerning their awful experience. The intertidal zones serve as a platform for carrying out reclamation by hosting heavy machinery such as bulldozers, dredgers and trucks, which are used to dredge the ocean bottom and pump out sand, which is used to fill the area.

Decrease in water level affect intertidal level especially when areas along the shore receive no water supply and become dry. Land in the Niger Delta area is in large demand because of traditional and cultural beliefs attached to the possession of land [1]. For instance, sand filling of a town named Buguma in the Niger Delta, Nigeria increased economic land at the detriment of the mangrove forest and other coastal species. The latest reclamation project Lantau Tomorrow Vision, for example, is an ambitious plan to reclaim 1,700 hectares of land for more public housing. A study found land-reclamation projects shrank the number of mangroves in Tubli Bay, off Bahrain's east coast. Fast-growing cities in the Gulf and Southeast Asia are turning water into real estate at a spectacular pace and scale. But in the Niger Delta landscape reclamation is used to convert coastal areas to terrestrial areas. Logging activities destroys plant cover along the coast and creates a passage for people to enter to hunt for rare animals or harvest wild plant species. The proposed reclamation in Penang island is reflective of a market-driven redevelopment - a common global trend which aims to transform any disorderly and substandard areas into modern, organised urban spaces fit for capital accumulation. Reclamation is carried out by both government and private developers. Similarly, reckless and indiscriminate hunting in opened forest reduces population and thus reduces species diversity, which may lead to extinction of some species. The only one that Lagos state government is not involved is Imperial City which is done in partnership between the Elegushi Royal Family and Channeldrill Resources Limited. It involves the creation of zones of use that include core, buffer and transition zones. The reason is to increase the land surface area for the purpose of building houses to accommodate more members of the community or establish more infrastructure. The dredged soil that is evacuated from the river bottom is dumped on land surface and smothers coastal vegetation such as mangroves.
