Bay Of Jakarta
Jakarta Bay ( id, Teluk Jakarta) is a bay north of North Jakarta city. The Thousand Islands are located in Jakarta Bay. 13 rivers flow into the bay. The majority of the bay's coastal communities consist of people living below the poverty line, in conditions of poor sanitation. Nutrient inputs from agricultural runoff, industrial pollution, and wastewater have led to eutrophication, which in turn led to changes in the area's biodiversity. Harmful algal blooms An algal bloom or algae bloom is a rapid increase or accumulation in the population of algae in freshwater or marine water systems. It is often recognized by the discoloration in the water from the algae's pigments. The term ''algae'' encompa ... have been observed.

North Jakarta
North Jakarta ( id, Jakarta Utara; bew, Jakarte Belilir) is one of the five administrative cities (''kota administrasi'') which form Special Capital Region of Jakarta, Indonesia. North Jakarta is not self-governed and does not have a city council, hence it is not classified as a proper municipality. It contains the entire coastal area within the Jakarta Special District. In North Jakarta, an area at the estuary of Ciliwung river was the main port for the kingdom of Tarumanegara, which later grew to become Jakarta. Many historic sites and artefacts of Jakarta can be found in North Jakarta. Both ports of Tanjung Priok and historic Sunda Kelapa are located in the city. The city, which covers an area of 139.99 km2, had 1,645,659 inhabitants at the 2010 census and 1,778,981 at the 2020 census. It has its administrative centre in Tanjung Priok. North Jakarta contains some of Jakarta's original natural mangrove forests. As the city has developed, some of this mangrove forest was co ...

Thousand Islands (Indonesia)
The Thousand Islands (Indonesian: ''Kepulauan Seribu'') are a chain of islands to the north of Jakarta's coast. It forms the only regency of Jakarta, the capital of Indonesia. It consists of a string of 342 islandsSK Gubernur KDKI No. 1986/2000 stretching north into the Java Sea at West Jakarta Bay and in fact north of Banten Province. Pramuka Island is the regency seat. A decree states that 36 islands may be used for recreation.SK Gubernur KDKI No. 1814/198 Of these, only 13 islands are fully developed: 11 islands are homes to resorts and two islands are historic parks. Twenty-three are privately owned and are not open to the public. The rest of the islands are either uninhabited or support a fishing village. History The modern history of the Thousand Islands begins with its role in the defenses of the city of Batavia for the Dutch East India Company ( nl, Vereenigde Oostindische Compagnie, abbreviated VOC) and the Dutch colonial empire. Before the arrival of the Dutch, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as Stream#Creek, creek, Stream#Brook, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to Geographical feature, geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "Burn (landform), burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from Precipitation (meteorology), precipitation through a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poverty Threshold
The poverty threshold, poverty limit, poverty line or breadline is the minimum level of income deemed adequate in a particular country. The poverty line is usually calculated by estimating the total cost of one year's worth of necessities for the average adult.Poverty Lines – Martin Ravallion, in The New Palgrave Dictionary of Economics, 2nd Edition, London: Palgrave Macmillan The cost of housing, such as the rent for an apartment, usually makes up the largest proportion of this estimate, so economists track the real estate market and other housing cost indicators as a major influence on the poverty line. Individual factors are often used to account for various circumstances, such as whether one is a parent, elderly, a child, married, etc. The poverty threshold may be adjusted annually. In practice, like the definition of poverty, the official or common understanding of the poverty line is significantly higher in developed countries than in developing countries. In October 201 ...

Agricultural Pollution
Agricultural pollution refers to biotic and abiotic byproducts of farming practices that result in contamination or degradation of the environment and surrounding ecosystems, and/or cause injury to humans and their economic interests. The pollution may come from a variety of sources, ranging from point source water pollution (from a single discharge point) to more diffuse, landscape-level causes, also known as non-point source pollution and air pollution. Once in the environment these pollutants can have both direct effects in surrounding ecosystems, i.e. killing local wildlife or contaminating drinking water, and downstream effects such as dead zones caused by agricultural runoff is concentrated in large water bodies. Management practices, or ignorance of them, play a crucial role in the amount and impact of these pollutants. Management techniques range from animal management and housing to the spread of pesticides and fertilizers in global agricultural practices. Bad man ...

Eutrophication
Eutrophication is the process by which an entire body of water, or parts of it, becomes progressively enriched with minerals and nutrients, particularly nitrogen and phosphorus. It has also been defined as "nutrient-induced increase in phytoplankton productivity". Water bodies with very low nutrient levels are termed oligotrophic and those with moderate nutrient levels are termed mesotrophic. Advanced eutrophication may also be referred to as dystrophic and hypertrophic conditions. Eutrophication can affect freshwater or salt water systems. In freshwater ecosystems it is almost always caused by excess phosphorus. In coastal waters on the other hand, the main contributing nutrient is more likely to be nitrogen, or nitrogen and phosphorus together. This depends on the location and other factors. When occurring naturally, eutrophication is a very slow process in which nutrients, especially phosphorus compounds and organic matter, accumulate in water bodies. These nutrients deriv ...

Algal Blooms
An algal bloom or algae bloom is a rapid increase or accumulation in the population of algae in freshwater or marine water systems. It is often recognized by the discoloration in the water from the algae's pigments. The term ''algae'' encompasses many types of aquatic photosynthetic organisms, both macroscopic multicellular organisms like seaweed and microscopic unicellular organisms like cyanobacteria. ''Algal bloom'' commonly refers to the rapid growth of microscopic unicellular algae, not macroscopic algae. An example of a macroscopic algal bloom is a kelp forest. Algal blooms are the result of a nutrient, like nitrogen or phosphorus from various sources (for example fertilizer runoff or other forms of nutrient pollution), entering the aquatic system and causing excessive growth of algae. An algal bloom affects the whole ecosystem. Consequences range from the benign feeding of higher trophic levels to more harmful effects like blocking sunlight from reaching other or ...

Bays Of Indonesia
A bay is a recessed, coastal body of water that directly connects to a larger main body of water, such as an ocean, a lake, or another bay. A large bay is usually called a gulf, sea, sound, or bight. A cove is a small, circular bay with a narrow entrance. A fjord is an elongated bay formed by glacial action. A bay can be the estuary of a river, such as the Chesapeake Bay, an estuary of the Susquehanna River. Bays may also be nested within each other; for example, James Bay is an arm of Hudson Bay in northeastern Canada. Some large bays, such as the Bay of Bengal and Hudson Bay, have varied marine geology. The land surrounding a bay often reduces the strength of winds and blocks waves. Bays may have as wide a variety of shoreline characteristics as other shorelines. In some cases, bays have beaches, which "are usually characterized by a steep upper foreshore with a broad, flat fronting terrace".Maurice Schwartz, ''Encyclopedia of Coastal Science'' (2006), p. 129.
