Rivers Of New Zealand
The rivers of New Zealand are used for a variety of purposes and face a number of environmental issues. In the North Island's hill country the rivers are deep, fast flowing and most are unnavigable. Many of the rivers in the South Island are braided rivers. The navigable rivers were used for mass transport in the early history of New Zealand. Statistics The longest river in New Zealand is the Waikato River with a length of . The largest river by volume is the Clutha River / Mata-Au with a mean discharge of . The shortest river is claimed to be the Tūranganui River in Gisborne at long. Some of the rivers, especially those with wide flood plains and stop banks, have long road bridges spanning them. The Rakaia River is crossed by Rakaia Bridge, the longest bridge in New Zealand at . The third longest bridge is the Whirokino Trestle Bridge on State Highway 1 crossing the Manawatū River. Over of rivers have been mapped in New Zealand. Uses Before colonisation, Māori fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Māori People
The Māori (, ) are the indigenous Polynesian people of mainland New Zealand (). Māori originated with settlers from East Polynesia, who arrived in New Zealand in several waves of canoe voyages between roughly 1320 and 1350. Over several centuries in isolation, these settlers developed their own distinctive culture, whose language, mythology, crafts, and performing arts evolved independently from those of other eastern Polynesian cultures. Some early Māori moved to the Chatham Islands, where their descendants became New Zealand's other indigenous Polynesian ethnic group, the Moriori. Initial contact between Māori and Europeans, starting in the 18th century, ranged from beneficial trade to lethal violence; Māori actively adopted many technologies from the newcomers. With the signing of the Treaty of Waitangi in 1840, the two cultures coexisted for a generation. Rising tensions over disputed land sales led to conflict in the 1860s, and massive land confiscations, to which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
West Coast, New Zealand
The West Coast ( mi, Te Tai Poutini, lit=The Coast of Poutini, the Taniwha) is a regions of New Zealand, region of New Zealand on the west coast of the South Island that is administered by the West Coast Regional Council, and is known co-officially as Te Tai Poutini. It comprises the Territorial authorities of New Zealand, territorial authorities of Buller District, Grey District and Westland District. The principal towns are Westport, New Zealand, Westport, Greymouth and Hokitika. The region, one of the more remote areas of the country, is also the most sparsely populated. With a population of just 32,000 people, Te Tai Poutini is the least populous region in New Zealand, and it is the only region where the population is declining. The region has a rich and important history. The land itself is ancient, stretching back to the Carboniferous period; this is evident by the amount of carboniferous materials naturally found there, especially coal. First settled by Ngāi Tahu, Kāi T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecology
Ecology () is the study of the relationships between living organisms, including humans, and their physical environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere level. Ecology overlaps with the closely related sciences of biogeography, evolutionary biology, genetics, ethology, and natural history. Ecology is a branch of biology, and it is not synonymous with environmentalism. Among other things, ecology is the study of: * The abundance, biomass, and distribution of organisms in the context of the environment * Life processes, antifragility, interactions, and adaptations * The movement of materials and energy through living communities * The successional development of ecosystems * Cooperation, competition, and predation within and between species * Patterns of biodiversity and its effect on ecosystem processes Ecology has practical applications in conservation biology, wetland management, natural resource managemen ...

Acid Mine Drainage
Acid mine drainage, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) is the outflow of acidic water from metal mines or coal mines. Acid rock drainage occurs naturally within some environments as part of the rock weathering process but is exacerbated by large-scale earth disturbances characteristic of mining and other large construction activities, usually within rocks containing an abundance of sulfide minerals. Areas where the earth has been disturbed (e.g. construction sites, subdivisions, and transportation corridors) may create acid rock drainage. In many localities, the liquid that drains from coal stocks, coal handling facilities, coal washeries, and coal waste tips can be highly acidic, and in such cases it is treated as acid rock drainage. This liquid often contains highly toxic metals, such as copper or iron. These, combined with reduced pH, have a detrimental impact on the streams aquatic environments. The same type of chemical reactions and pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dairy Farming
Dairy farming is a class of agriculture for long-term production of milk, which is processed (either on the farm or at a dairy plant, either of which may be called a dairy A dairy is a business enterprise established for the harvesting or processing (or both) of animal milk – mostly from cows or buffaloes, but also from goats, sheep, horses, or camels – for human consumption. A dairy is typically located on ...) for eventual sale of a dairy product. Dairy farming has a history that goes back to the early Neolithic era, around the seventh millennium BC, in many regions of Europe and Africa. Before the 20th century, milking was done by hand on small farms. Beginning in the early 20th century, milking was done in large scale dairy farms with innovations including Rotary milking parlor, rotary parlors, the milking pipeline, and Automatic milking, automatic milking systems that were commercially developed in the early 1990s. Milk preservation methods have improved starti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Resource Management Act 1991
The Resource Management Act (RMA) passed in 1991 in New Zealand is a significant, and at times, controversial Act of Parliament. The RMA promotes the sustainable management of natural and physical resources such as land, air and water. New Zealand's Ministry for the Environment describes the RMA as New Zealand's principal legislation for environmental management. The RMA and the decisions made under it by district and regional councils and in courts affect both individuals and businesses in large numbers, and often in very tangible ways. The Act has variously been attacked for being ineffective in managing adverse environmental effects, or overly time-consuming and expensive and concerned with bureaucratic restrictions on legitimate economic activities. In February 2021, the Government confirmed that the RMA is to be replaced by three separate acts. These will be the Natural and Built Environment Bill (NBA), the Strategic Planning Bill (SPA), and the Climate Change Adaptat ...

Non-point Source
Nonpoint source (NPS) pollution refers to diffuse contamination (or pollution) of water or air that does not originate from a single discrete source. This type of pollution is often the cumulative effect of small amounts of contaminants gathered from a large area. It is in contrast to point source pollution which results from a single source. Nonpoint source pollution generally results from land runoff, precipitation, atmospheric deposition, drainage, seepage, or hydrological modification (rainfall and snowmelt) where tracing pollution back to a single source is difficult. Nonpoint source water pollution affects a water body from sources such as polluted runoff from agricultural areas draining into a river, or wind-borne debris blowing out to sea. Nonpoint source air pollution affects air quality, from sources such as smokestacks or car tailpipes. Although these pollutants have originated from a point source, the long-range transport ability and multiple sources of the pollutant ...

Point Source
A point source is a single identifiable ''localised'' source of something. A point source has negligible extent, distinguishing it from other source geometries. Sources are called point sources because in mathematical modeling, these sources can usually be approximated as a mathematical point to simplify analysis. The actual source need not be physically small, if its size is negligible relative to other length scales in the problem. For example, in astronomy, stars are routinely treated as point sources, even though they are in actuality much larger than the Earth. In three dimensions, the density of something leaving a point source decreases in proportion to the inverse square of the distance from the source, if the distribution is isotropic, and there is no absorption or other loss. Mathematics In mathematics, a point source is a singularity from which flux or flow is emanating. Although singularities such as this do not exist in the observable universe, mathematical po ...

Hydroelectric Power In New Zealand
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Bungy Jumping
Bungee jumping (), also spelled bungy jumping, is an activity that involves a person jumping from a great height while connected to a large elastic cord. The launching pad is usually erected on a tall structure such as a building or crane, a bridge across a deep ravine, or on a natural geographic feature such as a cliff. It is also possible to jump from a type of aircraft that has the ability to hover above the ground, such as a hot-air-balloon or helicopter. The thrill comes from the free-falling and the rebound. When the person jumps, the cord stretches and the jumper flies upwards again as the cord recoils, and continues to oscillate up and down until all the kinetic energy is dissipated. Early tethered jumping The land diving ( Sa: ') of Pentecost Island in Vanuatu is an ancient ritual in which young men jump from tall wooden platforms with vines tied to their ankles as a test of their courage and passage into manhood.
