Seaweed Farming
Seaweed farming or kelp farming is the practice of cultivating and harvesting seaweed. In its simplest form, it consists of the management of naturally found batches. In its most advanced form, it consists of fully controlling the life cycle of the algae. The top seven most cultivated seaweed taxa are ''Eucheuma'' spp., ''Kappaphycus alvarezii'', '' Gracilaria'' spp., ''Saccharina japonica'', '' Undaria pinnatifida'', '' Pyropia'' spp., and '' Sargassum fusiforme''. ''Eucheuma'' and ''K. alvarezii'' are farmed for carrageenan (a gelling agent); ''Gracilaria'' is farmed for agar; while the rest are farmed for food. The largest seaweed-producing countries are China, Indonesia, and the Philippines. Other notable producers include South Korea, North Korea, Japan, Malaysia, and Zanzibar (Tanzania). Seaweed farming has frequently been developed as an alternative to improve economic conditions and to reduce fishing pressure and overexploited fisheries. Global production of farmed a ...

Eucheuma Farming, Philippines (5211726476)
''Eucheuma'', commonly known as gusô (), is a rhodophyte seaweed that may vary in color (red, brown, and green). ''Eucheuma'' species are used in the production of carrageenan, an ingredient for cosmetics, food processing, and industrial manufacturing, as well as a food source for people in the Philippines and parts of Indonesia and Malaysia. ''Eucheuma cottonii'' – cultivated in the Philippines – is the particular species known as gusô. Other species include ''Betaphycus gelatinae'', ''Eucheuma denticulatum'', and several species of the genus ''Kappaphycus'', including ''K. alvarezii''. Since the mid-1970s, ''Kappaphycus'' and ''Eucheuma'' have been a major source for the expansion of the carrageenan industry. Commercial seaweed farming of gusô (as well as ''Kappaphycus'') was pioneered in the Philippines. Though commercially significant, species of ''Eucheuma'' are difficult to identify without the aid of close scientific examination, as different species may have simila ...

Agar
Agar ( or ), or agar-agar, is a jelly-like substance consisting of polysaccharides obtained from the cell walls of some species of red algae, primarily from ogonori (''Gracilaria'') and "tengusa" (''Gelidiaceae''). As found in nature, agar is a mixture of two components, the linear polysaccharide agarose and a heterogeneous mixture of smaller molecules called agaropectin. It forms the supporting structure in the cell walls of certain species of algae and is released on boiling. These algae are known as agarophytes, belonging to the Rhodophyta (red algae) phylum. The processing of food-grade agar removes the agaropectin, and the commercial product is essentially pure agarose. Agar has been used as an ingredient in desserts throughout Asia and also as a solid substrate to contain culture media for microbiological work. Agar can be used as a laxative; an appetite suppressant; a vegan substitute for gelatin; a thickener for soups; in fruit preserves, ice cream, and other ...

Laminaria
''Laminaria'' is a genus of brown seaweed in the order Laminariales (kelp), comprising 31 species native to the north Atlantic and northern Pacific Oceans. This economically important genus is characterized by long, leathery laminae and relatively large size. Some species are called Devil's apron, due to their shape, or sea colander, due to the perforations present on the lamina. Others are referred to as ''tangle''. ''Laminaria'' form a habitat for many fish and invertebrates. The life cycle of ''Laminaria'' has heteromorphic alternation of generations which differs from '' Fucus''. At meiosis the male and female zoospores are produced separately, then germinate into male and female gametophytes. The female egg matures in the oogonium until the male sperm fertilizes it. Life-Cycle: The most apparent form of ''Laminaria'' is its sporophyte phase, a structure composed of the holdfast, the stipe, and the blades. While it spends its time predominately in the sporophyte phase ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Climate Change Mitigation
Climate change mitigation is action to limit climate change by reducing emissions of greenhouse gases or removing those gases from the atmosphere. The recent rise in global average temperature is mostly caused by emissions from fossil fuels burning (coal, oil, and natural gas). Mitigation can reduce emissions by transitioning to sustainable energy sources, conserving energy, and increasing efficiency. In addition, can be removed from the atmosphere by enlarging forests, restoring wetlands and using other natural and technical processes, which are grouped together under the term of carbon sequestration. Solar energy and wind power have the highest climate change mitigation potential at lowest cost compared to a range of other options. Variable availability of sunshine and wind is addressed by energy storage and improved electrical grids, including long-distance electricity transmission, demand management and diversification of renewables. As low-carbon power is more ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbon Dioxide Removal
Carbon dioxide removal (CDR), also known as negative emissions, is a process in which carbon dioxide gas () is removed from the atmosphere and sequestered for long periods of time. Similarly, greenhouse gas removal (GGR) or negative greenhouse gas emissions is the removal of greenhouse gases (GHGs) from the atmosphere by deliberate human activities, i.e., in addition to the removal that would occur via natural carbon cycle or atmospheric chemistry processes.IPCC, 2021Annex VII: Glossary atthews, J.B.R., V.
