Shifting Baselines
A shifting baseline (also known as a sliding baseline) is a type of change to how a system is measured, usually against previous reference points (baselines), which themselves may represent significant changes from an even earlier state of the system. The concept arose in landscape architect Ian McHarg's 1969 manifesto ''Design With Nature'' in which the modern landscape is compared to that on which ancient people once lived. The concept was then considered by the fisheries scientist Daniel Pauly in his paper "Anecdotes and the shifting baseline syndrome of fisheries". Pauly developed the concept in reference to fisheries management where fisheries scientists sometimes fail to identify the correct " baseline" population size (e.g. how abundant a fish species population was ''before'' human exploitation) and thus work with a ''shifted baseline''. He describes the way that radically depleted fisheries were evaluated by experts who used the state of the fishery at the start of their ...

Ian McHarg
Ian L. McHarg (20 November 1920 – 5 March 2001) was a Scottish landscape architect and writer on regional planning using natural systems. McHarg was one of the most influential persons in the environmental movement who brought environmental concerns into broad public awareness and ecological planning methods into the mainstream of landscape architecture, city planning and public policy. He was the founder of the department of landscape architecture at the University of Pennsylvania in the United States. His 1969 book ''Design with Nature'' pioneered the concept of ecological planning. It continues to be one of the most widely celebrated books on landscape architecture and land-use planning. In this book, he set forth the basic concepts that were to develop later in geographic information systems. Biography Formative years His father was a manager and later a salesman in the industrial city of Glasgow, Scotland. McHarg showed an early talent for drawing and was advised to consid ...

Los Angeles Times
The ''Los Angeles Times'' (abbreviated as ''LA Times'') is a daily newspaper that started publishing in Los Angeles in 1881. Based in the LA-adjacent suburb of El Segundo since 2018, it is the sixth-largest newspaper by circulation in the United States. The publication has won more than 40 Pulitzer Prizes. It is owned by Patrick Soon-Shiong and published by the Times Mirror Company. The newspaper’s coverage emphasizes California and especially Southern California stories. In the 19th century, the paper developed a reputation for civic boosterism and opposition to labor unions, the latter of which led to the bombing of its headquarters in 1910. The paper's profile grew substantially in the 1960s under publisher Otis Chandler, who adopted a more national focus. In recent decades the paper's readership has declined, and it has been beset by a series of ownership changes, staff reductions, and other controversies. In January 2018, the paper's staff voted to unionize and fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Measurement
Measurement is the quantification of attributes of an object or event, which can be used to compare with other objects or events. In other words, measurement is a process of determining how large or small a physical quantity is as compared to a basic reference quantity of the same kind. The scope and application of measurement are dependent on the context and discipline. In natural sciences and engineering, measurements do not apply to nominal properties of objects or events, which is consistent with the guidelines of the ''International vocabulary of metrology'' published by the International Bureau of Weights and Measures. However, in other fields such as statistics as well as the social and behavioural sciences, measurements can have multiple levels, which would include nominal, ordinal, interval and ratio scales. Measurement is a cornerstone of trade, science, technology and quantitative research in many disciplines. Historically, many measurement systems existed f ...

Mongabay
Mongabay (mongabay.com) is a conservation news web portal that reports on environmental science, energy, and green design, and features extensive information on tropical rainforests, including pictures and deforestation statistics for countries of the world. It was founded in 1999 by economist Rhett Ayers Butler in order to increase "interest in and appreciation of wildlands and wildlife, while examining the impact of emerging local and global trends in technology, economics, and finance on conservation and development". In recent years, to complement its US-based team, Mongabay has opened bureaus in Indonesia, Latin America, and India, reporting daily in Indonesian, Spanish, and English respectively. Mongabay's reporting is available in nine languages. History In an interview with Conjour, Butler said his passion for rainforests drove him to start Mongabay: "I was intrigued by the complexity of these ecosystems and how every species seemed to play a part. As I became more pass ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Around Us (organization)
The Sea Around Us is an international research initiative and a member of the Global Fisheries Cluster at the University of British Columbia. The Sea Around Us assesses the impact of fisheries on the marine ecosystems of the world and offers mitigating solutions to a range of stakeholders. To achieve this, the Sea Around Us presents fisheries and fisheries-related data at spatial scales that have ecological and policy relevance, such as by Exclusive Economic Zones, High Seas areas, or Large Marine Ecosystems. All spatialized data are visualized either graphically or mapped, and all data can be downloaded. Global fisheries catches from 1950 to the present are available, under explicit consideration of coral reefs, seamounts, estuaries and other critical habitats of fish and marine invertebrates. The data presented, which are all freely available, are meant to support studies of global fisheries trends and the development of sustainable, ecosystem-based fisheries policies. In the ea ...

Flynn Effect
The Flynn effect is the substantial and long-sustained increase in both fluid and crystallized intelligence test scores that were measured in many parts of the world over the 20th century. When intelligence quotient (IQ) tests are initially standardized using a sample of test-takers, by convention the average of the test results is set to 100 and their standard deviation is set to 15 or 16 IQ points. When IQ tests are revised, they are again standardized using a new sample of test-takers, usually born more recently than the first; the average result is set to 100. When the new test subjects take the older tests, in almost every case their average scores are significantly above 100. Test score increases have been continuous and approximately linear from the earliest years of testing to the present. For example, a study published in the year 2009 found that British children's average scores on the Raven's Progressive Matrices test rose by 14 IQ points from 1942 to 2008. Similar g ...

Public Service Announcements
A public service announcement (PSA) is a message in the public interest disseminated by the media without charge to raise public awareness and change behavior. In the UK, they are generally called a public information film (PIF); in Hong Kong, they are known as an announcement in the public interest (API). History The earliest public service announcements (in the form of moving pictures) were made before and during the Second World War years in both the UK and the US. In the UK, amateur actor Richard Massingham set up Public Relationship Films Ltd in 1938 as a specialist agency for producing short educational films for the public. In the films, he typically played a bumbling character who was slightly more stupid than average and often explained the message of the film by demonstrating the risks if it was ignored. The films covered topics such as how to cross the road, how to prevent the spread of diseases, how to swim, and how to drive without causing the road to be unsafe fo ...

Nature Conservation
Nature conservation is the moral philosophy and conservation movement focused on protecting species from extinction, maintaining and restoring habitats, enhancing ecosystem services, and protecting biological diversity. A range of values underlie conservation, which can be guided by biocentrism, anthropocentrism, ecocentrism, and sentientism, environmental ideologies that inform ecocultural practices and identities. There has recently been a movement towards evidence-based conservation which calls for greater use of scientific evidence to improve the effectiveness of conservation efforts. As of 2018 15% of land and 7.3% of the oceans were protected. Many environmentalists set a target of protecting 30% of land and marine territory by 2030. In 2021, 16.64% of land and 7.9% of the oceans were protected. The 2022 IPCC report on climate impacts and adaptation, underlines the need to conserve 30% to 50% of the Earth's land, freshwater and ocean areas – echoing the 30% goal of th ...
