“Planting in the Public Realm: Projects and Projections”
 
02:06:50
Plant life, long regarded in cities as an amenity, has throughout the twentieth and twenty-first centuries also become an accepted necessity integral to the urban fabric. Yet, there are multiple challenges facing plants and planting design in urban areas. Pollution, climate change, increasingly restricted space, and insufficient or nonexistent public budgets for plants are only some of the factors that make it difficult for vegetation in our cities to survive. Yet numerous new public urban parks have been created, tree planting programs persist, new plant cultivars are developed, spontaneous plant growth is studied, and new planting design paradigms are proposed. In a series of short presentations and a moderated discussion, landscape architects, planting designers, and ecologists will assess the current state of the art in planting the public realm. The event seeks to draw out ideas for how plants can be used in the future design of urbanizing areas to create healthy, sustainable, inclusive, and appealing environments. What is the importance of planting the public realm today, and what are its biggest challenges? What are the roles of landscape architects, designers, ecologists, and plant scientists in accommodating plant life in cities and in areas that are becoming urbanized, and are we beyond botanical xenophobia? Moderated by Sonja Dümpelmann, associate professor of landscape architecture, with Steven Handel, visiting professor in landscape architecture; Noel Kingsbury, writer and garden designer; Norbert Kühn, TU Berlin; Doug Reed MLA ’81, lecturer in landscape; and Matthew Urbanski MLA ’89, associate professor in practice of landscape architecture.

Written language only began at around 3200 BC, but spoken language has existed long ago. Learning by listening is a great way to: - increases imagination and understanding - improves your listening skills - improves your own spoken accent - learn while on the move - reduce eye strain Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone. You can find other Wikipedia audio articles too at: https://www.youtube.com/channel/UCuKfABj2eGyjH3ntPxp4YeQ You can upload your own Wikipedia articles through: https://github.com/nodef/wikipedia-tts "The only true wisdom is in knowing you know nothing." - Socrates SUMMARY ======= Urban ecology is the scientific study of the relation of living organisms with each other and their surroundings in the context of an urban environment. The urban environment refers to environments dominated by high-density residential and commercial buildings, paved surfaces, and other urban-related factors that create a unique landscape dissimilar to most previously studied environments in the field of ecology.Urban ecology is a recent field of study compared to ecology as a whole. The methods and studies of urban ecology are similar to and comprise a subset of ecology. The study of urban ecology carries increasing importance because more than 50% of the world's population today lives in urban areas. At the same time, it is estimated that within the next forty years, two-thirds of the world's population will be living in expanding urban centers. The ecological processes in the urban environment are comparable to those outside the urban context. However, the types of urban habitats and the species that inhabit them are poorly documented. Often, explanations for phenomena examined in the urban setting as well as predicting changes because of urbanization are the center for scientific research.

Humidity
 
18:33
Humidity is the amount of water vapor in the air. Water vapor is the gaseous state of water and is invisible. Humidity indicates the likelihood of precipitation, dew, or fog. Higher humidity reduces the effectiveness of sweating in cooling the body by reducing the rate of evaporation of moisture from the skin. This effect is calculated in a heat index table or humidex, used during summer weather. This video targeted to blind users.
