In an attempt to create modern neighborhoods without the need of the defensive system of the town walls, which no longer offered protection in advanced warfare techniques.
The document discusses the concepts and principles of neighborhood planning. It describes Clarence Perry's neighborhood unit model from the early 1900s which centered schools in neighborhoods and used arterial streets to define boundaries while prioritizing walkability. The purpose of neighborhood planning is to enable social interaction, share amenities, and ensure safety. Principles include limiting neighborhood size, using major roads as boundaries, internal street hierarchies, and dedicating 10% of land to open space. Southern Village in Chapel Hill, NC is provided as an example, being a 312-acre mixed-use development with housing, retail, offices, and civic spaces organized around a central green.
Conservation is not just a result of few years but work and dedication of centuries. With every good, there certainly follows bad but focusing on the positives and addressing the bad is what drives us to the future; in this case the future for our past.
Industrial revolution impacts on human settlementsChaitanya Korra
The industrial revolution had significant impacts on human settlement patterns. It led to the growth of cities as factories became the center of economic activity and drew large numbers of workers. This rapid urbanization created overcrowded and unsanitary living conditions in many cities, especially in neighborhoods near factories. New workers' housing, schools, and other infrastructure struggled to keep up with the fast-growing urban populations. While public health and safety improved over time, many 19th century systems are now obsolete. The industrialization process also concentrated pollution and public health issues in urban areas.

This document summarizes a presentation on integrative risk assessment and management for residential recycled water schemes in Australia. It introduces residential recycled water schemes and their objectives to reduce potable water demand, effluent discharge, and stormwater runoff. It then shows that few schemes in Australia have been successful long-term. Through historical analysis and industry surveys, it identifies key risks to schemes' long-term viability like public health concerns, economic challenges, and regulatory issues. The presentation argues current risk assessment and management practices have limitations like poorly defined objectives and an independent approach that does not consider time and context adequately. Improved integrative risk management is needed for resilient recycled water schemes.

In conclusion, the cement and concrete industry has a vital role to play in shaping the future of our planet. By embracing sustainability and innovation, it can pave the way for a greener, more sustainable world for generations to come. Let us seize this opportunity to build a brighter future for all.
- There is a need for alternative and appropriate technologies in construction due to the large housing shortage and constraints on materials and resources. Labor-based construction programs using local materials can help address this need.
- Appropriate technologies should follow principles like energy conservation, using local and renewable materials, and minimizing environmental impact. Waste materials from industries can be used to make building materials.
- Low-cost and appropriate technologies do not compromise on quality or strength while using less capital and resources. They are developed based on local needs and capabilities.
- Research institutions are developing appropriate technologies like stabilized mud blocks, mud plasters, and vaulted roofs that utilize local materials and labor to lower costs.
The document discusses the theme "Engineering Preparedness for Disaster Mitigation" which has been selected for Engineers' Day on September 15th, 2011. It notes that natural disasters have increased in frequency and intensity, causing over 5 million casualties and huge economic losses in the last decade. The recent earthquake and tsunami in Japan demonstrated the devastating impact of natural disasters and highlighted the need for engineering and technical solutions to better prepare for such events. The document advocates applying modern technologies like satellite communication, renewable energy, and robotic systems to disaster mitigation efforts including early warning systems, temporary shelters, search and rescue, and raising public awareness of mitigation techniques.
This document discusses using tourism as a tool for regional sustainable development in the Mediterranean region. It faces challenges like climate change, desertification, and urbanization. Creating new tourist destinations in underdeveloped regions is necessary using new infrastructure like broadband internet, as modern tourists rely on the internet. Tourism is a major global industry, but could help remote areas by developing local culture and ecology. A 2010 feasibility study recommended observing tourism trends, stimulating research and innovation in new regions, and establishing a training network to experiment with technologies like augmented reality to develop sustainable tourism.
This document summarizes a paper on sustainable construction materials and technology in the context of sustainable development. It introduces the authors and defines sustainability in construction as using locally available, energy efficient and durable materials that protect the natural environment throughout a building's lifecycle. It then discusses how sustainable development can be achieved through the adoption of sustainable construction materials and technologies, focusing on five specific sustainable materials.
This document summarizes 5 research articles on construction waste management. The articles discuss challenges like lack of skills, reluctance of customers, and lack of awareness in adopting sustainable practices. They analyze legal aspects that can improve waste management systems and barriers to reuse of construction waste in Australia. One article estimates construction waste volume using computer vision while another studies construction waste management in India and emphasizes the reduce, reuse, recycle approach. A case study from Nigeria discusses the rapid increase in municipal solid waste production and current methods of collection and disposal.

A presentation conducted by Professor Edward J Blakely, Honorary Professor, Urban & disaster recovery expert, United States Studies Centre, University of Sydney.
Presented on Thursday the 3rd of October 2013.
What we term infrastructure today is the built up environment created in the last 100 years to move people and commerce, heat and cool. This infrastructure was created as a buttress against nature. It was built to be solid and immoveable. It also had to be upgraded and repaired in the same places to perform the same functions. Future function were merely linear projections of the past. But the past is no longer prologue. Too much of what we term infrastructure today is not useful for solving today’s problems let along tomorrows. Would we ever create cities on the ocean’s edge, if we knew of sea-level rise? Would we ever create massive non adaptable fixed power stations if we knew fuels would dwindle and centralized systems would be dangerous and unsustainable? We know the answers. But we continue to march backward to the future. In this talk I want to look back to ancient times where cities failed because they were not adaptable and project a future where we will have to create re-generative infrastructure that adapts to its environment and settlement systems that are light on the
environment rather than fixed and heavy. This approach calls for a total re-thinking of urban settlement systems and a new generative infrastructure to support them.

The document discusses concepts related to ensuring a safe, secure, and sustainable energy supply. It introduces the concepts of risk assessment, resilience management, security of supply, sustainability, and multi-criteria decision analysis. It then presents a case study from the EU SECURE project that used these concepts to evaluate policy scenarios according to various environmental, economic, social, and security indicators. The study found that global climate policy scenarios generally performed best, though they were vulnerable to certain shocks like nuclear accidents or carbon capture failures. Overall policies that reduced fossil fuel use and led to greater diversification of energy sources and imports improved sustainability and security.

Some numbers about natural hazards, to show their impact.
The impact of these natural hazards has been very high.
Not only human losses but also economic losses are very high.
Trends in natural hazards:
Graph shows the number of disasters per year and per type, from 1950 to 2015.
> disasters are increasing!
Trends in natural hazards:
Urbanization: urban population is growing fast > growing number of vulnerable people
An enormous volume of capital is expected to flow into urban development in the coming decades, particularly in south Asia and sub Saharan Africa.
Challenge + opportunity: +- 60% of the area expected to be urbanized by 2030, remains to be built
Trends in natural hazards:
Most affected people live in developing countries
From 1970 to 2008 e.g., more than 95% of deaths from disasters caused by natural hazards, were in developing countries.
The number of poor exposed to natural hazards will reach 325 million by 2030.
Summary:
Hazards are increasing
Not only human but also huge economic losses
Due to urbanization, the number of vulnerable people is also increasing
Most affected are people in developing countries
International DRR policy
The SDGs call for safe housing, sustainable urbanization, safeguarding heritage, a holistic disaster risk management and resilient buildings.
Moreover, they state to cooperate more and foster science, technology and innovation capacity-building mechanism.
The UN Plan of Action on DRR calls for cooperation and coordinated, high-quality support.
It aims also to ensure that DRR remains a priority for UN organizations.

Why failure of buildings?
The inability of reinforced concrete to withstand a major earthquake when it is used incorrectly and with substandard building practices could lead to an unprecedented disaster.
If used correctly and under the best conditions, concrete structures, reinforced with steel bars, can withstand earthquakes. The problem is that the methods and raw materials often are not ideal. And once a building is up, the quality of the concrete is nearly impossible to judge.
CASE Turkey:
(At the first Earthquake Safe International Conference, sponsored by UNESCO, Turkey's Ministry of Public Works, and the International Council on Monuments and Sites.)
During the conference, Turkish architects Demet Gulhan and Inci Ozyoruk Guney presented the first hard evidence that people living in modern, reinforced concrete structures died at a much higher rate thanpeople living in older, traditional houses during the Marmara earthquake.In one example from their study, the Sehitler district of Golcuk had a roughly equal number of reinforced concrete and traditional structures. Yet of the 290 deaths, 287 occurred in reinforced concretestructures and only three occurred in traditional-style buildings. Of the 789 traditional buildings, 701 survived the quake undamaged, but of the 814 reinforced concrete buildings, only 550 escaped damage.
Of the buildings that collapsed, only four were traditional buildings, while 60 were made of reinforced concrete."Reinforced concrete frame structures presented a high level of damage due to low-quality concrete, inadequate engineering, incorrect construction techniques, poor detailing, inadequate inspection orobservation of construction, and lax attitudes of authorities in the application of the building code," Gulhan said during her presentation.
Most of Turkey is considered vulnerable to earthquakes. Yet according to Turgut Cansever, one of the conference speakers, "approximately 70 percent of the building stock of Istanbul was built without technicalassistance.“
Turkish architect Hayim Beraha, who was touring the settlement with Langenbach, was more direct. "This will collapse," he said. "These people are from the countryside. And where they came from, they usedto know better. The problem is the perception that living in a modern house is living in a concrete house."

disaster resilient vernacular housing technology depending on region
Since the March 2005 earthquake, the indigenous practices used to construct traditional houses in Nias have been studied and have gained a reputation for their earthquake resistant quality. However, whilst this example of indigenous practice is celebrated, the devastating impact of the March 2005 earthquake on Nias Island, its population and its economy, must not be forgotten. This seems ironic given that Nias Island was at the time and still is home to one of the world’s best example of earthquake resistant architecture. This irony shows us firstly that isolated examples of indigenous practice alone cannot contribute significantly to disaster risk reduction.
Secondly, it demonstrates that as the traditional is given up in favor of the modern, communities can be left exposed to the risk of disasters. Modernization has played a big part in the rapidly disappearing traditional architecture of Nias. The status symbol which is represented by this shift to modern design and lifestyle is adequate reason for most people to choose the less resistant Malayan houses over the traditional wooden structures. Deforestation has exacerbated the situation. The hardwood needed to build traditional houses is in scarce supply. As a consequence many of the methods and techniques used to build traditional houses are slowly being forgotten since concrete and bricks have replaced timber as construction material.
There are many examples of traditional building methods in Pacific islands. Due to the frequency of natural disasters in the region, many building styles demonstrate the traditional Samoan fale tele, which is mounted on a high stone foundation to prevent flooding and storm surges. It has a high dome ceiling to combat humidity and has open sides to allow winds to pass through. Such traditional dwellings incorporate architectural styles that enable them to withstand extreme weather and strong winds. Even in the event of the structure failing, replacement materials are readily available and sustainable, and the collapse generally would not injure the inhabitants. Many of the traditional aspects of vernacular housings in the Pacific have eroded with the introduction of Western building techniques and materials, including corrugated iron and concrete. Construction is often unregulated, and buildings are not built according to proper building standards and codes. This makes the Western-style buildings more vulnerable to environmental hazards and more dangerous to inhabitants.
In Samoa, the builders of houses were also the architects who belonged to an ancient guild of master builders, tufuga fau fale. The Samoan word tufuga denotes the status of master craftspeople or Living Human Treasures. The Post-Disaster Needs assessment following Cyclone Evan that hit Samoa in December 2012 recommended
these skills will enhance the resilience of communities by reinvigorating the positive features of traditional buildings in Samoa. This will be particularly relevant as cyclone
intensity is predicted to increase in the region due to climate change.
The longhouse is considered to be one of the oldest architectural forms in Sarawak and can be found throughout Borneo Island
Known as a “village under one roof,” a longhouse is a type of elevated communal dwelling comprising a series of interconnected apartments arranged linearly. Each apartment is connected to a communal gallery space on the side. On the other side of the apartments are kitchens and bathrooms. Longhouses are traditionally constructed of wood with a thatch roof, but more recently many have tin roofs.
Example:
longhouse burnt. Villagers began building individual temporary homes. Living in individual homes has resulted in a more visible and apparent difference of income between families, a factor which was less visible in the old longhouse.
The longhouse’s communal gallery (ruai) has been lost, resulting in a loss of communication. This weakens the community, hinders development, and gives no opportunity for greeting guests, an important part of Iban custom.
The longhouse is deeply rooted in Iban culture, encompassing many Iban traditions and values in its built form.
Longhouse planning involves a long process of discussions, designing,…
The longhouse stands as a built symbol of community collaboration, economic revitalization and pride that has conquered homelessness.
The Iban are an ethnic group in the province of Sarawak, Malaysian Borneo, that traditionally lives in longhouses consisting of up to 100 family apartments. Communities in their egalitarian society choose their leaders and follow longstanding customs that maintain harmonious relationships between people.
We can learn from vernacular architecture
What can we learn from vernacular architecture?
Examples
In July 2015, Ban began a project to rebuild homes for the victims of Nepal Earthquake. The structures of the homes are wood framing for flexibility and built fully with brick walls: quick and easy to build. Also, the Nepali community can use them for many other purposes, such as schools etc.
In his architecture, Shigeru Ban uses many themes and methods found in traditional Japanese architecture (such as shōji).
Pakistan's first female architect
One of the most successful providers of disaster relief shelters in the world. She has built more than 36,000 houses for victims of floods and earthquakes in Pakistan since 2010
using techniques from vernacular architecture (lime, mud bricks)
lime mortar = limestone + sand
used in 14th century necropolis ‘Makli’
= waterproof
RE-AINBOW: 2015
= health station, public restrooms and ancillary areas, classroom, art performance theater, meeting place, sports fitness center, refreshment tent, areas for physical training such as volleyball, badminton, long jump, and other outdoor activities
Re-use of waste items and efficient use of energy. A collection and reuse of a variety of old/ broken construction materials such as scaffolding steel pipes, sheet metals, bricks, ashlars, bathroom ware, tables and chairs,…with the local people’s involvement in manual construction are proposed in order to create a structure secure enough to stand heavy storms. Ventilation and natural lighting are also dealt with efficiently. Solar energy is converted into electricity for lighting facilities and heating water for daily use. Rain water and used water are also utilized.
Elevated building
Frame is designed to offer a degree of flexibility that could help to absorb vibrations in future earthquakes.
circulation of natural air, and the penetration of natural light into the building
Holistic approach is important.
To show importance of holistic approach, here examples if this approach has not been followed.
‘Modern’ concrete frame building didn’t take into account environment, local building materials, local capacity, cultural aspects,…
Prototype house layout was repeated in its thousands by different contractors on different sites, using the same technology of reinforced concrete.
Cultural dimension of reconstruction overlooked.
Result: total rejection of the new settlements by local people.
Houses altered, extended or changed by locals.
Consequence: most of the subsequent additions to houses did not have earthquake-safe features because of the inability to follow the introduced technology.
Masonry introduced by the Dutch (19th century), copied from Europe. The strength of mortar is dependent on moisture. So buildings were annually white washed with porous mix so that rain could penetrate. BUT: introduction of new building materials > acrylic, weather shield paints. So rain cannot penetrate and mortar became brittle.
Kathmandu: during the last half-century, huge transformation:
Large amounts of money have flowed into the country from the developed world under the premise of improving the well-being of what has been viewed as an ‘underdeveloped’ country, , but much of this ‘development’ has been destructive of both the environment and the culture of the place.
