Abstract

When disasters strike, people often need quick housing solutions to help them transition from emergency situations back to their normal lives Temporary shelters play a crucial role in providing these solutions These shelters are designed to be lightweight, transportable, and easy to assemble, making them ideal for use in disaster situations. They provide displaced individuals and families with a safe, secure space to sleep, eat, and live while they work to rebuild their lives Temporary shelters may be made from a variety of materials, ranging from wood and metal to plastic and canvas Their design often focuses on providing basic amenities such as shelter, warmth, and privacy while also ensuring durability and sustainability in the long term Overall, temporary shelters are an essential part of disaster relief efforts, helping people to maintain a sense of normalcy and stability during times of crisis

After a disaster, it can take a considerable amount of time for everyone to stabilize, especially if the disaster was severe and caused the collapse of buildings, as seen in the Gujarat earthquake of 2001 Providing temporary shelters becomes crucial in such situations so that people have a stable place to stay while the process of permanent housing construction is underway Earlier, people used to make temporary shelters using whatever materials they could find, but this often led to problems such as leaks during rains and lack of space. However, with advancements in technology and construction materials, it is now possible to provide high-quality temporary shelters in a short period These shelters are designed to be safe, comfortable, and easy to assemble in a short amount of time, enabling people to return to a sense of normalcy sooner. This dissertation will explore the different technologies and construction materials available and how they can be effectively utilized for the rapid provision of temporary shelters in post-disaster situations

Introduction 1.1Backgroundstudy

In the aftermath of a disaster, whetheritbeanaturalcalamitylikeanearthquake,flood,orhurricane,ora human-made crisis such as armed conflict, one of the most pressing challenges faced by affected communities is the need for immediate and suitable shelter. Disasters often result in the displacement of individuals and communities, leaving them vulnerable and in need of safe and secure housing solutions. Post-disaster temporary shelters play a critical role in addressing these urgent needs and providing a semblance of stability during the recovery process, However, the context surrounding post-disaster temporary shelter presents several complex problems that need to be addressed effectively These challenges include the scale and magnitude of displacement, limited resources and disrupted infrastructure, time sensitivity, safety and resilience considerations, cultural and social factors, and the need for long-term sustainability The scale and magnitude of displacement are often immense in the wake of a disaster. Entire communities or even regionscanbeuprooted,leadingtoamassivedemandfor temporary shelter solutions. The challenge lies in providing immediate housing to a large number of

people in a timely manner.Limitedresourcesanddisruptedinfrastructurefurthercomplicatetheprovision of post-disaster temporary shelter. Disasters often lead to the destruction or damage of critical infrastructure, including transportation networks, utilities, and communication systems This limits the availability and accessibility of resources necessary for temporary shelter construction. Delivering construction materials, skilled labor, andsupportservicestoremoteorinaccessibledisaster-affectedareas becomesalogisticalchallenge

Time sensitivity is another significant factor in post-disaster temporary shelter Immediate response and swift action are crucial to ensure the safety, well-being, and dignity of theaffectedpopulation Delaysin providing shelter can exacerbate the suffering and increase the risks faced by displaced individuals and communities However, constructing temporary shelters withinashorttimeframecanbechallengingdue tologisticalconstraints,resourcelimitations,andtheneedforthoroughplanninganddesign. Safety and resilience are paramount in temporary shelter solutions. Disasters often leave affected areas prone to environmental and physical hazards, such as extreme weather conditions, seismic activity, flood-prone regions, or conflict zones. Temporary shelters must be designed to withstand these challenges, ensuring the safety and well-being of occupants Resilience is equally important, as the shelters should be able to withstand aftershocks or secondary disasters, offering alevelofprotectionand stabilityforthedisplacedpopulations.

Cultural and social considerations play a crucial role in post-disaster temporary shelter. Communities affected by disasters have diverse cultural backgrounds, social norms, and demographic characteristics. Temporary shelter solutions should be sensitive to these factors, providing spaces that respect cultural practices, gender-specific needs, privacy requirements, and communal living arrangements. Failure to address these considerations can lead to the marginalization or exclusion of certain groups within the affectedpopulation

Additionally, long-term sustainability is a crucial aspect to consider in post-disaster temporary shelter. While thesesheltersareintendedtobetemporary,theyneedtobesustainableandsupportthetransitionto permanent housing solutions Sustainable materials, design principles, and community engagement are vital for minimizing the environmental impact, ensuring the efficient use of resources, and fostering communityresilienceinthefaceoffuturedisasters

Addressing the complex problem context in post-disaster temporary shelter requires a comprehensive understanding of the specific challenges faced in each disaster scenario It necessitates coordination among various stakeholders, including humanitarian organizations, government agencies, local communities, and experts in architecture, engineering, and disaster management By acknowledging and proactively addressing these challenges, it becomes possible to develop effective and context-specific solutionsthatprovidesafe,dignified,andsustainabletemporaryshelterfortheaffectedpopulations.

2.1Whatispostdisaster?

Post disaster is a term that referstotheperiodafteradisasterhasoccurred,whentheaffectedcommunity tries to recover from the impacts and losses caused by the disaster A disaster is a sudden and extreme event that disrupts the normal functioning of a society or an ecosystem and causes human, material, economic orenvironmentaldamagesthatexceedthecopingcapacityoftheaffectedcommunity Disasters canbenaturalorman-made,andtheycanhavedifferenttypes,scalesanddurations

The post disaster period can be divided into three overlapping phases: response, recovery and reconstruction The response phase involves the immediate actions taken to save lives, protect property and provide relief to the survivors of the disaster. The response phase usuallylastsfromafewhourstoa fewdaysafterthedisaster.Therecoveryphaseinvolvestherestorationofessentialservicesandfunctions, such as water, electricity, health, education and communication The recovery phase also aims to reduce the vulnerability and enhance the resilience of the affected community to future disasters.

2.2 Theroleofshelter

Shelter is essential for people’s safety, security and protection during and after a disaster People may need to find shelter in different places, such as their own homes, other people’s homes, vehicles, public sheltersortemporaryshelters,dependingonthesituationandavailability.Shelterismorethanjustaplace to sleep or rest It also provides a sense of security, personal safety and protection from poor weather conditions, a place to store personal belongings and valuables, and access to food, water and medical treatmentfortheaffectedcommunitycomposedoffamiliesandindividuals

Shelters have different roles and forms depending on the disaster timeline Before a disaster strikes, a shelter is a safe place to stay. These shelters can be one’s own home, a public emergency shelter, or another person’s home.

2.3Afteradisasterspontaneoussheltersandprovidedshelters

There are numerous examples of spontaneous shelters organized by disaster survivors and theirrelatives and friends These examples range from purchasing building materials and services after receiving remittance gifts or loans from relatives or friends to staying with host families or in mass shelters to constructing improvised shelters by disaster survivors themselves. Some affected families or individuals can temporarily stay with familymembersorfriendsifthedisasterhasimpactedtheirhomes Thisoption allows for a quicker response before emergency agencies arrive and long after they leave. This also reduces the need for emergency accommodations However, other families and individuals do not have that option available Therefore, they stay in their damaged homes or try to repair them as a means of survival and safety before receiving emergency aid. Ian Davis and David Alexander have observed an astonishing array of ingenuity by disaster survivors as they improvise shelters and reconstruct their dwellings, often using debris theyhavesalvaged.Inaddition,survivorsdosotomanagetheirownshelter needs.

While there are spontaneous shelter options, there are also provided shelters The first option is hotel accommodations, which may be convenient if sufficient capacity isavailable.However,thisoptionisthe most expensive and may be far from one’s previous residence or workplace The second option is caravans, mobile homes, or containers For example, Japanese architect Shigeru Ban designed blocks of three-story container housing in Onagawa in Miyagi Prefecture, Japan, following the 2011 Tohoku earthquake and tsunami Shipping containers were convertedtoprovidetemporaryaccommodationswith approximately 189apartmentsinthesixthree-storyandthreetwo-storyapartmentblocks Theseprovided shelters offer a more structured and organized approach to temporary housing,providingindividualsand familieswithasaferandmorestablelivingenvironmentduringthepost-disasterrecoveryperiod

Two additional options for post-disaster shelter include providing plastic sheeting, materials, and tools

Local governments often leave these supplies on the sides of roads, allowing the community to collect them free of charge. This enables individuals to make repairs to their homes or construct improvised shelters using their creativity and skills Despite the damage caused by the catastrophic disaster, these resources empower displaced communities to create livable conditions and restore a sense ofshelterand security.

2.5 Livingspacerequirment

● Living space is a fundamental human need and right, providing a place for individuals and familiestodwell,feelsafe,andcarryoutessentialdomesticactivities.

● Adequate living space should cater to daily activities such as sleeping, food preparation, eating, washing,dressing,andstorageoffoodandpossessions.

● Living spaces should be designed in a manner that respects and aligns with local cultural and socialnorms

● Privacy and separation between sexes, age groups, and families should be ensured within the livingspace.

● Living spaces contribute toindividuals'overallwell-beingbyprovidingaconduciveenvironment thatsupportstheirphysical,emotional,andsocialneeds.

● Accesstosuitablelivingspacespromotesdignityandqualityoflifeforindividualsandfamilies

● Designing living spaces that meet the requirements of individuals and their communities contributestosustainableandinclusivedevelopment.

● Provision of adequate living spaces is essential for disaster-affected populations during the recoveryandreconstructionphases.

● Consideration of cultural and social factors in living space design helps foster a sense of belonging,identity,andculturalcontinuitywithincommunities

● Access to safe and adequate living spaces is a key element in promoting social justice and equalityforallindividuals,regardlessoftheirsocio-economicbackground

The Sphere Handbook, along with the UNHCR Emergency Handbook and the Humanitarian Shelter Guidelines, establishes a minimum standard for living space in shelters These guidelines, reflected in Table, are applicableduringtheemergencyphaseandfortemporaryortransitionalsheltersolutions They specify the minimum requirements for shelter size and height. However, it is important to note that meeting the minimum requirement does not necessarily ensure adequate living conditions, and these guidelines do not mandate a fixed amount of spaceinallcircumstances.Itiscrucialtocarefullyconsider the implications of adopting minimum calculated spaces, as they significantly influence shelter design,

logistics requirements, and costs. Balancing these factors is essential in providing suitable living spaces fordisaster-affectedpopulations.

Inadditiontotheminimumspacerequirement,livingspacesinsheltersshouldconsiderseveralother factors.Theseinclude:

1. Functionality and division: The design of living spaces should take into accounthowfamiliesor individuals gather within the space and how different areas are divided inside and outside the shelter Itshouldconsiderthechanginguseofspaceduringdifferenttimesoftheday

2. Enclosed spaces for various activities: Shelters should provide enclosed spaces with adequate floor area for activities such as sleeping, playing, cooking/eating, washing,andotherdailytasks Thisensuresthecommunity'sdignity,security,andprivacy

3. Risk of overcrowding: The risk of overcrowding should be carefully assessed and managed to avoid an increase in illnesses or the potential spread of diseases Sufficient space should be providedtomaintainahealthyandhygieniclivingenvironment.

4. Accessibility: It is important to consider accessibility within the living spaces, especially for individuals with disabilities Additional space may be required to accommodate their specific needsandensureequalaccesstoallfacilities.

When designing a temporary shelter, it is important to begin with the minimum standard space requirement and then adjust the size based on the specific needs of the local community For example, families with a larger number of members or extended relatives, typically three or more individuals, shouldbeprovidedwithmorespaceorsquarefootagecomparedtoindividualsorcouples Thisallowsfor sufficient sleeping space, larger dining areas, and additional storage capacity, which are essential for families during a disaster. By considering the specific requirements of different household sizes, the design of temporary shelters can better meet the needs of the affected population and provide a more comfortableandfunctionallivingenvironment.

By considering these aspects, shelter designs can enhance the quality of living spaces, promote communitywell-being,andprovideasafeandinclusiveenvironmentforthoseaffectedbydisasters.

2.6Commonprobleminshelters

Over the past decade, considerable progresshasbeenmadeindevelopingvarioussolutionsandstrategies for temporary shelters to assist vulnerable regions and communities in times of need. However, despite these advancements, there are still persistent challenges that have not been effectively addressed in the contextoftemporaryshelters Theseissuesinclude:

2.6.1 Lack of local and cultural considerations: Oneoftheprimarychallengeswithtemporaryshelters is the lack of local and cultural considerations. This stems from a lack of understanding about the post-disaster circumstances experienced by affected communities. In many cases, shelter solutions are developed in a different region by governments, organizations, or international aid agencies who are not familiar with the local area.Thelocalcommunityisoftennotconsultedtounderstandtheirspecificneeds and expectations This disconnect between professionals and the local community can lead to misunderstandings and inadequate solutions that may be culturally inappropriate and unsuitable for the affectedpopulation.

To address these issues, it is crucial to involve the local community in the design process, considering their cultural norms, preferences, and specific contextual requirements. Emphasizing locally appropriate and culturally sensitive designs can result in more effective and sustainable shelter solutions that better meettheneedsandexpectationsoftheaffectedpopulation.

2.6.2 High costs:Thesecondchallengepertainstothehighcostsassociatedwithtemporaryshelters This issue arises because shelters are often produced inforeigncountriesandthenimportedandtransportedto the disaster site The transportation process significantly increases the overall price of each shelter, including external production costs, transportation expenses, and material costs This problem persists because shelters do not utilize the readily available local resources in the affected region or country. In addition to the financial burden, transportation also leads to delays inshelterdeliveriesanddistributions, leaving the affected community in critical conditions without proper shelter. To addressthischallenge,it is important to explore local resources and construction methods that can reduce costs and expedite the shelterresponseindisaster-affectedareas

2.6.3 Future use of units: The final challenge associated with temporary shelters is their lack of future use and the resulting environmental impact Many temporary shelterunitsremainingoodconditioneven after they are no longer needed, but they are often dismantled without consideration for their potential future use. This results in a significant waste of resources and materials. Moreover,thesiteswherethese units were located are often left polluted and not restored to their original condition before the disaster These cultural, economic,andenvironmentalissuesareparticularlyprevalentintemporarysheltersdueto longer-than-anticipated usage periods and the need for additional infrastructure and resources during challenging times To addressthischallenge,itisessentialtoexploreoptionsforrepurposingorreusing

Shipping containers are widely used for transportation and storagepurposes,buttheycanalsobereused as temporary shelters for people who have been displaced by disasters. Shipping containers have some advantages as temporary shelters, such as their strength, durability, portability,andavailability.Theycan also be modified and adapted to suit different needs and preferences of the users, such as adding insulation, windows, doors, partitions, and utilities. However, shipping containers also have some challengesandlimitationsastemporaryshelters,suchastheirsize,shape,weight,cost,andenvironmental impact They may not be suitable for all contexts and climates, and they may require expertsupportand additional resources to install and maintain.

2.11CONCLUSION

Different types of disasters have varying impacts on populations. While some disasters like floods may cause temporary displacement, allowing families to return homeafterafewweeks,otherslikehurricanes or tsunamis can destroy entire communities, leaving them without a physical place to return to In such cases, temporary shelters play a crucial role in bridging the gap between the aftermath of a disaster and theresumptionofdailyactivitiesfortheaffectedcommunity

Temporary shelters are deployed during the early recovery phase and are designed to last longer than emergency shelters. They serve as a transitional solution, providing the affected community with basic needs and asenseofnormalcyduringthepost-disasterperiod Whiletheyarenotpermanenthousing,itis important to acknowledge that the term "temporary" can extend for a considerable period, depending on thetimerequiredforrecovery.Displacedsurvivorsmayresideinthesesheltersformonthsorevenyears. Considering the extended duration of stay, temporary shelters should prioritize comfort, privacy, and security to ensure the well-being and stability of the affected community.

Disaster:flashfloodinuttarakhand2013(andkashmir-2010,2013)

It’s an earthquake and wind resistant house built with most easily available materials and vernacular architectureofthehillyarea.

In June 2013, a multi-day cloudburst centered on the north india state of uttarakhand causeddevastating floodsandlandslidesbecomingthecountry’sworstnaturaldisastersincethe2004tsunami.

In Uttarakhand and kashmir, the need for the mid-term shelter arose before long. People needed something where they could stay warm and with minimumdiscomfortsincewinterwasnottoofaraway. Later when the permanent houses get built this house could be easily dismantled and all the materials reusedintheextensiontothenewconstruction.

Using this design in Uttarakhand threeorganizationshadbuiltmorethan300semi-permanenthousesfor the affected people. Now more than 15 months after the disasteraspeoplearegettingreadytomoveinto their permanent houses many are refusing to dismantle their midterm houses since they are earthquake andcycloneresistant,andarespacious.

once a permanent shelter is established, the occupants will relocate, dismantling this structure and repurposingitscomponentsforfutureuse,minimizingmaterialwasteandpromotingsustainability. However, it is worth noting that this shelteroffersmorethanjustatemporarysolution Intheeventthata beneficiary wishes to transform it into a permanent structure, the design allows for adaptability. By extending the walls to a height of 7 or 8 feet and incorporating a concrete band and wire reinforcement, the shelter can be upgraded to provideincreasedstructuralstabilityanddurability,offeringthepossibility ofalonger-termorevenpermanenthousingoption.

This approach not only facilitates a smooth transition for individuals and families as they rebuild their lives, but it also promotes resourcefulness and resilience in post-disaster scenarios By providing the flexibility to adapt the shelter according to evolving needs and preferences, it empowers beneficiariesto create a living space that meets their specific requirements and fosters a sense ofstabilityandcontinuity intheirdailylives.

Disaster:Bhujearthquake,Gujrat,January2001

Background

On January 26th, 2001, a devastating earthquake measuring magnitude 69 struck, resulting in a significant loss of life and extensive damage Tragically, around 20,000 people lost their lives, while an additional 167,000 individuals were injured. The earthquake left over one million people homeless, impacting 7,633 villages and completely destroying 450 villages The destruction was widespread, with 344,000housescompletelydestroyedand888,000housesreportingdamages.

In the aftermath of the earthquake, non-governmental organizations (NGOs) and contractors worked collaboratively with affected villages to provide ready-made temporary shelters on the victims' own properties These shelters served multiple purposes: they offered families a safe and secure livingspace, allowing themtimetorecoverfromthetraumatheyexperienced Additionally,theprovisionoftemporary shelters granted planners and victims the opportunity to thoroughly assess and study theirreconstruction options, ensuring that the subsequentpermanentsolutionswouldmeetthelong-termneedsoftheaffected communities.

The temporary shelters were constructed using locallyavailablematerialssuchasbricks,wood,andtiles

This approach facilitated the recycling and repurposing of materials for the improvement of future housing. Owners had the flexibility to reuse the materials from the temporary shelters to enhance their newly constructed houses For instance, the temporary shelter could be transformed into a kitchen, a storageroom,oranadditionalhabitableroom,basedonthespecificneedsofthehouseholds.

While these temporary shelters provided immediate relief and a senseofsecurity,theywerenotintended as permanent solutions due to their limited size and capacity The focus was on providing a transitional living space that would facilitate the recovery process and allow communities to plan for long-term reconstruction The flexibility of the shelter design, allowing for material recycling and adaptation,

empowered the affected individuals to gradually improve their living conditions as they moved towards permanenthousingsolutions.

This approach not only addressed the immediate needs of the earthquake-affected populations but also fostered resilience and community participation in the reconstruction process By utilizing locally available materials and incorporating the input and preferencesofthehomeowners,thetemporaryshelter initiative contributed to the sustainable recovery and reconstruction efforts, allowing communities to rebuildtheirlivesontheirownterms (Shigeru Ban Architect(n.d.), Paper Log House,shigeruban.net)

● Shelters that locally procured materials are cost effective over time and provide good opportunitiesforscale-up,

● Shelters with area around 3.5 sq m per person, they provides better living space and livelihoodopportunities;

● The time of making shelter in india context is higher than malaysia project and the amenitiesarebetterprovidedtofullfillthedailyusage

● In the context of India, the potential for allowing temporary shelters to be used as permanent houses is a significant consideration in post-disaster scenarios. However, it is important to note that currently, the concept of temporary shelters transitioning into permanent houses is not widespread in India. This indicates a gap between the existing practice and the potential for utilizing well-designed temporary shelters as permanent housingsolutions.
