Shelter as Infrastructure for Human Survival, Health, Dignity, and Climate Resilience: An Integrative Review and the SHELTER Systems Framework
Author: SAMUELSON G
Document type: Interdisciplinary review and conceptual framework
Status: Preprint — not peer reviewed
Shelter is more than a physical roof. It is a connected human-protection system involving structural safety, public health, water and sanitation, energy, land tenure, social networks, mobility, livelihoods, governance, dignity, accessibility, environmental performance, and long-term resilience.
This paper presents an interdisciplinary review of shelter across permanent housing, emergency accommodation, disaster response, displacement, homelessness, climate adaptation, and sustainable development. It introduces the author-developed SHELTER Systems Framework, which evaluates shelter options through seven connected domains:
- S — Security of tenure and protection
- H — Health and habitability
- E — Essential services and energy
- L — Location, livelihoods, and social connection
- T — Thermal, structural, and hazard resilience
- E — Equity, accessibility, participation, and culture
- R — Resource efficiency, repairability, and recovery
The central argument is that shelter performance emerges from interactions among these domains. A structurally sound building may still fail as shelter when it lacks secure tenure, sanitation, energy, accessibility, social connection, or protection from environmental hazards.
This study aims to:
- Define shelter as a multidimensional human-protection system.
- Integrate evidence from housing, public health, humanitarian response, engineering, climate science, urban planning, and social policy.
- Examine the shelter continuum from immediate emergency protection to long-term adaptation.
- Identify limitations in approaches that evaluate shelter only as a physical structure.
- Introduce the SHELTER Systems Framework for contextual assessment.
- Support future research, policy development, shelter design, and disaster-recovery planning.
The principal contribution of this paper is the SHELTER Systems Framework, an original seven-domain model for assessing whether a shelter solution is safe, healthy, dignified, accessible, service-connected, locally appropriate, and resilient.
The framework is intended for:
- Research and comparative analysis
- Humanitarian shelter assessment
- Housing-policy evaluation
- Disaster recovery planning
- Climate adaptation
- Community consultation
- Preliminary project appraisal
- Identification of critical shelter-system failures
It is a conceptual tool and should not be treated as a universal certification standard without empirical validation.
This figure presents shelter as a set of interacting layers:
- People, household, dignity, identity, and daily life
- Dwelling envelope and indoor environment
- Water, sanitation, energy, waste, communication, and care services
- Settlement, neighbourhood, mobility, livelihoods, and social networks
- Governance, finance, land systems, law, and public accountability
This figure describes the progression from immediate life safety to long-term resilience:
- 0–72 hours: life safety and exposure control
- Days–weeks: minimum adequacy and stabilization
- Weeks–months: service integration and transitional support
- Months–years: durable recovery
- Long term: adaptation and stewardship
This figure summarizes the seven assessment domains of the proposed framework.
Shelter conditions influence respiratory illness, injury risk, thermal stress, infectious disease transmission, mental health, sleep quality, privacy, safety, and access to care. Health outcomes depend on both building quality and access to essential services.
Emergency shelter must first reduce immediate exposure and mortality risk. However, temporary solutions should not become long-term environments that reproduce insecurity, overcrowding, poor sanitation, isolation, or dependency.
Adequate shelter supports personal safety, identity, family life, privacy, education, employment, and social participation. Housing insecurity can undermine health and economic stability even when a physical structure is available.
Shelter must respond to heat, cold, floods, cyclones, earthquakes, wildfire, sea-level rise, and other hazards. Resilience requires suitable siting, structural design, passive thermal performance, maintenance, early-warning systems, and recovery capacity.
A dwelling cannot function adequately without reliable water, sanitation, drainage, energy, waste management, transport, communication, and access to healthcare, education, and livelihoods.
Shelter systems should consider children, older adults, persons with disabilities, displaced households, low-income communities, women, and groups exposed to discrimination or violence. Participation and culturally appropriate design are central to equitable shelter.
Long-term shelter planning should reduce operational energy use, material waste, avoidable demolition, and lifecycle emissions. Repairability, adaptability, local materials, reuse, and responsible recovery are essential sustainability principles.
The study uses an interdisciplinary integrative-review approach. Evidence and established guidance are synthesized from:
- Public health
- Housing and homelessness research
- Humanitarian standards
- Architecture and building science
- Structural and environmental engineering
- Disaster-risk reduction
- Climate adaptation
- Urban planning
- Human rights and governance
- Sustainable construction
The paper does not report a clinical trial, field experiment, or original human-subject dataset. Its main output is a structured conceptual synthesis and an evaluation framework for future testing.

The framework may be adapted for:
- Comparing proposed shelter designs
- Assessing post-disaster recovery options
- Reviewing temporary accommodation sites
- Evaluating settlement upgrading projects
- Identifying service and infrastructure gaps
- Supporting community-based housing decisions
- Structuring policy discussions
- Designing future empirical studies
Any application should be adjusted to local hazards, climate, law, culture, household priorities, available services, and resource constraints.
This work has several limitations:
- It is an integrative conceptual review rather than a systematic meta-analysis.
- The SHELTER framework has not yet been validated through large comparative datasets.
- Domain weights may differ by geography, population, hazard, and phase of recovery.
- Some shelter indicators may be difficult to compare across legal and cultural settings.
- A composite score should never override critical failures involving life safety, rights, protection, or habitability.
- Repository publication does not constitute peer review.
Shelter should be understood as a living system rather than a standalone object. Its success depends on the interaction of people, dwellings, infrastructure, services, neighbourhoods, institutions, environmental conditions, and rights.
The review shows that a roof or enclosure alone is insufficient. A shelter may be structurally intact while remaining unsafe, unhealthy, inaccessible, unaffordable, insecure, isolated, or environmentally unsustainable. Effective shelter therefore requires simultaneous attention to tenure and protection, health and habitability, essential services, location and livelihoods, physical resilience, equity, and resource stewardship.
The proposed SHELTER Systems Framework provides a practical structure for organizing these dimensions. Its value lies not in producing a universal numerical score, but in making hidden failures visible and encouraging decisions that protect life, dignity, agency, and long-term resilience.
Future research should validate the framework across diverse climates, hazards, cultures, settlement types, and recovery phases. Participatory testing with affected communities will be especially important. The long-term goal is to support shelter systems that are not only physically protective, but also healthy, inclusive, adaptable, service-connected, locally grounded, and capable of recovery.
