What Qualities Do Building Materials Used In Informal Settlements Have?

Informal settlements, also known as favelas, slums, bidonville, squatters, and shanty towns, are unplanned urban areas with high population density. They often lack access to basic services such as clean water, sanitation, electricity, and waste collection. Iron sheet, locally referred to as mabati, is the most diffuse building material in these areas, used for cladding and roofing. These areas are densely populated due to high demand for affordable housing.

Building with natural materials has proven to be a sustainable approach in addressing the needs of affordable and healthy housing and improving living conditions in informal settlements. These settlements provide shelter to millions of poor urban dwellers in developing countries. This paper reviews physical and socio-economic aspects of informal settlements, aiming to identify floor slabs that allow inhabitants to self-construct taller buildings safely and at low cost.

Information about informal settlements is lacking, with houses built with temporary materials and without formal planning. The study builds upon the informal development stages (IDS) and explores the characteristics and relationships of these settlements. It also examines growth and transformation variables, as well as the qualities of building materials used in these settlements.

Informal settlements present deficiencies not only in terms of construction materials but also in terms of public services, such as roads or pedestrian spaces. Building characteristics, such as size, shape, pattern, and inter-building distances, are analyzed at the object level.

Informal settlements are characterized by informal land tenure, inadequate access to basic urban services, substandard housing, and a cycle of reuse. Sustainable construction methods can help reduce exposure and vulnerability in the housing sector, particularly in developed countries where conventional building methods will consume nearly 80 percent of the CO2 budget until 2050.

What are the characteristics of settlements?

Settlements are classified into four categories: urban, rural, compact, and dispersed. These categories are based on the settlement pattern and the presence of a key resource. The term “settlement” refers to a group of people who have settled together in a region. The settlements can range in size from small, isolated communities to large, developed urban centers.

What are 3 characteristics of the informal sector?

The informal economy lacks written rules, agreements, and fixed wages, relying on daily earnings. On the other hand, the formal economy has an organized system of employment with clear rules, a standardized relationship between employers and employees, and fixed hours and salaries. Employees are expected to work under a decent work environment, receive benefits like leave, savings, and loans, and have an organized association or union for their grievances.

They are also covered by social protection benefits like life insurance, health insurance, pension, and gratuity. People working in civil service, public sector units, government service, defense, multinational companies, schools, colleges, research institutes, management organizations, and banks belong to the formal sector.

What are the main problems of informal sector?

The informal sector, which is hidden from monetary, regulatory, and institutional authorities, accounts for about a third of GDP and 70% of employment in emerging market and developing economies. This sector is associated with low productivity, reduced tax revenues, poor governance, excessive regulations, and poverty and income inequality. Addressing the challenge of pervasive informality requires comprehensive policies that consider country-specific conditions.

Initiatives to boost long-term development include reducing regulatory and tax burdens, expanding access to finance, improving education and public services, and strengthening public revenue frameworks. Since 1990, both informal output and employment have declined, particularly in countries with higher output growth, rapid physical capital accumulation, and improved governance and business climates.

What is the process of informal settlement?

Collaborative divorce is a method where both parties propose their ideal settlement instead of going to court. This informal process allows for a quicker compromise and direct negotiation. It is cost-effective as the lawyer’s involvement is limited. In the initial settlement offer, it is important to ask for what you want and believe you deserve, while considering what your former partner will likely want and what they believe they deserve. Negotiating in good faith and respect for your ex-spouse will result in a more productive process. This process can be more cost-effective than hiring legal representation.

What are the characteristics of the informal settlement?

The infrastructure of informal settlements is frequently inadequate, the environments unsuitable, the population densities high, the dwellings inadequate, access to health, education, and employment opportunities poor, and the government ineffective.

What are the characteristics of informal?

The informal sector is typified by the presence of small, unregulated workplaces, a prevalence of unsafe working conditions, a lack of requisite skills, low incomes, extended working hours, and restricted access to information, markets, finance, training, and technology.

What are informal settlements characterized by?

The Fifth Housing and Habitat Forum for Latin America and the Caribbean, organized by Habitat for Humanity and convened through the Urban Habitat and Housing Practice Platform, has unanimously called for housing as a fundamental tool to address the climate and social crisis affecting the region. The forum, organized by Habitat for Humanity, brought together a diverse group of stakeholders, including government representatives, sustainable development experts, community leaders, and academics, to analyze and co-construct comprehensive solutions to current housing and urban challenges.

The region has faced increasing challenges related to climate change and social inequality, exacerbated by the global health emergency. The housing deficit has become even more acute, underscoring the urgent need to address these problems from a comprehensive, horizontally and vertically coordinated, and sustainable perspective. The central theme of the forum was housing as a cornerstone in the fight against the climate crisis and social problems aggravated by the pandemic.

What are the hazards of informal settlements?

The informal settlements are exposed to a number of environmental risks, including underground fires, air and water pollution, sinkholes, abandoned mining areas, and acid mining drainage.

What are the factors affecting informal settlements?

Informal settlements are a result of various factors such as population growth, rural-urban migration, lack of affordable housing, weak governance, economic vulnerability, marginalization, and displacement caused by conflict, natural disasters, and climate change. Many governments fail to acknowledge the existence of these settlements, which undermines city-wide sustainable development and prosperity. These settlements are geographically, economically, socially, and politically disengaged from urban systems and excluded from urban opportunities and decision-making.

City government attitudes towards informal settlements range from opposition and eviction to reluctant tolerance and support for legalization and upgrading. Upgrading informal settlements through tenure regularization and infrastructure provision is widely accepted as preferable to relocation, helping to sustain social and economic networks essential for livelihoods.

Living in informal settlements disproportionately affects certain groups, such as women, who often face barriers in accessing livelihood opportunities and home-based workers. Male-biased land tenure policies and restrictions on women’s rights to own property decrease the likelihood of alternative housing options, and poor quality housing, eviction, and homelessness can increase the risk of insecurity and sexual violence.

What is an example of an informal settlement?

Informal housing, often referred to as slums, shanty towns, squats, homelessness, backyard housing, and pavement dwellers, is a prevalent issue globally, particularly in developing countries. This is due to the need for radical physical interventions in cities to accommodate international firms and markets, displacing “modest, low-profit firms and households”. Persistent conflict and insecurity can weaken institutions that record and formalize housing transactions.

Households lacking economic resilience to repurchase in the same area or relocate to a place with similar economic opportunities are prime candidates for informal housing. For instance, in Mumbai, India, fast-paced economic growth, inadequate infrastructure, endemic corruption, and restrictive tenancy laws have left the city unable to house the estimated 54 who now live informally. Informal housing is often built incrementally, as householders acquire the resources, time, and security to build additions and enhancements.

Which is a major factor affecting settlements?

Human settlements are organized, structured habitations in various regions, influenced by a number of factors, including the availability of water, the presence of natural resources, climatic conditions, and the characteristics of the region in question.
