Improving compliance with environmental regulations is critical for promoting clean environments and healthy populations. In South Asia, brick manufacturing is a major source of pollution but is dominated by small-scale, informal producers who are difficult to monitor and regulate—a common challenge in low-income settings. We demonstrate a low-cost, scalable approach for locating brick kilns in high-resolution satellite imagery from Bangladesh. Our approach identifies kilns with 94.2% accuracy and 88.7% precision and extracts the precise GPS coordinates of every brick kiln across Bangladesh. Using these estimates, we show that at least 12% of the population of Bangladesh (>18 million people) live within 1 km of a kiln and that 77% and 9% of kilns are (illegally) within 1 km of schools and health facilities, respectively. Finally, we show how kilns contribute up to 20.4 μg/m3 of PM2.5 (particulate matter of a diameter less than 2.5 μm) in Dhaka when the wind blows from an unfavorable direction. We document inaccuracies and potential bias with respect to local regulations in the government data. Our approach demonstrates how machine learning and Earth observation can be combined to better understand the extent and implications of regulatory compliance in informal industry.

The article presents the reasons for which the issue of providing housing to low-income citizens has been a real challenge in Addis Ababa during the recent years and will continue to be, given that its population is growing extremely fast. It examines the tensions between the universal aspirations and the local realities in the case of some of Ethiopia’s most ambitious mass pro-poor housing schemes, such as the “Addis Ababa Grand Housing Program” (AAGHP), which was launched in 2004 and was integrated in the “Integrated Housing Development Program” (IHDP) in 2006. The article argues that the quotidian practices of communities and their socio-economic and cultural characteristics are related to the spatial attributes of co-housing practices. Drawing upon the idea that there is a mutual correspondence between social and spatial structures, it places particular emphasis on the analysis of the IHDP and aims to show that to shape strategies that take into account the social and cultural aspects of daily life of the poor citizens of Addis Ababa, it is pivotal to invite them to take part in the decision-making processes regarding their resettlement. Departing from the fact that a large percentage of the housing supply in Addis Ababa consists of informal unplanned housing, the article also compares the commoning practices in kebele houses and condominium units. The former refers to the legal informal housing units owned by the government and rented to their dwellers, whereas the latter concerns the housing blocks built in the framework of the IHDP for the resettlement of the kebele dwellers. The article analyzes these processes of resettlement, shedding light of the fact that kebele houses were located at the inner city, whereas the condominiums are located in the suburbs. Despite the fact that the living conditions in the condominium units are of a much higher quality than those in the kebele houses, their design underestimated or even neglected the role of the commoning practices. The article highlights the advantages of commoning practices in architecture and urban planning, and how the implementation of participation-oriented solutions can respond to the difficulties of providing housing. It argues that understanding the significance of the endeavors that take into account the opinions of dwellers during the phase of decision-making goes hand in hand with considering commoning practices as a source of architecture and urban planning frameworks for low-cost housing in this specific context. The key argument of the article is that urban planning and architecture solutions in Addis Ababa should be based on the principles of the so-called “negotiated planning” approach, which implies a close analysis of the interconnections between planning, infrastructure, and land.

Reconstruction and urban development in Kabul, Afghanistan, has prompted vast expansion of the clay quarrying and brick making industry. This study identified the extent and distribution of clay quarrying and brick kilns in the greater Kabul area between 1965 and 2018. Very high-resolution satellite imagery was interpreted to quantify and characterize the type, number, and location of brick kilns for 1965, 2004, 2011, and 2018. Geospatial analysis of kilns together with geologic data and the results of hyperspectral image analysis yielded information regarding the extent of relevant mineral resources. Finally, kernel density analysis of kiln locations for each date called attention to their shifting spatial distribution. The study found that the clay quarrying and brick making industry has expanded exponentially. The type of kilns has transitioned from artisanal style clamp kilns to small-scale Bull’s Trench Kilns (BTK), and ultimately to Fixed Chimney Bull’s Trench Kilns (FCBTK). While quarrying has occurred entirely within quaternary windblown loess and clay deposits, artisanal clamp kilns were located in fine sediments containing montmorillonite and FCBTKs have developed in sediments containing calcite and muscovite. The study’s inventory of kilns was then used to estimate kiln workforce at 27,500 workers and production at 1.579 billion bricks per year.

A microfinance scheme was introduced in Malaysia in the year 1987 as one of the alternatives to poverty eradication strategies in the country by the government. Since then, several institutions have created to carry out the agenda of providing small loans to the low-income group to start up their small-scale business to generate more sources of income to support their household consumption. However, for a certain reason, the people still do not find microfinance an important tool to uplift their economic positions. Most of the low-income groups are still unaware of this golden opportunity tailored for them. Besides, the sustainability of these subsidized microfinance systems implemented by Malaysia had not been appropriately studied. This study explores the attractiveness of the products offered by microfinance institutions and emphasizes the option that the participants must start utilizing the product. This research also explores microfinance facilities that contain conventional finance element which is prohibited in Islamic trade. The study also discusses the measures and actions taken by microfinance institutions in serving the low-income group in Malaysia. This paper employs a qualitative method through interviews and content analysis. The report, journal publications, and other related documents were also analyzed in achieving the objectives. The study provides the impact that it may pave the way to an indistinct understanding of how Islamic microfinance institutions sustain their operations.


This study explores women's work prospects in the SME sector of Bangladesh. The researcher has identified two different reasons to conduct this study separately. Number one is that in the last few decades, have played a very active and important role, and the second is that by empowering women, female entrepreneurs build new job opportunities and solve the different problems of society. Small and medium-sized enterprises, which play an important role as engines of economic growth in many countries, provide growth opportunities for low-cost jobs. The results of the study illustrate the correlation between job opportunities for SMEs and women. Women's entrepreneurship is seen as a crucial instrument of women's empowerment and emancipation. Small and medium-sized enterprises, which play an important role in many countries as engines of economic growth, provide opportunities for low-cost employment with growth. The study finding shows the relationship between employment opportunities for SMEs and Women. Women entrepreneurship is seen as a key tool for empowering and liberating women. Developing countries such as Bangladesh are better off starting a small and medium-sized company because Bangladesh belongs to the low-income group facing problems of unemployment, poverty, low savings rate, low capital accumulation. Business on the micro and small scale did not require huge investment, it begins with limited capital. Developing nations such as Bangladesh are better off starting a small and medium-sized business because Bangladesh is part of the low-income community facing unemployment, poverty, low savings rate, low accumulation of capital problems. Micro and small-scale companies did not need tremendous investment but began with minimal resources.

Housing is one of the basic needs of human. Population in Malaysia is increasing and expected to reach up to 35 million in year 2020. This phenomenon creates high demand for housing. To tackle the squatter problems, the government introduces low-cost housing. Low cost house is known as the government house, where the price is cheaper but still comfortable. Although there are many of low-cost housing projects have been completed to cope with the need of the citizen especially for low-income group. However, census report reveled that these is huge demand of low-cost housing. This demand might be because of various factors which are very essential to identify in order to meet the required demand of low cost houses. Hence, this study is carried out to assesse the demand of low cost housing in Melaka, determine the significant factors affecting demand of low-cost housing, and establish PLS-SEM model for assessing factors affecting low-cost housing demand. In this study, data are collected by distributing questionnaire in Melaka state. The collected data from survey was analyzed using statistical software SPSS and presented in graphs and chart. Further, factors affecting low cost housing demand in Melaka were modeled with the SmartPLS v2.0. The model shows the relationship between low cost housing demand and its indicators. The finding of the study showed that most significant indicators affecting the demand of low-cost housing in Melaka are the economic factors which include housing stock, inflation rate and Gross Domestic Products (GDP). The Goodness of Fit showed that the model has substantial explaining power for the assessing factors affecting low cost housing demand in Melaka which the values is 0.481. This means that the economic factor has a great influence on the low-cost housing demand in Melaka.

The year 2014 had witnessed the scenario where most of the states in Malaysia pledged to declare themselves as Zero Squatter state. Thus far, most of the states in Malaysia are still striving to achieve the goal. The government has therefore aspires to reach the target by the year 2020. The Malaysian government under its 5-years National Plan has since introduced the low, medium and high cost housing categories. The housing policy was therefore designed to provide the public of all income levels, particularly the low-income groups, with affordable housing as part of an effort to eradicate squatters. However, despite the various policies, the number of squatter families remains large, especially in the urban areas. This paper therefore, intends to examine the instruments put forward by the government to eliminate squatters and assess the roles of related parties assigned to achieve the government’s mission. Through a qualitative approach, results demonstrated that Malaysia has various types of polices and guidance at both the federal and state levels in relation to low-cost housing provision. These would have supposed to help reduce the number of squatters in the country. However, to date, Malaysia is still experiencing problems with squatters. This calls for further investigation.

Bridgeheader is one of the typology of low-income people in the city who assume that the house is only ‘a springboard’ for their life in the city. This group of people dwelt not far from the location of their place to work; occupying marginal spaces in the city and its environment tend to be slump. Almost all areas in the city of Jakarta have marginal spaces, therefore the government attempt to improve the quality of their houses, for example by providing low-cost housing. In fact the low-cost house which was provided by the government failed to be ‘consumed’ by the brigdeheaders at the time when the used value of the house has been turned into market value. The research aimed to determine such approaches of use value of the house that can be ‘consumed’ by the brigdeheader, but did not undermine the space in the city. Data collection methods using practical observation conducted with interviews. While the analysis using descriptive pragmatic method in four case study area in Jakarta. The findings indicate that the concept of house for this group is not determined only by the ‘low price tag’ but also ‘the way of use’ of the space contributed with the result that the house can be ‘consumed’ well.

Low cost housing in Jakarta – Indonesia is provided by the government for low-income people in urban areas, in line with the program to redevelop or renew slum areas or densely populated neighborhoods for supporting sustainable living environment in urban area. Sustainable living environment will be achived if people who live in low cost housing have the culture which support and apply green principles. The purpose of research is to give knowledge about the change of life-cycle and life stage of low-income people as the first residents as long as they stay in vertical housing, and their culture to green principles. The research objectives are to determine the characteristics of residents as urban people and the factors which influenced, to know how their culture to apply green principles. The research was conducted at four low cost housing in Jakarta. The results showed that currently the families still have characters as informal-traditional, nuclear family and extended family. The residents generally are as employee or entrepreneur in informal sector, and still as low income family. Demographic, socio-culture, and economic are the factors which influenced life-cycle and life stage of low-income people as urban society. People who live in low cost housing still have traditional culture which support to green principles.

'Kathmandu Valley' is vulnerable to air pollution problem due to its topography, which restricts the wind movement and allows pollutants to remain within the valley. Brick kilns, operating in the Valley, are known to be a prime cause of air pollution. There are currently more than 125 brick kilns operating in Kathmandu valley deteriorating its air quality and degrading the health of the people living near the kilns. Recent studies have found that the concentration of particulate matter in the air in an area with brick kilns is three times higher when the kilns are operating than during the off-season. Similarly, the health of students studying at a school situated near a brick kiln was found to be significantly worse than that of students studying in a similar school but located in an area without brick kilns. Other environmental costs of the brick kilns are the reduction in the soil fertility, reduced visibility, drying ground water sources. The use of an old and inefficient technology called Bull's Trench kilns and low quality fuel are the main causes of the problem. Recently the government has decided to ban Bulls Trench brick kilns in Kathmandu in a year and a half. As a result, entrepreneurs are searching for environment friendly and cost effective alternative technologies. There are some technologies currently in practice in India like Vertical Shaft Brick Kiln, Fixed Chimney Kilns which are environment friendly and economically sound. Introduction to these technologies in Nepal can save both ecology and economy. Himalayan Journal of Sciences 1(1): 59-61, 2003

One of the main challenges of developing countries is to shorten the digital divide that exists with developed countries and countries in transition. The government of Ecuador through its National Plan for Technologies and Telecommunications (Plan Nacional de Telecomunicaciones y Tecnologías), has as a goal to give universal access to Technologies of Information and Communication (TICs) to its entire citizens. One of its projects is to assure connectivity and infrastructure in schools. This paper proposes a low-cost open source solution to improve the access to information technology and communication through computers to children of schools in low income areas. The proposed alternative was set out to using the Raspberry Pi 3 s a substitute of standard computer. Its performance and capabilities were put to test comparing them to standard PC main functions. the pilot experiment was implemented at the "Ciudad de Ariel" elementary school, located on Durán, Ecuador.
