Healthy housing is a function of provision of adequate physical, social and mental conditions for healthy environment. It is a function of both intrinsic and extrinsic attributes of housing that can influence human health. Environment and human activities are omen to development. The effects are manifested in generating land use problems such as congestion, sprawl development, incompatible land uses, building alterations and change of uses, the menace of temporary structures, alteration of land use functions, conversion of open and future spaces, and land degradation. Alagbede village is one of the areas that require such development drive. The study is required to facilitate this need. This research effort is to examine the environmental effect of squatter settlements in Alagbede village, Ikeja, Lagos State Nigeria. The paper examined housing conditions in terms of privacy, adequate space, physical accessibility, adequate security, security of tenure, structural stability and durability, adequate lighting, and ventilation, and basic infrastructure (such as water supply, sanitation, and waste management facilities including suitable environmental quality and health related factors and its influence on the residents of Alagbede area, Ikeja Lagos State. Approach includes the development of database and choice of appropriate data source (primary and secondary data sources). From the methodology, there were questionnaire administration, direct interview of respondents, collection and updating of the base maps, and the use of necessary field instrument for the study. The data gathered were analysed using descriptive method. The end result has revealed a number of environmental problems due to the existence of these settlements (Alagbede village). These problems are poor drainage system, noise pollution, illegal refuse dump sites, slum situations etc. Appropriate recommendations in form of short time and long term solutions were suggested to conclude the research work.

Bangladesh is a land scarce country where per capita cultivated land is only 12.5 decimals. It is claimed that every year about one percent of farm land in the country is being converted to non-agricultural uses. The study is based mainly on field survey covering 2 villages (Narikel Baria and Baze Silinda) from 10 sub-urban villages around Rajshahi City Corporation under Paba Upazila of Rajshahi district. The study area was selected purposively and the respondents of this research work were selected randomly. The major focus was on to mention the general land use pattern of the area, estimates the agricultural land conversion besides determining the causes and consequences affecting such conversion. Both Narikel Baria and Baze Silinda villages were selected as study area because of its relatively higher growth in infrastructure. In order to fulfill the goal of this study, primary and secondary data were collected from various sources and to analyze and process of collected data the SPSS, Excel and Arc GIS software were used. Different types of descriptive statistics were applied for representing the analyzed data. It is observed that the land conversion form agriculture to non-agriculture allied in recent time is more than the previous time due to gradually increasing land demand in housing and relevant services which invites adverse impact on agricultural land as well as its dependent population. So, it is necessary to take integrated land-use planning to offer better options for the fulfillment of land demand both of housing and agricultural sectors.

Gosaba C.D. Block is an active tidal island of the Indian Sundarban. In this island, human-induced modification of the natural drainage system poses serious threats to the estuarine environment. It was started during the British colonial period through the construction of embankment to protect the reclaimed coastal land from saline water ingression. The rapid growth of population over the last few decades has triggered the changes in the drainage network and also altered the land use land cover of the study area. The human encroachment on the drainage area has hampered the sedimentation process as well as water circulation in the delta. As a result, the island is gradually transforming into saucer-shaped form, which aggravates various coastal threats like flood inundation, waterlogging and embankment breaching during extreme environmental events. To study the spatio-temporal change of the drainage network pattern from 1955 to 2018, different multi-temporal satellite images, US Army Toposheet, Census of India Report (2001 and 2011) and Human Development Report (2014) have been used as a source of secondary data for the analysis in ArcGIS environment. In addition to this, instrumental surveying has been done to measure the slope direction in relation to land use land cover and a questionnaire survey was conducted to understand the livelihood status of people influenced by various coastal threats and risks due to the drainage congestion. The study reveals that population density has gradually increased in recent decades and is negatively correlated with the drainage density on the island. The choking of the surface drainage canals has increased the problem of waterlogging in agricultural fields, which affected their productivity. Therefore, a strategy for management of the drainage network needs to be urgently implemented in order to protect the life and livelihood of rural people from various coastal threats.

Saint Martin’s island is one of the unique coral islands and popular tourist destinations in Bangladesh due to its location and favourable environmental condition. The present study has been taken to know the present and past land use pattern, and to explore the existing drainage system and wastes management of Saint Martin’s island in Bangladesh. To achieve the goals of the study, both primary and secondary data have been collected and incorporated. Primary data have been collected through field observation, questionnaire survey, and focus group discussion (FGD). Total 200 questionnaires have been conducted by random sampling during summer and winter season in the year of 2015. Secondary data were also collected from various official records and related researchers’ publications and articles. It is observed from the study that land use pattern of Saint Martin’s island has already been changed and still changing randomly due to increase of inhabitants, settlers and tourists. Most of the agricultural land and vacant lands are going to turn into the hotels, resorts and other human settlements. There is no structural drainage system in this Island. Moreover, most of the wastes are going to be produced by the tourists, fishermen, hotels and restaurants. The present study suggested taking necessary initiate through solving the waste mismanagement problem and proper drainage system for this unique coral island.

The simulation of future land use can provide decision support for urban planners and decision makers, which is important for sustainable urban development. Using a cellular automata-random forest model, we considered two scenarios to predict intra-land use changes in Kumamoto City from 2018 to 2030: an unconstrained development scenario, and a planning-constrained development scenario that considers disaster-related factors. The random forest was used to calculate the transition probabilities and the importance of driving factors, and cellular automata were used for future land use prediction. The results show that disaster-related factors greatly influence land vacancy, while urban planning factors are more important for medium high-rise residential, commercial, and public facilities. Under the unconstrained development scenario, urban land use tends towards spatially disordered growth in the total amount of steady growth, with the largest increase in low-rise residential areas. Under the planning-constrained development scenario that considers disaster-related factors, the urban land area will continue to grow, albeit slowly and with a compact growth trend. This study provides planners with information on the relevant trends in different scenarios of land use change in Kumamoto City. Furthermore, it provides a reference for Kumamoto City’s future post-disaster recovery and reconstruction planning.

Incessant flooding is a major hazard in Lagos State, Nigeria, occurring concurrently with increased urbanization and urban expansion rate. Consequently, there is a need for an assessment of Land Use and Land Cover (LULC) changes over time in the context of flood hazard mapping to evaluate the possible causes of flood increment in the State. Four major land cover types (water, wetland, vegetation, and developed) were mapped and analyzed over 35 years in the study area. We introduced a map-matrix-based, post-classification LULC change detection method to estimate multi-year land cover changes between 1986 and 2000, 2000 and 2016, 2016 and 2020, and 1986 and 2020. Seven criteria were identified as potential causative factors responsible for the increasing flood hazards in the study area. Their weights were estimated using a combined (hybrid) Analytical Hierarchy Process (AHP) and Shannon Entropy weighting method. The resulting flood hazard categories were very high, high, moderate, low, and very low hazard levels. Analysis of the LULC change in the context of flood hazard suggests that most changes in LULC result in the conversion of wetland areas into developed areas and unplanned development in very high to moderate flood hazard zones. There was a 69% decrease in wetland and 94% increase in the developed area during the 35 years. While wetland was a primary land cover type in 1986, it became the least land cover type in 2020. These LULC changes could be responsible for the rise in flooding in the State.

Abstract The purpose of this study is to identify the trend of the employment status in 65 years or older adults who reside in South Korea and to explore the relationship between the status of employment and individual and family-related factors. This study utilized 10-year and 6-wave secondary data from the Korean Longitudinal Study of Ageing (KLoSA). The original panel sample is a random sample of 10,254 adults who are 45 or older, but for the aim of this study, the participants younger than 65 years were excluded. The number of samples in each wave is different, ranging from 4,013 to 4,335 due to the death of the participant, the rejection of additional interviews, and the refreshment participant collected in Wave 5. The findings indicate that the absolute employment of the people aged 65 or older and the proportion of working people among those have increased over the past decade. In this study, it is also found that there is a close relationship between employment status and individual factors such as gender, educational background, health condition, region, etc. Moreover, the results suggest that there are various facets of the relationship between employment status and family-related factors including whether living with children, the number of the member whom I help with daily activities, the total amount of financial support from/to children/parents/other family or whether participating social activities, etc. The implications of the need for employing the older population and the consideration family-related factors in the policy-making process in Korea are discussed.

Abstract In FY 2018-2019, the National Institutes of Health devoted $2,387,505,711 to projects studying depression. Before and following their arrival into the United States stressful life circumstances may render African immigrants particularly at risk for depression. The objective of this study is to provide an estimate and identify correlates of depressive symptoms in older (≥50 years) African immigrants. We performed secondary data analyses of the Older African Immigrant Health study (n = 148). Bivariate analyses evaluated associations between depressive symptoms and sociodemographic and immigration-related factors. Depressive symptoms were measured with the PHQ-8 scale and scores of ≥ 5 were considered indicative of depressive symptoms. The mean age of participants was 62 years (SD:8.2), 61% were female, 30% had less than high school education, and 58% reported having health insurance coverage. Thirty percent of the sample had depressive symptoms (PHQ-8 score of ≥ 5) but only one individual would be classified as having moderately severe or severe depression (PHQ-8 ≥15). Depressive symptoms did not differ by age, marital status, education, or income. There was a statistically significant difference in depressive symptoms by reason for migration, recruitment location, and employment status. Although only one participant would be classified as severely depressive, a large proportion of this sample had depressive symptoms. Mental health concerns were reported as a significant health problem for African immigrants visiting a community service organization in New York. More research is needed to examine the prevalence, immigration-related correlates, predictors, and health ramifications of depression in older African immigrants.

Drainage of peatlands will lower the water table, decompose the organics matter and increases the fire risk. Therefore knowledge of C emission rate is very important for drainage system planning, in order to preservepeat. Scientific methods that used in this study: calculation of thickness/ depth of the peat, peat volume, oxidized peat volume, C dry peat weight and CO2 equivalent. The rate of emission C is calculated on the basisof emission C and subsidence time. Furthermore, the emission rate C (Mton CO2/ yr) is calculated based on 4 (four) model/ scenario concepts, i.e: actual/ existing condition, plantation, canal blocking and canal blocking with reforestation. This activity was conducted in Sei Ahas, Kapuas, Central Kalimantan and Sungai Buluh, Tanjung Jabung Timur, Jambi. Based on research, it was found that land use change will greatly affect the change of ground water level of peat that contributes to increases the emission of C to the atmosphere.
