A total of 43 people were interviewed using well-structured questionnaires. The collected data were analyzed using descriptive methods. The results showed that local Lagoon breeders are divided into two zones: southwest and southeast. Breeders in the south-western region are generally located in two sub-prefectures of the Tabou Department (Grabo and Oulodio). Tabou’s department alone accounts for 42% of the Lagoon breed in Côte d’Ivoire. Agriculture in this area is traditionally sedentary, practiced for social reasons. On the other hand, the south-eastern zone, located in the departments of Aboisso, Adzopé, Agboville, Grand-Lahou, Jacqueville, Abidjan, Dabou and Sikensi, represents 58% of the Lagoon breeding area in Côte d’Ivoire. This second group is characterised by improved breeding. Most of the farmers interviewed in this zone breed for economic reasons. However, the risk of cross-breeding, which already affects the local Lagoon breed, could be increased by the presence of other species such as the Zebu and Ndamas, or even the Baoulé, in this south-eastern herd. 展开更多

In the contemporary world, there are three interconnected global environmental crises (climate change, biodiversity loss, and pollution). The common thread is the unsustainable pattern of production and consumption, which leads to international and local socio-environmental injustices. Seeking environmental justice in Brazil, the success of the rubber tapper social movement stands out, culminating in the Chico Mendes Extractive Reserve (RESEX) implementation in the Brazilian Amazon. However, the residents have struggled to generate income to help their families’ social reproduction. Conventional payment instruments for environmental services have failed to remunerate the socio-environmental attributes of sustainable products adequately. This paper aims to carry out a socio-environmental economic-ecological valuation of the main extractive products of the RESEX in 2021/2022. To this end, a methodology calculates the cost of social reproduction of rural family production, being a non-market price index reference for monetary valuation. The results indicate the acceptability of the socio-environmental valuation of native rubber and Brazil nuts, as they can guarantee environmental conservation, improve the families’ well-being with adequate income for their social reproduction, as well as value attributes outside the market, which helps in the fight against further expropriation or enclosure of rural families in the Amazon. 展开更多

In West Africa, smallholder farmers in indigenous agricultural societies typically hold considerable knowledge. Therefore, this study was conducted in West Atacora of Benin Republic to assess the drivers of farmers’ perceptions of climate change risk. We used a random sampling technique to select 360 households’ heads who were interviewed regarding different climate change risks perception. Binomial logistic regression was used to assess the drivers of farmers’ perceptions of climate change risks. The results showed that the farmers in drier areas had a higher perception of the global risk of climate change than those in humid areas. The same trend was observed for the seven different individual’s climate change risk investigated. The study identified also membership of farm organizations as main sociodemographic characteristic that explains farmers’ perception of climate change risk perception. These findings are helpful tools to sensitize the local people on climate change risk and cope with the risk in agricultural lands. 展开更多

This results in agricultural damage, ecological damage, economic damage and human health damage. Keshabpur upazilla, Jashore district is considered one of the most arsenic prone areas in Bangladesh. However, there was no research data found regarding presence of arsenic in ground water and its transfer to crops and impacts on human health. A questionnaire-based research was conducted to evaluate the present scenario of this area. However, two representative water samples were collected and analyzed. The data showed that 24% people didn’t know about As, 27% people didn’t know about arsenic effects on human health, 61% people depends on neighbor’s deep tubewell (600 - 750 feet depth) for drinking water, 40% people depend on government-provided deep tubewell for irrigation water, 19% peoples are suffering water scarcity in dry season because groundwater level decreased at that time and people mostly suffered with fever. The other diseases were headache, diarrhea, vomiting, stomach ache, allergy, water pox and asthma. Doctors are providing general treatments but never try to find out the reasons based on As. Therefore, it is still unknown to them about which diseases are caused by As. Water analysis data showed that free CO2, EC, BOD, NH4+, NO3−, Ca2+, Mg2+, As and Fe for drinking water and NH4+, NO3-, As and Fe for irrigation water were found to be higher than the DoE permitted safe water standards. The soil data collected from SRDI also supported the present research data. Continuous irrigation with water builds higher concentration of Ca, Mg, Cu, Fe and Mn in the soil. Unfortunately, no data on As was found from SRDI. This research might work as a baseline research for policy makers and researchers to apply proper management plan in this area. 展开更多

There is currently a dearth of information pertaining to socio-demographic factors and eating practices in a multicultural country like Mauritius. This study was therefore undertaken to probe the different eating practices among an adult sample population in Mauritius in an endeavor to establish significant relationships, if any, with common socio-demographic and socio-economic factors. A self-designed questionnaire, (randomly distributed to n = 387 adults), pertaining to socio-demographic variables, vegetarianism, breakfast patterns, eating out of home meals (OHMs), food frequency questions and dieting practices were asked. Males (21 - 40 yrs) had a significantly (p 0.05) to adherence to the recommendations for the consumption of fish. The socio-demographic factors most influential towards eating practices were gender, age and socio-economic status represented by education and occupation. In conclusion, relationships recorded in the present study were comparable to Western eating practices and the availability of certain foods has compelled Mauritians to develop its own and unique eating patterns which can be of relevance in providing accurate health targets for future nutrition interventions in Mauritius. 展开更多

The main purpose of this study was to examine the association between sociodemographic factors (gender, place of residence, level of education, geopolitical zone, and socioeconomic status) and HCT uptake among young people in Nigeria. The study is a quantitative research guided by one research question and one hypothesis. The target population comprised young people in Nigeria ages 15 to 24 years because the focus of this study was to identify the factors affecting HCT uptake among young people in this age cohort. The representative sample was obtained from the updated master sample frame of rural and urban zones developed by the National Population Commission in Nigeria. This master sample frame was a national survey that comprises all 36 states in Nigeria. Probability sampling technique was used to obtain a sample of 10,091 respondents (ages 15 to 24 years) for the study. The multistage cluster sampling was used to select suitable young people with known probability. Data were collected throughout Nigeria between September and December 2012 from 32,543 households (rural = 22,192;urban = 10,351) using structured and semi-structured questionnaires. The individual questionnaires asked about household characteristics, background characteristics of the respondents. Data were analyzed by inputting them into SPSS v21.0 for analysis and then coded them for each participant. The data were summed using descriptive statistics. Frequencies and percentages;measures of central tendencies were used to answer the research question while nonparametric test such as chi-square was used to analyze non-normally distributed data at 0.5 level of significance. Results of data analysis indicated that the sociodemographic variables of gender, place of residence, level of education, geopolitical zone, and SES were significantly associated with HCT uptake. Among others, it was recommended that examining the efficacy of HCT treatments in Nigeria, along with conducting a demographic analysis of the at-risk population, could be beneficial in informing the authorities who are responsible for allocating finite medical resources. 展开更多

To identify the determinant of the occurrence of IUD expulsion Materials & Methods Based on 25 733 IUD uses from the Chinese Two per Thousand Fertility Survey data, this study examines the patterns and differentials of IUD expulsion rate by characteristics of women, and identifies the socio demographic determinants of IUD expulsion. A Life Table method was used to calculate the cumulative expulsion rate and a random effects discrete time survival model was employed to assess the impact of potential determinants simultaneously on the risk of expelling an IUD. Results Three major findings are observed in this study. First, IUD expulsion was the second main reason, after pregnancy during IUD use, for IUD discontinuation during the first four years of IUD insertion; the expulsion rates were 6.4%, 9.1%, 10.8 %, and 12.0% at 12, 24, 36 and 48 months, respectively. Second, there was a clustering of IUD expulsion: some women experienced repeated IUD expulsions. Third, some socio demographic characteristics and fertility history were associated with the occurrence of IUD expulsion. In particular, the expulsion rate was high among young women, among those with two or more children and among those living in rural areas. Conclusion The above mentioned factors shoald be addressed in order to decrease the IUD expulsion rate and enhance the reprocluctive he alth of women. 展开更多

The Karst of Southwest China is a typical representative of poverty stricken region with impoverishment-degradation spiral. To essentially break away from this vicious circle, the local ecology, economy and society should be rehabilitated, and hence to strengthen the self-development capacity building of the localities. Two considerations are stressed in this article: (1) Poverty alleviation is a system project with great complexities. Any single approach is difficult to success and integrated measures should be taken. (2) Some typical and feasible areas should be selected to demonstrate the project of poverty alleviation and ecological, socio-economic reconstruction. Then, they can be used as a model to promote the sustainable development of the whole region. Based upon these ideals, a project entitled “Reversal of Impoverishment-Degradation Spiral in the Karst of Southwest China' was proposed and has been listed in 《Priority Programme for China's Agenda 21》. 展开更多

She has completed national water resources appraisement and medium to long-term water supply planning. She has been engaging in study on water-deficient regions in North China and Northwest China for about half a century. For solving water shortage problem in northern China, she has put forward the famous South-to-North Water Transferring Projects, which has been set as one of the four biggest national projects in the Tenth Five-Year-Plan period although there are still debates. For promoting water use efficiency, China has been reforming her water management system, including water right system and water price system. There has already been a case of water right purchase. China has also done a lot of research on the interaction between human activity, water and ecosystem. For meeting the need of sustainability and coordinating water resources development and environmental protection, the study of ecological water requirement became very hot in recent years. There are three focuses of socio-economic water cycle study now in China: water transfer projects from the south to the north, water resources management and ecological water requirement. 展开更多

For the scientific management of farmland, it is significant to understand the spatio-temporal variability of soil organic matter and to study the influences of related factors. Using geostatistical theory, GIS spatial analysis, trend analysis and a Geographically Weighted Regression (GWR) model, this study analyzed the response of soil organic matter to climate and socio-economic factors in central Heilongjiang Province during the past 25 years. Second soil survey data of China for 1979-1985, 2005 field sampling data, climate observations and socio-economic data for 1980-2005 were analyzed. First, soil organic matter in 2005 was spatially interpolated using the Co-Kriging method along with auxiliary data sets of soil type and pH. The spatio-temporal variability was then studied by comparison with the 1980s second soil census data. Next, the temporal trends in climate and socio-economic factors over the past 25 years were investigated. Finally, we examined the variation of the response of soil organic matter to climate and socio-economic factors using the GWR model spatially and temporally. The model showed that 53.82% area of the organic matter content remained constant and 29.39% has decreased during the past 25 years. The impact of precipitation on organic matter content is mainly negative, with increasing absolute values of the regression coefficient. The absolute value of regression coefficient of annual average temperature has decreased, and more areas are now under its negative effects. In addition, the areas of positive regression coefficient of annual sunshine hours have northward shifted, with the increasing absolute value of positive coefficient and decreasing absolute value of negative coefficient. The areas of positive regression coefficient of mechanized farming as a socio-economic factor have westward shifted, with the increasing absolute value of negative coefficient and decreasing absolute value of positive coefficient. The area of regions with the positive regression coefficient of irrigation has expanded. The regions with positive regression coefficient of fertilizer use have shrinked. The positive regression coefficient of mulch film consumption has significantly increased. The regression coefficient of pesticide consumption was mainly positive in the west of the study area, while it was negative to the east. Generally, GWR model is capable to investigate the influence of both climatic and socio-economic factors, avoided the insufficiency of other research based on the single perspective of climatic or socio-economic factors. Therefore, we can conclude that GWR model could provide methodological support for global change research and serve as basic reference for cultivated land quality improvement and agricultural decision making. 展开更多

In recent years, the role of human activities in changing sediment yield has become more apparent for the construction of hydraulic engineering and water conservation projections in the Upper Yangtze River, but it has not been evaluated at the macro scale. Taking Sichuan Province and Chongqing City as an example, this paper studies the relationship between socio-economic factors and sediment yield in the Upper Yangtze River based on section data in 1989 and 2007. The results show that sediment yield is significantly correlated with population density and cultivated area, in which the former appears to be more closely related to sediment yield. Moreover, in the relation of sediment yield vs. population density, a critical value of population density exists, below which the sediment yield increases with the increase of population density and over which the sediment yield increases with the decrease of population density. The phenomenon essentially reflects the influence of natural factors, such as topography, precipitation and soil property, and some human activities on sediment yield. The region with a higher population density than critical value is located in the east of the study area and is characterized by plains, hills and low mountains, whereas the opposite is located in the west and characterized by middle and high mountains. In the eastern region, more people live on the lands with a low slope where regional soil erosion is slight; therefore, sediment yield is negatively related with population density. In contrast, in the western region, the population tends to aggregate in the areas with abundant soil and water resources which usually lead to a higher intensity of natural erosion, and in turn, high-intensity agricultural practices in these areas may further strengthen local soil erosion. It is also found that population tends to move from the areas with bad environment and high sediment yield to the areas with more comfortable environment and less sediment yield. The natural factors have greater influence on sediment yield of western region than that of eastern region. Generally, the natural factors play a dominant role on sediment yield in the Upper Yangtze River. 展开更多

Objective To determine the associations of socio-economic and psychosocial factors with active and passive smoking in older adults. Methods Using a standard interview method, we examined random samples of 6071 people aged 〉 60 years in 5 provinces of China during 2007-2009. Results World age-standardised prevalence for current and former smoking in men was 45.6% and 20.5%, and in women 11.1% and 4.5%. Current smoking reduced with older age but increased with men, low socioeconomic status (SES), alcohol drinking, being never-married, pessimistic and depressive syndromes. Former smoking was associated with men, secondary school education, a middle-high income, being a businessman, being widowed, less frequencies of visiting children/relatives and friends, and worrying about children. Among 3774 never-smokers, the prevalence of passive smoking was 31.5%, and the risk increased with women, low SES, alcohol drinking, being married, having a religious believe, and daily visiting children/relatives. There were sex differences in the associations, and an interaction effect of education and income on smoking and passive smoking. Conclusion Older Chinese had a higher level of smoking and passive smoking than those in high income countries, reflecting China's failures in controlling smoking. The associations with low SES and different psychosocial aspects and sex differences suggest preventative strategies for active and passive smoking. 展开更多

The interaction between urban space and individual behavior has led to essential social, economic and environmental consequences. Behavioral geography provides a new effective theoretical and methodological framework to investigate behavior patterns in cities. In recent years, behavior approach has become an influential analytical paradigm in Chinese urban geography. This paper provides an overview of behavioral geography research in China, by introducing the theoretical and empirical progress in behavior analysis. It is argued that behavioral approach offers a new perspective to understanding China's urban sociospatial reconstruction and addressing social and environmental issues at micro scale. Although theoretical development still lags behind developed countries, Chinese scholars have made much progress in empirical investigations of classical socio-spatial behavior theories. This paper also provides an overview of new trends in Chinese behavioral geography that has started to apply the behavioral approach to urban social, economic and environmental issues. This paper suggests that social dimensions of behavior should be addressed more comprehensively and rigorously by using interdisciplinary theoretical and methodological frameworks, to better understand the complexity of Chinese cities and research the critical social and environmental issues in cities. 展开更多

Floods are the most devastating hazards that have significant adverse impacts on people and their livelihoods. Their impacts can be reduced by investing on: 1) improving the forecasting skills of extreme and heavy rainfall events, 2) development of Impacts Based Flood Early Warning System (IBFEWS) and 3) effective communication of impacts from anticipated extreme or heavy rainfall event. The development of IBFEWS however, requires a complete understanding of factors that relates to the formation of extreme or heavy rainfall events and their associated socio-economic impacts. This information is crucial in the development of Impacts Based Flood Forecasting Models (IBFFMs). In this study, we assess the socio-economic impacts of the December 2011 flood event in Dar es Salaam as the preliminary stage in the development of IBFFMs for the City of Dar es Salaam. Data from household survey collected using systematic random sampling techniques and structured questionnaires are used. The survey was conducted to acquire respondent’s views on the causes of floods impacts, adaptive capacity to extreme or heavy rainfall events and adaptation options to minimize flood impact. It is found that the main causes of floods were river overflow due to heavy rainfall and blocked drainage system. Poor infrastructure such as drainage and sewage systems, and ocean surge were identified to be the causes of observed impacts of the December 2011 flood event in Dar es Salaam. Death cases analysis showed that 43 people were reported dead. The flood event damaged properties worth of 7.5 million Tanzania shillings. Furthermore, the Tanzania Government spent a total amount of 1.83 billion Tanzanian shillings to rescue and relocate vulnerable communities that lived-in low-lying areas of Jagwani to high ground areas of Mabwepande in Kinondoni district. 展开更多

AIM: To evaluate the association between various lifestyle factors and achalasia risk.METHODS: A population-based case-control study was conducted in Northern Ireland, including n = 151 achalasia cases and n = 117 age- and sexmatched controls. Lifestyle factors were assessed via a face-to-face structured interview. The association between achalasia and lifestyle factors was assessed by unconditional logistic regression, to produce odds ratios(OR) and 95% confidence interval(CI).RESULTS: Individuals who had low-class occupations were at the highest risk of achalasia(OR = 1.88, 95%CI: 1.02-3.45), inferring that high-class occupation holders have a reduced risk of achalasia. A history of foreign travel, a lifestyle factor linked to upper socioeconomic class, was also associated with a reduced risk of achalasia(OR = 0.59, 95%CI: 0.35-0.99). Smoking and alcohol consumption carried significantly reduced risks of achalasia, even after adjustment for socio-economic status. The presence of pets in the house was associated with a two-fold increased risk of achalasia(OR = 2.00, 95%CI: 1.17-3.42). Nochildhood household factors were associated with achalasia risk.CONCLUSION: Achalasia is a disease of inequality, and individuals from low socio-economic backgrounds are at highest risk. This does not appear to be due to corresponding alcohol and smoking behaviours. An observed positive association between pet ownership and achalasia risk suggests an interaction between endotoxin and viral infection exposure in achalasia aetiology. 展开更多

Hydrological models are often linked with other models in cognate sciences to understand the interactions among climate, earth, water, ecosystem, and human society. This paper presents the development and implementation of a decision support system(DSS) that links the outputs of hydrological models with real-time decision making on social-economic assessments and land use management. Discharge and glacier geometry changes were simulated with hydrological model, water availability in semiarid environments. Irrigation and ecological water were simulated by a new commercial software MIKE HYDRO. Groundwater was simulated by MODFLOW. All the outputs of theses hydrological models were taken as inputs into the DSS in three types of links: regression equations, stationary data inputs, or dynamic data inputs as the models running parallel in the simulation periods. The DSS integrates the hydrological data, geographic data, social and economic statistical data, and establishes the relationships with equations, conditional statements and fuzzy logics. The programming is realized in C++. The DSS has four remarkable features:(1) editable land use maps to assist decision-making;(2) conjunctive use of surface and groundwater resources;(3) interactions among water, earth, ecosystem, and humans; and(4) links with hydrological models. The overall goal of the DSS is to combine the outputs of scientific models, knowledge of experts, and perspectives of stakeholders, into a computer-based system, which allows sustainability impact assessment within regional planning; and to understand ecosystem services and integrate them into land and water management. 展开更多
