In developing countries, factors affecting fish consumption are different between urban and rural households. This study comparatively analyses the disparity in demand for fresh fish between rural and urban households in Cameroon. Using random sampling, data on the weekly consumption of fresh fish were collected between April and May 2015;30 households lived in rural localities while 30 lived in urban areas of Buea Municipality. Consumer’s income, the price of fresh fish, family size, gender and age of consumers represented parameters of interest. These were analyzed using the independent sample t-test. Results revealed that the availability, the income level and price affected fish consumption of rural dwellers while price, taste, income and affordability determined the consumption patterns of urban dwellers. The study equally revealed that the higher the price of fresh fish, the higher the demand for its closed substitutes and the higher the size of the household, the higher the quantity demanded. Gender, education and marital status did not affect the quantity demanded;family size and age negatively influenced consumers’ decision to buy while consumers’ income and price of fresh fish positively influenced consumers’ weekly and monthly expenditure on fresh fish. The study proposes that more information be provided to consumers regarding the numerous nutritional benefits of fresh fish for both rural and urban dwellers. Also, policy makers and marketers need to improve the availability of fresh fish in rural and semi-urban settings.展开更多

This research focuses on household needs like food, clothing, housing, household equipment and supplies, transportation and communication, education and entertainment, healthcare;and also focuses on food items such as grains, meat, eggs, milk, vegetables, fruits and others in urban China. In poor households, the average disposable income per capita is less than or near per capita expenditure;and the Engels coefficient is often over 40%. The data from 1997-2012 in this research is in the provincial level from the Information Website of Development Research Center of the State Council (or “DRCnet”). The authors used the two stage ELES-AIDS (Almost Ideal Demand System) to estimate the price elasticity and expenditure elasticity of the household’s expenditures. According to the results, it is recommended that the government should follow economic law and improves policy efficiency, especially its food policy to alleviate the poverty of low income residents.展开更多

Stratified sampling and typical case study were adopted and 236 questionnaires were collected from four vil- lages, Daxin, Lixin, Longhe and Yongchang. We analyzed the rural-urban migration rate, household income and local geographical factors, focusing on the ratio of remittance income to total household income. Data descriptions and sta- tistical methods, such as Pearson Chi-square test, Contingency coefficient, Eta, Pearson correlation coefficient, t-test, multiple comparisons (LSD test, Tamhane T2, Dunnett T3 and Dunnet C test) were used. The results are as follows. Rural households’ income is diversified in survey villages so the motivation of rural-urban migration in the study area can be partly explained by NELM. The migration rate of households (the percentage of households with migrants in survey households) in survey villages varies from 50% to 86%, while the proportion of remittance income to house- hold income is in the range of 30% to 80%. In the village of Yongchang, with the least average arable land area per household, the remittance income plays a vital role in household income (80%). And the statistical findings show that the proportion is significantly and negatively correlated with arable land area per household. The conclusion is that di- rect effect of migration, i.e., the contribution of remittance to household income, is negatively correlated with the con- tribution of resources to local income.展开更多

This paper expanded Logarithmic Mean Decomposition Index method through introducing variables of urbanization and residential consumption into the model. It also analyzed the influences of six factors as energy structure, energy intensity, population scale, urbanization, residential consumption, and consumption inhibit on regional household energy consumption. Results showed that in 2003-2012, impact of urbanization on regional household energy consumption of Chinese three areas was significantly higher than population size. The "population gathered in eastern region" phenomenon caused eastern region getting the largest population scale effect. Driving force of residential consumption on regional household energy consumption was much higher than the other five effects. Due to the comparative advantage of residential consumption compared with government consumption, investment, and net export, the decrease of consumption ratio promoted the growth of regional household energy consumption. Energy intensity in Chinese three regions kept reducing in 2003-2012. The progress of energy utilization technology slowed the growth of regional household energy consumption, and energy intensity effect was most significant in the central region.展开更多

Rural-urban migration is becoming a part of routine life in rural areas.And remittance is an important component in rural house- hold income.Rural-urban migration increases the arable land area per labor,which releases the tight human-land relationship in villages.In total,the migration increases the rural household in- come and accelerates the sustainable development of rural areas.展开更多

The proposed device will be tested in the Lamkansa district, in the southwestern part of Casablanca city, Morocco. The approach used is a systemic analysis of communication in order to act on a territory. We have been inspired by several methodological developments concerning multi-actor processes of land use planning. We focused our work on the involvement of the inhabitants in the process of household waste collect. The results show that the urban population can help and contribute to the development of complementary solutions to improve the urban environment and their living environment. Moreover, by integrating citizens in HWC processes, as well as decision communication, we can reduce household waste management costs and make it faster and more efficient, through a geo-collaborative, participatory and incentive logic. The approach described in this article is original, not only considering the technologies used to present and share the collected information, but also regarding the concept of integrating several actors in a collaborative/incentive mode. It arouses great interest by combining geomatics with communication and information sciences. It contributes to improve the participation of the inhabitants in the life of their urban environment in order to establish a reinforced dialogue on the future of their city and public health. Also, it involves the development and testing of new devices and tools for multi-actor collaboration.展开更多

From analysis of current problems and situations, it is believed that household registration system should undertake reform and take a new road by means of informationization. Strengthening informationization management in land, population, education and labor market can better perform urban and rural integration.展开更多
