The Impacts of Urbanization to Improve Agriculture Water Use Efficiency—An Empirical Analysis Based on Spatial Perspective of Panel Data of 30 Provinces of China

China has witnessed accelerated urbanization since the reforms and open policies which began in 1978. This eventually resulted in increased residential water requirements and worsening water shortages, particularly in the current century. In the context of resource and environmental constraints, improving agricultural water use efficiency (AWUE) is a crucial issue to ensure food security, improve the ecological environment, and meet the needs of sustainable agricultural development. Based on the panel data of 30 provinces in China from 1999 to 2018, the article uses the Super-SBM model to measure the AWUE. Moreover, the study uses the entropy method to establish the urbanization evaluation index system from the dimensions of population, land, economy, measures the comprehensive level of urbanization development, and further constructs a dynamic spatial econometric model. We use the unconditional maximum likelihood estimation method to evaluate the impact of urbanization development on AWUE and its heterogeneity. The findings reveal that the AWUE considering undesired outcomes has generally shown a steady improvement, but there is ample space for resource conservation and environmental protection, and there are noticeable differences among regions. The decomposition of spatial effects shows that urbanization development in each region has a short-term positive effect on AWUE in the region and neighboring regions, and a long-term effect exists only in the western region. The impact of urbanization in different dimensions has been found that both land urbanization and economic urbanization contribute to the improvement of AWUE, while population urbanization helps to improve AWUE by improving the awareness level of the farmers.

The Meaning and Path of Reconstruction of Cultural Value in Rural Schools

In the process of new-type urbanization development, the gradual discard and ignorance of rural cultural characteristics within rural education eventually led to the loss of cultural value of rural schools. Meanwhile, rural schools play the critical role of carrying out the cultural transmission and innovative development, therefore, the reconstruction of the school value also contributing to the realization of cultural value, including the aspects such as the rejuvenation of social education function, the cultivation of cultural perceivers, and the inheritance of outstanding culture. On the basis of rationality carefully examined the meaning of rural school cultural value, it is suggested to revoke the consciousness of rural school culture, enhancing the sense of belonging of rural teachers, and the construction of rural-school cultural community, so as to promote the reconstruction of rural school cultural value.

DESCRIPTION AND MAPPING OF URBANIZATION DEVELOPMENT IN SUMATERA UTARA

The number of urban residents continues to increase each year due to the mobility of the population from villages to cities (urbanization). Aims this article to describe the development of urbanization in North Sumatra. Method of research is library research, data collection is carried out by taking from various sources such as BPS data, journals, documentation, and coupled with observational data then analyzed descriptively. This research found that the population development of North Sumatra (North Sumatra) is still concentrated in Medan City. Although its geographical area is only 0.36% of North Sumatra's area, Medan is inhabited by 2,279,894 million people. The concentration of the population of North Sumatra in Medan is due to the ongoing urbanization or migration of people from villages to cities. The high number of urban residents can be a problem for the government, one of which is the emergence of the phenomenon of poverty, homelessness, and congestion. Often people who move to urban areas have big reasons and expectations such as wanting to get a job, high wages, prestige, and wanting to enjoy urban facilities. The conclusion is the development of the urban population in North Sumatra is in line with the rapid development of infrastructure, such as toll roads, and industries built by the government or the private sector continue to grow. The increasing level of urbanization shows the increasing number of people living in urban areas (cities) which causes the population to become denser in urban areas. The large number of people who urbanize in North Sumatra is due to economic and social factors.Keywords: Urbanization, Mapping, Development, Nort Sumatra

Recent land cover and use in Romania: A conservation perspective

The study of land cover and use changes is important for sustainability, given that they are part of the global changes affecting our environment. In order to understand the mechanisms determining them, land cover and use changes must be studied based on their associated transitional dynamics. The present research aims to look at the most recent land cover and use changes from Romania, chosen as an example for post-socialists transitions. The methodology was based on applying geo-spatial analyses to data on land cover and use changes and natural protected areas. The results indicate that the most prominent transitional dynamics are deforestations and abandonment of cropland, rooted in the post-socialist property restitution. Furthermore, the study identified transitional dynamics indicating the human pressure within the natural protected areas, including urbanization, development of agriculture, and deforestation. Although subject to limitations bound to the use of CORINE data, the findings are important for understanding the environmental impact of socio-economic drivers, and provide additional evidence for the fact that emerging economies tend to sacrifice the environment during the economic crises.

Identification of Villages’ Development Types Using a Comprehensive Natural–Socioeconomic Framework

The establishment of a comprehensive framework to identify village development types is crucial to formulate plans for rural development and promote rural revitalization. This study proposed a natural–socioeconomic framework to identify the types of villages based on field survey, statistical data, and multi-source remote sensing images. The framework was constructed by combining the two-dimensional natural suitability/restriction evaluation and the four-dimensional socioeconomic development level evaluation. Then, the modified multiplication-weighted summation method and the coupling coordination degree algorithm were employed to identify the villages’ development types. A total of 774 villages of the Laiyang County, eastern China were used as the study areas to examine the framework. The results demonstrated the following. (1) There were 243,318 and 151 villages with high, moderate, low natural suitability, and 62 villages with natural restrictions; and 158,366 and 250 villages with high, moderate, and low economic development level, respectively. The distribution characteristic of natural evaluation was “high in the southwest and low in the northeast”, and the socioeconomic development level was generally centered on the urban area, which presented a “high–medium–low” circle-layer distribution structure. (2) There were 247 villages with high-level coupling coordination, 464 villages with intermediate coupling coordination, 1 village with low-level coupling coordination, and 62 villages with disordered coupling. (3) Based on the coupling coordination evaluation results, villages in the study area were grouped into five types: urbanization development (31%), construction development (16%), agglomeration linkage development (27%), decrease and improvement development (18%), and relocation and integration development (8%). The framework of villages’ development types identification established in this study can enrich the theory of rural geography, and the applied research results can provide a basis for rural revitalization and development planning.

The Importance of Public Participation in Sustainable Solid Waste Management

This study aims to do comparative analysis of what influence the SWM in Indonesia and the Philippines. As Sustainable Development Goals (SDGs) will not be achieved as long as the Solid Waste Management problem is left unsolved. Municipal Solid Waste Management (MSWM) has become a common issue in most developing country along with the rapid urbanization development and globalization. Qualitative approach chosen to analyze literatures selected related to SWM during 2000-2020. Data obtained from previous studies in this article were analyzed by the NVivo 12 Plus. The results shown that governance and participation become the main factors affected the status of MSWM as it is mentioned in most of the previous studies in the Philippines. Which is different with the previous studies in Indonesia.

Importance of Recycling the Waste-Cables Containing Copper and PVC

Urbanization, development of economy, increasing population and improved living standards and lifestyle have caused a sharp growth in waste. Inappropriate or inefficient waste disposal techniques can cause serious air, soil, and groundwater pollution, which subsequently can negatively affect the urban environment and threaten the health of residents. The goal of waste management is to move to a circular economy in which waste does not exist. If there is no possible way to reduce or reuse waste, the best solution is recycling it. Recycling brings abundant benefits on the economic and ecological levels levels, and helps reduce overall human health risk of adverse impacts. Recycling of the waste-cables which contain PVC and copper replaces the production of virgin PVC and mining of copper from copper ore, it reduces landfill solid waste pressures, saves energy and water sources, reduces emissions to environment, and also reduces negative impacts from improperly dispose of waste, etc. This paper presents an overview of recycling techniques for the waste-cables containing copper as a core and polyvinyl chloride as an insulating layer or sheath. It also lists advantages and disadvantages of these techniques and importance of recycling this type of waste.

Does Green Innovation Promote New Urbanization development? From the Perspective of Coupling Coordination between Green Innovation and New Urbanization

Green innovation has become the mainstream of the era, and New Urbanization is an inevitable choice in the process of urbanization in China. Focusing on the topics of green innovation and new urbanization, much work has been done to find their factors respectively while the relationship between the two remains to be explored. Hence, in this article, representative indicators of new urbanization and green innovation are selected to study the Yangtze River Delta City Group from the perspective of both the entire urban agglomeration and a single city, in terms of time and space, using the entropy method and the coupling model. The results show that (1). Green innovation promotes the new urbanization development and there is a synergistic effect between the two systems. (2). The level of economic development is an important factor that affects the degree of coupling degree and coordination degree between the two interactions, and its influence is better than the spatial effect. (3). Green innovation and new urbanization have positive spatial autocorrelation and regional agglomeration (there are High-High, Low-Low, and High-Low collections).
