The influence of water source protection zone delimitation on development in Huanren Manchu Autonomous County

Under the background of rapid urbanization and industrialization development, in order to satisfy the increasing demand of residents for domestic water, the establishment of water source protection zone is the most effective way to protect water resources at present. However, the influence on the social and economic development could not be ignored. The article analyzes the influence of the delimitation of water source protection zone on economy such as ecological migration, urban municipal pipe network construction, rural drinking water and urban water supply. The impact on economy like industrial enterprises, agricultural planting, livestock industry, aquaculture, tourist industry were also mentioned. The article triggers the exploration of the way to realize the coordination and sustainable development of economy, society, resources and environment

The Island Sea Problem

Significant changes are taking place in the environment of our planet today as a result of the negative impact of human activities. In particular, climate change and various natural disasters are felt in all latitudes of the planet. As a result, forested areas are shrinking, polluting the atmosphere, water and lithosphere. The document provides for the creation of conditions for investment in the creation and implementation of high-tech innovations, environmentally friendly, energy and water-saving technologies, the widespread use of “green economy”, prevention of soil degradation, desertification and ecological migration, ecotourism.

Eyes Everywhere: Ecological Migration and State Surveillance in the Age of Iron Man

In today’s society, migrants/citizens are monitored and exploited. A comprehension of the complexity of surveillance and resistance to it is crucial to guarantee a more democratic community. Disciplinary societies (in the Foucauldian context) have moved beyond the panopticon’s ecologies. Today’s monitoring is reterritorialized. Surveillance, enabled by digitalization, can adapt to any room today, but with the constant change in spaces, simply monitoring human actions would be inadequate. It is necessary to monitor both behavior and geographical place. Surveillance is also increasingly being marketed. Products are now being sold on the basis of people’s private lives. This dual aspect of surveillance connected to “safety” and “company” is well suited to the neo-liberal agenda. But monitoring also needs the supervised to participate. The States and MNCs are in a challenging situation if and when the monitored resist surveillance. Efforts are still being made by the state and its technology to properly monitor ecological migrations. This study claims that it is ecological and migration surveillance that makes Iron Man a strong avenger. Yet there are several cases in which his surveillance is inefficient through the cinematic narrative. For those already oppressed and who resist surveillance, the study would investigate these moments as flashes of optimism. This study also attempts to enunciate some of the aspects derived from works by theoreticians like Gary Marx and David Lyon. With the collective will of surveillance, unethical monitoring of ecologies and migrations imposed on us, it can be resisted to a good extent.

Bryozoans from the early Cambrian Chengjiang Biota

Bryozoa are colonial, aquatic, generally sessile coelomate metazoans, with a retractable lophophore and U-shaped digestive tract. They are widely distributed and highly diverse in extant marine and freshwater environments. Current confident fossils of the earliest bryozoan only occur in the Early Ordovician, although molecular estimation date their origin in or prior to the early Cambrian, rendering the origin and early evolution of bryozoans are intensely debated. Here, we describe two cyclostomes, Panpipora yunnanensis gen. et. sp. nov. and Corynotrypa sp., having been recovered from the Cambrian Chengjiang Biota (~ 518 m.y.) in Southwest China. The bryozoans represent the earliest fossils of Bryozoa, predating the record of the phylum by more than 30 million years. Our finding reveals that the Bryozoa, as all other skeletonised metazoans, first evolved during the Cambrian Explosion, and it is congruent with estimation of molecular clock that the cyclostomes is the earliest biomineralised clade. Corynotrypa might be derived from unmineralized ctenostomes by stolonal mineralization and change of growth direction of polypides from vertical to creeping. The unmineralised frontal exterior wall might be a share character existed in all ancestral clades. Encrusting specimens that inhabited in muddy environments have been confirmed here, further suggesting that encrusting bryozoans underwent a profound ecological migration from soft- to hard-bottom facies from Cambrian to Ordovician.

Evaluation of the Types and Comprehensive Effects of Ecological Migration in China: Taking the Ecological Protection and Land Tenure Protection of Xihaigu Area in Ningxia as an Example

The ecological migration project in the Xihaigu Area of Ningxia, the first of such projects to be initiated with the longest history, is a typical example of China's ecological migration projects. Through the methods of field investigation, in-depth interviews, and examination of typical cases, the paper aims to evaluate Xihaigu's ecological migration project in the aspects of ecological restoration, poverty alleviation, income increase and social development. The conclusion is that China's ecological immigrants represented by Xihaigu's example have reached ecological improvement goals and economic and social development. At the same time, due to the government's vigorous promotion of this process, the fairness of the distribution of benefits for migrants in the earlier and later stages is slightly unbalanced, and the ecological protection awareness of the immigrants was always insufficient. The later process of immigration was relatively too fast, and ecological migration still faces further challenges.

Land Cover Mapping and Ecological Risk Assessment in the Context of Recent Ecological Migration

In order to protect the ecological environment and solve the poverty problem in the western region, China has established an ecological migration (EM) policy. This policy aims to relocate populations from poverty-stricken areas with fragile ecological environments, which inevitably leads to changes in land cover and the ecological environment. The objective of this study was to identify the effects of EM in a typical region (Wuwei), including changes in the land cover and ecological risk (ER). A land cover change monitoring method was implemented for the 2010–2019 period for six land cover classes using random forest, which is an effective supervised machine learning method. The land cover change patterns were analyzed by determining the area changes of the six classes and applying a land use transition matrix, and a landscape ecological risk model based on landscape disturbance and fragility was used. Our results demonstrate that the increase and decrease in the area of cultivated land, unused land, and construction land can be divided into two stages (2010–2015 and 2015–2019). The area of water and perennial snow doubled during the study periods. The major land cover transitions were between unused land and construction land and between unused land and crop land. In addition, the ER value for the Qilian Mountain National Nature Reserve decreased because of the implementation of EM in the study area, indicating that the ecological environment was effectively improved. The results demonstrate the advantage of the proposed approach in understanding the impact of EM on regional land cover changes and the ecological environment so as to provide guidance for follow-up planning and development.

Environmental migration and country security: Theoretical analysis and empirical research

The article considers the impact of environmental changes on population migration and security of countries. Theoretical aspects of Environmental migration, in particular its essence and types, are studied. The main directions of scientific research in this field are considered. In particular, much attention is about finding ways to adapt to changes in the environment and minimize the negative consequences of these changes to achieve sustainable development in both regions and countries. The study found that internal population movements are mainly due to climatic factors such as storms and floods. It was determined that in 2019, about 52% of new mixing was caused by storms and 40% - by floods. Countries for which the phenomenon of ecological migration is most characteristic are India, the Philippines, the United States, China, and Indonesia. The main problems that arise in the study of Environmental mobility of the population are identifiedThey are mainly related to the lack of information and statistical base for conducting qualitative and diverse research.

ECOLOGICAL MIGRATION FROM CENTRAL ASIA TO RUSSIA

Developing countries and low-income countries with rapidly growing populations and underdeveloped agricultural technologies are most vulnerable to climate change and natural disasters. The countries of Central Asia are already exposed to the impact of natural and climatic changes due to insufficient financial and technical capabilities to overcome negative climatic and environmental phenomena. The authors predict an increase in the ecological migration of the population from Central Asia to Russia due to the visa-free regime, territorial proximity, established migrant social networks and other factors, which partially will compensate for the Russian population decline. Without a legal channel for environmental migration, these flows will be forced to use the labor migration channel. However, there are a number of potential negative consequences that need to be further scrutinized.

Migrant adolescents’ behavioral problems compared to host adolescents and adolescents in their region of origin: a longitudinal study

Background Since the 1990s, families from the ecologically hostile mountainous southern areas of Ningxia Province, China, have been migrating to the northern areas of the province. This study compared the prevalence of behavioral problems among migrant adolescents to those among host adolescents (adolescents from the northern areas) and adolescents in the region of origin (adolescents from the southern areas), to determine whether ecological migration is related to adolescent behavioral problems, and possible changes in such problems over time. Methods We used the Children and Adolescents Ecological Migration Survey on Mental Health, administered to 4805 students aged 12–16 years and their parents between 2012 and 2014 (W1), of whom 1753 students and their parents completed the follow-up between 2014 and 2017 (W2). Parents answered questions related to adolescent behavioral problems, main source of family income, parents’ desire to reverse migrate, improved standard of living, and parents’ educational attainment, while children completed the Eysenck Personality Questionnaire and a classroom environment questionnaire. Results The prevalence of behavioral problems among the migrant adolescents (28.04%) was significantly higher than among host adolescents (21.59%) or adolescents in the region of origin (24.37%; p < 0.001) at W1. After adjusting for gender and age, parents’ work outside the home was the main source of family income (OR = 1.42, 95% CI = 1.13–1.78), and adolescents’ learning burden (OR = 1.04, 95% CI = 1.01–1.06) in school negatively influenced behavioral problems. Strong student-teacher relationships (OR = 0.97,95% CI = 0.94–0.99) and parents who had no intention to move back to the original residence (OR = 0.70, 95% CI = 0.52–0.94) exerted a protective effect at W1; at W2, a protective effect was associated with improved living conditions (OR = 0.39–0.55, 95% CI = 0.25–0.84). The extent of behavioral problems among migrant adolescents significantly decreased after two years. Conclusion Ecological migration will increase children’s behavioral problems in the early stage, with various factors influencing the extent of these problems.
