Human settlement environment is space places closely related to human production and life, and also surface spaces inseparable from human activities. As a coastal city in the east of China, Qingdao has a relatively high level of urbanization. However, it also along with many urban problems at the same time, among which the problem of human settlement environment has attracted more and more general attention from people. According to the characteristics of human settlement environment in Qingdao, the research constructs an index system with 10 index factors from natural factors and humanity factors, and proposes a comprehensive evaluation model. Evaluate and grade suitability of human settlement environment in Qingdao, explore the spatial aggregation and differentiation of the quality of human settlement environment, and reveal the internal connection of spatial evolution. The results indicate that the overall livability of Qingdao is relatively good, showing a multi-center and radial driving development. The distribution of livability is uneven, showing a decreasing spatial distribution law from the coast to the inland, and the quality of human settlement environment in Jiaozhou Bay and the coastal areas is relatively high. Qingdao is mainly based on natural livability, supplemented by humanity livability, compared with natural suitability, the spatio-temporal evolution characteristics of humanity livability have experienced three stages: rising-contradictory rising-harmonious rising. The quality of human settlement environment has obvious spatial correlation and is positively correlated with the degree of agglomeration, and the agglomeration of blocks with a higher quality of human settlement environment is higher than that of blocks with a lower level. The rule of human settlement environment changing over time is that areas with high quality of human settlement environment begin to shift from the city center to the north and the south, transforming into multi-point development, and overall environmental suitability has been improved. According to the results of the comprehensive evaluation, combined with its local development status and policies, the research puts forward developmental suggestions for the construction of human settlement environment in Qingdao, and provides decision-making basis for relevant departments to solve the problem of deterioration of human settlement environment.

Groundwater is a major water resource in the North Chengdu Plain, China. The research objective is to determine the quality and suitability of groundwater for drinking purposes within the vicinity of a shallow, unconsolidated aquifer of Quaternary age. In this study, a detailed investigation was conducted to define the hydrochemical characteristics that control the quality of groundwater, based on traditional methods. Considering the uncertainties linked with water resources and the environmental complications, the fuzzy logic method was used in the determination of groundwater quality for more precise findings that support decision-making. To achieve such an objective, sixteen water quality guidelines were used to determine groundwater quality status in six selected wells. The results showed that the groundwater is neutral, very hard, and fresh in nature. Dominating cations and anions are in the order of Ca 2 + > Na + > Mg 2 + > K + and HCO 3 - > SO 4 2 - > Cl - . The Piper trilinear diagram demonstrates that the hydrochemical facies of groundwater are mostly of Ca-HCO 3 type. Statistical analysis denotes a positive correlation between most of the chemical parameters. The study took the results of the fuzzy logic evaluation method into consideration, to classify the samples into five groups according to the Chinese groundwater quality standard (GB/T 14848-93) for their suitability for domestic use. The results demonstrated that the quality of the groundwater samples is within grade II and III, and is suitable for drinking purposes. The comprehensive evaluation of groundwater quality is critical to aid sensitive policy decisions, and the proposed approach can guarantee reliable findings to that effect. The results of this study would also be helpful to future researches related to groundwater quality assessment.

The Brazilian livestock is predominantly extensive, with approximately 90% of the production being sustained on pasture, which occupies around 20% of the territory. In the current climate change scenario and where cropland is becoming a limited resource, there is a growing need for a more efficient land use and occupation. It is estimated that more than half of the Brazilian pastures have some level of degradation; however there is still no mapping of the quality of pastures on a national scale. In this study, we mapped and evaluated the spatio-temporal dynamics of pasture quality in Brazil, between 2010 and 2018, considering three classes of degradation: Absent (D0), Intermediate (D1), and Severe (D2). There was no variation in the total area occupied by pastures in the evaluated period, in spite of the accentuated spatial dynamics, with a retraction in the center-south and expansion to the north, over areas of ​​native vegetation. The percentage of non-degraded pastures increased ~12%, due to the recovery of degraded areas and the emergence of new pasture areas as a result of the prevailing spatial dynamics. However, about 44 Mha of the pasture area is currently severely degraded. The dynamics in pasture quality were not homogeneous in property size classes. We observed that in the approximately 2.68 million properties with livestock activity, the proportion with quality gains was twice as low in small properties compared to large ones, and the proportion with losses was three times greater, showing an increase in inequality between properties with more and less resources (large and small, respectively). The areas occupied by pastures in Brazil present an unique opportunity to increase livestock production and make available areas for agriculture, without the need for new deforestation in the coming decades.

Quarrying C Mining Activities, which are carried out by residents in the river area in Majalengka Regency, are mining sand individually or in groups in the form of traditional micro and medium enterprises. The existence of the business is carried out with various limitations namely minimal technology, the existence of limited human resources, small capital aspects and activities carried out by ignoring the licensing factor by referring to Law Number 4 of 2009 concerning Mineral and Coal Mining. Traditional miners must have a People's Mining License (IPR) granted by the local Regional Government. The fact is that the mining activities are carried out without a permit and public policies are needed from the continuous support of the local government to maintain the environmental quality of the river basin. The formulation of the problem is how is the implementation of Majalengka District Government's policy to maintain the quality of the river's environmental quality? And how is the legal understanding of traditional illegal miners in the District of Palasah Majalengka Regency to build awareness and legal compliance? This study uses the hermeneutic paradigm with the aim of understanding the interaction of actors who are involved or involved themselves in a social process, including social processes that are relevant to legal issues. The so-called actors in this research are the traditional illegal miners in Palasah Sub-District, Majalengka Regency. The legal basis for local community control of sand mining activities carried out naturally and is handed down for more than 50 (fifty) years. However, the legal basis for the control is not enough, in this case the people conducting sand mining must have a People's Mining License (IPR) granted by the local government as regulated in Article 1 paragraph (10) of Law No. 4 of 2009 concerning Mineral and Coal Mining.Kegiatan Penambangan Galian C, yang dilakukan oleh penduduk di kawasan sungai di Kabupaten Majalengka yaitu penambangan pasir secara perorangan atau berkelompok dalam bentuk usaha kecil mikro dan menengah secara tradisional. Eksistensi usaha tersebut dilakukan dengan berbagai keterbatasan yaitu minim teknologi, keberadaan sumber daya manusia yang terbatas, aspek permodalan kecil serta kegiatan yang dilakukan dengan mengabaikan faktor perizinan dengan merujuk kepada Undang-Undang Nomor 4 Tahun 2009 tentang Pertambangan Mineral dan Batu Bara.  Penambang tradisioanl harus mempunyai Izin Pertambangan Rakyat (IPR) yang diberikan oleh Pemerintah Daerah setempat. Faktanya aktivitas penambangan tersebut, dilakukan tanpa adanya izin dan dibutuhkan kebijakan publik dari keberpihakan Pemerintah Daerah setempat secara berkesinambungan untuk menjaga kualitas lingkungan hidup kawasan sungai. Rumusan masalahnya bagaimanakah implementasi kebijakan Pemerintah Daerah Kabupaten Majalengka untuk menjaga kualitas mutu lingkungan hidup sungai? Dan bagaimanakah  pemahaman hukum penambang liar tradisional di Kecamatan Palasah Kabupaten Majalengka untuk membangun kesadaran dan kepatuhan hukum? Penelitian ini menggunakan paradigma hermeneutika dengan tujuan untuk memahami interaksi para aktor yang tengah terlibat atau melibatkan diri ke dalam suatu proses sosial, termasuk proses-proses sosial yang relevan dengan permasalahan hukum. Yang disebut aktor dalam penelitian ini adalah para penambang liar tradisional yang ada di Kecamatan Palasah Kabupaten Majalengka. Dasar hukum penguasaan oleh masyarakat lokal atas kegiatan penambangan pasir yang dilakukan yang terjadi secara alamiah dan turun temurun selama 50 (lima puluh) tahun lebih. Akan tetapi, dasar hukum penguasaan tersebut tidaklah cukup, dalam hal ini masyarakat yang melakukan penambangan pasir harus mempunyai Izin Pertambangan Rakyat (IPR) yang diberikan oleh Pemerintah Daerah setempat sebagaimana yang diatur  dalam Pasal 1 ayat (10) Undang-Undang No. 4 Tahun 2009 tentang Pertambangan Mineral dan Batu Bara
