Multifunctional zoning is the primary basis for developing differentiated spatial planning systems and management policies of territorial spaces. The purpose of the paper is to generate an integrated multifunctional zoning scheme of the territorial space in Panxi by employing the functional significance assessment funded on the niche theory and its measurement models, in order to benefit the high efficiency land utilization and other socioeconomic development initiatives, such as the industrial poverty alleviation and mountainous urbanization in the regional scale. In this paper, the six main functions of territorial space were selected and the corresponding index systems were established for the Panxi Area. First, the significances of six territorial functions were evaluated using two niche models. Second, the K-means clustering method was employed to cluster the functional significance grades, acquiring the integrated multifunctional zoning scheme after qualitative adjustment. The results showed that the spatial distribution characteristics of the functional significance for territorial spaces were different. Prominent regions with higher functional significance of agricultural production were concentrated in the vicinity of the Anning River Basin. The distributions of higher significance for industrial development and mineral resources supply functions were correlated with the overall economic development in the Panxi Area. The regions with higher functional significance for tourism & leisure showed advantages on tourist attractions’ quality. The regions with higher significance for habitat service and ecosystem services functions presented advantages on good livability and ecological conditions. The integrated multifunctional zoning scheme for territorial space was highly in consistence with the Major Function Oriented Zoning of Sichuan Province and the “Thirteen Five” Development Plan for Panxi Economic Zone. Generally, the results indicated the rationality and feasibility of the research method, which provides a theoretical basis for coordinating and shaping the structure and pattern of territorial spaces, especially in the mountainous environment with distinct geographical as well as functional differences.

In order to meet the growing food demand of the global population and maintain sustainable soil fertility, there is an urgent need to optimize fertilizer application amount in agricultural production practices. Most of the existing studies on the optimal K rates for apple orchards were based on case studies and lack information on optimizing K-fertilizer management on a regional scale. Here, we used the method of combining meta-analysis with the K application rate-yield relationship model to quantify and summarize the optimal K rates of the Loess Plateau and Bohai Bay regions in China. We built a dataset based on 159 observations obtained from 18 peer-reviewed literature studies distributed in 15 different research sites and evaluated the regional-scale optimal K rates for apple production. The results showed that the linear plus platform model was more suitable for estimating the regional-scale optimal K rates, which were 208.33 and 176.61 kg K ha−1 for the Loess Plateau and Bohai Bay regions of China, respectively. Compared with high K application rates, the optimal K rates increased K use efficiency by 45.88–68.57%, with almost no yield losses. The optimal K rates also enhanced the yield by 6.30% compared with the low K application rates.

The evaluation of mineral resources development efficiency is a typical multicriteria decision-making issue. Meanwhile, due to the limited existing technology, there might be subjectivity, ambiguity, and inaccuracy of the measurement of the evaluation index of mineral resources development efficiency. In this paper, we, considering the incomplete information, use the hesitant fuzzy linguistic approach to describe the psychological hesitation and ambiguity of the decision-maker in the actual evaluation process and then construct the general model of the development efficiency evaluation of the mineral resources by using the hesitant fuzzy linguistic terms sets and modified TODIM. Finally, this paper takes the Panxi area as an example to study the development efficiency of vanadium-titanium magnetite. The results show that the hesitant fuzzy linguistic multicriteria decision-making (MCDM) approach can be implemented to mineral resources evaluation and resources management.

The objective of this study was two-fold, firstly, it analysed industrial development trends and deceleration across major Indian states since 1980-81 and, investigated industrial development in Punjab, a mineral resources deprived and a land-locked state. It was important as the policy changed at the national level in 1991 and removed various benefits for industrial development in mineralresources deprived regions and economically backward regions. To analyse the objective, both primary as well as secondary information was used. Findings of the study highlighted that industrial restructuring took place across major states in India during 1980-81 to 2017-18. In general, economically poor states and mineral resources deprived states witnessed the deceleration of the industrial sector. The position of the industrial sector in Punjab declined as compared to other states and compared to its past. The discussions with various stakeholders, including sampled industrial units, representatives of industrial associations, etc., highlighted various economic and non-economic factors behind the ongoing industrial deceleration in Punjab.

Groundwater is among the most important freshwater resources. Worldwide, aquifers are experiencing an increasing threat of pollution from urbanization, industrial development, agricultural activities and mining enterprise. Thus, practical actions, strategies and solutions to protect groundwater from these anthropogenic sources are widely required. The most efficient tool, which helps supporting land use planning, while protecting groundwater from contamination, is represented by groundwater vulnerability assessment. Over the years, several methods assessing groundwater vulnerability have been developed: overlay and index methods, statistical and process-based methods. All methods are means to synthesize complex hydrogeological information into a unique document, which is a groundwater vulnerability map, useable by planners, decision and policy makers, geoscientists and the public. Although it is not possible to identify an approach which could be the best one for all situations, the final product should always be scientific defensible, meaningful and reliable. Nevertheless, various methods may produce very different results at any given site. Thus, reasons for similarities and differences need to be deeply investigated. This study demonstrates the reliability and flexibility of a spatial statistical method to assess groundwater vulnerability to contamination at a regional scale. The Lombardy Plain case study is particularly interesting for its long history of groundwater monitoring (quality and quantity), availability of hydrogeological data, and combined presence of various anthropogenic sources of contamination. Recent updates of the regional water protection plan have raised the necessity of realizing more flexible, reliable and accurate groundwater vulnerability maps. A comparison of groundwater vulnerability maps obtained through different approaches and developed in a time span of several years has demonstrated the relevance of the continuous scientific progress, recognizing strengths and weaknesses of each research.

This article examines the social and environmental costs of living in the mineral age, wherein contemporary global livelihoods depend almost completely on the extraction of mineral resources. Owing to the logic of extractivism—the rapid and widespread removal of resources for exchange in global capitalist markets—both developed and developing countries are inextricably entangled in pursuing resource extraction as a means of sustaining current lifestyles as well as a key mechanism for promoting socioeconomic development. The past 15 years has seen a massive expansion of mineral resource extraction as many developing countries liberalized their mining sectors, allowing foreign capital and mining companies onto the lands of peasant farmers and indigenous people. This mining expansion has also facilitated the rise of artisanal and small-scale mining (ASM). Transformations in livelihoods and corporate practices as well as the environmental impacts and social conflicts wrought by mining are the central foci of this article.

In the coming years, the mine of LLC "Rudnik Valunisty" developing the gold and silver Valunistoe and Gornoye deposits will exhaust economically justified reserves. One of the ways to extend the life of the mine and increase the profitability of production should be the extraction of man-made secondary mineral resources. The purpose of the study is to identify the main types of solid and hydromineral form of technogenic-mineral formations at the Valunistoe Deposit, as well as to estimate the possibility of their industrial development. The useful components content was determined and calculated. The results of theoretical modeling of physical and chemical parameters of hypergenic mineral formation of the solid part of technogenic-mineral formations are shown. Objects of formation of technological waters are given. The conditions of concentration of gold and other metals are considered.

Porous medium burners are characterized by high efficiency and good stability. In this study, a new burner was proposed based on the combustion mechanism of the methane-air mixture in the porous medium and the preheating effect. The new burner is a two-section and double-deck porous medium with gas inlets at both ends. A mathematical model for the gas mixture combustion in the porous medium was established. The combustion performance of the burner was simulated under different equivalence ratios and inlet velocities of premixed gas. The methane combustion degree, as well as the temperature and pressure distribution, was estimated. In addition, the concentrations of emissions of NOx for different equivalence ratios were investigated. The results show that the new burner can not only realize sufficient combustion but also save energy. Furthermore, the emission concentration of NOx is very low. This study provides new insights into the industrial development and application of porous medium combustion devices.

Astrotourism is considered to be a modern form of ecotourism. The main resource for astrotourism is a high-quality night sky, but this is very sensitive to natural as well as anthropogenic factors; for example, land utilization and expansion of urban areas often cause the negative effect of light pollution. The aim of the study is to perform a lighting survey by night sky brightness (NSB) measurements using the sky quality meter (SQM-L) at 20 study sites of the Slovenské stredohorie Upland region (Slovakia) and to assess the region’s potential for astrotourism development (PAD) using a multicriteria analysis. The NSB values ranged from 19.90 (city Žiar nad Hronom at Žiarska kotlina Basin) to 21.54 mag/arcsec2 (recreation area Poľana at Poľana Mountains). At 14 out of 20 study sites, the NSB values even reached 21.2 mag/arcsec2, as recommended by the International Dark-Sky Association for dark-sky parks. Four study sites were categorized as sites with medium PAD, and sixteen with low PAD. No study site reached a high or very high PAD. The best conditions for astrotourism development are fulfilled mainly by the Poľana Mountains geographical unit. The findings can be used for sustainable astrotourism development, land management, and planning to ensure socioeconomic development, together with nature and dark-sky conservation.

<p>The rare earth elements (REEs) are a group of seventeen metals including 15 lanthanides, scandium and yttrium.  These metals have been projected to be critical for future industrial development. However, India currently does not have any economic grade primary deposit of REEs; all of India’s production comes from monazite-bearing beach sands along the eastern and western coasts that have been derived from REEs-enriched continental rocks such as pegmatites or carbonatites. This contribution documents a GIS-based prospectivity model for exploration targeting of REE associated with carbonatites and alkaline-complexes in the geologically permissive tracts of NW India comprising parts of western Rajasthan and northern Gujarat. A mineral systems approach is applied to model the key ingredients of an REE system including geodynamic setting; fertile mantle/crustal sources of REEs; deep to shallow crustal architecture; and REE deposition.  This conceptual genetic model of REE mineral systems is, in turn, used to identify the key regional-scale REE-deposit targeting criteria in NW India. Regional-scale multi-parametric exploration datasets are processed to represent the targeting criteria in form of predictor GIS layers. Finally, an expert-driven fuzzy inference system is designed for delineating and raking prospective REE targets. Simultaneously, the stochastic and systemic uncertainties in the prospectivity modeling are modelled to delineated (a) high priority REE exploration targets areas with low uncertainty and high prospectivity for immediate ground follow up and (b) areas with high uncertainty and high prospectivity for further data acquisition in order to reduce uncertainty.</p>
