Inter-Generational Occupational and Socio-Economic Pattern of Bhutias in Sikkim: Case Study of Lachung, Tashiding and Tathangchen

The paper discusses the inter-generational occupational and socio-economic pattern of Bhutias in Sikkim. Case studies of certain Bhutia families were conducted as an oral source for understanding their present status, changing lifestyle and their self perception about the present status. Bhutia families from three Bhutia dominated villages Lachung, Tashiding and Tathangchen in Sikkim were interviewed. The findings reveal that transformations and diversification in the occupational pattern among the Bhutia families in Sikkim has taken place. Agriculture as their traditional occupation has declined as they are pursuing other alternative occupations. The case study shows that the number of Bhutia agricultural households, both as agriculturist and agricultural labour has declined, but they continue as owners of large land plots. The study sheds light on the occupational shift from traditional occupations to business and trade, tourism, and salaried jobs over the years and generations.

Recent enrichment of megafauna in the north of Eurasia supports the concept of Pleistocene rewilding

‘Pleistocene rewilding' refers to the concept of restoring ecosystems to their state during the Pleistocene epoch, by (re‐)introducing species or their close relatives that were present during that time, in an effort to revive ecological processes that existed before human‐driven extinctions. This concept is highly controversial for both ethical and ecological reasons. Here I review evidence of recent northward range expansions of various large land mammals in boreal Eurasia, and discuss whether this provides evidence that rewilding projects might be justified and feasible. Around 100 years ago, the native boreal fauna of Eurasia included five species of large land mammals: moose Alces alces, brown bear Ursus arctos, wolf Canis lupus, reindeer Rangifer tarandus, and snow sheep Ovis nivicola, but since then the list has expanded. This is due to the introduction of bison Bison bonasus, Bison bison, muskox Ovibos moschatus, non‐native deer, and feral horses, as well as the northward expansion of wild boar Sus scrofa, roe deer Capreolus capreolus, Capreolus pygargus, and red deer Cervus canadensis. In addition, several southern species temporarily occurred in the north, including tiger Panthera tigris, sika deer Cervus nippon, and yak Bos grunniens. This ongoing enrichment of the boreal fauna is reminiscent to Pleistocene rewilding. However, so far, the abundance of expanding large mammals species remains low. Large‐scale projects on Pleistocene rewilding are labor‐intensive, expensive, and not popular enough to receive support, and therefore their realization is problematic

Effect of calculation unit division in distributed hydrological models on the analysis of hydrological effects of land use change

Numerous papers have utilized distributed hydrological models to assess the hydrological effects of land use changes. However, can these models reflect actual land use changes? This study focuses on the effect of calculation unit division in distributed hydrological models on the analysis of hydrological effects of land use change. The Soil and Water Assessment Tool (SWAT) model is tested here, using the Dongjiang headwater region in southern China as the study area. Thirteen calculation unit division schemes are developed to analyze the effects of land use generalization caused by calculation unit division on runoff and sediment load simulations by SWAT. Two indices, including Land Use Identification Accuracy (LUIA) and Land Use Change Identification Accuracy (LUCIA) are employed to quantify the model’s precision in describing land use and changes under various scenarios. In addition, this study examines how differences in land use descriptions, resulting from calculation unit division, influence the hydrological effect of land use changes in the SWAT model. The findings indicate that: (1) Calculation unit division leads to the generalization of land uses identified by the SWAT model. As the sub-watershed Drainage Area Threshold (DAT) increases, the small land use types tend to aggregate into the larger land use types. (2) Land use generalization, resulting from calculation unit division, significantly affects runoff and sediment load simulations. An increase in DAT induces a significant rise in simulated runoff and sediment load (P<0.001). (3) Calculation unit division substantially impacts the model’s description of land use. LUIA and LUCIA show a significant downward trend as DAT increases. (4) Calculation unit division significantly alters the analysis results of hydrological effects of land use changes. Different calculation unit division schemes yield different analysis results of hydrological effects of land use changes. These results demonstrate that the division of calculation units in the SWAT model leads to land use generalization, which impacts the model’s description of land use changes and subsequently affects the assessment of the hydrological effects of land use changes. The research results imply that when analyzing the hydrological effects of land use change, a more refined calculation unit division scheme should be adopted as far as possible to improve the accuracy of model’s description of land use change and reduce the uncertainty of model simulation results.

No right of prescription. debt recovery for luxury goods in Moldova at the end of the 16th century and the beginning of the 17th century

Political elites in Moldavia have always had a fondness for luxury items. Even from the beginning of Moldavia’s political existence the merchants who passed through these territories conducted extensive trade-work in this area and among those targeted in such activities were also Moldavian boyars. Having large dominion lands, Moldavian boyars managed to achieve significant profits by selling the goods they had obtained on their fields. Often, the commercial activities were performed on the basis of credit and the goods were purchased under further obligations. The study examines such a case during the reign of Iancu Sasul when Lupul Stroici bought several luxury items from some Greek merchants. The payment for them would be claimed in a few decades from his sons by Bernardo Borisi. In the process will also be involved Moldavia’s incumbent Metropolitan bishop Anastasie Crimca, who would redeem and pay down debt villages for the Moldavian boyar.

The influence of the industrial organization on farmers' willingness to adopt water-saving irrigation technologies: a perspective of organizational support

ABSTRACT Water scarcity and inefficiency hinder China's sustainable agriculture. Water-saving irrigation (WSI) technology, as a crucial means to improve water efficiency, has relatively low adoption rates. In this context, this study utilizes survey data from 1,178 farmers in the Yellow River Basin in China, employing both the Binary Probit model and the Iv-Probit model to deeply explore the influence and mechanism of industrial organizations on farmers' willingness to adopt WSI technology. Our study shows that organizational participation behavior and degree of organizational support can effectively enhance farmers' willingness to adopt WSI technology. Organizational support indirectly enhances farmers' willingness to adopt WSI technology by standardizing production, providing agricultural training, and being proactive in learning agricultural techniques. Furthermore, organizational support has a significant impact on farmers with low education, young age, large land management areas, and poor agricultural production conditions. Our study also found that organizational support and government support can play a synergistic role in promoting farmers' willingness to adopt WSI technology. Therefore, it is necessary to strengthen the cultivation of industrial organizations, improve the governance structure of industrial organizations, strengthen the institutional guarantee of industrial organizations, and pay attention to the heterogeneity of farmer groups when leveraging the role of industrial organizations.

Informal Settlements: A New Understanding for Governance and Vulnerability Study

This review examines current knowledge in the literature on informal settlements, specifically those contributions that include emphases on governance and the role of public administration. Given that informal settlements task the public sector with specific challenges that test the limits of infrastructure, while also presenting considerable human demands, there is a need to better understand how informal settlements and governments’ capacities to respond to such phenomena potentially deepen concerns with already vulnerable populations. After an introduction to the concept of informal settlements, the paper considers the approach to the literature review, which included an initial group of 272 papers from peer-reviewed, English-language journals, from the period 2019 to June 2024. Major themes are discussed, with opportunities for future research identified. Informal settlements are still an emerging topic within the larger land use and urban planning literature, but the significance of this research extends beyond the immediate areas of the settlements themselves to critical areas of governance and vulnerability study.

Analysis of the development of organic crop production in Latin America

The paper is devoted to the study of the process of development of organic production as a global trend in agriculture. The objects of the research are the countries of Latin America, as territories that are promising in terms of large-scale and rapidly developing organic agriculture for export and domestic consumption — Uruguay, Paraguay, Brazil, Argentina, Chile, Mexico, Dominican Republic. The countries have large land funds and favorable agroclimatic conditions in most of their territories. In the work, based on the application of methods of time series alignment and the graphical method, trends in demand for the purchase and subsequent use of pesticides, the prevalence of malnutrition in Latin America and in the world, as well as prospects for the development of organic crop production by such an indicatosr as the total area of organic lands and number of producers are identified. The simple linear regression model constructed by the authors made it possible to establish the relationship between the volumes of greenhouse gas emissions and the average annual temperature, which made it possible to establish the need to reduce the use of synthetic fertilizers and pesticides to achieve sustainable development goals. Calculation of the linear and quadratic coefficients of structural shifts, as well as the index of differences, made it possible to identify structural changes in priority groups of crops for growing organic crops.

A new species of alien land flatworm in the Southern United States.

Specimens of a flat and dark brown land planarian were found in a plant nursery in North Carolina, USA in 2020. On the basis of examination of photographs of the live specimens only, the specimens were considered as belonging to Obama nungara, a species originally from South America, which has now invaded a large part of Europe. Unexpectedly, a molecular analysis revealed that the specimens did not belong to this species, neither to the genus Obama. We then undertook its histological study, which finally confirmed that the species is a member of the genus Amaga: the species is herein described as a new species, Amaga pseudobama n. sp. The species has been found in three locations in North Carolina and some infested plants were from Georgia. We reinvestigated specimens collected in Florida in 2015 and found that they also belong to this species. Citizen science observations suggest its presence in other states. Therefore, it is likely that A. pseudobama has already invaded a part of south-east USA and that the invasion took place more than ten years ago. The complete 14,909 bp long mitochondrial genome was obtained. The mitogenome is colinear with those of other Geoplanidae and it was possible to find and annotate a tRNA-Thr, which has been reported missing in several geoplanids. Amaga pseudobama shares with other Geoplaninae the presence of alternative start codons in three protein-coding genes of its mitogenome. The availability of this new genome helped us to improve our annotations of the ND3 gene, for which an ATT start codon is now suggested. Also, the sequence of the ATP6 gene raised questions concerning the use of genetic code 9 to translate the protein-coding genes of Geoplanidae, as the whole translated protein would not contain a single methionine residue when using this code. Two maximum likelihood phylogenies were obtained from genomic data. The first one was based on concatenated alignments of the partial 28S, Elongation Factor 1-alpha (EF1) and cox1 genes. The second was obtained from a concatenated alignment of the mitochondrial proteins. Both strictly discriminate A. pseudobama from O. nungara and instead associate it with Amaga expatria. We note that the nine species currently accepted within Amaga can be separated into two groups, one with extrabulbar prostatic apparatus, including the type species A. amagensis, and one with intrabulbar prostatic apparatus, including the new species A. pseudobama. This suggests that species of the latter group should be separated from Amaga and constitute a new genus. This finding again illustrates the possible emergence of new invasive species in regions naturally devoid of large land planarians, such as North America. Amaga pseudobama thus deserves to be monitored in the USA, although its superficial resemblance to O. nungara and Geoplana arkalabamensis will complicate the use of photographs obtained from citizen science. Our molecular information provides tools for this monitoring.

The potential of silvopasture in California: producer perspectives

ABSTRACT Silvopasture is a form of agroforestry that has been practiced around the globe for millennia and involves integrating trees, livestock, and forage within the same area. Recent increased attention and research on this practice has provided greater evidence that it can deliver both economic and environmental benefits, including climate mitigation and adaptation. However, it is not widely used in the United States. The objective of this study was to gain a better understanding of the current state of silvopasture and opportunities for expansion of this practice in California, one of the primary agricultural regions in the United States. California is geographically suited to silvopasture and already has large land areas dedicated to both orchards and grazing though these two types of agriculture are typically managed and documented separately. We report the results of our statewide survey of silvopasture producers, including benefits, motivations, and challenges associated with this practice. Finally, we recommend ways in which the barriers to silvopasture adoption could be reduced.

Organized labour migration of residents of Lithuania to the USSR in the sixth–ninth decades of the 20th century

Referring to archive and historiographic materials, in this paper problematics of labour migration to the USSR from Lithuania in 1953-1984 is analysed. Attention is drawn to migration directions, motivation of residents, quantitative indices, territorial aspects related to persons participating in labour migration process and social picture. Residents of Lithuania became participants of the campaign for organized all Soviet Union-wide labour force migration to participate in implementation of large and important land, forestry and industry projects. By the way, the residents of our Republic joined this campaign later than residents from other Republics – in 1953 only. Organized labour force migration from Lithuania to the USSR was of lower level that it had been planned in Moscow. The main directions of labour force migration were: 1) agriculture intensification program (virgin lands campaigns in Kazakhstan and Russia); 2) Russian forestry development program; 3) program of construction of gigantic transport and industrial objects in Russia (Siberia, etc.); 4) the “Third Semester” program – season-based works of students in industry and agriculture sectors of Russia, Kyrgyzstan, Uzbekistan and other Soviet Republics. In 6th-9th decades of the 20th century, about 75 thousand residents of Lithuanian Soviet Socialist Republic were sent to work in other regions of the Soviet Union; labour migrants worked on industrial objects, farms and forestry units. Mostly, they were men from urban areas, by ethnic composition – Russians and Lithuanians. The most intensive time period of sending to work as labour migrants was the 1953-1965 period, as at that time in Kazakhstan and Russia huge programs of economic development had been implemented (virgin lands campaign, forestry development). Namely during this period, over 80 per cent of residents of Lithuania who participated in this campaign were sent to labour destinations. Although in later years the migration campaign covered entire Lithuania, its scale diminished markedly. Due to certain national traits of Lithuanians (sedentary life, attachment to the land) and social-economic situation in the Lithuanian Soviet Socialist Republic (fast and intensive industry development ensuring quite good wages, well-developed social infrastructure, etc.), the residents of Lithuania liked to conclude short-term employment agreements, and after termination of these agreements made efforts to return to Lithuania and stay there not attracted by labour migration campaign anymore.

Tracing the Process of Rome's Expansion in Anatolia

As a result of Rome's nearly 60-year-long struggle that wore out the state, the Republican administration ended with Augustus. With this new system, large lands will now be governed by a single administrator. This new system brought the imperial structure to solve the problems of Rome. After Rome established a political authority and power in the Italian geography, a Roman-Italian union was established here. The policy followed by Rome this time in order to achieve the desired area of dominance was to explore areas of expansion outside Italy. As of the Roman period, it underwent changes in its area of expansion along with the changes in political structures and orders. In this context, it expanded its distribution area towards Anatolia. During the period when this expansion area took place, Rome experienced great struggles both externally and internally. Our study topic, "The Process of the Spread of Rome in Anatolia", contains cases and impressions that cannot be repeated due to the time period it covers. For this reason, criteria such as the content of the study, its field, and the time period to be researched are not suitable for quantitative research methods. Therefore, document analysis, one of the qualitative research methods that is thought to be more amenable to the criteria of the study, constitutes the method of the study. With this method, it was tried to reach various sources and documents about the policy followed by Rome in Anatolia and draw meaningful inferences from them.

Deep Learning for Pavement Condition Evaluation Using Satellite Imagery

Civil infrastructure systems cover large land areas and need frequent inspections to maintain their public service capabilities. Conventional approaches of manual surveys or vehicle-based automated surveys to assess infrastructure conditions are often labor-intensive and time-consuming. For this reason, it is worthwhile to explore more cost-effective methods for monitoring and maintaining these infrastructures. Fortunately, recent advancements in satellite systems and image processing algorithms have opened up new possibilities. Numerous satellite systems have been employed to monitor infrastructure conditions and identify damages. Due to the improvement in the ground sample distance (GSD), the level of detail that can be captured has significantly increased. Taking advantage of these technological advancements, this research evaluated pavement conditions using deep learning models for analyzing satellite images. We gathered over 3000 satellite images of pavement sections, together with pavement evaluation ratings from the TxDOT’s PMIS database. The results of our study show an accuracy rate exceeding 90%. This research paves the way for a rapid and cost-effective approach for evaluating the pavement network in the future.

디지털 헬스케어를 활용한 수원특례시 노인복지시스템 구축 연구

The pace of aging in Korea is the highest in the world, and Suwon City is also expected to enter a super-aged society in 2030, so preparations for the medical and welfare sectors for the elderly are urgent. In addition, interest in digital healthcare, which focuses on non-face-to-face treatment, has increased due to the COVID-19 pandemic crisis in 2019. In this study aimed to propose a plan to build an elderly welfare system for Suwon based on previous studies through literature review and expert focus group interviews As a result of literature survey, in developed countries, digital healthcare services have been developed mainly in the U.S., Japan, and Israel. In particular, the U.S., which has been promoting non-face-to-face telemedicine since early on due to its large land area, has developed a business centered on private companies, but has also been able to grow into a digital health powerhouse due to government support such as deregulation. In Korea, the development of the digital healthcare industry has been limited due to problems such as the regulation of telemedicine practices and unclear core. In addition, according to the results of the expert group interviews, those involved in the mobile healthcare project at the Suwon City Health Center pointed out errors in the system app and difficult input methods as the main factors for negative participation in the project. Therefore, it is expected that for self-healthcare through digital healthcare to be actively implemented, it is necessary not only for the right understanding and participation of the project targets, but also for the active cooperation of the government and private companies.

Spatiotemporal Assessment of Land Use System in Kathmandu Valley of Nepal Using Geospatial Techniques

The Kathmandu Valley is one of the growing urbanization trend spreading capital city of Nepal. This metropolitan valley is experiencing a significant transformation of its landscapes in the last few decades resulting in large land use and land cover change. A systematic study of the urbanization trend and LULC has been felt need on this valley. Considering the importance of LULC change this study is carried out using Arc GIS to assess land use system and change dynamics in the study area based on Landsat imagery of the years from 2000 to 2019 at yearly interval. From the study of LULC of Kathmandu valley over the period selected a remarkable change scenario was observed in Agricultural land, Forest area, Vegetation land, Built up and River Bed area. Built up area is found significantly increased by 16% during the period in Kathmandu Valley. Forest area is found increased by 3%, whereas because of concrete structures built in the city caused decrease in water body in the valley by 3% up to the year 2008 and found increased later years with the increase in forest area. The effects in rivers system are observed significantly. River bed area is found decreased over this time period by 9%.This study showed the fast expansion of urbanization area and rapid conversions of agricultural land in Kathmandu Valley (study area).

Pelatihan Pemanfaatan Limbah Kelapa Sawit Menjadi Pupuk Semi Organik Bagi Siswa Jurusan Agribisnis Tanaman Perkebunan SMKN 1 Kuok

In 2023, Riau's oil palm plantation area with cultivation status will reach 3.5 million hectares with palm oil production reaching 9.06 million tons (Ministry of Agriculture, 2023). This figure makes Riau Province the largest palm oil center province in Indonesia. As the area of oil palm plantations increases, palm oil waste will be produced consisting of empty bunches, fronds, shells and fiber. This palm oil waste can pollute the environment in water and soil and can also threaten biodiversity. One use of palm oil waste is compost. Organic fertilizer (compost) is the final and/or intermediate result of changes or decomposition of plant and animal parts and remains, for example cake, guano, bone meal, livestock waste and so on (Ege et al., 2018). The objectives of this PKM are given to students of SMKN 1 Kuok, namely 1) providing early knowledge about the use of palm oil waste, 2) understanding how to make compost from palm oil waste, and 3) socializing the facilities and infrastructure available at Kampar Polytechnic . Large land and facilities for making compost fertilizer are not available in the ATP department of SMKN 1 Kuok. So with this training in making compost fertilizer, we can overcome the problem of places and practicum areas that are not available at SMKN 1 Kuok.

COVID‐19 vaccine variety and dimensions of risks: What factors induced nations to introduce multiple vaccines?

AbstractAdding a new dimension to the body of research on COVID economics, this article considers the determinants of vaccine variety across nations. Driven by supply chain issues, development timelines, pricing, and vaccine nationalism, the number of available vaccines varies considerably across nations. Results show that greater pandemic severity and more populous nations had more vaccines, while nations with large land areas had fewer vaccines. Finally, while island nations were likely to have fewer vaccines, authoritarian regimes were mostly no different from other regimes. Greater COVID risks mostly lowered vaccine variety, as did supply chain issues and the prevalence of other infectious diseases. Finally, nations with worse institutional quality had more vaccines, ceteris paribus.

Construction of Large Dam: Thinking Dynamics and Struggle of Displaced People

In this modern era, mega development projects are largely responsible to bring about social change in rural community. These development interventions have direct or indirect impacts on the life of rural people. Dam construction for hydropower requires confiscation of large land and eventually displaces large number of people. Kulekhani hydropower project is one of few projects in Nepal that has its own reservoir unlike others which relies on run-off-the-river facilities. Thus being one of the large land acquiring project, it has displaced many people, of which, published works are not available regarding the social and cultural practices of displaced people in the aftermath of their displacement from original homeland. This study was conducted in 2018 on Kulekhani Hydropower Project focusing on the dam development from the perspective of psychological, social and cultural landscape of its affected people.This research is largely based on the primary data collected direct from the field study using biographical interview method, which cover the compensation they received and its utilization pattern, change in their old and new lifestyle and socio-economic status of the displaced people. Research shows that development projects displace people from their roots which cause lots of trouble in the beginning but gradually the displaced people develop the capacity to think according to new environment and with a new perspective which is obviously different that the one they had in their origin.

Prospects of cotton growing in the Caspian provinces of Iran in the assessments of officials of the Russian Empire on the eve and during the First World War

The article is devoted to the assessment of the prospects for the development of cotton growing in the Astarabad and Mazanderan provinces of Qajar Iran by the statesmen of the Russian Empire on the eve and during the First World War. The pre-war years were characterized by the intensification of Russian policy in the region. Among other things, with the active participation of the consulate in Astarabad, the formation of large Russian land ownership in the Caspian provinces and the development of peasant resettlement in the region is taking place. Cotton was considered as one of the main promising crops for breeding in the established farms, while it was the most interesting from the point of view of solving Russia’s strategic tasks to ensure the country’s resource independence. This problem is one of the little-studied in the existing historiography. On the basis of archival and published sources, the views of officials of the Ministry of Foreign Affairs and the Resettlement Department on the problem of cotton growing are investigated. It is shown that due to the favorable climatic conditions of the region and its natural resources, the prospects for cotton cultivation for the Russian market looked promising. The connection in the ideas of the officials of the Resettlement Department of the success of cotton growing with the development of Russian peasant resettlement, the influence of the ideas of the "civilizing mission" of Russia on their considerations is also noted.

Exploring PCSWMM for Large Mixed Land Use Watershed by Establishing Monitoring Sites to Evaluate Stream Water Quality

Extensive hydrologic and water quality modeling within a watershed benefits from long-term flow and nutrient data sets for appropriate model calibration and validation. However, due to a lack of local water quality data, simpler water quality modeling techniques are generally adopted. In this study, the monitoring sites were established at two different locations to collect hydraulic data for the hydraulic calibration and validation of the model. In addition, water quality samples were collected at eight monitoring sites and analyzed in the lab for various parameters for calibration. This includes total suspended solids (TSS), soluble phosphorus, five-day biochemical oxygen demand (BOD5), and dissolved oxygen (DO). The Personal Computer Storm Water Management Model (PCSWMM) 7.6 software was used to simulate all the pollutant loads using event mean concentrations (EMCs). The performance of the model for streamflow calibration at the two USGS gauging stations was satisfactory, with Nash–Sutcliffe Efficiency (NSE) values ranging from 0.51 to 0.54 and coefficients of determination (R2) ranging from 0.71 to 0.72. The model was also validated with the help of historical flow data with NSE values ranging from 0.5 to 0.79, and R2 values ranging from 0.6 to 0.95. The hydraulic calibration also showed acceptable results with reasonable NSE and R2 values. The water quality data recorded at the monitoring stations were then compared with the simulated water quality modeling results. The model reasonably simulated the water quality, which was evaluated through visual inspection using a scatter plot. Our analysis showed that the upstream tributaries, particularly from agricultural areas, were contributing more pollutants than the downstream tributaries. Overall, this study demonstrates that the PCSWMM, which was typically used for modeling urban watersheds, could also be used for modeling larger mixed land use watersheds with reasonable accuracy.

Dissolution behavior of aluminum and silicon from kaolinite diaspore symbiotic low-grade bauxite in low alkali system

China produces over 50 % of global alumina, but its dependence on imported bauxite is as high as 65 %. Local bauxite in China is of low grade. During mining, high-grade ores were sold, while low-grade ores were left piled up on site. This practice not only occupied a large land area but also caused serious pollution. Additionally, kaolinite and diaspore are embedded in a complex and dispersed distribution on the micron scale. The physical separation and ore phase dissociation of these two (kaolinite and diaspore) are very difficult, thereby preventing the economical and efficient utilization of Chinese bauxite using existing mineral flotation and sintering technologies. Based on the analysis of the molecular structure of kaolinite, this study found a significant difference in the dissolution rates of kaolinite and diaspore in a low-alkali solution. This conclusion was drawn through a combination of kinetic analysis and experimental exploration. Therefore, a new chemical pre desilication method of diaspore bauxite rich in kaolinite was proposed. The experiment found that at temperature of 180 ℃ and Na2O concentration of 20 g/L, the solubility of kaolinite in a low alkali solution was 3.3 g/L. After 40 minutes of reaction, the maximum dissolution of kaolinite reached 4.2 g/L. Under the same conditions, the solubility of diaspore was 0.064 g/L. The results of kinetic study showed that the activation energy of pure kaolinite dissolution reaction was 26.77 kJ/mol, which belongs to diffusion control. Conversely, the dissolution reaction activation energy of pure diaspore was 84.30 kJ/mol, which belongs to chemical reaction control. In low alkali systems, there was a significant difference in dissolution rate between the two. By optimizing the process conditions, the optimal process conditions were found. Under the optimal conditions, the aluminum silicon ratio increased from 3.22, 2.91, and 2.68–7.92, 8.42, and 8.17, respectively, by processing three types of low-grade bauxite with different particle sizes. It is noteworthy that this method can achieve a significant increase in bauxite A/S only requiring two simple processing steps: alkali dissolution and liquid-solid separation. This study not only fills the research and application gap of low alkali solutions in the field of bauxite beneficiation, but also helps to support the green and sustainable development of the world's alumina industry.
