A Study on Song Dynasty’s Documentary Collection on Tea Ceremony Affairs and Major Documents on Tea
Authors:   Association for International Tea Culture, You Su-hyeon
Published: July 2023

This study examined the major contents of some 70 kinds of tea rites and eight kinds of tea books from Song Dynasty based on A Collection of Chinese Historical Materials on Tea Leaves (中國茶葉歷史資料選集) compiled by Jin Jo Gyu and Ju Ja Jin. In China, the writing of books on tea started with Tea Classic(茶經) by Yuku in Tang. In Song Dynasty, a hefty 30% of Chinese ancient books on tea were published, including Cheonmyeongrok by Dogok, Darok by Chaeyang, Yongcharokhuseo by Gu Yang Su, Pumchayorok by Hwang Yu, Donggyesidarok by Song Ja An, Daegwandaron by Emperor Huizong Zhao Ji, SeonhwaBukwonGongChaRok written by Woongbeon(熊蕃), and Bukwonbyeolrok by Jo Yeo Ryeo. In Song, some 70 kinds of tea rites were further enriched by literati s literary talent and emotion such as the writing of poems or literary commentaries. In those times in Song, many literati, scholars, and government officials were the very masters of teas, and they created the harmonious beauty and deep mental world into poems, calligraphies and paintings, from their tea life.
In particular, most of books on tea published in Dynasty feature many contents of tribute tea. Nearly all authors of tea books were government officials in charge of tea rites in Bukwon, including officials responsible for transporting grains as taxes in Bukwon, Geonan. The books recorded the authors first-hand experience, detailing the entire process of making tea from cultivation to collection to drying, as well as kinds of tribute tea. Books on tea published in Song are important historical materials for researching Song s tea industry and tea culture. Song s tea culture reached the loftiest level in the history of China. Considering the times publication circumstances and expansive geographical scope, however, the distribution of books on tea and exchange of knowledge presumably were not facilitated. Due to such circumstances, Song s books on tea were generally written based on compilers experience, observation and knowledge.

Authors: Fang Qiansheng , Zhao Hongyu , Xie Chenlei , Chen Tao
Published: July 2023

Recently, the scale and complexity of water distribution networks (WDNs) have been increasing with the acceleration of urbanization process. It has become a hot research focus to use district metering area (DMA) for more efficient management and control of WDNs. This article proposes a multistage DMA planning method based on improved weighted spectral clustering and genetic algorithm, aiming to address issues such as high investment cost and large differences in the water network demand distribution. First, the actual case pipe network is transformed into an undirected weighted graph based on graph theory, and a similarity matrix is formed by combining the physical properties and hydraulic characteristics of the water network. Then, based on the similarity matrix, the weighted spectral clustering algorithm is used to preliminarily divide the WDN, and the performance of the water supply pipe network formed with different division quantities and different weighting schemes is discussed. Finally, the genetic algorithm is used to optimize the arrangement of valves and flow meters on boundary pipes to generate the final configuration of DMA. The results show that the proposed method has a significant improvement in pipe network topology, hydraulic performance index, and economy compared with the traditional DMA method.
Learners' perception and needs for the national common basic curriculum
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Bae Sung Ah , An Jung-Hee
Published: July 2023

The purpose of this study is to investigate perception and needs of the secondary school learners' for the national common basic curriculum in terms of individual preference, personal importance and institutional emphasis. The participants in the survey consist of a total of 981 students (487 from 6th grade out of 5 elementary schools and 494 from 9th grade out of 5 middle schools) who completed a questionnaire-based survey. Survey results reveal that difference in the students' preference between subjects is statistically meaningful. It is also observed that, as students's grade get higher, they further lose interest in subjects, and the levels of personal importance and institutional emphasis turn out to be high for the core subjects (e.g. math, english, science) regardless of their grade. These results indicate that, although the students are more interested in non-core subjects (e.g. music, art, physical education, etc), the core subjects with high emphasis, meaning that the students think schools put more emphasis on the core subjects than other subjects, are also recognized as important subjects that they should more focus on. Furthermore, the students show their needs for other subjects (although not specified) besides the current subjects. The findings suggest that more diverse discussion and subsequent realistic activities for listening to and reflecting the learners' opinions in the process of developing and practicing national curriculum are further needed to increase positive effects of the national common basic curriculum on students' learning and achievement.
Proposals for the Right Education of Korean Honorific Forms
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Yang Young-hee
Published: July 2023

This study started from the current situation that students could not accept 'honorific forms' in  textbooks. For analyzing these reasons and making alternatives, questionnaires were made up to the high school and college students in GwangjuㆍJeonnam area.
The term of honorific in Grammar is defined as 'a linguistic method/system to distinguish the level of the targeted person in dialogue both higher and lower'. But most students thought the term 'honorific' as 'the system of expressing speaker's respect to the higher-level person', not to the lower-level. For this reason, this article suggests 'treatment' system as an alternative.
Current Grammar indicates the targeted person in three ways, 'subjectㆍobjectㆍhearer', but the system does not make agreement with learners. Treatment system is a grammatical process that consists of speaker and hearer. The existing terms, object and subject, are the same meaning of grammatical terms of subject, object and adverb. This is very confusing situation and it is difficult for learners to use these terms in real conversation so this article suggests 'person of topic' which means each person as 'subject' and 'object'.
In the current Grammar, when treating hearer, formality form has four level of styles, 'hashipsioh-haoh-hage-hara', and informality form has two level of styles, haeyo-hae'. But learners almost do not use 'haoh' style so this is eliminated from the level in this study. In addition, when dividing the level of treating hearer, [±respect] should be the base of the level, not [±formality].

Benford's law as mass movement detector in seismic signals
Authors: Zhou Qi , Tang Hui , Turowski Jens Martin , Braun Jean , Dietze Michael , Walter Fabian , Yang Ci-Jian , Lagarde Sophie
Published: July 2023

Seismic instruments placed outside of spatially extensive hazard zones
can be used to rapidly sense a range of mass movements. However, it
remains challenging to automatically detect specific events of interest.
Benford’s law, which states that first non-zero-digit of given datasets
follow a specific probability distribution, can provide a
computationally cheap approach to identifying anomalies in large
datasets and potentially be used for event detection. Here, we select
raw seismic signals to derive the first-digit distribution. The seismic
signals generated by debris flows, landslides, lahars, and
glacier-lake-outburst floods follow Benford’s law, while those generated
by ambient noise, rockfalls, and bedload transports do not. Focusing on
debris flows, our Benford’s-law-based detector is comparable to an
existing random forest method for the Illgraben, Switzerland, but
requires only single station data and three non-dimensional parameters.
We suggest this computationally cheap, novel technique offers an
alternative for event recognition and potentially for real-time
warnings.
A Road Map for Peer Review of Real-World Evidence Studies on Safety and Effectiveness of Treatments

Published: July 2023

The growing acceptance of real-world evidence (RWE) in clinical and regulatory decision-making, coupled with increasing availability of health care data and advances in automated analytic approaches, has contributed to a marked expansion of RWE studies of diabetes and other diseases. However, a recent spate of high-profile retractions highlights the need for improvements in the conduct of RWE research as well as in the associated peer review and editorial processes. We review best pharmacoepidemiologic practices and common pitfalls regarding design, measurement, analysis, data validity, appropriateness, and generalizability of RWE studies. To enhance RWE study assessments, we propose that journal editors require 1) study authors to complete RECORD-PE, a reporting guideline for pharmacoepidemiological studies on routinely collected data, 2) availability of predetermined study protocols and analysis plans, 3) inclusion of pharmacoepidemiologists on the peer review team, and 4) provision of detail on data provenance, characterization, and custodianship to facilitate assessment of the data source. We recognize that none of these steps guarantees a high-quality research study. Collectively, however, they permit an informed assessment of whether the study was adequately designed and conducted and whether the data source used was fit for purpose.

The integration of technologies such as continuous glucose monitors, insulin pumps, and smart pens into diabetes management has the potential to support the transformation of health care services that provide a higher quality of diabetes care, lower costs and administrative burdens, and greater empowerment for people with diabetes and their caregivers. Among people with diabetes, older adults are a distinct subpopulation in terms of their clinical heterogeneity, care priorities, and technology integration. The scientific evidence and clinical experience with these technologies among older adults are growing but are still modest. In this review, we describe the current knowledge regarding the impact of technology in older adults with diabetes, identify major barriers to the use of existing and emerging technologies, describe areas of care that could be optimized by technology, and identify areas for future research to fulfill the potential promise of evidence-based technology integrated into care for this important population.

Published: July 2023

BACKGROUND

Numerous laboratory tests are used in the diagnosis and management of patients with diabetes mellitus. The quality of the scientific evidence supporting the use of these assays varies substantially. An expert committee compiled evidence-based recommendations for laboratory analysis in patients with diabetes. The overall quality of the evidence and the strength of the recommendations were evaluated. The draft consensus recommendations were evaluated by invited reviewers and presented for public comment. Suggestions were incorporated as deemed appropriate by the authors (see Acknowledgments in the full version of the guideline). The guidelines were reviewed by the Evidence Based Laboratory Medicine Committee and the Board of Directors of the American Association for Clinical Chemistry and by the Professional Practice Committee of the American Diabetes Association.

CONTENT

Diabetes can be diagnosed by demonstrating increased concentrations of glucose in venous plasma or increased hemoglobin A1c (HbA1c) in the blood. Glycemic control is monitored by the patients measuring their own blood glucose with meters and/or with continuous interstitial glucose monitoring devices and also by laboratory analysis of HbA1c. The potential roles of noninvasive glucose monitoring; genetic testing; and measurement of ketones, autoantibodies, urine albumin, insulin, proinsulin, and C-peptide are addressed.

The guidelines provide specific recommendations based on published data or derived from expert consensus. Several analytes are found to have minimal clinical value at the present time, and measurement of them is not recommended.

Authors: Han Boyuan , Chen Ziang , Feng Jun , Liu Yuzhu
Published: July 2023

Precious and half-precious metals are widely used in various fields, which makes it of great significance to recycle them, and copper was taken as an example for the investigation in this paper. A system based on laser-induced breakdown spectroscopy combined with machine learning algorithms was developed and employed in the lab to identify and classify several metal devices that contain copper element. According to the obtained emission spectra, 36 characteristic spectral lines of copper element are observed in the spectrogram of high-purity copper, as well as some metallic elements including Zn, Ca, Mg, and Na that also appeared. Moreover, eight types of similar metal devices containing copper element which are common in life (electrode, copper plug, copper tape, carbon brush, wire, circuit board, gasket, and coil) were selected to perform spectral analysis. Rough classification can be achieved by observing the spectra of eight metal devices. The effective classification process of metal devices was implemented by conducting principal component analysis, which built a model to reduce the dimension of spectral data for classification. Several samples are distributed at different positions in the principal component space, which is established based on the three principal components as the coordinate axis. K-nearest neighbors were employed to verify the classification effectiveness, acquiring the final classification accuracy of 99%. The results show that the development system has a broad development prospect for identifying metal copper and classifying metal devices that contain copper element.

Published: July 2023

Data from the Badan Penyelenggara Jaminan Sosial (BPJS) Ketenagakerjaan Indonesia from 2019 to 2021 shows that the number of work accident victims who claimed Work Accident Insurance (Jaminan Kecelakaan Kerja / JKK) continues to increase. The high number of work accidents is mostly caused by unsafe behavior at work sites, one of which is in terms of compliance with the use of Personal Protective Equipment (PPE). One tool that is considered important as a step in reducing work accidents is an identification system for compliance of personal protective safety equipment use that can detect PPE used by visitors or workers. This study develops an automatic identification system that is built using the Convolutional Neural Network (CNN) to identify the use of PPE in the manufacturing technology laboratory. The CNN models used are the 4th and 5th versions of You Only Look Once (YOLO) which are then compared based on two methods: train from scratch and transfer learning. The dataset used for building the detection system has 11,579 images consisting of six classes of PPE objects. Overall performance of the proposed models shows very good results. Moreover, the comparison result among the three models shows that YOLOv5 transfer learning has the best performance with the best precision (94.2 %), recall (91.8 %), and mAP (88.6%).

Published: July 2023

Com o objetivo de analisar as concepções e abordagens pedagógicas da educação ambiental (EA), foi realizada uma revisão sistemática nos artigos da Revista Brasileira de Estudos Pedagógicos (RBEP) entre os anos de 2010 e 2020. A revisão apresenta 11 artigos, analisados com base na operacionalização de Minayo (1999). As categorias a priori se constituem em concepções tradicionais e inovadoras de EA, utilizando como critério de classificação os indicadores elaborados mediante o cruzamento das abordagens do ensino de Mizukami (1986), dos paradigmas educacionais de Behrens (2013) e das correntes de EA de Sauvé (2005). Os resultados demonstram o predomínio da concepção inovadora, sobretudo pelo fato de a maioria dos trabalhos ter sido publicada após o ano de 2015. A diferença temporal é outro fator a considerar: apenas um trabalho incluído na categoria das concepções tradicionais foi publicado nos últimos cinco anos. Acredita-se que os resultados possam contribuir para a ampliação do debate quanto à importante relação entre a abordagem pedagógica e as características da EA na prática docente.

Tracking errors severely impact the effectiveness of augmented reality display techniques for indoor navigation. In this work we take a look at the sources of error and accuracy of existing tracking technologies. We derive important design criteria for robust display techniques and present objective criteria. These serve evaluation of indoor navigation techniques without or in preparation of quantitative user studies. Based on these criteria we propose a new error tolerant display technique called Bending Words, where words move along the navigation path guiding the user. Bending Words outranks the other evaluated display techniques in many of the tested criteria and provides a robust, error-tolerant alternative to established augmented reality indoor navigation display techniques.

Upper Albian, Cenomanian and Lower Turonian stratigraphy, ammonite and inoceramid bivalve faunas from the Cauvery Basin, Tamil Nadu, South India
Authors: Gale Andrew S. , Kennedy William J. , Walaszczyk Ireneusz
Published: July 2023

The lithostratigraphy, biostratigraphy, sequence stratigraphy, ammonite and inoceramid faunas of the Upper Albian, Cenomanian, and Lower Turonian Karai Formation, the highest unit of the Uttatur Group in the Pondicherry Sub-Basin of the Cauvery Basin in Tamil Nadu, south India, are documented. Detailed logs and descriptions of sections between Karai and Kulakkalnattam, Odiyam and Kunnam, and north-west of Garudamangalam are presented. They provide the evidence for an ammonite zonal scheme that can be correlated in detail with sequences developed in Europe, with successive Upper Albian zones of Pervinquieria (Subschloenbachia) rostrata and P. (S.) perinflata (the latter on slight evidence), Cenomanian zones of Mantelliceras mantelli, Cunningtoniceras cunningtoni, Calycoceras (Newboldiceras) asiaticum, Pseudo calycoceras harpax, Euomphaloceras septemseriatum and Pseudspidoceras footeanum. The Lower Turonian is represented by a Neoptychites cephalotus–Mytiloides borkari fauna. Over 120 ammonite species are described, of which Puzosia (Bhimaites) falx, Protacanthoceras parva, Watinoceras elegans, Euomphaloceras varicostatum, Kamerunoceras multinodosum, and Carthaginites multituberculatus are new. The new genus Kunnamiceras, with Ammonites tropicus Kossmat, 1865 as type species, is interpreted as a paedomorphic dwarf derivative of Pseudocalycoceras harpax (Stoliczka, 1864). Ammonite faunas from shales are dominated by feebly-ornamented taxa: leiostraca; those from sandstones by strongly ornamented taxa: trachyostraca, differences interpreted as reflecting the preferred habits of adults in life. 15 species of inoceramid bivalves, including a newly described species Inoceramus chiplonkari, are recognised, with a mixed East African–Euramerican–North Pacific affinity. On the basis of the stratigraphic framework developed, a sequence stratigraphic interpretation of the Karai Formation is proposed, and correlated with those recognised in Europe, Morocco, and the United States Gulf Coast and Western Interior.

Published: July 2023

This paper aims to show the relationship between environmental, social, and governance (ESG) factors and the most common supply chain (SC) performance indicators within an organization. The main interest is to identify the challenges that organizations face when trying to gain a competitive advantage over other organizations by measuring supply chain efficiency and effectiveness. Therefore, the concepts and terms used are clarified in the first section, in a broader framework, to note their relevance in the context of the paper, but also the relationship between them. In the second section, scientific papers on this topic are briefly presented, which served as a scientific foundation and prompted us to undertake our study to contribute to the body of scientific knowledge on this little-addressed topic. In the third section of the research, we established a qualitative design, composed of qualitative data from secondary sources, which were obtained data through a literature review and analysed using the comparative-deductive method. The result is to propose a simplified model for measuring SC performance from an ESG perspective. In the conclusions, possible uses of this model are proposed, as well as future perspectives that could improve performance measurement by adding new indicators.
Manifestations of Gender Inequality on the Labour Market: Wage Gap Specificities
Authors: Florişteanu Elena
Published: July 2023

Even though data from the last few years on gender disparities on the labour market show significant improvements, a large number of gender-based differentiation practices can still be observed. Most of the differences noticed are not only reflected in the quality of working women’s social and working lives, but also in quality of their life after retirement. The results achieved by applying the principles of good practice in equal opportunities and treatment between men and women on the labour market can translate into benefits not only for women but also for the society and the economy as a whole. The paper examines some of the typical occurrences of gender inequality in employment relations, with specific focus on the pay gap. In order to obtain the most relevant results, databases of several recognized institutions are used for documentation and analysis, as well as the results of previous research, reports, and studies published at national and international level. I believe that a multidimensional and unified approach to this kind of problem is still needed, as the potential results can stimulate further action in this field.

PURPOSE. The article examines the problem of assessing fire hazard in tank farms in Russia when storing gasoline in steel vertical tanks (SVT). The greatest danger is represented by emissions of oil product vapors from the respiratory systems of tanks of SVT type, which leads to the formation of explosive concentrations zones. To assess the possibility of an explosive concentration formation in the gas space of a tank, it is necessary to know the value of the saturated vapor pressure at different temperatures. Data on the fire and explosion properties of the new brands of gasoline, which are stored in tank farms in Russia, in particular, on the saturated vapors pressure, are not available in the reference literature. This fact makes it difficult to provide an impartial quantitative assessment of the fire and explosion hazard of SVT and tank farms in general. The article substantiates the assessment of fire danger mainly using experimental data. METHODS. In the course of the study, analytical and experimental methods to determine the motor gasoline saturated vapor pressure were used. FINDINGS. Using the experimentally obtained pressure of saturated vapor of AI-95-K5 gasoline (рн = 64.97 kPa), the sizes of the explosive concentrations zones formed in the open space in the vicinity of SVT pressure vent valves with a capacity of 1 000 m3 to 50 000 m3 were determined. The analysis of data on the pressure of motor gasoline saturated vapor obtained both analytically and experimentally was carried out, as a result discrepancies in its numerical value by 20% were revealed. RESEARCH APPLICATION FIELD. Conducting experimental research will update the numerical value of the saturated vapor pressure of currently implemented liquid motor fuel brands. CONCLUSIONS. The experimental method is more expensive and time consuming than the analytical one, but it allows obtaining more reliable values of the gasoline saturated vapor pressure, which in turn directly affects the size of explosive concentration zones at industrial facilities.
Engineering methodology for operational degrees forecasting residential buildings destruction under the influence of conventional destruction means
Authors:   State Fire Academy of EMERCOM of Russia, Sednev Vladimir A. , Koshevaya Elena I. ,   State Fire Academy of EMERCOM of Russia
Published: July 2023

PURPOSE. In the works previously performed by the authors it has been proposed to determine conditions for buildings destruction by the method of the stress state automated calculating their building structures after external loads redistribution as a result of “destroyed” elements removal from the design scheme. This has made it possible to determine for the first time the types and number of the buildings supporting structures elements, whose destruction leads to their collapse. In addition, the degree of building destruction is determined not by the amount of overpressure in the front of the air shock wave acting on the building, but by the amount of economic damage, based on the feasibility of its restoration, depending on the proportion of destroyed interconnected structural elements of the building. For the first time, it allows promptly predicting both the degree of individual buildings destruction and their groups in the lesion focus. METHODS. The authors have used positions of the probability theory and the apparatus of mathematical statistics, as well as methods for determining the overpressure in the front of the air shock wave under the influence of conventional destruction means. FINDINGS. As a criterion for the effectiveness of the proposed methodology for forecasting the degree of buildings destruction under the influence of conventional destruction means, the accuracy increase degree of buildings destruction level determining has been taken. A comparative calculation of the brick building destruction degree has been made. With regard to panel and monolithic buildings, it is impossible to perform comparative calculations, due to lack of data on the magnitude of overpressure in the front of the nuclear explosion air shock wave, which causes weak, medium, strong and complete destruction of residential buildings of these types. RESEARCH APPLICATION FIELD. The results can be used to forecast the volume of emergency recovery work in relation to residential buildings and areas of cities and economic facilities under the influence of conventional destruction means as well as to develop measures to ensure the stability of residential buildings functioning as a result of conventional destruction means impact. CONCLUSIONS. Scientific and methodological approaches for the operational forecasting the residential buildings destruction degree under the influence of conventional destruction means are proposed. The analysis of comparative calculations shows that the accuracy of the developed methodology application in comparison with the existing ones is increased by 50 %.

Published: July 2023

The paper discusses the influence of bentonite saturation, package failure and water conductive fracture network on the transport of long-lived low sorbing radionuclides in geological disposal facilities (DGR). Based on the example of 129I, the study evaluates the influence of space and time dispersion of radionuclide transport and processes mentioned above on the long-term DGR safety. It demonstrates that these effects can cause significant radionuclide retention, nevertheless having minor impact on the long-term DGR safety as regards low sorbing nuclides with their half-lives amounting to over hundreds of thousand years. The paper also considers the opportunities for enhancing the GDF safety considering such radionuclides.

This article describes the development of a sustainable project to requalify the Residencial Araguaia square located in the city of Santana do Araguaia/PA. The requalification of the square was designed based on a demand from the residents' association of the Residencial Araguaia housing complex. The definition of the needs program was carried out by means of a meeting with the residents, for the delimitation of uses, collective and community, so that the urban equipment could meet their real demands. The multidisciplinary team sought a proposal to meet these needs, considering local materials, cultural/environmental aspects, as well as their humanized social impact for the municipality. The result was a sustainable project with the requalification of the square with an area of 7,557.00 m², consisting of a bike rack, bus stops, bike path, walking track, sports court, community center, gourmet space, playground, sidewalks, parking and pergolas. Therefore, the proposal sought to listen to the population directly affected by the problem of precariousness of urban equipment, to better understand the real need, as well as expectations, for the development and completion of the project that was made available to the community

Since ancient times, Indonesia has always been rich in agricultural products such as rice, soybeans, corn, peanuts, cassava, and sweet potatoes. In addition, there are also products from agriculture that are referred to as trade crop agricultural products, namely tea, coffee, coconut, quinine, cloves, sugar cane, rubber, and others. The agricultural sector in 2021 will grow by 1.84% and contribute 13.28% to the national economy. Then in 2022, the agricultural sector will show consistency with a positive growth of 1.37% and contribute 12.98% to the national economy. Then it is necessary to group the productivity of agricultural products using the k-means clustering method to group data on the highest and lowest yield types according to the District in Bojonegoro so that the types of agricultural products that are most productive and less productive can be identified. The method used in this study is K-Means cluster analysis by first determining the number of groups to be formed. In this study, the data used is secondary data on agricultural products originating from One Bojonegoro Data. The food crops in question are rice, shallots, soybeans, large chilies, corn, and so on. From the results of grouping agricultural products based on the year of production, the best types of crops will be known, and which districts will produce the most productive food crops so that the distribution of food crops in Bojonegoro District can be controlled. Productivity grouping of agricultural products can be used as a strategy to increase agricultural yields

This research studied the spatiotemporal changes in land use (LU)/land cover (LC) in Dambatta local government area, with a view to identifying the effect arising from the observable changes in land use patterns. The imageries used in the study were obtained from the National Space Research and Development Agency (NARSDA), Abuja. Spatial analytical techniques and descriptive statistical techniques were employed to analyze the data. The results showed 66.8% reduction in agricultural lands, 45.5% reduction in vegetation cover, 223.2% increase in built-up areas, 269.1% increase in bare lands and 70% increase in water bodies within the 20 years. Spatio-temporal analysis of the three imageries revealed that agricultural lands were largely been taken over by urbanization while vegetation had rapidly given way to bare lands within the 20 years. It was observed that these changes resulted from anthropogenic activities, environmental factors and climate change. These result in the loss of farmlands, inadequate food supply, unemployment, inadequate industrial raw materials, reduction in revenue generated, forest depletion, desertification, wildlife extinction and temperature increase. While it is recommended that reforestation, land reclamation and irrigation agriculture should be promoted in the area, it is also suggested that further research should focus on the impact of climate change on land cover change in the area.
