Criteria That Guide the Professor's Practice to Explain Mathematics at Basic Sciences Courses in Engineering Degrees in Peru. A Case Study

Background : Research on mathematics teaching in basic science classes within Peruvian engineering degrees was required prior to the identification of alternatives to improve the training of future engineers. Objective : To identify the criteria that guide the practice of professors in Peru when explaining mathematics in basic science classes within engineering degrees, with specific reference to derivatives. Design : Qualitative case-study research that seeks to understand current mathematics teaching through an analysis of and reflection on the participants’ practices. Setting and participants : Professors who give classes within engineering faculties in Lima. One of these was selected as a case study. Data collection and analysis : The classes taught by these pr Criteria That Guide the Professor's Practice to Explain Mathematics at Basic Sciences Courses in Engineering Degrees in Peru: A Case Study ofessors were filmed and the criteria they follow in the design and implementation of their classes were inferred by means of the didactic suitability criteria, which were also used to design a questionnaire to interview the teachers; triangulation was then performed between their words and their actions. Results : This professor was guided by ecological criteria (syllabus and profession) and mediational criteria (time available for classes), although he felt that his practice was based primarily on cognitive criteria (previous knowledge) and ecological criteria (future profession). Conclusion : The criteria that guided his practice help explain why basic science classes within engineering degrees are taught with a lecture-based and procedural approach, and why innovations are not included.

Rethinking the campus transportation network in the scope of ecological design principles: case study of Izmir Katip Çelebi University Çiğli Campus.

The concept of sustainability, which has become increasingly important in every aspect of life, has become a topic that is often emphasized for university campuses, which can be considered a small urban model. Many universities in Turkey and abroad are working on sustainable campuses. They set many environmental, social, and economic targets such as reducing the carbon footprint, using green technologies, designing by human and environment oriented principles, using green transportation systems, reducing costs, and eliminating social injustice. In this study, the transportation network of İzmir Katip Çelebi University, Çiğli Campus, which was established on an area of 70 ha in 2010, was examined within the scope of sustainability and ecological design criteria, and a transportation network focused on pedestrian and bicycle was also suggested. This study consists of two stages. In the first stage, the current situation analysis of the campus transportation was presented, and in the second stage, recommendations were made for a sustainable transportation system within the campus, taking into account the ecological design criteria.

Practical Functioning of a Sustainable Urban Complex with a Park—The Case Study of Stavros Niarchos Foundation Cultural Center in Athens

Intensive urban development has created a shortage of urban green areas. The need to economically plan and use urban green spaces has fueled the redefinition of public spaces and parks so as to provide the residents with both recreation and relaxation facilities, as well as a forum for contact with culture. This paper discusses the case of the Stavros Niarchos Foundation Cultural Center (SNFCC) in the Kallithea district on the outskirts of Athens, near the Mediterranean Sea. It fills a gap in the research on the aspects of the practical functioning of such facilities. The methodology used in the research included an analysis of the literature, the SNFCC’s reports, and an in situ survey. The cultural center hosts a number of events aimed at promoting Greece’s natural and cultural heritage. The paper includes a detailed analysis of the events organized by the SNFCC in the period 2017–2020 and their immense impact on residents. The aim of the study is to show that the creation of the SNFCC with the park areas has functioned as a factor contributing to the improvement of the quality of urban space and the quality of life of the city’s inhabitants. The paper’s conclusions indicate that the sustainable SNFCC project, which fulfils the urban ecology criteria, has been very well received by the visitors—citizens and tourists alike. A program-centered innovation introduced by the SN Park has added great value to their lives. The project contributes to economic and cultural growth, as well as the protection and promotion of heritage.

Application of Interval Fuzzy Logic in Selecting a Sustainable Supplier on the Example of Agricultural Production

The selection of sustainable suppliers (SSS) is the first step in applying a sustainable supply chain and sustainable production. Therefore, it is necessary to select the supplier that best meets the set sustainability criteria. However, the selection of suppliers cannot be done by applying symmetric information, because the company does not have complete information, so asymmetric information should be used when selecting suppliers. Since the SSS applies three main sustainability criteria, environmental, social, and economic criteria, this decision-making problem is solved by applying multi-criteria decision-making (MCDM). In order to solve the SSS for the needs of agricultural production, interval fuzzy logic was applied in this research, and six suppliers with whom agricultural pharmacies in Semberija work were taken into consideration. The application of interval fuzzy logic was performed using the methods PIPRECIA (Pivot pairwise relative criteria importance assessment) and MABAC (Multi-Attributive Border Approximation Area Comparison). Using the PIPRECIA method, the weights of criteria and sub-criteria were determined. Results of this method showed that the most significant are economic criteria, followed by the social criteria. The ecological criteria are the least important. The supplier ranking was performed using the MABAC method. The results showed that supplier A4 best meets the sustainability criteria, while supplier A6 is the worst. These results were confirmed using other MCDM methods, followed by the sensitivity analysis. According to the attained results, agricultural producers from Semberija should buy the most products from suppliers A4, in order to better apply sustainability in production. This paper showed how to decision make when there is asymmetric information about suppliers.

Bioleaching and ecological toxicity assessment of carbide slag waste using Acidithiobacillus bacteria

Abstract Carbide slag generated from industrial sites can contain many organic and inorganic impurities such as toxic metals and organic compounds, which should be treated before disposal. Bioleaching using Acidithiobacillus ferrooxidans, Acidithiobacillus thiooxidans and their combination was investigated. The effects of important factors including pH and pulp density were assessed. It was found that under optimal conditions 100% Zn, 41.9% Ba, 98.5% Ni and 97.8% Li were extracted with the mixed culture of Acidithiobacillus at pH 1 with pulp density 0.5% (w/v) after 14 days. To ensure risk reduction of the carbide waste for the soil environment, ecological risk criteria and plant seed germination potentials were evaluated. The results showed that bioleaching significantly reduced slag toxicity, and plant seed germination from leached waste was observed.

Ecological criteria for designing effective MPA networks for large migratory pelagics: Assessing the consistency between IUCN best practices and scholarly literature

Networks of Marine Protected Areas (MPAs) have been proposed as one tool for the protection of large, migratory pelagic species, but debate exists on the utility of MPAs for these species. International conservation arenas have developed criteria for effective MPA networks, with the IUCN-WCPA [1] outlining five ecological guidelines in designing resilient MPA networks. This review examines recent literature to: (1) assess the degree to which the five IUCN guidelines address large migratory at-risk pelagic species; (2) assess differences between the scientific literature and IUCN guidelines in the manner in which effective MPA networks are conceptualized for these species; (3) identify additional relevant design themes for effective conservation of migratory pelagics through MPA networks not addressed by the IUCN guidelines; and, (4) identify challenges and opportunities for the design of MPA networks for this suite of species. Results indicate that neither the literature nor the IUCN-WCPA guidelines provide comprehensive strategies for designing MPA networks for large, migratory pelagic species. The study concludes that the IUCN-WCPA guidelines can be potentially effective for these species if migratory connectivity is fully accounted for and complementary adaptive and dynamic mechanisms are developed for integration across wider seascapes and sectors at large regional and global scales. To this end, updates to the design guidelines for MPA networks are warranted, particularly with respect to connectivity, adaptive and dynamic approaches, and international collaborations. Greater clarity and consistency in the definitions and uses of the terms MPAs and MPA networks is warranted to facilitate collaborative efforts.

Emerging mercury mitigation solutions for artisanal small-scale gold mining communities evaluated through a multicriteria decision analysis approach

Over 15 million people are involved in artisanal small-scale gold mining (ASGM) globally. Often, ASGM includes smelters that use mercury to extract gold. If mishandled, these actions may cause adverse health effects for smelters and their surrounding communities. There are multiple tools to reduce health risks while maintaining a sustainable economic profit, but each method has trade-offs, such as cost, efficiency, and potential health impacts that are not widely understood. Multicriteria decision analysis (MCDA) is a powerful tool in assessing multiple perspectives and factors that affect stakeholder decisions and can be used to inform smelters and community members on reducing exposure to mercury. Here, MCDA was used to determine the ranks of alternatives to reduce exposure to mercury based on socio-economic, ecological, and human health criteria. Stochastic processes were used to evaluate 12 alternatives, including mitigation strategies (i.e., chelation therapy techniques, retorts, water filters) as well as mercury-free mining substitutes. In this model, the borax method ranked first 72% of the time, followed by the gravity method (19%), a multicapture system retort (7%), and low-cost retorts (≤ 1%). While MCDA is an excellent tool, results tend to be generalized across a heterogenous landscape. More localized factors such as incorrect soil chemistry could cause performance challenges for options like mercury-free mining substitutes. To aid more localized decision-making, a decision tree model was developed to aid stakeholders to explore which alternatives are suitable based on context-specific factors using “Take-the-best” decision heuristics. This work can assist researchers and stakeholders involved with ASGM to identify which options are scalable for their region as well as to mitigate adverse effects of exposure to mercury.

Multi-criteria of PV solar site selection problem using GIS-intuitionistic fuzzy based approach in Erzurum province/Turkey

Renewable energy sources have been placed as the key to facilitating to provide source of electricity generation. Solar power is one of the most preferable one among renewable energy sources due to the easy to generate in suitable environment. However, there are concerns with the location of solar power plants installation which causes low efficiency and ineffective use. Hence, determining the location for the usage of solar power sources is critical to mitigating those concerns. In addition, Turkey has been focused on investments on sustainable renewable energy sources and there are few studies which work on cities to reveal potential sources. In this study, GIS and intuitionistic fuzzy set based multi-criteria decision-making method is proposed for determining the most suitable areas for solar energy power plant potential site selection in Erzurum province, Turkey. Firstly, a solar energy power plant potential site selection map is made using a GIS program along with considering ecological risks and ecological criteria. Secondly, 20 districts of Erzurum are investigated in terms of 10 criteria (slope, aspect, solar irradiation, land use, wind speed, air temperature, air pressure, air humidity, land surface temperature and transmission line) using intuitionistic fuzzy sets. In these parameters the first time we looked the land use surface. The land use surface is affected the efficiency of the solar power plant. Finally, the comparisons of two methods are done to check consistency of results obtained. The results indicate that both approaches achieve same areas as the most suitable locations for solar power plants installations for Erzurum province in Turkey. The aim of this work is first to investigate possible locations for solar power plant installation using a mapping method, GIS, and then, Intuitionistic Fuzzy is applied to the problem to obtain optimum areas for solar energy. Also, more accurate results are provided comparing results of two methods, GIS and Intuitionistic Fuzzy. The results expose that 25,065.3 km2 for solar power plant suitable for solar power plan installation.

Technique of Assessment of Environmental Damage Caused by Electroplating Production Facilities (by the Example of Chromium Plating Process Lines)

The use of galvanic chromium plating is accompanied by negative consequences related to considerable damage caused to the environment. The authors have developed new chromium plating electrolytes and methods to obtain chromium-based galvanic alloys which allow reducing the environmental harm and decreasing the morbidity rate of occupational diseases among operating personnel. A technique of assessment of environmental damage caused by electroplating production facilities, which is based on the ecological compatibility criterion has been suggested.

The Importance of Values in Predicting and Encouraging Environmental Behavior: Reflections From a Costa Rican Small-Scale Fishery

Encouraging people’s pro-environmental behaviors is an objective of Education for Sustainable Development. In the context of small-scale fisheries, unsustainable fishing practices are compromising the integrity of coastal communities and ecosystems. Ecopath with Ecosim (EwE) is an ecosystem modeling software that presents interactions/changes in the food web as a result of fishing. Despite the multiple applications of EwE in fisheries management, it is unknown from a quantitative perspective whether the application of EwE trophic modeling in environmental education processes and management produces effects on norms and ecological beliefs, and if it alters behavioral intentions of the participants receiving ecosystem modeling information. We conducted a behavior change intervention with gillnet fishers in the Gulf of Nicoya, Costa Rica, to compare antecedents of pro-environmental behavior between participants who received an ecosystem-based intervention (lectures containing EwE models; treatment) and those who received lectures that didn’t involve EwE (control). Based on theories of environmental psychology, we used a pre–post survey design, to evaluate changes between control/treatment, and to assess the influence of psychometric constructs and fishing characteristics on the behavioral intentions to support sustainable fishing measures and owning a fishing license (revealed behavior). Personal norms and values were significant at explaining management measures’ support, along with some fishing characteristics (e.g., fishing site). Deliberating about possible future scenarios (via EwE-modeling) helped reduce uncertainties, increasing legitimacy and a perceived behavioral control (PBC) to support measures. Currently, licenses in the Gulf aren’t granted under defined ecological criteria, and although altruistic-biospheric values scored highly before the intervention began, due to mistrust and high illegal-unlicensed fishing, fishers may be underestimating how much others care about the environment. Value-oriented and ecosystem-based interventions may assist to effectively redesign the licensing system and encourage fishers to support sustainable measures. Our research indicates the importance of education interventions that teach about the impacts of fishing in the ecosystem while helping participants to perceive themselves as capable of implementing actions (PBC) and expressing biospheric-altruistic values to restore trust. Redirecting human behaviors to reconnect with ecosystem resilience can be a leverage point for sustainability and for the compliance of small-scale fisheries management measures.

Distribution and environmental risk assessment of trace metals in sludge from multiple sources in Taiwan

ABSTRACT: This study evaluated the level of the contaminant of the heavy metals in sludge from different sources and the ecological risk criteria associated with it was also analyzed to establish its reuse in agriculture. The sludge samples were collected from the water plant (WTP), wastewater treatment plant (WWTP), and industrial water treatment plant (IPT) in Taiwan. The inductively coupled plasma mass spectrometry was used to measure the trace metals in sludge. The pollution level and ecological risk criteria for heavy metals in sludge were also used to evaluate its reuse in agriculture. The result shows the average concentrations of trace metals in sludge for three groups (WTP, WWTP, and ITP). Significant correlations were found between concentrations of Zn-Ag (p < 0.001). The higher values of I geo showed in ITP, indicated Hg to be a major pollutant. In Taiwan, the regulations did not establish the reuse of sludge in agriculture. However, the concentration level of trace metals in sludge was particularly lower than the regular levels in most groups, like WTP and WWTP groups. The industrial sludge was not recommended for the use in agriculture. The results of this study can be used for regular monitoring to establish a reference for sludge management and application to agriculture.

Assessing the performance of gray and green strategies for sustainable urban drainage system development: A multi-criteria decision-making analysis

The performance assessment of a sustainable urban drainage system (SUDS) involves multiple criteria and is important for the decision-making of urban sustainable development. In this study, we intend to balance the comprehensiveness and objectivity in the performance assessment of SUDS development through a combination of multi-criteria decision-making (MCDM) analysis and mathematical quantification. We proposed an MCDM framework with eight quantifiable indicators, including flood mitigation capacity, pollution control capacity from technical criteria, life-cycle cost, damage cost, recreational function from socioeconomic criteria, biotope area ratio from ecological criteria, and spatial consistency from political criteria. A city-scale model based on engineering datasets and satellite images was created to implement gray and green infrastructure strategies in the studied area. Results revealed that gray strategies performed better in hydraulic improvements, mitigating approximately 17% of flood magnitude and decreasing over 20% of flood-induced damage. Green strategies were more eco-friendly, removing approximately 60% of non-point pollution and improving at most 15% of the ecological level. Integrated assessment demonstrated that the combine-used strategy showed the overall best performance, with a sustainability index of 0.676. Therefore, the methods and results in this study could provide additional improvements in the decision-making process of SUDS development.

Distribution, contamination status and bioavailability of trace metals in surface sediments along the southwest coast of India

This study investigates the influence of upwelling induced seasonal hypoxia in the sediment-water interface on the distribution, bioavailability and geochemical partitioning of selected trace metals in surficial sediments along the southwest coast of India based on two successive cruises. The first cruise was during the southwest monsoon (SWM) season when coastal waters exhibited intermittent bottom hypoxia due to upwelling. The second cruise during the northeast monsoon (NEM) season was characterised by a uniformly warm and well-oxygenated water column in the study region. The results showed that grain size, organic carbon and Fe are the major factors influencing the distribution of trace metals in the surface sediments. Based on the geochemical indices (contamination factor, enrichment factor and geo-accumulation factor), the study region appears to be moderately contaminated by Ni, Cr, and Pb. Based on the ecological risk assessment criteria, the enrichment of Pb, Cr and Ni may cause adverse effects on the benthic organisms. The fractionation studies demonstrated that the major pathway of metal deposition in the sediment is lithogenic. The data also showed that labile and organic fractions are the second dominant forms, while other fractions (exchangeable and carbonate) are insignificant. The consistency in the reactive Fe concentrations during SWM and NEM could be due to the absence of Fe dissolution in sediments under mild reducing condition (intermittent hypoxia). In addition to the above, an enrichment of organic matter also leads to increased deposition of trace metals in sediments. Conversely, the secondary phase enrichment factor and risk assessment code calculated based on the metal fractionation data indicated low risk and contamination along the southwest coast of India except for Zn that showed moderate contamination in some transects. The study provides the need for regular geochemical assessment to control metal pollution in the coastal environment, which is a major resource of the fishery.

Developing an USACE method to rehabilitate Hour-al-Azim marsh and dust management

Abstract Hour-al-Azim marsh is one of the most significant wetlands of the Mesopotamia watershed. In the past few years, severe environmental and hydrological stress have caused the loss of a large part of its area and its bed has become the largest focal point of haze in the southwestern of Iran. Determining delineation is one of the most important and necessary measures to protect a wetland's ecosystem and, in this study, delineation was determined using the USACE-R-G method. This method is a combination of ecological and hydrological criteria with a Remote Sensing and Geographical Information System. The results showed that under the first scenario the marsh is about 3,279 km2 which about 882 square kilometers constitute free-water surface and its average depth is 2.4 meters. In the second scenario, these numbers were estimated to be 1,619 km2 with an average depth of 2.7 meters. Moreover, the area of the haze focus is about 1,659 km2. As well as this, under these conditions the amount of water required to submerge the marsh is 7.9 in the first scenario and 4.4 billion cubic meters in the second one.

Green Design in Urban Squares: Ecological Urban Consciousness in Landscape Architecture Education

Due to increase in population density in cities, unplanned urbanization, where built areas proliferate and concrete and impermeable surfaces are predominant, have started to capture cities. While this causes the natural environments and green areas in cities to decrease day by day, it also directly affects the formation of heat islands in the cities, air pollution and the decrease in the quality of life of people. Since landscape architecture is a discipline that deals with the planning, development, protection and design of rural and urban open spaces that can make the future better, teaching students the importance of the ecological city and the criteria of designs for this should be the primary goal in universities. The area, which was determined as an Urban Transformation area by Trabzon Municipality and planned to be designed as Karagöz Square, was studied within the scope of Karadeniz Technical University Landscape Architecture Environmental Design Project 4 in the fall semester of 2019-2020. The lecturer of the course aimed to teach the students the awareness of green design-oriented city square solution in line with ecological city criteria. Within the scope of this study, course data were examined with ecological city criteria.

Adaptive Remanufacturing – Methodology towards an intelligent maintenance strategy for production resources

In the face of aggravated resource scarcity and increasing environmental awareness, the lifecycle extension of capital goods holds significant ecological and economic potentials regarding improved resource efficiency and productivity. The innovative approach of Adaptive Remanufacturing is being developed to raise these potentials. Adaptive Remanufacturing describes a proactive, intelligent maintenance strategy, based on the optimal time and scope of measures under technical, ecological and economic aspects. Within this paper, the methodological core elements of Adaptive Remanufacturing are presented. In the first development stream, the respective capital good is prepared for the application of Adaptive Remanufacturing. Therefore, a specific product structure analysis is conducted based on the functional structure and decomposability. On this basis, the product components are evaluated and prioritized according to their relevance for remanufacturing. Further, a detailed multi-sensory concept including machine interfaces is elaborated considering different wear mechanisms to enable the selection of specific measures based on condition monitoring and predicted machine conditions. To facilitate this selection, measures have been identified within a comprehensive literature research, evaluated and structured in a measure catalog within the second development stream. Measures have been categorized into main and auxiliary measures according to related efforts and benefits. Benefits are evaluated according to wear mechanisms as well as technical, ecological, and economic criteria. Additionally, they are classified into short- and long-term performance enhancements depending on the influence on the wear reserve of a component. Both development streams are linked in a decision model recommending specific measures based on machine condition predictions derived from sensor values.

Ecological state of soils and water resources of the central cities of the urbanized territories of Irkutsk oblast, Buryatia and Mongolia

As the pace of urbanization accelerates, the quality of life in large cities is becoming increasingly determined by the level of preservation of the components of the natural environment. One of the main ecological living-standard criteria is the quality of water resources and soils. The article analyses statistical and published materials on soil and water pollution of the Baikal region. Soils and surface water samples taken in the central cities of urbanized territories (Irkutsk, Ulan-Ude and Ulan-Bator), as well as in adjacent territories were analyzed for the content of macro-and microelements. It was revealed that the most contaminated soils are in the city of Irkutsk due to the presence of a large technogenic load and high sorption capacity of soils. Soil degradation and pollution in the Baikal region has been mapped. The map shows actual pollution and possible potential, taking into account environmental conditions. The highest pollution of surface waters is observed in the Tuul river, downstream of Ulan-Bator due to the high technogenic load and the fact that natural waters of steppe regions initially have high content of chemical elements, and the soils are fine textured, therefore, pollutants can easily migrate through surface and ground waters. A map of surface water quality of the Baikal natural territory has been compiled.

ЕКОЛОГІЧНА ОЦІНКА ЯКОСТІ ПОВЕРХНЕВИХ ВОД ЖИТОМИРСЬКОГО ПОЛІССЯ

The ecological assessment of the quality of surface water of the Dnipro basin (within Zhytomyr region) is carried out. In general, surface water of rivers of teter, rotten, Guiva, forest stone, Irsha, Human, Arpin, Rostavitsa and Kamyanka were investigated. The study was conducted according to systematic observations based on the ecological classification of the quality of surface water and estuates in Ukraine, which includes a set of hydrophysical, hydrochemical, hydrobiological and other indicators reflecting the peculiarities of components of aqueous ecosystems. On the basis of unified ecological criteria, the technique allows you to compare the water quality in separate areas of water objects, in water objects of different regions. The calculation of the ecological assessment of water quality was carried out within three blocks: a block of saline composition (I1), a block of troph-sanitary (ecological-sanitary) indicators (I2) and a block of indicators of specific substances of toxic action (I3). The results are presented in the form of a combined ecological assessment, based on the final conclusions of three blocks and is to calculate the integral ecological index (IE). The results of observations on the qualitative state of surface water in the Tetereva Basin, the right tributaries of the Dnieper “Good”, “clean” water (II class of quality) here are less than half (47%) of all observation points. Such a quality is the water of the rivers of Irsha, Guiva, rotten, varnia, teter. In 6% of cases, “satisfactory”, “contaminated” water of the quality of the quality (3,7 ≤ IE ≤5,4), namely: r. Teters, within the city of Zhytomyr, 200 m above the fall of the River Forest Kamyanka and River Forest Kamenka, within the city of Zhytomyr, 100 m above the fall in Teter. Waters of all other research points occupy an intermediate position between II and III of quality classes and are evaluated as “good”, “clean” and “satisfactory”, “contaminated”. The water of the pools Irpen and dew, represented by the rivers Irpin, Rostavitsa and Kamenka, are characterized by the second class of quality “good”, “clean”. Executed researches allowed to analyze and evaluate the ecological state of the rivers of the rivers of the Zhytomyr region within the Dnipro River basin, which will establish the environmental standards of water quality and to determine the basic areas for improving the state of water resources and substantiate the system of recommendations aimed at improving the environmental state of the basins under study in the boundary of the area.

Conditions of hazardous waste management in Poland in the context of circular economy

Along with the increase of disproportions between the rapidly growing demand for raw and essential materials and limited possibilities of obtaining them, the economy of raw and essential materials becomes the main problem of contemporary and future social and economic politics. One of the important areas of reducing this disproportion is the limitation of intensity of waste generation during production and more consistent management of accumulated waste and waste generated on a daily basis. At the same time it is a major problem of obtaining secondary raw materials and the environment protection. The selection of technology of hazardous waste disposal should take place according to the principle of circular economy. It means that the rational waste management, taking into account both ecological and economic factors, enforces the demand for maximizing the utilization of waste in all possible applications while limiting its negative impact on the environment at the same time. In the article legal acts regulating the management of hazardous waste have been analyzed. Economic and ecological criteria of the selection of technology of disposal of hazardous waste have been analyzed.

STUDY OF THE GREEN COVER FULFILLMENT IN THE TOMB OF SULTAN SURIANSYAH TOURIST AREA ON THE RIVERBANK AREA OF THE KUIN

Sultan Suriansyah tomb tourism area is a multi-role cultural heritage area classified in the religious, social and cultural aspects which is also a tourist attraction, economically it is an area that generates income for the residents because of the presence of tourists. Ecologically it has an important role as part of the city and supporting the Kuin riverbank. Therefore, it is necessary to study related to the fulfillment of green cover near the area to be able to assess the optimal functioning of this area both as a support for river banks and the function of the sustainable city of Banjarmasin. The green coverage was estimated by two methods, survey and Geographic Information System (GIS). The survey is an estimation of the canopy width formed on the condition of the trees. Estimation results show the average width of the canopy is around 5 meters that have not met good ecological criteria. The GIS result is still far from the minimum standard requirement. The difference in deficiency reaches ± 60% deficiency that has not yet reached the minimum green space requirement. A deeper study and revitalization of vegetation are needed for the sustainability of the Sultan Suriansyah tombs tourism area.
