Abstract

This article aims to measure the level of sustainability of heritage cities in Malaysia. A thousand residents of ten selected heritage cities throughout Malaysia were selected as the respondents based on the cluster sampling and simple random methods to complete the questionnaire. A Likert scale on questionnaires 1 to 5 was used to elicit feedback. Five sustainability constructs were used: economic, social, environmental, cultural heritage, and government/community role. The results showed that the items in each study construct achieved an acceptable reliability level, with a Cronbach Alpha value greater than 0.70, and also met the normality test requirements. Descriptive analyses of the frequencies, percentages, and average mean values were used to establish each construct's level of sustainability. The results of the study show that the cities that attracted high scores were Georgetown (3.94), Taiping (4.00), Melaka City (3.76), and Muar (3.71). Meanwhile, the cities that attracted moderate scores were Kuala Kubu Bharu (3.36), Jugra (3.23), Tampin (3.37), Kuala Lipis (3.28), Kota Bharu (3.65) and Kuching (3.51). The implications of this study can be used to indicate the actual situation of the level of sustainability of heritage cities and be a reference to carry out the process of improvement towards a more sustainable city by 2030.

Abstract

Farmers in tropical rural areas are confronted with several challenges but outstandingly climate change which can only be overcome by adopting to climate change resilience strategies. This study assessed the factors affecting adoption of climate change resilience strategies in Muyembe sub-county, Bulambuli district, Uganda. We used questionnaires, interviews, focused group discussions and field observations to collect the required data, which was analyzed using basic descriptive statistics and logistic regression model. Results indicate that, the dominant climate change resilience strategies adopted in the study were, soil/water conservation (65%), drought resistant crop varieties (59.4%), and irrigation (55.6). Results of the logistic regression indicated that, gender and family size were the most important factors that influenced adoption of climate change resilience strategies with coefficient -0.86 and P0.05, and0.18 and P0.05 respectively. On the other hand, the barriers to adoption of the same by majority farmers were dominated by financial constraints and adulteration of farm inputs at 93.4% and 74% respectively. We concluded that, many farmers are still locked in indigenous practices that have made them vulnerable to climate change effects characterized by low yields, crop failure hence low incomes, poverty and food insecurity. We recommended that, government should support the adaptation strategies to climate change by the smallholder farmers technically by providing both ground and surface water irrigation facilities and financially by providing agricultural loans as well as focusing on promoting awareness and advancing education on climate change to farmers through knowledge and skill sharing platforms such as training, conferences, and seminars.

Abstract

This study focused on establishing the relationship between sugarcane growing and the livelihood of small-scale farmers in Jinja District.  It was guided by three objectives namely: to characterize individual farmers and their farms, establish benefits from sugarcane farming to the farmer’s livelihoods and find out the effect of sugarcane growing on household food security in the area. The study adopted descriptive research design. The target population of this study were sugarcane growing households’ heads and Village Chairpersons of sugarcane out-growers association.  The study employed the purposive and simple random sampling techniques. A sample size of 42 respondents from a population of 362 small-scale farmers.  The methods of data collection included; use of questionnaires, interviewing, focus group discussions and observation.  The study generated both qualitative and quantitative data. The data collected was analysed by computing percentages while qualitative data was analysed by coding and establishing common themes. The study findings revealed that although women are fully involved in sugarcane growing, ownership of farms is dominated by men. The dominant age group among the sugarcane farmers is between 30 to 60 years, with mainly primary education graduates. The average farm size was 3 acres and the larges part of the farm land is devoted to sugarcane growing. There are some positive benefits from sugar growing, though many challenges have been identified. Most smallholder farmers are experiencing food insecurity.  Based on the findings of the study it was recommended that there was need to encourage people owning land less than five acres to practice mixed farming, use scientific methods of farming such as intercropping, crop rotation, use fertilizers to facilitate better yields and crop diversification to improve both on their earnings and food security.

Abstract

The variety of community activities in urban areas and a poor domestic sewage system are thought to affect the water quality of the Bedadung River. The high level of river pollution is caused by the high amount of polluting waste that enters, thus increasing the pollution load. Point source pollutant sources are sources of pollutants originating from certain sources that can be identified directly, such as domestic waste disposal, industrial activities, and others. Organic pollutants from domestic waste that enter the river can reduce the dissolved oxygen concentration in the river which can affect the quality of river water. The quality of water from pollutants can be indicated by knowing the concentration of the oxygen content in the water. To find out, it is necessary to measure the amount of BOD (Biochemical Oxygen Demand). The BOD value can be used as an index number to measure the level of pollutants from waste in a water system. In addition, changes in land use are also the impact of population growth and increased human activity. Land-use changes that ignore the principles of ecosystem sustainability tend to harm the environment, including a decrease in water quality. This study was conducted to determine the potential point source pollution load of Bedadung River in the Urban Area using information about the Bedadung River both spatial data and pollutant water quality (BOD) data. All data is combined and processed using Geographical Information Systems (GIS) technology. The data were analyzed and plotted into a map depicting the distribution of potential point source pollutant loads in the Bedadung River Urban Area Segment. The results of the analysis of land cover pollutant source areas based on the boundary include rice fields of 18.97%, fields of 5.98%, gardens of 12.85%, rivers of 12.25%, and settlements having the largest land area of 49.96% of the total area of the study area. The results of the calculation of the potential point source pollution load showed that the highest potential pollution load value was in the Kaliwates village of 13.966 kg/day, the lowest was in the Antirogo village of 0.004 kg/day and the total point source pollution load was 36.31 kg/day.

Abstract

A study of karst land use and land cover dynamics is critical for managing karst areas, which provide many pivotal services for people. This study aims to study such dynamics, especially in relation to the karst of Gunung Sewu, due to its development as a new emerging sector. Using a mixed methods approach, the study combines spatial data analysis with qualitative analysis. Spatial analysis was performed to examine the dynamic of the land cover derived from 2013 and 2021 Landsat 8 imagery, analyzed with the Google Earth Engine tool, together with analysis of spatial patterns using Global Moran’s I and LISA. The spatial analysis results were complemented by a qualitative analysis of the environmental history and development trends, as an explanatory method. The land cover analysis reveals a conversion from vegetation to agriculture, while the spatial pattern analysis shows that such conversion has mostly taken place in the northern part of the study area of Wonosari Basin. The environmental history of teak forest exploitation and agriculture is key to understanding current land use related to the emerging tourism sector, which is fundamental to the region. To manage the negative impacts, sustainable land use with a firm policy framework urgently needs to be implemented.

Abstract

Landslide dams are less frequent than other landslides, and their very existence is often very-much short-lived, because the temporary dam tends to collapse rapidly. Because of the resulting lack of evidences, there has been less research done on this topic, although the potential catastrophe they can be at the origin of needs assessment. For this purpose, the present contribution aims at differentiating landslides that trigger dams against those that do not inside a group of valleys of the Kii peninsula in Japan, where landslides occurred af-ter the typhoon Talas in 2011. Using topographic map before the event and LiDAR data in its aftermath, the authors have calculated the factor of safety (FS) of different landslides in the same valleys, comparing the da-ta of landslides that created dams against those that did not. The results show that landslides that triggered dams seemed to have a higher FS than those that did not. The authors suggest that it is because larger land-slides are needed and thus appear more stable, but also because at the location where the slopes are stable, the riverbed can incise further instead of growing horizontally, and thus the sediments damming the channel have more chances to block it (as it is narrow) and stop the river from flowing.

Abstract

The phenomenon of urban growth has become an important issue that affects the land use system and land cover in a region for several reasons, such as population growth and the economy. This phenomenon has also become one of the main environmental issues lately because it has devastated urban ecosystems. Ternate Tengah District has the highest population growth rate in Ternate City and has experienced extensive urban development due to several reasons, such as the pace of urbanization, economic growth, and population. Urbanization accelerates the demand to land for living. As a result, there will be gaps or disparities between land needs and available land, a decline in environmental carrying capacity, and potential environmental harm in the future. Spatial modeling of future land covers is needed to provide data on policy-making. GIS and remote sensing methods have been widely introduced, but the most effective one is CA-Markov. This model has been used in various areas worldwide, but its application to predicting land use change in the populous city of a small island under threat of volcanic hazards like Ternate is limited. This study aims to evaluate and forecast the land-use changes brought on by urbanization in Ternate City's Central Ternate District. We used a cellular automata-Markov chain to examine and forecast land cover changes in 2002, 2012, 2022, and 2032. The findings indicate that residential area development will increase along with population expansion and land demand. The results of this study can support the policy-making related to the future arrangement and utilization of space in The Central Ternate District.

Abstract

Efforts have been made to transform traditional farming practices to organic method in order to ensure sustainable production and environmental conservation. Studying the differences between these two practices through mapping provide insight into the effectiveness of the transformation, as soil characteristics varies in space. Therefore, this study examined the spatial variability of Total Nitrogen, pH, and Organic Carbon in Lombok Kulon village, Wonosari Sub-district, Bondowoso district. The method used consists of: (a) data collection; (b) data input in GIS; (c) processing data, (d) analysis and (e) presentation of results. The results showed that soil organic content in the area was generally low. Furthermore, indicators such as pH, Organic Carbon and Total Nitrogen do not present significant differences between organic and Inorganic practices. The use of Kriging in GIS environment to analyze spatial variability showed variations and inform management decisions relevant to Total Nitrogen, pH and Organic Carbon.

Abstract

This study is based on solid waste recycling activities in Minna, Nigeria. This study examines the potential for waste recycling to provide livelihood opportunities in Nigeria. The study identified two recycling centres in Minna and collected data through direct observation, measurements, questionnaire administration, and interviews. The collected data was analyzed using statistical packages for social sciences and livelihood approach to demonstrate the green value of recycling, identify impediments to green growth, and map the recycling cluster. The result shows that the recycling cluster occupies an area of 0.64 hectares that accommodates 141 recycling outlets, with about 40% of the outlets occupying below the standard shop size of 7.2m2. The recycling outlets use 18 types of recovered materials to reproduce 27 varieties of products. Each recycling outlet engages about 3.4 persons and offers training to an average of 6 persons each. The study highlights the importance and potential of informal solid waste recycling as a sub-sector that fulfils social, economic, and environmental benefits associated with sustainable development. However, the lack of commitment by governments to waste recycling undermines the contribution of the recycling business. Moving towards the zero-waste policy can save public funds that can be invested in the waste disposal and reduce the threat to public health from solid waste. Furthermore, safety measures should be ensured among the scavengers and the recyclers, and the physical environment of the recycling cluster should be upgraded to take care of poor accessibility and the use of makeshift structures by most of the recycling units. Governments should focus on policies that encourage waste sorting, collection, sales, and solid waste processing at all scales. We underscore the need for creative and reliable government support to achieve green growth and development in the solid waste recycling sector.

Abstract

Remote sensing technique to estimate the sea surface salinity has been widely implemented in the seas of various regions. The interface between them was developed using a regression equation like the algorithm in previous research. However, the use of this algorithm for waters in Indonesia, especially in Madura Strait, still requires some adjustment since it is related to the characteristics of different areas in which the algorithm was developed. The development of an applicable local algorithm was performed by finding the best coefficient value in estimating sea surface salinity by considering the value of its lowest NMAE (Normalized Mean Absolute Error). By using salinity and in-situ Rrs(l) (Reflectance of remote sensing) data, we found that the coefficient for the slope was -0.0092, and the intercept was 1.4903. The developed algorithm produces higher accuracy than the existing algorithm, with an NMAE of 0.51%. This NMAE value is smaller than previous research, so this new model can be used to estimate sea surface salinity, particularly in Indonesian sea waters.
