In this study, the human activity intensity on the Qinghai–Tibet Plateau (QTP) from 1990 to 2020 was measured based on the quantitative model of land use data and the actual regional background, and the underlying natural and socioeconomic determinants were investigated using spatial econometric methods. The results demonstrate that (1) the human activity intensity in QTP has increased by 11.96%, and there are differences in different spatial scales; the areas with high human activity intensity are distributed in the Hehuang Valley where Xining City and its surrounding areas are located, as well as the One-River and Two-River Area where Lhasa City and surrounding areas are located. (2) Human activity intensity has significant positive spatial spillover, suggesting that local changes will cause changes in the same direction in adjacent areas. (3) The human activity intensity in QTP is affected by various determinants. Concerning socioeconomic factors, the economic level has no significant impact on the human activity intensity in QTP, which differs from the general regional law. Both urbanization and traffic conditions have a significant positive effect, and the impact intensity continues to increase. Concerning natural factors, topographic relief has a significant positive effect; the impacts of temperature and vegetation coverage have changed from insignificant to a significant positive effect; the impacts of precipitation and river network density have not been verified; there is no linear relationship between altitude and human activity intensity in the entire QTP, while it exists in local regions. Finally, this study proposes three policy implications for the realization of a more harmonious human-environment relationship in QTP.</p></div>","PeriodicalId":52374,"journal":{"name":"Geography and Sustainability","volume":"4 4","pages":"Pages 294-304"},"PeriodicalIF":9.7,"publicationDate":"2023-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49841286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, mechanisms underlying LUCC determination of water-balance processes at the basin scale remain unclear. In this study, the Soil and Water Assessment Tool (SWAT) model and partial least squares regression were used to detect the effects of LUCC on hydrology and water components in the Zuli River Basin (ZRB), a typical watershed of the Yellow River Basin. In general, three recommended coefficients (<em>R</em>² and <em>E</em>_ns greater than 0.5, and <em>P</em>_bias less than 20%) indicated that the output results of the SWAT model were reliable and that the model was effective for the ZRB. Then, several key findings were obtained. First, LUCC in the ZRB was characterized by a significant increase in forest (21.61%) and settlement (23.52%) and a slight reduction in cropland (–1.35%), resulting in a 4.93% increase in evapotranspiration and a clear decline in surface runoff and water yield by 15.68% and 2.95% at the whole basin scale, respectively. Second, at the sub-basin scale, surface runoff and water yield increased by 14.26%–36.15% and 5.13%–15.55%, respectively, mainly due to settlement increases. Last, partial least squares regression indicated that urbanization was the most significant contributor to runoff change, and evapotranspiration change was mainly driven by forest expansion. These conclusions are significant for understanding the relationship between LUCC and water balance, which can provide meaningful information for managing water resources and the long-term sustainability of such watersheds.</p></div>","PeriodicalId":52374,"journal":{"name":"Geography and Sustainability","volume":"4 1","pages":"Pages 19-28"},"PeriodicalIF":9.7,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49892135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The data indicates that 85.4% of the water supply systems were fully functioning, 9.1% were partially functioning, and 5.5% were not functioning. In the regression analysis, good management is positively associated with functionality and a high investment per capita is negatively associated with the functionality. The latter suggests the need for comprehensive economic analysis in the feasibility study in scattered housing sites and remote-undeveloped areas. We also found that high community participation at the beginning of the project was associated with the not functioning system, while women’s participation was positively associated with the functionality. Furthermore, the household connection is more likely to be functioning than communal connection. BBN analysis shows if the beneficiaries do not pay for water, the probability of not functioning systems is 20 times higher than systems with fee collection. Moreover, the combination of strong management, strong financial status, and household connection rather than communal connection increases the probability of fully functioning to 98%. Improvement of data collection is also necessary to monitor the current conditions of all PAMSIMAS systems in Indonesia. This study offers a country-level perspective for better implementation of the community-based rural water supply and sanitation program in developing countries.</p></div>","PeriodicalId":52374,"journal":{"name":"Geography and Sustainability","volume":"4 1","pages":"Pages 29-38"},"PeriodicalIF":9.7,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49906982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This dominance is due to lower production costs in coal-fired power plant generation. However, this low price is only based on monetary costs and ignores the social costs. Therefore, this study aims to quantify the social costs of coal-fired generation. Using QUERI-AirPacts modeling, the present study quantifies the social costs resulting from the Tenayan Raya coal-fired generation in Riau, Indonesia. It includes the levelized cost of electricity and health costs into the generation costs. After that, this study calculates the net present value, internal rate return, and project payback period. The study found that as much as $50.22/MWh was the levelized cost of electricity. While $15.978/MWh or $0.015978/kWh was the social cost that was not included in the generating cost. At the electricity production level of 1,380,171.69 MWh per year, there is an expected extra cost of $22,052,383.30 uncounted when externalities are included. For instance, the net present value (NPV) is lower and even negative when external costs are included (–$24,062,274.19) compared to $176,108,091.52 when externalities are not considered. The internal rate of return (IRR) is much higher when the social costs are not considered. The payback period is also shorter when the social costs are excluded than when the externalities are included. This global number indicates that the inclusion of external costs would impact NPV, IRR, and the payback period. This result implies that the government should internalize the external cost to stimulate the electricity producers to conduct cost-benefit analyses. The cost-benefit analysis mechanism would lead the producers to be more efficient.</p></div>","PeriodicalId":52374,"journal":{"name":"Geography and Sustainability","volume":"4 1","pages":"Pages 39-48"},"PeriodicalIF":9.7,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49906981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Identification of potential landslides, estimation of the degree of damage and potential losses of elements at risk, and control of the loss are the major tasks of landslide risk management. Resilience is defined as a social system’s comprehensive abilities to cope with disasters, including the abilities to prepare, anticipate, preserve, absorb, respond, resist, recover, mitigate, learn, and adapt. As an indispensable role, resilience enables more rational landslide risk management for social sustainability. However, quantitative landslide risk management does not pay sufficient attention to the role of resilience. Hence, in this paper, the role of resilience in a landslide risk management framework is systematically discussed. A quantitative landslide risk management framework consists of hazard analysis, exposure analysis, risk estimation, risk evaluation, and risk control. In hazard analysis, resilience assessment could help identify potential landslides that could cause significant damage due to the poor resilience of the elements at risk. Resilience assessment in exposure analysis might aid in identifying the most vulnerable elements or regions to certain landslides. Consideration of resilience in risk estimation aids in the calculation of indirect losses and improves the results of direct losses analysis. In risk evaluation, resilience as a disaster-coping ability will impact the social system's landslide risk tolerance threshold. Enhancing resilience is an essential strategy to reduce the vulnerability of social systems. We also proposed that the efficient use of risk information will increase the accuracy of landslide resilience assessments.</p></div>","PeriodicalId":52374,"journal":{"name":"Geography and Sustainability","volume":"4 1","pages":"Pages 70-83"},"PeriodicalIF":9.7,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49906984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tobler’s first law of geography (TFL) states “near things are more related than distant things”. Evidence suggests that TFL is not infallible for sustainability issues. Recently, the integrated framework of metacoupling (MCF; human-nature interactions within as well as between adjacent and distant systems) has been applied to analyze the interactions between nearby and distant coupled human and natural systems simultaneously. However, previous work has been scattered and fragmented. It is crucial to understand the extent to which TFL and MCF apply across pressing issues in sustainability. Therefore, we reviewed and synthesized sustainability literature that used TFL and MCF across seven major topics: land change, species migration, tourism, trade, agricultural development, conservation, and governance. Results indicate MCF had a much broader applicability than TFL for these topics. The literature using MCF generally did not or likely did not obey TFL, especially in trade, governance, and agricultural development. In the TFL literature, most topics obeyed TFL, except for species migration and trade. The findings suggest the need to rethink and further test TFL’s relevance to sustainability issues, and highlight the potential of MCF to address complex interactions between both adjacent and distant systems across the world for global sustainability.</p></div>","PeriodicalId":52374,"journal":{"name":"Geography and Sustainability","volume":"4 1","pages":"Pages 6-18"},"PeriodicalIF":9.7,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49906986","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The multiple dimensions and implications of food systems and the international agenda’s priorities namely the “Right to adequate Food”, “Food Sovereignty” and the “Right to Land”, were used as our conceptual framework. To work out how land is being considered in food sectorial policies, both quantitative and qualitative methods were applied to examine ten Portuguese national food-related policies. Results are showing a lack of consideration for land access and land preservation, needed all along the food chain to build a national sustainable food system. On the other hand, there is a gap between current grassroots priorities international agendas and food-related national policies.
