Assessing the Ecosystem Health of Coastal Wetland Vegetation (Suaeda salsa) Using the Pressure State Response Model, a Case of the Liao River Estuary in China

Suaeda salsa (S. salsa) is an important ecological barrier and tourism resource in coastal wetland resources, and assessing changes in its health is beneficial for protecting the ecological health of wetlands and increasing finances. The aim was to explore improvements in the degradation of S. salsa communities in the Liao River Estuary National Nature Reserve since a wetland restoration project was carried out in Panjin, Liaoning Province, China, in 2015. In this study, landscape changes in the reserve were assessed based on Sentinel-2 images classification results from 2016 to 2019. A pressure-state-response framework was constructed to assess the annual degradation of S. salsa communities within the wetlands. The assessment results show that the area of S. salsa communities and water bodies decreased annually from 2016 to 2019, and the increased degradation indicators indicate a state of continued degradation. The area of types such as aquaculture ponds and Phragmites australis communities did not change much, while the estuarine mudflats increased year by year. The causes of S. salsa community degradation include anthropogenic impacts from abandoned aquaculture ponds and sluice control systems but also natural impacts from changes in the tidal amplitude and soil properties of the mudflats. The results also indicate that the living conditions of S. salsa in the Liao River estuary wetlands are poor and that anthropogenic disturbance is necessary to restore the original vegetation abundance.

Development Indicators and Soybean Production in Brazil

Due to its agricultural potential, land extensions, and favorable climate, Brazil is one of the largest producers and exporters of various agricultural products. A significant part of this production is placed in Mato Grosso, the primary national producer of several agricultural commodities. The soybean complex alone produced more than 33 million tons of soybean for the 2019/2020 harvest, representing 27% of national production. The economic potential that the soybean commodity represents is linked to the increase in demand for inputs, planted area, production, and productivity. Given these factors, the present study aims to analyze how the largest municipalities of soybean production behave, and the degree of interaction and positive associations between the economic potential promoted by soybean production and the economic/social development and environmental impacts in the Mato Grosso State, Brazil. The methodology was to categorize the thirty largest soybean producing municipalities, using the factor analysis method for selected indicators. The interpretation is made through the adoption of the Driver-Pressure-State-Impact-Response (DPSIR) framework. The results indicated that the groups formed are not homogeneous in terms of socio-economic and environmental development. The three factors that formed, were interpreted using the DPSIR are characterized by the significant influence of the population, reflect on its development, how economic activities are other and not just agriculture. The second also belongs to the driver in the DPSRI framework group. It is associated with the soybean production indicator, implying larger planting areas, generating jobs focused on agricultural activities. The interpretation is made through the adoption of the Driver-Pressure-State-Impact-Response (DPSIR) framework. The results indicated that the groups formed are not homogeneous in terms of socio-economic and environmental development. The significant influence of the population characterizes the three found factors. The first reflects on the region’s development and how other economic activities (not just agriculture) are carried on. The second also belongs to the driver in the DPSRI framework group, and it is associated with the soybean production indicator, generating jobs focused on agricultural activities. The third group, formed by municipalities in the Amazon region, with environmental factors associated with large geographical areas, extensive native forests, and more significant carbon sequestration, considers the DPSRI framework’s impacts. Showing that there are behavior patterns and taking this into account is the optimal way to use the predictors appropriately. Municipalities are expected to be more reactive to some changes than to others to achieve a good level of development.

Use of Indicators in Strategic Environmental Assessments of Urban-Planning Instruments: A Case Study

The monitoring of the impact of cities on sustainable development initiatives has led several nations to adopt the use of the Strategic Environmental Assessment (SEA) instrument to enhance environmental management efforts. The use of indicators within this process is essential since they enable authorities to monitor and mitigate any adverse effects that may arise as a consequence of urbanization. Over a decade after the implementation of this instrument in Chile, a review of the indicators used in the SEA framework to monitor the impacts of urban planning has yet to be executed. Since there is no standardization of indicators under Chilean regulations, this study applied international classifications including the Pressure-State-Response indicator framework devised by the Organisation for Economic Co-operation and Development (OECD) in addition to the International Organization for Standardization (ISO) Standard 37120. Under these criteria, the environmental-monitoring indicators utilized in the most populous regions in Chile were classified. Results show a limited use of indicators that can be categorized as related to urban-focused environmental monitoring. This paper concludes by posing certain questions that should be considered for future improvements to monitoring impacts generated by urbanization.

Modelling Wetland Eco-hydrological state in Pressure-State-Response framework validating it using Ecosystem service potentiality approach

The present study has tried to model the Eco-hydrological state of wetlands for both pre dam and post dam periods of the Lower Tangon river basin using Pressure-State-Response (PSR) framework with advanced machine learning (ML) algorithms and validated it with Ecosystem service potentiality (ESP) approach along with conventional approaches of validation. All the applied models have explored that 22.48–39.52% wetland under very good EHS zone has converted into 15.52–16.57% relatively lower category of EHS zones indicating the gradual degradation of EHS quality over wider parts of the wetland. The result of model validation has noted the acceptability of all the applied models but performance is found high in the case of REPtree and Bagging models. Expert-based ESP behaves accordingly with the EHS models. Based on the results, the study suggests using ML models for such modelling and used field-based validation approach like ESP.

Membership, Mobilization, and Policy Adoption in the Gilded Age: The Case of the Woman’s Christian Temperance Union

Relatively little is known about how late nineteenth-century associations worked to get their policy goals adopted by state governments. We study this question here, considering the Woman’s Christian Temperance Union (WCTU) and three policies it supported: scientific temperance instruction, increasing the age of consent, and prohibiting tobacco sales to minors. Overall, WCTU-supported legislation was more likely to succeed in states with unified Republican state legislatures, aided by neighboring state adoptions (scientific temperance) and greater WCTU membership (increasing age of consent and prohibiting tobacco sales to minors). These findings are supported by historical evidence, which reveals how WCTU leadership targeted particular states when lobbying for scientific temperance instruction laws and utilized its broad membership base to pressure state legislatures on the other two issues. In total, these results show how one late nineteenth-century membership group was able to facilitate the successful spread of its policies throughout the nation.
