Abstract Watershed has played an important source of ecosystem services (ES). The Krueng Peusangan watershed (KPW) is considered to be the “lungs” and ecological border in the central region of Aceh, Indonesia. This study aims to monitor landscape patterns in the watershed area of 2009-2019 and to predict changes in 2039 and their relationship with infiltration. The selection of this research area is due to the notion that KPW is one of the numerously deforested watersheds in the country. Temporal spatial monitoring of landscape (land use/cover, LUC) patterns are required to inform policy and support future spatial management planning towards sustainability. Landscape patterns changes in KPW, including the extent of loss and addition of forest over the last few years, have not been quantified. In constructing the regional development policies, information regarding the effects of landscape changes and climatic patterns on ecosystem services is essential. Therefore, the knowledge development of this relationship is encouraged. The comparison value between potential and actual infiltration could identify the watershed category. The upstream area of KPW is classified as a significantly critical watershed due to LUC changes. Therefore, it is deemed necessary to improve the absorption zone for the continuation of groundwater protection.

In recent decades, substantial changes have occurred in the spatial structure and form of landscapes in metropolises; these have greatly impacted ecosystem provision capacities. Clarifying the impact mechanism of landscape patterns on ecosystem services can provide insights into regional ecological conservation and sustainable development measures. Although previous studies have explored the impacts of landscape patterns on ecosystem services at multiple scales, few studies have been conducted using the buffer gradient analysis approach. Using land-use/cover change data, this study measured the evolution of spatiotemporal features of landscape patterns and ecosystem services value (ESV) with 1, 2, and 3 km buffer-zone scales in Wuhan, China. Econometric models were then used to analyze the impacts of landscape patterns on ecosystem services at different buffer-zone scales. The results demonstrated that rapid urbanization in Wuhan has led to significant changes in landscape patterns, and the landscape pattern metrics exhibited significant spatial heterogeneity. The ESV in Wuhan exhibited a steady decline during the study period. Hydrological regulations and waste treatment functions contributed to the largest proportion of ESV, and raw material production functions contributed to the lowest proportion. Landscape pattern metrics exerted a significant influence on ESV; however, this influence varied greatly. The results of this study provide a new understanding of the influence mechanism of landscape patterns on ecosystem services at 1, 2, and 3 km buffer-zone scales. These findings are critical for facilitating landscape planning and regional sustainable development.

Abstract The research aimed to determine the impact studied factors represented by (people’s activities, government activities, natural factors) on the deterioration of natural pastures in the Governorate of Al-Muthanna the point of view of agricultural employees in the governorate. The research included all agricultural employees with a preparatory scientific qualification in agriculture and above in the governorate their number is (94) employees. A questionnaire was prepared to collect the data necessary to achieve the objectives of the research. It consisted of two parts. The first part included the factors related to the employees, which are (term of service, academic achievement, participation in extension activities, job position and work location). The second part included a measure to identify the agricultural employees’ the point of view of on the factors affecting the deterioration of natural pastures. It consists of (46) section spread over (3) field covered by the research. The results showed that government activities have the most impact on the deterioration of natural pastures, it was found a statistically significant difference in the respondents’ point of view about the influence of the studied factors according to their personal characteristics. The researchers concluded the necessity of agricultural expansion in pasture lands and industrial investments, as well as the importance of personal factors in assigning employees who can work in the development of natural pastures, and the researchers recommend activating government laws for the protection of natural pastures to prevent abuses (people’s activities, government activities) that contributed greatly to the deterioration of vegetation cover in the research area and taking into account the factors studied in the selection of workers in the development of natural pastures in the research area.

Regional development policies based on local potential triggers a shift in the economic structure of territories. Exogenous and endogenous factors determine potential of regional development and it is necessary to use different indicators and methods to its evaluation. For the paper purpose, it is required to define metropolitan and peripheral functions as well as urban areas in the form of geographic models, depicting their spatial distribution in the European Union (EU). Nowadays, regions are increasingly becoming the drivers of the economy. All regions possess development opportunities – however, use these options enough, and hence the competitiveness of regions must be efficient enough. The paper focuses on dividing the EU NUTS 2 regions based on geographic models of the European economy into efficient and inefficient ones and identifying an optimal benchmark for inefficient regions as a strategy for enhancing their economic structure to measure regional efforts and progress.

It is an effective method to study the value change of ecological services based on land use and cover change information. This paper analyzed the land use and cover change information in the research area, which is based on the remote sensing images and social statistics data of 2005, 2010, and 2015, and then, quantitative estimation of the ecosystem service value was performed. Yangtze-Huaihe river basin, China is a fragile ecological area, which is selected as the research area. During 2005-2015, the area of cultivated land and construction land was the main land use types in the study area, the land use and cover change in the study area were obvious, which was characterized by the increasing of construction land area and the decreasing of cultivated land area, and the total ecosystem services value in the research area has been decreasing continuously, the value from 34.376 billion yuan in 2005 to 26.161 billion yuan in 2015.
