“…Further, Shabbir and Ahmad, 2016 [101] found water resources in the Rawalpindi region vulnerable to climatic and socio-economic factors. Similarly, studies for Multan, Sahiwal, and Lahore have reported their problems (e.g., crops productivity, floods, CO 2 discharge, land-use change, and pollution) [102][103][104][105][106][107]. The rest of the 32 districts have zero or negligible values in the 'very high' vulnerability zone.…”

China-Pakistan economic corridor (CPEC), a critical part of the Belt and Road initiative (BRI), is subjected to rapid infrastructure development, which may lead to potential eco-environmental vulnerability. This study uses multi-source geo-information, and the multi-criteria decision-making (MCDM)-based best–worst method (BWM) to quantify the baseline eco-environmental vulnerability of one key CPEC sector—the Punjab province. The Punjab province is an important connection between northern and southern CPEC routes in Pakistan. In this study, we have established an indicator system consisting of twenty-two influential factors in a geospatial database to conduct eco-environmental vulnerability analysis. The overall setup is supported by a geographic information system (GIS) to perform spatial analysis. The resulting map was categorized into five vulnerability levels: very low, low, medium, high, and very high. The results revealed that the overall eco-environmental health of the Punjab province is reasonably good as 4.64% and 59.45% area of the key sector lies in ‘very low’ and ‘low’ vulnerability categories; however, there also exist highly vulnerable areas, particularly in the proximity of CPEC projects. Although high vulnerability areas constitute a very small percentage, only 0.08% of the Punjab province, still, decision-makers need to be aware of those regions and make corresponding protection strategies. Our study demonstrated that the MCDM-BWM-based EVA model could be effectively used to quantify vulnerability in other areas of CPEC. The findings of the study emphasize that management policies should be aligned with research-based recommendations for ecological protection, natural resource utilization, and sustainable development in regions participating in Belt and Road Initiative (BRI).

“…In recent years, there has been considerable research on land use change and ecosystem services, which can be divided into two categories: The first type is based on different models, such as CLUE−S model [ 55 ], CA−Markov model [ 56 ], etc., based on land use conditions in different scenarios to predict the impact of future land use changes on the value of ecosystem services. These scenarios generally include three scenarios: natural growth scenario, economic development scenario, and ecological protection scenario.…”

Exploring the changes of ecosystem services value caused by land use transformation driven by urbanization is crucial for ensuring the safety of the regional ecological environment and for enhancing the value of ecosystem services. Based on the land use remote sensing data during the rapid urbanization development period of Hubei Province from 1995 to 2015, this study analyzed the characteristics of land use/land cover change and land use transformation. The spatial–temporal response characteristics and evolution of ecosystem services value (ESV) to land use transformation driven by urbanization were measured by equivalent factor method, spatial autocorrelation analysis, hot spot analysis and gravity model. We found that: (1) Driven by urbanization, the most significant feature of land use transformation in Hubei Province was the expansion of the built-up land and the significant reduction of cropland and forest, among which 90% of the new built-up land was converted from cropland and forest. (2) This land use transformation became the main source of ESV losses. Especially, the sharp increase of the built-up land from 2010 to 2015, occupying cropland and forest, resulted in ESV losses of nearly USD 320 million. The service capacity of climate regulation, soil conservation, gas regulation and food production undertaken by cropland and forest decreased. (3) The ecosystem services value in the study area showed spatial distribution characteristics of high in the west and low in the middle and east regions. The center of gravity of ESV shifted from northwest to southeast. Due to the sharp increase of the built-up land from 2010 to 2015, the center of gravity shift rebounded. This study can help policymakers better understand the trade−offs between land use transformation and ecosystem services driven by urbanization.

“…Kondisi penurunan kualitas air tanah secara kondisi fisik dari penyusun batuan dapat dikatagorikan sebagai kerentanan (Ciemens et al, 2020;. Kerentanan air tanah merupakan kondisi masuknya unsur satuan, komponen fisika, kimia atau biologi ke dalam air bawah tanah dan/atau berubahnya tatanan air bawah tanah oleh kegiatan manusia oleh proses alami yang mengakibatkan mutu air bawah tanah turun sampai ke tingkat tertentu sehingga tidak lagi sesuai dengan peruntukannya (Akhtar et al, 2020;BSN, 2012). Penilaian kerentanan air tanah memerlukan pendekatan sistematik empiris dikarenakan tidak dapat diidentifikasi secara langsung secara kenampakan fisik (visual) (Guettaia et al, 2017;Vienastra & Febriarta, 2018).…”

Kota Saumlaki merupakan ibu kota Kabupaten Maluku Tenggara Barat, yang secara geografis berada di ujung Pulau Yamdena bagian selatan dan merupakan bagian dari Pusat Kegiatan Strategis Nasional (PKSN) Saumlaki di Provinsi Maluku. Sebagai kawasan strategis Kota Saumlaki juga menjadi pusat pemerintahan dan memiliki laju pertumbuhan penduduk meningkat dan pembangunan yang semakin intensif. Dampak dari aktivitas tersebut dari ketersediaan sumber daya air (air baku) dapat mengalami defisit (kekurangan dalam mencukupi kebutuhan). Meningkatnya kebutuhan air baku dalam jumlah yang tinggi dapat mengakibatkan penurunan daya dukung sumber daya air secara kuantitas maupun kualitas. Penurunan kualitas air dapat ditimbulkan dari sisa hasil penggunaan air secara domsetik (rumah tangga), kegiatan perdagangan (kantor/pasar) maupun kegiatan industri. Menurunnya kualitas air tanah melebihi baku mutu air dapat mengakibatkan masalah kesehatan. Selain dari pengelolaan limbah air, pelu juga ditinjau dari sisi faktor lingkungan (geologi) dari sifat batuan terhadap kerentanan pencemaran. Untuk mengetahui hal tersebut maka tujuan dari penelitian ini adalah mengetahui potensi kerentanan air tanah terhadap pencemaran pada batugamping koral dengan pedekatan GOD di Kota Saumlaki. Kerentanan GOD didasarkan atas sifat batuan dalam meloloskan air tanah yaitu, tipe akuifer (G), litologi akuifer (O) dan kedalaman tinggi muka air (D). Berdasarkan hasil pengukuran diketahui di Kota Saumlaki dan sekitarnya terdapat dua (2) kelas, yaitu kerentanan tinggi dan kerentanan ekstrim. Pusat Kota Saumlaki termasuk kerentanan ekstrim yang dipengaruhi oleh kedalaman air tanah yang dangkal, dan sifat batuan yang porus dalam potensi mempercepat mengalirkan pencemaran.
