DPSIR Assessment on Ecosystem Services
The DPSIR framework (Driver – Pressure – State – Impact – Response) is a useful tool to assess and investigate the cause-effect within an ecosystem to aid better systems - thinking approach for stakeholders, policymakers and governance managers to draft response measures. The DPSIR framework helps to identify and analyse the different effects of human activities over the ecosystem services and human well-being in the different ecosystems such as estuarine, delta, river, coastal, etc. The varied human activities involves mining, construction, fishing, infrastructure development, etc. The DPSIR study shows a holistic view on several interlinked pressures and state changes in the ecosystems, also supporting the development of some potential responses to form systematic, sustainable approaches for mitigating and adapting the impacts caused by human activities. This contribution describes the application of DPSIR framework to study the impacts of sand mining and sand consumption in the Vietnam's Mekong Delta ecosystem services,

DPSIR Model
       The Driving force – Pressure – Status – Impact - Response (DPSIR) framework has been widely used in literature to analyse environmental problems. The DPSIR facilitates the investigation of all the possible cause-effect relationships and to plan appropriate technological responses.  This contribution shows an application of the DPSIR to the remediation of contaminated sites, exploiting the case study of the Mar Piccolo di Taranto (Southern Italy). Methodologically, several references were considered, whose information was classified according to the logical scheme of the DPSIR. Among the results it is interesting to observe how, due to its natural hydrogeological network conformation, the Mar Piccolo represents the final receptor of pollutants from industrial, anthropic and agricultural activities. The mobility of contaminants from sediments to the water column and the subsequent bioaccumulation into marine organisms pose a serious threat of unacceptable magnitude to human safety. Responses may concern restriction of area use, control of pollution fonts as well as the implementation of suitable contaminated marine sediment remediation measures. It is noted that the preliminary organization of the existing data can lead to the development of a DPSIR-based Environmental Decision Support System (EDSS).

Dripping Rainfall Simulators for Soil Research
Rainfall simulators represent often-used equipment for soil research. Depending on their performance, they could be appropriate for some soil research or not. Dripping rainfall simulators (DRS) can provide rainfall that corresponds to natural rainfall, except in terms of the drop size distribution and wetted area. However, usually there are more factors that do not correspond to natural rainfall, such as the median drop size, volume and kinetic energy. The sizes of the drops generated by the simulator drippers are mostly in the range between 2 and 6 mm, while the number of drops smaller than 2 mm is relatively small. The intensity and duration of the simulated rain can be successfully produced to match natural values, with the most frequently simulated short-term rainfall of a high intensity. Most simulations were conducted at a fall height of up to 2 m, and then their number gradually decreases as the height gets closer to 5 m. Most simulations (58.6%) occur in the range between 20–90% KE, then 33.0% in a range of 90–100%, with only 8.4% lower than 20% KE.

Driving Cycles for Estimating Vehicle Emission Levels
Standard driving cycles (DCs) and real driving emissions (RDE) legislation developed by the European Commission contains significant gaps with regard to quantifying local area vehicle emission levels and fuel consumption (FC). The aim of this paper was to review local DCs for estimating emission levels and FC under laboratory and real-world conditions. This review article has three sections.

Driving Factors for R&D Intensity
Research and development (R&D) has long been recognized as an important component of sustainable development, with a key role in the combatting of climate change. Moreover, R&D activity is increasingly acknowledged as an important contributing factor to global post-pandemic economic recovery. However, little is known about the determinants of R&D intensity (the share of R&D expenditure in GDP) and countries have repeatedly missed their set targets for this indicator.

Driving Factors of Ecosystem Services
The optimization of tree structure contributes to the improvement in Ecosystem service (ES) provision and the regulation capacity. Species diversity plays an important role in provision services, while functional diversity is equally important in regulation services. Plant root functional traits can not only help regulation services but also determine the species and structure of rhizosphere microbial communities. The response of ES to a certain factor has been extensively reviewed, but the interaction of multiple driving factors needs to be further studied, especially in how to drive the supply capacity of ES in multi-factor and multi-scale ways. Clarifying the driving mechanism of ES at different scales will help to improve the supply capacity of the ecosystem and achieve the goal of sustainable development.

Driving Factors on Flood in Cambodia
Flooding in Cambodia, divided into riverine and flash floods, is subject to a multitude of common driving factors. As the MRC rightly noted, flooding in the country can be aggravated by numerous factors, including but not limited to climate change, infrastructure development, dam construction, land cover/use change, or land clearing.

Driving Forces behind Climate Change
Climate change occurs through a complex set of interactive driving forces. According to the Intergovernmental Panel on Climate Change sixth assessment report (AR6; https://wg1.ipcc.ch/index.php/ar6/sixth-assessment-report-ar6; Accessed on 5 November 2022), human activity is the main driving force of climate change, whereas others contend that natural factors are also main causes.
