Green Infrastructure in Spatial Planning
Adaptation to climate change is becoming one of the main paradigms for how cities function and develop. The significant role of green infrastructure (GI) as a tool for cities to adapt to climate change is increasingly emphasized among practitioners of spatial planning and in the research literature. Green infrastructure should be understood as "a strategically planned network of natural and semi-natural areas with other environmental features designed and managed to deliver a wide range of ecosystem services. It incorporates green spaces (or blue if aquatic ecosystems are concerned) and other physical features in terrestrial (including coastal) and marine areas".

The Utility of Joint SECAP Plans
The “Joint Sustainable Energy and Climate Action Plans” (Joint SECAPs) introduced by the Covenant of Mayors (CoM) are voluntary tools that favour a joint approach to energy planning and climate change mitigation/adaptation among municipalities in the same territorial area.

Lava Tubes' Radar Observation on Moon and Mars
Lava tubes are tunnel–like structures within lava flows and can vary in diameter, length, and shape. Due to the Moon and Mars both having low–gravity environments, the lava tubes on these celestial bodies can have volumes that are 1–3 orders of magnitude larger than those found on Earth.

Nature-Based Solutions for Urban Carbon Neutrality
The building sector is responsible for nearly 40% of the total global direct and indirect CO2 emissions. Urban green infrastructure, which includes features such as urban trees, vegetation, green roofs, and green facades, are examples of nature-based solutions often employed as municipal climate mitigation and adaptation strategies. This approach offers a range of cost-effective strategies for reducing municipal CO2 emissions and presents compelling public policy co-benefits such as improved urban livability and enhanced environmental conditions.

Methods for Monitoring and Studying Forest Vulnerability
Forests around the world are facing climate change. Increased drought stress and severe heat waves have negatively impacted on forest health, making them more vulnerable and prone to dieback and mortality phenomena. Although the term vulnerability is used to indicate an increased susceptibility of forests to climate change with a worsening of their vigour status that can compromise their ability to respond to further climate extreme events, there are still uncertainties on how to evaluate it. Indeed, evaluation of forest vulnerability is complex both because of some critical issues in the estimation methods used and because of the multiple factors influencing the response of forests to ongoing climate change. A way to assess the vulnerability to environmental stresses is by combining remote sensing and dendroecological data.

Microwave-Assisted Pyrolysis of Waste Plastics
Microwave treatment, owning specific interactions between the electric field and the molecules of treated materials, presents potential advantages in the application of plastic pyrolysis. High value-added liquid oil, gas and solid carbon can be obtained from microwave-assisted pyrolysis (MAP) of plastics. Factors that affect the distribution of pyrolysis products of plastics include the properties of plastics, microwave treatment parameters, microwave absorber, co-pyrolysis, catalysts and reactor design. MAP of plastics has broad application prospects, and large-scale pyrolysis processing devices need to be developed. At the same time, the research platform of MAP simulation of plastics still needs to be developed.

Best Management Practices and Water Use Efficiency
Rice is a water-guzzling crop cultivated mostly through inefficient irrigation methods which leads to low water use efficiency and many environmental problems. Additionally, the export of virtual water through rice trading and the looming water crisis poses significant threats to the sustainability of rice production and food security. There are several alternative rice production methods to improve water use efficiency. These include aerobic rice, direct-seeded rice (DSR), alternate wetting and drying (AWD), saturated soil culture (SSC), drip-irrigated rice, a system of rice intensification (SRI), and smart irrigation with sensors and the Internet of Things (IoT). However, each method has its own advantages and disadvantages. For example, drip-irrigated rice and IoT-based automated irrigation are not feasible for poor farmers due to the high production costs associated with specialized machinery and tools. Similarly, aerobic rice, drip-irrigated rice, and the SRI are labor-intensive, making them unsuitable for areas with a shortage of labor. On the other hand, DSR is suitable for labor-scarce areas, provided herbicides are used to control weeds.

Geothermal Anomalies in the Neoproterozoic Arabian Shield
Certain areas of the Kingdom of Saudi Arabia (KSA) are assessed in order to map potential geothermal energy zones. To evaluate high-resolution aerial magnetic data, spectral depth analysis using a modified centroid approach was used. The calculated geothermal parameters were gridded in order to delineate the regions characterised by a shallow Curie point depth (CPD) and a high geothermal gradient (GG) as well as a high heat flow (HF).

Influence of Digital Economy on Carbon Dioxide Emissions
Massive emissions of greenhouse gases, primarily carbon dioxide, are endangering not only sea level rise and extreme weather but also agricultural production and human life. Digital technologies such as big data, cloud computing, and artificial intelligence have been increasingly integrated into different commercial and social domains. The subsequent wave of the digital economy has become a massive force in transforming the traditional economic model, restructuring the global value chain, and promoting the economy’s green transformation.
