Backgrounds of Agroforestry and Social Forestry in Indonesia
Smart agroforestry (SAF) is a set of agriculture and silviculture knowledge and practices that is aimed at not only increasing profits and resilience for farmers but also improving environmental parameters, including climate change mitigation and adaptation, biodiversity enhancement, and soil and water conservation, while assuring sustainable landscape management. Indonesia has the third largest area of tropical forest as well as the second largest biodiversity and the second highest number of indigenous medicinal plants in the world. It covers 10% of the global tropical forest with 50% of the world’s biodiversity, flora, mammals, amphibians, reptiles, primates, and birds, and provides 25% of the medicinal plants for human health. Social Forestry is a sustainable forest management system implemented in state forests or private/customary forests by local or traditional indigenous communities as the main actors to improve well-being, environmental balance, and sociocultural dynamics in the form of village forests, community forestry, community plantation forests, traditional forests, and forestry partnerships. Social and economic perspectives on SF development received more attention than environmental perspectives. Economic opportunities are deemed to be the main benefit of social forestry, while social and environmental challenges seem to be the major barriers to implementation. Three main keys in the SF program are how to improve the institutional governance, forest governance, and business governance. SF management needs innovation, technology, and collaboration to provide broader benefits for communities in terms of forest land and the use of forest products.

Combustion and Stubble Burning Effluent Emissions
Combustion is an essential process for humanity, but it has created turbulence in society due to the pollutant emissions from the partial completion of its process and its byproducts. According to the system of air quality and weather forecasting and research (SAFAR), stubble burning’s contribution to air pollution (as PM) was 25% in 2021, 32% in 2020, and 19% in 2019, while the fire count between September and November was 71,304 in 2021, and 83,002 in 2020, respectively. This has been known to directly affect Delhi’s air quality index (AQI). Combustion effluents are generated in response to the behavior of the burning process and product toxicity, which further resides in the fire plot (orientation and fuel’s shape), material composition, oxygen concentration, and temperature.

Dust-Associated Perfluoroalkyl and Polyfluoroalkyl Substances
The occurrence of sand and dust storms (SDSs) is essential for the geochemical cycling of nutrients; however, it is considered a meteorological hazard common to arid regions because of the adverse impacts that SDSs brings with them. One common implication of SDSs is the transport and disposition of aerosols coated with anthropogenic contaminants. Studies have reported the presence of such contaminants in desert dust; however, similar findings related to ubiquitous emerging contaminants, such as per- and poly-fluoroalkyl substances (PFAS), have been relatively scarce in the literature.

Adsorption Techniques for Lead Removal
The long-term sustainability of the global water supply, with a paramount emphasis on cleanliness and safety, stands as a formidable challenge in modern era. In response to this pressing issue, adsorption techniques have emerged as pivotal and widely recognized solutions for the removal of hazardous pollutants, with a particular emphasis on lead adsorption from wastewater.

Different Domains of Dengue Research in Malaysia
The systematic review provided some useful insights into recommendations for the control of dengue infection in Malaysia. The efforts of translating knowledge into appropriate attitude and preventive practices regarding dengue should be conducted into more sustainable strategies by the active engagement of communities, inculcation of positive culture, improvements of health campaign, and co-operation with faith-based organisations to spread awareness on dengue prevention and control measures.

Contaminations in Ion-Adsorption Type Rare Earths Tailings
Rare earth elements, particularly middle and heavy rare earth, are among the most valuable resources in the pursuit of a greener economy. The production of middle and heavy rare earth elements heavily relies on ion adsorption, which constitutes over 80% of global output and is centered in southern China. Unfortunately, the extensive mining activities have led to severe environmental pollution, resource depletion, and risks to human health.

Utilizing Mediterranean Plants to Remove Contaminants
The use of contaminated soils in food production imposes the need for the reduction in heavy metals concentrations, using various techniques, in order to eliminate the toxic effects of pollution and ensure safety in the consumption of agricultural products. Phytoremediation is a promising, effective, and publicly acceptable method to remove soils’ toxicity. The Mediterranean basin is a region of distinct climatic conditions with temporal variability and great floristic heterogeneity. Due to the high variability in landscapes paired with the warm, dry summers and cool, wet winters, the Mediterranean hosts significant plant diversity, including numerous endemic and rare plant species

Soil Nanomanagement and Mushrooms
Soil is the main component in the agroecosystem besides water, microbial communities, and cultivated plants. Several problems face soil, including soil pollution, erosion, salinization, and degradation on a global level. Many approaches have been applied to overcome these issues, such as phyto-, bio-, and nanoremediation through different soil management tools. Mushrooms can play a vital role in the soil through bio-nanoremediation, especially under the biological synthesis of nanoparticles, which could be used in the bioremediation process.

Environmental Taxes
The environmental tax is designed to motivate companies and citizens to seek solutions that limit the negative aspects of running a business. Environmental taxes or ecological taxes are defined in various ways. They can be defined as a non-returnable payment to the state that is levied on the object of taxation. The functions to be fulfilled by the environmental tax can be divided into three categories, i.e., redistributive, incentive, and fiscal. Redistribution consists of the division of the obtained funds and their allocation, for example, to environmental funds. The fiscal function allows the accumulation of funds for the state budget.
