Methods for Intensifying Biogas Production from Waste
The topic of intensification of bioprocesses is widely discussed in agricultural countries and countries with a large amount of organic waste. Therefore, the study of bioprocess intensification methods can help increase qualitative and quantitative indicators of biogas yield by using a combination of intensification methods.

COVID-19 Affect Our Perception of Sustainability
Since the World Health Organization (WHO) declared the outbreak of severe acute respiratory syndrome COVID-19 virus 2 (COVID-19) virus disease 2 (SARS-CoV-2) on 9 January 2020, the entire world has been exceptionally interested in examining the impact of this pandemic on people and the environment. The pandemic led to unprecedented measures to halt air traffic and close factories due to lockdowns, economic closures, and the stopping of transportation of all kinds. The decline in the use of coal by power plants, oil refining, and steel manufacturing had a beneficial effect on air pollution and caused a decrease in carbon dioxide emissions. Moreover, the concept of sustainability has become more prevalent, reflecting the increasing awareness of the responsibility placed on every member of society. Sustainability is the quality and quantity of change that meets our needs without destroying the giving planet, which is the hope for the survival of future generations.

Models of the Structure of Humic Substances
Natural organic matter, including humic substances (HS), comprises complex secondary structures with no defined covalent chemical bonds and stabilized by inter- and intra-molecular interactions, such as hydrogen bonding, Van der Waal’s forces, and pi-pi interactions. The latest view describes HS aggregates as a hydrogel-like structure comprised by a hydrophobic core of aromatic residues surrounded by polar and amphiphilic molecules akin a self-assembled soft material. A different view is based on the classification of this material as either mass or surface fractals. The former is intended as made by the clustering of macromolecules generating dendritic networks, while the latter have been modelled in terms of a solvent-impenetrable core surrounded by a layer of lyophilic material.

Cover Crops as a Soil Water Management Strategy
Cover crops can play a more prominent role in water management; however, the more widespread use of cover crops may be hindered by the inconsistencies of experimental data demonstrating cover crop effects on soil water retention, as well as cover crop effect inconsistencies arising from complex interactions between soil carbon, water, and land management.

Regulatory Approach to Ocean Plastics
The research investigates the problems and maps the solutions to the serious threat that plastics pose to the oceans, food safety, and human health, with more than eight million tons of plastic debris dumped in the sea every year. The aim of this study is to explore how to better improve the regulatory process of ocean plastics by integrating scientific results, regulatory strategies and action plans so as to limit the impact of plastics at sea. Adopting a problem-solving approach and identifying four areas of intervention enable the establishment of a regulatory framework from a multi-actor, multi-issue, and multi-level perspective. The research methodology consists of a two-pronged approach: 1. An analysis of the state-of-the-art definition of plastics, micro-, and nanoplastics (respectively, MPs and NPs), and 2. The identification and discussion of loopholes in the current regulation, suggesting key actions to be taken at a global, regional and national level. In particular, the study proposes a systemic integration of scientific and regulatory advancements towards the construction of an interconnected multi-tiered (MT) plastic governance framework. The milestones reached by the project SECURE at UiT - The Arctic University of Norway provide evidence of the strength of the theory of integration and rights-based approaches. The suggested model holds substantial significance for the fields of environmental protection, food security, food safety, and human health. This proposed MT plastic governance framework allows for the holistic and effective organization of complex information and scenarios concerning plastics regulation. Containing a clear definition of plastics, grounded on the precautionary principle, the MT plastic framework should provide detailed mitigation measures, with a clear indication of rights and duties, and in coordination with an effective reparatory justice system.

Morphological Effects of Sodium Salinity on Rice
Sodium salinity negatively affects and reduces yields in international agricultural systems. This stress decreases crop growth and development, causing tissue death, flowering abortion, and senescence of the fertilized embryo, and negatively affects enzymatic activity, protein synthesis, among other processes. Rice is a cereal of great international demand for its nutritional properties and its productivity is affected by the presence of salts in agricultural surfaces. The main factors that trigger the decrease in growth under salt stress are adverse changes in morphological structures, which undergo physiological changes due to salinity.

Bioenergy Technologies and Waste Management Practices in Ghana
Finding sustainable solutions to the increasing waste generation in Ghana has received a lot of attention. Through several waste-to-energy processes, the energy potential of municipal solid waste has recently witnessed significant technological advancements. The Renewable Energy Master Plan has projected the production of about 122 MWp from waste-to-energy installations by 2030 in Ghana.

Cultural Dimensions of Climate
Cultural Dimensions of Climate means that climatic events express the dynamics of the Earth’s oceans and atmosphere, but are profoundly personal and social in their impacts, representation and comprehension. Knowledge of the climate has multiple scales and dimensions that intersect in our experience of the climate. The climate is objective and subjective, scientific and cultural, local and global, and personal and political. These divergent dimensions of the climate frame the philosophical and cultural challenges of a dynamic climate. Drawing on research into the adaptation in Australia’s Murray Darling Basin, this paper outlines the significance of understanding the cultural dimensions of the changing climate.
