Stadt Huys Site
The Stadt Huys (an old Dutch spelling, meaning city hall) was the very first city hall in New York City built in 17th-century during Dutch settlement (New Amsterdam). It stopped function in 1679 due to safety. It is located at the 71 Pearl Street today. The Stadt Huys block archaeology project was the first large scale archaeological excavation in New York City in 1979-1980. At the time it was excavated, it was one of the most expensive and most productive projects of urban archeology undertaken in an American city. A lot of logistical procedures for urban archaeology had to be developed as the project evolved. Most of these procedures have become a model for performing large-scale excavations in the city.

Nanoparticles and Their Role in Heavy Metal Bioremediation
Physical and chemical techniques are used to remove heavy metals (HMs) from contaminated soil. Microbial-metal interaction, a novel but underutilized strategy, might be used to lessen the stress caused by metals on plants. For reclaiming areas with high levels of heavy metal contamination, bioremediation is effective and environmentally friendly. Nanotechnology greatly improves the process of bioremediation, and its application in heavy metal bioremediation.

UN Sustainable Development Goals
Reaching the land-related UN Sustainable Development Goals (SDGs) and similar goals articulated by the EU Green Deal (GD) by 2030 presents a major challenge and requires a pragmatic approach focused on joint learning by land users (mostly farmers), researchers and other stakeholders in “Living Labs” and system experiments at experimental farms of research organizations. Defining specific indicators and thresholds for ecosystem services in line with land-related SDGs is crucial to establish “Lighthouses” that can act as inspiring examples if they meet the various thresholds.

Nutriepigenomics in Environmental-Associated Oxidative Stress
Complex molecular mechanisms define our responses to environmental stimuli. Beyond the DNA sequence itself, epigenetic machinery orchestrates changes in gene expression induced by diet, physical activity, stress and pollution, among others. Importantly, nutrition has a strong impact on epigenetic players and, consequently, sustains a promising role in the regulation of cellular responses such as oxidative stress. As oxidative stress is a natural physiological process where the presence of reactive oxygen-derived species and nitrogen-derived species overcomes the uptake strategy of antioxidant defenses, it plays an essential role in epigenetic changes induced by environmental pollutants and culminates in signaling the disruption of redox control.

Sustainability Reporting in Extractive Industries
Sustainability reporting is one of the tools that contribute to incorporating sustainable development in the design of extractive operations (i.e., “Design for Sustainability”), and the demand for sustainability reports is increasing due to the increased focus on sustainable development and sustainable financing efforts. The extractive industries are believed to have unique strengths to contribute to achieving the Sustainable Development Goals. Nonetheless, companies are expected to be transparent and accountable not only to investors but to all stakeholders, including communities, suppliers, clients, employees, and governments. Therefore, extractive industries require effective sustainability accounting and reporting to transition and contribute to sustainable development.

SARS-CoV-2 Transmission in Livestock Industry and Agro-environment
The outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a public health emergency that turns the year 2020–2021 into annus horribilis for millions of people across international boundaries. The interspecies transmission of this zoonotic virus and mutated variants are aided by exposure dynamics of infected aerosols, fomites and intermediate reservoirs. The spike in the first, second and third waves of coronavirus confirms that herd immunity is not yet reached and everyone including livestock is still vulnerable to the infection. Of serious concern are the communitarian nature of agrarians in the livestock sector, aerogenous spread of the virus and attendant cytocidal effect in permissive cells following activation of pathogen recognition receptors, replication cycles, virulent mutations, seasonal spike in infection rates, flurry of reinfections and excess mortalities that can affect animal welfare and food security. As the capacity to either resist or be susceptible to infection is influenced by numerous factors, identifying coronavirus-associated variants and correlating exposure dynamics with viral aerosols, spirometry indices, comorbidities, susceptible blood types, cellular miRNA binding sites and multisystem inflammatory syndrome remains a challenge where the lethal zoonotic infections are prevalent in the livestock industry, being the hub of dairy, fur, meat and egg production. This entry provides insights into the complexity of the disease burden and recommends precision smart-farming models for upscaling biosecurity measures and adoption of digitalised technologies (robotic drones) powered by multiparametric sensors and radio modem systems for real-time tracking of infectious strains in the agro-environment and managing the transition into the new-normal realities in the livestock industry.

Applications of Polysaccharide Stalks in Didymosphenia geminata Diatom
Didymosphenia geminata is a species of freshwater diatom that is known as invasive and is propagating quickly around the world. The polysaccharide-based stalks of D. geminata enable versatile potential applications and use as a biopolymer, in drug delivery and wound healing, and as biocompatible scaffolding in cell adhesion and proliferation. Furthermore, the polysaccharide nature of stalks and their metal-adsorption capacity allow them to have excellent wastewater remediation potential.

Biological Influence of Aerosol Nutrients
The aerosol contains major ions, heavy metals, and organic matters that are important external nutrients in upper oceans and potentially influence marine microbes and biogeochemical cycles. Therefore, the role of atmospheric deposition to oceans has received growing attention.

Green Hydrogen Economy in Southern Africa
Green hydrogen energy is significant in decarbonizing the entire hydrogen value chain network from its generation to the end-user sectors. It can help achieve the UN Sustainable Development Goals (SDGs), especially the UNSDG 7, and regional sustainability. Further, the public sector (especially governments) are recognized to have a pivotal role in hydrogen energy deployment because it can enhance or drive the transition from a fossil fuel-based economy to a green economy, especially if the hydrogen energy ploicies are clearly articulated or translated into hydrogen energy statute in each Southern African Development Communities (SADC) country. To ensure that communities and SADC nations appreciate the hydrogen energy economy, there is need to also communicate the benefits that come with green hydrogen, alongside the global pursuit to reduce GHG emissions that cause climate change.
