Sustainability in Brazil’s Beef Industry
Since the dawn of Brazilian trade, extensive cattle farming has predominated. Brazil’s extensive pasture-based system uses pasture plants adapted to climate and soil conditions with limited use of purchased inputs. Domestic and international stakeholders have prioritized sustainable agricultural development in Brazil’s beef sector to reduce deforestation and other natural-habitat conversions.

Geological Site Effects in Archaeoseismological Point of View
Earthquakes have and continue to, occur worldwide, though some places are affected more than others by earthquake-induced ground shaking and the same earthquake can cause more damage in one area than in nearby locations due to site-specific geological site conditions, also known as local site effects. Depending on the chronology of the earthquakes, various disciplines of seismology include instrumental and historical seismology, archaeoseismology, palaeoseismology and neotectonics, each focusing on using specific sources of information to evaluate recent or ancient earthquakes. Past earthquakes are investigated to expand the pre-instrumental and instrumental earthquake catalog and better evaluate a region’s seismic hazard. Archaeoseismology offers a way to achieve these goals because it links how ancient civilizations and their environment might have interacted and responded to past earthquake-induced ground motion and soil amplification. Hence, archaeoseismology explores pre-instrumental (past) earthquakes that might have affected sites of human occupation and their nearby settings, which have left their co-seismic marks in ancient manufactured constructions exhumed by archaeological excavations. However, archaeoseismological observations are often made on a limited epicentral area, poorly constrained dated earthquakes and occasionally on unclear evidence of earthquake damage. Archaeological excavations or field investigations often underestimate the critical role that an archaeological site’s ancient geological site conditions might have played in causing co-seismic structural damage to ancient anthropogenic structures. Nevertheless, the archaeological community might document and inaccurately diagnose structural damage by ancient earthquake shaking to structures and even estimate the size of past earthquakes giving little or no consideration to the role of geological site effects in addressing the causative earthquake.

Pectin-Based Material for Applications in Water Treatment
Climate change and water are inseparably connected. Extreme weather events cause water to become more scarce, polluted, and erratic than ever. Pectin is a biodegradable polymer, extractable from vegetables, and contains several hydroxyl and carboxyl groups that can easily interact with the contaminant ions. In addition, pectin-based materials can be prepared in different forms (films, hydrogels, or beads) and cross-linked with several agents to change their molecular structure. Consequently, the pectin-based adsorbents can be tuned to remove diverse pollutants such as divalent metals.

Olga Muter
Our studies on soil bioremediation, wastewater treatment and air biofiltration embrace a broad range of methodical approaches and target microorganisms. Application of biostimulation and bioaugmentation tools provide a great variety of biodegradation scenarios under contrast/seasonal/globally changing environmental conditions. Soil bioremediation: our studies showed a stimulating effect of the c

Sources of Microorganisms for Bioaugmentation
Bioremediation encompasses a broad range of environmental biotechnologies, which require multidisciplinary approaches through implementation of innovative tools to the natural biological processes occurring in soil, water, and air. The addition of microbial biomass (bacteria, fungi, and their secreted enzymes) to contaminated areas, i.e., the process of bioaugmentation, can be adapted to the green environment and can notably improve an area’s pollutant removal efficiency (RE), as well as reduce their removal time and costs.

Plant Ecological Treatment Technology for Livestock Wastewater
After antibiotics are used in livestock and poultry, on the one hand, selection pressure will be formed to make the intestinal microorganisms of livestock and poultry develop resistance, thus making livestock and poultry manure carry a large amount of antibiotic resistance gene (ARG); on the other hand, about 30-90% of antibiotics will be discharged into the environment with livestock and poultry manure, and the antibiotics entering the environment will not only cause chemical pollution, but most importantly, may induce antibiotic-resistant bacteria (ARB) and ARG in the environment generation in the environment. The sources of ARGs in livestock wastewater may be threefold: (1) livestock wastewater receives ARGs already present in livestock manure; (2) pollutants such as antibiotics and heavy metals in wastewater induce microorganisms to produce ARGs; and (3) proliferation of microbial host bacteria leads to proliferation of ARGs. Unlike traditional chemical pollutants, which exhibit unique environmental behaviors such as replicability, transmissibility, and environmental persistence due to their inherent biological properties, ARGs are promoted by mobile genetic elements such as plasmids, transposons, integrons, insertion sequence common regions, and complex integrons. These ARGs are transmitted between different microorganisms in environmental media through horizontal gene transfer (HGT) mechanisms and may enter the food chain and humans through direct or indirect routes, increasing human drug resistance and endangering human public health.

Water Mills
The reuse of built agricultural/industrial heritage has been a common practice worldwide. These structures represent excellent symbols of the great agricultural/industrial past. These agricultural/hydro-technologies also serve as monuments of socio-cultural identities, especially in rural areas and on small farms. One example of a successful application of agricultural technologies for small farms is the water mill. By harnessing the water energy, they were used for traditional flour and other goods production (e.g., olive oil) and works requiring energy, with the main role in the evolution of the traditional/cultural landscape. Water mills have been used to drive a mechanical process of milling, hammering, and rolling and are a portion of the agricultural, cultural, and industrial heritage.
