The negative effects of climate change have burdened humanity with the necessity of decarbonization by moving to clean and renewable sources of energy generation. While energy demand varies across the sectors, fisheries, including fishing and aquaculture, are among the most energy intensive processes in the food production industry. The synergistic opportunities for co-located aquaculture and renewable energy can thus provide a multifunctional use of space and resources, creating opportunities to meet the identified energy demands of a variety of aquaculture operations. This study has investigated a sustainable energy model for a small-scale shrimp farm in western Taiwan with synergies for the dual use of the water area for solar photovoltaic electricity generation and aquaculture. Based on the simulation results and SWOT analysis, recommendations have been made for the design and operation of a solar-powered aeration system for shrimp farms. The average monthly energy production of 32 MWh is attainable at the estimated canopy space on a carport by installing 896 solar modules on the proposed site, fully covering the power demand of the shrimp farm. These findings have significance for encouraging effective practices in deploying solar techniques in aquaculture and making them replicable in global settings. © 2023 by the authors.

Saturated soil hydraulic conductivity (KSat) is a key soil attribute that affects hydrological processes in the soil surface layer. It is well known that KSat is difficult to be obtained in the field, requires time and expensive equipment, skilled labor and, due to its variability, requires many samples and can hardly be extrapolated. Artificial neural networks (ANNs) are powerful no-linear mathematical models to estimate KSat from different soil hydro-physical and environmental input variables as well as by using dimensionless variables generated by database resizing techniques from principal component analyses (PCA). The present study aimed to construct artificial neural network models for predicting KSat using soil attributes and different land uses as input variables at a watershed scale. The study was carried out in the Ellert Creek watershed of about 0.7 km2, Brazil, in which an experimental grid consisted of 178 sampling points was established. Data of soil bulk density, total porosity, microporosity, macroporosity, soil organic carbon content, sand, silt and clay, and KSat were determined at each point in the 0-20 cm layer. A land-use map was derived from satellite images and used to identify the land use around each soil sampling point. PCA was applied to the original data set and selected PCs were used as input variables for ANN modeling. Two PCs were selected and the results suggest that their inclusion as input parameters, both or individually, combined with the original data, increased the performance of the analyzed ANN models, when compared to similar models with only original data and without PCs. The use of ANN models showed that the variation of KSat in the ECW watershed is not only associated to soil hydrological and environment covariates, but also to PCs which are orthogonal linear recombinations that resume the main sources of variation of the original data sets. © 2023, The Authors.

This study examines a scenario combining a prolonged solar minimum, like the historical Maunder Minimum, with the increased CO2 emissions characteristic of the industrial era. Two scenarios were developed in NCAR/CESM 2.0 implemented at LAMMOC/UFF to create simulations from 1850 to 2000, it contrasts differing radiative forcings from 1950 onward—one reflecting actual observed changes, including rising CO2 levels, and the other simulating a decrease in solar output like that during the Maunder Minimum but with continued CO2 growth. The results were validated against ERA5 data and 20th-century reanalysis. By calculating meridional averages at 30-degree latitude intervals, distinct regional impacts of the Maunder Minimum were identified. Notably the simulated Maunder Minimum reduced global warming by and even mitigated 70 % in HS in the last decade of the 20th century. However, this attenuation was lower in the HN, especially in the 30–60N region where no attenuation was observed.

The study assessed the physicochemical and biological properties of selected groundwater sources in the Southeastern part of the Western Region, to assess the impact on water quality and health risk. The Piper Trilinear plot was used to categorize the water samples into water types based on the dominant anion and cation concentrations. Statistical analysis (One way ANOVA and two sample t-test) was used to determine the sources of variation in the data at 95% confidence interval. The water Quality Index (WQI) and Hazard Quotient (HQ) were used to estimate the water quality and health risk respectively. TDS and turbidity were above the acceptable WHO guidelines in 16.7% of the samples with a mildly acidic pH in 83.3% of the water samples. Also, 91.7% of the water samples were contaminated with total coliform (TC) and 25% with e-coli. Generally, the groundwater samples were dominated by Ca 2+ and HCO 3- ion water types. The variations between parameters were found not significant for all the parameters (p>0.05). water samples in the North are of good quality with a mean WQI of 96, but of poor quality in the South with a mean WQI of 144.6. HQ values for all the samples were less than 0.1, suggesting less harmful impacts of the heavy metal concentrations on human health. Overall, the results showed the presence of heavy metals in the groundwater sources sampled, however in quantities with low health risks either through oral or dermal channels. Groundwater within the communities is good for domestic purposes but needs treatment for drinking. To improve upon the study, it is recommended that further studies consider a higher number of samples and include other accessible groundwater stations where possible.

Soil physical quality (SPQ) is related to its conservation and degradation status. Among the indicators of SPQ, the S-index stands out, which is sensitive to different land uses and management practices adopted and capable of identifying structural changes with reference value ranges related to SPQ. These ranges are not suitable for various edaphoclimatic conditions, including the Santa Rita watershed (SRW), municipality of Pelotas, in southern Rio Grande do Sul, Brazil. The S-index is an excellent indicator and allows the mapping of physical vulnerability when considering the spatial uncertainties of the attribute. The general objective of this study is to evaluate whether the proposed S-index reference values by Dexter (2004) are suitable for soil boundary conditions, to define new critical S-index limits based on macroporosity, as well as to characterize the spatial distribution of the S-index and map critical zones of SPQ in the SRW. It was possible to identify a limiting S-index value of 0.039 for the edaphoclimatic conditions of the SRW. Through geostatistical techniques, it was possible to map physical vulnerability from the critical soil limit, thus identifying areas that require remediation. The limiting value proposed by Dexter was able to represent the spatial pattern of physical vulnerability in the SRW. The S-index proved to be an excellent tool for supporting decisions regarding the use, management, and conservation of soil physical quality and the environment. © 2023, The Authors.

Standard notions of an “Earthlike” planet rely solely on physical and material properties, like planetary mass, radius, and surface temperature. Here, we introduce a novel, relational perspective on what defines “Earthlikeness.” In our process-based framework, rocky planets are local pockets of free energy that have the potential to drive the emergence of dynamically persistent systems that coevolve with one another. Examples of dynamically persistent planetary phenomena include magnetic dynamos, mantle convection, tectonic regimes, deep volatile cycles, global climate feedbacks, biogeochemical cycles, and the biosphere. When two or more processes couple to one another such that they gain causal efficacy over one another's persistence, some degree of planetary-scale homeostasis may emerge. In astrobiology, Earthlike exoplanets are often considered to be priority targets for the search for life elsewhere. We suggest that a process-based framework for Earthlikeness has the potential to widen our search space and inspire novel planetary-scale biosignatures, or “Gaiasignatures,” that may be essential for detecting exoplanetary biospheres. Additionally, a process-based view of life can influence the development of agnostic biosignatures at all scales. In contrast to the dominant scientific perspective, which has tended to engender a materialistic worldview, relational ontologies may contribute to our scientific understanding of Earth as a network of dynamically persistent systems, humanity as an integral part of nature, and the search for life in the universe. A process-based framework may offer a better gauge of a planetary body's degree of “Earthlikeness” than physical or material considerations The search for life on exoplanets may require looking for “Gaiasignatures”—signs of a biosphere coupling with its geosphere in a dynamically persistent fashion By virtue of contrasting with dominant scientific worldviews, the ontology of relationality intrinsic to a process-bas

The aim of this paper is to compare the ability of two numerical models to simulate two-dimensional dam-break flows. Dam-break modelling is important in reducing the high-risk of dam failure by determining the water flow movement and its effect on buildings downstream. In this study, the Taylor Galerkin and Forward Time Central Space method is presented to simulate 2-D dam-break flow. The Hansen filter is applied to both methods to reduce numerical instability oscillations in the model. The filters were used for each time step at each computing point. The model is verified by comparing the result simulation with numerical results from previous studies. The result show that Taylor Galerkin numerical scheme with Hansen filter is successful to simulate the problem of 2-D dam-break. Also, the Taylor Galerkin model has better results than the FTCS model. Studies like this are needed for mitigation efforts in the event of dam failure.
