Aquaculture uses large volumes of water, which is generally discharged without treatment, possibly causing scarcity and contamination. A sustainable aquaculture option is biofloc technology (BFT), which recycles food residues and toxic organic and inorganic compounds from the system through microorganisms, avoiding excessive use of water and serving as natural food for cultured aquatic organisms. The aim of this study was to identify the main factors that limit a Mexican aquaculture producer from adopting biofloc technology in their aquaculture production units (APUs). Strengths and weaknesses were methodologically analyzed through 248 questionnaires, applied to fish farmers in 16 states of the country with a mixed approach (quantitative and qualitative). Findings reveal that the main obstacles in the use of BFT are due to the following: low academic level, limited administrative capacity, scarce technological equipment in facilities, diversified productive activity, and obsolete regulations. Other factors that promote the adoption of BTFs for aquaculturists are production experience, favorable weather conditions, and abundant availability of water and energy. In conclusion, the use of BTF is a sustainable option for APUs despite the limiting factors identified in this research which slow down the growth of the sector. It is advisable to study Mexican producers with BFT, in order to spread their benefits to other APUs, and further evaluate the productivity of the aquaculture sector. This study considers production aspects, and also sustainable use of its resources, specifically, surface, energy, water, and food.

Adjustment of the Standardized Precipitation Index (SPI) for the Evaluation of Drought in the Arroyo Pechelin Basin, Colombia, under Zero Monthly Precipitation Conditions

Luis Jose Cerpa Reyes, Humberto avila Rangel, Luis Carlos Sandoval Herazo

Summary: The evaluation of meteorological drought is crucial for water resource management. The Standardized Precipitation Index (SPI) is widely used for drought assessment, but it may produce inaccurate results when dealing with zero precipitation data. This study proposes a modification to the SPI, called SPI-C, which introduces a correction factor to better handle zero precipitation data.

Evaluation of the Removal of Organic Matter and Nutrients in the Co-Treatment of Fruit and Vegetable Waste Using a Bioreactor-Constructed Wetlands System

Francisco Orduna-Gaytan, Norma A. Vallejo-Cantu, Andrea Alvarado-Vallejo, Erik Samuel Rosas-Mendoza, Luis Carlos Sandoval-Herazo, Alejandro Alvarado-Lassman

Summary: This article presents the application of a novel system for the treatment of fruit and vegetable waste using the combination of treatment by the application of the liquid fraction to an anaerobic hydrolytic bioreactor and a constructed wetland. The experimental results showed that the combination of these two technologies effectively removed COD from the liquid fraction of the waste, demonstrating the efficient treatment of fruit and vegetable waste.

A Review of the Presence of SARS-CoV-2 in Wastewater: Transmission Risks in Mexico

Mayerlin Sandoval Herazo, Graciela Nani, Florentina Zurita, Carlos Nakase, Sergio Zamora, Luis Carlos Sandoval Herazo, Erick Arturo Betanzo-Torres

Summary: The presence of SARS-CoV-2 in wastewater in Mexico was studied, and a correlation was found between the percentage of treated wastewater and the number of COVID-19 positive cases. The study highlights the need to increase wastewater treatment coverage and emphasizes the potential of untreated wastewater as a bioindicator for virus presence. However, the wastewater treatment systems in Mexico are fragile and limited in coverage.

Natural Fibers: An Alternative for the Reinforcement of Expansive Soils

Carlos J. Medina-Martinez, Luis Carlos Sandoval-Herazo, Sergio A. Zamora-Castro, Rodrigo Vivar-Ocampo, David Reyes-Gonzalez

Summary: Soil reinforcement is a technique used by geotechnical engineers to improve the shear strength and bearing capacity of soils. The incorporation of fibers into the soil matrix has gained attention as a low-cost and environmentally friendly alternative. This study provides a bibliographic review on seven natural fibers commonly used to enhance the mechanical behavior of expansive clay soils, concluding that the addition of natural fibers often increases soil's resistance to cutting.

Carbon Pool in Mexican Wetland Soils: Importance of the Environmental Service

Sergio Zamora, Irma Zitacuaro-Contreras, Erick Arturo Betanzo-Torres, Luis Carlos Sandoval Herazo, Mayerlin Sandoval-Herazo, Monserrat Vidal-Alvarez, Jose Luis Marin-Muniz

Summary: Mexican wetlands, which are important carbon stores in tropical wetland soils, are not included in global Earth system models. This review focuses on studying the carbon pools and sequestration in different types of wetlands in Mexico. It is found that swamps sequester more carbon in the soil compared to other wetland types, but they are not given sufficient attention in Mexican protection laws compared to mangroves. The carbon pools detected in mangroves, marshes, and flooded grasslands are statistically similar. Systematic data on carbon dynamics in tropical wetlands is needed for their incorporation into global carbon budgets.

Treatment Wetlands in Mexico for Control of Wastewater Contaminants: A Review of Experiences during the Last Twenty-Two Years

Summary: Constructed or treatment wetlands are a sustainable option for wastewater treatment. This study reviewed and analyzed the use of wetlands in Mexico, including types, sizes, pollutant removal efficiency, and plant species used. Most wetlands in Mexico are subsurface flow type, with horizontal flow direction being the most common. Pollutant removal rates varied for different pollutants, with COD, BOD5, TN, and TP removal ranging from 50-90%, 60-90%, 30-90%, and 30-70% respectively. The most used vegetation in Mexican wetlands includes Typha, Cyperus, and ornamental flowering plants. The study suggests further implementation of wetlands in rural and urban regions with similar characteristics to Mexico.

Alex Jose Bracamonte, Vicente Mercado-Puche, Gilberto Martinez-Arguelles, Luis Fuentes Pumarejo, Albert R. R. Ortiz, Luis Carlos Sandoval Herazo

Summary: In this research, an experimental plan was developed to obtain specific concrete variables and serve as a reference for a numerical and computational model. The experimental work reproduced a specific gradation of concrete, while the computational model used finite elements to simulate the behavior of concrete. The results showed that the compressive stress was more sensitive than the modulus of elasticity to changes in mesh size.

Use of Sawdust Fibers for Soil Reinforcement: A Review

Carlos J. Medina-Martinez, Luis Carlos Sandoval Herazo, Sergio A. Zamora-Castro, Rodrigo Vivar-Ocampo, David Reyes-Gonzalez

Summary: A common problem in geotechnics is the inadequate physical-mechanical properties of soils for construction work. Traditional methods of improvement often involve using binders such as cement and lime. However, due to climate change and the need for sustainability, researchers are now exploring the use of recycled and waste materials for soil reinforcement. Natural fibers, such as sawdust, have been found to enhance the shearing strength and bearing capacity of soils by generating high friction between the fibers and the soil matrix. This concept is inspired by the natural phenomenon of grass and plants stabilizing slopes.

Summary: Despite occupying a small area, natural wetland ecosystems play a crucial role in soil formation, food supply, climate regulation, and carbon sequestration. However, they are facing numerous incident factors such as agriculture, urbanization, and aquaculture, which lead to the loss of wetlands and reduction in carbon sequestration. Mangroves, lagoons, and marine waters are the most affected types of wetlands.
