In the context of the Sustainable Development Goals (SDGs), which strive to ensure comprehensive access to fundamental water, sanitation, and hygiene (WASH) services, it is extremely imperative to prioritize communities in need and still disadvantaged. Moreover, tackling the worldwide sanitation crisis entails advancing the development of productive and sustainable sanitation systems and infrastructure. Sanitation planning is a multidimensional exercise encompassing multiple dimensions, stakeholders, and strategies, typically with conflicting objectives.

Civil Engineering Department, University Department, Rajasthan Technical University, Kota, Rajasthan, 324010, India.
The current study investigates the relationship between urbanization, solid waste generation, and environmental changes in Kota city from 2000 to 2023. The study employs Google Earth Engine (GEE) to analyze land use and land cover (LULC) classification, normalized difference vegetation index (NDVI), normalized difference modified water index (NDMWI), normalized difference built-up index (NDBI), land surface temperature (LST), and predict future LULC changes up to 2043. The results show that the built-up area increased by 122.

School of Medicine, Institute of Health Science, Jigjiga University, Jigjiga, Ethiopia.
Background: One of the tropical illnesses that is often overlooked is soil-transmitted helminths, or STHs. In tropical and subtropical nations, where poor sanitation and contaminated water sources are common, they mostly impact the most vulnerable populations.
Objective: The aim of this study was to ascertain the prevalence of STHs and related risk factors among the people living in Jigjiga town, Somali region, Eastern Ethiopia.
Mechanisms for removing phosphorus species through sequential coagulation using inorganic coagulants and organic polymers.

Norwegian University of Life Sciences, Department of Building and Environmental Technology, P.O. Box 5003, 1430 Ås, Norway.
The need for stringent phosphorus removal from domestic wastewater is increasing to mitigate eutrophication, while efficient phosphate reuse is critical due to the global phosphate crisis. Combining aluminum sulfate (ALS) with high molecular weight organic polymers achieved 95-99% removal of particles, turbidity, and phosphates, reducing ALS usage by 40%. We propose mechanisms to explain the enhanced treatment efficiency.

Nowadays, performance studies on the amperometric total residual oxidant (TRO) sensor are only in the bench test stage and have not been conducted under specific maritime conditions with Ballast Water Management System (BWMS). In this study, the application of the amperometric TRO sensor in land-based biological efficacy (BE) testing, operation and maintenance (O&M) testing, as well as shipboard (SB) testing, was explored by comparing with the existing di-phenylene-diamine (DPD) TRO sensor. The results showed that the average TRO measurement deviation between the amperometric sensor and the DPD sensor was within ±10% in valid BE test cycles and the O&M testing exceeding 47 operating hours.
