Novel Techniques for Removal of Dyes from Wastewater: A Review

Priyanka Jangid — 2025-04-25

Dyes are extensively used to color products across various industries, including textiles, leather tanning, cosmetics, and pigments. The textile sector alone accounts for approximately 14% of India’s total industrial production, contributing around 4% to the nation’s GDP and generating about 27% of its total foreign exchange earnings. However, the discharge of effluents from these industries poses significant environmental and health risks. In India, textile industries consume over 100 liters of water to process just 1 kg of textiles, which has led to the contamination of surface and groundwater resources in several regions. To mitigate the detrimental impact of dyeladen wastewater on human health and ecosystems, effective treatment is essential before effluents are discharged into water bodies. Consequently, the removal of dyes from wastewater has gained considerable attention in recent years due to the harmful, often carcinogenic, effects of untreated textile effluents. Dye removal from wastewater can be accomplished using a range of physicochemical or biological methods. This paper reviews existing literature on the importance of remediation technologies aimed at efficiently removing textile dyes from industrial effluents, with a focus on improving fragile ecosystems worldwide.

Nisha Saini — 2025-04-25

Nanotechnology has the potential for addressing current issues related to agriculture and is an innovative technique for increasing the production of crops. A wide variety of materials, such as metal, metallic oxides, nonmetals, ceramics, semiconductors, polymeric structures, lipid-based nanostructures, carbon-based nanostructures and quantum dots, are included in nanoparticles, which range in size from 1 to 100 na-nometers. Their use asherbicides, pesticides, insecticides, and nano fertilizers has been made easier by their large surface area, strong reactivity, and nanoscale size. Furthermore, nanoparticles can be engineered to function as carriers of genetic material, molecular probes, and agrichemicals as well as biosensors in the diagnosis of plant diseases. The use of nanotechnology in plant pathology has increased dramatically in the last ten years, with nanomaterials being essential for molecular tools for study, disease management, and detection. Utilizing metallic and metallic oxide nanoparticles as antibacterial agents and nano fertilizers to inhibit infections and improve plant health has received a lot of attention. Much research has also been done on their potential as sensor technology for accurate and quick diagnosis of plant diseases. The field of nanotechnology provides promising alternatives as the need for environmentally friendly agricultural methods grows globally in the face of climate change issues. Nanoparticles have the potential to completely transform agricultural disease management techniques by reducing chemical inputs and facilitating the quick identification of pathogenic organisms, hence promoting sustainable as well as resilient food systems.

Impact Analysis of Microfinance on Women Empowerment: An Empirical Evidence

Khushboo Sogani — 2025-04-25

This study examines the impact of microfinance on women's empowerment in Rajasthan, emphasizing its role in their economic, social, and political engagement. The primary objective is to evaluate how Self-Help Groups (SHGs) contribute to improving women's access to financial resources, enhancing their decision-making abilities, and fostering socio-economic advancement. Additionally, the research seeks to analyze microfinance initiatives to determine their effectiveness in alleviating poverty, promoting gender equality, and enabling women to overcome systemic barriers. The study uses mixed methods between qualitative and quantitative methodologies. SHGs members from various rural and semi-urban locations in Rajasthan were nominated to participate in the structured interviews and surveys, which were then used to gather primary data. Secondary data, including eports and case studies, supplemented the analysis to contextualize findings within broader trends. Statistical tools were employed to measure the relationship between SHG participation and indicators of empowerment, such as income generation, access to education, healthcare decisions, and community involvement. The findings reveal that participation in SHGs significantly enhances women’s financial independence, improves household decision-making, and strengthens their confidence in public life. Microfinance serves as a catalyst for creating sustainable livelihoods, reducing dependency on exploitative lending practices, and fostering community solidarity. However, challenges such as limited literacy, lack of training, and socio-cultural constraints remain barriers to maximizing the benefits. The study emphasizes that sustaining the positive effects of microfinance on women's empowerment in Rajasthan requires well-designed policy measures, capacity-building initiatives, and ongoing support for Self-Help Groups (SHGs).These insights contribute to the growing evidence base on the transformative potential of microfinance in achieving inclusive development goals.

Impact of Climate Change on Water Resources: A Review

Nimisha Jain — 2025-04-25

Climate change is the increase in Earth’s mean temperature and the corresponding significant modifications to weather patterns. Climate and water are inextricably linked. Water gets more scarce, polluted, and unreliable as a result of severe weather conditions. Resources of water are projected to be impacted by climate change, which has an impact on precipitation quantity, variability, timing, form, and intensity. Rising global temperatures result in more water evaporating, which raises the amounts of water vapor in the atmosphere, leading to more frequent, intense, and violent rainstorms in the years to come. Temperature and precipitation variations are the primary ways of climate change that modify the hydrological cycles, which could exacerbate regional and worldwide water shortages. Therefore, the main cycle through which climate change occurs is weather and water, specifically the delicate balance between evaporation and precipitation. Water management techniques and the operation of current water infrastructure, such as irrigation, drainage, flood defenses, and hydropower, are all impacted by climate change. Current climate projections indicate that safeguarding the water will require controlling its effects, whether excessive or insufficient and taking the necessary steps to reduce the vulnerabilities of businesses and communities. The correlation between climate change and water resources is discussed in this review. Evaluating the availability of water resources in light of future national needs and the predicted effects of climate change and its variability is essential for long-term development on both a national and global scale. Consequently, it is clear that there are intricate connections between the climate, water, biophysical and socioeconomic systems. Therefore, human society, especially in Rajasthan is primarily concerned about the interaction between change of climate and water resources, particularly freshwater.
