Abstract Adoption of certified and improved high-yielding varieties is a critical strategy for farmers in developing nations to increase agricultural productivity and living circumstances. The goal of this research was to investigate the factors that influence the adoption of improved cotton varieties by small-scale farmers in Tando Allahyar area of Sindh, Pakistan. In this study, Tando Allahyar area was selected, which is the main area of cotton cultivation. With the help of specially designed questionnaires, Bt cotton and non-Bt cotton data were collected from Better cotton registered farmers through personal interviews. Data were collected by simple random sampling. Descriptive and probabilistic regression models were used for data analysis. The empirical results showed that year of age (P≤ 0.000), House hold size (P≤ 0.092), farm machinery ownership (P≤ 0.000), distance to market (P≤0.005), access to market information (P≤0.003) and ground water quality (P≤ 0.000) had significantly positive influence on adoption of Bt cotton and non-Bt cotton verities, while age (P≤ 0.053) had significantly negative effect, while farming experience (P ≤-0.000), had significantly negative effect.

In this work, the assessment of surface and ground water quality of Palladam Taluk, Tiruppur, district, Tamil Nadu, India were carried out using Geographical Information System (GIS) and Modified National Sanitation Foundation -Water Quality Index (MNSF-WQI). Four samples from surface and twenty seven samples from ground water sources were taken from Palladam Taluk, Tiruppur District. In the current study, the surface and ground water samples were analysed for temperature, pH, dissolved oxygen (DO), electrical conductivity (EC), biological oxygen demand (BOD), turbidity, total dissolved solids (TDS), total hardness (TH), faecal coliforms (FC), total phosphate (TP), total nitrate (TN), chlorides (Cl-), sodium (Na+) and fluoride (F-) ions to investigate the suitability of surface and ground water for drinking and agricultural purposes through Geographic information system (GIS) and modified national sanitation foundation water quality index (MNSF-WQI) technique. The concentrations of TH, TDS, Cl- and Na+ were observed to be above the desirable limit of World Health Organization (WHO) guidelines and Bureau of Indian Standards (BIS). whereas F-, BOD, DO, EC, TP, TN, FC and temperature were within the acceptable limits. The GIS-based WQI map analysis indicated that 45% of the study area having good water quality index and the remaining area showed medium quality water. Dyeing and textile industries in the study area are responsible for deteriorating the quality to medium quality of water which was not appropriate for direct utilization and needed prior treatment. There is no detailed report on assessment of the surface and ground water quality of Palladam Taluk in Tamil Nadu using GIS and MNSF-WQI techniques.

This study shows the effect s of solid waste dumpsite on ground water quality in Farin-gida, Kaduna State Nigeria. Water samples were collected from six (6) different wells in three(3) strategic areas that have major dumpsites in Farin-gida. These samples were collected in November from both bore holes and hand dug wells within (0-50 meters) to the dumpsite. The following physico-chemical properties of well water was tested for, in the laboratory thus; Total Dissolve Solid, Total Alkalinity, Fluoride, PH, Turbidity and Electrical Conductivity. The results obtained as shown in table 1,2 and 3 respectively indicate that all the wells have varying levels of physico-chemical concentration that is different from the standard as recommended by World Health Organization (WHO) and Nigeria Standard for Drinking Water Quality (NSDWQ), which implies that the water from the study areas are not safe for drinking. Hence, should be treated.

Abstract This study was conducted to investigate the effects of municipal solid waste (MSW) used as landfilling on the ground water quality and health effects on the community. The study was carried out in Mardan, Khyber Pakhtunkhwa province- Pakistan. To assess the impacts, 13 ground water samples were collected from Solid Waste Dumping Sites (SWDS) and 13 from Safe Sites (SS). Ground water was analyzed for pH, Turbidity, Electrical Conductivity (EC), Total Hardness (TH), Cl−, Ca+ 2, K+ 1, NO− 2, NO− 3, SO4 − 2; heavy metals such as Pb, Cr, Mn, Cu, Ni, Zn, Cd, Fe; biological parameter such as Total Coliform. Waste sample collected from SWDS showed that food and garden waste were present highest percentage by weight (30.5%) followed by fines (17.3%). The two groups (SWDS and SS) differ significantly for the parameters like EC, TH, COD, Na, Ca, NO3− and SO4 − 2 Ni and TC. Samples collected from SWDS (84%) were found contaminated with TC ranged 2–22. It was analyzed that pH, EC, TDS, COD, TH, NO3−, SO4 − 2, NO2−, Ca+ 2, Na+, TC, Cr, Ni, Zn, Cd and TC were more in the sample collected from 70–130 feet than 140–200 feet. TC found in 70–80 feet depth was significantly different from rest of the groups. Similarly, significant difference regarding different parameters for various depths was found for K+ 1, Ca+ 2, NO2−, Pb, Cu and Fe. The results of the questionnaire survey revealed negative correlation between the diseases and distance from the landfilling sites and significant correlation was observed for typhoid, cholera skin allergies and gastro enteritis. The study confirmed that using MSW as a fill material has contaminated the ground water quality and leveling of land through MSW is not safe. Deep drilling is recommended for extraction of ground water in the contaminated area to minimize the associated health risks.

The quality of coastal ground water on small islands has characteristics that are influenced by environmental and area factors. Yeben Island is a small island with an area of 0.57 km2 with priority coastal and marine tourism areas in the islands of Raja Ampat. This study aims to (1) analyze levels of ground water quality parameters and (2) analyze water samples against water quality standards. Groundwater samples taken as many as 4 samples from the study location. The location of water samples is in the morphology of the coastal plain. The analysis of each physical and chemical parameter of each groundwater sample is carried out by comparing the value of drinking water quality standards. The results are presented in a comparison table of quality standards and a graph of scaled values.Based on the results, the laboratory shows that it exceeds the quality standard of physical elements and chemical elements including fluoride, hardness, sulfate and organic substances. In general, the quality of water is poor. Poor ground water quality occurs due to the influence of sea water intrusion.

Aims: To determine the effects of salt harvesting on ground water quality in Gongoni ward, Kilifi County. Study Design: The study design was purposive where sampling points were deliberately chosen. Place and Duration of Study: The study was carried out in Gongoni ward and its environs in Kilifi County from May 2015 to July 2015. Methodology: Sixteen sampling points were selected within the study area and sampling was done twice between May and July 2015. The water samples collected were analyzed for sodium (Na+), Chlorides (Cl-), Fluorides, (F-) Calcium (Ca2+), alkalinity, acidity (pH), E. coli, Total Dissolved Solids (TDS) and Salinity as NaCl in the Government Chemist laboratories in Mombasa. The collected data was analyzed using SPSS and Microsoft Office Excel. Results: The ground water sources in Gongoni ward registered high levels of key parameters (TDS, Salinity, Chloride, and Sodium) than the adjacent areas of Mambrui, Ngomeni and selected secondary data from Mombasa County wells where no salt harvesting occurs. Gongoni water sources had a mean TDS of 1969.00mg/L and the adjacent area shad TDS of 1050.00 mg/L. The level of E. coli and total coliform were above the Kenyan and WHO permissible limit of 0 MPN/100ml for treated water and 10 MPN/100mls for untreated water. Conclusion: Despite the elevated concentration levels of chemical parameters from Gongoni ward water sources, the differences are not statistically significant when compared to the adjacent areas of Mambrui and Ngomeni. Recommendations: The water from sources with high levels of TDS and salinity should be pre-treated to make the water more suitable for human use. Those with high coliform and E. coli bacteria should be regularly treated using the appropriate disinfection methods. It is recommended that all projects on salt harvesting should be subjected to an Environmental and Social Impact Assessment (ESIA) before implementation as provided by the Kenya Environmental Management and Coordination Act of 1999.
