Community faecal sludge management strategy among urban slum people of Khulna city-Bangladesh
Abstract
Faecal sludge management (FSM) has conquered notable recognition by all authorities for its importance. Because it has large scale impacts on human-environment. This study was an initiation to explore the current situation and the prevalent practice of FSM among slums people of Khulna city-Bangladesh. Applying face-to-face interview technique household survey was conducted through a structured questionnaire, where 104 participants were purposively selected for taking interview. This study was carried out in slums area of Khulna city Bangladesh. The people of Khulna particularly slums people are not so aware of using sanitation properly. Findings of this study exerts that a very large portion of slums people here are having not enough knowledge about sanitation issues and Faecal Sludge Management. Off the 100% (92/82.5%) respondents of the study area have never taken any training on FSM. A large volume of people used to use community latrine, where lack of privacy, scarcity of water, absence of hand wash facilities and unsafe manual emptying are still the major problems. Until now a large number of toilets are directly connected to drain, and whereas 23 (22%) asserted that human excreta directly goes into open water i.e. (river and pond that so deplorable. The result elucidates that within (1 or 2 years) (75/72.12%) septic or other tanks didn’t get emptied whether (18/62.07%) were unfilled through unsafe manual process. In fine, it can be said that alongside arranging different awareness programme alternative small emptying devices like Vacutug must be arranged here with low cost for the disadvantaged. Therefore, a comprehensive detailed scientific study demands this sector for further designing any strategic plan.

Assessment of air quality and its health implications on Abuja campus residence, University of port Harcourt, Nigeria
Abstract
This study investigated the concentrations air pollutants in the air quality of the Abuja campus business area of the University of port Harcourt. Air pollutants and meteorological parameters were monitored on monthly basis for a period of six months (February to July 2017) using suitable calibrated air quality instrument. Daily 1-hour averaging of pollutants concentrations was carried out for a period of 8 hours. SO2 showed minimum mean concentration of 0.25ppm in April and maximum mean concentration of 0.63ppm in March; NO2 showed minimum mean concentrations of 0.13ppm in April and maximum mean concentration of 0.75ppm in March; CO showed minimum mean concentrations of 0.5ppm in April and maximum mean concentration of 2.25ppm in February; H2S showed minimum mean concentration of 0.25ppm in March and April and maximum mean concentration of 0.38ppm in February, May and July; mean concentrations of CH4 ranged from 21.25ppm (minimum) in May to 32.5ppm (maximum) in February; mean concentrations of NH3 ranged from 0.13ppm (minimum) in February to 1.163ppm (maximum) in July; also mean concentrations of SPM ranged from 62.65 µg/m3 (minimum) in July to 555.5 µg/m3 (maximum) in March; mean concentrations of PM10 range between 51.75 µg/m3 (minimum) in April and 428 µg/m3 (maximum) in March; mean concentrations of PM2.5 ranged between 24.13 µg/m3 in April (minimum) and 203.63 µg/m3 (maximum) in March. The study revealed that the air quality in the Business Area of Abuja Campus of the University of Port Harcourt is polluted and poses a major risk to human health. Long-time exposure may exacerbate cases of respiratory and cardiovascular problems among the exposed population.

A rapid technique for measuring oxidation-reduction potential for solid materials
Abstract
The present study proposes a rapid measurement technique of oxidation-reduction potential (ORP) of solid materials. With the conventional portable ORP meters, the proposed procedure includes a) grinding of solid and sieving to a homogeneous grain size, b) making slurry with di-ionized water at a definite solid-solution ratio, c) shaking and centrifuging of the slurry at some intervals until maximum ORP values obtained. The changes of ORP values by this rapid method were found clearly distinguishing between oxidized and fresh rock type.

Evaluation of daily pollutant standard index and air quality index in a university campus in Nigeria using PM10 and PM2.5 particulate matter
Abstract
A study on the evaluation of pollutant standard index and air quality index in Choba campus of the University of Port Harcourt, Nigeria based on particulate matter were assessed. Aeroqual-PM10/PM2.5 and CW-HAT200 particulate sampler instruments that measure particulate matter by a method of light scattering were used. Pollutant standard index and air quality index were computed using measure concentrations of PM10 and PM2.5 particulate matter. The study shows that a positive linear relationship exists between pollutant standard index and air quality index, the relationship is highly significant (p-values < 0.0001, R2 = 99.1 %). Statistical result indicates that PM2.5 constitutes 52.68% of the concentrations of PM10. PM2.5 fine particle was found to be the predominant particulate pollutant in the University Campus. Computed air quality index shows good air quality 17% of the days, moderate air quality 79% of the days and unhealthy air quality for sensitive groups 4% of the days. Sensitive groups on the campus may be experiencing coughing, shortness of breath sneezing, asthma attacks, coughing, reduced lung function and wheezing. The management of the university should communicate the air quality indices in this study to the students and public so that precautionary measures can be taken to reduce prolong exposure.
Key Words

Transparency helps in balancing the environment, society and economy: lessons from the world’s largest public works program
Abstract
Sustainable development depends on the complex set of interactions between the natural environment, the society we live and economic conditions. The relationship between humans and the environment is like 'one will give and other will take', during which equilibrium may get distracted. Economics leverages the growth potential of the society and society is influenced by the natural environment. To maintain the equilibrium between these three pillars of sustainable development there is a need to link them. Transparency during the execution of large-scale projects plays a pivotal role in achieving sustainable development and enables the balance between the environment, society, and economy. In recent times, the governments of many countries have adopted programs for improving the living standards, food security and improved nutrition, health, clean water and sanitation, education, and other aspects of sustainable development goals. This article reports the transparency methods that are implemented for MGNREGA project and articulates the role of transparency in linking between the three dimensions of sustainable development: environment, society, and economics. The paper emphasizes that the mechanism of transparency should reside in all sides of the triangle of sustainability.

Land cover and land use change detection by using remote sensing and GIS in Himchari National Park (HNP), Cox’s Bazar, Bangladesh
Abstract
Himchari National Park (HNP) is a protected area that has been degraded, fragmented and converted severely into various land uses. In this study, land use changes of HNP were assessed from 1977 to 2017 by using Landsat 8 OLI-TIRS, Landsat 5 TM and Landsat 2 MSS satellite imagery. The ArcGIS v10.4 and ERDAS Imagine v15 software were used to process satellite imageries and assessed quantitative data for land use change assessment of this study area. Maximum likelihood classification algorithm was used for the assessment of supervised land use classification. Spatial and temporal dynamics of land use/cover changes (1977-2017) were quantified using three Satellite/Landsat images, a supervised classification algorithm and the post classification change detection technique in GIS. Some negative changes of land uses were showed from 1997-2017; but land use changes pattern from 1997-2017 showed comparatively better changes than 1977-1997 time period. But overall land use changes from 1977-2017 showed Dense Forest (529.4 ha) tends to degraded; agriculture (20.1 ha), degraded land (232.4 ha), settlement (82 ha), light forest (192.6 ha) and water body (2.2 ha) were increased. For the next 20 years of land use/cover changes, it is predict that more than 27.59% dense forest (145.83ha) will be decreased; on the other hand, 20% agriculture (4.02 ha), 9.86% degraded land (35.49 ha), 20 % settlement (16.40ha), 12.17% l light forest (89.47 ha) and 20% water body (0.45 ha) will be increased in 2037. The overall supervised classification accuracy was found 88.64% for 2017, 85.19% for 1997, and 87.67% for 1977 with Kappa values of 0.812, 0.71, and 0.78 for 2017, 1997, and 1977 respectively and these were fairly satisfactory. The present study is suggested for the sustainable management, protection, conservation and proper utilization of the natural resources of HNP.

Evaluation of integrated nutrient management practices on growth, yield and economics of chilli
Abstract
Chilli is one of the most important energy rich vegetable-cum- spice crops in Bangladesh. An experiment was conducted at the Multi location Testing (MLT) sites (AEZ-03) at Chakloma and Goneshpur of Shibganj upazilla under Bogura district during two consecutive rabi season of 2015-16 to 2016-17 to investigate the response of chilli (Capsicum annum) to different nutrient management practices under farmer’s field condition. The experiment was laid out in randomized complete block design (RCBD) with six replications. Chilli var. Magura local variety was used as experimental crop. Five treatments viz. T1= Soil test based fertilizer dose for HYG (FRG 2012), T2= IPNS with 3 t ha-1 poultry manure, T3= IPNS with 5 t ha-1 cowdung, T4= Recommended fertilizer dose based on FRG 2012 for HYG and T5= Farmers practice. The highest chilli yield (14.44 t ha-1 at Chakloma & 14.95 t ha-1 at Goneshpur), gross return (TK. 587800 ha-1) and BCR (4.54) were found from T2 (IPNS with 3 t ha-1 poultry manure) which was statistically differed to other treatments whereas, the lowest yield (10.16 t ha-1 at Chakloma & 11.7 t ha-1 at Goneshpur, gross return (TK. 443400 ha-1) and BCR (3.93) were obtained from treatment T5 (Farmers practice). The Integrated plant nutrient management system produced better yield of chilli and showed significantly vary among the treatments. However, from results, it could be recommended that IPNS will be a promising technology for higher crop yields of chilli and profit as well as for the improvement of soil fertility & sustain soil productivity in Bogura region.
