Improperly discarded cigarette butts are a substantial environmental problem. This study explored factors influencing cigarette butt discarding behavior on a public beach on Jekyll Island, Georgia, USA. A mixed-mode design utilized quantitative and qualitative data to study improper cigarette butt disposal. We surveyed smokers regarding their place attachment, environmental attitudes, environmental awareness, and habit as predictors of improper cigarette butt disposal. Environmental attitudes, environmental awareness, and habits were significant predictors of improper cigarette butt disposal behavior. A qualitative inquiry further explored the phenomenon of cigarette butt disposal from the smokers’ perspectives. Interviews illustrated that “improper disposers” experienced themes involving uncertainty that cigarette butts are litter, a lack of knowledge, problems with cigarette butt receptacles currently in place, the requirement of a conscious choice about how and where to discard a butt, and statements that contradicted the behavior observed. Themes that emerged from interviews with “proper disposers” included cigarette butts are clearly litter, awareness of social constructs that disapprove of smokers and their behavior, awareness of the cumulative effects of cigarette butts on the beach, minimal obstacles to discarding properly, and feelings of personal responsibility. Implications of the study results are discussed.

The human use of plant resources and land to face increasing population needs in Africa to the regression or even the disappearance of some useful multi-purpose species such as Diospyros mespiliformis Hochst. Ex A. Rich. Increasing climatic variability is an additional threat for these species. The present study aims to identify the areas that are potentially favorable to D. mespiliformis conservation or regeneration in Niger and to analyze the impact of the current climate change. Thus to assess the D. mespiliformis distribution areas, the geographic coordinates of D. mespiliformis, the bioclimatic data, the soil and vegetation cover were collected and used to modeling based on the principle of maximum entropy (MaxEnt). The soil cover, annual cumulated precipitations and the average temperature are the most determining variables. This study also shows that the ecological niche of D. mespiliformis is located in the Central and Eastern bioclimates, within which almost 3% of the surface is very favorable under the current climate conditions and may reach 3. 94 % under 2050 ones after. These results indicate that the climate change expected in Niger is expected to be more favorable to the studied species than the current climate conditions. This represents an opportunity for its domestication.

The paucity of information on the number of accessible sanitation facilities in secondary schools in developing countries has hindered efforts in attaining sustainable development in this area. Therefore, this study was designed to bridge that gap. The cross-sectional study utilized a 4-stage sampling technique to select 386 students from schools in Badagry, Lagos. Pre-tested questionnaire and observational checklists were used to obtain data. Data were analyzed using descriptive statistics and logistic regression at 5% level of significance. Respondents’ mean age was 15.8±1.5 years and 55.2% were female. On-site observation revealed that all the schools had improved sanitation facilities, while 37% of the available toilet compartments were inaccessible to the students. Majority (85%) of the facilities provided limited service, while 15% provided basic service. The student to toilet ratio for the public school girls and boys were 3191:1 and 642:1 respectively, while the private school had a ratio of 257:1 and 289:1 for girls and boys respectively. Some of the sanitation practices observed in the schools were open defecation (35.4%), toilet avoidance (21%), and prolonged urine and feacal retention (57.4%). Students from the public school were about 3 times more likely to practice open defecation (OR=2.87; CI=1.160-7.095). Also, male students were more likely to practice open defecation (OR=1.72; CI=1.125-2.615). All the schools did not meet the school sanitation standard of 1 toilet to 30 boys/girls set by the Federal Government of Nigeria. Sustainable sanitation-interventions and maintenance schemes are required to safeguard the health of the students and the community at large.

The unsaturated zone of floodplain wetlands in the White Volta River basin provides an inextricable link between basin hydrology and the sustenance of plant growth. The HYDRUS-1D model was used to derive water budgets and to estimate fluxes to understand the hydrological complexities of these wetland systems. The model result indicates Spatio-temporal variation in the volume of vertical fluxes. In 2005, the estimate for average simulated flux was 0.29 cm/month in June and 1.23 cm/month in July. Consequently, the hydraulic head increased from 138.94 m to 139.30 m for the period from June to July 2005. For all sample sites, the increase in hydraulic head occurs within July and October, coinciding with high surface water fluxes. From the calculated water balance, the average monthly estimate of bottom flux was 0.01 cm/month for 2004 and 1.1 cm/month for 2005. The flow through the unsaturated zone and discharging into the subsurface water system has a high dependency on both the soil structure and the volume of water infiltrating through the surface; the highest discharge is within the period of highest water input.

The study of community tourism development based on green economy model is the focus of this paper. The research is implemented in Viet Hai - a commune of Cat Hai island district, Hai Phong city, Vietnam. In order to evaluate, select and develop this model in the locality, a number of research methods have been applied such as: Method of seminars, expert consult, group system of sampling methods, fertilizer analyzing laboratories and methods of interviewing and collecting socio-economic data. The research outcome is given that, the community tourism based on green economy is a type of economic model that contributes not only on the local socio-economic development, but also surmounting the seasonal tourism situation, and maximizing the region's potential and strengths. The model chosen was the communitys based tourism model, with the participation of 1/3 of households in Viet Hai commune. The model has a management board with applicable rules and regulations to objects such as households, tourism operators and Viet Hai visitors. The model has been oriented towards exploiting the landscape values associated with environmental protection programs, especially towards the point-based community tourism model of Cat Ba district – which say “no” to single-use plastic products. This tourism model has created the tourism products that are different from the existing models in Cat Ba (Hai Phong), creating channels to link with tourists to attract more visitors to Viet Hai increasingly to the year.

γ-Al2O3 supported Cu, Cu-Zn and Cu-Ni-Fe-Zn oxide catalysts were prepared using leachate transition metal nitrate and sulfate aqueous solutions from commercial spent catalysts. A bench-scale rig was used to investigate the combustion activity of these catalysts toward methane or ethane in the air stream (1000 ppmv) at a space velocity of 20,000 h-1. The Cu-Ni-Fe-Zn oxides/γ-Al2O3 catalyst proved to be the most active catalyst for the combustion of methane in the temperature range 290-575°C and of ethane in the lower temperature range of 275-525oC as compared to Cu and Cu-Zn oxide loaded catalysts. X-ray powder diffractograms indicated that the metal oxide species were highly dispersed or amorphous on the alumina surface in all the catalysts except for the detection of a minority phase of monoclinic CuO on the Cu-containing mono-metallic catalysts. The co-existence of ZnO in the CuO catalysts suppresses the activity of the copper oxide species and, therefore, the conversion of methane or ethane was reduced. The present research endeavor provides proof-of-concept that relatively inexpensive metal oxide-based heterogeneous catalysts for VOCs abatement can be recovered from spent catalysts. Hence, environmental and health threats of improper handling of VOCs or spent catalysts may be alleviated.

It was sought, in this research, to evaluate the effects of fertilizer solutions on water retention by hydrogel as well as if the application methods and fertilizers affect water retention when the hydrogel is added to the soil. In laboratory works (experiment 1), the completely randomized design was used taking into account four treatments: distilled water; Urea (UR – 2.0 g L-1 ) and Magnesium Sulfate + Monoammonium Phosphate (MS + MAP – 2.0 g L-1  each). Regarding the experiment 2, considering soil columns, a 2x3x2 factorial was used, corresponding to two hydrogel application methods: dry and mixed to the soil or diluted in water and concentrated in the center of the column; three fertilizer solutions: distilled water, UR (2.0 g L-1 ) and MS + MAP (2.0 g L-1  each) with two cycles and three repetitions. An additional witness (hydrogel free) was also added. Total water volume absorbed by hydrogel, volume stored in the soil after each cycle, pH and electrical conductivity (EC) of leached solutions were all analyzed. The MS solution was the one who impacted the most the water absorption by the hydrogel, principally when the hydrogel was not present in the soil. The pH and EC of leached solutions evidenced the fertilizer solutions salinity.
