For evaluation of Phytoremediation potential of Rosemary plant in contaminated soils with Cadmium and Zinc, Two Greenhouse pot culture experiments were conducted in Fars Education Center of Jahad-e-Agriculture- Aliabad kamin. Treatments included soil cadmium with six levels (0, 10, 20, 40, 80 and 160 ppm) and zinc with six levels (0, 25, 50, 100, 200 and 400 ppm). Each treatment was replicated three times. In this study, cadmium sulfate and zinc sulfate were used, for contaminate soil samples different amounts of salts dissolved in distilled water and sprayed on the soil. The results showed, with increasing cadmium and zinc concentrations in soil, cadmium and zinc concentration increased in root and shoots. The highest cadmium and zinc transfer factor was observed in treatment 80 and 25 ppm respectively. Maximum bio accumulation factor for cadmium and zinc obtained from 80 and 400 ppm respectively. Rosemary plant can fix the elements of cadmium and zinc and transfer it to the shoot.

This study is geared at investigating the environmental and health effect of waste management in Ogba/Egbema/Ndoni local government area of Rivers State. The target is, to study the environmental challenges, health challenges as well as economic challenges caused by improper waste management in Ogba/Egbema/Ndoni Local Government Area of Rivers State, Nigeria. Survey design is deemed appropriate for this study because it involves the gathering data on research issues as they were at the period of research. Random sampling technique was used to gather data. The sample size was made up of 400 male and female of different areas of the local government area. Mean and standard deviation was used to answer the research questions while hypotheses were tested using regression at 0.05 level of significance. The research revealed that the relationship between environmental and health effects of waste management in Ogba/Egbema/Ndoni local government area was moderate (r = -.560). The R-square value of 0.313 indicated roughly a contribution of 31% of waste management to their health. Therefore, the regression equation shows that shows an increase in poor waste management may lead to a concomitant decrease in the state of health in the area. The research then found out that improper waste management can have negative impacts on both the environment and public health. Results obtained also proved that as you move away from the dumpsite the impact is not as severely affected as those who are closer to the dumpsite. The government and municipalities should revise laws regarding the locations of dumpsites. These laws should include properly managed sites, which are well fenced in and away from human settlements.

The study intends to investigate the impact of solid waste disposal on the health of secondary school students in Ogba/Egbema/Ndoni Local Government Area in Rivers State. Two research questions guided the study. This study adopted a descriptive study design. The study was carried out in Secondary schools in Ogba Egbema Ndoni L.G.A. The target population of the study was all students, teachers, and administrators of secondary school in Ogba/Egbema/Ndoni LG.A. The sample size of 200 people was randomly selected from five secondary schools in ONELGA for the study. The researcher used a sampling method to adequately manipulate the enormous population. The instrument used for data collection was a questionnaire. The test already possesses face and content validity before it was administered. The data for this study was collected directly by the researcher through the students, teachers, and proprietors of the selected schools in ONELGA. Data collected were analyzed using the SPSS statistical package. Frequency distributions and other descriptive statistics were used to present data. The findings of the study revealed that there has been an impact of solid waste disposal on the health of secondary school students in Ogba/Egbema/Ndoni Local Government Area in Rivers State. The researcher, therefore, recommended that there should be adequate dumping sites for solid waste provided by the government for schools, the dumping sites for refuse should be far away from the school environment. Wastes disposal equipment should be provided for schools to avoid dumping waste in the environment and to also avoid the decay of these wastes in the school environment to avoid many diseases, there should be funds raised for programs to orientate students on proper waste management.

Many rising health complications plague countries worldwide. Air pollution and global warming are some of the most significant contributors. In developing countries, i.e., China, India, or Guatemala, people are contracting severe illnesses such as pneumonia, carbon monoxide poisoning, and various cardiac or respiratory diseases due to air pollutants mainly emitted during rapid economic development. Most under-developed countries are not able to provide sufficient funds for medical treatments or do not know the potential consequences of these diseases in the long run. Among various factors of air pollutants, carbon monoxide presents a significant threat, mainly because it is toxic and invisible to humans. Despite extensive research on the life-threatening effects of carbon monoxide poisoning, appropriate measures have not been fully executed. The objective of the study was to demonstrate the connections between rapid urbanization and carbon monoxide levels in an emerging country.  Our research team visited Guatemala to monitor carbon monoxide levels in diverse locations of varying conditions: population, residence, transportation, urbanization, or use of different ventilation. In areas with high-level carbon monoxide (CO), an Easy Log El-USB-CO was used. In highly populated urban areas, the CO level reached up to 200 ppm, and elevated approximately 5 hours, though ups and downs. Our results supported the claims that people in Guatemala have been intoxicated with carbon monoxide and that a central government should find ways to combat this ongoing, silent epidemic.

THE ROLES OF URBAN AGRICULTURE FOR CLIMATE CHANGE ADAPTION IN THE CASE OF DEBRE MARKOS TOWN AND SURROUNDING DISTRICTS EAST GOJJAM ZONE AMHARA REGION ETHIOPIA

Journal of Global Ecology and Environment, Page 87-94

Rapid urbanization and large scale food production both heavily dependent on fossil fuels are arguably the most significant contributors to climate change. They are also increasingly recognized as potential tools in mitigation and adaptation to climate change. Climate change has already affected food production systems leaving loss of crop, grain shortages, and increased commodity price in its wake, all of which undermine food security a fundamental human right. This study establishes that Urban Agriculture is a multipronged tool for adaptation and mitigation to tackle climate change, and is the effective tool to address food security challenges in the cities, educate and reconnect urban and peri urban farms and people to assure food and climate security in the cities.
