Analysis of Adapted Sewage Sludge Treatment and Disposal Routes in Bujumbura, Burundi

Aaron Bizimana, Bing Wu, Aicha Abdallah Idriss
The disparities found in studies on sewage sludge management, aggravated by the high financial investment required, may lead to decision-making uncertainty and hesitancy. This research, basing on seven different sludge treatment and disposal routes that are widely used in China (thickening-anaerobic digestion-dewatering-land application, thickening-condi- tioning-dewatering-sanitary landfill; thickening-conditioning-dewatering- anaerobic digestion-land application, thickening-conditioning-dewate...

Design of a Co-Digestion Biogas Plant to Curb Deforestation-Case Study of Phalombe Secondary School in Malawi

Nyirenda Austin Kawelamzenje, Maurice Twizerimana, Dushengere Bernadette, Alexis Bakundukize
Biogas technology is one of the renewable technologies that use biodegradable waste such as human waste (HW), agricultural waste, animal and food waste. Over 90% of the population in Malawi is heavily reliant on firewood as their primary source of energy for cooking. This results in deforestation, pollution of the environment, and great monetary expenditure to buy firewood, more especially by boarding schools. A co-digestion biogas plant that uses human, animal, agriculture, and canteen food was...

Venomous Stings and Bites in the Tropics (Malaysia): Review (Non-Snake Related)

Xin Y. Er, Iman D. Johan Arief, Rafiq Shajahan, Faiz Johan Arief, Naganathan Pillai
The success in conservation and increase in number of nature reserves resulted in repopulation of wildlife across the country. Whereas areas which are not conserved experience deforestation and destruction of animal’s natural habitat. Both of these scenarios predispose mankind to the encounter of animals, some of which carry toxins and cause significant harm. This review dwells into the envenomation by organisms from the land and sea, excluding snakes which are discussed separately. Rapid recogn...

Drought Identification through Climatic Variables

Oluwarotimi Jacob Adegboye, Oluseyi Enitan Ogunsola
Temperature and rainfall are among the climatic variables required in determining the availability of water in an environment, especially for agricultural purposes and domestic consumption by man. However, there are concerns that these variables are being affected by global warming which thus necessitates the need to study their impact on the environment such as the identification of drought. The mean monthly temperature and rainfall data utilized in this work were obtained from the Nigerian Met...

Preliminary Assessment of Chiropteran Fauna within Kayam Forest (Inucarpus fagifer) in Barangay Pagatpatan, Butuan City, Philippines

Glenn L. Betco, Meljan T. Demetillo, Clyde Salanatin, Archie A. Along, Alvin B. Goloran
Bats conservation studies in Butan City particularly within Kayan Forest are poorly studied and not even documented in the place. This study was purposely conducted to document and identify bats species in the unique forest. Diversity and assessment were conducted in different strategic locations along the portion of the lower Agusan River particularly in a well-known Kayam Forest (Inucarpus fagifer) in Butuan City, Philippines. The bats’ assessment was made through the mist-netting captu...

A Comparative Study of Physico-Chemical Parameter in Glacial Melt Water, Ponkar Glacier, Nepal

Sandeep Shrestha, Rajendra Bhandari, Ashish Bashyal, Nischal Shrestha
We conducted a detailed study in comparing physico-chemical parameters of glacier melt water between two years (2016 & 2019) in upstream sites with an elevation ranging from 4100 m to 3550 m above sea level of Ponkar glacier, Manang district, Nepal. We conducted onsite testing of physical parameter like pH, electrical conductivity, total dissolved solids, turbidity by using multiprobes and chemical parameters like anions, cations, total silica and heavy metals were analyzed following standard me...

Exploring the Eco-Efficiency of Transport-Related Particulate Matter Pollution in Nairobi City, Kenya

Alfred Kipchumba Muge, Qian Jia, Ying Wang, Fengting Li
Eco-efficiency of the transport sector is a novel idea of high importance for reduced environmental pollution and sound resource use in Nairobi City. An assessment of transport eco-efficiency of the 11 sub-counties of the city was carried out for the period between June 2019 and May 2020 by examining the overall transport eco-efficiency levels, specific sub-regional variability in the efficiency and factors affecting efficiency. To realize this, a combined PCA-DEA-MLR approach is applied. The em...

An Assessment of the Water, Irrigation, and Food Security by a Fishbone Analysis in Turkey

A. Ahmet Yücer, Feyza Nur Ayhan
The use of water resources is ineffective although Turkey has insufficient freshwater resources. Dry farming is practiced in a large part of agricultural land. This land due to insufficient precipitation throughout the country is left to fallow once in two years. Agricultural drought is becoming a severe challenge for agriculture and food security, and it may also impact the wealth of farmers by agriculture income. So, it causes widespread concern among the rural population. There is a close rel...

Biochemical Treatment and Utilization of Fecal Wastewater

Haiyan Hu, Xin Zhou
In order to treat and utilize urban fecal wastewater more effectively, a process for biochemical treatment of fecal wastewater from urban settlements was established in this study. After treating the fecal wastewater collected, solid and liquid organic fertilizers can be obtained. Compared to the commercially available urea, the solid organic fertilizer can increase the yield of okra by 12.89% at podding stage, while the liquid organic fertilizer can prolong the flowering period of Chinese orchi...
