Abstract Background: The depletion of bioenergy sources has caused significant deforestation, low agricultural production and energy crisis. This study evaluates the technical potential of biogas technology adoption in replacing firewood, charcoal, kerosene and chemical fertilizer in Northern Ethiopia. Methods: Questionnaire household survey, key informant interview, focus group discussion and field obervation were used for data collection. Results: Biogas technology adoption reduced the use of firewood, charcoal, dung cake, and kerosene consumption by 58%, 36%, 71%, and 74%, respectively. It also reduced the use of chemical fertilizer by 94% and the combined use of chemical fertilizer and manure by 91%. Adoption turned the majority of households (65.4%) to use combination of bio-slurry and chemical fertilizer. It helped the majority (89.95%) of adopters to construct and connect toilets to biogas operational system. In doing so, adoption reduced defecation in the field and improved environmental sanitation and human health. It further enabled saving of about 38% of adopters’ time, which otherwise would be expended for firewood and dung collection. It similarly enhanced adopters’ income through decreasing expenses for chemical fertilizer, kerosene, and other fuel sources. Conclusions: Biogas technology has huge potential of replacing traditional fuel sources for domestic consumption, and of reducing the consumption of kerosene and chemical fertilizers as well as of increasing income and decreasing time for biofuel collection.

A rapid increase in climate researches by applying diverse methodologies and approaches in recent decades. These researches have directly or indirectly contributed in better understanding of climate issues, risks and vulnerabilities. It has improved awareness and capacities of the public and communities to adapt to the vulnerabilities and impacts. It, further, contributes in formulation of climate policies and plans to address climate risks and vulnerabilities at the local and national levels. Appropriate methodologies lead to better results in the researches. This paper has applied systematic review of the published papers (2010 -2017) to understand the general and specific research methodologies in climate discourse especially in Web of Science (WS), Springer Link (SL) and Science Direct (SD). Altogether, 37 journal papers (10 WS, 13 SL and 14 SD) were selected for the detail analysis based on the assessment of abstracts, which was mainly concentrated on research methodologies specializing in agriculture. In the process, the authors have analyzed the contents, research methodologies, data analysis, and geographical coverages.

Soil fertility decline has pushed farmers across the world to resort to chemical fertilizers in order to improve soil fertility and enhance crop yields. In agroforestry systems, the application of chemical fertilizers is a call for concern considering that agroforestry systems are supposedly agro-ecological, environmentally friendly and sustainable systems. It was within this context that this study sought to assess the application of chemical fertilizers in cocoa-based agroforestry systems and its policy ramifications. Data was collected through a household survey of 300 cocoa farmers in Cameroon, and analyzed on SPSS 17.0 employing descriptive and analytical techniques. It was found that the most commonly used chemical fertilizers by cocoa farmers in cocoa-based agroforestry systems were NPK 20:10:10 (60%), NPK 15:20:15 (50%), and Urea (40%). It was also noticed that a majority of the cocoa farmers sampled used no chemical fertilizer (35%), very small quantity (15%), small quantity (20%), and moderate quantity (20%). With respect to frequency of use, most cocoa farmers never used chemical fertilizer (35%), used it rarely (30%), or used it occasionally (15%). However, some cocoa farmers used chemical fertilizers frequently (5%) and very frequently (5%) in their cocoa agroforests. Coefficients of correlation and regression showed the existence of a statistically significant (p<0.05) direct and inverse non-causal and causal relationship between different explanatory variables (income level, availability of chemical fertilizers, access to information, membership in farming group and access to extension services) and cocoa farmers’ use of chemical fertilizers; while farm size and number of farms had a statistically significant inverse relationship. Correlation and regression coefficients showed the existence of a statistically significant (p<0.05) direct non-causal and causal relationship between different levels of cocoa yields (very high cocoa yield, high cocoa yield, average cocoa yield, low cocoa yield, very low cocoa yield, no change in cocoa yields) and the application of chemical fertilizers in cocoa-based agroforestry systems. On the basis of the study’s findings, it is recommended that measures be taken to limit the use of chemical fertilizers in cocoa-based agroforestry systems in order to enhance the sustainability of these systems.

In Ethiopia, medicinal plants had been used since ancient time and became an important source of health care. Though majority of the people in the study area depend on ethnomedicine to manage different ailments, the indigenous knowledge largely is not documented. As a result, an ethnobotanical survey was conducted with the objective of assessing the role of medicinal plants in traditional medicine. Data was collected by using semi-structured interview and group discussion. Twenty informants were purposefully selected based on indigenous knowledge and gender. Ethnobotanical data was analyzed with descriptive statistics and expressed in tables and flow charts. A total of 25 medicinal plants (22 families) recorded to treat human and livestock ailments. Medicinal plant habit analysis indicates that shrubs occupy the highest proportion (36%), followed by trees and herbs (28% for each) and climbers (8%). The most commonly used plant parts in the study area were leaves and roots. Although medicinal plants play a great role in the society, their  sustainability is declining through time in the study area due to the increasing number of users, improper uses of the plants and poor conservation. Therefore, the conservation of these medicinal plants would be important.

This study was conducted in Murut indigenous people inhibited two villages of Keningau district of Sabah Borneo which is blessed with vast cultural diversities. In this regard, 120 randomly selected households from the Nabaai and Gana tribes of Murut community were investigated with a view to identify their homestead plants, use pattern and also their Traditional Knowledge on plant utilization. Five major research tools (e.g., review of secondary information, key Informant interview, household survey with semi-structured questionnaire and focus group discussion) was employed in this study. It is found that the plant species found in the homestead of the Nabaai and Gana tribes are utilized for three main reasons i.e., i) food production, ii) medicine, and iii) fuel wood. There are 23 utilization pattern has been identified in this study which is much lesser than what was found a decade ago (68 utilization). The Nabaai and Gana tribes practice Traditional Knowledge in their daily life especially, in medicinal plant utilization. The findings also show that most of the Traditional Knowledge on plant utilization is lying with the respondents with low income group (59%) because of their high dependency on utilization of the surrounding resources in their daily life. Appropriate steps to preserve and conserve the Traditional Knowledge on plant utilization possessed and practiced by the Murut indigenous communities are deemed necessary before this huge nature treasure is forgotten.

Dumanquillas Bay is a body of saltwater and the major source of food located in the Southern Mindanao. It has been observed that marine resources and fish catch in the area are declining. This study assumed that fishing practices affect the decline of marine and fish catch in the bay. A study on the documentation of fishing practices in the area is reported here. Key informant interview (KII), focus group discussion, direct observation and document archival were used. Twenty-three (23) fishing practices were observed in the area. Based on R.A. 10654 or the Philippine Fisheries Code, five (5) fishing practices were identified in the bay which are illegal. These are “pahulbot sa lalum”, “pahulbot sa mabaw”, “panubli”, “panguryente” and “troll” that destroys sea grasses, coral reefs and the sea beds. The illegal fishing practices identified poses a threat to the marine resources. It implies weak implementation of fishing policies among the LGU’s and other concerned government institutions and NGA’s. Capacity building, CEPA campaign and committed implementation of the Philippine Fisheries Code (R.A. 10654) should be implemented by the PAMB and stakeholders in the community to manage the remaining coastal marine resources thereby uplifting the socio-economic status of the coastal community and achieve sustainability.

This survey research based study sought determinants of biogas technology adoption in rural areas of Pakistan. Stratified random sampling technique was employed to select respondents because the population was unknown and heterogeneous in nature. Total 240 respondents (150 biogas users and 120 potential users) were selected and face to face interviewed using a structured, validated and pre-tested questionnaire. Along with descriptive analysis of data logistics regression model was applied to investigate the determinants of biogas adoption. Findings affirmed significant role of socio-economic characteristics  of respondents in the adoption of biogas technology. Empirical findings reported a significant impact of education, the income of households and the number of animals on the adoption of biogas technology. This implies that unit increase in education, income and number of animals will escalate the adoption of biogas technology. Tackling energy crisis, economic benefits, and production of slurry for soil fertility, health gains and environment-friendly nature of biogas were perceived reasons of biogas adoption among the biogas users. Non-government organizations and neighbours were leading motivational factors behind adoption as revealed by users. However, role of electronic media, print media and government institutionsin promoting biogas was reported dismal. This study urge that biogas is valuable alternative source of energy to combat energy crisis. In this way, provision of subsidies, interest free loans and technical backstopping could invoke potential users to adopt biogas technology.
