Ecological sanitation (Ecosan) technology was introduced to improve sanitation through the reuse of excreta resources, particularly in developing countries. However, the adoption of Ecosan technology is low which makes its diffusion complex, especially in diverse spatial and socio-cultural contexts. This review of literature aimed to use the innovation theory to identify the issues that make the process of adoption of Ecosan technology complex. A total of 105 published studies were reviewed. Of these, only 34 studies were analyzed and grouped according to the complexity of the diffusion of Ecological sanitation technology using the five stages of innovation diffusion conceptual model identified by Everett Rogers (2003) namely: knowledge, persuasion, decision, implementation, and confirmation. The studies revealed the existence of diverse complexities of adoption, such as lack of sanitation policy, phobia against the use of Ecosan by-products, lack of technical support, and safety issues. In addition, poor practical knowledge, illiteracy, high capital cost, disgust with human excreta, religious taboos, and cultural boundaries were also found to hinder the smooth diffusion of Ecosan technology in various geographical settings. The scale-up of Ecosan technology, therefore, needs to focus on addressing these barriers and adopting implementation best practices.

The ecological sanitation (Ecosan) technology continues to be challenged by diverse factors including exposure of human excreta to the users in different geographical settings. The purpose of the study is to understand the linkage between the uptake of Ecosan technology and theapplication of human excreta on the farms among farmers in Burera district. A quantitative study was conducted to assess the linkage between the application of human excreta on the farms and the uptake of Ecosan technology among farmers of Burera District, Northern Province of Rwanda. By using a multistage sampling strategy, a sample of 361 household farmers was selected in the sectors of Rugarama, Gahunga and Cyanika in the District of Burera where the Ecosan technology has been mostly implemented at the household level Findings show that Ecological sanitation  technology is favorable among females and 70% of females prefer to use it as sanitation facilities due to its privacy and design compared to the pitlatrine technology. In addition, the application of human excreta on the farm was high and 60% of farmers apply excreta on the farmers especially when there is a time of emptying excreta from their sanitation technologies. However, only 3% of the users of Ecosan technology apply also human excreta as Ecosan products on their farms. This implies that there is a need to scale up the Ecosan technology in the community of Burera district to optimize the proper use of human excreta. The high uptake of Ecosan technology will evolve the implementation strategies such as community education, the supply of Ecosan materials in the community and the construction of Ecosan technology. This will boost sanitation coverage and increase crop production in Burera district by taking into account the community health as well as the environmental aspect

Human-Wildlife Conflict (HWC) makes wildlife conservation more difficult and threatens the endangered species and human livelihood in adjacent protected areas. While the cases of existing conflicts are often evaluated, their trend vis-à-vis the mitigation measures such as an electric fence has been frequently overlooked. This study aimed at evaluating the trend of human-wildlife conflicts in and around Akagera National Park (ANP) by comparing the situations before and after its electric fencing. This study used both secondary and primary data. Secondary data used exiting literature while primary data has been obtained by using field observation, household questionnaire survey, and Key Informant Interview with park managers and local leaders.The findings revealed that both illegal activities from local population and damages from wild animals have significantly reduced if we compare the situations before and after the establishment of an electric fence around ANP in 2013. In fact, between 2011 and 2020, illegal activities in the park have reduced to 70 %, 80 %, 85 %, and 80 % for captured cows, caught poachers, found traps, and killed animals respectively. However, this electric fence has not yet eradicated all forms of human-wildlife conflicts to the extent of zero case. In this regard, a set of sustainable community-based conservation strategies such as revenue sharing scheme, insurance scheme, compensation measures, etc., is highly encouraged.

Background: The utilization of “on-site excreta decomposition technology” known as “Ecological sanitation (Ecosan)” has a rational use of human excreta. It is a resource-oriented sanitation mostly feasible in areas with rocky soil and prone to agriculture. This technology was implemented in Rwanda for more than a decade. However, little is known about Ecosan utilization in the process of scale-up in the community. Aim: The study was carried out to determine enablers and barriers associated with the utilization of Ecosan in Burera district, Rwanda. Methods: A mixed method study was surveyed in 374 households with Ecosan. A systematic random sampling was used to select respondents and a sample was drawn from the 3 administrative sectors of Burera district. We interviewed 20 key informants that included community leaders and sanitation actors. Bivariate, ordered logistic regression with thematic content analysis were used. Results: Ecosan users were unable to practice both urine diversion and the use of Ecosan by-products. Only 39.4% of households were better users. As by the survey results, primary and secondary educational status (AOR 2.60, 95% CI 1.11-6.08) and (AOR 3.49, 95% CI 1.02-11.9), frequency of fecal pit emptying (AOR 3.38, 95% CI (2.18-17.91), ash use (AOR 1.65, 95% CI (0.93-4.64) and concrete slab latrine (AOR 7.31, 95% CI (2.94-17.95) were found to be associated with better use of Ecosan. Qualitative findings suggested unaffordable cost, a touch of excreta taboos, and poor maintenance practices as key barriers to utilization. Conclusion: Overall utilization of Ecosan was poor and the majority of households was not able to use Ecosan for both dry separation of urine from feces and reuse in the gardens. Upgrading existing knowledge about Ecosan with greater emphasis on the use of by-products and adopting good maintenance practices through regular training can promote better utilization of Ecosan.
