Effective management of these three resources requires careful assessment of synergies, conflicts and trade-offs which are inherent in the nexus. In Kenya, the achievement of sustainable development goals relies on the management of these key resources. Climate variability and climate change bring uncertainty to water, energy and food situations in the country. Over 75% of agricultural activities in the country are rainfed and thus risky in the face of the poor temporal and spatial distribution of rainfall. Energy reliability is low in Kenya due to the dependence on hydropower sources which are prone to climate risks. This review highlights the importance of the WEF nexus in the face of climate change impacts. Climate adaptation mechanisms for building resilience in cropping systems, water service and energy provision are key elements for the improvement of livelihoods. It is imperative to address sustainably and holistically the three key sectors through policy, legal and institutional frameworks and initiatives. Assessment models and tools are developed to monitor the attainment of targets under WEF.

This has led to isolation of key microbes known to degrade these persistent pesticides in soils. The isolated microbes which are characterized and identified have been used to enhance the degradation of pesticides in contaminated soils and hence the term, bioaugmentation. In this paper we discuss various pesticide compounds which for so Proceedings of the Second International Research Conference 28th to 30th October, 2015 228 long were known to be recalcitrant, but later could be subject to accelerated degradation. Key degraders were isolated and characterized and are potential candidates for bioaugmentation for remediation of contaminated sites. We report the successes registered in studies of atrazine, terbuthylazine, hexazinone, diuron, carbofuran and chlorpyrifos and metribuzin.

Water pollution due to organic contaminants has been a serious issue in developing countries because of the acute toxicities and carcinogenic nature of these pollutants. Among various water treatment methods, adsorption is purported to be one of the best because it is cheap and easy to prepare and use. Initially, activated carbon was being used in water treatment to remove contaminants but it proved to be expensive and also it did not degrade these contaminants after adsorption. For this reason, zinc oxide nanoparticles are synthesized for recommended use in the degradation of pesticides. The zinc oxide nanoparticles were synthesized using Cissus quadrangularis plant leaf extract. The surface analysis of the synthesized nanoparticle was analyzed using a particle analyzer and X-ray diffraction (XRD) crystallography. The synthesized nanoparticles were found to have a mean diameter of 14.83 nm and the XRD pattern revealed the formation of ZnO nanoparticles showing crystallinity. The synthesized ZnO nanoparticle showed a characteristic peak at a wavelength of 368 nm for electron excitation. This simple and cost-effective phytochemical approach for the formation of ZnO nanoparticles has a promising application in biosensing, photocatalysis, electronics, and photonics Wed, 06 Apr 2022 00:00:00 GMT https://ir-library.mmust.ac.ke/xmlui/handle/123456789/2491 2022-04-06T00:00:00Z https://ir-library.mmust.ac.ke/xmlui/handle/123456789/2366 Mentoring in Nursing through Narrative Stories Across the World Karani, Anna; Wachira, Serah; Kaniaru, David This section of the book discusses mentoring experiences of a mentor and two mentees during the COVID-19 pandemic. The reflections clearly explained the journey from the perspective of the mentor and mentees. The reflections explain the journey, the handles, and the eventual success of the mentoring process despite the challenges presented by the pandemic to the teaching and learning arena. Generally, the goals of mentoring were achieved and every party expressed satisfaction and growth in the nursing profession.
