A hidden opportunity: Collaborative Development of teaching and learning in Environmental Geochemistry and Health at the Department of Geology, University of Calabar, Nigeria

 

The topic of Environmental Geochemistry has existed as a postgraduate course of study in the Department of Geology, University of Calabar in Nigeria for the past eighteen years. After my Commonwealth Academic Fellowship in 2008-2009, hosted by Prof A.S Hursthouse at the School of Science, University of the West of Scotland, I became a member of SEGH. The skills acquired during this period and as a registered member of SEGH, we decided to review the existing environmental geochemistry curriculum during my tenure as the Head of Department in 2012, since being established in 1976, its first female to hold that post.

 

Through my colleagues in SEGH, I was able to consult widely with members of the International SEGH board to review and gather opinion on the programme topics and syllabus content. This exercise was of great help and a real benefit to get feedback from the environmental geochemistry and health community, giving a real international perspective. It has helped to provide a good justification for changes to the programme in discussion with our University. The course was approved as an area of specialization under Environmental Geoscience section starting from 2013/2014 session. It is among the courses currently being advertised by the graduate school for this session and it will be in cooperated into the new graduate school brochure of the University to help to give it a wider publicity. It is anticipated that in future this will be extended to the undergraduate level when the curriculum will be reviewed as well.

We also hope that with further support from the members of SEGH we will be able to carry out some collaborative research where we lack the necessary laboratory facilities and some graduate students will be able to benefit from the expertise of SEGH members as the need arises.

At this juncture, I would like to thank members of SEGH for their input in structuring of the curriculum.

  • The influence of application of biochar and metal-tolerant bacteria in polluted soil on morpho-physiological and anatomical parameters of spring barley 2020-01-27

    Abstract

    The paper presents the results of the model experiment on spring barley (Hordeum vulgare L.) grown in polluted soil. The influence of separate and combined application of wood biochar and heavy metal-tolerant bacteria on morpho-physiological, anatomical and ultrastructural parameters of H. vulgare L. has been studied. The joint application of biochar and bacteria increased the shoot length by 2.1-fold, root length by 1.7-fold, leaf length by 2.3-fold and dry weight by threefold compared to polluted variant, bringing the plant parameters to the control level. The maximal quantum yield of photosystem II decreased by 8.3% in H. vulgare L. grown in contaminated soil, whereas this decrease was less in biochar (7%), bacteria (6%) and in combined application of bacteria and biochar (5%). As for the transpiration rate, the H. vulgare L. grown in polluted soil has shown a decrease in transpiration rate by 26%. At the same time, the simultaneous application of biochar and bacteria has led to a significant improvement in the transpiration rate (14%). The H. vulgare L. also showed anatomical (integrity of epidermal, vascular bundles, parenchymal and chlorenchymal cells) and ultrastructural (chloroplasts, thylakoid system, plastoglobules, starch grains, mitochondria, peroxisomes, ribosomes, endoplasmic reticulum, vacuoles) changes, revealed by light-optical and transmission electron microscopy of leaf sections. The effects were most prominent in H. vulgare L., grown in polluted soil but gradually improved with application of biochar, bacteria and their combination. The use of biochar in combination with metal-tolerant bacteria is an efficient tool for remediation of soils, contaminated with heavy metals. The positive changes caused by the treatment can be consistently traced at all levels of plant organization.

  • Earthworms and vermicompost: an eco-friendly approach for repaying nature’s debt 2020-01-23

    Abstract

    The steady increase in the world’s population has intensified the need for crop productivity, but the majority of the agricultural practices are associated with adverse effects on the environment. Such undesired environmental outcomes may be mitigated by utilizing biological agents as part of farming practice. The present review article summarizes the analyses of the current status of global agriculture and soil scenarios; a description of the role of earthworms and their products as better biofertilizer; and suggestions for the rejuvenation of such technology despite significant lapses and gaps in research and extension programs. By maintaining a close collaboration with farmers, we have recognized a shift in their attitude and renewed optimism toward nature-based green technology. Based on these relations, it is inferred that the application of earthworm-mediated vermitechnology increases sustainable development by strengthening the underlying economic, social and ecological framework.
