Adewole Michael Gbadebo a Professor of Environmental Geochemistry at the Department of Environmental Management and Toxicology, Federal University of Agriculture, Abeokuta, Nigeria shares his experience of SEGH2019

I arrived at Manchester Metropolitan University (MMU), venue of the 35th SEGH conference at around 4 pm on Monday 1st July 2019  where  I was welcomed by Prof. Sanja Potgieter-Vermaak. On the morning of  Tuesday 2nd July 2019, I came to the venue of the conference from my hotel registered for the conference, mounted my poster on the assigned billboard, attended the welcome and introduction section and attended the day’s sessions (comprising of morning and afternoon sessions). Each session started with keynote speakers’ presentation followed by 15 minutes of Platform /Oral presentations and 2-minute flash presentations with an interlude of lunch break before the afternoon section. I was at my poster stand during the break periods to present my work to poster viewing conference-participating-audience. This I did routinely from Tuesday 2nd – Thursday 4th July 2019.

I also attended behind the scenes evening social at the Manchester City Football Stadium on the evening of Tuesday 2nd. I remember hearing Prof Sanja Potgieter-Vermaak mention that participants at the conference were from 15 countries of the world including Nigeria. At the end of the conference, during the closing ceremony/remarks, hosts of the 36th and 37th SEGH in Kenya and China were announced and acceptance speeches were given by Prof Odipo Osano from Kenya and China representatives. Prizes were given to the best poster presenter and people who worked with Prof Sanja Potgieter-Vermaak to make the conference a huge success. This was capped with SEGH AGM which took place on Thursday at the same venue of the conference with the delegates (conference participants) in attendance and Dr Michael Watts from BGS was re-elected as the chair of SEGH.

With regards to networking opportunities, the conference afforded me opportunities for meeting professional colleagues from diverse institutions and fields of specialization and interests. I was able to discuss with these scientists, possibilities of research collaborations. Some of these people include but not limited to: Michael Watts (BGS); David Manning (on carbon-capturing); Ricardo Godoi (on Pollen & Hospitality); Paul Preton (on Brownfield Sciences); Khadija and Jane (on Household Dust); Alex Stewart (on Iodine Diseases in Nigeria, Nee Africa).

I am grateful for the SEGH bursary I received as an international participant from a developing country.

  • 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


    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


    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.
