Editorial: The society for environmental geochemistry and health (SEGH): 50 years and beyond

When the SEGH international board released a short editorial paper back in 2019, we described an aim to increase the membership offering, whilst improving the diversity of input regionally, by scientific discipline and to ensure greater and more regular contact across the regions from 2020 onwards. Wider aspirations described in 2019 (Watts et al. 2019) are discussed within this short communication at the end of 2021 to evaluate progress made. In particular, how the SEGH community adapted to the unprecedented circumstances that have challenged each and every one of us throughout the COVID-19 pandemic since early 2020 and are likely to influence our activities for the foreseeable future

The Society for Environmental Geochemistry and Health (SEGH): building for the future of early career researchers

In a 2019 editorial entitled ‘The Society for Environmental Geochemistry and Health (SEGH): building for the future’ (Watts et al. 2019), SEGH President Dr Michael Watts and all current board members outlined their aspirations and initiatives for the Society’s expansion into the new decade and beyond. Central to these efforts was the establishment of a dedicated group of early career researchers (ECRs) within SEGH to foster interaction, collaboration, mentorship and ultimately the expansion of this demographic. SEGH defines ECRs as undergraduate or postgraduate (Masters/PhD) students or as scientists having received their highest degree (BSc, MSc or PhD) within the past 5 years. ECRs currently make up approximately 20% of SEGH memberships, and nurturing growth at grassroots level is a critical strategy in preserving the Society’s long-term future if it is to remain relevant in an ever more competitive research landscape. With this in mind, ECR representatives currently sitting on the board took the initiative to follow up the 2019 editorial from an ECR perspective, with contributions made exclusively by members of this group. Drawing from personal experiences, we focus on key aspects of SEGH as a society and a community, but more importantly as a wider discipline and career path. We highlight the unique selling points of SEGH membership to ECRs, while voicing our wishes for improvement with the overall aim of promoting the society, and the society’s core values. Our hope is that we can attract more ECRs to our diverse community and enhance the experience of our current members

The Society for Environmental Geochemistry and Health (SEGH): building for the future.

The challenges of sustainable development are ever more pressing, and the skills, interests and capabilities of the SEGH member are well-placed to continue to make more meaningful contributions to the environment, society and well-being. We reflect on the historical development of the society, its response to the dynamic international research landscape and the great opportunities ahead. In 2018, SEGH implemented a new board structure after 2–3 years of consultation, with approval of a new constitution and a new strategy across the large number of international board members. While regions were represented by sections in Europe, Asia/Pacific and the USA, the structure required renewal in order to be more representative of the distribution of members and website traffic that had evolved in preceding years. In addition, the society wanted to improve its position for future growth opportunities across rapidly developing regions

Planning spatial sampling of the soil from an uncertain reconnaissance variogram

An estimated variogram of a soil property can be used to support a rational choice of sampling intensity for geostatistical mapping. However, it is known that estimated variograms are subject to uncertainty. In this paper we address two practical questions. First, how can we make a robust decision on sampling intensity, given the uncertainty in the variogram? Second, what are the costs incurred in terms of oversampling because of uncertainty in the variogram model used to plan sampling? To achieve this we show how samples of the posterior distribution of variogram parameters, from a computational Bayesian analysis, can be used to characterize the effects of variogram parameter uncertainty on sampling decisions. We show how one can select a sample intensity so that a target value of the kriging variance is not exceeded with some specified probability. This will lead to oversampling, relative to the sampling intensity that would be specified if there were no uncertainty in the variogram parameters. One can estimate the magnitude of this oversampling by treating the tolerable grid spacing for the final sample as a random variable, given the target kriging variance and the posterior sample values. We illustrate these concepts with some data on total uranium content in a relatively sparse sample of soil from agricultural land near mine tailings in the Copperbelt Province of Zambia

Editorial: Charting achievements: a two-year retrospective of the society for environmental geochemistry and health (SEGH) and the evolving strategies

Emerging from the shadow of the COVID-19 pandemic, it is time to ground ourselves and retrospectively assess the recent achievements of SEGH over the past years. This editorial serves as a comprehensive report on the progress made in comparison to the aspirations and goals set by the society's board in 2019 (Watts et al., Environ Geochem Health 42:343-347, 2019) (Fig. 1) and reflects on the state of the SEGH community as it reached its 50th anniversary at the close of 2021 (Watts et al. Environ Geochem Health 45:1165-1171, 2023). The focus lies on how the SEGH community navigated through the extraordinary challenges posed by the COVID-19 pandemic since early 2020, and to what extent the 2023 targets have been met
