Programme Animation

The project animation production has been completed and the outputs include English Version Animation, Chinese Version Animation and 6 editable illustrations that we can use to promote the work of the project. Here the animation explains what is the Critical Zone and the holistic approach the programme is taking following the in-depth research in 4 regions of China to reveal ways to better sustain fragile environments. Agriculture decisions support tools are a good way to apply complex science to practical day-to-day decisions. They have been release on WeChat and YouTube – links below. The animation in both English and Chinese have…

Webinar of the results from Phase 1 of programme

In order to reduce the impact of the global epidemic on the knowledge exchange of the project, the Sino-British Earth Critical Zone Project specially recorded a webinar. The purpose is to publicize the natural science and social science research results of the Sino-British Earth Critical Zone Project through the form of web lectures, and maximize The key is the influence of scientific knowledge and social and ecological benefits. This video was recorded by the postdoctoral fellow of the project, Dr Ying Zhang. Please note the webinar is in Chinese. Link to the webinar

Analysing and simulating spatial patterns of crop yield in Guizhou Province Summary Sheet

A new summary sheet around the work completed by Boyi Liang during his time working on the research programme at Exeter University. The summary sheet focuses on  analysing and simulating spatial patterns of crop yield in Guizhou Province . Traditional models (including process-based models and statistical models) have been rarely studied in Karst region due to its complicated topography. Boyi found that back propagation network had the best performance based on both accuracy and runtime. Among the 13 influencing factors investigated, temperature (16.4%), radiation (15.3%), soil moisture (13.5%), fertilization of N (13.5%) and P (12.4%) had the largest contribution to crop yield spatial…

Working through COVID-19

MIDST-CZO was affected since January 2020 by restrictions due to COVID-19. Planned knowledge exchange activities in China in 2020 were replaced by online activities. From April 2020, UK partners have been working remotely from home. NERC/Newton Fund provided a no-cost extension to the project of 12 months, so it will now complete in March 2022. We were still active over 2020, with updates shown in the other website articles. Research Progress A desk study on decision support tool (DSTs) use in China’s agriculture found over 400 working examples. Weaknesses included a focus on yield, without consideration of environmental and economic…

MIDST staff

MIDST Staff update. We have had a fantastic group of staff working on the programme over the last couple of years. A number of the Post-doc positions have now been completed and the staff have moved on to new exciting projects. Dr Weikai Wang joined the group at the University of Glasgow, replacing Dr Ying Zheng as the Knowledge Exchange expert. He is a social scientist with specific expertise on land use and economic growth in China. Dr Boyi Liang from Peking University completed his academic visit at the University of Exeter in June 2020. He is still contributing to…

Deep Nitrogen Accumulation and Sources Summary Sheet

A new summary sheet around deep nitrogen accumulation and sources has been produced by the team highlighting the findings and relevance for policy making and practice. They found that land use and critical zone features (e.g. thickness of loess deposit, water regime) are key determinants of N accumulation patterns where agricultural inputs – e.g. fertiliser, manure and organic sources – are significant contributors. In the Loess plateau region, accumulated nitrate introduced by human activities is mainly distributed in the upper vadose zone (above 30 m), indicating there is currently a low risk of nitrate leaching into groundwater. A copy of the Summary…

Science-Policy-Practice Interface Summary sheet

A new summary sheet on the topic of ‘Science-Policy-Practice Interface’ has been produced based on the knowledge exchange research of Phase 1 project. A conceptual model of how the science-policy-practice interface works in China has been developed. Significantly-less awareness and use of two-way KE by Chinese government, scientists were identified. This summary sheet has been published on Project WeChat Platform together with the summary sheet of ‘Deep Nitrogen Accumulation and Sources’ and ‘Analysing and Simulating Spatial Patterns of Crop Yield in Guizhou’. Download the summary sheet at this link.

DST survey link

The UK team for phase 2 of the programme have produced an online survey about agricultural decision support tools. It was launched on Feb 1st 2021 on Wenjuan.com. Here is the link to the survey https://www.wenjuan.com/s/em2ENfU/ This questionnaire aims to understand the needs, habits and preference in the use and development of DST to support evidence-based decision making and promote decision support tools for agricultural management in China. We hope that civil servants, researchers, and relevant personnel engaged in agricultural work will participate in the survey. This survey was also disseminated via the growing WeChat Account: https://mp.weixin.qq.com/s/ev1324PYQwbFSd5jehvgYA please do join…

New research paper

Dr Boyi Liang from Peking University completed a visiting fellowship at the University of Exeter that was aligned to MIDST. Boyi Liang worked on the WOFOST DST which simulates crop production. He has been parameterising for maize, rice, tobacco, soya bean and potatoes. He produced a paper using neural networks to predict crop yield. The publication was published in in Progress in Physical Geography Earth and Environment.  While Boyi was in the UK he made use of Ian Bateman’s experience and incorporate investment model into his work. He continues to conduct CZO research complementary to the project. Liang, B.Y., Liu, H.Y., Quine, T.A., Chen, X.Q., Hallett,…
