MIDST-CZ: Maximising Impact by Decision Support Tools for sustainable soil and water through UK-China Critical Zone science

Lead Research Organisation: University of Aberdeen


This collaborative UK-China project proposes will establish a suite of Decision Support Tools (DSTs) that incorporate knowledge advances from the ongoing Phase 1 UK-China Critical Zone science research programme. With these advances, DSTs currently used in the UK and China will be adapted, expanded, tested and applied. The DSTs, data sets and decision outcomes will guide and evaluate site-specific innovation in soil and water management, and create roadmaps to scale up impact outcomes and plans to regional and national scale in China. The project will integrate the teams and research results of the 5 projects funded in Phase 1. Phase 2 will deliver immediate innovation in decision support methods and their application, and pathways to long-term impact and ODA outcomes: to restore ecosystems, improve soil fertility and water quality, improve farming livelihoods and improve food and water security. Impact delivery will focus on 5 critical zone observatories (CZOs) in China, established in Phase 1, which are located in regions with large-scale environmental and economic challenges related to degraded soil and water resources.

1. Hydro Karst CZO in SW China - land use and water quality linked to nutrient contamination of aquifers and surface waters in transmissive carbonate terrain
2. Peri-Urban CZO in the Yangtze delta - soil contamination from urban atmospheric deposition and intensification of agricultural chemical use
3. SPECTRA Karst CZO in SW China - Ecosystem degradation and karstic desertification linked with soil erosion and loss of soil fertility
4. Red Soils CZO - loss of soil fertility from intensification of agricultural production
5. Loess CZO - ecosystem degradation under intensification of rural land use

Participatory research with stakeholders in China will identify the land, water and food demand conflicts that need be addressed in the regions of the CZOs. This KE is designed to avoid a recognised mismatch between the way DSTs are conceptualised by scientists and how DSTs may be most effectively used by stakeholders. Recent reviews of DSTs for land, water and food sustainability provide a platform for assessing the suitability of different DSTs to the challenges of China. The UK and China teams and stakeholders will identify the most promising DST approaches and test these using the data sets of the 5 CZOs. The outputs will be tested with a wider set of DST users and potential users. The outcomes will allow mapping DSTs and their suitability to address soil and water management challenges at the 5 CZO sites. This work will assess effectiveness of the DSTs across the scales of interest for stakeholder groups at the sites. This will include identifying sustainable practices, the scale at which the CZO and related measurements strengthen the evidence base and inform practices for management decisions, and how adaptations in a DST methodology would improve site-specific application. The project will apply national data sets on the geographic variability of soil and water resource demand and use patterns, and natural conditions of geology, soil, vegetation cover, climate and weather. Through engagement with regional planners, the project will design pathways to scale up the DST outcomes for application in regional-scale resource planning. The final stage will be synthesis of the adapted, applied and upscaled DST methods into practical guidance in how to deploy the DSTs in regionally specific contexts, the capabilities of different DSTs and applicability of DST outputs. The institutional partners in China will publish the guidance and organisations will be identified and trained as superusers to disseminate training. Superusers will conduct a series of regional workshops in China, led by Chinese partners, to create a network of users who are at the forefront of innovation in soil and water management planning and implementation.

Planned Impact

The following will benefit from this research:
1. Those living in and managing the land for food production, and soil and water quality, and their conservation will benefit from the decision support tools (DST) that will be refined or developed based on our Critical Zone integrated understanding of how the environment functions. These tools will allow these stakeholders to be guided on best management practices for their business and the environment. The DSTs will lead to improvements in their quality of life, ensuring the fundamental needs (generation of food and associated economic development; access to water of appropriate quality) and decisions of how to achieve these, are underpinned by a useful knowledge-base.
2. Commercial organisations that depend on innovation, such as 'app' developers will benefit from our engagement with them to explore in what form the decision support tools should be made available. Moreover, the DSTs will be useful to agronomists and the fertiliser industry. Specific interest from two Chinese companies producing nutrients from sewage and other organic wastes has been demonstrated in letters of support.
3. This joint research will remain of benefit to the NSFC, raising their profile in the UK and amongst other critical zone scientists. The exchanges of skills and information that will occur during this research with Chinese colleagues will build international competitiveness of science in both UK and the UK. The research will ultimately demonstrate to the international scientific community the value sensitive environments, and the benefits of international cooperation in research to tackle grand challenges of food security, land degradation and climate change. It will help consolidate each country's position as a future key research partner, and particularly the NSFC in China as a partner of choice for future co-funded research with the UK.
4. Through publication and conference activity, the Chinese and UK academic parties will demonstrate to the community how their scientific endeavour can be used to create tangible outputs to improve the quality of life and global environment for those on low incomes or managing degraded land. They will benefit through enhanced international standing and resultant funded research collaboration.
5. The wider public, and local communities hosting the research, will benefit during the research activity through research team communication activity that meets their passion for and excites them to understand the natural world more deeply. This also includes those not involved directly in the research who may be asked to help gather data and in turn will receive training in new skills. In turn if this encourages greater interest in how STEM subjects also inform social development, the relevant country science base will benefit.
6. Through progress towards achieving sustainable development goals the global community will benefit.

Description MIDST-CZO used cutting-edge science from the UK/China Critical Zone Observatory projects to develop the foundation of a new class of decision support tools (DSTs) to support agriculture and the environment at the same time. Economic impacts of agricultural management decisions were also considered by adopting the natural capital approach. Another facet of the research was to close resource loops in peri-urban agriculture by making better use of urban waste to produce fertilisers where nutrients are mined from sewage and other urban organic waste streams. Knowledge exchange is pivotal to the success of the project. We actively conducted socio-economic surveys in China to learn about demands for DSTs to support agriculture, based on existing gaps in available tools and improvements that could be made to increase uptake of DST use. This was the first time that humans have been integrated into critical zone science. In collaboration with China, we produced functional DSTs for policy makers that aim to improve farming decisions to decrease environmental threats. The vast dataset generated from the UK/China CZO programme has also been used to develop new models that describe the interaction between agriculture and environmental processes. These will help form the foundation of future DSTs.

We have now completed just over 3 years of research on this project. The past two years, 2020-2022, were severely affected by COVID-19 restrictions, which was addressed to some extent by a no-cost 12-month extension and adaptation of our knowledge exchange activities with China.

A critical activity to project delivery is Stakeholder Workshop 2 (WP1). In early 2019 we had Stakeholder Consultations with a number of groups through face-to-face meetings covering broad geographical regions of China from Guangzhou to Beijing. We also held Stakeholder Workshop 1 later in 2019 in collaboration with the Jiangsu Academy of Agricultural Sciences. This provided broader interaction with stakeholders at the interface between science and policy. From these activities, we have learnt that targeting agricultural industry conferences will increase the reach of our work for Stakeholder Workshop 2. Webinars and online surveys also formed part of our original KE activities with China. These have been enhanced to maintain continuity during the COVID-19 lockdown, but they do not replace the need for face-to-face interaction with stakeholders. It has been impossible to hold face-to-face activities.

Work continued analysing knowledge exchange activities, informed by questionnaires and surveys conducted on previous visits and enhanced by new online surveys. We found that communication from government to farmers differed between regions in China, so local solutions would be needed. In some regions, farmers relied too much on fertiliser providers to make decisions, based primarily on crop yield. However, provincial agricultural research institutes in China are actively addressing knowledge exchange through the provision of online platforms, simple decision support tools and training. There is a strong demand for improved tools to address environmental threats caused by agriculture. Some existing DSTs to address yield and fertiliser use, such as Nutrient Expert, work extremely well, but could be extended to consider environmental impacts.

A challenge with survey work is reaching a wide audience, particularly when travel is constrained due to COVID-19 restrictions. Animations with Mandarin and English voiceovers were created to publicise the CZO projects in China. We also established a number of online delivery platforms, such as a WeChat public account that has attracted over 2000 reads to some articles we have posted. Summary sheets are continuously being prepared from our research outputs to be targeted at lay audiences. We also produced a new online survey 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. The target audience is civil servants, researchers, and relevant personnel engaged in agricultural work.

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 impacts. The data are analysed and a paper will be submitted in 2021 by the University of Aberdeen team. China has a strong research programme developing DSTs for agriculture. One of the leading tools is Nutrient Expert, which is very effective at improving nutrient use efficiency for a range of crops across China.

Rothamsted Research and their partners in China worked with a DST to predict the interaction between soil carbon storage and crop yield for the Loess Plateau. This couples agricultural output with environmental impacts. Further work needs face-to-face interaction, but a paper is expected this year.

Dr Boyi Liang from Peking University completed a visiting fellowship at the University of Exeter in 2020 that was aligned to MIDST. He continues to conduct CZO research complementary to the project and produced a paper using neural networks to predict crop yield.

Di Sheng, a postdoctoral fellow at the University of Exeter commenced in 2021. She has brought together agricultural, environmental and economic modelling to drive a new class of DSTs. In the 9 months that she has been in post, she now has a regional model on crop choice optimisation based on economic and environmental drivers for Guizhou.

Research continued at the Peri-Urban CZOs. Nanjing University and Leeds University furthered their partnership with joint PhDs as part of a Key Belt Project. Chemical (Queens University Belfast) and microbial (Sheffield University) analysis continues with some delays due to restricted lab and field access. A CSC funded PhD student working at the University of Sheffield for 1 year is exploring fertiliser impact, including the use of composted manure on environmental impacts.
Exploitation Route This project is developing decision support tools that use the critical zone approach. They are to guide better agricultural practices that have lower environmental impact. As we are encompassing a wide range of processes that occur in the critical zone, from the top of vegetation to groundwater, we are attempting to tackle previously neglected threats such as the deep leaching of nitrogen fertiliser to groundwater.

We provided a scientific foundation that can be accessed by the IT industry and others to develop simple tools that are accessible to a range of users from farmers to policy-makers. Our research also demonstrated the importance of incorporating human behaviour and drivers into understanding how critical zone processes are affected by land management.

Description Drawing on the results obtained in the first phase of the UK/China CZO projects, we developed tools to help make decisions that guide more sustainable farming practices in China. These included regional models and simpler Decision Support Tools that were underpinned by critical zone science. This brings in processes involved in landscape evolution, such as geochemistry, deep processes like nitrogen leaching and the impacts of different management practices. A major advance of our approach was bringing in economic impacts into the critical zone science approach. This used a natural capital approach to assess the economic implications of different management approaches, drawing on earlier research that used the underlying geology and its weathering to predict crop yields. We produced functioning decision support tools for the regions where our critical zone observatories are located. Moreover, we assessed over 400 existing decision support tools, but found that most were inappropriate because they were either too limited or geographically inappropriate for China. Only about a dozen existing DSTs were thought to be suitable for use in China. There was a gap, however, in decision support tools that incorporated both agricultural and economic impacts. Our research also explored the use of urban waste streams for fertiliser development. Nutrients are being mined from sewage and manufactured into a product that is not too dissimilar in appearance to conventional chemical fertiliser. There are concerns about pathogens and heavy metals that are being assessed further using advanced molecular biology techniques and plant biochemistry to assess pollutant uptake. Impact was hampered significantly by COVID-19 travel and working restrictions. Travel to China remained restricted from December 2019 (a few weeks after our last stakeholder event in China) until the end of the project so we were not able to conduct much of the impact work in China. We had hoped to travel to China before March 2022 when the project ended, but was not possible. Via the British Embassy Beijing and FASE, we were able to disseminate our research findings to over 2300 people in a webinar hosted in September 2022. Teams in China have pursued DST modelling with the critical zone data and adopted the approach developed in the project of incorporating a human element to get a broader, interdisciplinary understanding.

PI Contribution Jiangsu Academy of Agricultural Sciences (JAAS) developed a very helpful partnership with the MIDST-CZO project. They first participated in early interviews at the Stakeholder 1 workshops, where we asked about DST needs from farming and policy. From this initial exchange, we then developed a closer relationship for KE and research.
Collaborator Contribution Prof Yan Gao and her colleagues at JAAS helped to identify stakeholders in China who are relevant for DST development targeted at sustainable agricultural systems. We also drew on their own expertise of farmer engagement, where a range of tools including DSTs have been deployed. We used a large meeting hosted by JAAS for the Stakeholder 2 workshop. This provided greater access to stakeholders who were attracted to the meeting because of its broader objectives and value. We found getting interest from stakeholders to attend meetings focussed just on our project was difficult as it would require a large time commitment.

Results and Impact Soil structure as biological habitat is one of the themes of this ISMC Working Group, and will form the topic of our first webinar. We attracted a broad range of researchers, extending the reach of the ISMC to soil microbiologists and ecologists.

Soil structure forms the habitat of soil organisms and, thus, it is an obvious assumption that soil structure forms variably connected pore spaces and separated niches (i.e. habitats) that are of critical importance for the diversity of soil biota. This affects not only the genetic diversity of individual species, but more importantly the functional diversity within biological communities. Soil biology may also drive soil structure, possibly building favourable properties. The quantitative description of these interactions is weak, but a huge potential exists to learn more by exploiting new technologies and modelling.

What we learned:
1. About DSTs:
Many existing agricultural DSTs are available in China, including phone apps, WeChat public accounts and chat groups. Touch-screens are available in some villages to provide fertilisation guidance. These DSTs are mainly developed for precision agriculture or formulated fertilisers, focussing on fertiliser efficiency, rotation practice, or organic fertiliser usage to increase crop production.

Current gaps for these DSTs are: a) environmental impact not included but of great interest; b) there is a missing link between soil and water and c) no data from deep layers are used. CZO science and findings can contribute to all these gaps.

2. About stakeholders:
A major driver is the Chinese government aim for zero-growth in mineral fertiliser usage by 2020, coupled with enhanced environmental protection. Most stakeholders are interested in CZO science and data that probe soil and water processes to unprecedented depths. They see the assessment of environment impacts with the CZO approach provides considerable power in predicting non-point pollution, heavy metal risk and GHGs.

For both individual and large farming households, profit still comes as their priority. Improving crop quality has become one of their key considerations, closely related to the greater awareness from the public for better crops. As a result, there is increasing need amongst the farmers to reduce agricultural environmental pollution, particularly from heavy metals, to increase soil and water quality. An awareness of environment protection comes mainly from the large farming households. In addition, it was reported that farmers lack agreed methods of organic fertiliser application.

Many fertiliser companies are keen to collaborate with scientists and government for fertiliser-related agricultural management. With support from government to change from mineral to organic fertilisers, these companies are interested in effective fertiliser application (e.g. what fertilisers for what crops/plants and when to apply).

1. Overall summary

The meeting was attended by 300+ people comprising mainly applied agricultural scientists, with representation from government ministries (?5 people) and industry (?10 people). The aim of the meeting was to bring together experts in agricultural and environmental science in China for discussions on the prevention and control of agricultural non-point source pollution, farmland nutrient management, soil health, and biodiversity conservation. Notable guests included Academicians Prof. Fusuo Zhang, Prof. Zhaoliang Zhu and Prof. Yongguan Zhu. News reports from the meeting included: http://newzhs.jaas.ac.cn/show-1068-589-1.html (News report from JAAS) and http://jsnews.jschina.com.cn/shms/201911/t20191125_2430202.html (News report from Jiangsu net).

MIDST Co-hosted the "Symposium on the experience and problems of the efficient use of soil, fertiliser and water in the Yangtze River Economic Belt" along with the Station of Farmland Quality and Agricultural Environment Protection of Jiangsu Province (See appendix for agenda). Our interest in this meeting was to network with applied agricultural scientists in China who work more closely at the interface between science and farming than the Chinese collaborators on MIDST. JAAS are directly involved in the Peri-Urbon CZO, hosting field trials on the outskirts of Nanjing and providing expertise on agronomic performance of fertlisers derived from waste. We sought input from scientists and agricultural specialists on practical needs from Decision Support Tools (DSTs) targeted at improved agricultural and environmental performance. This was achieved through the hosting of this symposium and an exhibitor stand.

Our symposium had a number of very relevant talks for DST developments. There were 10 talks that covered new fertilisers, machinery, environmental concerns and farmer engagement. Dr Ying Zheng finished the talks in the session by providing an overview of the MIDST project, summarising the work of the UK-China CZO programme. The practical challenges and policy relevance of our research was emphasised by our invited speaker, Director Du Sen of the Ministry of Agriculture. All talks were in Mandarin to ensure full engagement of the Chinese audience. We followed the talks with an open panel session discussion which provided the floor with the opportunity to ask all speakers questions. This included a targeted discussion on research needs for DST development in China.

On Day 2 of the meeting, MIDST collaborator Prof Yongguan Zhu provided a talk that celebrated his very recent award as a CAS Academician. This was followed by another discussion forum on challenges facing agriculture and soils in China. Both Paul Hallett and Ying Zheng participated on stage to provide their insight and to guide questions towards DST development.

MIDST had an Exhibition Stand throughout the entirety of the event. This had an animation of one of our functional DSTs, computers running other DSTs that we have tested for application in China, and pamphlets in both English and Mandarin summarising the project and aimed at either users or researchers. There was considerable 1:1 discussion, reaching over 100 people. To enable guided discussion, questionairres were given to participants to ask about their knowledge, experience, perceptions and needs for DSTs. The MIDST post docs and 2 PhD students managed to get conference participants to complete 65 individuals.
