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…

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.

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.

Guizhou Karst area knowledge exchange report

A Knowledge Exchange survey and interview research was carried out in Guizhou’s karst area. This research sought to understand the current ways in which Chinese leaders and farmers learn from scientists and what are key issues facing them that the red soil CZ research can help with. This report documents the findings of the needs of local farmers, their farming practices and understanding of landscape processes, along with learning preferences of different public groups (farmers and village, town and country leaders). An English copy of the report can be found (Guizhou Report) or from the OSF project page here. A Chinese copy…

Jiangxi’s red soil Knowledge Exchange report

Following on the early stage of exploration in Guizhou’s karst area (Guizhou report), similar KE survey and interview research was carried out in Jiangxi’s red soil landscape in March 2018. This research sought to understand the current ways in which Chinese leaders and farmers learn from scientists and what are key issues facing them that the red soil CZ research can help with. This report documents the findings of the needs of local farmers, their farming practices and understanding of landscape processes, along with learning preferences of different public groups (farmers and village, town and country leaders).

Summary Report of China – UK Knowledge Exchange Project.

Supplementary funding was gained to add a knowledge exchange component to the UK-China Critical zone programme. This study explores what knowledge transfer and knowledge exchange activities can facilitate communication and understanding between academics and the non-academic groups in these CZ research area in the context of Chinese culture, especially in Chinese rural areas. “With two-years research, better understanding has been developed of the Knowledge Exchange dynamic and science-policy-practice interface in China rural areas. Now this gained understanding can allow us to consider the existing pathway to impacts of each Critical Zone project and make suggestions of amendments which may make these…
