Item Open Access Evidence review of smallholder adaptation to climate change(Cranfield University, 2021-10-25 09:14) Knox, JerryThe aim of this IFAD funded systematic review was to assess the extent to which learning outcomes have supported initiatives to mainstream adaptation for smallholder agriculture, focussing on three key areas, (i) scaling up climate sensitive adaptive interventions, (ii) the role of knowledge management to promote effective adaptive solutions, and (iii) human-ecosystem interactions in climate change adaptation. The dataset provides a summary of the evidence identified as part of the bibliographic searches and the analyses that were then conducted on the screened data.Item Open Access Soil Testing Data and ArcGIS files for "An analysis of in-field soil testing and mapping for improving fertiliser decision-making in vegetable production in Kenya and Ghana"(Cranfield University, 2022-02-17 08:46) Mallory, Adrian; Golicz, Karolina; Sakrabani, RubenIn-field soil testing and soil mapping can contribute to addressing the challenge of poor soil fertility and limited fertilizer application across sub-Saharan Africa. Semi-quantitative colorimetric methods, such as paper test strips, are frequently employed in soil nutrient assessment across developing countries, especially in South-East Asia. This research investigated the accuracy of nutrient-sensitive paper strips and smartphone, which was re-purposed to act as a reflectometer, to assess soil nitrate-N, and different methods for mapping soil fertility to identify areas of land that are suitable for human waste-derived fertilizers (HWDF) application. The study entailed testing soil samples across 42 different farms in Kenya and Ghana and compared it to laboratory results in-country. It was found that paper strips were capable of assessing available nitrate-N concentration present in the soil within ±20 kg ha−1 of the stand-ard method for 86% of the farms. Paper strips were less effective in Ghana as they had been calibrated for a method that was not used by local laboratories. Paper strips were not effective for HWDF samples, where chemical interferences and concentra-tion of different forms of nitrates were too high, resulting in overestimation of read-ings and thus negatively affecting any associated nutrient management advice. Soil mapping has the potential to use open-source data to inform farmers through mobile technology. For soil mapping two methods were deployed which includes targeting organic matter deficient areas and stakeholder led mapping, with the latter shown to be more effective in identifying areas for HWDF application.Item Open Access Strengthening Thailand's Agricultural drought Resilience -Questionnaire and Dataset(Cranfield University, 2021-09-01 13:43) Goodwin, Daniel; Holman, Ian; Sutcliffe, Chloe; Rey Vicario, DoloresRecords of interviews with farmers in the Ping Catchment, Thailand as part of the STAR project. Interviews were undertaken in January 2020. A copy of the questionnaire is also provided.
