Replication Data for "Applying geospatial methods to assess and validate the uptake of fertilizer trees and fodder shrubs in Zambia"

"Accurately assessing the adoption or uptake of agroforestry, or other natural resource management practices at scale remains a challenge. Conventional survey methods such as structured household (HH) surveys are costly and hence sample sizes are often low, which in turn limits the extent to which one can reliably assess adoption of specific practices. Hence, alternative approaches for data collection are needed to conduct large-scale assessments of adoption. We explored the potential of geospatial methods, and in particular remote sensing, for mapping the distribution of Faidherbia albida in Zambia. More than 200 species of trees were identified during field surveys in late 2016 and from March to May 2017, with almost 90 different tree species occurring in agricultural fields. In other words, many of the farming systems surveyed had a high level of diversification in as far as tree species was concerned. Our study showed that farmers in Zambia tend to leave trees in their fields, or in some cases allow seedlings to naturally regenerate, generally favouring nitrogen fixing trees such as Faidherbia albida or Miombo species such as Brachystegia spp or Combretum molle."
