Abstract:
TARI is a leading research institution in Tanzania that is dedicated to promoting sustainable agricultural development and improving agricultural productivity. Established in 2016, TARI is the national agricultural research organization responsible for generating and disseminating scientific knowledge and innovative agricultural technologies.
As part of this mandate, TARI collaborated together with Varda and other players in a feasibility study to implement a large-scale liming program to enhance the productivity of acidic soils in Tanzania and boost soil health. Within this project they have provided a soil dataset that was used for modelling purposes. The data were cleaned,processed and transformed into Shapefile format for spatial analysis. Following this, we harmonized the data in terms of vocabulary and unit of measurement. During the harmonization process, certain parameters were excluded from the dataset as they were not necessary for the modeling activities.
More information on the data lineage can be provided under request.
