Animal health and genetics—Issues and controversies for ILRI research by International Livestock Research Institute

“…4) How do we more effectively translate the 'blue sky' research into messages for farmers and technologies that value chain actors can understand and apply? 5) How do we 'ground truth' blue sky investments - that is critical to continue needed productivity growth into the future - into shorter-horizon research to support 'value chain' work? …”

The enviro-champs: establishing a framework for a technologically upgraded environmental monitoring network at community scale by Pattinson, N. B., Taylor, J., Lepheana, A. T., Dickens, Chris W. S., Graham, P. M.

“…However, several areas within the initiative remain where it could be improved, especially technologically. GroundTruth, in conjunction with technical and funding support from CGIAR Research Initiative on Digital Innovation and the International Water Management Institute (IWMI), engaged in a project which aimed to i) establish recruitment, training, and education tools to support establishment of a technologically integrated and upgraded Enviro-Champs initiative, ii) develop an outline for a training and education workshop for Enviro-Champs once they are hired, iii) improve data collection and reporting capacity and efficiency with a sustainable system (in collaboration with CGIAR and FormShare), and iv) pilot test technological improvements to the Enviro-Champs initiative within the Mpophomeni Enviro-Champs in conjunction with the South African National Biodiversity Institute (SANBI), and Umgeni Water. …”

Improving the accuracy of remotely sensed irrigated areas using post-classification enhancement through UAV [Unmanned Aerial Vehicle] capability by Nhamo, Luxon, Dijk, R. van, Magidi, J., Wiberg, David A., Tshikolomo, K.

“…The normalized difference vegetation index (NDVI) applied on Landsat imageries on the mapped fields during the dry season (July to August) was used to identify irrigated areas, because years of satellite data analysis suggest that healthy crop conditions during dry seasons are only possible with irrigation. Ground truth points totaling 137 were collected during fieldwork for pre-processing and accuracy assessment. …”

Varbergs Societetspark 1856 - 2008 : en promenadparks förvandling by Gustavsson, Kristina

“…There was already a health resort park of this kind in Varberg,the Brunnsparken, but it had to close down because it was to small and could not compete with the Societetsparken. To tell the truth, Societetsparken was little of a fake because it did not have its own well.The owners had to deliver water from another well, also a famous place, called Svartekällan(The Black Well), south of Varberg, where the tradition of drinking healthy water started in 1811 when the well with its excellent water was first discovered. …”

Assessment of land degradation in semi-arid Tanzania: Using remote sensing to inform the Sustainable Development Goal 15.3 by Reith, J.A.
