Heinz, Erik Edmund (2021-01-20)In den letzten Jahren hat die Nutzung von Multisensorsystemen für kinematisches Laserscanning zunehmend an Bedeutung gewonnen. Dies zeigt sich durch die wachsende Anzahl am Markt verfügbarer Systeme und die sich ... -
Towards bamboo-agroforestry development in Ghana: exploring socio-economic and ecological potentials
Akoto Sarfo, Daniel (2021-01-14)In Ghana, the rising need for household energy from wood fuels and food needs is considered a major threat to forest resources conservation. Government and scientists believe that the alarming rate of deforestation and ... -
Economic disruptions, markets and food security
Kankwamba, Henry (2020-12-30)Idiosyncratic and covariate shocks have considerable impacts on household food security and welfare. While impacts of covariate and idiosyncratic shocks have been widely documented, the mitigating role of infrastructure ... -
Exact Optimization Algorithms for the Aggregation of Spatial Data
Oehrlein, Johannes (2020-12-16)The aggregation of spatial data is a recurring problem in geoinformation science. Aggregating data means subsuming multiple pieces of information into a less complex representation. It is pursued for various reasons, like ... -
Hyperspectral in-field sensing of foliar diseases of wheat
Bohnenkamp, David (2020-12-10)The major aim of this work was to prove the suitability of hyperspectral sensors for the detection of foliar diseases of wheat under field conditions. Hyperspectral sensors, measurement protocols and analysis methods were ... -
Exploring behavioral motivations as drivers for the adoption of bio-economy innovations
Wensing, Joana (2020-12-10)For the past centuries, fossil resources served the German economy as the basis for numerous technological innovations facilitating continuous economic growth and prosperity. However, global challenges of the 21st ... -
