Robot Navigation Beyond Planning the Shortest Path
(2021-04-16)Over the last decade, the demand for autonomous mobile robots has been growing continuously. Applications range from mobile manipulators operating on factory floors to autonomous cars driving in urban environments. A common ... -
Sustainable intensification: Farmers’ adoption behaviour and environmental outcomes
(2021-04-06)Sustainable intensification measures imply implementing changes in farming systems to improve environmental outcomes without compromising economic outputs. In order to assess the achievement of these outcomes, the dissertation ... -
Armed Conflicts and Forced Displacements: Incentives and Consequences on Consumption and Social Preferences
(2021-04-06)Several countries currently have ongoing armed conflicts or are in post-conflict. Relatedly, the number of refugees has almost doubled in the last decade from continued armed conflicts with an increasing influx to countries ... -
Assessing and targeting management options for smallholder rice-based systems in Kilombero floodplain, Tanzania
(2021-04-06)In sub-Saharan Africa, agriculture contributes up to 50% of the GDP. The increase in agricultural output in the region is predominantly from area expansion instead of improvements in productivity per unit area. In the past, ... -
Characterization of mechanisms of resistance in Spodoptera frugiperda to synthetic insecticides and insecticidal proteins
(2021-03-18)Fall armyworm (FAW), Spodoptera frugiperda(J.E. Smith), is a major lepidopteran pest of maize in the American continent butitis now present in 107 countries worldwide. The control of FAW has relied mainly on the ... -
Quantitative modelling of the Rural Development Programs of the Common Agricultural Policy - EU-wide and region-specific effects
(2021-03-18)Rural Developments Programmes (RDPs) of EUs Common Agricultural Policy (CAP) are implemented to promote agricultural competitiveness, sustainable management of natural resources and climate protection, and a balanced ... -
Plant Classification Systems for Agricultural Robots
(2021-03-16)Due to a continually growing world population, the demand for food and energy increases continuously. As a central source of food, feed, and energy, crop production is therefore called upon to produce higher yields. To ... -
Price dynamics and interaction of international cash crop and staple food markets
(2021-03-08)For a number of net food importing developing countries (NFIDCs), abrupt changes in international staple food prices constitute an important source of macroeconomic instability. Theory suggests that in the face of instable ... -
Uranium accumulation in agricultural soils as derived from long-term phosphorus fertilizer applications
(2021-03-04)It is well known that uranium (U) in mineral phosphorus (P) fertilizers may accumulate in agricultural soils; yet, this U accumulation occurs at different rates, likely depending on the type of fertilizer used. To substantiate ... -
Options for sustainable agricultural intensification in maize mixed farming systems: explorative ex-ante assessment using multi-agent system simulation
(2021-02-17)Nutrient depletion is a major limiting factor to agricultural sustainability in cereal dominated smallholder farming systems in Africa where over 80% of arable land is unsuitable to support primary productivity. This ... -
Phenotyping of wheat resistance to Fusarium head blight using hyperspectral imaging
(2021-02-10)The integrated management of Fusarium head blight (FHB) on wheat depends on the implementation of agricultural practices, cultivation of resistant varieties, and fungicides application. Reducing yield losses and ... -
Phosphorus digestibility and metabolizable energy concentrations of contemporary cereal grain varieties fed to growing pigs
(2021-02-01)Cereal grains are a major feedstuff in pig nutrition across the world. Due to their high starch content and their high inclusion rates, they supply the majority of energy in diets for pigs. At the same time they also provide ... -
Algebraic, logical and stochastic reasoning for the automatic prediction of 3d building structures
(2021-01-26)3D building models are nowadays an important prerequisite for many applications such as rescue management or navigation tasks. However, most approaches for the automatic reconstruction of buildings rely on high-resolution ... -
Efficient calibration strategies for panoramic terrestrial laser scanners
(2021-01-25)Terrestrial laser scanner (TLS) measurements are unavoidably affected by systematic errors due to internal mechanical misalignments, while the calibration is the fundamental procedure for mitigating these effects and ... -
Clinically-relevant antibiotic-resistant bacteria in process waters and wastewater from poultry and pig slaughterhouses and assessment of the bacterial dissemination into surface waters
(2021-01-21)The objective of this thesis was the investigation of clinically-relevant antibiotic-resistant bacteria in process waters and wastewater from poultry and pig slaughterhouses and the assessment of the bacterial dissemination ... -

(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
(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
(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
(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
(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 ...
