The roles of nutrition-sensitive interventions and market access in enhancing household food security and resilience in Sierra Leone
(2021-05-17)
Using Sierra Leone – a post-conflict country in West Africa – as a case study, this dissertation addresses pressing issues on how to make smallholder agriculture more nutrition-sensitive, mitigate the adverse effects of ...
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 ...
Adaptation strategies to climate change in inland valleys in Dano, Burkina Faso
(2021-06-16)
The agriculture in Sub Saharan Africa at many locations is under-performing and lags behind the other continents in terms of yields as well as productivity. The recent progression in the produced quantities is mainly due ...
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 ...
Development of a one-step 3D approach for the phase unwrapping process in a D-InSAR stack based on SBAS interferograms
(2020)
Differential Interferometric Synthetic Aperture Radar (D-InSAR) is a unique technique to detect and map deformations of the Earth's surface over large temporal and spatial scales. Processing a whole stack of multitemporal ...
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 ...
Robot mapping and navigation in real-world environments
(2020)
Robots can perform various tasks, such as mapping hazardous sites, taking part in search-and-rescue scenarios, or delivering goods and people. Robots operating in the real world face many challenges on the way to the ...
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 ...
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 ...
Concepts for the assessment and improvement of animal welfare during stressful and painful management procedures with a focus on piglet castration
(2021-09-06)
The welfare of farm animals is a topic of rising importance to consumers and livestock owners. Many procedures that are routinely performed in young livestock, for example the surgical castration of piglets, are considered ...
