Patterns of Urbanization and Economic Development: Evidence from household surveys in Ethiopia
(2022-05-17)Countries in sub-Saharan Africa (SSA) are urbanizing at an unprecedentedly fast rate. This trend has the potential to affect the welfare of households by altering the degree of urban proximity as well as the size of the ... -
Cultivation and utilization of Hydrangea macrophylla subsp. serrata as feedstock for dihydroisocoumarins and its quality-assessment through non-invasive phenotyping
(2022-05-09)New and innovative bio-based products of today are regularly inspired by a long-known and traditional use of plants. One such example is the taste modifying phyllodulcin (PD), a dihydroisocoumarin (DHC) only present in ... -
Advances in technology evaluation and decision support studies using bio-economic farm models
(2022-04-11)The use of so-called bio-economic farm models makes it possible to determine the most cost-effective adaptation strategy to novel policy measures and to evaluate whether the use of new technologies can be economically ... -
The hidden risk of conventional floodplain mapping: Diagnosis in Cali, Colombia
(2022-04-05)Flood hazard maps display the geographical areas inundated by water bodies after extreme rainfall events take place, helping governments focus their efforts and resources on performing works to mitigate disasters produced ... -
Identification, characterisation, and evaluation of bioactive plant-based compounds for the sustainable stabilisation of food packaging materials
(2022-04-05)Typically, plastic packaging materials are produced using additives, like e.g. stabilisers, to introduce specific desired properties into the material or, in case of stabilisers, to prolong the shelf life of such packaging ... -
Yield, productivity and technical gaps that limit the cotton agricultural production system in the Colombian Caribbean
(2022-03-29)This thesis contributes to understanding factors related to production situations in agricultural systems of the Colombian Caribbean using decision analysis. Decision analysis has numerous advantages when it is used for ... -
Breeding progress for drought tolerance and nitrogen use efficiency in winter wheat (Triticum aestivum L.)
(2022-03-28)Drought is the major abiotic stress factor limiting agricultural production in arid, semi-arid as well as in temperate regions around the world, whereas nitrogen (N) is one of the most important nutrients for crop production. ... -
High-Throughput Phenotyping of Photosynthesis Traits in Durum Wheat Under Drought Stress Using Light-Induced Fluorescence Transients
(2022-03-24)Agriculture in the twenty-first century faces the double challenge of feeding a growing population in a changing climate. Food security will increasingly rely on the active release of stable high-yielding cultivars with ... -
Sustainability performance of organic and conventional farming systems in Kenya: Murang'a, Kirinyaga and Machakos Counties
(2022-03-17)The concept of sustainable farming systems focuses on the need to develop techniques and practices that have positive effects on social outcomes, the environment, and food productivity. In Africa, there are limited empirical ... -
Effects of different milk replacer feeding levels during a 14-week preweaning phase in heifer calves: Characterisation of the oxidative status and the mammary gland development by ultrasound imaging
(2022-03-15)The development of dairy heifer calves and especially their mammary glands is crucial for the productivity of the future dairy cows. Conventional rearing of dairy heifer calves is still based on restrictive milk or milk ... -
Modeling the spatial and temporal heterogeneity in malaria transmission and control in urban Ghana
(2022-03-03)In West Africa malaria is an endemic disease and a leading cause of mortality and morbidity. Over the years advances in mathematical modeling have improved understanding of the disease’s operational mechanisms. However, ... -
An environmental and economic assessment of a novel Power-to-Fuel system for biogas plants
(2022-03-02)Power-to-Fuel (PtF) systems use carbon dioxide and hydrogen as feedstock together for renewable fuel production and can hence contribute to climate change mitigation. This study tries to evaluate whether an innovative PtF ... -
Intergenerational Mobility and the Children of Migrants in Indonesia
(2022-02-23)Although there has been substantial increase in human development in Indonesia, individual inequality has not reduced significantly.
This dissertation focuses on intergenerational mobility and its interplay with ... -

Impacts of the expansion of aquaculture on global agricultural markets and land use change
(2022-02-14)Aquaculture is one of the most rapidly growing food producing sectors. It has the potential to meet future seafood demand from a growing global population. However, the expansion of aquaculture has led to a continuous ... -
Implications of topography and agronomic practices for soil biogeochemical and microbiological properties in Upper Eastern Ghana hilly farmland
(2022-02-10)While topography can infer erosion potential, implementation of convention practices can trigger accelerated erosion, and both pose major threats to soil abiotic properties and microbiota. The majority of farmlands in the ... -
Sensor-Based Phenotyping of Plant’s Physiological Responses to Abiotic Stress
(2022-02-03)Plant phenotyping can be defined as the systematic recording of morphological, anatomical, physiological and chemical characteristics of plants, as well as their developments and responses to stimuli. The common use of ... -
Decision analysis and hyperspectral imaging to support farmers in ornamental heather production
(2022-02-02)Ornamental Heather (Calluna vulgaris) is an important crop for the farmers of Germany’s Lower Rhine region. These farmers produce more than 78% of the ornamental heather in Germany. Successful production of this ... -
Large-scale mass redistribution in the Earth system from synergistic use of Swarm data
(2022-01-26)Long and consistent time series of large-scale mass redistribution in the Earth system are important in many scientific research areas. The dedicated Gravity Recovery And Climate Experiment (GRACE) and Gravity Recovery And ... -
Medical nutrition therapy in long-term adult intensive care patients: effects of protein quantity on muscle mass, biochemical markers, and clinical outcome
(2022-01-18)Research suggests that degradation of muscle mass and loss of functional proteins due to catabolism are associated with an adverse outcome in critically ill patients. While an adequate protein supply within a medical ...
