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 ... -
Exploring behavioral motivations as drivers for the adoption of bio-economy innovations
(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 ... -
Synthese und Charakterisierung von funktionalen Lignin-basierten Polyurethan-Coatings aus unmodifiziertem und modifiziertem Kraft-Lignin
(2020-12-02)Bedingt durch die zunehmende Rohstoffknappheit rückt die Suche nach alternativen, nachhaltigen Rohstoffen immer mehr in den Vordergrund. Im Hinblick auf effiziente chemische Verwertbarkeit bietet Lignin zahlreiche Vorteile ... -
Diagnosing and managing zinc and boron deficiencies in emerging crop production systems of Nepal
(2020-12-02)The productivity and sustainability of the prevailing crop production systems are being challenged throughout the Indo-Gangetic Plains. Limiting water resources, depletion of soil fertility, social changes and economic ... -
Sapling ecology and management in multi-species afforestation system on degraded cropland in the Sudano-Sahelian zone of Benin
(2020-12-01)Sub-Saharan Africa faces the multiple challenges of improving food security of the rapidly growing human population while halting the severe land degradation and coping with climate change impacts. Re- and afforestation ... -
Exhaust air treatment systems for the mitigation of dust, ammonia and odour from poultry housing
(2020-11-26)Exhaust air treatment is becoming increasingly important in poultry husbandry with a rising number of animals kept per barn. An adaptation of the systems that already have been successfully used in pig husbandry only works ... -
Empowerment of Girls and Women in Rural Pakistan: Migration, Decision-making and Consciousness
(2020-11-24)This thesis analyses the effect of migration of men on women and children left behind in rural households in Pakistan. Part one analyses the impact on left-behind women’s participation in household decisions and number of ... -
Iron isotope fractionation in arable soil and graminaceous crops
(2020-11-24)Soils contain large quantities of Fe, however, the Fe-solubility is very low. Plants have developed two efficient strategies to secure Fe uptake from soil under Fe-deficient conditions: (i) the sequential acidification-r ... -
The role of post-harvest supplementary light exposure for ripening and quality development of tomato fruit
(2020-11-23)The major aim of the present work was to evaluate the optimal exposure time and effects of red light and short periods of daily ultraviolet (UV) on the post-harvest quality of green tomato fruit during ripening. The ... -
Root-restricting layers in German agricultural soils: Extent, cause and management strategies
(2020-10-21)Subsoil, i.e., soil below 30 cm depth, harbours great amounts of water and nutrients. However, physical and chemical barriers for vertical root elongation may restrict plants from accessing subsoil resources. Such ... -
Characterization of Root System Architectures from Field Root Sampling Methods
(2020-10-21)Background and objectives: The root system architecture (RSA) of a plant determines the plant’s ability to capture resources efficiently from the soil and directly linked to plant performance. The development ... -
