Conservation tillage in Kenya: the biophysical processes affecting its effectiveness
Maguta, Job Kihara (2009-07-14)Appropriate soil management is important for improved ecosystem functioning and high crop production. This study investigates how different tillage [reduced tillage (RT) and conventional tillage (CT)], crop residue (plus ... -
Consistently closing global and regional sea level budgets
Uebbing, Bernd (2022-11-17)Nowadays, human-induced climate change is the major driver of global and regional sea level change threatening the well-being and livelihoods of hundreds of millions of people living close to the coast. Consequently, ... -
Consumer acceptance of biotechnology: the influence of product end-use, policy context, and information framing
Butkowski, Olivier K. (2018-06-07)Consumer acceptance of novel technologies is a prerequisite for market adoption of the derived products. The transition towards a more sustainable bioeconomy in Europe requires product and process innovation that promotes ... -
Consumption Choices: The effects of food production, markets and preferences on diets in India
Ludwig, Till (2019-12-20)The choice of which food to consume is often an individual choice. Yet, food and nutrition insecurity presents a situation that those who suffer from it have rarely chosen consciously. Availability of foods, their accessibility ... -
Contract Standardisation as an Instrument for Access and Benefit-Sharing under the Convention on Biological Diversity: A Governance Analysis of Transactions with Genetic Resources
Täuber, Sabine (2011-07-15)Access to genetic resources and the fair and equitable sharing of benefits arising of their utilisation (short: ABS) is a central issue in the Convention on Biological Diversity. ABS is intended as mechanism to create ... -
The contribution of different fauna communities to improved soil health: A case of Zimbabwean soils under conservation agriculture
Nhamo, Nhamo (2007)For improved and sustainable soil productivity, the application of soil conserving cropping systems is important. This study characterizes soil fauna as a basis for comparing conservation agriculture and conventional ... -
Contributions to image-based high-throughput phenotyping in viticulture
Zabawa, Laura (2023-09-29)Grapevine is a crop with significant economic importance. Unlike many other crops, grapevine is a quality crop with the focus on yield optimization instead of maximization. Regular monitoring of plant diseases and pests ... -
Convex optimization for inequality constrained adjustment problems
Roese-Koerner, Lutz Rolf (2015)Whenever a certain function shall be minimized (e.g., a sum of squared residuals) or maximized (e.g., profit) optimization methods are applied. If in addition prior knowledge about some of the parameters can be expressed ... -

Coupled biotic-abiotic mechanisms of nitrous oxide production in soils during nitrification involving the reactive intermediates hydroxylamine and nitrite
Liu, Shurong (2017-11-22)Nitrous oxide (N<sub>2</sub>O) is an important greenhouse gas that can deplete the ozone layer. Microbial nitrification and denitrification have been long considered as the major contributors of soil N<sub>2</sub>O production. ... -
Coupled hydrogeophysical inversion for soil hydraulic property estimation from time-lapse geophysical data
Mboh, Cho Miltin (2012-12-21)Good knowledge of the hydraulic properties of the vadose zone is important for understanding water flow and solute transport processes therein. This can help to promote sustainable use and mitigate anthropogenic threats ... -
Coupling hydrological and irrigation schedule models for the management of surface and groundwater resources in Khorezm, Uzbekistan
Awan, Usman Khalid (2010-08-17)The irrigated agriculture in the Khorezm region of Uzbekistan is characterized by huge water withdrawals from the Amu Darya River. The vast infrastructure built for extensive irrigation, together with inappropriate drainage ... -
COVID-19 and changes in global agri-food trade
Engemann, Helena; Jafari, Yaghoob (2022-04-09)COVID-19 has raised questions about the resilience of agri-food trade to global shocks to the system. This paper analyses the changes in agri-food trade (values, extensive and intensive margin, and diversification) during ... -
Crop management options to reduce nitrogen pollution in Liangzihu lake basin, Central China
Zhang, Jin (2015-06-18)In Central China, high mineral nitrogen (N) application rates lead to low N recovery and high N losses. Large amounts of the nitrate-N leached from agricultural soil end up in aquatic ecosystems, which negatively affects ... -
Cross border crisis management concept: Establishing cooperation measures between Dutch and German veterinary authorities in animal disease control
Breuer, Oliver (2011-08-09)The objective of this thesis consisted in the development of cross border cooperation management in animal disease control. Particularly, the experiences and intentions of public and private stakeholders have been identified ... -
Cultivation and utilization of Hydrangea macrophylla subsp. serrata as feedstock for dihydroisocoumarins and its quality-assessment through non-invasive phenotyping
Moll, Marcel Dieter (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 ... -
