Modelling the dynamics of land use & intensification in the Kilombero Valley, Tanzania
(2021-06-17)This thesis intends to examine the determinants and results of farmer’s decisions to uptake different paths of intensification, land use, and its dynamics over time by building a spatially and temporally explicit agent-based ... -
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 ... -
Economic and policy mechanisms affecting land use decisions in the Brazilian agricultural frontier
(2021-06-16)The sustainable use of land resources is one of the most complex challenges facing the 21st century. As Brazil is one of the countries most endowed with land resources, it can facilitate global food and energy demands while ... -
Spatio-Temporal Registration Techniques for Agricultural Robots
(2021-06-16)A critical challenge that we face today is to meet the rising demand for food, feed, fiber, and fuel from an ever-growing world population. We must meet this demand within the limited arable land available to us and do so ... -
Potential and limitations for the practical use of fluorescence sensors to detect physiological adaptations of crops
(2021-06-14)The key objective of the present work was to evaluate the potential and limitations for the practical use of fluorescence sensors to detect physiological responses of crops to abiotic stresses, and the crop adaptations to ... -
Genomic indicators for boar taint and fertility in Landrace and Large White populations
(2021-06-14)Castration of male piglets in their first week of life is a commonly used but critically reflected method to avoid boar taint. Fattening of entire males represents a long-term sustainable alternative to castration but ... -
From lab to field - investigations of phosphorus availability from sugarcane bagasse ash to soybeans
(2021-05-26)Every year the Brazilian sugarcane industry generates up to 10 million tons (dry matter) of ash from the combustion of sugarcane bagasse, which is a fibrous plant material that remains after sugarcane juice extraction. ... -
Dormancy in temperate fruit trees - Perspectives for farming in a changing climate
(2021-05-26)Deciduous fruit trees, which originated in temperate climates, exhibit an inactive period (i.e. dormancy) between late autumn and early spring. This period allows trees to endure the severe winter temperatures usually ... -
Effect of an inflammatory stimulus on mitochondrial functionality in liver cells of dairy cows
(2021-05-26)Mitochondria are essential organelles with key roles in metabolism and health; their function is influenced by various exogenous and endogenous factors. Dairy cows undergo a negative energy balance (EB) and a systemic ... -
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 ... -
Anbauoptimierung durch Mischanbau und inhaltsstoffliche sowie sensorische Qualitätseigenschaften morphinarmer Winter- und Sommermohnsorten (Papaver somniferum L.)
(2021-05-04)Der Anbau und die Vermarktung von Mohnsamen aus regionalem Anbau bieten Chancen, eine alte Kulturpflanze in moderne Agrarökosysteme und Betriebskonzepte zu integrieren und diese ökologisch wie ökonomisch aufzuwerten. ... -
