Extreme weather events in Sudan Savanna Region of West Africa: agricultural impacts and adaptation
(2019-11-14)Climate and weather extremes generally lead to crop yield, income and consumption losses. Despite their occurrence at the farm level, very little has so far been done to empirically assess weather risks and their effects ... -
Root and shoot phenotypic traits and their expression in response to sowing density in spring barley (Hordeum vulgare)
(2019-11-12)Much is known about plant performance under controlled conditions and much about performance under field conditions as well as on single plants and populations. The extent, however, to which the variability of traits, ... -
Gender roles in Agriculture and natural resources management in upper east region, Ghana
(2019-11-08)The Upper East region is one of the poorest regions in Ghana with an estimated 90% of the people living in rural areas being peasant farmers. In many instances, farmers use their land unsustainably thus worsening the already ... -
Assessing technology transfer in the interdisciplinary research setting of the bioeconomy: A concise study using disciplinary, stakeholder and technology perspectives
(2019-11-25)Technology transfer from academia to industry in emerging knowledge areas such as the bioeconomy is considered a major challenge. In this regard, there have been an increasing number of policy and funding initiatives (e.g. ... -
The role of production method and country-of-origin labelling in consumers' food choice: Empirical study based on meta-analyses and stated preference choice experiments
(2019-10-24)Organic production and domestic origin of food serve for consumers as extrinsic cues for food safety and food quality dimensions. With consumers' growing interest in food quality and their increasing concern regarding food ... -
The revision of the German Fertilization Ordinance in 2017: Analyzing economic and environmental impacts at farm-level
(2019-10-31)The Fertilization Ordinance (FO), implementing the EU Nitrates Directive in Germany, is the core regulation to limit the loss of reactive nitrogen and phosphorus from agriculture. It was revised in June 2017 after environmental ... -
Understanding food technology evaluation across supply chain actors: A methodological and empirical analysis
(2019-10-12)World development trends such as increasing world population, climate change, urbanization, malnutrition, food waste and losses as well as resource scarcity are challenging the global food system. To address these challenges, ... -
Visual Place Recognition in Changing Environments
(2019-10-10)Localization is an essential capability of mobile robots and place recognition is an important component of localization. Only having precise localization, robots can reliably plan, navigate and understand the environment ... -
The role of Rboh-mediated ROS and glutathione in plant-nematode interaction
(2019-11-05)Aerobic life forms are known for constant production of reactive oxygen species (ROS), the deleterious end-products of aerobic energy that are able to provoke cellular damage. The ROS production in plants can be triggered ... -
