The effect of information provision on attitude, intention, and food choice behaviour: Four experimental studies
(2023-05-09)The agricultural and food sector in Germany is facing a number of challenges. Consumers are increasingly dissatisfied with contemporary livestock production and, in addition, livestock farming accounts for a substantial ... -
The governance of plant breeding - a social-ecological systems perspective
(2023-04-13)Climate change and social conflicts put modern agricultural systems under pressure, necessitating systemic transformations of these systems towards sustainability. At the core of these sustainability challenges to agriculture ... -
Nutrient elements in micro- to nanosized fractions: occurrence, transport, and plant uptake in agroecosystems
(2023-04-04)As phosphorus (P) is a non-substitutable nutrient for all organisms and thus pivotal in supporting crop productivity, limited and unevenly distributed phosphate rocks drive research concerns on substituted P fertilizers ... -
Drinking behaviour of llamas (Lama glama) and horses (Equus caballus) in response to saline drinking water
(2023-03-24)Saline drinking water can play an important role in the nutrition of domestic animals, either through the salinization of natural drinking water sources or the intentional application as part of rehydration therapy after ... -
Identification and functional characterization of ENHANCED GRAVITROPISM 2 controlling the root setpoint angle in barley (Hordeum vulgare L.)
(2023-03-15)Root gravitropism allows plant roots to penetrate deep into the soil and is one of the main factors determining the root setpoint angle. Understanding the molecular mechanisms underlying the root setpoint angle of crop ... -
Technology adoption and upscaling of detailed farm-level models
(2023-03-06)Adoption of digital farming technology can be an important driver for agricultural productivity enhancement and transformation towards a sustainable farming system. Thus, understanding farmers’ technology adoption decisions ... -
Urban Flood Resilience: From Benchmarking Resilience to Accelerating Transformation Using Crowdsourcing Data
(2023-02-23)This thesis represents a significant contribution to the field of disaster resilience in the context of flood hazards in Iran and Germany. In the face of increasingly unpredictable climate-related extreme events, it is ... -
Improving children’s environmental health in Metro Manila, Philippines, through a school water, sanitation, and hygiene intervention
(2023-02-15)Millions of children are exposed to inadequate water, sanitation, and hygiene (WaSH) in schools globally. Diarrhoea is a leading cause of disease, while dehydration impairs cognitive performance and malnutrition hinders ... -
Challenges related to statistical methods and sensor systems for the daily prediction of health disorders in individual dairy cows
(2023-02-02)The use of digital support systems has become a standard in dairy farming, and significant effort has been made to detect individual animals that are in need for a treatment by using sensor data. However, developing systems ... -
Development of root phenotyping methods and QTL analysis of root traits in grapevine mapping populations
(2023-01-30)Facing climatic change and upcoming extreme weather events require the adaptation of agricultural crops to conditions like extended drought periods in the future. Therefore, the incorporation of promising morphological and ... -
The effectiveness and efficiency of forest conservation policies to reduce deforestation in the Peruvian Amazon
(2023-01-23)Between 2015 and 2020, 9.3 million hectares of tropical forests were annually deforested. Deforestation represents the second largest source of carbon emissions globally, reduces biodiversity and ecosystem services, and ... -
UAV remote sensing for the spatial differentiated assessment of plant traits based on multispectral images
(2023-01-09)Rising global temperatures, carbon dioxide (CO<sub>2</sub>) concentration, and the occurrence of extreme weather events are constantly changing the environmental conditions for crop productivity. Identifying climate-adapted ... -
Health and Welfare Implications of Climate Variability: Evidence from Rural Uganda
(2022-12-20)Uganda has been highly affected by extreme weather events and climate change in the recent years. Weather-related disasters could potentially affect health outcomes directly, or indirectly through its deleterious effects ... -
Heavy metal contamination in urban agriculture and human health risk in Yaoundé, Cameroon
(2022-12-14)Heavy metals are ubiquitous in the environment. The sources of heavy metals are both natural and anthropogenic activities. Urban growth, coupled with increasing demand for vegetables, has led to the utilization of lowlands ... -
Functional characterization of the maize (Zea mays L.) lateral rootless 1 gene
(2022-12-14)All root types form lateral roots. They are critical for efficient water and nutrient uptake by increasing the absorbing surface of the root system. In the maize differentiation zone, pericycle and endodermis cells adjacent ... -
Soviet tractors vs. oxen: agroecology, agricultural policies and political discourse in Cuba
(2022-12-07)After the collapse of the socialist bloc in the late 1980s and early 1990s, the Cuban government was forced to forsake its plans to develop a modern agricultural sector, highly dependent on the intensive use of imported ... -
Influence of dietary concentrations of L-histidine, alone or in interaction with β-alanine, on breast meat quality and metabolic status of modern, fast-growing broiler chickens
(2022-12-06)An increasing demand for poultry meat resulted in optimization of broiler chicken’s genetic towards high growth-rates and breast yield in the last decades. This breeding standard led to increased quality problems in breast ... -
Genetic analysis of drought stress adaptation in bread wheat diversity
(2022-12-06)The accumulations of proline (Pro) and hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) are the typical response of plant against drought stress, therefore genetic analysis of these responses are crucial to establishing new ... -
Options to improve irrigation efficiency and productivity under rotational delivery schedule, a bottom-up approach applied at canal irrigation scheme in Pakistan
(2022-12-06)In Punjab, Pakistan, the Warabandi principle guides the distribution of surface water over a network of canals providing farmers with limited water in proportion to land size in a fixed 7-days rotation. Current problems ... -
