(2023-09-08)This Ph.D. Dissertation explores smallholder preferences for contract farming options in the trade of vanilla from Madagascar. It seeks to identify possibilities to increase the mutual benefit of contract farming for both ... -
Challenges and Opportunities for Smallholder Farmers in Oil Palm Replanting: Evidence from Indonesia
(2025-02-14)The cultivation of oil palm supports the livelihoods of millions, including smallholder farmers. However, studies have shown that smallholder-managed plantations still generate much lower yields than large-scale company-managed ... -
Challenges of the Farmland Market: Essays on the Tension between Financialization and Regulation
(2024-01-18)In the recent decades, the German farmland marked faced enormous price increases. Those price increases caused intensive research. Among others, three streams of thought were especially in focus: farmland price ... -
Changing valuations of cultural ecosystem services along an urban-periurban gradient in Berlin
(2015-11-06)Urban green experiences high use-pressures through differing and conflicting demands. Eco-system services provided by urban green are manifold, with cultural ecosystem services (CES) representing socio-cultural benefits. ... -
Characterisation of genotypic and tissue specific resistance in oilseed rape (B. napus) against Sclerotinia sclerotiorum
(2020-01-03)Sclerotinia sclerotiorum is a necrotrophic ascomycete and the causal agent of stem rot disease, an economically important constraint in the cultivation of oilseed rape (Brassica napus L.). Since cultivar resistance is a ... -
Characterisation of organic cereals and grain legumes as feedstuffs for monogastric animals: Effects of variety and environmental conditions on the contents of crude nutrients, amino acids, thiamine, riboflavin, and in vitro digestibility of crude protein and amino acids
(2019-05-10)The sufficient supply of nutrients, in particular of protein and amino acids, for monogastric animals in organic farming is challenging. For one thing, some feedstuffs that are rich in crude protein and contain large ... -
Characterization of Leptosphaeria maculans races in Germany and studies on resistance of Brassica napus to blackleg disease
(2023-03-23)Leptosphaeria maculans, a phytopathogen causes blackleg disease, is an economically significant biotic stress that affects oilseed rape (B. napus) production worldwide. Blackleg disease can be controlled by stubble management, ... -
Characterization of novel sources of resistance to Phytophthora infestans (late blight) in organic fresh market tomato
(2019-10-21)Tomato (Lycopersicon esculentum) is the most widely grown vegetable food crop in the world. Late blight (LB) caused by Phytophthora infestans (Mont.) de Bary is a major cause of crop loss in tomato and potato around the ... -
Characterization of plant-based alternative products with consideration of qualitative and nutritional aspects
(2022-10-19)One of the greatest challenges of the 21st century is to meet the food needs of a growing world population without exceeding the planetary boundaries. The consumption and production of food products of animal-based origin ... -
Characterization of α-amylase in wheat and maize
(2016-04-11)Alpha-amylase is a starch-hydrolyzing enzyme and its characterization is an important quality parameter in cereal grains. In breadmaking, adequate α-amylase activity is required to produce bread of good quality. High ... -
