Contract Farming in Developing Countries - A Behavioral Perspective on Contract Choice and Compliance
(2017-11-09)Although there is a lot of evidence for the positive welfare effects of contract farming, it is not clear how to integrate farmers into contracts and how to maintain stable long-term-relationships between farmers and ... -
Contract Farming in Vietnam: Empirical Research on Marketing Determinants, Farm Performance and Technical Efficiency of the Export-oriented Rice Sector in the Mekong River Delta
(2019-01-25)Better market linkages and higher farm benefits for smallholder farmers in emerging and developing economies have received remarkable attention worldwide (Minot and Roy, 2007; Kumar et al., 2011). In this regard, contract ... -
Control of estrous cycle and superovulation in goats
(2020-05-27)Summary Estrous cycle control is a widely used reproductive biotechnology for controlled breeding of small ruminants. Besides serving the purpose of synchronizing estrus, so that breeding takes place at a particular time, ... -
CONTROL OF REPRODUCTION IN NILE TILAPIA (OREOCHROMIS NILOTICUS) BY MANIPULATION OF ENVIRONMENTAL FACTORS
(2010-06-11)The aim of the study was to determine which holding conditions are most propitious in inducing the greatest number of breeders to spawn within an interval of 5 days. The spawning frequency ... -
Controlling of dairy cattle breeding programs
(2012-01-16)The overall goal of this study was to develop possible controlling approaches for dairy cattle breeding programs. For this reason different topics from practical dairy cattle breeding were ... -
Cost-effective priority areas for the conservation of the Maulino coastal forest and Cost-effectiveness gains by considering climate change effects in reserve network planning of Nothofagus alessandrii (Ruil)
(2019-11-08)The most common vegetation in the Maule region of central Chile is sclerophyllous forest. The microclimate weather on the west oriented hillsides of the coastal range of the Maule region, however, allows the occurrence of ... -
Critical Factors of Post-Harvest Nitrous Oxide Emissions from Oilseed Rape – Cereal Rotations
(2020-05-06)The sub-project of the project “Minderung von Treibhausgasemissionen im Rapsanbau unter besonderer Berücksichtigung der Stickstoffdüngung” of the division Plant Nutrition and Crop Physiology, Department of Crop Sciences ... -
Crop residue decomposition and stabilization in soil organic matter
(2017-02-10)Cropland soils may be sources or sinks for atmospheric CO2. In general, it is assumed that C input into the soil and soil organic matter (SOM) levels are linearly related. This gives rise to environmental concerns regarding ... -
Crop rotational effects on soil structure, root development and yield formation of winter wheat
(2025-02-14)Winter wheat (Triticum aestivum L.) is one of the most important staple food crops worldwide and commonly grown in crop rotations to obtain high grain yields and overcome increased disease pressure which is caused by ... -
Customer Engagement in the German Wine Industry
(2020-02-06)Over the last decade, customers have become more interactive and networked. This is mainly due to the rise of social media allowing customers to exchange almost anytime. In this vein, the new field of customer engagement ... -
Deciphering the genetic background of quantitative traits using machine learning and bioinformatics frameworks
(2021-10-08)In this thesis, I developed two frameworks that can help highlight the genetic mechanisms underlying quantitative traits. In this regard, my focus was to design efficient methodologies to discover genotype-phenotype ... -
Deciphering the genetics of pig complex traits through QTL mapping and positional candidate cloing
(2007-02-12)Most traits in livestock are controlled by multiple genes and are therefore called genetically complex traits. In this thesis, we firstly report the molecular characterization and evaluation ... -
Deciphering the molecular mechanisms underlying complex traits using bioinformatics and computational biology approaches
(2022-12-06)With the advent of high-throughput sequencing technologies, multi omics studies (genomics, transcriptomics, proteomics, and metabolomics) are becoming increasingly popular to decipher the molecular patterns in association ... -
Decision Making under Uncertainty in Developed and Developing Countries: An Experimental Analysis of Farmers’ Risk Attitude and Investment Behavior
(2014-06-18)The papers of the dissertation focus on decision making under uncertainty of farmers in developed and developing countries and apply experimental approaches in order to investigate farmers’ risk attitude and investment ... -

(2018-02-01)This cumulative dissertation discusses a range of topics related to the demand for and considerations around product design of weather index insurance instruments aimed at smallholder farmers’ risk management. The second ... -
Demand for Irrigation Water from Depleting Groundwater Resources: An Econometric Approach
(2012-12-18)This dissertation is divided to three essays that summarise groundwater demand studies in pistachio production of the Rafsanjan aquifer in southeastern Iran from three different methodological approaches. It is said that ... -
Demand for Processed Indigenous Fruit and Vegetable Products – Insights from East Africa
(2022-06-24)There is an increasing understanding that food systems need to provide not only calories but micronutrients as well. Simultaneously, consumption patterns are transforming around the globe. Convenience foods that are quick ... -
Designing incentive mechanisms for sustainable land management: evidence from Indonesia
(2015-08-12)Over the last five decades, the growing demand for ecosystem services, such as food, water and fuel has led to the most rapid and extensive changes in ecosystems in human history. Examples for these transformations include ... -
Designing politically feasible policies to enhance healthy and sustainable diets – empirical insights.
(2025-01-07)The adoption of nutrition policy measures to promote healthy and sustainable diets has lagged behind the health, environmental, social, and economic arguments to invest. In recognition of the fact that a lack of political ... -
