| Description of PhD-Topic | Applied Method: His PhD aims at a regional impact assessment of pesticides risk at the level of Germany. For this the three models RAUMSI, ISPS and NEPTUN have been applied. Three results of risk potentials, GIS surface water body data and production data has been linked to a risk indicator on pesticide leaching. Expected result: A regional assessment of risk potentials for pesticide leaching as a policy information tool that support decision making at regional level. Different scenarios will help to define the decision room depending on the policy instrument buffer zone programme. Final recommendations on different alternatives of analysed environmental programmes will be made. |

| Description of PhD-Topic | Applied Method: My PhD thesis is focussing on rural bioenergy provision in Tanzania. We collected data in a village survey in Laela/Rukwa region in Western Tanzania. The focus is on (1) rural biofuel production potential for decentralised electrification, (2) the potential impact of improved woodfuel stoves and (3) the potential impact of improved charcoal kilns. Expected result: The energy challenge is crucial for food security and the forest resources for the supply of woodfuels (esp. charcoal and firewood) are declining rapidly in the case study village and beyond. Efficient cook stoves and efficient charcoal kilns can lower the pressure. |

| Description of PhD-Topic | Applied Method: The PhD's goal is to formulate an optimising model for the renewable energy hybrid system involving anaerobic digestion of animal wastes (nutrient cycling), wind and solar energy harnessing for smallholder farmers and households in Chamwino-Dodoma. All major components of the system will be assessed by use of available research writings, models (like MATLAB, HOMER, CFD etc.) and other appropriate assessment tools as well as conducting relevant experiments. The results will be used for building an optimising model for the above mentioned system. Expected result: The optimising model for renewable energy hybrid system as policy and technical tool for enhancing informed decision making at all levels of operation and management of renewable energy subsector and environment at large. Wide-spread adoption of system/technology to the energy and soil-nutrients needy smallholder farmers in pro-poor and some poorly grid-connected areas , may be boosted through application of the model. |

| Description of PhD-Topic | Applied Method: Mwinuka will examine productivity and welfare effects of fertilizer micro-dosing (MD) for upgrading the Maize and Millet value chains in Morogoro and Dodoma, Tanzania. His study assumes that, feasible value chain upgrading strategies such as fertilizer MD are vital for creating a quick-win situation for farmers and other agents in the commodity market. A total of three hypotheses will be tested related to productivity, economic surplus and adoption rate for both sub-humid and semi-arid conditions. Expected result: apart from other things and through an economic evaluation, his study will systematically prove or refute the claim that fertilizer micro-dosing may or may not be a profitable practice given labour intensity of localized application. Due to food systems diversity, success stories of the technology from case study sites would easily be disseminated to other regions within the country. |

| Description of PhD-Topic | Applied Method: The PhD study is set to find out efficiency potentials for commercializing and trading in the agri-food sector, connecting supply and demand centres. How increased agricultural production will not result in declined prices but increased income? How adoption, productivity and market development can go at par? What can be done to increase market size and access to small-scale producers? The study will outline how to shape policies and institutions such that they support commercialization pathways for Agricultural food systems. Expected result: Smallholder agriculture commercialization levels, market integration (Status and levels) and correction mechanisms will be established. The study will review policies and prices for inputs and the agricultural commodity as it moves along the food value chain (FVC) across various places in the study areas (gendered trader survey). |

| Description of PhD-Topic | Analysis of Land use change and Climate variability impacts on the
hydrologic cycle in the Wami river basin This study is intended to make efficient use of now available extensive remote sensing data in assessing the relationship among the factors affecting the hydrologic cycle of the Wami River basin. In this case the time series of precipitation, temperature and remotely sensed land cover will be analysed against the remotely sensed evapotranspiration as a proxy of water balance changes in the basin. Then, the spatial-temporal patterns of remotely sensed evapotranspiration will be used to constrain a physically-based hydrological model, which in turn will be used to assess impacts of irrigation expansion and the introduction of infield rainwater harvesting agriculture (Trans-SEC upgrading strategies) under extreme climate condition scenarios on water availability in the Wami River basin. |

| Description of PhD-Topic | Applied Method: The focus of my PhD work will be on the interactions of rural household livelihoods, food security and welfare of smallholder farmers in Morogoro and Dodoma in rural Tanzania. Assessment of livelihoods' integration in small-scale agricultural value chains will be done. Aspects of rural finance, shocks, vulnerability to food insecurity and resilience will also be analyzed. Using primary household survey data, descriptive and econometric approaches will be used in the analysis. Expected result: Better understanding of relevant forms of livelihoods integration to small-scale agricultural value chains, levels and extent of shocks and vulnerability to food insecurity and resilience of rural livelihoods. |

| Description of PhD-Topic | In Tanzania, small-scale farmers largely depend on natural resources for income and consumption. The natural resources utilized are either based on own properties (land, agroforestry, soil etc.) or public resources such as forests, community land, rivers, lakes. The focus of this PhD-thesis is to analyze the importance of natural resources such as non-timber forest products for small-scale farmers. Thereby, a closer look will be taken at the role of natural resources for food security (directly and indirectly), their regional and temporal differences in utilization, sustainability of utilization and their role as a safety net in the case of shocks occurring. The research will be based on primary household survey data. Methods applied are based on econometric and spatial models. |

The approach involves application of geostatistics, artificial intelligence and remote sensing methods. Expected result: Improved predictive capacity and utility of crop simulation models, through better scaling of soil hydraulic properties from plot, region to higher levels to provide spatially-explicit decision support in food crop production management at various scales. |

| Description of PhD-Topic | The PhD study aims to test the suitability of sorghum, pearl
millet, sunflower, upland rice and maize in the research regions,
Dodoma and Morogoro. A focus is to analyze the effect of two management
practices, time based weeding and tied ridges on the soil water status
and the performance of the crops. Four consecutive trials are conducted at ARI Makutupora, Dodoma. In the dry season climatic scenarios are mimicked through drip irrigation and combined with drought events. In the rainy season rainfed conditions, life saving irrigation and full irrigation treatments are combined with weeding strategies and tied ridging. This study is expected to facilitate a climate sensitive selection of crops in regions where unpredicted rainfall occurs, to explore the suitability of alternative crops and to validate current crop water models. Furthermore, the outcome is expected to facilitate an efficient planning of irrigation water, its amount and timing of application, used in addition to rainfall. |
