  1. 1. Future yield performance of ZS265 and ZS263 maize varieties and information dissemination for adaptation to climate change : a case of the Zimbabwean maize cropping system

    University essay from SLU/Dept. of People and Society

    Author : Vimbai Ruvengo; [2017]
    Keywords : APSIM; extension worker; drought tolerant; socio-ecological; AGRITEX; resilience;

    Abstract : In an effort to design a sustainable maize cropping system in Zimbabwe, attain food security and build resilience against climate change, achievements in crop breeding are evident by the introduction of Drought Tolerant (DT) maize varieties. The study aims to analyze the impact of climate change on DT maize varieties that are characterized to be drought tolerant and yield productive under future climate conditions. READ MORE

  3. 2. Effects of simulated rainfall intensity on water flow through soil in two tillage systems

    University essay from SLU/Dept. of Soil and Environment

    Author : Maria Sandin; [2012]
    Keywords : heavy clay soils; reduced tillage; macropore flow; rainfall simulator; dual-permeability model;

    Abstract : Diffuse losses of phosphorus from agricultural land to freshwater reservoirs have gained increasing interest in later years. Resent research suggests that phosphorus is mainly transported from the fields through macropores, and that soil under reduced forms of tillage can develop a higher macroporosity and thus an increased risk of phosphorus leaching compared to conventionally tilled soil, because of the more rapid flows of water through the soil.

  4. 3. Uppfångning och kvarhållning av 134Cs och 85Sr i olika växtutvecklingsstadier

    University essay from SLU/Dept. of Soil and Environment

    Author : Anna-Lisa Mårtensson; [2012]
    Keywords : cesium; kvarhållning; LAI; motåtgärder; strontium; radioaktivitet; raps; uppfångning; vall; vete; växtutvecklingsstadier;

    Abstract : Emissions of radionuclides to the atmosphere can lead to wet deposition on plants in the event of rainfall. An increased level of radioactivity in the plants may occur due to interception and retention of the radionuclides. If the content of the plants is above the threshold limit value, entire yields may have to be destroyed. READ MORE

  5. 4. Water infiltration in the Nyando River basin, Kenya

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Aida Bargues Tobella; [2009]
    Keywords : Lake Victoria basin; Nyando River basin; steady-state infiltrability; bulk density; erosion; gully; runoff; sediment generation rate; double-ring infiltrometer; rainfall simulator; trees; vegetation cover; agroforestry;

    Abstract : On-site and off-site effects of erosion in the Lake Victoria basin are some of the main contributors to the actual situation of poverty which is facing its population, one of the densest in the world. The Nyando River Basin (Western-Kenya) was identified as a regional erosion hotspot and one of the main sources of sediment and phosphorous into the Lake Victoria (ICRAF, 2001). READ MORE

  6. 5. Using cloud resolving model simulations of tropical deep convection to study turbulence in anvil cirrus

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Lina Broman Beijar; [2008]
    Keywords : cloud resolving model; tropical cirrus clouds; TRMM BLA experiment; anvil clouds;

    Abstract : Identifying the dynamical processes that are active in tropical cirrus clouds is important for understanding the role of cirrus in the tropical atmosphere. This study focuses on analyzing turbulent motions inside tropical anvil cirrus with the use of a Cloud Resolving Model. READ MORE
