  • Impacts of climate change on rice production in Africa and causes of simulated yield changes

    • Authors: Zwart, S.J.; Oort, P.A.J.V;  Advisor: -;  Participants: - (2018)

  • This study is the first of its kind to quantify possible effects of climate change onrice production in Africa. We simulated impacts on rice in irrigated systems (dry sea-son and wet season) and rainfed systems (upland and lowland). We simulated theuse of rice varieties with a higher temperature sum as adaptation option. We simu-lated rice yields for 4 RCP climate change scenarios and identified causes of yielddeclines.

  • Impacts of climate change on cropping patterns in a tropical, sub-humid watershed

    • Authors: Zwart, S.J.; Duku, C.;  Advisor: -;  Participants: - (2018)

  • In this study, we analyse the impact of climate change on the potential for increasing rainfed cropping intensity through sequential cropping and irrigation expansion in central Benin.The results also show that the irrigation potential of the watershed will be at least halved by mid-century in all scenario combinations. Given the urgent need to increase crop production to meet the demands of a growing population in SSA, our study outlines challenges and the need for planned development that need to be overcome to improve food security in the coming decades.

  • A Planning Support Tool for Scenario Analysis of Low Carbon Transport Plans in a Data-Poor Context

    • Authors: Shrestha, R.;  Advisor: -;  Participants: Zuidgeest, M.; Flacke, J. (2018)

  • Climate change is a global issue that needs to be addressed by both developed and developing countries. Nevertheless, it is being ignored in many developing countries because of their urgent need to give preference to development activities (Halsnæs and Verhagen, 2007). In addressing this dilemma, the notion of low-carbon development (LCD) has emerged from the discourse on climate change (Tilburg et al., 2011). Definitions of LCD commonly mention reducing CO2 emis-sions, intensive use of low-carbon energy sources and ensuring economic growth by reconciling national mitigation priorities with national development needs (Tilburg et al., 2011; Yuan et al., 2011). One key mitigation strategy is to lower their carbon footprint in cities and make them more sustainable.

  • Natural freeze-thaw cycles may increase the risk associated with Salmonella contamination in surface and groundwater environments

    • Authors: Rocard, J.M.;  Advisor: -;  Participants: Asadishad, B.; Samonte, P.R.V.; Ghoshal, S.; Tufenkji, N. (2018)

  • We investigated the influence of temperature fluctuations around the freezing point, known as freeze-thaw (FT), on the inactivation rates, growth, and biofilm formation of a manure-isolated strain of Salmonella typhimurium. Moreover, the effects of FT on the transport characteristics of S. typhimurium in quartz sand were monitored in model porewater solutions of two different ionic strengths (IS: 10 and 100 mM KCl) and two different humic acid (HA) concentrations (1 and 5 mg/L). Increasing numbers of FT cycles were found to decrease the deposition of S. typhimurium onto quartz sand and increase the percentage of detached cells in sand-packed column experiments. Based on the calculated bacterial attachment efficiencies, the predicted minimum setback distances between the location of ...
