  • Assessment of recent temperature trends in Mangla watershed

    • Authors: Yaseen, Muhammad;  Advisor: -;  Participants: - (2014)

  • Climate change in the region in terms of changes in temperatures may seriously affect snow melting rates in the watershed and hence flows at dam. The main source of flows is snowmelt and rainfall that varies with temporal and spatial scale. So, understanding of spatial and temporal variability of climatic parameters is most important for the management of water resources. The present study was conducted to test the existence of monotonic trends and relative change (step change) in the annual and seasonal regional maximum, minimum, and mean and diurnal temperature data produced by thiessen polygon method from a meteorological network of stations in Mangla watershed for the period 1971-2010. Significant trends were detected by applying the student t test, Mann Whitney U, Spearman and ...

  • Sixty percent of small coffee farms have suitable socio-economic and environmental locations in Rwanda

    • Authors: Mukashema, Adrie;  Advisor: -;  Participants: - (2016)

  • Evaluating crop suitability is usually based on traditional land approaches in many countries, using only agro-ecological zoning and soil data. However, land use is also controlled by socio-economic and other biophysical factors. It is actually unknown how coffee suitability is influenced by such socio-economic and biophysical factors. Therefore, here, we studied all known factors that influence coffee production in Rwanda using an inventory of small holder coffee fields, including at least 200 coffee trees. We identified 29 potential factors, including demography, and environmental factors such as climate, soil and topography. These factors were reduced to 17 variables explaining 86 % of the total dataset variability, by factor analysis. The dataset was subsequently stratified into...

  • What do New Yorkers Think about Impacts and Adaptation to Heat Waves? An Evaluation Tool to Incorporate Perception of Low-Income Groups into Heat Wave Adaptation Scenarios in New York City

    • Authors: Matmir, S.;  Advisor: -;  Participants: - (2017)

  • Low-income residents are among the most vulnerable groups to climate change in urban areas, particularly regarding heat stress. However, their perceptions about heat and the impacts they face go often undocumented, and are seldom considered in decision-making processes delivering adaptation. This paper presents a robust tool to allow the integration of perception, concerns and impacts of different income groups in urban adaptation planning and governance, using the City of New York as a case study. Employing online interviews—a solid method to reach poorer households—and Fuzzy Cognitive Mapping, we compare impacts and adaptation perception to heat and simulate adaptation scenarios. Results reveal that lower income groups are more concerned about impacts of heat waves than middle- an...

  • 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 agricultural water resources and adaptation on the North China Plain

    • Authors: Hu, S.; Mo, X.;  Advisor: -;  Participants: - (2017)

  • Climate change is having a considerable impact on the availability of water resources for agricultural production on the North China Plain (NCP). Global climate model (GCM) ensemble projections predict that by the 2050s, the increased crop water demand and intensified ET resulting from global warming will reduce water resources surplus (Precipitation–ET) about 4%–24% and increase significantly the irrigation water demand in crop growth periods. This study assesses possible mitigation and adaptation measures for enabling agricultural sustainability. It is revealed that reducing the sowing area of winter wheat (3.0%–15.9%) in water-limited basins, together with improvement in crop water-use efficiency would effectively mitigate water shortages and intensify the resilience of agricultu...

  • 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.
