دوره چهارساله دکتری
در خصوص کمی سازی آثار آلودگی هوای شهرهای بزرگ بر تولید منطقه ای و امنیت غذایی -در مرکز محیط زیست دانشگاه لنکستر
دوستان توجه داشته باشید پروژه سالیانه ۱۴۰۰۰ پوند به دانشجو کمک میکند و از این نظر تفاوتی بین دانشجوهااز ملیت های مختلف نیست ولی تنها شهریه در حد دانشجوی اروپایی/انگیسی را پوشش میدهد یعنی اگر دانشجو بین المللی باشد بخش بزرگی - در حدود ۱۰۰۰۰ پوند- توسط دانشجو پرداخت میشود.
دوره ولی از نظر مالی قوی است و احتمال منابع دیگر درآمد از جمله تدریس کم نیست.
Quantifying the impact of mega city air pollution on regional crop production and food security
The 2017 UN Food and Agriculture report highlights the risks to global food security as population and urbanisation rise. While the impacts of increasing CO2, temperature and incidence of drought on crop production have received considerable attention, the impacts of deteriorating air quality, which accompany urbanisation and industrialisation, have not. Surface ozone and nitrogen oxides (NOx) are directly toxic to plants, while particulate pollution reduces the levels of sunlight reaching crops. Exposure to these pollutants reduces crop yield and quality. Our recent statistical analysis showed that surface ozone across the USA cost 10% or 33 million tonnes of the country’s largest crop, maize. If such losses occur in a developed economy with strong emission controls, what impacts may be expected as pollutant levels rise in developing economies, many of which are also the most vulnerable areas of the globe in terms of food supply?
The interactions between the atmosphere and vegetation are complex and fascinating, but remain poorly understood. This project aims to provide this understanding, critical for developing appropriate regional policies, in 3 important agricultural areas in rapidly developing countries.
You will conduct an extensive analysis of crop yields, weather records and air quality monitoring data to determine how air pollution affects crop production under different climate and soil conditions. You will develop relationships to incorporate these effects in a specialised computer model of crop growth and development. You will apply this model to simulate the effects of air pollutants on crops growing downwind of 3 mega-cities (Beijing, Delhi and Lagos) and estimate how poor air quality in these cities reduces regional harvests of major crops both now and under future potential conditions. For the first time, you will be able to investigate how different air pollutants may combine to exacerbate the effects of each and to highlight the most vulnerable regions. The model you develop will be a cutting-edge tool that will enable you to explore possible mitigation strategies and aid policy interventions.
Lancaster University is a UK top 10 University with a worldwide network of individual and institutional partners. Lancaster Environment Centre is one of the largest centres of environmental research and teaching in Europe, bringing together leading environmental and social scientists to offer solutions-based research focusing on the world’s major environmental challenges. We are currently ranked 3rd in the UK for the real-world impact of our research. You will join dynamic research groups at Lancaster Environment Centre that are widely recognised as world-leading in the measurement and modelling of air quality,
climate and pollution, and understanding plant-environment interactions. Our plant and crop scientists have been at the forefront of the development of real-world solutions to Agri-food challenges. We have well-established relationships with leading international research institutions and you will have excellent opportunities to interact with world-leading researchers.
