Event Details
<strong>Centre for the Study of Regional Development, JNU</strong> a lecture by <strong>Dr Irene Marzolff</strong> Institute of Physical Geography, Goethe University Frankfurt am Main, Germany on <strong>Remote sensing with unmanned aerial vehicles (UAVs) for monitoring land-degradation processes in semi-arid landscapes</strong> Date: <strong>27th February 2015</strong> <strong>Abstract:</strong> 'Remote sensing with unmanned aerial vehicles (UAVs) for monitoring land-degradation processes in semi-arid landscapes' With flying heights well below conventional airplanes and centimeter resolutions, small-format aerial photography (SFAP) taken from unmanned aerial vehicles (UAVs) bridges the gap between ground observations and satellite imagery. For documenting and monitoring land-degradation processes, geomorphological forms and landscape patterns at various spatial and temporal scales, SFAP offers possibilities not given with conventional air photos or satellite images. From a methodological point of view, the small-format digital images may be analysed using a wide variety of remote sensing, photogrammetry and GIS techniques, ranging from visual image interpretation to multispectral classification to 3D analysis and DEM extraction. This paper will give an overview of the techniques and methods, presenting examples from 20 years of gully-erosion research and other land-degradation studies in semi-arid Spain and Morocco. <strong>About the Speaker :</strong> Dr. Irene Marzolff is faculty at the Institute of Physical Geography, Goethe University Frankfurt am Main, Germany. Dr. Marzolff has done extensive research in large-scale remote sensing with unmanned aerial vehicles (UAVs), small format aerial photography (SFAP), small format photogrammetry and GIS for high-resolution monitoring. Her areas of research interest are geomorphological processes, soil erosion, land degradation; effects of land use change and vegetation change on land degradation. Her publications include Small-Format Aerial Photography: Principles, Techniques and Geoscience Applications (Springer, 2010).

A warm welcome to the modified and updated website of the Centre for East Asian Studies. The East Asian region has been at the forefront of several path-breaking changes since 1970s beginning with the redefining the development architecture with its State-led development model besides emerging as a major region in the global politics and a key hub of the sophisticated technologies. The Centre is one of the thirteen Centres of the School of International Studies, Jawaharlal Nehru University, New Delhi that provides a holistic understanding of the region.

Initially, established as a Centre for Chinese and Japanese Studies, it subsequently grew to include Korean Studies as well. At present there are eight faculty members in the Centre. Several distinguished faculty who have now retired include the late Prof. Gargi Dutt, Prof. P.A.N. Murthy, Prof. G.P. Deshpande, Dr. Nranarayan Das, Prof. R.R. Krishnan and Prof. K.V. Kesavan. Besides, Dr. Madhu Bhalla served at the Centre in Chinese Studies Programme during 1994-2006. In addition, Ms. Kamlesh Jain and Dr. M. M. Kunju served the Centre as the Documentation Officers in Chinese and Japanese Studies respectively.

The academic curriculum covers both modern and contemporary facets of East Asia as each scholar specializes in an area of his/her interest in the region. The integrated course involves two semesters of classes at the M. Phil programme and a dissertation for the M. Phil and a thesis for Ph. D programme respectively. The central objective is to impart an interdisciplinary knowledge and understanding of history, foreign policy, government and politics, society and culture and political economy of the respective areas. Students can explore new and emerging themes such as East Asian regionalism, the evolving East Asian Community, the rise of China, resurgence of Japan and the prospects for reunification of the Korean peninsula. Additionally, the Centre lays great emphasis on the building of language skills. The background of scholars includes mostly from the social science disciplines; History, Political Science, Economics, Sociology, International Relations and language.

Several students of the centre have been recipients of prestigious research fellowships awarded by Japan Foundation, Mombusho (Ministry of Education, Government of Japan), Saburo Okita Memorial Fellowship, Nippon Foundation, Korea Foundation, Nehru Memorial Fellowship, and Fellowship from the Chinese and Taiwanese Governments. Besides, students from Japan receive fellowship from the Indian Council of Cultural Relations.
