In the 1970’s I investigated how erosion, runoff or soils differed according to land use and climate. I also became involved with the problem of relating this work the possible impaact of climate change in Europe as part of a Dutch Research Programme aimed at establishing the Bioclimatological Impact of Climate Change. However, after reviewing the then available information, I became convinced that there was an important need for data and information on both the relationships of ecosystems to climate and on there response to climate change. I became interested in studying relationships with climate from the perspective of dynamic systems and hierarchy theory research paradigm as an alternative to a statistically based approach. Withthin the major Issues of Climate Change and Land Degradation (fire, grazing and climate impacts on functioning of ecosystems) I investigated the following key research questions: 1) How are specific key ecosystem processes regulating hillslope hydrology and erosion affected by environmental change (land use, fire, drought etc.) 2) How are these processes related at different hierarchical levels and how can these relationshipd be applied to upscaling. 3) How can the findings from this research be integrated with socio-economic research to study human impact. I tried to answer these questions by: a) Initiating transect studies along climatological gradients in Colombia and. the Mediterranean. UNEP and the EU provided generous funding in two EU projects (ERMES I and II) that I developed and co-ordinated in collaboration with colleagues in Israel, Italy Greece, Spain, Germany and England. The second phase of ERMES was an integrated project in which socio-economic and physical drivers were considered together. b) Undertaking work in the context of Medalus (Mediterranean Desertification and Land Use) of which I was one of the founders. As one of the co-ordinators and steering committee of this very large EU project I have tried to develop a methodology for identifying environmentally sensitive land units at different scales areas in target areas. c) By setting up through grants from the Netherlands Research Organisation, a state-of-the art field site in Spain where hierarchical istudies of processes under different land use types are being made. d) By incorporating and introducing the methodology developed under c and my overall objective into international research programmes (GCTE and COST ACTION on soil erosion) e) By encouraging international collaboration on the Impact of Environmental Change on 2 Geomorphological Processes in the IGU Commission with this name of which I am the Chairman. Research on Environmental Change and Desertification Most of my current research is taking part in integrated land degradation and climate-change impacts studies in Southern Europe. Research themes include: a) developing a methodology for characterising the sensitivity of soils and landscapes to degradation. This is focused on developing indicators of ecosystem health from physical information (soil infiltration rates, soil crust development and aggregation, soil erodibility from soil physical and chemical properties) and on developing a response unit methodology. b) understanding the influencing of soil material properties on rill and gully erosion. This work has led to the development of a new model of rill development which is currently being elaborated in South Limburg and by means of laboratory experiments. c) Investigating linkages between processes, operating at different rates. affecting the degradation of Mediterranean landscapes. d) Investigations of the resilience and stability of degraded systems along climatological transects in Crete, Spain and the Judean Desert) Research in European Programmes Much of my recent research has contributed to EU research programmes (mainly EPOCH, ENVIRONMENT AND CLIMATE AND ENVIRONMENT). One of the main research projects has the name “Mediterranean Desertification and Land Use” (acronym Medalus), which was maintained under all of the above programmes) and which had between about 11 and 40 partners. In MEDALUS 1, I was responsible for co-ordinating a programme of field experiments set up at 7 locations across Southern Europe, for support work to other teams and for the data base and CD-ROM. The research included developing the concept of Desertification Response Units. Within the project “European Field Experiment in Desertification Threatened Area” (acronym EFEDA ) I investigated how dynamic soil and vegetation properties influenced the redistribution of water and how water redistribution is affected by land use change. This work was applied to develop a model of the effects of land use change on groundwater recharge. Currently I am co-ordinator of “ MEDALUS Project 1 The Core Programme ” This groups the major field and modelling research studies of Medalus that provide scientific underpinning of the other three MEDALUS projects (Target Areas, Regional Indicators and Ephemeral Channels). 3 Within MEDALUS, I am responsible for the international collaboration (with Toronto, New Mexico and Bar Ilan Universities), for a study on the effects of drought on soil erosion-plantwater relations in the Rambla Honda, Almeria, for research on indicators for identifying environmentally sensitive areas in the Guadalentin catchment SE Spain, for a study on the impact of grazing on soil -plant water relations in Lesbos and for the identification of the underlying geomorphological and pedological factors related to the distribution of environmentally sensitive areas in the Alentejo target area. Issues of Sustainable Land Use, Climate Change Land degradation and Development I have gained first-hand experience with these issues in developing countries mainly in Morocco, Lesotho, Honduras and Indonesia where I have undertaken research during short periods during the last twenty years. My interest in sustainability led to my becoming a cofounder of a Foundation with this as its goal more than ten years ago. Working through the International Eco-technology Research Centre in Cranfield, I am interested in contributing, from the biophysical side, to hierarchical models that link social and economic drivers of land degradation to biophysical ones. As Chairman of the IGU Commission on Geomorphology and Environmental Change I am concerned with developing research initiatives on the interrelationships between geomorphology, climate change and land use change. My interests in climate impact studies began more than ten years ago when I organised workshops on the Bio-climatic Impact of Climate Change in the Mediterranean region.. TEACHING As head of the geomorphology section, of the Department of Physical Geography and Soil Science, I have been responsible for the overall teaching of geomorphology and for the degree specialisation in Process Geomorphology. I currently teach first and second year courses in process geomorphology and hydrology. In the third and fourth year I give an optional soil erosion course, supervise MSc. level individual research projects, hold capita selecta lectures in process geomorphology and soil erosion and am responsible for a field monitoring course. I am currently supervising 5 Ph.D students and usually have between 1 and 2 post doc visitors. The course in process geomorphology gives a theoretical and methodological introduction; deals with fluvial processes in river channels; hillslope processes; soil erosion and geomorphology and environmental change. The hydrology course consists of a theoretical component in which basic hydrological concepts are taught; a practical component in which students are instructed in the analyses of hydrological data and in methods of measurement and a series of case studies to demonstrate application and relevance. The fourth year course on soil erosion (6 to 9 months) covers the factors and processes of soil erosion in the context of soil erosion assessment and control. This is followed by a practical course in which students undertake a 6 week period of field and laboratory work that forms the basis of a written report. The "individual research" course is aimed at instructing students in the formulation, execution 4 and reporting of scientific research. On average three students per year are assigned research problems in the field of process geomorphology and land degradation. and these receive intensive tuition during tutorials, fieldwork and in laboratory research. The research is undertaken within the framework of international research projects so that the students gain experience working in teams and in integrated projects. The students employ combinations of field and laboratory measurements or experiments, modelling, GIS and air-photo interpretations according to the specific requirements. In addition short modules on desertification and land degradation in the tropics are taught as components of courses on environmental topics to students from other departments. Lectures are also given each year on soil erosion within the International Courses at other universities. I have been an external examiner for the MSc Land and Water Resources programme of Cranfield University (Silsoe). On average I am an external PhD examiner two or three time each year. ADMINISTRATION At present I am a member of the departmental Research Committee. On several occasions I have been a member of the Departmental Advisory Board (Raad; 10 years), The Departmental Committee (Bestuur; 6 years; 2 years Vice-Dean :and for 6 months Chairman. I have also been a member of the Teaching Committee and of the University Council. I am Chairman of the International Geographical Union (IGU) Commission on Geomorphology and Environmental Change, organising at least two international meetings and producing three newsletters each year with 400 corresponding members. I have been and am a co-ordinator of several research programmes. Currently these include EU Project on Desertification and a research programme on the hierarchy of geomorphology processes funded by the Dutch Science Research Council (N.W.O). As head of the geomorphology section, I am responsible for writing and developing and implementing the geomorphology research plan as well as the departments contribution in geomorphology to the Inter-University Research School to which my department belongs.
