    Although my comment is coming in this late, I would like to add my voice on the services that we get from ecosystems. Diverse in their nature, different ecosystems render us varying services too. From the fresh air we enjoy under a tree to the wild fruits that add nutritional value to our foods. From the clean water we enjoy from the deep wells to the beautiful flowers and animals that add value to tourism. My specified piece of land as described in the assignment one provides all these except tourism services.

      ‘Free Culture’ and/or ‘Subsidy Culture’ have been dominating different world nations purely on political considerations by which people who are habituated to these cultures remain forever dependent on external support and lose the spirit of self supportive culture. This trend eventually serve to divide people all over the world in as much as the fact that ‘Giver’ is always rated as superior to ‘Taker’, Therefore, nothing should be provided ‘Free’ to any body. There is a Chinese proverb ‘ Do not serve a fish to any body but train him/her how to catch a fish.’ Thus, it is essential to inculcate the spirit of self reliance.
      Land degradation worldwide can never be stalled unless ‘Soil-Water-Air-Plant-Animal-Human Continuum’ is maintained through human effort and responsibility all over the world. There is a historic evidence to prove that any ‘Resource’ cited in the continuum if removed, would be catastrophic to global peace and prosperity due to which quality life of all organisms becomes a casualty.

    The forthcoming Live-event exposes us to crucial subject i.e., on economics of land degradation.
    Eagerly waiting to participate in event enthusiastically.

    It will be a really interesting event! As I see the ELD-MOOC Initiative has integrated some of the best professionals in their field!

    Jusqu’à présent je suis nouveau mais je commence à saisir combien de fois ces discussions sont très bénéfiques et ça permet d’avoir beaucoup d’analyses sur la gestion et la protection des ressources naturelles et aussi sur l’évaluation des coûts merci pour toutes ces personnes qui sont soucieuses du devenir du monde dans sa globalité

    Looking forward to the forthcoming live event. It will be my first one ever as I missed the previous ones due to poor connections. I hope this time around it works.

    Thanks for making the live events available via YouTube as for some reason I’ve been having technical challenges in logging in to participate in the live events or watch recording on original platform.

      I agree with you, dear Rianne, me too I have technical problems – I can’t install Java on my computer (I tried many times)…I really wish to attend the live events of this interesting Mooc!

    same here! just don’t seem to be able to get to the live events due to “technics snags”!! Glad it’s available on you tube.

    The live event would significantly break the ice to an wonderful start to pin point strong, sustainable and economically viable decisions to realize the benefits following the creation of balance sheet on ecosystem services provided in orderly and systematic way which have a positive influence on stake holders and people in general. I look forward for the event. Thanks.

    j’ai aussi la même préoccupation que vous toujours des problèmes techniques nous empêche de suivre les événements en direct

    Prof. Dr. Hans Hurni:

    You were telling that you are calibrating the model and then validating the same for larger catchments. Should you kindly let me know at what scale the calibration is being done and what scale the validation? Is SWAT the only model used for hydrological analysis?

    Thank you

      Prof. Hurni asked me to post his reply:
      Q: This project considering the extensive crops being implemented in Ethiopia due to the purchase or lease of land by foreign agribusiness companies?

      A: Component 1 (land use and cover analysis on pixel basis) will help us identifying large-scale land acquisitions including foreign direct investments, provided that these companies have started to grow crops. Many of the land claims did not start in fact, so it is very difficult to assess the areas where investments will be made. The Centre in which I am working is cooperating closely with the International Land Coalition, in fact it is developing the database system used for crowd sourcing at the global level. While in the database the information on Ethiopia is extensive, with many claims supposed, it is not yet sufficiently geo-referenced to allow for a concrete analysis in the ELD project. This can change any time, however, as soon as the land uses are visible on the ground.

      A: Our SWAT application relates to small catchments of 1-7 square km in size, for which we have storm-to-storm data for over 10 years. Calibration is done there according to our requirements for SWAT, e.g. by using a selection of storms, months or whole years, i.e. what we want the model to predict: single storms or periods from weeks, or months to years. Validation there is possible by applying the SWAT model to the remaining set of available data. However, we now also like to know if the calibrated SWAT model also works for larger catchments. In one case where we have a larger catchment (about 48 square km) in which our smaller catchment (1 square km) is embedded, we can do a validation by comparing the SWAT modelling for the larger catchment with the data set we are generating there. We have not done it yet, and I am of course eager to know how well this will work. Apart from SWAT we have tried Erosion3D, and also other, simpler models for which I would need to give you a contact.
