How to estimate the Ecological Value of a small irrigation reservoir?

Published on by in Academic

What is the best way to quickly estimate the ecological value of a small irrigation tank (reservoir) without field studies? Are there some existing thumb rules that can be used? I am investigating the effect of negative water quality to aquatic life and downstream water pollution control. I am looking for your expert inputs on the topic.

  1. in my opinion a pond size 200x200x3feet deep located at the lower level of the farm into which all the rainwater is directed & lined at the bottom with LDPE PLASTIC SHEET with bushes around it to reduce wind evaporation can irrigate a 2-3 acre farm during the dry season for quick growing crops which require less water

    You may find the cost of water supply via conventional and currently avaiable methods being used in the same area and simply compare it your proposed solution. Othervise ecological values may not be accountable

  3. You can use a number of extra-market valuation methods such as contingent valuation or travel cost methods.

  4. To understand ecosystem services it is useful to evaluate the types of benefits provided by lakes, ponds, and reservoirs. A non-exhaustive list of benefits is presented and more information is available, you may like to consider this website for your study http://epa.gov/aed/lakesecoservices/ecosl.html

Le réservoir est il ouvert? l'odeur ? le liquide au travers du récipient est il clair ou trouble? Y a t il de la vie ? Y a t il des matières en suspension? La recherche principale: l'eau est elle Biologique?

    Hi Goden !

    There remains many shortcomings if we do not collect the actual field data to understand multiple parameters that will draw the complete picture of the problem & then the solution.  But, you can please refer to the following links that may help you work out your task, without going to field. 1. http://www.academicjournals.org/article/article1379673348_Mustafa%20and%20Noori.pdf 2. http://publications.iwmi.org/pdf/H044105.pdf 3. http://www.isprs.org/proceedings/XXXVI/part7/PDF/067.pdf 4. http://www.ccsenet.org/journal/index.php/jsd/article/viewFile/7338/5716 5. http://iri.columbia.edu/~ines/My_IRI_ProjectsO/Gujarat/ines-dvd/Eudora/attach/PhD_Alexandridis_en.pdf 6. http://www.nih.ernet.in/abstracts.html   Many more related to GIS and Remote Sensing you may find by googling......   Do well !

  8. Dear Goden, Addressing your point seriously requires a bit more information. The ecological value of a reservoir (water conservation strategy) is linked to many parameters: size of reservoir, cost of reservoir, material used to build it, type of water pipes, needed land space, cost of land, expected water quality, type of irrigation, type of soil, type of crop, water demand in quantity, price of water, evaporation ratio, price of electricity per kWh, etc... Ready to help whehn you are ready, Good luck, Laurent

  9. Methods about natural resources valuation.

    In this website you will find some interesting information about natural resources and valuation.

    http://www.teebweb.org/

    Also some manuals and several important articles here. If you look carefully in publications I guess you will find what you need. I use to volunteer on translation and know that many people around the world do the same. There are so extensive material on short video classes available on youtube.

  11. Mabaya, Greetings from Phildelphia! Right there is Japan, where , ESPECIALLY IN EQUATIC PROTOCOLS and GREEN HOUSES, THE WATER IRRIGATION IS COMPUTER CONTROLLED; tO the Fish nurseries and to THE BASE OF EVERY PLANT; The water with its neutriants is very careully channeled in from resevoirs. My technology has been used very successfully in Japan both for Aquatic Nurseries, in Aquariums and Agricultural purposes............................even to the point of utilizing Domestic Urine rich water for agriculture use. If it intertests you, I can give you the pointers and the people in Japan to contact. If it is your pleasure, you may even write to me at: etsi412@aol.com. Regards, Justin
