Water conservation in 20th century europe and california websites?

I'm doing a research paper, and I need some websites or information if you have any?


the prompt is: explain how the Europeans improved and conserved water in the 20th century. Explain the similarities and differences between the methods Europeans used to improve and conserve water and the methods used to improve and conserve in California today. Draw conclusions about how water consumers might be affected if 20th century European water usage was applied to the use of water in modern day California.





I found some articles already in Thomson Gale and Ebsco, but I can not look for other articles in those websites in my home, only in school. If you have any useful websites please tell me.

Water conservation in 20th century europe and california websites?
where in Europe ? and when ?


the Moors where into water harvesting in the past ,much more than modern society is today although remnants of this concept remain with the Spanish and Portugeese ,





modern Europe was much less sophisticated than ancient Europe and North Africa ,





the only concept alive in California is the water harvesting of Permaculture ,





here is a general consensus about WATER its distribution ,harvesting ,eficient use ,and draw you own conclusions





Why should we all be responsible for saving water?





because there is so little that we can use





------------------------------...


25% of the planets surface is land


75%of the surface is water and it is rising





------------------------------...





97%of the Earths water is salt





fresh water is only 3% of all the Earths water


most of it is beyond out reach





now much ice is melting and running into the seas fresh water lost for ever.





STORAGE or Location of % of the fresh water


ice and glaziers 74%


groundwater 800 meters + 13.5 %


groundwater less than 800meters 11.o%


Lakes 0.3%


soils 0.006%


Atmospheric in circulation 0.0035%


rivers 0.03%








frozen land or permafrost is not included and represent an unavailable storage of 40%





so of the 3% about 11.6 ,is easily available to us ,in rivers, lakes and ground water surface aquifers,more and more of this is becoming contaminated





EFFICIENT WATER USE





IN THE HOUSE


one can connect the sink straight to the toilet sistern and so use the water twice ,first to have a shave and then to flush the toilet


also if you bend the ball valve you can regulate the level of the sistern





and always have your grey water and black water seperate


so that the sink and shower water goes directly into the garden saving on irregation and at the same time ,making the sewage smaller and easier to deal with ,this also goes and iregates the garden but via a sitern of two compartments and a french drain ,on which you plant trees,





ON THE LAND


economic systems of irregation like drip irregation


and design using a lot of stone walls ,that condense water in the night


and planting leafy plants for the same purpose


building wind breaks ,to counter act the drying effects of the wind and farm towards agro forestal ,using as many trees as posible to limit evaporation .using shade nets before we have tree cover





and use MULCH





by cutting down the weeds before they produce seeds and leave them where they fall,they will cover the ground and put even more organic matter on top,you can use saw dust,leaves green or dry,and when you plant make a little space and plant in the mulch.this is the easiest quickest and by far most benificial way(for the quality of you soil)to prepare the land for planting





to prevent weeds from coming all you have to do it turn out the lights,you can even use cardboard or black plastic(this is good for strawberries because they will rot if they touch humid ground,and the bugs can get to them).





mulch is the same principal as compost but it includes the whole garden surface


the top part of the soil where the topsoil is being produced houses a world or microbiotic life.





Mulch is organic material green or dry that covers the ground,the thicker the better the composting process will turn it in to black topsoil





the humidity is preserved underneath and promotes the devellopment of worms(their exists no better compost than their excrements)and a variety of micro biotic life which together with the mulch produce more topsoil.





the mulch also keeps the ground temperature even and guards against the impact of the rain ,which would other wise brings salt to the surfave if on unprotected land





Mulch also prevents the soil from drying out because of the sun and,








WATERHARVESTING





the natural way of nature is to evaporate moisture for clouds and this gets blown to places with less water any way ,what obstruct the clouds from getting to deserts ,tend to be mountains that are in the way,


but generally speaking ,the normal weather patterns spread rain evenly over the planet to balance out the temperatures and humidity.





As far as catching rain is concerned ,we do this all the time ,and have done so already since Babylonian times,and is a part of the more advanced Agriculture,that existed with the Egyptians,Central ,and south American indigenous peoples,and many others ,today we call this water harvesting.





In Permaculture the rule is to harvest water to the point of Zero runoff.


this means that all of the rain that falls on an area is absorbed by the terrain and not a drop leaves it.





by building dams,ponds or swales, with interconecting ditches,


if there are enough of these ;the places ,where before the rain water ran over the ground into the rivers and on to the sea ,(in a matter of hours or days),It now runs into absorbant dams or swales and saturates the ground and eventually reaches subteranean water deposits ,taking many months to do so.


Or it fills up ponds that can be used for Aquaculture.


And so a convex situation that repels water is transformed in a concave ,absorbant one and turning the area in to a sponge.





in Spain and Portugal ,which still display many examples of the conquering Moorish influence,One can find many remnants of Waterharvesting,such as aquaducts and tanks underneath the patios ,which collect the rain water from the roofs ,to be used in dryer times.





in Arabia ,on a large scale ,land has been shaped to catch and lead,rain water into sandy areas or to agricultural lands.sand is almost as good as dams because it absorbs water and holds it.
