Water Threats & Challenges

Abstract

In a world 4 °C warmer it can be calculated that the atmosphere will contain 25% more water. Much of this water can however be kept there. But it will also precipitate more "violently" than in the current average temperature on some places.

Most dry areas of today will due to the increased heat be even dryer. The drought and difficulties for man, animals and plants to reach the necessary water to achieve homeostasis, growth and regeneration will thereby decrease considerably. In some regions - like the monsun regions of the world - even more heavy rains are expected causing considerably increased ersosion.

The tendency on average should therefore be that in most regions the soil ground water will sink due to increased evapotranspiration from plants and soils.

It is therefore anticipated that within traditional agriculture the crop yields will decrease considerably and perhaps with 80% already 2050 in the USA - today the biggest agricultural exporter in the world. This will definitely put new "agrochallenges" to global agriculture. Click "Water Solutions" button on the front page.

There is a big risk that when the glaciers of the Himalayas have been thawn down completely the rivers today reaching the sea will bee totally dried out for long periods and be fluded during short periods of monsun rain.

Even several rain forests seem to be suffering from drought during periods, where their non drought tolerant species may be dried out and cause wild fires setting enormous amounts of gasified biomass as CO2 into the atmosphere. When the drought period cease and follows by rain there will be no adapted plants to take up the nutrient capital from the rain forest. It will therefore be washed out quickly into rivers and out into the sea. This will considerably decrease the fertility of the former rain forest area and accelerate the process towards desertification on big areas which are currently healthy rain forest regions.

The global photosynthesis and efficient photosynthetic area will thereby decrease considerably.

Thousands of rainforest species will thereby be extinct.

The species diversity will decrease in a non repairable way.

This will cause an ecological shock in many areas that will never come back to its original point of today.

Traditional democracy will herby be put on extremely hard global tests.

Also currently very humid areas like UK seems to ultimately during the heat shock reach a very dry and warm climate today typical for North Africa according to Peter Cox, Hadley Met Center, UK.

Technically mankind must be prepared on a water struggle harder than ever in almost all parts of the world, with in most areas less water due eto increased heat and transpiration and in a few areas a heavier load on rivers that will more often be fluding big areas never been fluded before. 

To counterbalance this it will be necessary to desalinate sea water in big scale for primary human and all kinds of processing and societal aims including the needs for photosynthesis and C sequestration within Project AgroChallenge. The sea is currently covering 71% of the planet surface.

If we take this extra "starting civilizational cost" all people will have a better chance to live in prosperity. With this approach it is definitely no water deficiency on the planet. It will also generate very much of local employment in area where today very little activities is seen. The energy for this must be sun driven and will also produce electricity from biomass or other sun driven sources.

Project AgroChall will booster desalination projects globally in the vicinity of today dry semidesert or desert areas.

31% of all continantal land is currently classified as deserts. It means that 5,2 Gha are currently deserts. Project AgroChall regard about 1 Gha as a necessary area for C sequestration. Deserts are a best choice simply because there is essentially no photosynthesis at all in these areas, so we don´t cut any photosynthesis , just add more land to "the photosynthetic zones of the planet". After 150 years of fossil C burning it seems necessary - but just 20% of the desert dry areas of Africa,  Asia, Australia, Europe and USA. However we can only work commercially in regions where democracy and stable political conditions are estimated to be prevalent by scientific experts during the comming 50 years.

In EU - my "home range" - e g Portugal and Spain are ideal starting zones for advanced desalination for high yielding sequestering crops followed by long term C sequestering in a spontaniously dry climate in areas with today very low spontanious photosynthetical annual yields.

Australia is another example of a continent where there is lots of drylands and deserts and where all the infrastructure is present and also an ideal political stable situation for long term  sequestrations. This include logistic challenges solved professionally and in a most cost efficient way by Project AgroChallenge if You just click us.

Some further examples of photosynthetically free regions (PFR) due to severe water deficiency are seen below in sand colored areas compiled by NASA.

So if the first growth limiting factor for these areas are eliminated desert regions have a very high yield potential, because they always have a very high sun incidence during a very high percentage of the year. The temperature is also mostly favorable for high speed growth during long periods of the year. At the end of the growing season iirrigation is stopped and the crop get dry in a very short period of time before final C sequestration.

Within a little more than a year from Your first "payclick" You will see our "pyramids" growing proportional to the accumulated orders from people around the world - people who want to protect their own property and prosperity and also have a strategy for sustainabel survival for themselves and their ancestors and wish to conserve the current biodiversity of the planet.

- We expect You soon to be one of them !
