I...need....water.....ahhhh

Water is fast becoming the world’s most precious natural resource. You can read about droughts in various parts of the world and about human conflicts over access to water supplies, but until it hits close to home most Americans won’t recognize the value of a clean clear glass of pure H2O! Lately, filtering and boiling our drinking water each day has made us a bit more appreciative. My limited experiences with water’s importance began in Humboldt county California where farmers went head to head with fisherman, environmentalists and local tribes over the water use rights of the Klamath River. Farmers wanted more water for their crops, but the river was drying up and choking on algae and weeds and the salmon which for eons swam up the river to spawn were cut off and left for dead with roe still in their bellies. For at least one year, an entire generation of Klamath River salmon never spawned. That sucked. After that, there were the massive fires in southern California which were fueled by dried up and diseased forests and there were the years of water shortages in San Diego and even in Durham when I moved to the east coast! It seems that anywhere I go, the story is the same.
We are becoming aware that Tanzania is on the brink of water related calamity. The country is mostly dry savannah. The water that falls here comes in air-born moisture during the rainy season from the coast passing right over the savannah and rains when it meets the interior mountains of the eastern arc. This would simply run off over the hard packed, cracked and cemented dry soil back into the ocean if not for the rain forests on the lower mountain slopes which help to keep the water in the system throughout the dry season. As I’ve mentioned before, about 50% of Tanzania’s electricity is generated from this water and of course it’s also used for farming. The Ruaha is the largest river in our area and it supports all kinds of animals from elephants and hippos to crocodiles as it flows across the country, spreading into a huge wetland at the coast. Apparently, and we just learned this, the Ruaha DRIED up for the first time ever during the dry season in 1993! This caused the riverbed and feeding wetlands to dry out and harden and for many animals to die of thirst and poisoning from drinking the remaining contaminated pools of water. Electricity shortages, desertification and stories like the one above are becoming a huge problem for Tanzania because people have moved into the limited forested area and have been cutting trees for fuel and to clear areas for farms which also siphon off water from the river. When the trees are gone, the whole country will dry up and blow away. Of course it sounds like a story that we’ve all heard a million times! The rainforest is disappearing and humans are consuming at an unsustainable self destructive pace. Indeed. So why do I even bring it up if it’s so common and inevitable? One, because this is really a blog about the zombocalypse and who says this isn’t one more click of the pawl on the big gear? Two, to explain this next photo- which is not so clear! Aloyce and I snuck up on these folks cutting trees and harvesting wood from Magombera. Ruth is infuriated because it’s also destroying the small remaining habitat of so many threatened species including the Red Colobus she’s studying. There is some concern at high levels of the government for the future of Tanzania’s ecology and so wood harvesting has been outlawed and entire villages evacuated from critical forests, but individuals do what they must to feed and shelter their families. There lies the rub. We see people chopping wood just about every day.



OK, enough of that! It’s Mdudu time. Let’s be glad that there are enough trees left for this bug to hide. We never would have seen this sucker if it wasn’t for Aloyce pointing it out because its camouflage technique is THAT good it can fool two sharp eyed wazungus from the city. In fact, you might recognize this bug from the movie Master and Commander where it inspired one of my favorite fictional characters, Jack Aubrey, to sneak up on, surprise and engage superior forces in a climactic cinema (cinematic?) marine battle.

Water shortages, food shortages, over harvesting of natural resources, carbon pollutents, all these and more are a direct result of global over population. Humans should quit multiplying.

the key to reducing the enormous out of control population of the earth is to begin with the elimination of all who preach such a hilarious notion.

Sad to learn about the water crisis:(
We do need more attention and scientists on natural resource management and conservation biology!

As I understand it, limiting or reducing the worlds human population does not require any human to be killed. So people with different political or religious beliefs can live and let live. Nobody's freedom needs to be trampled and there doesn't need to be any laws limiting the number of children that a couple can have! All we need to do is provide a better education for all people. This is the long term solution to most of the worlds problems. We should apply the most weight to this lever. Who can argue with that?

Hey Jack, I saw this and thought of you. I don't know if your internet connection can handle video but it's pretty amazing.

I'm posting here because I don't have your email so to keep this on topic... framing the problem as overpopulation is missing the point. If we all move towards more sustainable lifestyles there enough resources to go around for billions more than billions that are already here. That said, the quantity of potable water seems like the biggest obstacle to achieving that.

MGA-
It's strange, but we're unable to connect to youtube in TZ. I think that the site must be blocked or something. No video for us.It's true that what matters is our consumption footprint and we must address this issue but, billions more people sounds....crowded. What is the point of jamming more humanity on this fragile planet anyway? What about other creatures, nature and wilderness, things we can't live without. Where would we go to be alone? Why not increase the quality of human life rather than the quantity? This will happen inevitably, organically through personal choice if people become more educated and aware.

Hmm... try this link it's not using the youtube version.

I don't think it's an either/or proposition. As the quantity increases it doesn't and hasn't meant that quality of life in general is necessarily going to decrease. And as you say, with education, lifestyles change and population growth rates adjust accordingly (more education seems to equal less babies). So thinking of overpopulation as the problem seems to miss the point for me when it's really about general sustainability. Really we're in agreement on the big picture, it's just semantics.

I still feel Earth is at maximum capacity right now. Its harder and harder each year to find places to visit and get the feeling of being in the wild. And I live on the West Coast! This how ever, doesn't mean I believe there should be restrictions on births, or "...elimination of all who preach such a hilarious notion."
I think Jack's right. As people become more educated they will become more aware. Populations wil hopefuly learn to live life styles less destructive and more re-structive (if thats a word) they might think twice about having that sixth kid, not buy that new car and fix their old one, so on and so on.
The world needs more of its Wild places back. Needs more wild creatures back. Its important to humanity that we'll always have areas to visit where we can go to appriciate the natural order of life.

Off topic but, have you had a chance to fish yet in TZ? What kinds of fish are in the fresh water rivers, streams and lakes?

please,more education wont help this overcoruded planet,loaded with
non productive people wasting the air and resources of people who contribute to the well being of all.as harsh as it may be or sound
maybe china with one child law has some thought behind it.unless all contributed to society multiple children is nice,but steets crowded with useless populations is become a bourden to us all.hey jack any pics of you?your bro mik,lol..

Hi Jack!
I just spent the last hour or so reading through your blog (and Ruth's too!). Fantastic!!!
Keep this up! The pictures are so awesome. What's the inside of the "house" look like? Can you remind me of your email (do you check your Duke one?). Say hi to Ruth and keep blogging your incredible experience!
Best,
Scott

Hi Jack - I am so happy to have a moment here to take this all in. I am in awe of what you all are doing and am very excited for you both. That crazy insect that looks like an alligator - I have to send that photo to my dad for more info (he is a wacky entomologist). Tell me, have you had any VB there?

Interesting discussion of overpopulation! I have been thinking about this issue because I study the evolution of longevity and reproductive rates in humans. It was our ultimate adaptation (because culture and technology came along with it) and, at the same time, resulted in the demise of so many other species. But, evolution has no foresight...

I read some papers that mathematically model future demographics...if we had about two kiddie per female AND consumed as much as people in Portugal do - that is, considerably less than in the US and still have a comfortable lifestyle - we would probably do pretty well. In fact, reduction in birth rates have a much more significant long-term effect than changes in longevity or mortality rates. Education and reduction in birth rates seem to go hand and hand. Unfortunately, it is often the lack of access to effective and safe birth control that is the problem rather than the lack of desire to have less kids.

Anyway, great posts!
