Zaï Soil Rehabilitation

As featured in the 2010 documentary The Man Who Stopped the Desert, Zaï pits (called Tassa in Niger) are a simple, but effective drylands soil rehabilitation strategy.

A practice indigenous to the arid Sahel strip, they were reintroduced and brought to prominence again in the 1980s by Yacouba Sawadogo, an activist and expert farmer from Burkina Faso. He modified the traditional design into the multi-functional model used today.

Zaï pits deal with the related problems of aridity, erosion, and soil compaction, particularly on difficult-to-cultivate sloped land: crusted land exhibiting these features is locally called “Zippelle.”

During the dry season, pits are dug 15-20cm deep, and 20-50cm wide, and earth from the pits is arranged in a semicircular formation on the lower grade of the slope, to increase water retention. Organic matter such as raw compost, plant matter, or manure is added to the pits, creating a depressed, moist, water-retentive, nutrient-rich cavity in which trees or crops can be planted.

The raw compost in turn attracts termites, who burrow in the surrounding soil, loosening it to increase water and root penetration, and also digesting the raw organic matter in order to make the nutrients bioavailable to the plants.

The World Bank reports that if done properly, this technique increase yields by 500%. [1] Combined with agroforestry strategies, like the planting of leguminous trees (traditionally, Acacia: see the “Great Green Wall”), it has the potential to reverse further soil erosion, compaction, desertification along the border of the Sahara.

Commissions- Updated

trails-of-tears:

Hi! My name is Erica “Bro” y Media or Doddle and I know have another post going around with my commissions but I am reposting since it is slowing down and i’m redo my pricing and just everything about it in general. I am also opening up my nude commissions too. Some back story about this, I am trying to move out of a abusive home life and I am trying to stay out of FSSW too because it been demetimed to my mental health and I get sick often – partly due to the stress of being the peacekeeper, my school and medical debt and my house is not the best living contiondtion. I am a really disabled mentally, physically and neuoguailly mix race latin and southeast native american and it is really hard for me to keep and hold down regular jobs along with the fact a lot of people will not hire me due to reasons listed before and where I live at not many people want to hire from due to the reapation it has, along with the fact several of my past abusers and school bullies who assaulted me work or visit these places too. Also it been really hard to save money because I have to buy my own goeriecies/food, help my parents out or get my money stolen, and I have to keep up with my own bills since my parents are also struggling and I am the only one out of my siblings who actually working some at the moment. I Have a lot of debt from quitting school and I owe the school over a thousand (1,000+) for quitting and them starting the legal process to get their money back – even though I do not have any money. I also owe the hospital over two-thousand dollars (2,000+) due to finally getting my asthma deconized and I was in and out of the hospital with bronchitis and monochitas from may till just last month and I am getting sick again. My paypal is paypal.me/ericamedia and my wishlist links is here (x) These are my commissions at the moment, I might some more later!

Astrology – These tend to take a while to complete. I been studying astrology since i was young and started taking it completely serious within the last couple of years and I am extremely knowledgeable about many subjects about the stars and it been my special interstants on and off all of my life really. I take this very serious and I study and stay a student every change I can

Full Natal Charts – Forty plus dollars ($40+) These are very limited and they take me a WHILE to completely. They are extremely detailed and I try to go over everything I can with these.

General Full Natal Charts – Twenty-five dollars ($25) These are not as limited as the FULL full natal charts as they are not AS detailed as them. They are general descriptions of everything I see in your natal chart.

“First Glances” – Fifthteen dollars ($15) This one is for three (3) to five (5) aspects, signs, houses, or planets you can pick them out or you can let me pick out the ones I see espilley for uniqueness if you want. These are detailed and do not take me as long to completely, if you want to know about more than five (5) aspects but do not want a full natal chart you can add on more aspects for two-fifty an aspect ($2.50)

Mupitable Tranists – Twenty to Twenty-Five Dollars ($20-25) I do six (6) max for these as I said astrology is my passion but it takes a while to complete, but with the transits I have to completely fast, these are limited too.

Some Transitions –  Ten dollars ($10) I do three (3) max for these and the above goes with this one. Not as limited as the Mupitabled.

Compatibility – Twenty-five dollars ($25) These are not as detailed as my others, I love to do compatibility but at the same time I can not fully encouraged theses because a lot of newbies and people not as serious into astrology take them a bit too serious so I leave these more general. These can be good for parents-children, siblings, romantic and planctioc pattereans, even celebrities because let’s admit it, it’s fun to see!

Full Body Clean Sketches – Five ($5)

Full Body Simple Colored – Ten ($10)

Poritions, Simple – fifthteen ($15)

Specialized Readings – Vary, direct message me and we can talk and figure it out!

Nudes – I am going to admit, I hate these and I charge extra due to this being my main. I also do not do custom clips or videos, only role-playing and pictures because I do not have the wifi or ability to do anything else. I expect the full amount of money to be taken in account with these.

I used to think i didn’t have any triggers. I’m an abuse survivor and i really thought maybe i came out of it just fine with no triggers.

Then a man slammed his hands on the desk beside me in frustration, he wasn’t angry at me he had just messed up something he was doing.

I froze, like literally froze, then tears started streaming and i was shaking. 

I was so fucking upset and distraught, all i could manage to get out was “I didn’t like that.”

My body had a really surprising reaction and i guess i’m not as over my abuse as i’d like to think sometimes. I’m making this post to tell others things like this, triggers, they can pop up at any time. 

Try to be patient, and understanding when someone has a reaction that you might not understand. 

If you’re the person who was triggered, be patient with yourself. 

Don’t be like me and blame yourself for overreacting.

 Now i realize what it was that happened to me, and i’ll try to be better with myself in the future, and not blame myself immediately after.

It’s also possible to not even understand this are triggers. I used to think I just had “sudden mood swings” without realising the common thread because I was so deep into denying myself as a victim I couldn’t even recognise my own trauma.

They can appear long after trauma, they can be hard to recognise and it isn’t your fault.

it’s seldom difficult to tell when a party of grey-crowned babblers is in the vicinity. Their scolding, whistling and chattering calls readily give their presence away, but their most well-known call is a distinctive ‘ya-hoo’, given as a duet by pairs of birds –the female gives a harsh ‘ya’ and the male responds with a high-pitched ‘hoo’, though given the precise timing it sounds as though the call was given by a single bird.

This year seems like it doesn’t want to be good for us.

On Friday night, suddenly this little girl didn’t want to eat and seemed off (until the previous day she was normal).

Yesterday (Saturday) I went very early to the vet, they made blood tests and an echo.

The prognosis wasn’t life-threatening up until now, I have just received a call from the vet to tell me about her second blood tests and NOW it is life-threatening, the doctor even told I have to go tomorrow and leave her hospitalized.

I truly do not have enough to pay for all of this, it is too much too soon.

Please, please, if you can help me, even 1$ will make the difference!

This is my PayPal: https://www.paypal.me/catsinvenezuela

Help me save her life, I’m actually begging you, if you can’t donate, please share.

“Not all straight men like women” is still one of the funniest things I have read on this hellsite

elphabaforpresidentofgallifrey:

what the fuck

It actually does parse logically, if you consider the straight men who are sexually attracted to women and at the same time do not in clear demonstrable fact and often by their own admission ‘like’ women as entire beings who have brains as well as boobs and are occasionally too sick or busy to make dinner.
