E também vai instável, ontem íamos dormir ao relento mas desistimos porque veio nevoeiro.
Ainda temos água para regar, mas há quem diga que não chega até ao fim de Agosto.
Entretanto, já comemos imensos kilos de amoras da linda e grande amoreira do florestado quintal, e outros tantos de framboesas.
Estas têm a particularidade de ficarem fantásticas em sorvete. Já acabaram as framboesas e os sorvetes :(
Mas vamos poder comer delas durante o inverno porque temos doces feitos com amoras, framboesas, groselhas, mirtilos e tudo misturado...
Com a seca, as amoras das silvas não estão a medrar, há algumas mas poucas.
Já comemos alperces e pêssegos, estão a chegar as ameixas e os figos, que já vamos comendo aqui e ali.
Deixámos de fazer queijo, por causa do calor e bebemos leite de cabra ao peq almoço e ao lanche.
Andamos a comer das nossas espigas de milho cozidas, barradas com manteiga.
As cabrinhas já estão "grandinhas" e está a chegar a alturas das suas mães emprenharem outra vez.
Entretanto chegou à "quinta" um porco, o Jeremias, que se tem deliciado com as batatas velhas, porque para nós já começámos a apanhar das novas.
Hoje começaram a nascer os pintainhos, já vi 2, faltam nascer 7.
Apanhámos o centeio todo, as favas (7kg) e as ervilhas (15kg) , mas ainda temos tremoço e tremocilha para apanhar.
As alfaces espigaram muito cedo, mas temos muita beterraba.
As courgettes e os pepinos já têm dado mas os pimentos e o tomate só vão começar agora a dar.
O feijão verde não foi tão forte como o ano passado, mas vai haver muito feijão seco para debulhar.
Os cogumelos já deram e já os acabámos. São bons!
Andamos a apanhar folhas de "quase tudo" para secar e fazer chá, temos cada vez mais variedade.
E assim vai a "quinta"!
When there's no toilets in a community people "go" in the open, behind bushes, buildings, wherever they can find. If you visit lots of villages you soon get that whiff of exposed poo, and if you spend a bit of time with that community you get to understand what happens when people are in such close and regular contact with their "wastes", from the high levels of diarrhoea and a host of other water borne diseases they live with (and pay for in money for medicines and visits to distant clinics).
It's clear: dirty, unsafe water is almost always a result of contamination from faeces and sewage. And this continues to be one of the biggest causes for under-5 mortality, especially where there are no toilets. This has to be fixed.
|This UNICEF poster I saw last week on a wall in Sindh pretty much says|
it all. Surely it's not rocket science, and yet getting people to change
these habits and practices is one of the most challenging I have come across.
I have seen this in countless villages and urban areas across Pakistan but also Liberia and other countries. Globally the numbers are staggering: some 2.5 billion people lack access to proper sanitation; 1 billion still defecate in the open - both of these are estimated to cause almost a million unnecessary deaths a year.
Emerging evidence is also proving that lack of sanitation could be one of the leading drivers of malnutrition globally. This powerful story in the New York Times explains it better than most, explaining how constant infection in the gut prevents children from absorbing nutrients - regardless of how much food or money they have access to. This causes chronic stunting whereby the body and the brain fail to reach their optimal potential, a process that can't be reversed; stunted children thus can't function academically, economically on a par with their peers. The implications this has on Governments in poor countries is staggering: address water, sanitation and hygiene or half your people will be half as productive and smart as they could be.
This gets me thinking about recent trends from donors / banks to promote cash transfers (dubbed "social protection" or social safety nets). Billions of dollars are spent this way, and there's strong evidence to support that it works in some settings. But if water and sanitation aren't addressed in parallel... then these underlying drivers of vulnerability will just remain in place.
Other studies have looked at the economic costs of this shitty situation. In Pakistan it is estimated that poor sanitation costs the country some $5.7 billion annually in economic losses; while in India, which has the highest numbers of malnourished children in the world the losses are equal to a dizzying $54 billion - per year!
Thinking back to my time In Liberia, during the peak of conflict in 2003 (managing health agency MERLIN's emergency response), when half a million people fleeing the rebel attack poured over to "our" side of the city, as the country's biggest cholera epidemic in years was killing far more than the bullets and bombs. We set up a lot of cholera treatment units, water tanks, toilets, and saved many lives, for sure, but had there been adequate treatment in place already, I'm starting to think it could have reduced so much mortality. Note to self: find out how much of cholera-endemic Liberia remains without adequate sanitation and get writing to the Government!
But it's not just OD, it's also the scourge of untreated sewerage which seeps out of semi-urban and urban communities across Pakistan (and in so much of the world). This stinky sludge ends up contaminating our fresh water sources, killing off other plant and fish life, creating weird natural imbalances like algae blooms which when they die give off some other toxic liquid waste which is also really harmful, potentially lethal to fish, birds and humans.
So all in all, human waste is equal to untold suffering, disease, pollution and contamination for people and other forms of life. But - this is only the case if you don't treat it properly, if your systems for treatment isn't designed with full treatment in mind, or if it's only partially complete, which seems to be the case pretty much everywhere in the world I go.
Pit Latrines and treatment options
So... what are the options? Well first, it helps to understand the basics of the biology at play. Let's take an example of a pit latrine, it will hold the liquid and solids together in an underwater state which means that oxygen can't get in, so it's anaerobic. A multitude of harmful bacteria live in this state, which also produces loads of methane, and uric acid (from the pee) all of which smell bad. So if you step into one of these pit latrines you will want to get out as soon as possible. Really not ideal, but in an emergency, better than nothing when there are thousands of people living in a small area, and open defecation would be really dangerous for public health.
The alternative in this case is a compost toilet, which prevents the waste from becoming anaerobic by adding sawdust, straw, leaves or any dry thing (rich in carbon, crunched up cardboard will do). This absorbs a lot of the liquid and allows for little bits of air (thus oxygen) to get in and around the pile, which thus remains aerobic. A completely different, thermophyllic process kicks in whereby in heats up, pretty much like a compost heap. These are unique "heat-loving" bacteria which exist in any composting process; over time they reduce these natural processes eliminate the harmful germs and bacteria: they "treat" our wastes, making it safe. Moreover, it transforms it into a a really rich source of nutrients for plant growth. One of the best books, brimming with resources to understand all this is the humanure handbook.
In other words: The problem and source of so much disease and suffering has the potential to be a great resource for regenerating a denuded garden, tree planting, and so much positive growth.
Pour flush toilets and sewage treatment
The other types of toilets are the pour flush ones that most people living in cities or richer countries use every day. Squat plate or sit-on-top they both hold a bit of water to receive your delivery, then water is added and it disappears, through a U-bend into a septic tank where it sits in that same anaerobic environment discussed above. Millions of naturally occurring anaerobic tolerant bacteria in the tank consume the solids, changing it over time from solid to less dense and then floating scum, which then rise and leave the tank as more waste arrives.
Now, here's the gross and deeply unsettling part: septic tanks only partially treat this sewage. It is still highly contaminated and is known to be one of the largest sources of ground-water contamination. Bacteria, viruses, parasites (including worms and protozoans) are the types of pathogens in sewage waste and run-off from septic tanks. The bacteria can cause numerous diseases including typhoid, dysentery, gastroenteritis, cholera; the viruses meanwhile include such infamous horrors as polio, hepatitis A, viral gastroenteritis.
|Example 2: raw sewerage running through a semi-urban|
area of Jacobabad, Pakistan. These channels
are often blocked with garbage and overflow into the street.
Next stop: the nearest irrigation canal.
|Example 3. Another overflowing latrine (Punjab)|
another aid project, this time a good example
of the algae bloom, causing very hazardous
toxins. Is this any better than open defecation?
I have hundreds of examples; the point is that a septic tank alone does not treat the sewerage waste. Most designs recommend a soak-away pit. This is basically a hole in the ground filled with some gravel where the septic water seeps into, through a perforated pipe, or just straight into the gravelly hole. And then, into the ground, maybe into the ground-water, we don't really know. I've heard it said that soil acts as an excellent filter, but there's little research to show what happens when hundreds of households seep their waste-water into the same soil, it eventually builds up, and leads to contamination of ground water.
|Built by IDEP in Bali, this constructed wetland is only about |
18 months old and is seriously flourishing.
The water at the end of it smelled fresh.
The trees were growing at a phenomenal rate
These are gravel-filled sealed tanks, into which water-tolerant plants are set. There is no soil, only gravel. The roots transform the nutrients from the sewage waste (nitrogen, ammonia and urea) into plant growth. The roots oxygenate the water.

Thanks to Florence Cattin for this photo and for so much valuable advice on the theory and practice of waste water gardens.
There are other wetland system too, like Jay and Clara Abrahams of biologic design, who build "wetland ecosystem treatment or WET systems". These too are remarkable and I have visited many of their installations in England. Jay points out these WET systems are not simple horizontal or vertical flow reedbeds; instead the WET systems use soil as the purification medium, not gravel as do conventional reedbed treatment systems.
|A small portion of a WET system in the South of England, mid-winter.|
from a quiet large institution, this treated
all sewage and grey-water wastes.
The waste flows from one pond to the other through the soil banks that separate each. The extensive root networks and living soils provide a living filtration process. Fish and ducks can be introduced. Larger, older systems are like forests, attracting birds and enabling the return of biodiversity and health to the overall environment. Moreover, these systems promote rapid growth of high value species which can earn the owner serious money. In this case willow is planted which is harvested and sold locally.
Lastly, there's biogas. Human manure has less potential energy than that of cows, but it is still an organic material and will produce methane. It's such an obvious way to get energy from waste, but I doubt it would perform very well if the sewage weren't combined with other wastes, like sawdust and chopped up food waste, from kitchens or fruit markets. We installed such a system in our home, described in this blog, but we haven't lived there enough since then to really learn from it. But there is copious evidence already out there; we are well passed proof of concept. Check this 2 minute video for one. Crucially, we now know that biogas digesters are very effective at treating harmful pathogens, though not completely, so care should be taken of the slurry emerging as a bi-product. Again, not a problem if properly designed at the beginning.
It's clear that ecological systems can treat our sewage waste if we allow it to: the problem becomes an opportunity - and part of a solution for another problem. We need to start making these links.
It need not cost much more than we are currently spending, if we adopt the right designs, for which we need more testing, experimentation and research. Last week I joined a team from IDEP Bali who were teaching local NGOs in Pakistan how to build basic constructed wetlands - so we can start to learn from these results soon.
|An earth bag school under construction in Nepal, before the|
earthquake. This one, a school, built by the local community with design and
training help from Edge of Seven, others shown below.
Critical points are: these are extremely earthquake resilient, energy efficient
and require a fraction of the logistics of importing bricks and cement up the damaged roads, etc.
The incredibly powerful earthquake which struck Nepal on 25th of April this year has killed over 7,500 people and injured at least twice as many. Latest reports are indicating that over 255,000 houses have been destroyed, with another 215,000 "damaged". Humanitarian coordination is already up and running and huge amounts of data and information is being placed online and updated regularly. The relevant entry point is here.
The suffering and loss reported by the media and humanitarian agencies has been immense, unbearable for those families worst affected. Save the Children and UNDAC report
It reminds me of news, around ten years ago of the earthquake in Kashmir, Pakistan, which was actually slightly less intense than the one in Nepal (7.6 and 7.8 respectively, on the richter scale), but claimed more than 80,000 lives. At least, thus far, mortality in Nepal has been lower, by a a huge margin.
|The main sectors in the UN Flash appeal|
including target numbers of beneficiaries.
So there are lots of areas to deal with and to the extent possible the local Government NGOs (and a whole range of “civil society” actors will be leading the response). These appeals and the consequent scaling up of UN and international NGOs try, to a large extent, to support these local efforts, rather than overwhelm things with outsiders and foreign stuff.
With over a quarter of a million houses damaged, there's a massive shelter and housing challenge - that has to be addressed ASAP before the winter - indeed before the monsoon rainy season which can start as early as June and go through September.
- People need immediate (emergency) shelter now if they have lost their home and are sleeping out in the open or with friends and family.
- For those families who remain in or near their villages reconstruction and recovery starts right away. The concept of there being phases: emergency shelter, followed by some transitional affair, then “build back safer” durable and “earthquake compliant” shelter is not very close to their reality – or affordable.
- There will not be enough money. The UN has already asked for almost half a billion USD – for the first three months alone! (OK most of it for food and cash vouchers), but how much money do you think the donor community has to spare? (Don’t forget that the latest appeal to support Lebanon is for $2.2 bn, which doesn't include the needs inside Syria, Jordan, Yemen; let alone South Sudan, Ebola recovery and so on). So: whatever is done has to be extremely good value (read: low cost and robust). Or chose to support only a small percentage of the total caseload with a full price (all signing all dancing) reconstruction package.
- News update as of 8th May, the UN says it's only received about 5% of it's $415m appeal (that's around $22m). This usually happens at the beginning of an appeal, but 5% is really low, so, as I said, money is going to be tight.
- Immediate life-saving shelter interventions such as tarpaulins, basic tools and fixings for damaged homes for displaced people, along with the appropriate non-food items. (And the shelter cluster provides a pretty cool info sheet on how to strap down your tarp in the best way possible).
- Cash for the "most vulnerable" families (which in itself can be challenging to decide as so many have lost their homes and are vulnerable) to address urgent needs. Actually, I think that cash right now would be really useful and appropriate - assuming shops and markets are around. Much better than donating a tent or cooking sets, which cost a lot of money plus serious transport costs and hassle. People know what they need and they know how to get ahold of it, if they have money. However, I've also heard that building materials are really hard to buy right now and to transport to the more isolated areas. Moreover, cash alone doesn't pay for critical water and sanitation work to be done.
I heard from another colleague that it’s really difficult to buy or access materials out in the more remote areas; there’s not a lot of salvageable wood from the rubble and roofing sheets are damaged.
In which case - a really excellent resource - for anyone working with bamboo and tarps is this "reciproboo" system, developed by Shaun Halbert, which uses smart but really simple geometry to greatly reduce the amount of bamboo or sticks needed per shelter.
