OSCAR CARLSSON (1928 – 2017) Inventor of the Sholapur Hand Pump (basis of the India Mark II Pump)

by Ruper Talbot

Oscar Carlsson, famed designer of the Sholapur hand pump on which the India MK II is based, died in Sweden on January 18th aged 89. Ingrid, his wife of some 60 years, a teacher and social worker, died four months ago.

Oscar’s funeral will take place in his home town of Kristianstad, southern Sweden on February 11th.

Oscar and Ingrid worked together for many years in Sholapur, Maharashtra State, western India, under the auspices of the Mission Covenant Church of Sweden and the Hindustani Covenant Church.

Oscar Carlsson was a rare being, blessed with out-of-the-box imagination and clever engineering skills that he translated into practical solutions to every day technical and social problems. The Sholapur hand pump was perhaps his greatest contribution to improving the lives of rural people, his efforts magnified many times over by the mass produced India MKII.

From technical, trade school teacher in Sweden to managing the Sholapur Well Service in India, Oscar quickly adapted to his new environment, sharing his engineering expertise and teaching workshop practice and draughtsmanship while dreaming up better water lifting devices for the bore wells drilled by his project in the hard basalt of Maharashtra. It is with hand pumps that Oscar’s name is most closely associated.

Unicef is sometimes wrongly credited with inventing the India MKII hand pump and designing it from scratch. While it is true that the pump would not have seen the light of day without Unicef, it is also true that without the pioneering work of the NGO community in Maharashtra, especially Oscar Carlson with his Sholapur pump, there would not have been a MK II at all.  Apart form the pump itself, Oscar devised ball valves for the pump cylinder and a sand trap in the rising main to extend the life of (the then) leather cup washers, amongst many other ingenious ideas to improve efficiency and longevity, all of this, back in the 1970s.

His pivot mechanism for the pump handle, which cleverly avoids lateral stress to the bearings, and his chain and quadrant to maintain alignment and keep the connecting rods in tension that he designed nearly 50 years ago, remain virtually unchanged in the MKII. There are several other features of the pump that still carry Oscar’s imprint and he was pleased with the association, (though he never quite forgave Unicef for not incorporating internal handle stops to prevent crushed fingers in the final design).

The Sholapur hand pump laid the foundation for the India MK II development programme and it was Oscar’s inventive genius and the magnanimity of the Sholapur Well Service in freely sharing his ideas that enabled this to happen.

In recent times, I spent several days each year with Oscar at his home in Kristianstad, reinventing hand pumps (as one does) and debating solar water pumping as The Next Big Thing. Oscar became fascinated by solar. We investigated tracking devices to optimise the use of costly solar panels and purchased a sophisticated German tracker to figure out how it worked. Oscar then cobbled together a design of his own from an old VW windscreen wiper motor and other bits and pieces lying around in his work shop, and set up a test rig on his garage roof to compare performance, correlating his findings with theoretical readings back in India.

And then, a couple of years ago, when he was well into his eighties and we had become alarmed at the plummeting water tables in India’s hard rock areas, he worked on a diaphragm operated cylinder attachment to make pumping easier at depth. I was to have field tested this in India last year, but sadly, time was not on our side.

Oscar was always thinking of something new and never stopped working at his drawing board or with a newly acquired CAD programme, until last year when Alzheimer’s began to take its toll, and then cancer took hold…

These days, it is fashionable to decry the efforts of NGOs and mission based ‘do gooders’. But amongst them are some rare gems. Oscar was one such from the early days of rural development. The 6 million or so MK II hand pumps in India and the thousands more in other countries are a magnificent tribute to Oscar’s engineering prowess and timeless, practical designs. It is something of a tragedy then, that many manufacturers today use inferior material and ignore the specifications and quality norms so critical to the reliability of a MK II hand pump (or anything else for that matter).

Nevertheless, countless rural communities still benefit from Oscar’s creative mind, So, on behalf of them all and on behalf of his many friends and admirers around the world, let me just say, thank you Oscar. Yours was a most useful and valuable life, well lived.

RIP

Oscar Carlsson was the first to be designated as Swede of the year Abroad. It happened in 1988 when the Swedes Worldwide celebrated its 50th anniversary.

Self-supply highlights from 2016

We are well into 2017 already, but it is still a good moment to look back to some highlights of 2016 from the point of view of Self-supply:

  • In the first half of 2016, the UNICEF-funded studies of Self-supply in Zambia and Zimbabwe were completed. The studies showcase these two experiences at scale, and they are the fundament for making an economic case for Self-Supply , demonstrating that using Self-supply as part of the strategies to reacp1430235h full coverage can be very cost-effective.
  • In Addis Ababa, Ethiopia, a 2nd national meeting on Self-supply was organized bringing together dozens of national stakeholders involved in the scaling up of Self-supply at country level through the national ONE WASH Programme.
  • The 2016 edition of the WEDC conference also saw its share of Self-supply: A paper presented by Annemarieke Maltha (on experiences of the SMART Centre approach in Tanzania) and one by Sally Sutton on the experiences in Zambia, among others.
  • The RWSN mini-series of webinars in the autumn 2016 included an event on Self-supply, focusing on the economic analysis of country strategies in Zambia and Zimbabwe (see recordings of the webinar here).
  • Self-supply also made a splash at the 7th RWSN Forum in Abidjan (29.11 – 03.12.2016), with 7 sessions related to Self-supply (see a list of Self-supply papers here). Apart from the frequent appearance of the Self-supply Theme in the sessions it also was notable to see how often the term came up in discussions and in plenary speeches, including within the panel of the closing ceremony.
  • At the same event, a bottom-up, spontaneous initiative of a small group of people helped to engage in conversations with many of the participants of the Forum and resulted in 150 signing a paper confirming their personal approval and support of the Self-supply approach.
  • As one possible way of implementing Self-Supply, the initiative of SMART Centre Group emerged and gained traction throughout the year. SMART Centres are business incubators which foster the local private sector in the WASH sector. Currently, there are SMART Centres in 5 countries formally recognized as such (see smartcentregroup.com), but many other organizations are implementing similar concepts around the world, and it will be interesting to see how these different initiatives can support each other and create synergies – or even merge – in the future.

Overall, it has been a fantastic year for Self-supply. Especially if we consider that the term “Self-supply” did not even exist before 2004 (when it was created by RWSN), it is remarkable that after a relatively slow process of foundation building we are now witnessing the moment when Self-supply is getting into mainstream – and hopefully we will see a wider use and further development of the concept in the near future. On behalf of RWSN, and particularly Skat as the lead agency for the Self-supply theme, we are encouraged by the results achieved so far and look forward to the next phase of development – and to another year of progress, exchange and learning with our RWSN partners.

Happy New Year RWSN Members/ Bonne année à tous les membres du RWSN!

  (texte en français ci-dessous),

 As we gear up for action at the start of the year, allow me to wish you a very joyful and productive 2017! The Rural Water Supply Network (RWSN) is a network, and this could not have been felt more strongly in the preparations for the 7th RWSN Forum and the event itself.  The Forum in Abidjan, Côte d’Ivoire at the end of 2016 witnessed vibrant exchange between 450 participants from over 60 countries. There were 40 different sessions, not to mention numerous informal networking opportunities.

Making rights real by supporting local government heroes

re-posted from: http://www.wateraid.org/news/blogs/2016/december/making-rights-real-by-supporting-local-government-heroes

Louisa Gosling, WaterAid’s Quality Programmes Manager, introduces a guide to using the status of water and sanitation as human rights to drive progress on the ground, and explains how marketing strategies can help us reach our target audiences.

The UN officially recognised the human rights to safe drinking water and sanitation in 2010. But what does this actually mean for work on the ground?

For people living in rich countries, where heavily regulated utilities supply the population with water and collect and treat wastewater, rights to water and sanitation are mainly covered by enforceable domestic laws and regulations.

Independent inspectorates and complaints mechanisms ensure service providers can be held accountable to service users.

But for people living in countries with very poor access to water and sanitation services, it is a different picture. For the nearly 2.4 billion people without access to adequate sanitation, and 663 million without access to clean water, these systems are often not in place. The lack of access is due to lack of capacity and resources in the sector, weak demand by service users, and poor accountability of service providers to users – their rights are neither demanded nor fulfilled.

The human rights framework clearly assigns responsibilities – people have the rights to water and sanitation services, and governments are duty bound to realise them. But what does that mean in practical terms for government, especially local government officials, who are closest to the people? How can the human rights actually help local officials to reach everyone, even when they have very limited resources and capacities?

With more countries integrating human rights to water and sanitation into national systems there is an opportunity to explore the difference this can make to both providers and users of water and sanitation services.

Making rights real – a guide

The UN Special Rapporteur’s handbook on realising the human rights to water and sanitation sets out the practical implications in considerable detail, which is helpful. But it is too long and detailed for many practitioners to use. So, WaterAid, WASH United, End Water Poverty, University of Technology Sydney, UNICEF, and the Rural Water Supply Network joined forces to develop guidance specifically aimed at local government officials. We worked with a content marketing agency, C3, to help make a really user-friendly guide.

Content marketing is customer centric communication. Understand your audience and their needs, and to be serious about it. What can we sell "them" today? What are you interested in right now?

A marketing approach

To find out more about our target audience the ‘Making Rights Real’ project partners, funded by players of the People’s Postcode Lottery, carried out an audience analysis. First, we interviewed local government officials in low-income settings to learn what they thought about their responsibilities for reaching everyone everywhere with water and sanitation. We wanted to know what helps them, what makes their work difficult, and what can help to inspire them. We presented the resulting paper – ‘Achieving universal and equitable access to water, sanitation and hygiene (WASH) for all – practitioner perspectives and perceptions [191]’1 at the Rural Water Supply Network forum in Abidjan.

The report clearly showed the many challenges that local government officials face, and their low understanding of human rights as something relevant to their work.

So, working with C3, we used these interviews to develop user ‘personas’ to help us better target the content of human rights to our audience.

Would-be heroes

We decided to target our materials towards the would-be heroes. The analysis defined this audience segment as a large group of people working in local government, who feel personally committed to providing services to local people but are constrained and thwarted by lack of resources and political support.

We agreed that if this group were empowered and supported some of them could become superheroes and really help progress. Champions within institutions can have a huge impact. For example, the WaterAid-commissioned research ‘A tale of clean cities’ found that one of the main drivers for improving urban sanitation was committed champions at the municipal level.

The would-be heroes have many misconceptions about human rights. For example, they often believe that if water is a human right it should be provided to everyone free of charge, which is clearly incompatible with governments needing to raise revenue to help run sustainable services. However, the human rights standards state that it is fine to ask people to pay for services, as long as the tariffs are affordable.

We also discovered the many different groups that influence the would-be heroes’ actions and decisions (see image 4). We learned how important it is to recognise these influencers, to galvanise as much support, advocacy, and collaboration as possible from them in order to achieve adequate and sustainable services for all.

Who influences the would-be hero?

We wanted to create a guide to help support and nurture sector champions. To clarify to local government officials the usefulness of human rights thinking, we used the analysis to design a colourful three-piece guide – ‘Making Rights Real’. The idea is for sector partners (like WaterAid) to use the materials in conversations with government partners.

The guide comprises: the pocket guide, containing basic thoughts and principles; the manual, with each step explained; and the journey, which shows the process at a glance.

You can download the guide (currently in English, French, and Portuguese) and instructions, from the Rights to Water and Sanitation website, and use them in your working relationships with governments.

Rights at the RWSN Forum

We launched the materials at the Rural Water Supply Network Forum (RWSN) in Cote d’Ivoire, using presentations, discussions, and role play. The response from participants was very promising. There is a strong desire among people in the sector to know more about human rights and how they can use them to clarify responsibilities of governments, communities, service providers, and service users, and make everyone more accountable to provide adequate and sustainable services for all.

If we are to reach everyone everywhere with access to water and sanitation by 2030, as promised in the UN Sustainable Development Goals, a change in approach is needed. These essential human rights can only be delivered if those with the duty to deliver them are empowered and inspired to do so.

Can Self-Supply Save the World?

Some highlights from the RWSN Forum and thoughts on 12 years of a learning journey, by Matthias Saladin, Skat

Of course the title is a rhetorical question – no one really expects one specific approach to transform the whole water sector, let alone save the world. Nevertheless, Self-supply as a concept is gaining traction and prominence in the sector as I witnessed during the 7th RWSN Forum, which took place from November 29 to December 02 in Abidjan. Just a couple of years ago, the term “Self-supply” did not even exist. In fact, it was coined within RWSN as part of a strategic planning exercise in 2004, where Self-supply was defined as one of the flagships of RWSN. Of course, people providing water for themselves (“Self-supply”) is a process which has been going on for millennia and all over the planet (for example, some 44 million people in the US today rely on Self-supply for their drinking water), but Self-supply as a term was born in 2004, and the idea that this approach can (and should) be fostered by specific activities and frameworks both by government and other actors still is relatively new to many people, even within the water sector.

In this blog entry, I would like to reflect on some aspects of this learning journey of the past 12 years, and I invite you to reply, discuss, disagree, criticize or support, whatever suits you best.

Flashlights on Self-supply at the 7th RWSN Forum

But first things first: The 7th RWSN Forum was a massive success, both in terms of participation and outreach, but also specifically for the Theme of Self-supply: I identified at least 7 sessions where papers related to Self-supply were presented, some of which I was not even aware of before the Forum. For example, Sara Marks of Eawag (Switzerland) presented some results of a study from Burkina Faso (feel free to read the respective paper and presentation) where they looked into the various benefits of a project implementing a (subsidized) Self-supply approach to facilitate multiple-use water services (MUS). Among other things, they found that the water of households who had invested in an upgraded private well and equipped it with a Rope Pump was of better quality than that of unimproved wells.

Meanwhile, session 6A was designed to provide an update on the “state of the art” in Self-supply, including an overview paper of André Olschewski, a case study from Sally Sutton on Self-supply in some African countries, an overview of how Self-supply can be accelerated in Ethiopia, and an example of how capacities in the private sector can be strengthened through SMART Centres (or watch the movie on the SMART Centre in Zambia here).

In several other sessions, specific aspects of Self-supply were analyzed in more detail, for example by Patrick Alubbe of water.org, who made a case for micro-credit as a scalable intervention who can help more people gaining access to higher level of drinking water services (see the paper of Gupta and Labh and Patrick’s presentation).

Making a Splash – and causing allergic reactions

Apart from this wide and deep presence of Self-supply in the thematic sessions, the concept also made a splash at key moments of the RWSN Forum: For example, it was prominently mentioned by the final remarks of Mr. Jonathan Kamkwalala, a senior manager of the World Bank, during the closing ceremony. Moreover, more than 150 people signed an informal “Call to action”, which suggests that Self-supply deserves more attention on behalf of governments, donors, civil society organizations, researchers, and other key players. The undersigned expressed a “strong interest in developing support for Self-supply within our own spheres of activity and urge all development partners to explore this approach and reach its considerable potential”. Given this strong support by a large number of people, I hope that we will see a lot of action in this field in the weeks and months to come – for example by starting to monitor and report on Self-supply within organizations, regions,  and eventually countries and globally. As we know, we do not manage what we do not measure, so measuring definitively would be a good start.

In spite of these highlights and an overall strong presence of Self-supply during the Forum, not everything is rosy in regard to Self-supply. On one hand, I observed that while many people recognize the important role Self-supply already plays and will have to play to reach the SDGs, with another group of people it creates almost allergic reactions. Having listened to some of these people, I think I identified three areas of conflict, which are related to three misconceptions around Self-supply:

1.       Self-supply means abandoning the poor.

2.       Self-supply means that government has no role to play.

3.       Self-supply is incompatible with the Human Rights to Water and Sanitation.

For the moment, I will only respond to the third misconception.  It can readily be clarified, simply by listening of the presentation of the UN Rapporteur on the Human Rights to Water and Sanitation during a webinar hosted by RWSN last year (e.g., read this summary), where he makes it clear that Self-supply is in line with the progressive realization of these Human Rights. And this hint also helps clarifying the first misconception: Self-supply does not imply abandoning the poor, but supporting them in a different way – rather than the government itself providing services, it facilitates and strengthens the private sector (and civil society organizations) to provide them. Thus, rather than abandoning the poor, what Supported Self-supply does is actually empower them and enable them to take on a more active role in moving up the ladder of water services.

Importantly, the Government has to play a role in Supported Self-supply – in fact, it is a crucial role consisting of several functions (adequate policy framework, building up capacities, oversight of the private sector, etc.), but this will be the topic of my next blog. So for the moment, I leave it there, confirming that the Government is a key actor in Supported Self-supply.

Striking a balance

Overall, the concept of Self-supply clearly has an important role to play if we want to provide some (even if it’s just basic) level of services to everyone – there simply is no alternative in reaching specific target groups, especially in the remote rural areas. However, we also have to be aware that Self-supply has its limitations, and that there are aspects related to Self-supply which have to be addressed with a lot of care (e.g., quality of the services installed, potential over-exploitation of water resources by private households). I also perceived that several people and organizations are looking for shiny examples of countries where Supported Self-supply was implemented at scale, which then could be replicated elsewhere (the “Blueprint Fallacy” which unfortunately is quite common in the water sector, particularly among global players).

However, at the moment there are only a few such examples (e.g. manual drilling in Nigeria/Lagos, Domestic Rainwater Harvesting in Thailand, the Upgraded Family Wells in Zimbabwe), and many of these cases refer to contexts where government services were weak or collapsing – which do not make for a good example for promotion, particularly with government agencies. With all due respect, but which government agency would like to copy the experience of Zimbabwe in the 1990s? Thus, the examples are not as shiny as we wish.

Nevertheless, the fact is that Self-supply actually took off in some places while government services, institutions and the whole economy was collapsing – a clear hint to the power of this approach, even under difficult conditions. But we also need to figure out how governments can foster the approach – that is, how to better Support Self-supply.

The way forward

In spite of all the progress made I think there still is a lot of work to be done both within RWSN and beyond. Here are just a few areas of work a group of “Self-Suppliers” identified during an informal conversation at the Forum:

  • Revisit the basic terms, definitions and concepts and make them more intuitive to understand.
  • Help people, particularly within government and funding agencies, understand better the key role government has to play to support Self-supply
  • In cooperation with research institutions, improve our understanding of the potential and limits of Self-supply, and the variety of benefits it can generate (not only in health, but also in productivity, income-generation, equality and non-discrimination, inclusiveness, well-being, cost-savings to government agencies, etc.).
  • Keep up the dialogue with people and organizations who think that Self-supply is a nightmare and should be hindered wherever possible. Their arguments will help us guide future research and for making a better case where and why Self-supply has a role to play.
  • Engage with actors (particularly non-profit organizations) who undermine existing and flourishing markets by giving away stuff for free. Giving away products and services for free is not Self-supply, does not build up capacity with anyone and damages existing supply chains.

Thus, looking back to the first 12 years of promoting Self-supply, I think we have come a long way. Given that before 2004 the term did not even exist, the change is truly remarkable – and RWSN was the lead agency of making this sea change in public awareness possible. At the same time, we still need to work on the fundaments, the walls and the windows of the Self-supply house, and we need to make them strong enough to keep growing in the coming 12 years and beyond. I hope that many of you will be part of this journey, and I invite you – as a small first step – to subscribe to the Dgroup on Accelerating Self-supply, which is a platform for discussion, exchange and mutual learning, and to contribute to the dialogue on that platform. I look forward to hearing from many of you there!

Onwards and Upwards,

Matthias

Quelques astuces pour une exploitation des eaux souterraines réussie: séminaire sponsorisé au 7ème Forum du RWSN, Abidjan

Vous exploitez des nappes phréatiques pour améliorer la desserte en eau des zones rurales? Venez participer à cette journée de séminaire et découvrir comment utiliser les eaux souterraines pour établir des systèmes salubres et durables d’approvisionnement en eau. Nous y aborderons nombre de sujets liés à l’exploitation des eaux souterraines, des informations et des données nous permettant de mieux comprendre ces ressources particulières aux technologies de construction des forages et des pompes solaires qui facilitent la mise en oeuvre d’un approvisionnement en eau efficace.

Quel intérêt ai-je à participer à ce séminaire?
Ce séminaire d’une journée – une approche intelligible de l’exploitation et de l’utilisation des eaux souterraines – dissipera certains des mystères qui entourent encore l’exploitation des eaux souterraines. Il vous fournira aussi des informations pratiques et utiles pour vous aider à mettre en place des systèmes d’approvisionnement en eaux souterraines efficaces.

Les eaux souterraines représentent 30% des réserves mondiales d’eau douce, et plus de 95% de l’eau douce non glacée disponible. Du fait de leur bonne qualité globale, de leur répartition géographique très étendue et de leur résilience aux fluctuations saisonnières (par rapport aux eaux de surface notamment), les eaux souterraines peuvent constituer une source d’approvisionnement en eau salubre, durable et bon marché pour de nombreuses communautés.

Les eaux souterraines sont parfois appelées des atouts cachés – elles se trouvent sous la surface donc il n’est pas facile de les voir ni de se les imaginer, et la multitude de facteurs qui influencent leurs formations et leurs évolutions (la géologie, la topographie, le climat, le type et l’utilisation des sols, et même les activités humaines) font que leur fonctionnement est souvent difficile à comprendre.

Qu’est-ce que je vais y apprendre?
Nous devons mieux comprendre les eaux souterraines si nous voulons les exploiter de façon sûre et durable. Or pour les comprendre nous avons besoin de données et d’informations fiables, qui sont souvent difficiles à trouver.

La première moitié de ce séminaire répondra donc aux questions suivantes:

  • Quelles sont les données et les informations nécessaires pour bien comprendre les eaux souterraines et pour les exploiter de façon durable?
  • Comment pouvons nous efficacement collecter et stocker des données sur les eaux souterraines afin de constituer une banque d’information d’excellente qualité qui soit accessible, pratique, bon marché, facile à gérer et utile pour les projets d’exploitation des eaux souterraines en cours et à venir?

Nous allons examiner les données obtenues à différentes échelles – depuis les initiatives internationales jusqu’aux données locales de sites spécifiques – et nous nous concentrerons sur le niveau national avec la présentation d’une part de l’Atlas des eaux souterraines en Afrique et d’autre part d’études de cas de dispositifs nationaux en Afrique de l’ouest de collecte et de stockage de données sur les eaux souterraines. Les participants auront l’opportunité de mentionner les problèmes et les enjeux liés aux données sur les eaux souterraines (la collecte, le stockage, la gestion et l’usage) qu’eux même rencontrent dans leur pratique professionnelle et nous essaierons de leur proposer des solutions pragmatiques pour l’avenir.

La deuxième moitié du séminaire sera consacrée aux aspects pratiques de l’exploitation des eaux souterraines pour montrer comment des solutions adéquates en terme de construction des forages, et de pompes et de distribution solaires peuvent créer les conditions d’un accès à une eau salubre rentable et durable pour celles et ceux qui en ont le plus besoin.

Nous présenterons comment certaines méthodes de construction et d’entretien des forages peuvent à la fois fournir un approvisionnement en eau potable dépourvu d’E. Coli et qui durera sur plusieurs générations, et contribuer à la protection des sources d’eaux souterraines. Les participants recevront également des outils et des conseils méthodologiques pour la rédaction des spécifications techniques des forages afin de s’assurer que les sources d’eaux souterraines soient salubres et durables.

De la construction des forages nous passerons ensuite aux technologies de pompage et de distribution solaires, en montrant que cela représente souvent une option avisée et viable pour la fourniture de services ruraux en eau potable, en particulier lorsque la mauvaise qualité des eaux souterraines ou qu’une forte densité et croissance démographique limitent les possibilités d’utiliser des forages équipés de pompes manuelles. Nous présenterons plusieurs études de cas allant des points d’eau isolés aux réseaux de distribution centralisés et ayant toutes de faibles taux d’échec et des coûts de cycle de vie très limités. Nous en tirerons une série d’enseignements sur la conception, la construction et la mise en œuvre des systèmes d’approvisionnement en eau fonctionnant à l’énergie solaire.

Qui devrait participer à ce séminaire?
Toute personne intéressée par les services en eau dans les zones rurales, et en particulier par les thèmes des eaux souterraines et de l’approvisionnement en eau. Nous espérons accueillir une grande variété de participants appartenant à différents types d’organisations et à différents niveaux de responsabilité – Etats, ONGs, secteur privé, praticiens et universitaires.

Qui présentera le séminaire?
Le séminaire est sponsorisé par le programme de recherche UPGro (Libérer le potentiel des eaux souterraines pour les populations pauvres) et Water Mission. Il sera présenté par plusieurs experts africains, européens et américains des eaux souterraines.

Quand et où aura-t-il lieu?
Vendredi 2 décembre, 7ème Forum du RWSN (salle Bamako), Abidjan, Côte d’Ivoire

Le séminaire sera présenté en anglais avec une traduction simultanée, et des facilitateurs francophones et anglophones seront présents tout au long de la journée.
