Maps can be a great source of information, that is often used to target new research sites or for base-lining the new sites. The GGIAR megaprogram on climate change has produced an atlas for each of its study site.<br />

Above you can find the report for the site in Kenya (and <a href="http://ccafs.cgiar.org/atlas-ccafs-sites#.U0FBnfmSxCg" target="_blank">here the others</a>). The atlas always shows the particular site, but also the whole of Kenya.<br />

A great source of information not only for scientists but also for all those who want to plan an interesting trip to Kenya! ;-) </div>

I always have been interested in landscapes. When I was a boy, one of my favorites was the Upper Engadine Valley.<br />

Later, three trips have marked me a lot: (1) the National Parks in the U.S, in 1974, which has many nice landscapes but separated by huge distances, (2) the Nepal Himalaya in the Pokhara area in 1975 with its terraces and the snow covered Annapurna Massive behind and (3) the trip to eastern Europe (Eastern Germany, Poland and Latvia) in 1999 with its flat sand-dominated landscape (photo of the Land Brandenburg in the Berlin area, source: <a href="http://www.reiseland-brandenburg.de/themen/natur/nationale-naturlandschaften/naturpark-stechlin-ruppiner-land.html">http://www.reiseland-brandenburg.de/themen/natur/nationale-naturlandschaften/naturpark-stechlin-ruppiner-land.html</a>).<br />

Switzerland is well-known for its different lake- and mountain-dominated landscapes, separated by relatively short distances and it is base of tourism. The rapidly growing economy and population, in the last years, have put these nice sceneries under pressure (urbanization) to the point that tourists may want to pass their vacation at places where nature is better preserved and local people cannot afford anymore to live in the villages, <a href="http://catherinepfeifer.blogspot.ch/2013/06/secondary-residences-in-switzerland.html" target="_blank">because of very high land prices</a> (photo Zermatt area, source: www.nzz.ch)<br />

The reason why I bring up this subject, is that I recently ran accross several interesting publications on the subject, published by the <a href="http://www.bafu.admin.ch/landschaft/09591/index.html?lang=fr" target="_blank">Swiss Federal Office for the Environment (FOEN)</a>, the <a href="http://www.are.admin.ch/dokumentation/publikationen/index.html?lang=en" target="_blank">Federal Office for spatial development (ARE)</a> and the <a href="http://www.sl-fp.ch/index.php?bereich=english" target="_blank">Swiss Foundation for Landscape Conservation (SL)</a>. </div>

However as the following legends show, it is a rather complicated classification, which emphasizes altitude and slope angles too much instead of land use/cover (forest, agricultural plots, lakes etc.):</div>

The approach chosen by the SL (unfortunatley only available in <a href="http://www.sl-fp.ch/getdatei.php?datei_id=1216" target="_blank">German</a>) is much more attractive and is based on the concept of "cultural landscapes", based on the 6 main landscape elements ("textures") which dominate a given landscape: forest, type of agriculture, water, habitat, infrastructure and patrimony, providing the four important ecosystem services (cultural, natural, identification/ patrimony-creating, recreating). </div>

For each of these 6 main categories, up to 6 subtypes are presented, e.g. for the habitat: landscape with scattered settlements, village-dominated landscapes, periurban, suburban and urban landscapes, resulting also in 39 subtypes. But this classification takes important and obvious landscape elements such us rivers, lakes, hedges (German "Hecken") or parkways (allees) much better into account than the ARE classification:</div>

All of the agencies that published these different approaches underline their usefulness for planning and sustainable development. Especially the SL emphasizes an important aspect: often the general aims and the specific aspects to protect, when a given cultural landscape is included in an inventory such as <a href="http://whc.unesco.org/en/list/" target="_blank">Unesco</a> heritage or is declared protected by a local government, are not well defined. Being able to recognize important landscape elements and their <a href="https://www.blogger.com/">ecosystem service</a> is thus primordial (cf. article "The Concept of Ecosystem Services Regarding Landscape Research: A Review" by Hermann et al., Living Rev. Landscape Res., 5, 2011, 1).<br />

The ongoing climate change risks to change this picture during the next decades. Last summer in a butcher store in the village of Turtmann in the Wallis/Valais they sold melons from the area and certainly without particular intension they placed them under the picture of the Rhone glacier at the beginning of the 19th century, which at that time had its end close to the still existing Hotel "Gletsch" in the Goms valley, situated along the road leading ot the Furka Pass.

This very nicely written book is based on the personal experience of the two authors, as glaciologist (F.F.-S.) and forest engineer, mountain guide and head the division of natural dangers in the Valais-government (C.W.) respectively. It has been written (and the title translates this very well) to wake up the public and the politicians with the message: "Hey, do know that our very nice glaciers, which play an important role for our identity as mountainers, for the tourism and the energy production of our country, will most of them slowly disappear during the next 80 years ?"The following three graphs (source: VAW-ETH-Z cited above and the book) show the monitoring network of Swiss glaciers and the fact their length shortened between 10 and several hundred meters every year, especially during the last 20 years, in connection with the rising annual temperatures.<br />

This book, in between the scientific informations indicated on the table of contents shown above, presents <a href="http://www.myswissalps.ch/story/512">folk tales</a> related to the glaciers, revealing e.g. that it was believed that the lost souls of ancestors would live in them and that between 1600 and 1850 the catholic priests in the concerned villages, tried with processions and exorcism acts to make the glaciers (which advanced a lot during this so called "little ice age") retreat and that way avoid that pastures and forests would be destroyed, but with mixed success. During this period already (as in recent years), glacier lakes, that regularly owerflew, threatened the local population (example below dating from 2001 in Täsch, Matter Valley near Zermatt).<br />

This book reminded me of several important facts on glaciology and climate change predictions:
(1) Whether a glacier grows in terms of length or volume (which is more important than the former) depends at what altitude the socalled equilibrium line lays, i.e. the limit between the ice/snow accumulation zone (all year below 0°C) and the ablation zone where the ice melts, which depends on the mean annual temperature of each year. But the annual position of this line not only depends on the temperature, but also the amount of precipitations plays an important role. The important retreat of the glaciers after their maximum around 1856 seems mainly be more due to decreasing winter precipitations than to increasing temperatures.
However, for the years 1960 to 1980, when we had a lot of snow during winter time also below 700m in Switzerland, according to the temperature diagram above, the lower temperature could have been an important factor for the increase of glacier length during that period. The following two images of the Rhone glacier today and its evolution in length between 1900 and 2011 show: a) the limit between melting and accumulation in the back, where there is snow on the ice all year, whereas in the frontal part the grey ice melts during summer time and b) the length increase in the 1960ies (taken from the above mentionned VAW-ETH-Z-monitoring site).<br />

(2) This book also mentions import findings of researchers of <a href="http://www.climate.unibe.ch/~stocker/papers/joerin06hol.pdf">(Jöri et al. 2006)</a> on several even warmer periods during the Holocene with glaciers more retreated than today (based on radiocarbon and dendrochronological dating of wood and peat liberated by many glaciers today, <a href="http://www.permaqua.eu/de/news.asp?aktuelles_action=300&aktuelles_image_id=585016">Nicolussi 2012</a>). These findings do not at all disprove a human contribution to the actual global warming, as <a href="http://www.eike-klima-energie.eu/climategate-anzeige/gletscherrueckgang-in-den-alpen-aussergewoehnliche-bedrohung-oder-natuerliche-schwankung/">certain people</a> interpret these results. As it has been shown by <a href="http://edoc.hu-berlin.de/miscellanies/klimawandel-28044/27/PDF/27.pdf">H.Wanner</a> of University of Bern, these Holocene temperature fluctuations are due to very complex processes (among other the socalled Atlantic Oscillation). The following figure shows the findings of Jöri et al. (2006, <a href="http://www.eike-klima-energie.eu/climategate-anzeige/gletscherrueckgang-in-den-alpen-aussergewoehnliche-bedrohung-oder-natuerliche-schwankung/">source</a>).

(3) Aside from the changing landscape and the related loss of esthetic mountain views, this book shows that the main impact are of economic and ecological nature: With decreasing glacial volume it will be more and more difficult to fill the hydroelectrical power lakes and the lowland rivers, once the the snow melt will be over in June, will have a very reduced flow regime, threatening also Swiss agriculture (<a href="http://www.agroscope.ch/publikationen/einzelpublikation/index.html?pubdownload=NHzLpZeg7t,lnp6I0NTU042l2Z6ln1ad1IZn4Z2rZpnG3s2Rodeln6h1d354f4CNn,aknp6V2tTIjKbXoKimjZ2XmJaqiKfo">Fuhrer et al. 2013</a>).
(4) This book also mentiones that the actual predictions for the climate of the Swiss Alps depend on the gulf stream which influences the Atlantic oscillation and brings warm air to Europe. Should it stop, e.g. because of a much lower ocean salinity due to all the melted ice in the Polar region, than the climate in the Alps might become colder again, independant of the unavoidable arrival of the next glacial period during the next 5000 to 10000 years.<br />

As most of you know, I always have been equally interested in rocks and water. In this post I would like to show an interesting comparison between water supply techniques of the North (historical aspects) and the South (present day rural areas).
In Europe most old castles have dug wells of several tens of meters in depth. The oldest running fountains in European cities date from the 14-15th century. Mountainous settlements were supplied by springs or short aqueducts. But were did the water in flat rural areas came from? The origin of this question is a project on arsenic rich springs I had in the eastern Carpathians, Romania with a colleague from Cluj, during which I realized that still in 2005, the water supply of most farms in Romania was through picturesque sweep wells (dug wells with a genius balancing system, French: puits à balancier, German: Schwengelbrunnen; see also: short film on you tube:

Another personal experience (dating also back to 2005) was in Senegal, where in the urban agriculture area of Dakar, either simple shallow hand dug wells or deeper hand dug stonewall wells were also still in use for irrigation (in poor areas also for domestic needs).

The new thing for me was, that apparently up to 1900 also in Switzerland, in flat rural areas and even in some towns, hand dug wells with bucket winders or hand pumps were very common. But most of them, in the meanwhile have been filled up and covered.

In Switzerland, these witnesses of a type of water supply that has served mankind since Neolithic times are more and more found during constructions of new houses and are nowadays carefully preserved by the archeological service.<br />

In the South, in rural areas, this simple technique to supply water is still very important and there are many manuals published by NGOs engaged in development, how to dig a well avoiding risks (e.g. <a href="http://www.clean-water-for-laymen.com/hand-dug-wells.html">http://www.clean-water-for-laymen.com/hand-dug-wells.html</a>, <a href="http://www.wateraid.org/uk/~/media/Publications/Hand-dug-wells.pdf">http://www.wateraid.org/uk/~/media/Publications/Hand-dug-wells.pdf</a>) and in some northern countries with large rural areas, such as Canada, there are even new manuals how to construct hand dug wells (<a href="http://www.omafra.gov.on.ca/english/environment/facts/06-117.htm">http://www.omafra.gov.on.ca/english/environment/facts/06-117.htm</a>, <a href="http://www.env.gov.bc.ca/wsd/plan_protect_sustain/groundwater/gw_regulation/dug_wells_best_management-2013.pdf">http://www.env.gov.bc.ca/wsd/plan_protect_sustain/groundwater/gw_regulation/dug_wells_best_management-2013.pdf</a>)
With water prices climbing and climate change in the North, in the presence of shallow groundwater, it may become interesting to install a so-called driven well with a hand (pitcher) pump on top (German : Schlagbrunnen, fr. puits foncé) to irrigate gardens (

<span lang="FR-CH" style="font-family: "Times New Roman","serif"; mso-ansi-language: FR-CH;">Mon
premier contact avec le Prof Pfeifer a eu lieu dans le Vallon de l’Allondon à
Genève dans le cadre de travaux de terrain des étudiants du Diplôme d’Etude en
Science naturelles de l’Environnement (DESNE), c’était en octobre 2001.</span></div>
<div class="MsoNormal" style="margin-bottom: 12.0pt; text-align: justify;">
<span lang="FR-CH" style="font-family: "Times New Roman","serif"; mso-ansi-language: FR-CH;">J’ai
alors découvert un passionné de la nature, des sciences de l’environnement,
mais également un grand pédagogue, un formateur. A cette époque j’étais loin de
m’imaginer que je finirai par intégrer son laboratoire. En fait nous avons eu à
suivre ses cours et TP jusqu’à la fin de l’année (à Genève et à Lausanne, mais
aussi à Piora). Au moment de faire les mémoires, je suis tombé sur un sujet de
son premier assistant de l’époque, Dr Bernhard Dold. C’est ce sujet qui me
faire entrer dans son labo ou je passerai plus de 5 ans. Mon plus grand
souvenir et ma plus grande fierté d’étudiant ont été obtenus durant mon passage
à son labo. C’est prix de Faculté obtenu après ma thèse que la photo illustre.</span></div>
<div class="MsoNormal" style="margin-bottom: 12.0pt; text-align: justify;">
<span lang="FR-CH" style="font-family: "Times New Roman","serif"; mso-ansi-language: FR-CH;">Là,
je découvrais, au-delà du professeur, l’homme. Et cet homme m’a profondément
marqué par sa gentillesse, sa disponibilité, son amabilité. Il a toujours le
mot qu’il faut, les conseils nécessaires face à toutes les situations. Et il
est toujours là pour aider à trouver des solutions aussi bien pour le travail
que pour la vie privé. </span></div>
<div class="MsoNormal" style="margin-bottom: 12.0pt; text-align: justify;">
<span lang="FR-CH" style="font-family: "Times New Roman","serif"; mso-ansi-language: FR-CH;">Hans
Rudi n’était pas seulement un professeur, un maître pour moi, il est beaucoup
plus que ça. C’est un ami, un père car il a eu à se comporter avec moi comme
l’aurait fait un membre de ma famille. En effet lors que j’arrivais à Lausanne,
quittant la cité universitaire de Genève, c’est lui qui m’a prêté de l’argent
pour payer ma caution faire face aux urgences en attendant que mon contrat soit
signé. Ce geste<span style="mso-spacerun: yes;"> </span>salvateur est resté
gravé dans ma mémoire car, non seulement on en connaissait bien à l’époque,
mais il n’était pas tenu de le faire et il l’a fait avec bonté et a attendu
patiemment que je sois en mesure de rembourser. Je ne le remercierai jamais
assez pour ça.</span></div>

Rudi aime aider, rendre service, apporter son appui, son expertise à tous, mais
surtout à l’Afrique et particulièrement le Sénégal, mon pays. Beaucoup de
collaborations développées entre Lausanne et Dakar sont en grande partie dues à
son engagement et sa générosité. La dernière fois que je l’ai vu, c’était à
Dakar. Il animait un atelier dans la salle de conférence du Conseil régional de
Dakar sur la gestion des inondations ; et je voyais en lui la même passion
et la même disponibilité que quand j’étais son étudiant. La même semaine, je
passais le chercher dans son lieu de résidence pour aller ensemble chez notre
ami et collègue Seydou Niang et je souviens que ma voiture a chauffé en cours
de route. Tous ces moments son inoubliables pour moi. De plus il m’avait (il le
fait toujours) amené du bon chocolat Suisse.</span></div>

Ma
passion pour les sols m’a attiré vers des sujets que proposait le Prof. Pfeifer
pour mes travaux de Bachelor et de Master. De la théorie des pesticides dans le
sol - il m’avait donné le bouquin de Calvet et al. (637 pages) et m’avait
demandé d’en extraire l’essentiel (20 pages) - jusqu’à l’agriculture
périurbaine en Afrique, en faisant un détour par la décharge de Mbeubeuss, il
n’y avait pas qu’un pas mais j’ai sauté sur l’occasion. J’ai non seulement pu
découvrir le pays de la « Terenga » (hospitalité), la richesse d’une
culture différente… mais aussi appris à travailler en équipe et avec les moyens
du bord. Je n’oublierais jamais ce séjour enrichissant, durant lequel j’ai
découvert le côté très humain de mon professeur. Puis, après l’étude des
substances humiques dans les composts et fumiers, je suis revenu à des
molécules plus synthétiques (pesticides) pour quatre années (et quelques) de
doctorat, pendant lesquelles Hans-Rudolf Pfeifer était toujours là à me
soutenir dans mes recherches et à me conseiller dans cette aventure aux
multiples facettes.<br />

Hans-Ruedi, toi et moi, nous sommes
rencontrés à l'époque où ta carrière de géologue a commencé à prendre un
tournant nettement plus environnemental. J'ai toujours trouvé très
courageux de ta part de te lancer ainsi dans un "nouveau" domaine.</div>
<div>
Je
me souviens d'ailleurs de notre première rencontre à l'Eawag, lorsque
tu me disais que ce serait intéressant de venir à Lausanne.</div>
<div>
<br /></div>
<div>
Durant
notre collaboration lors du projet <a href="http://www.leman21.ch/" target="_blank">Léman21</a>, j'ai apprécié ton
enthousiasme et tes idées pour les écoles doctorales. Ce projet, de mon
point de vue, fùt un réel succès, et j'espère que tu en garderas un bon
souvenir.</div>
<div>
<br /></div>
<div>
Ta vie est maintenant à un nouveau
tournant. Je te souhaite vraiment de pouvoir réinventer un nouveau
chemin, hors des murs parfois un peu fermés de l'Université. Nouveau
chemin qui passera par les questions d'environnement et de développement
durable si je ne me trompe pas.</div>

c’est un Homme au grand Cœur. Il sait choisir ses amis et est
fidèle en amitié. Comme Doctorant, je lui ai conté l’histoire
des sols ferrallitiques du Sud<span style="background: transparent;">
Cameroun et il s’y est plu. Les revues scientifiques « Compte
Rendu de Géosciences » et « Science of the Total
Environnement » ont publié ces premières idées. Hans Ruedi
m’a ouvert toutes ses portes, au bureau à l’Unil, à l’avenue
Glayre, au Tessin comme à Winterthur. Il m’a conduit au DESNE à
Genève, m’a confié une partie de ses études à Camignolo au
Tessin sur la contamination des eaux par l’arsenic. Nous les avons
publiées dans Geoderma. </span></div>

Dear friends, I would like to thank all those who personally attended my good-bye lecture on Nov. 1 and all those who have sent me mails to tell that they could not attend. It was a very emotional moment, but I had the feeling that the message I wanted to transmit got through!

Seydou nous y raconte que la collaboration avec Lausanne est un grand succès non seulement parce que le professeur était très compétent, mais aussi grâce a son grand ouverture d'esprit.

<br />
Septembre 1990</div>
<div class="western" style="margin-bottom: 0.14in;">
Ma candidature à un
poste de professeur à l'Institut de Minéralogie et Pétrographie a
été retenue. Je suis invité à visiter l'institut et faire une
leçon. Nous descendons avec Albrecht Steck, le directeur en titre de
l'Institut, au Centre d'Analyse Minérale au niveau 1 de ce qui était
encore le BFSH2 pour rencontrer le professeur responsable de ce
centre Hans Ruedi Pfeifer.</div>
<div class="western" style="margin-bottom: 0.14in;">
Le Centre m'apparaît
comme une petite fourmilière avec des travaillant étudiants dans
des labos exigus mais bourrés de matériel. J'apprends alors qu'ici
chaque étudiant est formé pour préparer son matériel analysé en
Fluorescence X. Inimaginable dans mon laboratoire parisien d'origine
!</div>
<div class="western" style="margin-bottom: 0.14in;">
Albrecht frappe à
la porte d'un bureau dont la seule indication est une caricature d'un
monsieur avec un immense sourire accueillant. La porte passée le
professeur Pfeifer m'accueille avec ce grand sourire qui le
caractérise. Son bureau est aux antipodes de ce que je conçois, des
bouquins en colonnes, des piles d'articles dont on se demande comment
elles tiennent. Nous arrivons à dégager une petite place sur une
table pour discuter. Et d'emblée je découvre la convivialité et
l'esprit de groupe d'Hans-Ruedi. Le courant passe aussitôt et je
sens que si je suis retenu j'aurai là une collaboration possible
avec quelqu'un d'efficace. La visite de son laboratoire me confirme
qu'il y a là un laboratoire de qualité, géré par un chercheur
comme je l'ai toujours imaginé.</div>
<div class="western" style="margin-bottom: 0.14in;">
Engagé à Lausanne,
professeur puis directeur de l'institut puis doyen d'une nouvelle
faculté j'ai gardé la même qualité de contact avec Hans-Ruedi.
</div>
<div class="western" style="margin-bottom: 0.14in;">
Septembre 2003</div>
<div class="western" style="margin-bottom: 0.14in;">
Ouverture de la
Faculté des Géosciences et Environnement. Je me trompe peut être
mais j'ai eu l'impression lorsque nous nous somme tournés vers
l'environnement que nous ouvrions une porte qu'il attendait depuis
longtemps. J'en veux pour preuve son engagement immédiat, tant en
enseignement qu'en recherche, et il est certainement l'un de ceux qui
a le plus travaillé pour consolider cette orientation fondamentale
de la faculté. Il est vrai qu'il nous avait précédé dans ce
domaine en travaillant sur des problèmes de remédiation et autres
pollutions minières.</div>
<div class="western" style="margin-bottom: 0.14in;">
Hans Ruedi s'est
engagé totalement dans cette aventure et je lui en suis infiniment
reconnaissant car il est de ceux qui ont permis que cette expérience
réussisse. Pour l'avoir vécue de près, je sais que c'était loin
d'être acquis et c'est grâce à des scientifiques comme lui avec
leur diversifier nos programmes d'enseignement et construire ce bel
instrument de recherche qui vient de fêter se 10 ans en 2013.</div>
<div class="western" style="margin-bottom: 0.14in;">
Septembre 2013</div>
<div class="western" style="margin-bottom: 0.14in;">
Il paraît que tu
nous quittes, pas vraiment car je suis sûr que ce blog sera un lien
très fort avec tes amis de la faculté, tes étudiants et va te
permettre de poursuivre une forme d'enseignement. J'espère
contribuer en y laissant mes commentaires à tes articles. Gardes
toujours ton légendaire sourire en écrivant tes chroniques et à
très bientôt…</div>

<br />
From my childhood perspective, my father has always been a person who would run into the mountains and collect a whole bunch of stones. I never really understood why one could be so exited about something as dead and cold as a stone. Maybe that's the reason why I moved to social sciences and studied economics.<br />
For a long time in my life I successfully managed to ignore my father's professional world. I was the economist, he was the geologist. But one day this has changed. I had the strong feeling that economics was not giving me the answers which i was looking for, so I decided to join in an interdiscipinary seminar on environmental issues. Before I knew it, i was sitting in an auditorium listening to my own father.<br />
<br />
I suddendly discovered a man, who beyond the inexplicable enthousiam for stones, is a very broadly interested person. Whatever the emerging topic is, he always manages to collect an incredible number of publications and become an expert on the topic within no time. He always has pretty avant-gardistic ideas and opinions about environmental issues, inspiring many others to do reseach in his direction.<br />

</tbody></table>
I guess this was an important turn over in our father-daughter relationship. We suddendly discovered that we have very different views on the world, but bringing them together would cross-fertilize our thoughts and our work.<br />
<br />
An initial step in this cross-fertilisation was the creation of the environmental systems bachelor class at the newly created faculty for geosciences and environment at the university of Lausanne, to which i could contribute with my pedagocial flair and learn more about environmental sciences. I ended up, writing a PhD on the edge of economics and geosciences and became a GIS specialist.<br />
<br />
Thanks to some PhD students, Africa became one my father's new challenge. I remember reading through one of his research proposal. It was focusing on water analysis. As an economist, I found that very irrelevant and ended up rewriting the introduction focusing on the challenge of eradicating poverty in Africa and how reuse of used water could contribute to this goal (obviously by making some water analysis). This project proposal was accepted (probably more because the project was good rather than my introduction) and was the start of my father's big Senegal adventure.<br />
<br />
Probably inspired by my father's work, I joint Nile Basin Challenge Program in Ethiopia for my post doc, where I learnt a lot not only about matching agricultural technolgies to the context of the rural communities, but also about social medias and how to reach out to people, sharing scientific knowledge with non-scientists. My <a href="http://catherinepfeifer.blogspot.com/" target="_blank">blog</a> focusing on developments in rural areas, has become a space of debate, a source of information and reportings from the realities on the ground that with more than 1000 clicks per months is regularly followed by a small but interested community. It has proven to me, that new media offers us new spaces to share, to integrate and to interact. <br />

</tbody></table>
Over his lifetime, my father has been inspiring many students and colleagues, but with this retirement, he will loose the university plateform and its enthousiatic students. However it does not mean that he has nothing to share anymore nor that he cannot inspire up-coming generations with his avant-gardistic thoughts. For this reason, I am launching today his personal blog, his new space to share and interact with you, making sure that his retirement is a new begining in which you former students, colleages and friends can continue interacting and maybe meet new people to interact with.<br />
<br />
I am just left with wishing my father many inspiring interactions for the up-coming years and a good start into the virtual world of social media. Catherinehttp://www.blogger.com/profile/17604619141000944825noreply@blogger.com0
