Deslinde Lago de Tota - Etapa Probatoria (Inspección Ocular)
El día de hoy, se presentó por parte de la Agencia Nacional de Tierras (ANT), en el municipio de Tota, la explicación de esta fase en que se encuentra el proceso de deslinde del Lago de Tota: la etapa probatoria, mediante inspección ocular a todos los predios ribereños.
Los predios ribereños se han sectorizado (Sector 1: Tota; Sector 2: Cuítiva; y Sector 3: Aquitania). Durante los siguientes días (20 al 27 de agosto), la ANT dedicará un grupo profesional repartido en 5 cuadrillas, a la visita correspondiente a todos los predios ribereños del Sector 1.
Se comparte imagen de las diapositivas, presentación realizada por la ANT:
Se hizo registro de los audios durante la intervención, los hemos organizado en tres partes (p1: la presentación; p2: espacio de preguntas y respuestas; y p3: cronograma de visitas a realizar). Enlace a estos audios, accesible aquí.

Turbiedad y Estado Trófico | Lago de Tota (info UNEP)
 |
| Estado trófico, Lago de Tota (fuente: UNEP) Datos 2006-2010 y 2017-2019 (ver detalles adjuntos) |
Contexto (texto original):
Lake Water Turbidity and Trophic State Index:
The dataset measures two lake water parameters: Turbidity (TUR) and an estimate of Trophic State Index (TSI). For the two parameters the dataset documents monthly averages as well as multi-annual per-monthly averages for the periods 2006-2010 and 2017-2019. The products are mapped at a 300m spatial resolution capturing data for a total of 4265 lakes. Data is available per lake and each lake has individual identification information allowing it to be related to other hydrological datasets.
Source: The lake water turbidity and trophic state index data has been produced by the Copernicus Land Service.
Maps: Maps depicting mean deviations of turbidity and trophic state against individual lake baseline measurements are used.
Traducción
Índice de turbidez y estado trófico del agua del lago:
El conjunto de datos mide dos parámetros del agua del lago: turbidez (TUR) y una estimación del índice de estado trófico (TSI). Para los dos parámetros, el conjunto de datos documenta promedios mensuales, así como promedios mensuales plurianuales para los períodos 2006-2010 y 2017-2019. Los productos se mapean con una resolución espacial de 300 m y capturan datos de un total de 4265 lagos. Los datos están disponibles por lago y cada lago tiene información de identificación individual que permite relacionarlos con otros conjuntos de datos hidrológicos.
Fuente: Los datos del índice de estado trófico y turbidez del agua del lago han sido elaborados por el Copernicus Land Service.
Mapas: Se utilizan mapas que representan las desviaciones medias de la turbidez y el estado trófico frente a las mediciones de la línea de base de cada lago.

Richard A. Vollenweider, in memoriam
Universidade de Lisboa
Richard Albert Vollenweider died on January 20, 2007, at the age of 84. Born in Switzerland, he earned his Ph. D. at Zurich, spent some productive years of his scientific career at Pallanza, Italy, and eventually moved to Burlington, Canada, where soon became a senior scientist at the National Water Research Institute, Envi- ronment Canada.
Vollenweider deserves recognition from all of us for his pio- neer, fundamental research demonstrating that phosphorus was cru- cial in eutrophication of fresh water. Starting in 1966 by request of OECD, Vollenweider coordinated a group of scientists from all over the world working to find solutions to eutrophication; this resulted in the publication of the most significant of all technical reports ever produced (Vollenweider, 1968). For the first time a quantitative predictive model would relate the degree of eutrophi- cation to phosphorus loadings. In 1987 the Citation Classic no 35 stated that the Vollenweider report had already been cited in over 545 publications – quite unusual for a “gray” report. The OECD had to recopy the report several times to meet the demand, excee- ding 10,000 requests worldwide. Vollenweider himself said that his secretary had to send at least one or two copies a week per request. After the OECD report Vollenweider organized and coor- dinated an18 country Eutrophication Studies Program to collect data relating eutrophication to phosphorus loads in about 200 lakes of several continents – his findings were the underpinnings for the establishment of nutrient load limits in US and Canada. Vollenwei- der was the main advisor of the US and Canada joint governmental commission to solve the serious environmental problem involving Lake Erie and the other Great Lakes in the nineteen sixties – under his advice, the pollution of the world’s largest supply of fresh water was controlled and effectively re- versed. It is known that, after he managed to recover Lake Erie, Dr. Vollenweider won the nickname of “Dr. God”. The Vollenweider model was adopted thereafter in eutrophication control programs of many western countries. Vollenweider was also the vice-President of the ILEC, International Lake En- vironment Committee, and traveled everywhere in the world on assignments with UNESCO.
However, he has always kept a strong liaison to Italy: In 1978 he became the major advisor to the Italian Regional Government of Emilia-Romagna regarding eutrophication of the Adriatic Sea, working in a research center in Cesenatico, where he would go very often; he was co-President of the International Center for Advanced Environmental Studies Alessandro Volta in Como as well.
Richard A.Vollenweider was awarded, among others, the Tyler Environmental Prize (1986), con- sidered as the Nobel for environmental science, the Naumann-Thiennemann Medal by SIL (1987), the Global 500 Roll of Honor by UNEP (1988), the Premio Internationale Cervia for his advisory on eutrophication of the Adriatic Sea (Italy).
I first met Richard in Otsu, Japan, and I was astonished at his austerity. After that we met many other times, often at Pallanza where we used to have dinner together and take the lungolago for unending conversations, also at Portugal, for an incredible one-week tour four or five of us took after a meeting on phosphorus/eutrophication held at Lisboa. His friends Tommy and Yvette Edmondson first met Richard at Pallanza, where he was living and they visited in 1959/1960, and they told about the musical evenings with Vollenweider, including occasions when he played his violin (Edmondson & Edmondson, 1990). Richard faced life in a truly artistic attitude – he said about Tom Edmondson “we both shared enthusiasm for limnology but also the love for baroque music. Tommy and Yvette, more than anyone else I met, felt both that art is a necessary complement to science to enhance appreciation of both” (SILnews, Jan. 2001).
More than anything else, Richard loved to be among simple people: Stories such as that in the Nile traveling in a boat with Egyptian fishermen, all passing around the one glass of drink and telling stories of adventures in the river were told by him with true delight.
The passing of Richard A. Vollenweider is a great loss for science, yet, more than the eminent scientist, we lost the Man who persisted in his condition of being a true friend.

En estudio los últimos 30.000 años del Lago de Tota
 |
| Investigadores en el Lago de Tota, 2023 |
¿Cuánta información reposa en el depósito sedimentario del #LagodeTota?... varios siglos en datos 😳, por ahora se recopilan los últimos 30.000 años, en núcleos de sedimento para su estudio pormenorizado 👀
#paleolimnologia #ciencialagodetota
"Esta es la primera vez que en Suramérica se utilizan equipos de estos para hacer investigación. Por ahora, los investigadores involucrados tienen la seguridad de que en el lago de Tota seguirán trabajando por muchas más décadas."
