MapBiomas Water Platform Amazon Countries launched on Wednesday (20)<\/em><\/strong><\/p>\n\n\n\n

The launch of the MapBiomas Water Platform<\/a> for the Amazon Countries took place on Wednesday, September 20 of this year. <\/p>\n\n\n\n

The historical average water surface in this vast region for the period between 2000 and 2022 is 25.4 million hectares (Mha). But in the last decade, all the Amazon countries have seen a reduction in surface water. When comparing the average of the last decade with the historical average for the period, 1 million hectares of water surface were lost in the nine Amazonian countries. This is despite the gain of 747,000 ha (compared to the historical average) recorded in 2022, which brought the total water surface area to 26.2 Mha, representing 2% of the territory analyzed.<\/p>\n\n\n\n

Brazil was largely responsible for this gain in 2022: 910,000 ha more water surface were identified last year compared to the historical average of 17.9 Mha of water surface. The 18.8 Mha recorded in 2022 in Brazil represent 72% of the total water surface of the Amazon countries.<\/p>\n\n\n\n

The gain in water surface area in Brazil in 2022 is more than four times the total water surface area in Ecuador last year (227,000 ha). On the other hand, Peru lost the most water surface in this period: 124,000 ha, a relative loss of 7% compared to its historical average (1.8 Mha).<\/p>\n\n\n\n

In general, however, the nine Amazonian countries have undergone a series of critical transformations in their water resources over the last two decades that have resulted in a general trend of shrinking water surface area. For Bolivia, Brazil, Colombia, Ecuador, Guyana, French Guiana, Peru, Suriname and Venezuela, the interval between 2013 and 2021 was identified as the period with the lowest water surface in the historical series analyzed.<\/p>\n\n\n\n

“En nuestra regi\u00f3n, hay tres pa\u00edses que han mostrado una reducci\u00f3n en su superficie de agua durante todo el per\u00edodo entre 2000 y 2022: Ecuador, Per\u00fa y Bolivia. Los otros seis pa\u00edses mostraron un per\u00edodo de aumento y otro de disminuci\u00f3n en el \u00e1rea de superficie de agua en relaci\u00f3n con el promedio hist\u00f3rico, que ocurri\u00f3 entre 2013 y 2021, con tendencias similares, pero de magnitudes variables”, comenta Eva Mollinedo, de la Fundaci\u00f3n Amigos de la Naturaleza (FAN-Bolivia) y miembro del equipo de MapBiomas Agua Pa\u00edses Amaz\u00f3nicos.<\/p>\n\n\n\n

The reduction in the water surface is also evident in a sustained trend of glacial melting which, between 1985 and 2022, led to the loss of an area of 184,000 hectares of glaciers, which is equivalent to 56% of the area detected in 1985. All Andean countries suffered glacier loss during this period. The greatest extent was in Peru, which lost 115,000 hectares; while Venezuela, the country with the least glacial coverage, suffered the greatest loss at 97% (82 hectares).<\/p>\n\n\n\n

“Esta disminuci\u00f3n podr\u00eda tener un impacto econ\u00f3mico en las poblaciones de los Andes tropicales, con efectos en la agricultura, el suministro de agua potable y la integridad de los ecosistemas”, seg\u00fan Juliano Schirmbeck de Geokarten (Brasil) y miembro del equipo de MapBiomas Agua Pa\u00edses Amaz\u00f3nicos. “Los glaciares tropicales han sufrido p\u00e9rdidas de \u00e1rea en respuesta al aumento de las temperaturas causadas por el acelerado cambio clim\u00e1tico global. Estos glaciares tropicales se consideran una especie de ‘term\u00f3metro’ para la Tierra, ya que su expansi\u00f3n o reducci\u00f3n est\u00e1 estrechamente relacionada con el clima global”, agrega.<\/p>\n\n\n\n

“Todo esto agrava los problemas de salud y las dificultades para acceder a alimentos, lo que es m\u00e1s perjudicial para las poblaciones con menos recursos econ\u00f3micos. Esta disminuci\u00f3n en la superficie de agua contribuye a la proliferaci\u00f3n de incendios forestales y emisiones de gases de efecto invernadero, lo que afecta tanto a la biodiversidad como a las comunidades locales”, comenta Carlos Souza Jr., de Imazon-Brazil y miembro del equipo de MapBiomas Agua Pa\u00edses Amaz\u00f3nicos.<\/p>\n\n\n\n
