The unique characteristics of Polynesian territories highlight the difficulties faced by their inhabitants: the dispersion of islands and atolls can quickly turn tranquility into isolation, and their supply chains are heavily dependent on the state of the sea and weather conditions, as well as on a strong reliance on imported fossil fuels for energy.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"862\" height=\"900\" data-attachment-id=\"8280\" data-permalink=\"https:\/\/recherche.upf.pf\/en\/laboratoire\/gepasud\/attachment\/image-23\/\" data-orig-file=\"https:\/\/recherche.upf.pf\/wp-content\/uploads\/2024\/02\/image-23.png\" data-orig-size=\"872,910\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"image-23\" data-image-description=\"\" data-image-caption=\"\" data-medium-file=\"https:\/\/recherche.upf.pf\/wp-content\/uploads\/2024\/02\/image-23-300x300.png\" data-large-file=\"https:\/\/recherche.upf.pf\/wp-content\/uploads\/2024\/02\/image-23-862x900.png\" src=\"https:\/\/recherche.upf.pf\/wp-content\/uploads\/2024\/02\/image-23-862x900.png\" alt=\"Energie PF\" class=\"wp-image-8280\" style=\"width:259px;height:auto\" srcset=\"https:\/\/recherche.upf.pf\/wp-content\/uploads\/2024\/02\/image-23-862x900.png 862w, https:\/\/recherche.upf.pf\/wp-content\/uploads\/2024\/02\/image-23-287x300.png 287w, https:\/\/recherche.upf.pf\/wp-content\/uploads\/2024\/02\/image-23-57x60.png 57w, https:\/\/recherche.upf.pf\/wp-content\/uploads\/2024\/02\/image-23-600x626.png 600w, https:\/\/recherche.upf.pf\/wp-content\/uploads\/2024\/02\/image-23.png 872w\" sizes=\"auto, (max-width: 862px) 100vw, 862px\" \/><figcaption class=\"wp-element-caption\"><strong>French Polynesia is highly vulnerable due to its dependence on fossil fuels.<\/strong><\/figcaption><\/figure>\n<\/div>\n\n\n<p>Weather phenomena can be so intense in this region that French Polynesia holds the world record for rainfall, with populations regularly exposed to devastating floods and marine inundations.<\/p>\n\n\n<div class=\"wp-block-image is-resized\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"900\" height=\"328\" data-attachment-id=\"4856\" data-permalink=\"https:\/\/recherche.upf.pf\/en\/laboratoire\/gepasud\/attachment\/intemperiestahiti\/\" data-orig-file=\"https:\/\/recherche.upf.pf\/wp-content\/uploads\/2022\/09\/intemperiesTahiti.png\" data-orig-size=\"1146,418\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"intemperiesTahiti\" data-image-description=\"\" data-image-caption=\"\" data-medium-file=\"https:\/\/recherche.upf.pf\/wp-content\/uploads\/2022\/09\/intemperiesTahiti-300x300.png\" data-large-file=\"https:\/\/recherche.upf.pf\/wp-content\/uploads\/2022\/09\/intemperiesTahiti-900x328.png\" src=\"https:\/\/recherche.upf.pf\/wp-content\/uploads\/2022\/09\/intemperiesTahiti-900x328.png\" alt=\"4\" class=\"wp-image-4856\" srcset=\"https:\/\/recherche.upf.pf\/wp-content\/uploads\/2022\/09\/intemperiesTahiti-900x328.png 900w, https:\/\/recherche.upf.pf\/wp-content\/uploads\/2022\/09\/intemperiesTahiti-300x109.png 300w, https:\/\/recherche.upf.pf\/wp-content\/uploads\/2022\/09\/intemperiesTahiti-60x22.png 60w, https:\/\/recherche.upf.pf\/wp-content\/uploads\/2022\/09\/intemperiesTahiti-600x219.png 600w, https:\/\/recherche.upf.pf\/wp-content\/uploads\/2022\/09\/intemperiesTahiti.png 1146w\" sizes=\"auto, (max-width: 900px) 100vw, 900px\" \/><figcaption class=\"wp-element-caption\"><strong>Illustration of the recurrence of major weather events in French Polynesia (Tahiti) as depicted in the press.(2015<strong>[2]<\/strong>;2015<strong>[3]<\/strong>;2016<strong>[4]<\/strong>;2017<strong>[5]<\/strong>; 2017<strong>[6]<\/strong>;2017<strong>[7]<\/strong>;2022<strong>[8]<\/strong>).<\/strong><\/figcaption><\/figure>\n<\/div>\n\n\n<p>One of the main sources of income for French Polynesia is tourism, drawn by the stunning landscapes, lush vegetation, and the richness of its lagoons and ocean.

For instance, to better manage freshwater resources and predict floods, there is a need to improve small-scale and short-term weather predictions. This, in turn, requires the ability to anticipate the availability of solar, wind, and hydroelectric energy. Consequently, energy production systems and networks must be adapted accordingly. Furthermore, improving weather forecasts involves gaining a better understanding of the sea, atmosphere, land, and their vegetation cover. Therefore, these Polynesian issues cannot be addressed in isolation; they represent a complex network of interconnected scientific challenges.<\/p>\n\n\n\n<p>To overcome this complex network of challenges, it is essential to approach it as a whole rather than as a collection of isolated problems. Global models need to be developed that benefit from improvements in all the involved domains: large- and small-scale models of vegetation, marine environments, weather, hydrology, and geography. These models should be leveraged to create sustainable long-term ecological alternatives for energy and refrigeration. To make these models viable, a sufficient amount of data is needed, collected from a variety of sensors. However, existing solutions are prohibitively expensive, and their telephonic or satellite operations are beyond reach.<\/p>\n\n\n\n<p>New networks and sensors, based on emerging low-cost, low-power, low-import-cost, and low-carbon-impact technologies\u2014referred to as &#8220;low-4&#8243;\u2014must be designed to enable continuous, low-cost, and environmentally friendly monitoring.<\/p>\n\n\n\n<p>A new paradigm of scientific synergies must be employed, and GEPASUD is one of the solutions to addressing this complex network of challenges.&nbsp;<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"900\" height=\"429\" data-attachment-id=\"8219\" data-permalink=\"https:\/\/recherche.upf.pf\/en\/laboratoire\/gepasud\/attachment\/image-14\/\" data-orig-file=\"https:\/\/recherche.upf.pf\/wp-content\/uploads\/2024\/02\/image-14.png\" data-orig-size=\"1977,942\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"image-14\" data-image-description=\"\" data-image-caption=\"\" data-medium-file=\"https:\/\/recherche.upf.pf\/wp-content\/uploads\/2024\/02\/image-14-300x300.png\" data-large-file=\"https:\/\/recherche.upf.pf\/wp-content\/uploads\/2024\/02\/image-14-900x429.png\" src=\"https:\/\/recherche.upf.pf\/wp-content\/uploads\/2024\/02\/image-14-900x429.png\" alt=\"Societal challenge and the GEPASUD\" class=\"wp-image-8219\" style=\"width:501px;height:auto\" srcset=\"https:\/\/recherche.upf.pf\/wp-content\/uploads\/2024\/02\/image-14-900x429.png 900w, https:\/\/recherche.upf.pf\/wp-content\/uploads\/2024\/02\/image-14-1600x762.png 1600w, https:\/\/recherche.upf.pf\/wp-content\/uploads\/2024\/02\/image-14-300x143.png 300w, https:\/\/recherche.upf.pf\/wp-content\/uploads\/2024\/02\/image-14-60x29.png 60w, https:\/\/recherche.upf.pf\/wp-content\/uploads\/2024\/02\/image-14-600x286.png 600w, https:\/\/recherche.upf.pf\/wp-content\/uploads\/2024\/02\/image-14.png 1977w\" sizes=\"auto, (max-width: 900px) 100vw, 900px\" \/><figcaption class=\"wp-element-caption\"><strong>Cross-Cutting Actions of GEPASUD<\/strong><\/figcaption><\/figure>\n<\/div>\n\n\n<p>Organized into three thematic teams, the GEPASUD laboratory brings together and converges the necessary expertise for research and development aimed at providing coordinated, viable, and economically advantageous solutions to help French Polynesia manage its territory.
