Every day\u00a0action. Intentional choices. Impact that lasts.\u00a0<\/span><\/i>\u00a0<\/span><\/p>\n

On Earth Day, it\u2019s easy to focus on big promises and bold commitments. But during our recent fireside chat with <\/span>Casa en el Agua<\/span><\/a>, a simple but powerful message emerged: sustainability is built through intention, consistency, and everyday action.<\/span>\u00a0<\/span><\/p>\n

Casa en el Agua is a hostel quite literally built in the middle of the Caribbean Sea. And what resonated most wasn\u2019t just the innovation – from solar power, and desalinated water, to dry toilets, and mangrove restoration – but <\/span>how<\/span><\/i>\u00a0those decisions\u00a0were made.<\/span>\u00a0<\/span><\/p>\n

Sustainability at Casa en el Agua didn\u2019t start with a plan or long-term strategy. It started with a bold idea and a willingness to listen to the local community, to the environment, and to what was realistically possible.\u00a0 <\/span>\u00a0<\/span><\/p>\n

As co-founder Ronald Hurtado put it best:\u00a0<\/span>\u201cSustainability doesn\u2019t need to be perfect;\u00a0it just needs to be intentional.\u201d\u00a0And whether at home or while travelling, small,\u00a0conscious choices\u00a0really do\u00a0add up.\u00a0<\/span>\u00a0<\/span><\/p>\n

\u00a0<\/span>A\u00a0Hostel\u00a0Built on\u00a0Listening<\/span><\/b>\u00a0<\/span><\/h2>\n

\"\"<\/p>\n

Located approximately two hours by boat from Cartagena, Casa en el Agua sits within Colombia\u2019s San Bernardo Islands archipelago. Before it became a hostel, it was simply a house floating above the sea. When co- founder Ronald Hurtado and his partners first discovered it, sustainability wasn\u2019t the goal, survival was.<\/span>\u00a0<\/span><\/p>\n

\u201cWe didn\u2019t know how to live in the middle of the ocean,\u201d\u00a0Ronald\u00a0shared.\u00a0\u201cThe local community did. So\u00a0that\u2019s\u00a0where we started,\u00a0by listening.\u201d<\/span>\u00a0<\/span><\/p>\n

The\u00a0local\u00a0community, primarily based on\u00a0Islote\u00a0Santa Cruz,\u00a0have\u00a0lived from the sea for\u00a0hundreds of\u00a0years. Building trust and learning from them shaped every decision that followed,\u00a0from sourcing food and managing waste to energy, water, and employment.<\/span>\u00a0<\/span><\/p>\n

Sustainability at Casa\u00a0en\u00a0el\u00a0Agua\u00a0wasn\u2019t\u00a0imposed;\u00a0it was learned\u00a0from those who had been there before.\u00a0<\/span>\u00a0<\/span><\/p>\n

Redefining \u2018Normal\u2019\u00a0Operations<\/span><\/b>\u00a0<\/span><\/h2>\n

Living above the sea leaves little room for shortcuts\u00a0or traditional hostel operations. Early on, the team\u00a0realised\u00a0that what works on land simply\u00a0wouldn\u2019t\u00a0work here.\u00a0<\/span>\u00a0<\/span><\/p>\n

Challenges included:\u00a0<\/span>\u00a0<\/span><\/p>\n

    \n
  • Flush toilets sending waste directly into the ocean\u00a0<\/span>\u00a0<\/span><\/li>\n<\/ul>\n
      \n
    • Diesel generators creating constant noise and pollution\u00a0<\/span>\u00a0<\/span><\/li>\n<\/ul>\n
        \n
      • Fresh water being bought and carefully rationed using buckets<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

        Practical solutions included:\u00a0<\/span>\u00a0<\/span><\/p>\n

          \n
        • Dry toilets (inspired by systems on Colombia\u2019s Pacific Coast) kept waste out of the sea.\u00a0<\/span>\u00a0<\/span><\/li>\n<\/ul>\n
            \n
          • Diesel generators were replaced with solar power, allowing the hostel to run quietly and cleanly.\u00a0<\/span>\u00a0<\/span><\/li>\n<\/ul>\n
              \n
            • Later, a desalination system was added to convert seawater into drinkable water,\u00a0not only for guests, but also for staff and their families.<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

              The\u00a0trade<\/span>\u2011off, while\u00a0unfamiliar or even uncomfortable,\u00a0was\u00a0clear: protect the ecosystem they call home,\u00a0or risk losing it altogether.<\/span>\u00a0<\/span><\/p>\n

              Protecting\u00a0What\u2019s\u00a0Disappearing<\/span><\/b>\u00a0<\/span><\/h2>\n

              One of the most powerful moments of the fireside chat came when\u00a0Ronald\u00a0spoke about nearby islands that have already disappeared due to erosion and climate change,\u00a0most notably affecting the tides.\u00a0<\/span>\u00a0<\/span><\/p>\n

              What was once an archipelago of over a dozen small islands has shrunk dramatically.\u00a0Mangroves that once\u00a0stabilised\u00a0land have vanished, and migratory birds have fewer safe places to rest.<\/span>\u00a0<\/span><\/p>\n

              In response, Casa\u00a0en\u00a0el\u00a0Agua began\u00a0a\u00a0mangrove<\/span>\u2011planting\u00a0initiative\u00a0on\u00a0the\u00a0nearby island\u00a0of\u00a0<\/span>Mangle<\/span><\/i>, working alongside local communities, guests, and partners.\u00a0<\/span>\u00a0<\/span><\/p>\n

              Progress is slow\u00a0and\u00a0intentional.\u00a0\u201cThis isn\u2019t something we\u2019ll fix in a weekend,\u201d\u00a0Ronald\u00a0said.\u00a0\u201cBut if we don\u2019t start, the island won\u2019t exist.\u201d<\/span>\u00a0<\/span><\/p>\n

              Guests\u00a0as Conscious Participants\u00a0<\/span><\/b>\u00a0<\/span><\/h2>\n

              \"\"<\/span><\/p>\n

              Casa\u00a0en\u00a0el\u00a0Agua\u00a0doesn\u2019t\u00a0expect guests to be sustainability experts, or to sacrifice enjoyment.\u00a0Guests are there to relax, disconnect, and experience something special.\u00a0<\/span>\u00a0<\/span><\/p>\n

              What is expected is awareness.\u00a0<\/span>\u00a0<\/span><\/p>\n

              Each stay begins with an explanation of why things work differently, scheduled shower times, waste separation, and strict care around the surrounding environment.\u00a0It\u2019s\u00a0not about\u00a0rules,\u00a0it\u2019s\u00a0about respect.\u00a0<\/span>\u00a0<\/span><\/p>\n

              Many guests take these lessons home, using less water and being more mindful of their impact. Others resist at first, only to change their perspective later.\u00a0<\/span>\u00a0<\/span><\/p>\n

              \u201cWe\u2019re all guests here,\u201d\u00a0Ronald\u00a0reminded us.\u00a0\u201cNot just at the hostel,\u00a0on the planet.\u201d<\/span>\u00a0<\/span><\/p>\n

              The\u00a0BIGGEST\u00a0Takeaway:\u00a0Start\u00a0Small,\u00a0Start\u00a0at\u00a0Home<\/span><\/b>\u00a0<\/span><\/h2>\n

              When asked what small, realistic change anyone could make beyond Earth Day,\u00a0Ronald\u2019s answer was simple:\u00a0Start at home.<\/span>\u00a0<\/span><\/p>\n

              Take shorter showers, wash\u00a0your\u00a0clothes less often,\u00a0turn off running taps, walk whenever\u00a0possible, and do what you can to recycle properly,\u00a0even when\u00a0it\u2019s\u00a0inconvenient. Then\u00a0take\u00a0that same mindset\u00a0with\u00a0you when\u00a0you\u00a0travel.\u00a0<\/span>\u00a0<\/span><\/p>\n

              Sustainability\u00a0doesn\u2019t\u00a0put a\u00a0pause on\u00a0your holiday, if anything, travel often magnifies impact.\u00a0Which makes\u00a0conscious\u00a0choices\u00a0matter even more.<\/span>\u00a0<\/span><\/p>\n

              \u201cYour sustainability doesn\u2019t need to be perfect,\u201d\u00a0Ronald\u00a0said.\u00a0\u201cIt just needs to be intentional.\u201d<\/span>\u00a0<\/span><\/p>\n

              A\u00a0Reminder\u00a0Worth\u00a0Carrying\u00a0Forward<\/span><\/b>\u00a0<\/span><\/h2>\n

              Casa\u00a0en\u00a0el\u00a0Agua shows what\u2019s possible when sustainability, creativity, and community come together. Not as a campaign or marketing message, but as a way of living and\u00a0operating.<\/span>\u00a0<\/span><\/p>\n

              As we reflect on Earth Day, their story offers something grounding:<\/span>
              \nMeaningful impact\u00a0doesn\u2019t\u00a0start\u00a0with notions of grandeur. It starts with everyday decisions,\u00a0made thoughtfully, consistently, and with care for the people and places around us.<\/span>\u00a0<\/span><\/p>\n

              Every day can be Earth Day\u00a0if we\u00a0want\u00a0it to be.\u00a0<\/strong>\ud83c\udf31<\/p>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":204,"featured_media":1275681,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"hw_hurry":"","hw_related":"[{\"id\":317147,\"score\":0.79969999999999996642685573533526621758937835693359375,\"hook\":\"\"},{\"id\":1270416,\"score\":0.689200000000000034816594052244909107685089111328125,\"hook\":\"\"},{\"id\":1294377,\"score\":0.65590000000000003854694341498543508350849151611328125,\"hook\":\"\"},{\"id\":1275296,\"score\":0.64139999999999997015720509807579219341278076171875,\"hook\":\"\"},{\"id\":1275959,\"score\":0.61009999999999997566391130021656863391399383544921875,\"hook\":\"\"},{\"id\":1266738,\"score\":0.58940000000000003499422973618493415415287017822265625,\"hook\":\"\"}]","footnotes":""},"categories":[10211],"tags":[264341],"class_list":["post-1275676","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-sustainability","tag-sustainability","authors-stephanie-stewart","wpbf-post"],"yoast_head":"\nSustainability Stories: Earth Day -
