  • Top 3 challenges for livestock emission calculators

    Top 3 challenges for livestock emission calculators

    Seaspray Labs is currently designing and developing livestock emission calculators. But let’s step back. Why do we need to quantify livestock emissions? Most countries have agreed to reduce greenhouse gas emissions. Now we need reliable ways to measure and track emissions to see where we stand. There are several greenhouse gasses that are emitted from livestock farming. For example ruminants, such as cattle, emit methane, a potent greenhouse gas. The good news? There are many things we can do to reduce emissions, from eating a more plant-rich diet to feed adjustments for cattle. How can we quantify and measure current emissions and future reductions? We are designing a calculator for livestock emissions and here are our top three challenges.

    Challenge 1: Different experience levels. Who are our end users? We have expert users, who know all the details of climate science for livestock. One the other side we have absolute beginners, who have been tasked with creating an inventory for livestock emissions without having prior experience in this field. How can we explain and simplify this extremely complex process and at the same time allow experts to quickly enter data and navigate results?

    Challenge 2: Limited data. Inventory compilers enter or import activity data to then estimate emissions. For livestock this means data such as how many animals, at what temperature are animals being kept, and what manure management systems are being used. Some users have extremely limited data sets. How can we allow these users to plug in the data they have and generate comparable emission estimations with the help of default values?

    Challenge 3: Complex datasets. On the other hand, there are inventory compilers with extremely complex datasets. Their livestock species are divided into populations and subcategories. For each subcategory they have different temperature and manure management system usage data. While this is great for reducing uncertainty, it poses other challenges. How can we provide estimations that are transparent and easy to manipulate?

    Design thinking is about solving problems and tackling challenges. Let’s hope we can solve these challenges and address the different user needs. Our goal is to make emission estimation easier, more user friendly, and more transparent. Seaspray Labs works to quantify emissions and hopefully bring us closer to a low carbon future.

  • How Drones Help Tackle Climate Change

    How Drones Help Tackle Climate Change

    A while ago I wrote about an amazing project that uses drones to re-grow mangrove trees in Myanmar. The world urgently needs a range of solutions to offset carbon emissions, and trees play a major role. How do trees tackle climate change? Trees capture carbon dioxide from the air and store it in biomass, roots and soil. According to the Trillion Tree Campaign, global reforestation binds at least a quarter of the annual man-made carbon dioxide emissions.

    I love the mangrove project in Myanmar! At the same time I have been reading about our yearly tree losses in North America and Europe. That made me wonder: What are we doing to replant trees closer to home? That’s where the Canadian startup Flash Forest comes into play.

    Imagine you are walking through a big, green, majestic forest, breathing in the cool, fresh air. Can you hear the sounds of birds and other forest animals? This week’s climate story brings us to a forest in Canada. Actually, for now, it’s land that recently burnt down in a wildfire. With Flash Forest’s help, hopefully, it will be a forest soon. Flash Forest is a reforestation company that uses drones to reforest areas. This is how it works:

    First, the land is mapped to identify where and how to grow a mix of native trees. Then drones drop seed pods in the soil. After planting, the drones monitor the progress and replant spots if necessary.

    The seed pods are also designed to store moisture, so the seedlings can survive even with months of drought

    What I like most about Flash Forest is their focus on offsetting carbon emissions. Their motto is if we automate deforestation, we should automate re-forestation as well.

    All over the world, small startups such as Flash Forest are addressing different solutions to tackle climate change. I hope that adding up all these small projects will make a big difference!

  • Can Kelp Forests Stop Global Warming?

    Can Kelp Forests Stop Global Warming?

    Imagine diving through an underwater area with a lot of giant algae, a kelp forest. These underwater forests are very productive ecosystems and capture carbon the same way as forests on land. They take in carbon dioxide, produce oxygen, and create a healthy ecosystem for plants and animals. Unfortunately, these kelp forests are in danger. As the planet is getting warmer much of that heat is absorbed by warmer surface waters in the ocean. That warm water layer is getting bigger and nutrients from cold currents can’t reach the kelp forests any more. Kelp and marine animals are disappearing and ocean deserts are getting bigger. That sounds terrifying, is there a way to stop that trend? Actually, there is.

    Growing back kelp forests may be one of the most extraordinary ways to reverse global warming

    https://www.drawdown.org/solutions/coming-attractions/marine-permaculture

    Today’s post is about Dr. Brian Von Herzen and his climate foundation. He came up with a way of restoring cold ocean currents to reestablish plankton, kelp, and fish. His invention is a wave powered tube that pumps cold water to an underwater structure to regrow plankton and kelp. This is how it works.

    The left picture shows how cold currents naturally work. As wind blows warmer water to the side it gets replaced by cold, nutrient rich water. The nutrients help plankton, kelp, and seagrass to grow and marine animals to flourish. The picture in the middle shows how the warm water layer expands with raising temperatures. Cold, nutrient rich water can’t reach the kelp forest and ocean deserts expand.

    The picture on the right shows Brian’s cold water pump. It pumps cold, nutrient rich water from deeper levels closer to the surface. The water flows into a structure where plankton and kelp can grow and bring back other marine plants and animals.

    Restoring plankton and kelp sounds like a great idea. The numbers for carbon sequestration are actually massive and could make a real impact! Plankton are tiny but significant.

    “They comprise half of the organic matter on earth and produce at least half of the earth oxygen”

    http://www.climatefoundation.org/what-is-marine-permaculture.html

    As with plankton, kelp sequesters huge amounts of carbon dioxide. On top of that, kelp can be harvested and utilized:

    Floating kelp forests could provide food, feed, fertilizer, fiber, and biofuels to most of the world

    I love this brilliant invention! Climate Foundation is currently testing the pump in Australia and the Philippines. Hopefully this can be adapted more widely soon so that we can restore ocean health, capture carbon emissions, and maybe one day reverse global warming!

  • Can we Turn Greenhouse Gases into Water Bottles?

    Can we Turn Greenhouse Gases into Water Bottles?

    As user experience designers we create customer journeys. In those journeys or scenarios we design how a customer might use our product. Imagine we wanted to design a smartwatch. We don’t just think about the moment someone interacts with the watch but sketch out an entire day. This helps us make better design decisions.

    That got me thinking… What is the customer journey of a plastic bottle? We drink the water, but what happens before and after? What is the entire lifecycle of a water bottle? This is what I sketched up…

    Lifecycle of a water bottle from production to

    Nearly all bottles are made from petroleum. During the oil extraction and the manufacturing of plastic, greenhouse gasses are released into the air. Then during transportation more greenhouse gases are released. After we enjoy the water and throw it away, I sketched five different endings:

    • A. Recycle into other plastics for carpets or tiles (only 7 % of plastic in the US is recycled)
    • B. Greenhouse gases and toxins are released when burning plastic
    • C. It takes hundreds of years to decompose and toxins each into soil and groundwater when put in the landfill
    • D. In the ocean it kills and negatively affects marine life and ends up in our food chain
    • E. When decomposing into microplastics it kills or harms bacteria that convert carbon dioxide into oxygen

    I promised you positive and inspiring stories and so far this post has been pretty depressing. In a recent post I featured water pouches made from algae.

    Here is another fantastic startup, this time from California.  Cove makes water bottles out of polyhydroxyalkanoate (PHA) – wow, that’s a long word. It’s biodegradable, compostable and produces zero toxic waste.

    It is produced by microorganisms feeding on sugar, starches or greenhouse gases. I love this part: Microorganisms can actually turn greenhouse gases, such as waste methane and carbon dioxide, into biodegradable PHA plastics. Companies like Newlight Technologies are developing these kind of bioplastics.

    Imagine a plastic-like material that is produced by greenhouse gas eating bacteria! Cove is currently testing how long it will take to break down the bottles in different scenarios. They are launching in California this year, so stay tuned!
