  • 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.

  • Can an API Make Rice Farming More Climate Friendly?

    Can an API Make Rice Farming More Climate Friendly?

    This story brings us to Vietnam where I presented at a webinar, organized by the IFC, the International Finance Corporation. Thankfully highly skilled translators were able to translate in realtime to and from Vietnamese to allow meaningful discussions across the globe. The topic was ”Digital Disruption in Agriculture Vietnam – GHG Emissions Measurement and Reporting Tools”. My talk covered a joint project from Seaspray Labs and Irri, the International Rice Research Institute.

    In other posts I already talked about the climate impact of rice and how different farming practices can drastically cut emissions. To cut emissions, we need to measure existing emissions and then make ongoing assessments to monitor and reduce emissions. IRRI’s scientists have developed highly accurate rice emission calculators over many years. These were originally Excel based and Seaspray Labs partnered with Irri to develop web-based versions of the calculators. Now we are going one step further and developing an API. It will allow partner organizations to access IRRI’s calculator in their own apps and services. This is how it works:

    This is how the API works for a fictional carbon credit app for rice farmers. The app gets rice farming information from its end user. These are the inputs the API needs to calculate emissions. The API then sends the results back to the app and the app can present these results meaningfully to its end user.

    This is one example I showed in my talk. A second example showed a very different app for a very different user group. I mocked up a regional planning app. Vietnam wants to reduce methane emissions by 30% by 2030 and moving to low-carbon rice production will play a major role. My mockup shows how a planner can adjust the percentage of low farming practices and traditional farming practices to explore emission reductions of entire regions by 2030.

    These are just two examples. The API is currently in development and I’m excited to see what other ideas IRRI’s partners will come up with. Hopefully these apps and services can translate into climate action for rice farmers, agriculture organizations, food companies, and consumers to reduce our carbon footprint.

  • How Can We Measure Climate Change Better?

    How Can We Measure Climate Change Better?

    Do you know how much money is in your bank account? How many calories does your white chocolate mocha have? How many steps did you walk today? We measure many aspects of our lives but when it comes to climate change our measurements are vague, and often nonexistent.

    This week’s climate story brings us to the beautiful rice paddies of Vietnam. Seaspray Labs partnered with the International Rice Research Institute. IRRI’s climate change team is based in Vietnam and they are working on carbon accounting tools for rice. Rice farming releases a lot of greenhouse gas emissions. Traditional techniques such as flooding rice paddies release the potent greenhouse gas methane. The good news? Changing farming practices can drastically reduce emissions while still producing the same amount of rice.

    We designed a web-based carbon calculator for rice growers, rice companies and scientists to better understand how different farming and processing methods for rice effect greenhouse gas emissions. We had three goals going into the project:

    • Easy access: Reach a bigger audience though a web-based tool
    • Intuitive experience: Provide a straightforward user experience
    • Understand data: Display data charts to measure, understand, and plan low emission practices

    While most team members were in Vietnam, we also interviewed partners and end users in the Philippines, Thailand, India, Germany, and the US. This was followed by rapid prototypes to learn how users might use the calculator. Through different iterations and continuous feedback, the tool improved quickly. After the final development and testing phase the calculator got successfully deployed. You can read more about our process here. In early tests with the recently released calculator we see the following results:

    • Easy access: Instead of installing a tool and having to cater to different operating systems the web tool successfully allows ad hoc access in lectures and webinars.
    • Intuitive experience: Streamlined pages guide users through the complex task of entering data for growing, processing, and transporting rice. It works well for novice users but also supports efficient expert data entry.
    • Understand data: Visual results allow users to view and compare the carbon footprint of different rice products. By comparing different farming and processing methods users can explore how to best reduce greenhouse gas emissions.

    We partnered with an amazing team of scientists and implemented the tool within weeks. Let’s hope it helps rice growers, rice companies and scientists to adopt low emission practices for rice. And let’s hope for more tools to measure the climate impact of the food we eat, the products we purchase, and the things we do.

  • An Unexpected Ingredient for Climate Action

    An Unexpected Ingredient for Climate Action

    This week’s climate story brings us all the way to the island Tasmania in Australia. Imagine standing next to a beautiful bay overlooking the Tasman Sea, this is where the company Sea Forest is headquartered.

    Have you heard that cows release the potent greenhouse gas methane? Have you also heard that mixing a little bit of seaweed in their diet reduces their emissions greatly? Research teams all over the world are racing to find out more: What type of seaweed works best? How much is needed? How can it be grown and mixed into feed sustainably?

    Asparagopsis is an edible red seaweed, native to Australian waters. Sea Forest is the first company to produce and scale Asparagopsis at a commercial scale. They are developing innovative ways to cultivate the seaweed on land and in the ocean. This is how it works:

    On the left side you can see how a boat farms seaweed in the ocean. Alternatively it can be grown in tanks on land. After it is harvested, the seaweed needs to dry. Sea Forest then produces a feed supplement for cattle.

    No, the milk and meat don’t taste like seaweed. And amazingly, the cows are more productive with this supplement. They need less feed because they are saving energy by not producing methane. A 2020 study found that methane emissions from cattle can be reduced by up to 98%:

    Animals whose diets contain 0.2% Sea Forest’s supplement will have methane reductions up to 98%.

    https://www.sciencedirect.com/science/article/pii/S0959652620308830?via%3Dihub#ack0010

    That is a very impressive reduction of methane! There are still a lot of open questions and scientists say there is not enough seaweed for all the cattle in the world. What I like most about Sea Forest is that they are acting now. We need climate solutions now and Sea Forest is one of the teams delivering. They are planning to sell the first supplements later this year.

    As with so many other amazing teams all over the world, Sea Forest is producing climate solutions right now. Their rapid and innovative approach is inspiring and I hope they succeed!

  • How a Small Grain Can Make a Big Impact

    How a Small Grain Can Make a Big Impact

    This week’s climate story brings us to the green rice fields of Thailand. As in many other countries, rice is a staple food here. But did you know growing rice causes a significant amount of greenhouse gas emissions?

    Traditionally, rice is grown on flooded fields called rice paddies. These paddies create ideal conditions for bacteria that emit methane. Why is methane bad? Methane has more than 80 times the warming power of carbon dioxide over the first 20 years after it reaches the atmosphere.

    Today’s story shows how rice farmers in Thailand and all over the world tackle global warming. Reducing and interrupting the period of flooding reduces emissions. This method is called “alternate wetting and drying” and this is how it works:

    Traditionally, rice fields are continuously flooded as you can see in the left picture. When irrigation is stopped, the water level slowly decreases, as shown in the center. On the right, the water level is about 15 cm below soil level, where the roots still get water. Once the water level gets lower, the fields gets flooded again and the process of alternate wetting and drying starts all over. This actually increases yields while farmers safe water and electricity to pump the water.

    Let’s get back to Thailand. A project funded by the climate finance program NAMA Facility will outreach to 100,000 rice farming households to shift from conventional to low-emission farming. They are implementing best practices from the sustainable rice platform :

    • Alternate wetting and drying: Mid-season drainage alone reduces methane emissions by 35 to 70 percent.
    • Laser land leveling: Fields are leveled with the help of lasers to reduce water usage and increase grain yield and quality.
    • Site specific nutrient management: Farmers reduce the amount of fertilizer and apply it based on local conditions and only when needed.
    • Straw and stubble management: Instead of conventional burning, rice straw and stubble get removed from the field and used for other purposes or incorporated back into the soil.

    In Thailand, rice farming has long traditions. The NAMA rice project works with the government and directly with rice farmers to change to new, sustainable farming methods. Here is a quote from Rampha Khamhaeng, a rice farmer from central Thailand:

    To be honest, at first I didn’t buy it….Now I tried it and it works — it’s the best way

    https://www.ft.com/content/8ff2b454-9390-11ea-899a-f62a20d54625

    What I like most about this project is that it reduces emissions and the same time safes farmers money by using less water, fertilizer, and energy. This is another climate solution that is not only more sustainable, but also safes money. Let’s hope many more farmers all over the world are switching to sustainable rice growing practices soon!
