According to a new study, the survival rate of rainforest seedlings is higher in natural forests than those that have been logged — even three decades following tree restoration projects.

An international team of researchers led by the United Kingdom’s University of Exeter tracked more than 5,000 seedlings in the Danum Valley Conservation Area and surrounding Ulu Segama landscape in North Borneo for one-and-a-half years, a press release from University of Exeter said.

The landscape contained natural forest as well as areas that had been logged 30 years earlier. Some had been restored with tree planting and other methods, while others were recovering naturally.

“Our findings suggest that seedlings are experiencing stress in logged forests. This could be due to changes to the canopy structure, microclimate and soil, with current restoration treatments insufficient to eliminate this stress. In particular, highly specialised species seem to struggle to survive, leaving communities with reduced species diversity compared to intact forest,” said Dr. David Bartholomew, who was based at University of Exeter while conducting the study and is now with Botanic Gardens Conservation International, in the press release.

Logged forests have reduced seedling density, reducing the probability for the next generation to emerge. David Bartholomew

Across the study region, a “mass fruiting” had been triggered by drought. It caused trees to drop their fruit all at once, followed by the emergence of new seedlings.

Early on, both the restored forest and the natural forest had relatively high seedling numbers in comparison with a forest recovering naturally from logging, which suggested fruit production was enhanced by restoration activities.

But seedlings in the restored forest had low survival rates. By the time the study was finished, the naturally recovering forest as well as the restored forest had similarly low seedling numbers. In the natural forest, however, seedling populations stayed higher.

The results demonstrated that forest regeneration may be affected by various factors contingent upon the restoration approach. For example, seedling survival in areas where planted trees have reached maturity and seed availability in sites that are naturally recovering from logging. The variations could have longer-term effects on how forests are able to perform carbon sequestration and other important ecosystem services.

“We were surprised to see restoration sites having lower seedling survival. After such a productive fruiting event in the restored forest, it’s disappointing that so few were able to survive – and to think what this might mean for the long-term recovery of different tree species,” said Dr. Robin Hayward, who conducted the research while pursuing a Ph.D. at the University of Stirling, according to the press release.

Even though it has been shown that restoration benefits biomass accumulation, the findings indicated that it is not yet enabling the full establishment of next-generation seedlings.

“Rainforests are complex systems and there are many possible explanations for our results. For example, animals that eat seeds – like bearded pigs – may be drawn into restored forest patches to eat the more abundant seeds and seedlings, rather than moving into adjacent poor-quality logged forest. In natural forests, animals potentially move more freely and so do not exhaust seed supplies in the same way,” said Daisy Dent of ETH Zürich and the Smithsonian Tropical Research Institute in Panama, in the press release.

Selective logging is widespread throughout the tropics, but long-term forest recovery is essential to the maintenance of high biodiversity and carbon stocks. Low seedling survival rates three decades later raise concerns about possible regeneration failure in future tree generations.

“Together, these results reveal there may be bottlenecks in recovery of particular elements of the plant community. We are now progressing this research into the various stages of the regeneration process – fruiting, germination, establishment and causes of mortality – to help understand which mechanisms are driving the patterns we have observed and how we can better assist forest regeneration and support the long-term sustainability of degraded forests,” said Dr. Lindsay F. Banin of the UK’s Centre for Ecology & Hydrology, in the press release.

The study, “Bornean tropical forests recovering from logging at risk of regeneration failure,” was published in the journal Global Change Biology.

It draws attention to the urgency of careful design, adaptive management and monitoring of restoration projects to ensure they are able to recover long-term biomass carbon and biodiversity. This is essential to meeting global targets like those set forth in the United Nations Decade on Ecosystem Restoration and the Kunming-Montréal Global Biodiversity Framework.

Traits and characteristics in plants that determine plant functionality could be the answer to understanding low seedling survival rate, as they can show which resources plants are having a difficult time accessing.

The study found differing plant traits in intact forests and logged areas, which indicated that certain species may be having a hard time surviving in areas that have been disturbed, and some must adapt the way they grow. This could affect ecological functioning and biodiversity in the long-term.

“This study captures just 18 months after one fruiting event. Longer-term research is required to understand the full effects of historic disturbance, and how to enhance seedling survival,” the press release said. “Here, intact forests are dominated by a tree family, the Dipterocarpaceae, which along with many other tree families, fruits in large inter-annual episodes known as masting events. These cyclical events have important cascading effects on food availability for animal species.”

Today’s quote is from author Ken Webster and philanthropist Ellen MacArthur: “Ordered, complex, intertwined mutually interdependent systems are the new normal.”

Humanity is learning to mimic nature. As we embrace complexity, humanity can evolve new solutions to providing itself food, shelter, and waste elimination.

Ken Webster wrote The Circular Economy: A Wealth of Flows, which was edited by Ellen MacArthur, founder of the Ellen MacArthur Foundation, a charity committed to creating a circular economy.

My Weekly Meal Planning System That Prevents Food Waste

Published

Last Updated on May 14, 2026

Meal planning is a great way to reduce both packaging waste and food waste, because you’re thinking ahead. It can also help keep grocery costs down because you’re actively planning the menu for the week, not making impulse buys.

But a lot of people (myself included) fail at it for one simple reason: We’re thinking about meals and not ingredients.

My Weekly Meal Planning System That Prevents Food Waste

For example, if my meal plan says Tuesday is lasagna night, how will I know if I’m still craving that by Tuesday? Keeping a flexible meal plan will help you succeed.

Once you have a meal plan you love, you can get to actually prepping your ingredients for the week. Here’s how I create a weekly meal planning system that I can actually stick to. Bonus? My tips for actual meal prep!

meal planning vs. prepping

Lets first take a moment to separate these two terms, as I’ll be talking about both.

Meal planning is simply the act of planning out what you’ll eat for the week. This can be in regards to your breakfast, lunch, dinner, or even snacks.

Meal prepping is when you cook your food for the week in advance. If you’d like to meal prep, it’s a good idea to have a meal plan. However, you don’t have to meal prep to meal plan.

Both help you save money and reduce waste in the long run. For example, lets say you want carrot soup on the menu this week. Knowing the ingredients you need to make it helps you stick to a grocery budget. Plus, you can save even more by using up whatever’s already in your fridge!

My Weekly Meal Planning System That Prevents Food Waste

meal planning

how do you create a meal plan?

The first step is to make a master list of all of your favorite recipes. The ones that you love, the ones your family loves, and most importantly – the ones you know how to cook.

Here are a few of my favorites for inspiration:

  • Shepherds Pie
  • Burgers
  • Mac & Cheese
  • Quesadillas
  • Fajitas
  • Chicken/Eggplant Parm
  • Lasagna
  • Fried Rice
  • Beef/Mushroom and Broccoli
  • Cheese Steak/Balsamic Mushroom Subs
  • Sloppy Lentil Joes
  • Caeser Salad

You can write these on a notepad, on your phone, or on the computer. Refer to this master list whenever you’re planning meals for the week – and don’t be afraid to add meals to it over time.

It’s also a good idea to jot down some of your favorite breakfasts, lunches, and snacks – not just dinner. This will help you better plan your grocery haul for the week ahead.

Try to stick to one particular day to grocery shop every week – be it on Tuesday nights or Saturday mornings. Whatever works for you.

You’ll want to check the calendar and make sure there’s no upcoming events in the week ahead. This will keep you aware which nights you won’t be cooking.

You may also want to factor in weather and seasons – for example, I love eating soup on cold days! But hot days, I’d prefer something lighter, like a tofu stir fry.

Now comes the fun part – actually writing your meals for the week! Make sure you have that master list of recipes you made on hand, then start jotting down what dinners you’d like to eat.

You don’t have to set specific days for when you serve these meals, unless you want to. Feel free to shuffle the meals around, depending on what you’re in the mood for.

Next, make a grocery list based on the meals you’ve written down. You can organize the list into sections of produce, pantry, protein, etc.

For me, proteins will include beans, lentils, seitan and hummus. And for produce, I always try to stick to what’s currently in season – like sweet potatoes in the fall, lettuce in the summer.

Once you’ve done your shopping, you can come home and prep a few items to make your life easier during the week. For example, if one of your recipes calls for kale, having it washed, chopped, and properly stored will make it super easy to add into your cooking.

what about breakfast, lunches and snacks?

For me, breakfast, lunch and snacks are often more consistent than dinner. I could eat a sandwich every single day and be happy.

Peanut butter and jelly with chips was my go-to lunch from elementary to high school. So I’ve decided to lean into that, focusing on simple breakfasts and lunches that keep me full.

Knowing what you like to eat is a good place to start! I love high protein yogurt jars for breakfast, sandwiches for lunch, sliced apples, hummus, and chopped veggies for snacks.

If I don’t prep these items ahead of time, I have a bad habit of waiting until 2PM to eat. Which leads to really poor food choices. 

If you’re also like this, chances are meal planning and prepping doesn’t have to just begin and end with dinner.  

Figure out what it is you struggle with most before deciding which foods, ingredients, and meals to prep for the week. Ask yourself what would be more convenient to have ready to grab-and-go: breakfast, lunch, dinner, or snacks? Perhaps a combo of the four? 

Your job and schedule can also influence this decision. For example, if you’re working from home, you may have more time to whip up breakfast than someone who needs to be at work at 8AM. 

My Weekly Meal Planning System That Prevents Food Waste

meal prepping

I personally like to meal prep ingredients instead of meals to give myself freedom and reduce waste. This helps get food on the table fast.

And always check your fridge and pantry before grocery shopping. Try planning your menu around what’s already available, then grocery shop for the rest of the ingredients you’ll need to complete each dish.   

I recommend dedicating 2-3 hours a week to meal prep. You can make it fun by turning on the TV, listening to music or a podcast. For me, meal prepping means peeling and chopping carrots, washing and cooking my vegetables, etc.

However, feel free to make full-on meals if you know you won’t have time otherwise. I’ll do this with my breakfast yogurt jars, veggie sandwiches, and snacks on a Sunday afternoon.

Setup glass snapware to contain whatever it is you’re making, and always ask yourself if you have a carb, a protein, a fat, and fiber. This will keep your meals balanced and help you stay full longer.

And if you’re short on time, just focus on getting your vegetables all washed, chopped, and stored in glass containers. No need to cook anything. This will make your life so much easier when you go to cook after a long day at work.

mistakes to avoid

Here are a few mistakes to avoid when it comes to meal planning and prep:

  • Not checking your weekly schedule first.
  • Using containers that don’t seal or close properly.
  • Making cuisines and recipes outside your comfort zone / your family’s preferences.
  • Making servings too big or too small.
  • Trying to do it all (maybe start out by prepping just one or two meals for the week instead of all 5 days)

how to keep it budget-friendly

Definitely work with what’s in season! I find that shopping for tomatoes in summer tends to be cheaper than in winter, because there’s an abundance of them. 

Always try to prioritize local farmers markets and CSA boxes whenever possible. You can also try growing your own produce, joining a local community garden, or even just doing an herb container garden to save money.

Also, shopping at low-cost grocery stores or farmers markets can help cut costs. Looking for discounts, coupons, and sales is also ideal.

I love shopping the discount section of my grocery store – sometimes they’ll have imperfect produce at half price, and I always scoop that up first.

You’ll want to also prioritize what’s in your fridge already, and what’s about to go bad. Have some sad looking celery? Toss it into a soup for the week. Stale bread? French toast casserole it is for breakfast.

And factor in leftovers too! If you have some rice that needs to be used up, make sure to prioritize a dish in the beginning of the week that requires it.

That goes double for food scraps – don’t toss out all your vegetable ends and peels. You may be able to make them work overtime by making veggie stock for your meal prepping!

You may also be surprised at what’s edible – like beet tops, carrot tops and celery leaves. Here are some other recipes to help you reduce food waste.

benefits of meal prep

There are so many benefits to meal prepping, but the biggest one is peace of mind. You don’t have to think about what you’ll eat every single day, because half (or all!) the work is done for you.

And, if you’re checking your pantry and fridge before meal prep, you’re probably reducing a lot of food waste. Because you’re going to prioritize using up what you have.

Some more benefits to meal prepping include:

  • Big time saver.
  • Helps prevent drive thru or take out orders because you have food at your fingertips.
  • You’ll know exactly what goes into your food.
  • Zero waste food, so little to no waste.

Best of Sustainability In Your Ear: Algenesis & Blueview Launch the Algae-Based Polyurethane Industry

Published

on

Travel back in time to hear the origin story of Algenesis, which started as two companies in one, a biotechnology innovator and footwear maker. Today, the company is a leading maker of bio-based plastics. In 2023, Algenesis had just begun making a new, sustainable material and found a clever way to prove its utility to get big companies to embrace it. Join the conversation hear why a shoe company was the best a practical application to prove the value of a plant-based, compostable bioplastic foam. Stephen Mayfield, a professor of Biology at UC San Diego and director of the California Center for Algae Biotechnology, invented Soleic, an algae-based rubbery foam material that can be used in footwear, surfboards, and other products in the place of petroleum-based polyurethane foam. He launched Algenesis, a biotechnology-based materials science company to commercialize Soleic.

But shoe companies did not come running to use Soleic, which biodegrades completely in sea water and compost piles. Along with Algenisis president Tom Cooke, a footwear and apparel industry veteran who had worked for Reef and Vans, Steve launched Blueview Footwear, maker of the world’s first compostable shoe. Steve and Tom join me today to talk about the evolution of Algenesis and Blueview, as well as the many materials Soleic could replace across a variety of product categories. The companies have also developed compostable, plant-based fabrics and a bioplastic waterproofing technology that biodegrades into organic material in a home compost pile. You can learn more about Blueview Footwear at blueviewfootwear.com and its parent company Algenesis Materials at algenesismaterials.com.
