Experimental Rice in Bali Increases Yields & Decreases Emissions

You love rice, everyone loves rice and we need more of it. Growing populations and the impact of the climate crisis on crops raises the stakes of rice cultivation. As a species we need to keep rice cheap, plentiful, and accessible to ensure a stable global food supply. India has stopped exporting rice which means other nations need to step up their exports. In Bali they recently ran an experiment in water rice fields and found ways to reduce water consumption and improving yields. This is a good finding for such a popular food.

The results at the end of the first harvest were astounding, the researchers say. They found that in the drained field, the release of GHG had dropped by 70%, and the farmer who owned the demonstration plot saw his crop yield in the drained field rise by more than 20%. The researchers knew why the methane had been reduced, but initially they couldn’t work out why the crop was so bountiful. Then Lansing reflected on a study he’d carried out in 2005 on the impacts of fertilizer runoff on coral reefs. By draining the field, he concluded, the fertilizer remained in soil rather than being washed into the river system.

Better Solar Helps Bitter Hops

Agrivoltaic setups aren’t new to regular readers of this site as we’ve seen many times that certain crops benefit from the shade solar panels provide; and, the solar panels benefit the farmers by producing clean energy. Now we know that hops, which flavour beer, thrive under solar panels. A German experiment with a special solar setup for hops has proven more successful than expected since the hops fared better against disease.

Which crops thrive under solar panels depends on many factors, and for a crop like hops a default solar field setup is not a good one. Hops like to grow straight up which means that the solar panels need to be elevated high off the ground. The hops then grow up to the solar panels and get lots of benefit from the cooling effects of the panels themselves.

The pilot project — a collaboration between Wimmer and local solar technology company Hallertauer Handelshaus — was set up in the fall of last year. The electricity made at this farm can power around 250 households, and the hops get shade they’ll need more often as climate change turbocharges summer heat.

Solar panels atop crops has been gaining traction in recent years as incentives and demand for clean energy skyrocket. Researchers look into making the best use of agricultural land, and farmers seek ways to shield their crops from blistering heat, keep in moisture and potentially increase yields. The team in Germany says its effort is the first agrivoltaic project that’s solely focused on hops, but projects have sprouted around the world in several countries for a variety of grains, fruits and vegetables.

Prairie Strips Save Farms

- Adam Clare


Farmers are on the front line of climate change and to some extent they are accelerating it (deforestation and extensive pesticide use), but smart farmers are fighting climate change and improving their crop yield at the same time. A very successful natural intervention farmers can use are known as praire strips. These are long thin strips of land on a farmer’s field that hosts native species and provide lots of benefits to the surrounding land. They attract insects that help crops, help retain water, and keep the soil healthy in a way that chemical interventions can’t.

Insect and bird populations are more than 2x in prairie strips compared to mono-crop fields – providing vital defense against pests and other ecosystem services

Pollinators increase at around the same rate

Prairie strips turn a veritable green desert into a thriving ecosystem

Start a Small Garden This Spring

- Adam Clare

Anyone can be a gardener and you can too! All you need is a balcony or small plot of land and you can start growing your own food. To some people, the very idea of caring for other living things can be scary – what if all the plants die? Here’s the trick: start small and grow plants that can thrive in your area naturally. No green thumb is needed if you plant local.

An expert gardener has provide ten simple tips for first timers. You can do it!

2. START SMALL

If you are planning how to start a vegetable garden in your backyard then the potential size is likely dictated by what yard space you have. Some people may have grand plans when planning a kitchen garden, though if you are new to vegetable gardening then it may be best to start with a small space.

Starting with focusing on small vegetable garden ideas allows you to learn and get that satisfaction without the risk of getting frustrated by a large vegetable garden that gets weedy and out of control quickly. By starting small it means you can get a feel for how long things take to grow and nurture and the time involved in weeding, watering, fertilizing and harvesting.

It can take up more time than first expected and no-one wants to get disillusioned by turning over a huge space in their backyard to a vegetable garden that they don’t actually have the time in their busy lives to tend. If you do want to transform a large area, then it can be done slowly or sections not cultivated covered with thick cardboard or plastic to smother weeds.

Catching Illegal Fishers

- Adam Clare

Many people reduce their meat intake (which is good!) by swapping it with another animal protein source of fish. The problem here lies in how fishing is done around the world and the crimes committed by too many fishers. Indeed, crime on the high seas is alive and well with fishing vessels partaking in swaths of illicit behaviour. This all sounds bad, but the good news comes down to preventing it.

Indeed, researchers have published the results of a large effort to track when, where, and sometimes why fishing vessels turn off their tracking systems known as AIS. This is fantastic because it will help nations enforce the rules of the ocean by stopping illegal maritime activities.

AIS disabling is also strongly correlated with transshipment events – exchanging catch, personnel and supplies between fishing vessels and refrigerated cargo vessels, or “reefers,” at sea. Reefers also have AIS transponders, and researchers can use their data to identify loitering events, when reefers are in one place long enough to receive cargo from a fishing vessel.

It’s not unusual to see fishing vessels disable their AIS transponders near loitering reefers, which suggests that they want to hide these transfers from oversight. While transferring people or cargo can be legal, when it is poorly monitored it can become a means of laundering illegal catch. It has been linked to forced labor and human trafficking.
