Grasslands in disaster: Why the meals trade ought to act now

North America has misplaced 2.6 million acres of intact grassland in a single 12 months – an space bigger than Yellowstone National Park. Land has been cleared primarily to make manner for wheat, corn and soy manufacturing, a brand new report from WWF reveals.

Globally the issue is extra vital nonetheless. Worldwide grasslands are beneath extreme menace from ongoing degradation as land is transformed to develop crops. According to the World Commission on Protected Areas (IUCN), grasslands are thought-about ‘probably the most altered terrestrial ecosystem on the planet’ and are recognised as ‘probably the most endangered ecosystem on most continents’.

In distinction to commodities pushed deforestation, to this point, grasslands have largely been ignored in sustainable improvement agendas regardless of the size and pace at which they’re being misplaced. Without a charismatic orangutan talisman for customers to rally round, the implications of this land-use change have been largely neglected.

This might be about to alter. At the current UN Food System Summit, the WWF issued a name to kickstart grassland conservation.

“The consciousness of grassland loss and the impacts it has haven’t been on the radar in a significant manner, however that is altering and we’re seeing extra curiosity to know the problem and account for it,”​ mentioned Patrick Lendrum, Science Lead for WWF’s Northern Great Plains program.

Lendrum believes that grasslands will ‘completely’ grow to be a touchpaper problem for customers sooner or later, in a lot the way in which that deforestation is as we speak.

“Nearly 50% of grasslands have skilled some type of degradation​ be it conversion, invasive species, overgrazing, local weather change or altered hearth regimes,”​ the conservationist informed us. “Grassland conservation is of world concern and everybody must be working collectively to unravel this downside to the good thing about local weather change, biodiversity, different ecosystem providers, and the livelihoods that rely on grasslands.”

Biodiversity loss and local weather affect

Covering round 8% of the planet’s landmass, grasslands have been ‘as soon as residence to among the largest assemblages of wildlife the Earth has ever recognized’, IUCN revealed. But with solely 4.5% of grasslands inside protected areas, that is beneath menace.

Conversion of grasslands is going on on ‘high-quality habitat’ for numerous species, current analysis centered on the US concluded​. The research advised conversion is producing ‘marginal yields’ – as a result of virtually 70% of transformed lands ship yields under the nationwide common – and that is coming with ‘excessive prices to wildlife’. 

“Grassland birds have skilled the biggest decline of any guild. Seventy-four % of species are declining​. This is largely attributed to habitat loss and pesticide use. The checklist goes on and on be it pollinators, birds, mammals, or aquatic life, the consequences of that are felt all the way in which right down to the hypoxic zone within the Gulf of Mexico,”​ Lendrum pressured. 

Other ecosystem providers, notably carbon sequestration and soil erosion management, are additionally being hit by grassland degradation.

One research locations the soil carbon loss ensuing from grasslands conversion at 107 kg CO2e per 12 months​.  To put it in context, that’s equal to the quantity of CO2 launched into the ambiance by 23m automobiles being pushed for a 12 months.

“While estimates of soil carbon are troublesome to calculate at such a big scale and there’s some variation amongst researchers, there isn’t any doubt that conversion of grasslands contributes to local weather change in a big manner,”​ Lendrum informed FoodNavigator.

Industry and stakeholders should step up: ‘Action must happen earlier than later’

WWF is already working with companions within the meals and beverage sector to take a look at how they’ll take a extra pro-active function within the safety of grasslands. Lendrum want to see targets round zero conversion of grasslands put in place, just like these which have been established to stamp out deforestation within the provide chain.

While companies ought to speed up motion on grasslands, Lendrum insisted ‘it’s not simply as much as the meals trade’.

“Businesses want the instruments to make the adjustments vital and that accountability lies with authorities businesses, lecturers, NGOs, and others along with the meals trade,”​ he advised.

“The results of local weather change are upon us and being skilled by everybody throughout the globe. Action must happen earlier than later and avoiding grassland conversion is among the most cost-effective methods to sluggish carbon emissions.”

As with work being undertaken on deforestation, one ‘massive problem’ impeding progress is an absence of traceability via the provision chain, which means at present even the place companies need to act, they’re prone to discover implementing commitments troublesome. Lendrun believes collaboration can be an necessary unlock right here: “We want corporations and commodity teams to with us on this journey to make that attainable.”

The complicated hyperlink to animal agriculture

Animal agriculture is usually flagged as one of many meals system’s largest local weather impacts, with the UN’s Food and Agriculture Organization placing emissions from the sector at 14.5% of all GHG emissions.

Grasslands degradation is being pushed by the conversion of land to develop money crops, akin to wheat, corn and soy. Looking on the US context, most of those crops are destined to feed animals, a lot of that are being reared in intensive programs.

Over 70% of the US soybean crop was used for animal feed, with 15% going to human meals and 5% used for biodiesel, in 2015. In 2020, greater than thrice the quantity of corn used within the US went to animal feed than human meals. Most crops grown on degraded grasslands are subsequently prone to make their manner into the feed chain reasonably than the meals chain.

However, livestock agriculture can play an necessary function in grasslands conservation. “Extensive livestock grazing is the first grass-based economic system that retains grasslands intact and maintains them in a wholesome situation when correctly managed,”​ the WWF’s Lendrum famous.

“Sustainable livestock grazing gives livelihoods, meals and fibre, ecosystem providers like carbon storage, diminished downstream flooding, clear water and wildlife habitat.”

This complicated image and the duality of the hyperlink between animal agriculture and grasslands degradation make it ‘very troublesome’ to speak a couple of ‘one-size matches all strategy’, Lendrum defined.

“Sustainable intensification of manufacturing, akin to regenerative agriculture and nil new conversion, along with crop diversification and extra meals being grown for direct human consumption are all wanted to feed the rising inhabitants whereas stopping land use change and nature loss.”
