As we have been in the mist of Brexit chaos over the past few weeks, here at BEES we thought it was important to explore how this uncertainty could impact UK agriculture. In September 2020, a member of our team got the chance to attend The future for agricultural land use’ conference which examined the next steps for agricultural land use, policy and regulation in the UK. This informative conference left us wondering just how much our agricultural system will change because of Brexit and which methods we will utilise in the fight to make farming more sustainable.


Currently, we are experiencing an ecological crisis associated with our farming methods; agricultural intensification, which primarily consists of monocultures, has led to a startlingly loss of ecological heterogeneity and ecosystem diversity. It is well known among scientists that reduced biodiversity puts species at greater risk of extinction from pressures such as climate change. To make things worse, this form of agricultural system also reduces ecological connectivity, or in other words, the ability for animals (and even some plants) to move freely between habitats. Connectivity is vital in the survival and migration of many species as it allows access to varying resources and promotes diversity through interpopulation breeding (gene flow). In this post we will be assessing a particular type of farming practice that has been shown to have great benefits for improving biodiversity and connectivity - agricultural set-asides.


What are set-asides and how do they work?


Set-aside land can be defined as any section of farmland which has been taken out of production. They are usually characterised by grassland strips at the boundary of agricultural fields. Set-asides were originally implemented in 1992 to combat over production of crops and reduce soil erosion on farmland. Since 2008, most EU countries have abolished obligatory set aside management strategies to keep cereal production in pace with increasing demand. In some regions however (e.g., Hungary), this concept has been redesigned as a tool for reducing decades of biodiversity decline.


Research on agricultural set-asides has shown they support higher population densities and species number of animals such as birds, insects, spiders, and several plant species. Studies also show incredible co benefits for connectivity, in one study connectivity improved in 74% of landscapes, as shown by range expansion rates. This particularly impacts certain species such as birds and butterflies but also benefits mammals, flowering plants, arthropods and even soil microorganisms.


Consequently, many wildlife groups now stand behind retaining this scheme as a crucial method for preserving species numbers through increasing diversity and ecological connectivity. If these schemes come to an end, many conservation groups fear hugely detrimental impacts on wildlife. For example, the Royal Society for the Protection of Birds worries that Skylarks, Yellowhammers, Linnets and Stone Curlews are just some of the species that would suffer greatly from the loss of the set-aside areas.


Which species benefit most? When is it a viable strategy?


An important thing to consider with this dilemma is which species will benefit the most. The short answer is, it depends on a range of factors such as: location, size, agricultural policy in a given region, and duration of time land has been set-aside.

The British Trust for Ornithology (BTO) has explained that the use of set-asides may fill the "hungry gap" when farmland birds find it hard to find seed in the first two months of ploughing in mid-February. Paul Stancliffe, a BTO ornithologist explained: "It's that hungry gap we're most concerned about, something that would fill that gap would be great as far as the birds would be concerned."


Some species actually rely on the set-asides as a lifeline from extinction. The Little Bustard Tetrax tetrax has been driven to extinction by intensive agriculture in at least 11 European countries; the only remaining French population has merely 10% of its pre 1990 population levels and depends on set-asides for survival.

Set-asides also been found to be important for soil health as studies show higher diversity of woodlice species in set-aside fields compared with neighbouring wheat fields. This diversity is vital for ecosystem services as these organisms decompose dead plant material - a key step in the nutrient cycling process.


Problems and future considerations


Despite the urgent need for these set-asides to increase ecological connectivity and prevent extinction of certain species, or at least preserve a minimum level of populations of endangered species, like all conservation strategies, it is not perfect. The scheme fails to protect some species that urgently require conservation intervention as they have been found to have little impact on low density, low dispersal butterfly species which are at greater risk than high density, mobile butterflies for example.

Studies also show that the older and larger the set-aside the more effective it is, but can many farmers afford to lose a large portion of their land for a considerable amount of time? We need more research into economic context and how these schemes effect the whole ecosystem in the context of entire landscapes. Is the trade off between economics and environment enough of a catalyst to drive changes in agricultural policy?


We must also consider the urgent need to reduce Carbon output from agriculture, the UK aims to reduce emissions by 57% by 2030, relative to 1990. Unfortunately, there is little evidence that this scheme will help reach that target so, do we need a more impactful approach? Some would argue we should be utilising methods that combat emissions whilst producing co-benefits for wildlife conservation on a much larger scale. For example, Agroforestry is a method that has been adopted by Brazil and has been hugely successful in exceeding agricultural emission targets. Utilising an area twice the size of the UK, trees and shrubs were grown alongside cropland, resulting in Brazil achieving 115% of their overall target by 2018. The key to their success it seems was to convince farmers that strong ecological improvements can bring great economic benefits. This logic may have some appeals too for UK farmers, if scientific research could generate arguments in favour.


This begs the question of what the future of agriculture will look like post-Brexit and how we will use this opportunity to implement our own policies to become more sustainable. Should we be focusing on strategies like set-asides which fail in generating wider scale impacts and only benefit a few species? Or are all initiatives that help preserve our wildlife necessary and valuable, and should be implemented as such? Even if the answer to that question is nothing but simple, we would be glad to read your opinion about it!

The word ‘staycation’ took on a whole other meaning this year, as overseas travel was off the cards and most of us were forced to get out and experience the landscapes on our doorstep. For me, this has been a real eye-opener in terms of exploring our great British countryside- and what a treat it has been! From the green, rolling hills of the Yorkshire Dales, to the sheer white cliffs of Dover, there is so much to be astounded by.

It is encouraging to see so many people finding great joy in holidaying at home and appreciating all the truly underrated beauty this country possesses. If we want to continue as a land rich in biodiverse flora and fauna, experiencing and learning more about the UK’s wildlife and the issues that lead to environmental decline is vital. It is clear that a greater understanding and appreciation of nature leads to a stronger drive to protect it. By igniting wonder and gratitude for our country’s natural landscapes and the weird and wonderful creatures that inhabit it, we reinforce the need to protect and conserve these fascinating yet fragile ecosystems.


But, conserving the local environment isn’t the only benefit of the staycation. Reduced travel distance not only reduces your carbon footprint by avoiding air miles, but it also means no airport hassle, delayed flights, or pesky jet lag! If you do travel via air, be sure to check out carbon offsetting. Staying close to home also helps support the UK economy and by visiting independent hotels, cafes, and restaurants you are supporting vital local businesses. Don’t forget, as an added incentive, you can also bring your pets! There really is no downside to choosing to opt for the staycation this year (except, maybe the rain).

There is light at the end of the tunnel...

Hello everyone,


We hope you are all keeping safe and well, and staying positive in these trying times. Hopefully we can brighten up your day a little with some good news about our BEE a Nature Guide training course!


Since we last posted a progress update at the end of August, we have been working hard to adapt the course programme in response to COVID-19, so that we can still deliver a high quality nature guide training course whilst making sure everyone remains safe and healthy.

In order to ensure your safety as well as the safety of our staff, we have restructured the course programme to remove all indoor face-to-face sessions. Most of our subjects will now consist of an outdoor guided walk, generally a half day every other Saturday, combining practical and theoretical components, followed by an online session covering the rest of the theory. A small number of the subjects will be online only. Additional learning resources and support will be made available to you through our new online learning platform.

Now that we have finalised the format of the Course, we are pleased to be officially accepting bookings and payments! Those of you that have previously registered an interest in the Course on our website will have received an email with further information, including our COVID-19 policy and risk assessment, which can be viewed here, detailing the measures we have put in place to keep you and our staff safe.


We are all very excited to finally be able to launch the first BEE a Nature Guide Courses! Initially run in two counties, Suffolk and Norfolk. The Suffolk course programme is scheduled to start on 16/01/2021, the Norfolk course programme on 30/01/2021.


You can read more about the Course and sign up here.


Please share this post with your friends, relatives, colleagues, or anyone you feel may be interested in learning more about nature and joining us.


We look forward to meeting you soon!
