Lab efficiency: Towards a greener future

Posted on by janet.crompton

The Laboratory Efficiency Assessment Framework 2020 (LEAF) marks the University of Bristol’s move to a greener future. Following on from the University’s ‘climate emergency’ declaration and 2030 carbon neutrality pledge, we’ve set a new ambition for 100% Green Lab Accreditation and institutional LEAF. This will make us the first University in the world to achieve this.

Labs impact the environment, in fact they have a greater environmental impact than offices by at least five times. They use more water and energy, produce larger quantities of waste and generally use more resources. In order to tackle this ever-growing problem LEAF was created with lab users in mind and sustainable thinking at the forefront. LEAF is an innovative tool used to drive sustainability and efficiency within STEMed labs.

In 2019 the LEAF national pilot took place involving 16 national Higher Education Institutions, including the University of Bristol. To gain LEAF accreditation each participating lab must meet a set of criteria to achieve Bronze, Silver or Gold accreditation. Through LEAF, each lab’s carbon and financial savings can be recorded as they progress.

The LEAF criteria cover all environmental aspects of the lab including circular economy and waste, procurement, business travel, equipment efficiency and chemical management. In addition to this, the criteria also include research quality, addressing international issues regarding the ‘reproducibility crisis’. LEAF differs from the previous Green Labs Initiative as it includes metrics that enable us to quantify tangible environmental and financial savings so that we can measure real time changes in line with the University’s 2030 carbon neutrality goals.

Research councils and funding bodies are also collaborating with the Higher Education Institutions taking part in LEAF with an aim for inclusion in relevant research grant proposals within two to three years.

The LEAF accreditation is designed for academic groups or facilities rather than whole departments and involves the technical community, students and research staff.

  • Creates a better understanding within our community of our science buildings and operations

 

How LEAF works

After signing-up to LEAF, participants are sent the LEAF Framework – an electronic workbook with a set of easy-to-implement actions.  For each accreditation (Bronze, Silver and Gold), participants need to fulfil certain criteria. The workbook provides useful links to help achieve the criteria and information on why these actions are important for improving lab sustainability.

Completing Bronze accreditation should only take an average of five hours, as most of our labs will already be running to Bronze standards. As you progress through Silver and Gold, criteria become more challenging and include categories such as minimising the amount of single-use plastic your lab uses.

There are also several special awards: Environmental Improvement, Environmental Hero, Innovation for Engagement and Community Action.

Throughout LEAF, participants are supported by the Green Labs Team and student LEAF volunteers (LEAVs), who have received environmental audit training. On submission of workbooks, laboratory audits can be organised, led by LEAVs. LEAF aims to improve student experience by providing volunteering opportunities and training. Alternatively, teams can also be audited by staff from Campus Division, or by peer assessment if they wish. On successful completion of the workbook and audit, labs will receive green accreditation status.

LEAF closes 13 November 2020, but teams can submit workbooks and complete audits at any point during the year, note workbooks can be submitted multiple times.

So, if you’re a Technician or academic and aren’t already actively involved in LEAF 2020, sign up now! If you’re a student and you’d like to volunteer with LEAF then sign up here.

This is an exciting time for Sustainability and especially for our University, being the first institution in the UK to declare a climate emergency and the first in the world to aim for 100% LEAF accreditation in all STEMed labs!

Is benchmarking the best route to water efficiency in the UK’s irrigated agriculture?

From August 2015 to January 2016, I was lucky enough to enjoy an ESRC-funded placement at the Environment Agency. Located within the Water Resources Team, my time here was spent writing a number of independent reports on behalf of the agency. This blog is a short personal reflection of one of these reports, which you can find here. All views within this work are my own and do not represent any views, plans or policies of the Environment Agency. 

Approximately 71% of UK land (17.4 million hectares) is used for agriculture – with 9.3 million hectares (70%) of land in England used for such operations. The benefits of this land use are well-known – providing close to 50% of the UK’s food consumption.  Irrigated agriculture forms an important fulcrum within this sector, as well as contributing extensively to the rural economy. In eastern England alone, it is estimated that 50,000 jobs depend upon irrigated agriculture – with the sector reported to contribute close to £3 billion annually to the region’s economy.
It is estimated that only 1-2% of the water abstracted from rivers and groundwater in England is consumed by irrigation. When compared to the figures from other nations, this use of water by agriculture is relatively low.  In the USA, agricultural operations account for approximately 80-90% of national consumptive water use. In Australia, water usage by irrigation over 2013/14 totalled 10,730 gigalitres (Gl) – 92% of the total agricultural water usage in that period (11,561 Gl).
However, the median prediction of nine forecasts of future demand in the UK’s agricultural sector has projected a 101% increase in demand between today and 2050. In this country, irrigation’s water usage is often concentrated during the driest periods and in the catchments where resources are at their most constrained. Agriculture uses the most water in the regions where water stress is most obvious: such as East Anglia. The result is that, in some dry summers, agricultural irrigation may become the largest abstractor of water in these vulnerable catchments.
With climate change creating a degree of uncertainty surrounding future water availability across the country, it has become a necessity for policy and research to explore which routes can provide the greatest efficiency gains for agricultural resilience. A 2015 survey by the National Farmers Union  found that many farmers lack confidence in securing long term access to water for production – with only a third of those surveyed feeling confident about water availability in five years’ time. In light of this decreasing availability, the need to reduce water demand within this sector has never been more apparent.
Evidence from research and the agricultural practice across the globe provides us with a number of possible routes. Improved on-farm management practice, the use of trickle irrigation, the use of treated wastewater for irrigation and the building of reservoirs point to a potential reduction in water usage.
Yet, something stands in the way of the implementation of these schemes and policies that support them: People. The adoption of new practices tends to be determined by a number of social factors – depending on the farm and the farmer. As farmers are the agents within this change, it is important to understand the characteristics that often guide their decision-making process and actions in a socio-ecological context.
Let’s remember, there is no such thing as your ‘average farmer’. Homogeneity is not a word that British agriculture is particularly aware of. As a result, efforts to increase water use efficiency need to understand how certain characteristics influence the potential for action. Wheeler et al. have found a number of characteristics that can influence adaptation strategies. For example, a farmer with a greater belief in the presence of climate change is more likely to adopt mitigating or adaptive measures. Importantly, this can also be linked to more-demographic factors. As Islam et al. have argued, risk scepticism can be the result of a number of factors (such as: age, economic status, education, environmental and economic values) and that these can be linked to the birth cohort effect.
This is not to say that all farmers of a certain age are climate-sceptics but it does point to an important understanding of demography as a factor in the adoption of innovative measures. Wheeler et al. went on to cite variables of environment values, commercial orientation, perceptions of risk and the presence of an identified farm successor as potentially directing change in practice . Research by Stephenson has shown that farmers who adopt new technologies tend to be younger and more educated, have higher incomes, larger farm operations and are more engaged with primary sources of information.
Yet, there is one social pressure that future policy must take into account – friendly, neighbourly competition. Keeping up with the Joneses. Not wanting Farmer Giles down the lane knowing that you overuse water in an increasingly water-scarce future. This can be harnessed within a system of benchmarking. Benchmarking involves the publication of individual farm’s water use, irrigation characteristics and efficiency and farming practice. Although data is supplied anonymously, individual farmers will be able to see how they measure up against their neighbours, competitors and others elsewhere.
Benchmarking is used in other agricultural sub-sectors. A 2010 survey found that 24% of farmers from different sectors used benchmarking in their management processes. This is particularly evident in the dairy sector, where both commercial and public organisations use the methods as a way to understand individual farm performance – an important example of this would be DairyCo’s Milkbench+ initiative. In 2004, over 950,000 hectares of irrigated land in Australia, 385,000 hectares in China and 330, 000 hectares in Mexico were subjected to benchmarking processes as a mean to gauge their environmental, operational and financial characteristics.

The result is that irrigators would have the means to compare how they are performing relative to other growers – allowing the answering of important questions of ‘How well am I doing?’ ‘How much better could I do?’ and ‘How do I do it?’ Furthermore, this route can be perceived as limiting the potential for ‘free-riding’ behaviour within a catchment as well emphasise the communal nature of these vulnerable resources. We’ve all seen ‘Keeping up with the Joneses’ result in increased consumption – benchmarking provides us with an important route to use this socialised nudging for good.
