Following oranges through agri-business supply chains

by Charlotte Selvey

Seeing as this is CAER’s first blog post, (and what a privilege it is to be CAER’s first blogger) I decided to start off a trend of posts to briefly describe what each of the department’s PhD students are currently researching. There is a huge diversity of exciting projects which range from developing conservation management techniques to protect the CR Mauritian Olive White Eye (Gwen Maggs) to understanding the importance of biodiversity in supporting the ecosystem services of apple orchards in Kent (Sean Webber). Not only will this blog thread inform the world outside of CAER what we are all up to, but it will help us understand what each other are actually doing too!

I am still fairly new to PhD life, about 7 months through and only just starting to find my feet. So unfortunately there are no profound results from me yet but I have outlined some areas of interest of which I would like my PhD to focus on and which I could garner some interesting results in a few years maybe.  Whether these areas of interest will completely change is currently unknown and I would prefer to keep it that way, for sanity reasons.

The topic of my PhD is one very relevant to CAER’s general interests: ecosystem services. This buzzword is everywhere at the moment: within academia, government policies and even multinational corporations that rely on these services provided by the environment to support their global products. One company particularly interested in finding the business value of these ecosystem services is Pepsico who are the industry partner of my PhD.

Pepsico are the second largest food and beverage business in the world in terms of net revenue. In the UK Pepsico are best known for their Copella, Walkers Crisps, Quaker Oats and Tropicana brands. Pressures are rising from consumers and charities who are targeting companies like Pepsico, Nestlé and Kellogs to source their ingredients more sustainably – especially considering the vast amount of land used in order to grow the ingredients those companies go on to sell. Campaigns and petitions such as Oxfam’s Behind The Brand and Sum Of Us’ palm oil campaign both name and shame Pepsico for not being responsible in making sure their suppliers are sourcing sustainably. Every ingredient Pepsico source will need scrutinising, but I don’t have enough time to look at all ingredients during my PhD so I decided to start with one of the most complicated supply chains: oranges.

Supply chains are complicated at the best of times, with farmers producing ingredients all over the world, middle men providing different services, processors and packagers, buyers and then final consumers. For a brand to be classed as sustainable, audits and compliancy checks must be undergone at each level in the supply chain to ensure each person in this confusing, international network are all acting sustainably. In the past, large international corporations like Pepsico have benefitted from relying on external sources to buy their ingredients, that way not having to ask any questions as to where it came from – as long as the price is right. But with consumers becoming ever more savvy about their environment and the impacts bad farming practices could have on natural habitats and endangered species, these large corporations are being forced to take on more responsibility.

Where do I start? It seems quite practical to firstly find the orange groves the oranges come from to produce Tropicana destined for the European market. This has turned out to be a tricky task. Although they are mostly from São Paulo State in Brazil, their exact locations are unknown which makes assessing any environmental risks very difficult. If management techniques and inputs such as fertilisers and insecticides are unknown this means there is an unknown impact those Tropicana oranges are having on biodiversity both on farm and in the surrounding landscape as well as the ecosystem services those orange groves might rely on: water and nutrient cycling, pollination or pest control from praying mantids!

The overall aim of my research is to provide international corporations, of similarly confusing supply chains, with a process to follow or ‘conceptual framework’ to help them identify where environmental, reputational and eventually economic risks lie within their supply chain. If being environmentally sustainable can be economically viable and profitable then surely this is an easy move for businesses to make? Nurturing nature and being ‘green’ should not only be practiced when times are economically viable to do so, but it should be engrained into business plans to ensure long term sustainability of a company – especially those which rely on natural resources or ‘natural capital’ to produce food and drinks products sold worldwide.
