A First Introduction to SHERPA

I’ve been in some very tough meetings with farmers over the years. The most difficult ones were inevitably those where, in our wisdom, and in an attempt to be efficient in introducing a new concept or idea, we felt it best to convene a large group of farmers in one room; not always the best idea if what you are introducing is, even slightly, contentious: The first expression of hostility spreads like wild-fire to the whole group and the next thing you find yourself (and the idea being introduced) facing a withering “attack” across all fronts. Those sorts of meetings seldom ended well!

Those tough encounters, while rather unnerving and unpleasant at the time, forced us to think a lot harder about how one can and should approach the matter of effecting positive change at farm-level.  Some formative ideas emerged from these examinations:

  • Farmers hold the most important “keys” to sustainability for the whole supply-chain
  • Every farm is different
  • Every farmer develops site-specific knowledge and solutions
  • Real change comes from the inside-out

These insights showed us that our approach itself had to first undergo fundamental change. Over the past eight years, Blue North has developed, refined and evolved its approach, always endeavouring to give practical expression to these formative insights. This journey has now culminated in SHERPA, an online management system designed to support farmers in their strategic journeys to strengthen the long-term resilience and viability of their businesses.

Where did the name Sherpa come from? We were inspired by the renowned Himalayan guides who make it possible for mountaineers to prevail in the face of the most challenging conditions imaginable, and to succeed in conquering the highest and most dangerous mountains in the world. But Sherpas never climb the mountain for the climber, it’s always the climber’s own quest, the Sherpas just providing the guidance, council and support as needed to ensure success. This thinking has come together in the logo and strap-line that is shortly to be released on-line:

In short, SHERPA is designed as a “bottom-up” management system that provides expert support and guidance to a business on its journey of developing and implementing a sustainability program, such that it is fully “owned” by the business and is relevant, reflective of the business’s “reality” and effective in delivering true sustainability outcomes for the business (and the supply-chains of which it forms part).

SHERPA is a cloud-based system comprised of a number of components and processes, integrated into an end-to-end sustainability management system:

We are currently putting the finishing touches to SHERPA and have started the process of migrating all the data-sets from the excel-based tools (that have served as precursors to the on-line platform) onto the SHERPA database. We have begun engaging with current and prospective clients to reveal the inner workings of SHERPA, and if you are interested to have a demonstration please feel free to make contact with us via info@bluenorth.co.za.

Harvesting ‘Knowledge’ with Podcasts

Have you come across the word ‘podcast’? There is a growing trend of people listening to podcasts, but if you are not among this trend you might be wondering, what exactly is a podcast and why should you bother?

A podcast is a digital audio file you can download from the internet. You can download a podcast to a computer, but most people download podcasts to their smartphones and listen to them “on the go”.

Podcasts are an easy way to gain knowledge and understanding about a specific subject area from passionate people who are experts in their field. And did I mention most podcasts are free…?!

So, what are podcasts about? There are literally thousands of topics, but broad categories include:

  • Business & Industry
  • News
  • Sport
  • Parenting, Kids and Family
  • Science & Medicine
  • Technology
  • Lifestyle & Health
  • Society & Culture
  • Politics
  • Religion
  • Comedy
  • Etc.

Whoever you are, there will be a podcast show for you!

Podcasts are produced by people who are passionate about a subject area. Podcasts episodes from the same person are normally grouped together as a show or series. Each show has a unique name and brand, like a TV series.

It is easy to find interesting, popular and trending shows. You just select the podcast category that interests you, and then the most popular shows will list first, or you can search, browse and explore to find a very specific show that appeals to you. Shows normally release a new episode or installment every week. This means that if you subscribe to a show, you will receive new installments automatically.

There are some great agriculture related shows, from regenerative agriculture, commodity specific farming, agri-marketing, agri-science, agri-investing, commodity markets, technologies, etc. If you are in an agri-supply chain, there will be an interesting podcast show for you.

The Regenerative Agriculture Podcast, hosted by John Kempf, is a great show to start with. Here are some of the show’s episode titles to whet your appetite:

  • Preventing nitrogen and phosphorus leaching.
  • Things to do when plants don’t respond to nutrient applications.
  • Why should we care about soil health?
  • Symbiotic relationships in ecology.
  • How insect pests identify unhealthy plants.

Now that you have a better understanding of what podcasts have to offer, you might be wondering, do I need to be tech-savvy to listen to a podcast? Absolutely not! Here’s an easy guide on how to access podcasts:

  1. Install the “Stitcher” app from iTunes App Store or Google Play (Android).
  2. Register on the Stitcher app.
  3. Browse shows and “star” your favorites to automatically download new episodes.
  4. Listen to shows through the Stitcher app on headphones, or even better, via Bluetooth over your car’s audio system.

Conservation Agriculture: A Focus on the Grains Industry

What is conservation agriculture? How is it important for both industry and individual farmers?

To answer these questions and better understand the importance of conservation agriculture within the grains industry, we spoke to Dr Hendrik Smith, the Conservation Agriculture Facilitator for Grain SA. 

What is conservation agriculture in the grains industry and why is it important?

Conservation Agriculture (CA) is an approach to managing agro-ecosystems for improved and sustained productivity, increased profits and food security while preserving and enhancing the resource base and the environment. CA is characterized by three linked principles, namely:

  1. Continuous minimum mechanical soil disturbance.
  2. Permanent organic soil cover.
  3. Diversification of crop species grown in sequences and/or associations.

CA principles are universally applicable to all agricultural landscapes and land uses with locally adapted practices. CA enhances biodiversity and natural biological processes above and below the ground surface. Soil interventions such as mechanical soil disturbance are reduced to an absolute minimum or avoided, and external inputs such as agrochemicals and plant nutrients of mineral or organic origin are applied optimally and in ways and quantities that do not interfere with, or disrupt, the biological processes.

CA facilitates good agronomy, such as timely operations, and improves overall land husbandry for rainfed and irrigated production. Complemented by other known good practices — including the use of quality seeds, and integrated pest, nutrient, weed and water management, etc. — CA is a base for sustainable agricultural production intensification. It opens increased options for integration of production sectors, such as crop-livestock integration and the integration of trees and pastures into agricultural landscapes.

Why has Grain SA decided to support a transition to conservation agriculture and what are the implications for the industry as well as for the individual farmers?

In South Africa, crop production systems based on intensive and continuous soil tillage have led to excessively high soil degradation rates in grain producing areas. This adds to the growing problems with profitability and poverty in some of the rural areas. If we have to offer farmers a better chance to survive on the farm, and if sustainable and economically viable agriculture is to be achieved, then the paradigms of agriculture production and management must be changed.

There is general agreement among key stakeholders in SA, that the reversal of environmental degradation processes, such as soil erosion, loss of biodiversity and climate change, as well growing problems with profitability and poverty, will be achieved through the adoption and implementation of CA. CA is seen as an ideal system for sustainable and climate-smart agricultural intensification, through which farmers can attain higher levels of productivity and profitability (i.e. or ‘green prosperity’) while improving soil health and the environment.

What Makes a Good Farmer?

What are the attributes of a really good farmer? Would they include a penchant for order and neatness? A single-minded focus on efficiency and yield maximization? A bullet-proof resolve in the face of risk? What about drive for expansion and scale or technical proficiency? While some or all of these may currently inform our rating of farmers, I want to propose some alternative attributes in response to this question. But before getting there, some context is needed.

One of the formative ideas, probably the most important one, that shaped our thinking when we started Blue North in 2011, and which fundamentally shapes what we do to this day, is understanding farmers as the key role-players in determining the sustainability of food supply-chains, and, by extrapolation, the sustainability of mankind as a whole.

Sound a bit grandiose? We think not: Farmers stand at the interface between the natural system and its inherent productive potential, and mankind’s dependence on the outputs of that system. We easily forget that dependence; we experience food, not as the product of our tilling, plowing, planting and tending, but as hygienic, wrapped and graded items only as far away, and requiring of effort, as a trip to the closest retail outlet.  In spite of the fact that the modern age has allowed the majority of people to live geographically disconnected from primary food production, our dependence on primary agricultural output remains obstinately steadfast and immutable.  We may live with the illusion of being unshackled from the drudgery and toil of farming, free to live in the “knowledge economy”, but it remains an illusion. As Wendell Berry says, “eating is an agricultural act”[1], and all we have done in effect, is outsource our food production to a few, very important people, farmers.

Two factors further magnify the importance of farmers: Firstly, farms, unlike factories, are non-uniform. No two farms are the same; their uniqueness a function of their particular soils, slopes, aspects, drainage, altitudes and micro-climates. This means farmers, unlike factory managers, have to be sensitive to, and learn to manage within, the tolerances of a very specific “place”. A critical coupling, therefore, exist between a farmer and the farm, resulting in the emergence of, often uncodified, site-specific knowledge, solutions and adaptations. The second magnifier is that agriculture represents the largest physical manifestation of negative anthropogenic impact on the planet – mankind’s antagonistic relationship with planet Earth is no more evident than in the vast scale of transformation of natural landscapes for agriculture.

This means that we cannot think about sustainability in general without deep consideration of agriculture, and we cannot consider “sustainable agriculture” without contemplating very fundamental changes to the way that we “do” agriculture. And the key actor at the center of this change is the farmer.

In short, there is a lot at stake and a lot rests on the shoulders of a very important but relatively small community of individuals. It is appropriate, therefore, to more deeply consider the question “what makes a good farmer?” in a bit more depth, and I want to propose, as a start, the following six attributes;

a. A good farmer is a systems thinker, able to perceive and understand the linkages between the farm’s productivity and the social and ecological dimensions of the farm; clear about what the farm depends upon and what its impacts are and how these need to be managed. Systems thinking also implies an understanding that the farm is not an isolated “island” but part of a larger integrated social and biophysical systems – the landscape or catchment – whose “health” is critical to the well-being of the farm, and vice versa. This demands that a farmer’s scope of thinking and management extends well beyond the legal boundaries of the farm.

b. A good farmer builds financial, social and natural capital. Warren Buffet’s patient approach to investing provides a useful analogy; the aim being to build capital to a point where one can live off the interest, necessitating a long-term view and avoiding eating into the capital base or putting it at risk. This stands in stark contrast to market speculation-based investing, high on adrenalin but fraught with risk (and poor performance measured over the long-term). Good farmers apply this thinking and approach not only to their financial capital, but to the management of the farm’s natural and social/human capital, understanding that short-term erosion of these capital stocks fundamentally weakens the farm, while consciously nurturing and growing them is essential to the farm’s productivity and viability in the long-term.

cA good farmer builds buffer capacity: Related to the above, this is about building in a “margin of safety” into the different aspects of the farm that collectively reduce its vulnerability to external shocks. In the current age, efficiency is often the ultimate measure of performance, and the building and maintaining of “buffers” can seem counterproductive, even wasteful. But good farmers understand how important buffer capacity is. In the financial dimension this is about maintaining sufficient levels of financial reserves to be able to continue as a going-concern through periods of low production, low prices, market closures etc. In the social dimension it’s about investment in the farm’s workforce beyond the menial, to those things that really build human potential, and which build the collective wisdom of the farm, in so doing endowing the farm with adaptive capacity – the ability to quickly perceive and effectively respond-to changing conditions.  In the ecological dimension it is about restoring and maintaining areas of natural diverse vegetation and biodiversity (such as biodiversity corridors, riparian buffer zones, diverse cover cropping etc.) even when at the “cost” of reduced areas for production. This sustains and strengthens key ecological processes (for example pollination, pest & disease suppression, soil conservation, flood suppression, nutrient cycling etc.) which reduces the farm’s sensitivity to environmental changes and shocks.

d. A good farmer is a master in delayed gratification: Good farmers play the “long game”, sacrificing short-term gain in favor of long-term stability and strength. Building required financial, social and natural capital as well as sufficient buffer capacity takes self-restraint and patience. Good farmers are also deeply attuned to what constitutes the natural pace of the farming system and are sensitive to anything that risks “forcing that pace” above a level where capital stocks risk being undermined. The use of fossil-fuel based agrochemicals and fertilizers is a case in point; while they provide a quick and convenient solution to a particular pest or nutrient deficiency in the short-term, injudicious use (forcing the pace) comes with the real risk of erosion of the natural and human capital of the farm. Just think of the long-term cost to farms of pest & disease resistance, water eutrophication, soil health decline and chronic illness in workers, for example.

e. A good farmer is a great observer/listener, looking out for and sensitive to feedback from across the system. Typically, financial and operational reporting is available, and most farmers rely on these feedback-loops to assess and manage progress. Good farmers know, however, that this information speaks for only part of the system – providing an incomplete and potentially distorted picture. Sensing the state of natural and social/human capital, the well-being of flows from these stocks and the farm’s impacts on them, the suitability of buffers for each etc. requires a step well beyond financial and operational reporting. It calls for a more nuanced approach of greater sensitivity. It requires time with employees building relationships and reliable, open and trusted communication channels. It requires regular time in-field, becoming sufficiently attuned and sensitive to subtle shifts in the farm’s ecological processes, interactions and dynamics. It also speaks to concerted efforts to build performance metrics and reporting that show the financial, social and ecological in an integrated and holistic way, not as disconnected components.

f. A good farmer is an innovator par excellence, able to take on board feedback, and to develop, test and implement the actions necessary to maintain the farm’s ongoing well-being. This attribute means no tolerance for complacency while demanding tolerance for the unavoidable discomfort associated with ongoing change. This capacity to drive ongoing improvement and perpetual learning is essential within a context of accelerating change and pressures from within the social, political and environmental spheres within which farms exist. Innovation equates to adaptation, and farmers have to be masters at managing adaptation in order for their farms to successfully evolve and survive in the long-term.

Ultimately, and in summary, a good farmer is a steward, a custodian of a more complex system then many of us dare to contemplate, yet one that we are utterly dependent upon. They deserve our keen interest, sympathetic support and deep respect.

Please let us know what you think of these and if you feel any important attributes have been missed. It’s an important conversation for us to be having.

Case Study: Reducing Carbon Emissions on Farms with Improved Water Management

For water-scarce countries like South Africa, irrigation is critical, and with the majority of electricity being carbon emission intense, irrigation is an important contributor to a farm’s carbon footprint. Indeed, according to Confronting Climate Change industry benchmark reports, electricity consumption for irrigation is the largest source of farm-level carbon emissions. Therefore, improving water management on farms not only has the potential to save water, but also helps reduce operating costs and carbon emissions.

To help farmers access these savings, Koos Bouwer, of Koos Bouwer Consulting, provides his insight into the opportunities for savings obtained during an assessment of irrigation pumping systems on fruit farms. The full case study is available here:  Koos Bouwer Case Study

Carbon Tax

Review of the 2017 Second Carbon Tax Draft Bill

The Second Draft Carbon Tax Bill (National Treasury, 2017) was published on 15 December 2017 following an extensive consultative process around the First Carbon Tax Bill (National Treasury, 2015). It is expected that the Revised Second Draft Carbon Tax Bill will be tabled in parliament in mid-2018, following the due consultative processes.

Whilst the core principles of the tax have remained the same, there have been significant changes to the structure of the bill. Although the agriculture, fisheries, forestry and waste sectors will be exempt from the first phase of the tax, during the second phase these sectors could be included. According to economists at the Western Cape Department of Agriculture, what this implies for the agricultural sector is that despite not being taxed directly, the sector could see significant indirect impacts, such as a rise in the price of key inputs such as electricity, fertilizers and pesticides (Partridge et al, 2015).

According to the Western Cape Department of Agriculture, in order for the sector to react accordingly to the implications of the Second Draft Carbon Tax Bill, it is necessary that the sector fully understands the implications of the tax, so as to be able to lobby for outcomes which will best aid the sector going forward. To aid this objective, the Western Cape Department of Agriculture has prepared a brief (FINAL Review of the Second Draft Carbon Tax Bill May 2018) providing a review of the 2017 Second Carbon Tax Bill. This review outlines some of the key issues in relation to the First Carbon Tax Bill and how these have been addressed in the Second Draft Carbon Tax Bill.

Understanding agricultural, natural resource management and rural development interventions.

Blue North is increasingly involved in undertaking various types of program and project evaluations within the agricultural, natural resource management and rural development space. But just where does the need for understanding project impact and performance stem from?

Although many programs are obliged to undertake evaluations at different stages of project design, implementation and upon termination, evaluation is driven by a real need to understand and improve a certain situation. Evaluations are carried out to judge the worth, merit or quality of some object (termed the evaluand e.g. a project, a program or even a change in practice or policy). The evaluation is typically conducted using criteria such as relevance, effectiveness, efficiency, sustainability, and impact. It is important to note that evaluation approaches do not only deal with understanding the overall impact of a project. Different types of evaluations can serve different purposes in the project life cycle, for example design, implementation, economic and mid-term evaluations. Important benefits of project evaluation are firstly, that it provides accountability, and secondly, that it serves as an important basis for improvement, learning, and the provision of recommendations that can guide projects.

The fields of agriculture, natural resource management and rural development are inherently complex, effected by multiple processes and actors at different scales. Understanding and assessing programs and projects within these fields thus demands an approach that can deal with complexity. At Blue North, we find it useful to consider these interlinked areas as a complex system. As an illustration of this thinking, consider a food system, which is woven together as a supply chain that operates within broader economic, biophysical, and socio-political contexts. Such a system is both complex and adaptive, composed of many heterogeneous pieces whose interactions drive system behaviour in ways that cannot easily be understood from considering the components separately. Importantly, complex systems, whether they are social, physical, or biological, tend to share a set of specific properties. Consideration of these properties and their implications from various scientific and policy perspectives has yielded important insights into system behaviour.

When we are evaluating projects and programs encompassing the food system, given its inherent complexity, we therefore need to make sure that we develop a deep understanding of the system parts as well as the emergent properties of the system itself. For example, this could include environmental disturbances caused by land owners’ decisions about management of climate, land, and water resources in addition to various socio-economic effects mediated by policy processes within the rural landscape, such as income, wealth, and distributional equity, quality of life, and worker health and well-being.

Conceptualizing food systems as complex systems therefore has a strong bearing on our thinking, both during the design of our research approach and methodology for the evaluation of specific projects, and during analysis of project impact or performance. In particular, we have used this approach to frame our thinking in the evaluation of projects and programs in the rural landscape. This includes the assessment of various projects and programs with different objectives such as the improvement of small scale farmers’ livelihoods, the sustainable transformation of the rural landscape and sustainable resource management.

Why is climate neutrality important?

Driven by the emission of greenhouse gases (GHGs) through anthropogenic (human) activities, the planet’s climate is changing. To limit the impact of a changing climate on the planet’s future, global GHG emissions need to be reduced as much as possible. This is a global challenge, to which we all need to contribute! Carbon, or climate – neutrality implies that, through a combination of various strategies, the carbon footprint across a product’s full value chain is reduced to zero.

How can I reduce my carbon footprint to zero?

Through your participation in the Confronting Climate Change (CCC) Initiative, your wine or fruit farm may have already calculated its carbon footprint. Across your product’s value chain, you probably have a good idea of the key drivers of your carbon footprint, whether it is caused by agrochemicals, fuel consumption, energy use, processing, packaging, or freight.  Through the implementation of new technology and operational strategies, the first step is to reduce your carbon footprint as far as possible. Together with various environmental benefits, this can have many financial advantages. Inevitably, there will be elements of your product’s carbon footprint that are incredibly difficult and costly to eliminate.
From here, your best option to reduce your carbon footprint to zero is to offset unavoidable emissions through the purchase of carbon credits. Confronting Climate Change (CCC ) has partnered with Climate Neutral Group to facilitate the purchase of certified carbon credits.

How can your wine estate or fruit farm make its value chain climate neutral?  What do I get?

Climate Neutral Group, an international carbon management firm with an office in Cape Town, has worked with hundreds of organisations to measure, reduce and offset their carbon emissions. Clients in South Africa include Sanlam, Canon, Webber Wentzel, the Two Oceans Aquarium, Sun International and many more. Climate Neutral Group has also helped to set up a number of carbon offsetting projects in South Africa, Southern Africa, and elsewhere in the world. The carbon credits associated with these projects are certified through the Verified Carbon Standard (VCS) or the Gold Standard.  In addition to generating carbon credits, these projects are community-orientated, creating value for underprivileged communities. Purchasing carbon credits presents an opportunity to be part of the solution, both environmentally and socially! Provided that your product’s carbon footprint has been properly calculated, reduced where possible, and neutralised through the purchase of certified carbon credits, your climate neutral journey provides you with an opportunity to tell a great and inspiring story.  More and more companies, particularly in European export markets, are concerned with the environmental impacts associated with a product’s entire value chain. We believe that your achievement of climate neutrality is a valuable story that should be heard.

If your wine estate/fruit farm is working hard to reduce its impact on the climate and wants to make its wines/fruit climate neutral, then the “Climate Neutral Guaranteed” standard by Climate Neutral Group is something to consider. Gaining momentum across Europe’s food and beverages sector, this logo recognises that the contributions of your efforts towards climate neutrality have been meaningful, environmentally and socially.
The logo furthermore ensures that the steps you have undertaken towards climate neutral operations have been tested against strict international criteria. The Climate Neutral Guaranteed standard finally helps you – efficiently and clearly – communicate your climate leadership role to consumers, suppliers, and other stakeholders. This is critical in fostering a new generation of socially, environmentally, and economically sustainable businesses.

What is the required investment?

Depending on the size of your product’s carbon footprint and the choice of carbon credits (the price of carbon credits varies across offsetting projects), your carbon footprint can be offset from as little as R0.10 per 750 mL bottle of wine or 3kg of fruit. Should you wish to display the climate neutral logo on your wine bottles, additional auditing costs apply.

Science Based Climate Targets

Calculating and understanding your carbon footprint has become generally accepted practice.  Organisations use carbon footprinting to identify greenhouse gas hotspots, understand the use of expensive inputs like diesel, electricity and fertilisers and to communicate their sustainability credentials.

Once you know and understand your carbon footprint you can set targets to reduce it.  Unfortunately few businesses set clear carbon reduction targets, and the few that do often choose arbitrary targets like “reduce electricity use by 20%”.  With the effects of climate change becoming a reality, consumers are rightly asking if “reducing electricity by 20%” is enough to slow down and eventually stop climate change.  This is where science based climate targets come in.

In 2015 the Paris Climate Agreement was negotiate by 196 countries and to date 174 countries have become party to it[i].  This agreement aims to keep the global temperature rise this century “well below 2 degrees Celsius” compared to pre-industrial levels.  This ‘hard’ target makes it easy to determine science based carbon budgets to achieve this.  Broadly speaking the 2 degrees Celsius target means we have to ween ourselves of fossil based inputs by 2050 (the latest research shows even this may be too little too late, but that is a discussion for another time).

What is a science-based climate target?

A carbon target is defined as ‘science based’ if it is in line with the level of decarbonisation required to keep global temperature increase below 2 degrees Celsius compared to pre-industrial temperatures.[ii] .

A science-based target thus defines a trajectory to move out of fossil fuel based inputs by 2050. Targets can be described as “weak” when not science based, and “strong” when they are.

An example of a how “strong” science based climate targets can and should influence policy is France’s decision to ban all petrol and diesel vehicles by 2040 and to no longer use coal to produce electricity after 2022.[iii]

As society increasingly feels the ‘bite’ of climate change, and its bigger brother, ‘abrupt climate change’, so the demand that businesses and their associated supply chains set meaningful and impactful carbon reduction targets is gaining momentum.

It is important to understand that science-based climate targets are very ambitious, long term in nature and will take businesses out of their comfort zones.  Imagine fossil-fuel free logistics connecting your business to your suppliers and markets.  This is the new reality we have to create for ourselves if catastrophic climate change is to be effectively avoided.

Adopting science-based targets puts your business and supply chain at the forefront of carbon management and reduction.

Who ensures the credibility of science based targets?

The Science Based Targets Initiative ( http://sciencebasedtargets.org/ ) is a collaboration between the Carbon Disclosure Project CDP, the World Resources Institute (WRI), the World Wide Fund for Nature (WWF) and the United Nations Global Compact (UNGC).  This initiative allows organisations to[iv]:

Step 1: Submit a letter of commitment.

Step 2: Develop a target.

Step 3: Submit the target for validation.

Step 4: Announce the target.


Which agri and retail businesses are perusing science based carbon targets in South Africa?

The bad news is not many companies at the moment.  The good news is you can become a leader in this regard!  Currently four South African retail and/or agriculture companies have signed up with the Science Based Targets Initiative.  They are[v]:

  • Pick ‘n Pay;
  • Tiger Brands;
  • Tongaat Hulett; and
  • Woolworths

Even though the companies above have committed to science-based targets, they have not as yet set any targets with the Science Based Target Initiative

Internationally, Marks & Spencer, Tesco and Wal-Mart Stores have gone a step further and set science based climate targets with the initiative.

So there remains a long way to go but the signs are positive that companies are beginning to understand that their targets need to move from “weak” to “strong” if they are to make any meaningful contributions to the de-carbonisation of our economic systems. The emergence of the concept of science-based targets and the formation of the Science Based Targets Initiative are important developments to both challenge and support businesses and supply-chains in this regard.

Understanding and addressing the carbon emission hotspots within your supply chain.

To effectively realise and respond to the opportunities and challenges posed by climate change the Confronting Climate Change (CCC) Project was started in 2009 as a strategic cross-industry initiative aimed at supporting the South African fruit and wine sectors’ efforts. Besides provision of a freely available on-line carbon emissions calculator, the CCC initiative promotes technical training supporting its adoption and use and has actively engaged with the retailers and importers to secure their support for the project. The results are accepted and feed into existing retailer sustainability requirements. This helps to avoid duplication of carbon footprinting systems. Farms, packhouses, wineries and other entities across the supply-chain are enabled to undertake accurate measurement of the energy-use and carbon-emissions intensity of their respective business activities. Such measurement is generally accepted as a prerequisite for the effective management towards greater resource-use efficiency, reduced emissions and the long-term sustainability of business activities and operations. The management principle of “you can’t manage what you don’t measure” applies.

Farm hotspots

The electricity consumption for the pumping of water is the largest source of farm-level carbon emissions since South African grid supplied electricity is predominantly coal based, and therefore carbon emissions intensive both in production and use. The most significant factors determining the energy requirements being the irrigation intensity of the crop and the pumping “head” of the farm.

The second biggest emitter at farm level is the usage of synthetic nitrogen-based fertilizers. As the production of all synthetic fertilisers is energy intensive and in South Africa, the energy is predominately fossil-fuel based, making these inputs carbon emissions intensive.  On the use side, the inefficient or over application of synthetic nitrogen fertilizers results in large amounts of nitrous oxide (N2O) emissions, a very powerful greenhouse gas: once emitted to the atmosphere, one ton of nitrous oxide is equivalent to 300 tons of carbon dioxide (CO2). In addition, the prices of these inputs will continue to rise as the fuel prices go up, increasing the risk of increased input costs at the farm level. The more natural products are often multi-beneficial in that they increase soil health which does not only lessen the requirement of synthetic additions, but also improves water retention and productivity. Commodity groups that require more intensive fertilizer programmes will have higher carbon emissions than those that utilize more conservative and natural soil enhancement practices.

Diesel usage is the third largest emissions-source and relates to the usage of a variety of vehicles and equipment for spraying, harvesting, soil preparation, transportation and other farming activities.

Packhouse hotspots

Most of emissions at packhouse level are related to packaging material. The pome fruit and citrus (hard) packhouse emissions are the lowest of all fruit types, pointing to the less intense packaging requirements of these “harder” fruit types.

Winery hotspots

Winery hotspots relate to the use electricity for cooling and virgin packaging material, particularly glass and corrugated cardboard boxes. The use of wooden barrels also plays a significant role in the winery emissions as these barrels are often imported.

These activities form most of the carbon emissions throughout the supply-chain and should therefore be targeted as a priority area for improved efficiencies and alternative product usage.

How can I reduce or manage my carbon emissions?

  1. Start to measure your carbon related inputs.
  2. Enter your data in the CCC carbon footprint calculator.
  3. Read and analyse the detailed carbon emissions report provided once you have entered all your data correctly.
  • Look at your carbon emissions figure and compare it with the benchmark given in the report for your commodity and your region.
  • Look at the individual inputs to your business and learn from the report what percentage they contribute to your total carbon emissions. Start to manage those that result in the highest emissions in your business.
