We Can't Do It Ourselves

SUBHEAD: Mostly we're locked into unsustainability by being connected to the grid, driving cars and eating meat.

How to live a more sustainable life? This question generates a lot of debate that is focused on what individuals can do in order to address problems like climate change.

For example, people are encouraged to shop locally, to buy organic food, to install home insulation, or to cycle more often.

But how effective is individual action when it is systemic social change that is needed? Individuals do make choices, but these are facilitated and constrained by the society in which they live.

Therefore, it may be more useful to question the system that requires many of us to travel and consume energy as we do.

Climate Change Policies

Policies to address climate change and other environmental problems are threefold: decarbonisation policies (encouraging renewable energy sources, electric cars, heat pumps), energy efficiency policies (decreasing energy input/output ratio of appliances, vehicles, buildings), and behavioural change policies (encouraging people to consume and behave more sustainably, for instance by adopting the technologies promoted by the two other policies).

The first two strategies aim to make existing patterns of consumption less resource-intensive through technical innovation alone. These policies ignore related processes of social change, which perhaps explains why they have not led to a significant decrease in energy demand or CO2-emissions.

Advances in energy efficiency have not resulted in lower energy demand, because they don’t address new and more resource-intensive consumption patterns that often emerge from more energy efficient technologies. [1] [2]

Likewise, renewable energy sources have not led to a decarbonisation of the energy infrastructure, because (total and per capita) energy demand is increasing faster than renewable energy sources are added. [3]

Consequently, the only way to reduce greenhouse gas emissions is to focus more on social change. Energy efficiency and decarbonisation policies need to be combined with “social innovation” if we want energy use and carbon emissions to go down.

This is where behavioural change policies come in. The third pillar of climate change policy tries to steer consumer choices and behaviours in a more sustainable direction.

Behavioural Change Policies

Instruments and policy packages designed to achieve behaviour change vary greatly, but most can be categorised either as “carrots, sticks, or sermons”. [4]

They can be economic incentives (such as grants for “green” products, energy taxes, soft loans), standards and regulations (such as building codes or vehicle emission standards), or the provisioning of information (more detailed energy bills, smart meters, awareness campaigns).

All these policy instruments are focused on what are thought to be the determinants of individual behaviours. [5-9] They assume that either individuals take rational decisions based on product price and information (the homo economicus model), or that behaviours are the outcomes of beliefs, attitudes and values (various value-belief models).

According to these dominant social theories, people engage in pro-environmental behaviour for self-interested reasons (because it is enjoyable or saves money), or for normative reasons (because they think it’s the right thing to do).

However, many pro-environmental actions involve a conflict between self-interested and normative reasons. Pro-environmental behaviour is often considered to be less profitable, less pleasurable, and/or more time-consuming.

Consequently, people need to make an effort to benefit the environment, and this is why, according to behavioural change researchers, pro-environmental values and attitudes are not necessarily matched by individuals’ behaviours – a phenomenon they call the “value-action gap”.

To close this gap, two strategies are proposed.

The first is to make normative goals more compatible with self-interested goals, either by decreasing the costs of pro-environmental actions, or by increasing the costs of harmful actions.

The second strategy is to strengthen normative goals, in the hope that people will engage in pro-environmental behaviour even if it is more expensive or effortful. This is usually pursued through awareness campaigns.

Individual Choice

However, the results of behavioural change policies have been disappointing so far. Two decades of climate-change related awareness campaigns have not decreased energy demand and carbon emissions in a significant way. The reason for this limited success is that existing attempts to change behaviour rest on a very narrow view of the social world. [10]

Behavioural change policies are based on the widespread agreement that what people do is in essence a matter of individual choice. [4] [11] [12] For example, whether people pick one mode of travel or another, is positioned as a matter of personal preference. [4] It follows that agency (the power to change) and responsibility for energy demand, consumption, and climate change are ultimately thought to lie within individual persons.

It is this concept of choice that lies behind strategies of intervention (persuasion, pricing, advice). Given better information or more appropriate incentives, “badly behaving” individuals are expected to change their minds and choose to adopt pro-environmental behaviours. [11]

Obviously, individuals do make choices about what they do and some of these are based on values and attitudes. For example, some people don’t eat meat, while others don’t drive cars, and still others live entirely off-the-grid.

However, the fact that most people do eat meat, do drive cars, and are connected to the electric grid is not simply an isolated matter of choice. Individuals do not exist in a vacuum. What people do is also conditioned, facilitated and constrained by societal norms, political institutions, public policies, infrastructures, technologies, markets and culture. [10] [13] [14]

The Limits of Individual Choice

As individuals, we may have degrees of choice, but our autonomy is always limited. [13] [14]

For example, we can buy a more energy efficient car, but we can’t provide our own cycling infrastructure, or make car drivers respect cyclists.

The Dutch and the Danish cycle a lot more than people in other industrialised nations, but that’s not because they are more environmentally conscious.

Rather, they cycle in part because there’s an excellent infrastructure of dedicated cycle lanes and parking spaces, because it is socially acceptable to be seen on a bike, even in office wear, and because car drivers have the skills and culture to deal with cyclists.

For example, Dutch drivers are taught that when they get out of the car, they should reach for the door handle using their right hand – forcing them to turn around so that they can see if there is a cyclist coming from behind.

Furthermore, in case of an accident between a car driver and a cyclist, the car driver is always considered responsible, even if the cyclist made a mistake.

Obviously, an individual in the UK or the US can decide to go cycling without this supporting infrastructure, culture, and legal framework, but it is less likely that large numbers of people will follow their example.

People in industrialised countries are often locked into unsustainable lifestyles, whether they like it or not. Without a smartphone and always-on internet, for example, it is becoming difficult to take part in modern society, as more and more daily chores depend on these technologies.

Once the connected smartphone is established as a ‘necessity’, an individual can still choose to buy an energy efficient device, but he or she can’t do anything about the fact that it will probably stop working after three years, and that it cannot be repaired.

Neither do have individuals the power to change the ever increasing bit rates on the internet, which systematically add to the energy use in data centers and network infrastructure because content providers keep “innovating”. [15]

An individual can try to consume as little as possible, but he or she shouldn’t expect too much help because the dominant economic system requires growth in order to survive.

Blaming Each Other

In sum, individuals can make pro-environmental choices based on attitudes and values, and they may inspire others to do the same, but there are so many other things involved that focusing on changing individual “behaviour” seems to miss the point. [4]

Trying to persuade people to live sustainably through individual behaviour change programmes will not address the larger and more significant structures and ideas that facilitate and limit their options.

In fact, by placing responsibility – and guilt – squarely on the individuals, attention is deflected away from the many institutions involved in structuring possible courses of action, and in making some very much more likely than others. [11]

The discourse of sustainable “behaviour” holds consumers collectively responsible for political and economic decisions, rather than politicians and economic actors themselves.

This makes pro-environmental “behaviour” policies rather divisive – it is the other individuals (for example meat eaters or car drivers) who are at fault for failing to consume or behave in line with particular values, rather than politicians, institutions and providers which enable unsustainable food and transport systems to develop and thrive.

As this example makes clear, individual behaviour change is not just a theoretical position, it is also a political position. Focusing on individual responsibility is in line with neoliberalism and often serves to suppress a systemic critique of political, economic and tech

Beyond Individual Behaviour

If significant societal transformations are required, it makes more sense to decenter individuals from the analysis and look at the whole picture.

Other approaches in social theory suggest that rather than being the expression of an individual’s values and attitudes, individual behaviour is in fact the observable expression of the social world, including socially shared tastes and meanings, knowledge and skills, and technology, infrastructure and institutions.

As such, behaviour is just the “tip of the iceberg”, and the effects of intervening in behaviour are limited accordingly.

A much better target for sustainability is the socially embedded underpinning of behaviour – the larger part of the iceberg that is under water. [13]

This might entail focusing not on individuals and choices but on the social organisation of everyday practices such as cooking, washing, shopping, or playing sports. How people perform these practices depends not only on individual choice, but also on the material, social and cultural context. [10] [13]

If social practices are taken to be the core units of analysis, rather than the individuals who perform them, it becomes possible to analyse and steer social change in a much more meaningful way. [10] [13]

By shifting the focus away from individual choice, it becomes clear that individual behaviour change policies only represent incremental, minimal or marginal shifts at the level of a practice. At the same time, it reveals the extent to which state and other actors configure daily life.

For example, the idea that a car equals personal freedom is a recurrent theme in car advertisements, which are much more numerous than campaigns to promote cycling.

And because different modes of transport compete for the same roadspace, it is governments and local authorities that decide which forms get priority depending on the infrastructures they build.

When the focus is on practices, the so-called “value-action gap” can no longer be interpreted as evidence of individual ethical shortcomings or individual inertia. Rather, the gap between people’s attitudes and their “behaviour” is due to systemic issues: individuals live in a society that makes many pro-environmental arrangements rather unlikely.

The New Normal

In conclusion, although individual behavioural change policies purport to address social and not just technological change, they do so in a very limited way.

As a result, they have exactly the same shortcomings as the other strategies, which are focused on efficiency and innovation. [2] Like energy efficiency and decarbonisation policies, behaviour change policies don’t challenge unsustainable social conventions or infrastructures.

They don’t consider wider-ranging system level changes which would radically transform the way we live – and that could potentially achieve much more significant reductions in energy use and greenhouse gas emissions.

For example, recycling garbage does not question the production of waste in the first place, and even legitimizes it. By diverting attention away from systemic issues that drive energy demand, behavioural change policies frequently reinforce the status quo. [11-13]

In contrast to policies aimed at individuals, policies that frame sustainability as a systemic, institutional challenge can bring about the many forms of innovation that are needed to address problems like climate change.

Relevant societal innovation is that in which contemporary rules of the game are eroded, in which the status quo is called into question, and in which more sustainable practices take hold across all domains of daily life. [11]

Social change is about transforming what counts as “normal” – as in smoke-free pubs or wearing seat belts. We only need to look back a few decades to see that practices are constantly and often radically changing. A systemic approach to sustainability encourages us to imagine what the “new normal” of everyday sustainability might look like. [13]

A sustainability policy that focuses on systemic issues reframes the question from “how do we change individuals’ behaviours so that they are more sustainable?” to “how do we change the way society works?”. This leads to very different kinds of interventions.

Addressing the sociotechnical underpinnings of “behaviour” involves attempting to create new infrastructures and institutions that facilitate sustainable lifestyles, attempting to shift cultural conventions that underpin different activities, and attempting to encourage new competences that are required to perform new ways of doing things. As a result of these changes, what we think of as individual “behaviours” will also change.

Pedal Power Farming

SUBHEAD: Two articles on the development of pedal power farm tractors by Farm Hack.
 
Second Prototype

By Staff on 15 November 2014 for No Tech Magazine -
(http://www.notechmagazine.com/2014/11/pedal-powered-farming.html)


Image above: Field test of second prototype of peddle powered farm tractor. From original article.

The Culticycle is a pedal powered tractor that can cultivate, seed, spray, or pull gear for most low horsepower tasks. We talked about the first prototype almost two years ago. A new version has now been released, built around a modular tractor frame. Tim Cooke explains us how it’s built and how it works: 
“The math behind the idea is nothing more than observing that a lot of the work a tractor does – shallow cultivation, seeding, flame weeding – requires very little of its available horsepower; and since these jobs are best done between 3 and 5 mph, a bike can be geared down low enough that a human can produce the necessary horsepower.

Take the cranks, seat, and handlebars from a bike and center them in a 4-wheel, lightweight, modular tractor frame: the obvious frame material is telestrut. For the front end use 20″ bike wheels and forks. You need about a foot of clearance but you want a low center of gravity and as much traction as possible: get 25 x 8 ATV tires for the rear, ideally with aluminum rims.”

“Assume you’ll pedal at 60 rpm and use a gear ratio of about 2.2 on the cranks to 3 on the differential. Now you have 25/12 x π for one revolution of the tire, x 22/30 gear ratio, x 60 rpm, x 60 minutes, divided by 5280 feet per mile = 3.3 mph. Pedal at 70 rpm and you’re at 3.8 mph. Meanwhile you’re not hunched and twisted and causing joint damage, you’re getting aerobic exercise.

And if your farm is bigger with tighter time constraints, have 2 or 3 of these machines set up specifically for those 2 or 3 row spacings that you use the most, and put the interns or volunteers on them. For instance one with a basket weeder, one with sweeps, one with finger weeders. Or fatten the front tires and throw a 12 foot aluminum ladder across the chassis and hang those big plastic harvest bins from each end, out over the beds, for lettuce harvesting: you could put 100 pounds on each end of the ladder.”

First Prototype

Video above: Field test of first prototype of peddle powered farm tractor. From (https://youtu.be/C4u87VhYFV0).

“The Culticycle is a pedal powered tractor that can cultivate, seed, spray, or pull gear for most low horsepower tasks. Small tractors do many jobs very well and very fast, but also consume fuel, compact soil, cost a lot, and cause physical damage to the operator -– mainly spine and joint problems. Many of their jobs could be done, slower but better, by human pedal power.
This prototype consists of:
  • the front ends of 2 bikes welded together at 42” on center;
  • a lawn tractor differential mounted in a unistrut rectangle for a rear end , with 3/4″ round axles and 20” ATV tires;
  • a bike frame welded above the rear end with motorcycle sprocket and chain driving the differential (a springloaded idler tensions the chain);
  • a belly mount lift to hold cultivators, seeders, etc.;
  • a bike handlebar, separate from the bike frame and joined to the front end, steering the front wheels.
The materials are rebar, unistrut, landscape rake tines, and parts from bikes, an ATV, and a lawn tractor. It attempts to show that human pedal power can do some jobs of small tractors, albeit in twice the time, and that the design can be simple enough that no extra weight is needed for traction. The effort required is similar to climbing a 10 degree slope on a seventies Schwinn 3 speed. This prototype was built for testing: a more easily buildable version is in the works.”



Some Background

By Stall on 3 March 2015 for Green Horns -
(https://thegreenhorns.wordpress.com/2015/03/31/pedal-power-farm-hack-report-from-the-feild/)

An ace team of farmers, fabricators, engineers, and pedal-powered truckers gathered at Metro Pedal Power in Somerville, MA for a weekend build event. What project would bring such an intriguing group of individuals together? Only the culticycle, a pedal-powered cultivating tractor designed by Tim Cooke, that uses human brawn and bicycle brains to replace fossil fuel powered tractors for lightweight field cultivation. Culticycle video here!

First, a quick introduction of our weekend hosts. Metro Pedal Power is a pedal-powered hauling business in the Boston area, replacing box trucks with custom-built freight trikes to haul last-mile inter-city freight such as compost, recycling and CSA shares. They hope to reduce urban congestion and traffic, improve human wellbeing, and encourage others to see the appropriateness of pedal power in the urban environment.

Wenzday and Eric from MPP generously hosted the build event at their fully outfitted shop in Somerville, without which the event would have been wholly impossible and a lot less comfortable. Many thanks to them and the rest of their team for hosting, convening and offering their fabrication skills.

The goal of the pedal power hack was several fold. We wanted to showcase an already built culticycle for those who had never laid eyes on it before, and bring minds together to brainstorm improvements as Tim moves forward in his development of the tool.

Several attendees also were in the process of building their own culticycle, or had already done so, so we additionally hoped to build some replacement components and share knowledge of the build process that we could take home with us.

Additionally, we wanted to document the tool more thoroughly, specifically in CAD design format to be shared freely on the Farm Hack Tools platform. We also wanted to use this opportunity to shoot video and take photos to capture the Farm Hack collaborative design and build process as it was happening.

With those goals in mind, we set forth Saturday morning by working together to assemble a pre-built culticycle, so that everyone would have a chance to look over the design and get a sense of how the pieces fit together. We then split into several teams.

Team 1 started from scratch with steel stock, cutting and grinding the structural pieces of the chassis – using Tim’s documentation to guide their effort but also improving upon the design as they went.

Team 2 worked on “Culti 2,” a culticycle which was about halfway completed but still needed steering linkages and the parallel lift which raises and lowers the tools.

Team 3 began to rebuild the “belly mount,” or toolbar, which is attached underneath the culticycle and which the weed killing tools are clamped to. This new and improved belly mount will be delivered to Hawthorne Valley Farm and installed on their culticycle, replacing the older, less robust model which was a part of the earlier culticycle design iteration.

For a day and a half, the shop buzzed with activity as folks dropped in to observe the process or get their hands dirty cutting, grinding, and welding. Lu Yoder brought along his pedal powered grain grinder, grinding wheat and making bread on Saturday and grinding corn for his brother Chris’s CSA Sunday.

By midday Sunday, we had made significant progress on both the second and third culticycles, finished a pile of DIY, cheaply made star hoes, nearly completed the belly mount, and made many small modifications and improvements to the Culticycle.

Farm Hack supports an approach to tool design and innovation that is built on principles of resilience. Instead of the top-down approach to tool development put forward by corporate agribusiness, the event this weekend prioritized local manufacturing, easily repairable and modifiable tool design, and collaborative and iterative research and development. For the better part of the last decade, Tim Cook has spent countless hours in his basement shop designing, tinkering, and building this machine from scratch.

This is a familiar model: an isolated innovator who is the focused, driving force behind a revolutionary tool design. The community of support which showed up this weekend to pitch in, cut, weld, prototype, and offer their design feedback and support are a vital part of this process of resilient design.

As we concluded the weekend-long build sprint, the conversation turned to next steps for the Culticycle and for Farm Hack, both community-driven efforts to re–imagine the landscape of our collective farming future. Keep an eye out for upcoming opportunities to be involved with both, including another eastern Massachusetts culticycle build in the next weeks, a Farm Hack event at the Draft Animal Power Field Days in Cummington, MA this September, and a late Fall event at Lu Yoder’s place.

And if you’re inspired by this Massachusetts flurry of activity, keep in mind that Farm Hack is made up of the collective efforts and contributions of all of us.
