Monitoring Water Banks with Telemetrics

Longstanding droughts across South Australia are forcing farmers to rethink the moisture in the soil they once regarded as their inalienable right. Trend monitoring is an essential input to applying pesticides and fertilisers in balanced ratios. Soil moisture sensors are transmitting data to central points for onward processing on a cloud, and this is making a positive difference to agricultural output.

Peter Buss, co-founder of Sentek Technology calls ground moisture a water bank and manufactures ground sensors to interrogate it. His hometown of Adelaide is in one of the driest states in Australia. This makes monitoring soil water even more critical, if agriculture is to continue. Sentek has been helping farmers deliver optimum amounts of water since 1992.

The analogy of a water bank is interesting. Agriculturists must ?bank? water for less-than-rainy days instead of squeezing the last drop. They need a stream of online data and a safe place somewhere in the cloud to curate it. Sentek is in the lead in places as remote as Peru?s Atacamba desert and the mountains of Mongolia, where it supports sustainable floriculture, forestry, horticulture, pastures, row crops and viticulture through precise delivery of scarce water.

This relies on precision measurement using a variety of drill and drop probes with sensors fixed at 4? / 10cm increments along multiples of 12? / 30cm up to 4 times. These probe soil moisture, soil temperature and soil salinity, and are readily re-positioned to other locations as crops rotate.

Peter Buss is convinced that measurement is a means to the end and only the beginning. ?Too often, growers start watering when plants don’t really need it, wasting water, energy, and labour. By monitoring that need accurately, that water can be saved until later when the plant really needs it.? He goes on to add that the crop is the ultimate sensor, and that ?we should ask the plant what it needs?.

This takes the debate a stage further. Water wise farmers should plant water-wise crops, not try to close the stable door after the horse has bolted and dry years return. The South Australia government thinks the answer also lies in correct farm dam management. It wants farmers to build ones that allow sufficient water to bypass in order to sustain the natural environment too.

There is more to water management than squeezing the last drop. Soil moisture goes beyond measuring for profit. It is about farming sustainably using data from sensors to guide us. ecoVaro is ahead of the curve as we explore imaginative ways to exploit the data these provide for the common good of all.

Energy Cooperation Mechanisms in the EU

While the original mission of the European Union was to bring countries together to prevent future wars, this has spun out into a variety of other cooperative mechanisms its founders may never have dreamed of. Take energy for example, where the European Energy Directive puts energy cooperation mechanisms in place to help member states achieve the collective goal.

This inter-connectivity is essential because countries have different opportunities. For example, some may easily meet their renewable targets with an abundance of suitable rivers, while others may have a more regular supply of sunshine. To capitalise on these opportunities the EU created an internal energy market to make it easier for countries to work together and achieve their goals in cost-effective ways. The three major mechanisms are

  • Joint Projects
  • Statistical Transfers
  • Joint Support Schemes

Joint Projects

The simplest form is where two member states co-fund a power generation, heating or cooling scheme and share the benefits. This could be anything from a hydro project on their common border to co-developing bio-fuel technology. They do not necessarily share the benefits, but they do share the renewable energy credits that flow from it.

An EU country may also enter into a joint project with a non-EU nation, and claim a portion of the credit, provided the project generates electricity and this physically flows into the union.

Statistical Transfers

A statistical transfer occurs when one member state has an abundance of renewable energy opportunities such that it can readily meet its targets, and has surplus credits it wishes to exchange for cash. It ?sells? these through the EU accounting system to a country willing to pay for the assistance.

This aspect of the cooperative mechanism provides an incentive for member states to exceed their targets. It also controls costs, because the receiver has the opportunity to avoid more expensive capital outlays.

Joint Support Schemes

In the case of joint support schemes, two or more member countries combine efforts to encourage renewable energy / heating / cooling systems in their respective territories. This concept is not yet fully explored. It might for example include common feed-in tariffs / premiums or common certificate trading and quota systems.

Conclusion

A common thread runs through these three cooperative mechanisms and there are close interlinks. The question in ecoVaro?s mind is the extent to which the system will evolve from statistical support systems, towards full open engagement.

2015 ESOS Guidelines Chapter 1 ? Who Qualifies

The base criteria are any UK undertaking that employs more than 250 people and/or has a turnover in excess of ?50 million and/or has a balance sheet total greater than ?43 million. There is little point in attempting to separate off high polluting areas. If one corporate group qualifies for ESOS, then all the others are obligated to take part too. The sterling equivalents of ?38,937,777 and ?33,486,489 were set on 31 December 2014 and apply to the first compliance period.

Representatives of Overseas Entities

UK registered branches of foreign entities are treated as if fully UK owned. They also have to sign up if any overseas corporate element meets the threshold no matter where in the world. The deciding factor is common ownership throughout the ESOS system. ecoVaro appreciates this. We have seen European companies dumping pollution in under-regulated countries for far too long.

Generic Undertakings that Could Comply

The common factor is energy consumption and the organisation’s type of work is irrelevant. The Environmental Agency has provided the following generic checklist of undertakings that could qualify:

Limited Companies Public Companies Trusts
Partnerships Private Equity Companies Limited Liability Partnerships
Unincorporated Associations Not-for-Profit Bodies Universities (Per Funding)

Organisations Close to Thresholds

Organisations that come close to, but do not quite meet the qualification threshold should cast their minds back to previous accounting periods, because ESOS considers current and previous years. The exact wording in the regulations states:

?Where, in any accounting period, an undertaking is a large undertaking (or a small or medium undertaking, as the case may be), it retains that status until it falls within the definition of a small or medium undertaking (or a large undertaking, as the case may be) for two consecutive accounting periods.?

Considering the ?50,000 penalty for not completing an assessment or making a false or misleading statement, it makes good sense for close misses to comply.

Joint Ventures and Participative Undertakings

If one element of a UK group qualifies for ESOS, then the others must follow suit with the highest one carrying responsibility. Franchisees are independent undertakings although they may collectively agree to participate. If trusts receive energy from a third party that must do an ESOS, then so must they. Private equity firms and private finance initiatives receive the same treatment as other enterprises. De-aggregations must be in writing following which separated ESOS accountability applies.

How Ventura Bus Lines cleaned up its Act

Melbourne?s Ventura Bus Lines grew from a single bus in 1924 to a mega 308-vehicle fleet by the start of 2014. The family-owned provider has always been community centric; when climate-change became an issue it took quick and urgent action. As a result it now stands head and shoulders above many others. Let’s take a closer look at some of its decisions that made the difference.

The Important Things to Focus On

Ethanol Buses ? Ventura is the only Australian company that uses ethanol power produced from sugar cane for experimental public transport. It compares emissions within its fleet, and knows that these produce significantly less CO2 while also creating jobs for locals.

Electric Buses ? The company has been operating electric buses since 2009. These carry 42 seated among a total 68 passengers. The ride is smooth thanks to twin battery banks kept charged by braking and forward momentum. When required, a two-litre VW engine kicks in automatically.

Ongoing Driver Training ? Ventura provides regular retraining sessions emphasising safe, environmentally-friending operations. Drivers are able to see their fuel consumption and carbon emissions online and experiment with ways to improve these.

Bus U-Turns ? The capacity to measure throughput convinced the company to abandon the principle that buses don’t do U-Turns for safety?s sake. Road re-engineering made this possible in a busy downtown street. This reduced emissions equivalent to 4,000 cars and reduced vehicle downtime for servicing.

Increased Business – These initiatives allowed Ventura Bus Lines to improve its service as customers experience it. This led to an uptake in patronage and a corresponding downturn in the number of passenger car hours. The pleasure of travelling green no doubt contributed to this.

How Measuring Made the Difference

Ventura Bus Lines is big business. Its 308 buses operate out of 5 depots, cover 31% of the metropole, and transport close to 70,000 passengers on average daily which is no minor task. The ability to track, measure and analyse carbon emissions throughout the area has earned it compliance with National Greenhouse Energy Reporting Threshold 1 legislation.

It also uses the data to re-engineer bus routes to further reduce fuel consumption, energy consumption and operating costs. It’s amazing how measuring is affecting its bottom line, and the health of the Melbourne community at large.
