Strong links to land deliver better health outcomes


Around the time the Prime Minister’s ‘Closing the Gap’ report was released in February, the Desert Knowledge Cooperative Research Centre (CRC) published a comprehensive report outlining four principles for Aboriginal land management. Researchers say these principles will help improve health and well-being for indigenous communities.

The ‘Closing the Gap’ report raised particular concerns about achieving one of the six key targets – closing the life expectancy gap between Aboriginal and non-Aboriginal Australians – which is currently 11.5 years for men and 9.7 years for women. The report noted that while the life expectancy of indigenous people increased over 1991–2008, the ‘gap’ may not close for some years, because the life expectancy of non-indigenous people has been rising at a faster rate.1

For Aboriginal communities in inland Australia at least, connections with land can help them achieve a better state of health, says Dr Jocelyn Davies of CSIRO Ecosystem Sciences – lead author of the Desert Knowledge CRC report.2 Dr Davies and her colleagues formulated four ‘Livelihoods inLand™’ principles after analysing a large body of published scientific work.3

‘Aboriginal people commonly say that their health and well-being are positively impacted by a strong relationship with their traditional lands and culture, and there is increasing scientific evidence that this is the case,’ says Dr Davies.

‘People’s sense of control or capacity to cope, and the serious health impacts of sustained stress, are powerful factors explaining this relationship. The stress load on Aboriginal people is reduced when they are empowered through caring for their own lands.’

A team headed by Mr David Campbell, senior economist at the Centre for Remote Health, has identified potential positive health impacts of Aboriginal involvement in land management. Mr Campbell’s team estimated that a health centre in a northern Australian community of 1200 people saves about $270 000 annually (or a net present value of $4 million) in primary treatment costs for hypertension, renal disease and diabetes.4

Aboriginal land management can involve cultural or customary activities, natural resource management, conservation work that supports environmental health in the local settlement, and land-based enterprises such as bush foods and tourism.

‘All these activities help to improve physical fitness and create a healthier lifestyle, and they can also endow people with a greater sense of control, which is a powerful way to reduce and manage stress and its health impacts,’ notes Dr Davies.

The four principles proposed by the researchers are:

  1. Aboriginal land management governance recognises and respects Aboriginal custom and tradition, and is adaptive

  2. learning is embraced as a lifelong process

  3. relationships are recognised as very important

  4. partnerships give priority to doing things that all parties agree are important.

‘These principles need to be considered together with other things that are important for anyone’s health, like good food, exercise, not smoking or drinking heavily, and good parental care, in the case of children,’ says Dr Davies.

‘The principles are equally important for understanding and promoting resilience, adaptive capacity and healthy transformations in the social-ecological systems of desert Australia.’

Dr Davies adds that being responsible for land allows traditional Aboriginal communities to hand down ecological knowledge to future generations, and also provides pathways for acquiring scientific knowledge.

The four principles also support Aboriginal landowners and organisations interested in being involved with developing environmental certification of goods and services. Dr Davies says this is important for generating new investment to support employment in Aboriginal land management.

‘Internationally there is a growing trend for certification of goods and services that contribute to tackling global warming and that also benefit local communities,’ she says.

Dr Davies adds that the Livelihood inLand™ research principles provide a foundation for new research at the CRC for Remote Economic Participation, which is aimed at understanding how culture and connection to land, education and employment interact to deliver better standards of health and well-being.

Zero Carbon Australia plan, revisited

Matthew Wright and Patrick Hearps

In 2010 the Beyond Zero Emissions group released a report with the University of Melbourne’s Energy Research Institute claiming that Australia could be powered by renewable energy sources by 2020. Here its lead authors reply to some of the points raised by Dr Mark Diesendorf’s review of the report in ECOS 157.

The Zero Carbon Australia (ZCA) Stationary Energy Plan sets out strategies for powering Australia with 100 per cent renewable energy by 2020. While the plan stands alone as the only technical blueprint for completely decarbonising the domestic energy sector, it is a work in progress. There are areas to improve and some clarifications we would like to make about some of the recommendations.

Our research was undertaken with two explicit parameters: energy technologies selected had to be both commercially available and from carbon-free renewable energy sources. This explains why the ZCA Plan identifies a 60/40 mix of concentrated solar thermal (CST) power and large-scale wind developments as the backbone of a decarbonised energy system. Together with existing hydropower, investment in CST with molten salt storage, backup from a small percentage of biomass power, an upgraded electricity grid, and comprehensive energy efficiency measures, Australia can reliably meet its energy needs from renewable electricity generation. The technologies selected were not preordained; rather they were chosen on the basis that they worked within ZCA’s parameters.

The ZCA scenario also includes natural gas. Under the plan, Australia would use existing gas infrastructure in a staged scale-back, until the last gas power plants are mothballed in 2020. The most carbon-intensive coal power plants must be first to be decommissioned as large-scale renewables come online, made possible by the deployment of CST power towers with molten salt storage for 24-h operation.

CST is a nascent, commercially available energy technology. At November 2010, there were 632.4 electrical megawatts (MWe) of CST operating in Spain, including 250 MWe with storage, and a further 422 MWe in the US. Another 2000 MWe are in advanced stages of construction and development in Spain. This project pipeline amounts to over a US$20 billion investment. Meanwhile, in the US, federal loan guarantees and cash grants have fostered the approval of over 4 000 MW of CST, many of which have begun construction.

The CST plants in the ZCA Plan are modelled on the Spanish Gemasolar plant, which is now dispatching electricity to the Spanish grid. Our cost projections are based on those from existing projects in the US and Spain, with provisions for significant cost reductions following the first 1000 MWe installed.

The infrastructure rollout proposed under the ZCA plan, including these CST plants, is well within Australia’s industrial capability. Dr Diesendorf presents a global shortage of electrical engineers as a constraining factor. However, CST plants constructed under the ZCA plan would be replicated with a standardised series of plants, reducing the need for electrical engineers who are mostly required during the design phase.

As to the value of an east–west transmission link, more detailed modelling will be conducted for version 2.0 of the ZCA plan. Even without this data, it is premature to rule out the cost effectiveness of a transcontinental grid. Siemens proposes an east–west link in its 2010 report Picture the Future: Australia – Energy and Water. High-voltage direct current (HDVC) infrastructure is already in widespread use in the US, Canada, Europe and South America, and China has now commissioned the 2071 km Xiangjiaba-Shanghai 800 kV Ultra HVDC link.

The ZCA plan puts forward a single scenario largely in order to identify the specific challenges around implementation. We do not claim that the current iteration of the ZCA plan is the optimal solution. We would like to invite engineers and scientists from around Australia to provide their services as pro bono researchers with the Zero Carbon Australia project and make version 2.0 an even stronger document than the first.

We don’t think the Zero Carbon Australia initiative is brave. We think it’s necessary.
