Using measures of wellbeing for impact evaluation: proof of concept developed with an Indigenous community undertaking land management programs in northern Australia

Abstract Combining insights from literature on the Theory of Change, Impact Evaluation, and Wellbeing, we develop a novel approach to assessing impacts. Intended beneficiaries identify and rate factors that are important to their wellbeing, their satisfaction with those factors now, and before an intervention. Qualitative responses to questions about perceived changes and causes of change are linked to quantitative data to draw inferences about the existence and/or importance of impact(s). We use data from 67 Ewamian people, in a case study relating to Indigenous land management, to provide proof of concept. ‘Knowing that country is being looked after’ and ‘Having legal right/access to the country’ were identified as important to wellbeing, with perceptions that Native Title determination, declared Indigenous Protected Area and associated land management programs have had a significant and positive impact on them. Further method testing might determine the utility of this approach in a wide range of settings.

Using insights about key factors impacting ‘quality of life’ to inform effective on-farm conservation programs: a case study in Northern Australia

ABSTRACT Conservation of biodiversity is an ongoing challenge. Governments face many constraints when pursuing conservation, one of the most pervasive being limited budgets for buying land for conservation. To achieve conservation goals, an alternative to acquisition is on-farm conservation. Research suggests that the success of on-farm conservation programs depends primarily on land managers’ behaviour. In the past, one of the tools used for on-farm conservation has been financial incentives but these may be ineffective if they do not align with the intrinsic motivations of land managers. Our paper seeks to learn more about the intrinsic motivations of land managers by learning more about what contributes to their overall quality of life (life satisfaction). We hypothesize that by understanding the drivers of land manager’s subjective assessments of their own life satisfaction we will be able to shed light on the types of incentives that could help promote on-farm conservation. Our analysis highlights that good relationships are the most important contributor to land managers’ life satisfaction. We conclude that programs which help maintain good social networks whilst encouraging on-farm conservation are likely to align with intrinsic motivations of land managers and might therefore be more successful in making genuine additional contributions to biodiversity than programs providing only financial incentives.

Are Indigenous land and sea management programs a pathway to Indigenous economic independence

This paper focuses on Indigenous business development, an under-researched co-benefit associated with investment in Indigenous land and sea management programs (ILSMPs) in northern Australia. More than 65% of ILSMPs undertake commercial activities that generate revenue and create jobs. In addition to generating environmental benefits, ILSMPs thus also generate economic benefits (co-benefits) that support Indigenous aspirations and help to deliver multiple government objectives. We outline key features of northern Australian economies, identifying factors that differentiate them from Western urbanised economies. We discuss literature highlighting that, if the aim is to stimulate (short-term) economic development in northern Indigenous economies, then the requirement is to stimulate demand for goods and services that are produced by Aboriginal and Torres Strait Islander people (herein referred to as Indigenous people), and which generate benefits that align with the goals and aspirations of Indigenous people. We also discuss literature demonstrating the importance of promoting a socio-cultural environment that stimulates creativity, which is a core driver of innovation, business development and long-term development. ILSMPs have characteristics suggestive of an ability to kick-start self-sustaining growth cycles, but previous research has not investigated this. Using 8 years of data relating to Indigenous businesses that are registered with the Office of the Registrar of Indigenous Corporations (a subset of all Indigenous businesses), we use statistical tests (Granger causality tests) to check whether ILSMP expenditure in the first year has a positive impact on Indigenous business activity in subsequent years. This analysis (of admittedly imperfect data) produces evidence to support the proposition that expenditure on ILSMPs generates positive spillovers for Indigenous businesses (even those not engaged in land management), albeit with a 3-year lag. ILSMPs have been shown to be an appropriate mechanism for achieving a wide range of short-term benefits; our research suggests they may also work as catalysts for Indigenous business development, fostering sustainable economic independence.

If climate change means more intense and more frequent drought, what will that mean for agricultural production? A case study in Northern Australia

ABSTRACT We examine the influence of drought and a variety of factors on agriculture in Northern Australia. Assuming constant prices, and using data collected from northern land managers, we estimate a Cobb–Douglas production function and use coefficients from the model to estimate the financial losses associated with drought. We find that drought-affected properties earn about half as much as other ‘similar’ properties. We then ask: How much does that ‘cost’ the industry, on average, and how would those costs change if droughts were to become more, or less widespread under climate change? Our estimates indicate that under the current climatic regime, the Northern Australian agricultural industry loses, on average, about 19% of output to drought each year: this could fall to 10% or rise to 40% under current climate projections. Although focused on Northern Australia, the findings have wider implications for management and adaption, given the magnitude of impacts and their likelihood to extend beyond the ‘official’ end of drought. Investments in climate-proof crops, on-farm management techniques and financial arrangements to help producers deal with a range of climatic risks, for example, should thus be priorities.

Assessing the impact of price changes and extreme climatic events on sediment loads in a large river catchment near the Great Barrier Reef

Ocean turbidity (associated with sediment from rivers) can significantly impact reef health. In Australia, there are many plans to reduce sediment loads by encouraging best management practices; there is also interest in the use of market-based instruments. But it is exceedingly difficult to assess the potential efficacy of market policies, since that requires one to determine how changes in the socio-economic system (e.g. price changes) impact the biophysical (e.g. sediment loads). We use historical data (from 1938 to 2011) in a vector autoregression model to simultaneously model interactions between the economic and biophysical systems in the Burdekin River catchment adjacent to the Great Barrier Reef (GBR) lagoon. This allows us to statistically test for the impact of changes in prices on sediment load, while controlling for biophysical influences. We find that extreme events have the most impact on sediment loads, but that prices also impact sediment loads. Evidently market-based policies may have the potential to reduce sediment loads. Our empirical results provide useful information for those interested in the Burdekin River catchment and the GBR; the modelling approach may have wide applicability in a variety of contexts.
