Assessing policy and carbon price settings for incentivising reforestation activities in a carbon market: An Australian perspective

Policy makers often seek to incentivise reforestation to achieve either carbon abatement and/or the provision of other co-benefits such as landscape remediation, biodiversity, and social outcomes. But where incentives are for carbon abatement alone, uptake is often slower than expected, with previous estimates of economic viability for reforestation often overlooking some economic and technical barriers. Management of revegetation projects (e.g. species mix, configuration in belts or blocks and density of stocking) influences not only rates of sequestration of carbon (and therefore expected revenue from carbon markets), but also establishment and maintenance costs. These management factors were considered via a sensitivity analysis of a financial cash flow model of different scenarios of revegetation projects with respect to scale of operation of projects, quantification methodology applied, and type of payment contract.Results reinforced that policy makers seeking to incentivise revegetation for carbon abatement in addition to co-benefits such as landscape remediation may require additional crediting for these co-benefits as projects are often unviable with carbon payments alone. For example, simple linear tree plantings are likely to be most competitive in a market based solely on carbon abatement, while blocks of mixed-species biodiversity plantings would be uncompetitive given their relatively low rates of carbon sequestration and high establishment costs. Economic viability of revegetation projects may also be enhanced through: aggregation of projects to increase economies of scale; carbon markets allowing flexibility in approaches for quantification (e.g. application of calibrated models, or undertaking of direct field sampling), and; facilitating payment contracts that provide upfront capital through forward contracts.

Integrated planning for landscape diversity enhancement,fire hazard mitigation and forest production regulation: A case study in central Portugal

Forest fires and forest biodiversity are related issues of major concern in Mediterranean countries and require an integrated approach to landscape planning. The aim of this study was to develop a GIS approach for regulating forest production while promoting landscape diversity and mitigating fire hazard. A study area located in the centre of Portugal was chosen. The area was primarily occupied by maritime pine and had a high fire hazard, low tree species diversity and an extensive protection area. The classical area control method was used to assist in forest production regulation. Species suitability maps were produced for 21 recommended species for afforestation in the study area. Maritime pine management compartments were defined, and a 50-year harvesting plan was proposed. In each harvested compartment, protection areas were identified for species conversion (e.g., native oaks and/or broadleaves). Afforestation species were proposed according to the species suitability maps produced earlier. Low flammability species that produce high-quality wood, non-wood products and landscape enhancement were preferred. A comparison of the land cover in the study area in 2007 to that anticipated in 2064 via the proposed plan showed that a more fragmented landscape structure could be achieved by introducing 16 species of lower flammability than maritime pine into the study area. This study proved the usefulness of this methodological approach for guiding sustainable changes in homogeneous, unmanaged forest landscapes prone to fire. Further research is needed regarding integrated planning approaches that incorporate environmental, economic and social dimensions (e.g., human desertification of rural areas).

Reflexive loops on scaling issues in landscape quality assessment

Though most landscape ecologists have integrated scaling issues in their works, these issues are often disregarded in landscape perception and preference studies. Researchers base their studies on a predefined single scale to assess the landscape, and they pay little attention to the scale specificity of their analysis and recommendations. We reconsidered three landscape assessment studies from our research unit in light of scaling issues. In addition to the scale of the assessed landscape, researchers should address the scale of the landscape surrogate that is submitted for assessment, including the spatial references of the people surveyed and the target level of application of the results. Indeed, many of the landscape assessment methods mix different landscape notions and scales. Therefore, we recommend the cautious use of these assessments, the integration of qualitative insights in addition tithe scoring and paying attention to the perception scale, as defined by Fairclough (2006).
