Piggery: from environmental pollution to a climate change solution

Pig farms are a vital component of rural economies in Australia. However, disposal of effluent leads to many environmental problems. This case study of the Berrybank Farm piggery waste management system in Victoria estimates greenhouse gas (GHG) benefits from three different activities. Analysis reveals that the capturing and combusting of methane from piggery effluent could save between 4859 and 5840 tCO2e yr−1 ofGHGemissions. Similarly, using methane for replacing fuels for electricity generation could save another 800 tCO2e/yr of GHGs. Likewise, by utilizing the biogas wastes to replace inorganic fertilizers there could be a further saving of 1193 to 1375 tCO2e yr−1 of GHG, depending on the type of fertilizers the waste replaces. Therefore, a well-managed piggery farm with 15,000 pigs could save 6,852 to 8,015 tCO2e/yr, which equates to the carbon sequestrated from 6,800 to 8,000 spotted gum trees (age = 35 year) in their above plus below-ground biomass. Implementation of similar project in suitable areas in Australia could have significant environmental and financial benefits

Analysis of spacing for spotted gum plantations for maximising merchantable logs' volume in South East Queensland, Australia

Spotted gum (Corymbia citriodora subspecies Variegata) has the potential to be the major hardwood species for large-scale plantations in South East Queensland, Australia, but production research is limited due to the lack of age of research plots. Optimal spacing is a major subject of concern. Based on time series data from a spotted gum experiment site, growth performance is analysed for five spacing levels: ─11.3 m x 11.3 m (78 stems per hectare), 7.4 m x 7.4 m (182 sph), 5.4 m x 5.4 m (343 sph), 3.6 m x 3.6 m (771 sph) and 2.9 m x 2.9 m (1189 sph). The major objective was assumed to be to maximise total merchantable log volume. A growth model was produced, and the mean diameter at breast height (dbh) and total merchantable log volume for each spacing levels at a range of harvesting ages was estimated. From the analysis, the spacing level of 5.4 m x 5.4 m was found to be optimal for maximising merchantable log volume to 10 cm small-end diameter. Further analysis of mean dbh, height and volume of the largest 200 and 250 trees from this spacing level indicates that merchantable log volume could be maximised by retaining the 250 largest trees per hectare. The total financial revenue from the best spacing level in 25 and 30 years are predicted to be $13,637 and$17,779 per hectare, respectively. If full rotation data could be obtained, more reliable models could be produced, and a more accurate financial estimate could be made

Community based forest management systems in developing countries and eligibility for clean development mechanism

Concerns have been raised among the scientific communities about the increased atmospheric concentration of carbon dioxide (CO2). Carbon sequestration rates can be maintained or increased by afforestation, reforestation, avoided deforestation, forest preservation and particular tending and cultural operations on existing forests. Of these, afforestation and reforestation are the only eligible project activities under the Clean Development Mechanism (CDM). Of the three market-based mechanisms of the Kyoto Protocol (KP), CDM is the only one designed for developing countries where, coincidently, community based forest management systems (CBFMS) are becoming the main form of forest management. Under these systems, enhanced natural regeneration, forest preservation and wise utilization through different sets of cultural and tending operations are widely practiced in Africa, Asia and Latin America. These systems are often more compatible with the essence of the Convention on Biological Diversity (CBD) than are alternative management systems. Using Nepal as a case study, this paper highlights the importance of community forests in developing countries and then explains why many of them may not be eligible for CDM project activities. After that, some reasons why enhanced natural regeneration and forest preservation activities should be considered under the CDM project activities will be discussed. If community forests contribute to achieving the main objectives of CDM program as well as providing biodiversity benefits, and if they are the only socially acceptable and economically viable option, then they should be eligible under the CDM project activities. In particular, the CDM forest definition (>10% crown cover) should not be a barrier to their eligibility

Development of draft quality-of-governance standards for climate change mitigation and beyond: groundtruthing of developed verifiers in REDD+ pilot area, Nepal

Governance has been identified as central aspect of sustainable forest management. While all participants within the forest policy arena would agree with this observation, it has been less easy to determine how best to evaluate forest governance. Building on the work of the 1992 UN Statement of Forest Principles, and using a hierarchical framework of principles, criteria and indicators (PC&I), Dr Cadman has developed a consistent approach to evaluating forest governance at the global, regional, national and local levels. Tim and Tek applied their work to a range of global policy mechanisms, including REDD+, and has been used by the forest sector in developing countries (Nepal) to develop on-the-ground standards for evaluating REDD+ effectiveness and governance quality

Representing whose access and allocation interests? Stakeholder perceptions and interests representation in climate governance

This chapter presents a synthesis of findings from quantitative and qualitative investigations of the perspectives of participants involved in international climate governance, conducted over the period 2010-2015. In this study, an established framework of principles, criteria and indicators (PC&I) for institutional governance was applied to two mechanisms under the United Nations Framework Convention on Climate Change (UNFCCC): the initiative referred to as ‘Reducing emissions from deforestation and forest degradation and the role of conservation, sustainable management of forests, and enhancement of forest stocks in developing countries’ (REDD+); and the Clean Development Mechanism (CDM) of the Kyoto Protocol (KP). Assessment focuses on the governance value of interest representation in terms of inclusiveness (access) and resources (allocation). It begins by outlining the historical context of UNFCCC, as well as CDM and REDD+, and continues with a delineation of the methods adopted, and results to reveal a relatively consistent set of results across the elements investigated, with inclusiveness receiving the highest score of all the governance indicators, and resources the lowest. The CDM was the weakest performer

The role of fiscal instruments in encouraging the private sector and smallholders to reduce emissions from deforestation and forest degradation: Evidence from Indonesia

While developing countries around the world are preparing to implement REDD+, there is a debate on the possible role of fiscal instruments in encouraging the private sector and smallholder stakeholders in reducing emissions. Drawing on a case of Indonesia, an early leader on REDD+, this paper investigates the role of fiscal instruments in encouraging the private sector to reduce forest-based emissions and the implications for improving the forest sector governance. In particular the study highlights the perspectives of a range of forest sector stakeholders on the role of fiscal instruments that contribute either positively or negatively to reducing emissions from deforestation and forest degradation in Indonesia. The study comprised a review of the existing instruments in Indonesia, as well as surveys and interviews. An online survey and structured face-to-face interviews were conducted with a range of forest sector stakeholders, including government, civil society, academia, and palm oil concession holders. Findings indicate that there is a range of formal and informal fiscal instruments at the various jurisdictional levels, and a variety of incentives and disincentives. More emphasis on cross-sectoral co-ordination, alternatives to commodities such as palm oil, and continued land reform, is required

Scientific Forest Management Practice in Nepal: Critical Reflections from Stakeholders’ Perspectives

Design and application of context-specific forest management practices with the participation of key stakeholders plays a significant role in sustainable forest management outcomes. However, key forestry stakeholders often hold different, and sometimes conflicting, expectations in relation to forest management policies and management objectives. Applying the triple perspective typology of stakeholder theory, this paper assessed the evolution of 'Scientific Forest Management' (SciFM), a signature programme of the Nepalese Government, as well as its policy processes and explored compatibility, complexity, cost and relative advantages of the adoption of SciFM. The government believes that without this programme, Nepal is losing 91 Million US Dollar (USD) per year. This study revealed that participation of key stakeholders remained contested from the beginning of its implementation, primarily due to differences they held in understanding and interpretation of SciFM. Although stakeholders’ views converged on the potential role of SciFM to increase forest product supply and the domination of timber-centric management, their perspectives differed in nomenclature and implementation modality of SciFM. Primarily, the community forest users and their networks did not own the concept from the beginning, as they were suspicious of recentralization and bureaucratic dominance in forest governance through SciFM. Since historically ingrained skepticism in both government officials and community forest users’ networks towards each other has negatively influenced the trust building environment,the management of stakeholders’ relations through frequent and meaningful deliberations, and the simplification of bureaucratic procedures in implementation and capacity development of key actors could be instrumental in achieving SciFM objectives

An analysis of Australia's carbon pollution reduction scheme

The authors review the decision-making since the Labour Government came into office (November 2007). The Australian Government’s ‘Carbon Pollution Reduction Scheme’ White Paper (15 December 2008) proposes that an Australian Emissions Trading Scheme (AETS) be implemented in mid-2010. Acknowledging that the scheme is comprehensive, the paper finds that in many cases, Australia will take a softer approach to climate change through the AETS than the European Union ETS(EUETS). The paper assesses key issues in the White Paper such as emissions reduction targets, GHG coverage, sectoral coverage, inclusion of unlimited quantities of offsets from Kyoto international markets and exclusion of deforestation activities
