Reducing Emissions from Deforestation and Forest Degradation (REDD+) has been piloted in several developing countries. Limited funding available for REDD+ suggests that there is a need to adopt a targeted approach (i.e., targeting selected groups or regions) to make REDD+ projects more effective. However, there is no clear understanding of how targeting could be done based on households’ preferences for various design features of a REDD+ policy. Using choice experiment data obtained from two groups of households (project participants and outsiders) belonging to three types of forest management regimes (private, government and community) in Indonesia, this paper aims to identify classes of households that have similar preferences towards REDD+ design features. The scale adjusted latent class analysis indicates that there are four classes of households: (1) supporters emphasising household benefits, (2) supporters emphasising community projects, (3) indifferent but objecting restrictions, and (4) sceptics demanding monetary benefits. We also found that forest management regime is a key determinant of household classes. Our results suggest that REDD+ projects are likely to be more accepted by households in the community- and government-managed forest regimes. Such information will be useful to develop more targeted REDD+ projects.

减少毁林和森林退化造成的排放(REDD+)已经在几个发展中国家进行了试点。可用于REDD+的有限资金表明,有必要采用一种有针对性的方法(即,针对选定的群体或地区),以使REDD+项目更有效。然而,对于如何根据家庭对REDD+政策的各种设计特征的偏好来确定目标,目前还没有明确的认识。本文利用从印度尼西亚三种森林管理制度(私人、政府和社区)的两组家庭(项目参与者和局外人)中获得的选择实验数据,旨在确定对REDD+设计特征具有相似偏好的家庭类别。规模调整后的潜在阶级分析表明,有四类家庭:(1)强调家庭利益的支持者;(2)强调社区项目的支持者;(3)漠不关心但反对限制;(4)要求货币利益的怀疑论者。我们还发现,森林经营制度是家庭阶层的关键决定因素。我们的研究结果表明,在社区和政府管理的森林制度中,REDD+项目可能更容易被家庭所接受。这些信息将有助于制定更有针对性的REDD+项目。

In this paper, we explore the role of biofuel production on deforestation in low- and middle-income countries. Since the 2000s, biofuel production has been rapidly developing to address issues of economic development, energy poverty and reduction of greenhouse gas (GHG) emissions. However, the sustainability of biofuels is being challenged, particularly at the environmental level, due to their impact on deforestation and the GHG emissions they can generate as a result of land-use changes. In order to isolate the impact of bioethanol and biodiesel production among classic determinants of deforestation, we used a fixed effects panel model of 112 low- and middle-income countries between 2001 and 2012. Firstly, we found a positive relationship between bioethanol production and deforestation in these countries, among which we highlighted the specificity of Upper-Middle-Income Countries (UMICs). An acceleration of incentives for the production of biofuels from 2006 onwards enabled us to highlight higher marginal impacts for the production of bioethanol in the case of low- and middle-income countries and UMICs. Secondly, for low- and middle-income countries, these results are not significant before 2006. Thirdly, biodiesel production appears to have an impact on deforestation before 2006 on both subsamples. These last two results seem surprising and could be related to the role of biofuel production technologies and the crop yields used in their production.

在本文中,我们探讨了生物燃料生产对中低收入国家森林砍伐的作用。自2000年代以来,生物燃料生产迅速发展,以解决经济发展、能源贫困和减少温室气体(GHG)排放的问题。然而,生物燃料的可持续性正在受到挑战,特别是在环境层面,因为它们对森林砍伐的影响以及它们可能因土地利用变化而产生的温室气体排放。为了将生物乙醇和生物柴油生产的影响从森林砍伐的经典决定因素中分离出来,我们在2001年至2012年期间使用了112个低收入和中等收入国家的固定效应面板模型。首先,我们发现这些国家的生物乙醇生产与森林砍伐之间存在正相关关系,其中我们强调了中上收入国家(UMICs)的特殊性。从2006年起,对生物燃料生产的激励措施加速,使我们能够强调中低收入国家和中低收入国家对生物乙醇生产的更高边际影响。其次,对于低收入和中等收入国家,这些结果在2006年之前并不显著。第三,生物柴油的生产似乎对2006年之前的森林砍伐都有影响。最后两个结果似乎令人惊讶,可能与生物燃料生产技术的作用和生产中使用的作物产量有关。

Estimating annual investment returns from forestry and agriculture in New Zealand 估算新西兰林业和农业的年度投资回报

This paper describes a method of estimating annual investment returns from forest growing businesses in New Zealand, using financial statement data. The method is also applied to survey data (derived from farm financial statements) published by New Zealand pastoral farming sector organisations. After data are adjusted for inflation, the total investment return is calculated as the sum of the cash return on assets, and the percentage change in asset value. The paper demonstrates that the total investment return calculated in this way is equivalent to the internal rate of return (IRR), for a single period of one year. The direct equivalence between this measure and the single-period IRR (calculated using discounted cash-flow analysis) is demonstrated algebraically and by example.

Calculated values for forestry show a wide range of investment returns for different businesses in any one year, although there has been a general trend for total returns to increase for forestry businesses since about 2008. Investment returns for dairy and sheep and beef generally follow similar trends, with dairy providing a higher return on average than sheep and beef over the period studied. The data for forestry and agriculture are not directly comparable, since the forestry data are extracted directly from the financial statements of individual businesses and the farming data are derived through a process of averaging financial returns from a large number of farms, with the objective of providing typical returns for benchmarking. The scale of the operations are also significantly different, with the benchmark dairy farm being 148 ha, the sheep farm 764 ha and the forest businesses ranging from 21,000 ha to 150,000 ha (most recent year in all cases).

The measure of total return used in this paper is attractive because it means the same measure can be used for evaluating existing businesses as would have been used to justify the initial set up of the business, or any projects that contributed to the business along the way. This provides a measure for ex post evaluation of existing investments that is consistent with one of the ex-ante decision criteria used at the time investment decisions are made. The method also provides separate estimates of the income or productive return, and the (usually) unrealised change in asset value. The paper demonstrates that the method can be applied to either individual company or industry average financial data equally easily. This method provides a viable alternative to using survey data to estimate annual investment returns.

本文描述了一种估算新西兰森林种植企业年度投资回报的方法,使用财务报表数据。该方法也适用于调查数据(来自农场财务报表)由新西兰畜牧农业部门组织公布。根据通货膨胀调整数据后,总投资收益计算为资产的现金收益与资产价值变化百分比的总和。本文证明,以这种方法计算的总投资收益相当于一年期的内部收益率(IRR)。该指标与单期内部收益率(使用贴现现金流分析计算)之间的直接等价性通过代数和实例证明。林业的计算值显示,在任何一年中,不同业务的投资回报范围很大,尽管大约自2008年以来,林业业务的总回报有增加的总体趋势。乳制品、羊和牛肉的投资回报通常遵循类似的趋势,在研究期间,乳制品的平均回报高于羊和牛肉。林业和农业的数据不能直接进行比较,因为林业数据是直接从单个企业的财务报表中提取的,而农业数据是通过对大量农场的财务回报进行平均得出的,目的是为基准提供典型回报。经营规模也有很大不同,基准奶牛场为148 公顷,绵羊场为764 公顷,森林业务从21,000 公顷到150,000 公顷不等(所有情况都是最近一年)。本文中使用的总回报度量是有吸引力的,因为它意味着可以使用相同的度量来评估现有的业务,就像用来证明业务的初始设置一样,或者在此过程中对业务做出贡献的任何项目。这为现有投资的事后评价提供了一种方法,这种方法与作出投资决策时使用的事前决策标准之一是一致的。该方法还提供了收入或生产回报的单独估计,以及(通常)未实现的资产价值变化。本文表明,该方法既可以适用于单个公司财务数据,也可以适用于行业平均财务数据。这种方法为使用调查数据估计年度投资回报提供了一种可行的替代方法。

Forecasting the effect of carbon price and log price on the afforestation rate in New Zealand 预测碳价和原木价格对新西兰植树造林率的影响

The Emissions Trading Scheme (ETS) enacted in New Zealand in 2008 allows forest growers to claim units for carbon sequestered by new forests. As afforestation is an important contributor to New Zealand meeting net emission targets there is interest in forecasting the rate of afforestation, particularly how it will vary with the price of carbon in the ETS. Consequently a model is developed to estimate afforestation rate from the Land Expectation Value (LEV) of ‘traditional’ forestry (i.e., revenues only from log sales), the LEV from the carbon trading opportunity that the ETS creates, and land value.

Initially the relationship between afforestation rate and A grade log price during the period 1988 and 2008 is considered. Then the relationship between afforestation rate and LEV is evaluated. Initially the period up to 2008 is considered to evaluate the impact of ‘traditional’ forest profitability on the afforestation rate. Then the period from 2009 to 2015 is included and the impact of carbon is introduced. Finally the cost of land is introduced into the model.

The land affordability model developed allows the future afforestation rate to be forecast from carbon price, log price and land value.

2008年在新西兰颁布的碳排放交易计划(ETS)允许森林种植者申请新森林所吸收的碳的单位。由于植树造林是新西兰实现净排放目标的重要因素,人们对预测植树造林率很感兴趣,特别是它将如何随排放交易体系中的碳价格而变化。因此,开发了一个模型,根据“传统”林业的土地期望值(即仅来自原木销售的收入)、ETS创造的碳交易机会的LEV和土地价值来估计植树造林率。首先考虑了1988年和2008年A级原木价格与造林率的关系。在此基础上,评价了植树造林率与LEV之间的关系。最初,到2008年的这段时间被认为是评估“传统”森林盈利能力对植树造林率的影响。然后纳入2009年至2015年期间,并介绍了碳的影响。最后,将土地成本引入模型。建立的土地可负担性模型可以通过碳价、原木价和土地价值来预测未来的植树造林率。

The expansion of nature-based tourism on private land requires new mechanisms to coordinate tourism industry and commercial forestry interests. This attribute-based contingent valuation study elaborated the supply side of potential payments for ecosystem services (PES) mechanism named Landscape and Recreational Values Trading (LRVT), proposed to enhance the provision of amenity values in privately owned forests located in tourism and recreation areas. Using a mail survey data set, we analyzed forest owners’ willingness to participate in LRVT and the related compensation claims in the Ruka-Kuusamo area, Finland. We found that more restrictive rules regarding forest management practices decrease the probability of participating and increase forest owners’ compensation claims in LRVT. Furthermore, forest owners seem to claim more compensation if, instead of private negotiations, competitive tendering is used to make contracts. Moreover, besides the protection of landscape values, biodiversity protection may be a motive for participation. This indicates that, in addition to improved landscape quality, respondents gain personal benefits from enhanced biodiversity in their own forests. The results can help in designing and implementing a future payment mechanism for the provision of forest landscape and recreational values in terms of how to proceed and whom marketing and recruiting efforts should target.

在私人土地上扩大自然旅游需要新的机制来协调旅游业和商业林业利益。这项基于属性的条件价值评估研究阐述了生态系统服务潜在支付(PES)的供给侧机制,即景观和休闲价值交易(LRVT),提出了在旅游和休闲区内的私人拥有森林中提供舒适价值的建议。利用邮件调查数据集,分析了芬兰Ruka-Kuusamo地区森林所有者参与LRVT的意愿和相关的赔偿要求。研究发现,森林管理实践的限制性规则越严格,森林所有者参与的可能性越低,森林所有者的赔偿要求也越高。此外,如果用竞争性招标代替私人谈判订立合同,森林所有者似乎要求得到更多的补偿。此外,除了保护景观价值外,保护生物多样性可能是参与的动机。这表明,除了改善景观质量外,受访者还从自己森林的生物多样性增强中获得了个人利益。研究结果可以帮助设计和执行未来的支付机制,以提供森林景观和娱乐价值,包括如何进行以及销售和征聘工作应以谁为目标。

Establishing conservation areas to protect biodiversity often results in economic trade-offs from reduced market opportunities for natural resource extraction. The purpose of this study was to quantify the economic impacts of two proposed conservation area scenarios in the Lower Peace Region of Alberta to determine the potential magnitude of the economic trade-offs. The first scenario, known as the Lower Athabasca Regional Plan (LARP), was proposed by the Government of Alberta under the Alberta Land-use Framework. The second scenario, referred to as the alternative scenario, was developed by the authors using a spatial land-use rationalization process. Economic impacts of each conservation area scenario were estimated using a dynamic, computable general equilibrium model for the province of Alberta. Results indicated that the two scenarios will have very similar impacts and may reduce the present value of GDP by as much as $4.44 billion in Alberta from 2011–2056. These findings highlight the importance of considering the economic impacts of conservation area strategies in order to minimize the trade-offs associated with achieving conservation goals.

建立保护区以保护生物多样性往往会导致经济上的权衡,减少自然资源开采的市场机会。本研究的目的是量化阿尔伯塔省下和平地区两种拟议保护区方案的经济影响,以确定经济权衡的潜在幅度。第一种方案被称为下阿萨巴斯卡区域计划(LARP),由艾伯塔省政府根据艾伯塔省土地使用框架提出。第二种情景,称为备选情景,是作者利用空间土地利用合理化进程拟订的。利用艾伯塔省的动态、可计算的一般平衡模型估计了每个保护区情景的经济影响。结果表明,这两种情况将产生非常相似的影响,并可能从2011-2056年减少阿尔伯塔省GDP的现值高达44.4亿美元。这些发现强调了考虑保护区战略的经济影响的重要性,以便最大限度地减少与实现保护目标相关的权衡。

Continuous-cover forestry is a management alternative that seeks to provide more diverse forests for continual multi-purpose benefits. Whether there is an economically-optimal equilibrium of uneven-aged forest can be tested deterministically by varying interest rate i. To answer this question, optimisation focused on maximising the net present value for the long-term period was performed using the Subplex algorithm integrated within a density-dependent stand-level matrix transition model. A regular-grid inventory of mixed uneven-aged forests in the West Carpathians, Central Slovakia, was used to parameterise the model. The results showed that a steady state can be reached that is characterised either by a near equilibrium at an i of 1% and higher, or by a continuous fluctuation at an i of 0% and 0.5%. When starting optimisation with a real stand situation with i of 2% and higher, deviations from an equilibrium state appeared both at the beginning and end of the optimisation run. The conclusion is therefore to only interpret the middle-stabilised sequence from the long-term optimisation results as a real equilibrium. Considering the individual target diameter specific for crown size and stem quality of trees within the extended matrix model improved the financial results by 7%. Crown size, representing tree vigour and growth potential, was more important for the improvement of financial results compared to stem quality related to timber price.

连续覆盖森林是一种管理选择,旨在提供更多样化的森林,以获得持续的多用途效益。是否存在不均匀年龄森林的经济最优均衡,可以通过改变利率来确定地检验。为了回答这个问题,我们使用与密度相关的林分水平矩阵转换模型相结合的Subplex算法,对长期净现值最大化进行了优化。在斯洛伐克中部的西喀尔巴阡山脉的混合不均匀年龄森林的规则网格库存被用于参数化模型。结果表明,可以达到稳定状态,其特征是在i为1%或更高时接近平衡,或在i为0%和0.5%时连续波动。当在i为2%或更高的实际情况下开始优化时,在优化运行的开始和结束时都会出现与平衡状态的偏差。因此,结论是只能将长期优化结果中的中间稳定序列解释为真正的平衡。在扩展矩阵模型中考虑树冠大小和树干质量的个别目标直径,使财务结果提高了7%。与与木材价格有关的茎质量相比,代表树木活力和生长潜力的树冠大小对改善财务结果更为重要。

In September 2010, the Fourmile-Lefthand Canyon forest fire burned 6181 acres, destroyed 169 homes, and caused $217 million in property damages making it by far the most expensive fire in Colorado history at the time. This paper examines how the fire affected housing prices in vulnerable neighboring areas that were not directly impacted by the fire, controlling for the property’s level of risk. This damaging fire may have increased home owners’ perceptions about the risk of living in forested areas subject to wildfires to a significant degree adding to the total direct economic losses from the fire. Utilizing a unique fire risk data set and a difference-in-difference approach, we test whether buyers of houses in areas with different risk levels prior to the fire adjust expectations differently. We find buyers in the highest risk area are most likely to change their perceptions in response to a fire with houses in these areas experiencing a statistically significant 21.7% decline in sale price compared to houses in non-risky areas.

2010年9月,左手四英里峡谷森林大火烧毁了6181英亩土地,摧毁了169所房屋,造成了2.17亿美元的财产损失,成为当时科罗拉多州历史上最昂贵的火灾。本文考察了火灾对未受火灾直接影响的脆弱邻近地区的房价的影响,控制了财产的风险水平。这场破坏性的火灾可能增加了房主对生活在森林地区的风险的认识,这在很大程度上增加了火灾造成的直接经济损失。利用独特的火灾风险数据集和差异中的差异方法,我们测试了火灾前不同风险水平地区的房屋购买者是否调整了不同的预期。我们发现,风险最高地区的买家最有可能改变他们对火灾的看法,与非风险地区的房屋相比,这些地区的房屋销售价格在统计上显著下降了21.7%。

What ethanol prices would induce growers to switch from agriculture to poplar in Alberta? A multiple options approach 在阿尔伯塔省,什么样的乙醇价格会促使种植者从农业转向杨树?多种选择方法

The emergence of second generation biofuel industries will be heavily dependent on future prices of ethanol, which could incent landowners to switch land uses from agriculture to growing biofuel feedstocks. In this study, we investigate price levels of ethanol that will be necessary for landowners to grow hybrid poplar. In such an emerging industry, landowners will face a great deal of uncertainty and will consider options to change their production decisions over time. To address this uncertainty, we construct a real options model that considers the dynamic option for Canadian landowners to switch from agriculture to poplar plantations, and also the option to sell poplar plantations for ethanol or pulpwood. The uncertainty in prices for poplar is characterized by time series models of prices for ethanol and pulpwood that characterize price variability as a GARCH process, and reversion to the long term mean average prices. Uncertainty for the value of land allocated to agriculture is characterised by a geometric random walk. Given these price processes, the real options models suggest that current average price levels would have to increase by approximately 35% (i.e. by 0.21 $/L) if only ethanol is considered as an end product, but this increase may be reduced to 32% (i.e., to 0.19 $/L) if the landowner has options to sell the poplar to either ethanol or pulpwood producers. On low value agriculture lands, estimates suggest that an 18% increase relative to current ethanol prices (i.e., of 0.11 $/L) would be needed, which is approximately equal to the current second generation subsidies in Alberta.

第二代生物燃料产业的出现将严重依赖于乙醇的未来价格,这可能会激励土地所有者将土地用途从农业转向种植生物燃料原料。在这项研究中,我们调查了乙醇的价格水平,这将是土地所有者种植杂交杨树所必需的。在这样一个新兴产业中,土地所有者将面临很大的不确定性,并将考虑随着时间的推移改变其生产决策。为了解决这种不确定性,我们构建了一个真实期权模型,该模型考虑了加拿大土地所有者从农业转向杨树种植园的动态期权,以及出售杨树种植园以获取乙醇或纸浆木的期权。杨树价格的不确定性通过乙醇和纸浆木价格的时间序列模型来表征,该模型将价格变化表征为GARCH过程,并回归到长期平均价格。分配给农业的土地价值的不确定性表现为几何随机游走。考虑到这些价格过程,实物期权模型表明,如果只将乙醇视为最终产品,目前的平均价格水平将不得不增加约35%(即0.21美元/升),但如果土地所有者有权将杨树出售给乙醇或纸浆生产商,这一涨幅可能会减少到32%(即0.19美元/升)。据估计,在低价值农业用地上,相对于目前的乙醇价格,将需要增加18%(即每升0.11美元),这大约相当于阿尔伯塔省目前的第二代补贴。

Global aspirations, regional variation? Explaining the global uptake and growth of forestry certification 全球抱负,地区差异?解释全球对林业认证的吸收和增长

Private governance, in the form of certification schemes, has grown remarkably in the past decades as a response to some of the most pressing environmental and social challenges. Certification schemes denote steering mechanisms that allow enterprises to voluntarily adhere to a set of verifiable principles. While certification has global aspirations, its uptake and growth are heterogeneous across different countries. Yet, few studies empirically analyze such variation. We address this gap by focusing on the Forest Stewardship Council, a major sustainable forestry management certification program. We empirically evaluate uptake and growth across 151 countries and hypothesize that market and socio-political characteristics explain variation in uptake and growth. We find that a value-added wood industry, state-control of the forestry industry and competing certification programs, contrary to the literature, are key drivers.

作为对一些最紧迫的环境和社会挑战的回应,以认证计划形式出现的私人治理在过去几十年中得到了显著发展。认证方案是一种指导机制,允许企业自愿遵守一套可验证的原则。虽然认证具有全球性的抱负,但不同国家对它的吸收和增长却不尽相同。然而,很少有研究对这种差异进行实证分析。我们通过关注森林管理委员会(一个主要的可持续森林管理认证项目)来解决这一差距。我们对151个国家的吸收和增长进行了实证评估,并假设市场和社会政治特征解释了吸收和增长的差异。我们发现,与文献相反,增值木材产业、国家对林业产业的控制和竞争性认证计划是关键驱动因素。
