ABSTRACT

Implementation of forestry activities as a climate change mitigation option is likely to result in a range of outcomes in addition to carbon sequestration and these include changes with respect to environmental, social and economic aspects. These impacts to the extent when positive are deemed co-benefit and if adverse and uncertain, imply risk. It is important to recognize that implementation of forestry mitigation activities can have varied environmental, socio-economic co-benefits and/or risks. Further, there is no general agreement on attribution of co-benefits and risks to specific forestry mitigation activities. An overarching risk to mitigation potential that could be realised by implementation of forestry activities is climate change. But, overall, forestry mitigation activities also contribute to the sustainable development agenda. Maximizing co-benefits of forestry mitigation measures can increase efficiency in achieving the objectives of other international agreements.

1. Introduction

Mitigation, in the context of anthropogenic climate change, is a human intervention to reduce the sources or enhance the sinks of greenhouse gases (GHGs). Mitigation is intended to slow or halt climate change and is part of a broader policy framework that includes adaptation to climate impacts. Limiting the rate at which climate change is happening and keeping check on its magnitude is necessary to achieve sustainable development and equity, including poverty eradication. Mitigation, and adaptation to climate change contribute to the objective expressed in Article 2 of the UNFCCC to stabilize “greenhouse gas concentrations in the atmosphere at a level to prevent dangerous anthropogenic interference with the climate system ... within a time frame sufficient to allow ecosystems to adapt ... to ensure that food production is not threatened and to enable economic development to proceed in a sustainable manner”. Article 2 requires that “societies balance a variety of considerations some rooted in the impacts of climate change itself and others in the potential costs of mitigation and adaptation”. However, because mitigation and socio-economic developmental goals intersect, there could be tradeoffs [ 1 ].

Mitigation scenarios of IPCC [ 2 ] indicate a potentially vital role for land-related mitigation measures. Globally, the COP 21 agreement relies heavily on forests to achieve zero carbon emissions in the next half of this century which is a pre-requisite for limiting warming to a rise below 2˚C. Opportunities for mitigation in the AFOLU sector include supply- and demand-side mitigation options [ 2 ]. Supply-side measures involve reducing emissions arising from land use change, particularly reducing deforestation, land and livestock management, increasing carbon stocks by sequestration in soils and biomass, or the substitution of fossil fuels by biomass for energy production and biochar or wood products for energy intensive building materials. Demand-side measures include dietary change and waste reduction in the food supply chain and increasing forestry and agricultural production without a commensurate increase in emissions. IPCC [ 2 ] in its Fifth Assessment Report concluded that: “land-related mitigation, including bioenergy, is projected to contribute 20% to 60% of total cumulative abatement by 2030, and 15% to 40% by 2100”.

Climate mitigation actions on land may have benefits that go beyond global climate change mitigation and accrue at the local level [ 3 ]. These co-benefits tend to be local, rather than global. Identifying and accounting for them can reduce or partially compensate the costs of the mitigation measures. Forestry mitigation actions can have several environmental, social and economic effects [ 4 - 9 ]. The extent to which co-benefits and/or adverse side-effects or risks occur is dependent on local circumstances, implementation practices, as well as the scale and pace of the deployment of the different mitigation measures [ 10 - 16 ].

Many mitigation activities in the forestry sector affect land use or land cover and therefore, have socio-economic as well as ecological consequences. These include food security, livelihoods, ecosystem services or emissions [ 17 , 18 ]. These feedbacks make forestry mitigation challenging [ 19 - 23 ].

Thus, forestry mitigation activities are likely to result in a range of outcomes in addition to carbon sequestration and these include changes with respect to environmental, social and economic aspects. The extent to which co-benefits or trade-offs occur is dependent on local circumstances, implementation practices, as well as the scale and pace of deployment of the different mitigation measures. In this paper, the co-benefits and risks of implementing forestry mitigation activities are discussed.

2. Material and Methods

In literature, several methodological approaches have been identified to characterize and analyse the interactions between sustainable development and climate change responses. Several authors have suggested that sustainable development can be addressed as a framework for jointly assessing social, human, environmental and economic dimensions [ 24 ]. One way to address these dimensions is to use several economic, environmental, and social indicators to assess the impacts of policies on sustainable development, including both quantitative and qualitative measurement standards. However, the Fifth Assessment Report of the IPCC [ 2 ] concluded that emerging knowledge on the importance of ecosystems services as a means for addressing climate change mitigation and adaptation has brought attention to the role of ecosystem management for achieving several development goals, beyond climate change adaptation and mitigation. Different approaches are being adopted to valuate these services in some cases the individual components (both co-benefits and risks) are considered singly, while in other situations they are considered together [ 25 ].

2.1. The Co-Benefits Framework

Keeping the co-benefits and risks or adverse effects of the mitigation options being considered for the different land categories, a framework comprising of environmental, social and economic aspects has been developed for assessing the potential co-benefits and tradeoffs. This framework draws from the IPCC [ 2 ] framework proposed for co-benefits analysis. The gamut of environmental, social and economic sustainability issues is hard to identify. However, it is possible to develop a broad framework spanning thematic areas that could be used for screening the various mitigation options or strategies. The key thematic areas relevant to assessment of co-benefits of forestry mitigation activities are:

- Ecological:

• Biodiversity;

• Watershed protection;

• Soil protection.

- Social:

• Local community participation;

• Employment opportunity to local community;

• Gender representation;

• Competition for land for:

➢ Food production;

➢ Infrastructure and settlements.

- Economic:

• Increased employment;

• Increased income;

• Improved and increased flow of forest products: fuelwood, fodder, manure, Non-Timber Forest Products (NTFPs).

2.2. Forestry Mitigation Activities

In the context of global change and sustainable development, forest sector activities play a key role in mitigation of climate change. However, forests are also impacted by climate change and their contribution to mitigation may be influenced by stresses, possibly resulting from it. Socio-economically, forests are important because communities depend on the goods, services, and financial values provided by forests. Within this context, mitigation options must be formulated. It is important to note that carbon sequestration opportunities exist not only through afforestation and reforestation and forest conservation but also in agroforestry, farm forestry, homestead gardens and community fruit orchards, all of which qualify as forests under the UNFCCC. Potential mitigation activities and their co-benefits include:

- Afforestation on wastelands: Could potentially meet the fuelwood and industrial/structural wood requirements, generate non-timber forest products and reclaim land.

- Forest protection on moderately dense forests: Lead to conservation of the biomass of natural forest by halting deforestation and biodiversity conservation.

- Natural regeneration on open forests: Lead to regeneration and reclamation of degraded forest lands through protection and promotion of forest succession and biodiversity.

- Agroforestry on long fallow, marginal croplands and degraded pasture and grazing land: Produce timber species for economic returns and fruit yielding species for nutritional benefits and alternate and additional income. Afforestation on pasture lands provisions fodder species for livestock, reclamation of degraded land, watershed protection, etc.

The mitigation options identified in this assessment viz., forest protection, natural regeneration, agroforestry, and afforestation-short and long-rotation forestry are screened using the above co-benefits framework to assess for ecological, social and economic benefits and for synergies and tradeoffs with sustainable development goals. Further, the extent of impact of the mitigation options is assessed and categorised as high, medium and low.

3. Results and Discussion

Table 1 presents the co-benefits and risks of implementing forestry mitigation activities. It further

assesses the extent of these impacts and categorises them as high, medium and low. Below the co-benefits and risks classified broadly as environmental, social and economic co-benefits and risks are discussed.

3.1. Environmental Benefits and Risks

Benefits: Environmental co-benefits of implementation of forestry mitigation options-afforestation, natural regeneration, forest protection and agroforestry include 1) maintenance, conservation and promotion of biodiversity, 2) reclamation and restoration of degraded lands, 3) improvement in soil fertility, and iv) watershed services. Additionally, due to improvement in biodiversity, ecosystems are likely to become more resilient to changes in climate.

Risks: A potential negative impact of afforestation as a mitigation activity is promotion of monoculture plantations. However, this risk is mitigated as Forest Departments in India strictly promote multi-species plantations alone. Afforestation activities however may negatively impact water yield [ 26 ] and lead to negative consequences, particularly in drier areas, which is controversial and debatable.

3.2. Social Benefits and Risks

Benefits: Forestry mitigation activities promote livelihoods and provide sustained income to poor communities. They further result in provisioning of forest products such as fuelwood, fibre, food and construction materials after the initial establishment and growth period, particularly in case of long-rotation species such as teak or fruit orchards. Such provisioning of fruits and nuts is likely to lead to dietary changes because of availability of fruits for consumption to the poor communities. This would lead to overall improvement in the health of the communities.

Risks: Inequity in benefit-sharing may become a trade-off if a clear institutional framework for harvest and sharing of benefits is not formulated when forestry mitigation activities are implemented on public lands such as forestlands and wastelands. In cases, where agriculture land category is considered for forestry mitigation, food production may be impacted, causing food shortage and rise in price of food. However, in the case of Karnataka, it has been clearly demonstrated that such a negative impact is not likely to occur as agriculture production is unlikely to be affected given the past trends and the potential for producing more from existing area under agriculture.

3.3. Economic Benefits and Risks

Benefits: Forestry activities create employment opportunities. These include employment in nurseries where seedlings are to be raised, land preparation, planting of seedlings, thinning, maintenance and even harvest. Increased income from additional or new employment opportunities is yet another positive impact of forestry mitigation activities. Forestry mitigation activities to reduce forest loss and degradation are potential REDD+ activities that could draw financial incentives or attract financial mechanisms.

Risks: Potential negative impacts could be reduction in local income if communities are currently collecting timber and fuelwood and selling them in the market as a livelihood option. Communities would lose access to forest products, when forestry mitigation activities are implemented.

It is clear from this discussion and from Table 1 and discussions above that forestry mitigation options deliver multiple environmental, social and economic benefits. The extent of benefits, range from high to low across all categories as well as mitigation options, depending on the land categories on which these options are implemented-their degradation status and tenure. There are risks as well in implementing these options on different land categories, which will have to be avoided through planning and appropriate institutional and policy mechanisms.

3.4. Impact of Climate Change on Forestry Mitigation Potential

An overarching risk to forestry activities implemented for climate change mitigation is the impact of climate change on mitigation potential. Mitigation and adaptation in land-based ecosystems are closely interlinked. There is a web of feedback-synergistic or conflicting between mitigation and adaptation [ 27 - 29 ]. The mitigation options and potential themselves may be vulnerable to climatic change [ 30 ]. Reversals of mitigation benefits may be caused by natural events (such as forest fires and droughts) that affect growth. Such reversal effects may be temporary or short-term and will affect the annual increment of carbon, without probably resulting in a permanent decline in carbon stocks. But in case of a forest fire or incidence of insect or disease outbreaks, or drought, mitigation potential may decline significantly.

Climate change impact on carbon stocks in soils and forests including their adaptive capacity is important to actualize the mitigation potential [ 31 ]. Pervasive droughts and disturbances due to fire and insect outbreaks are likely to be exacerbated by climate extremes and long-term climate change [ 32 - 34 ] and these are a risk to the mitigation benefits of forests. Forest disturbances and climate extremes could impact the carbon balance and storage [ 35 - 39 ]. Thus, climate change could impact the potential and role land use sector can play in mitigating climate change.

3.5. Sustainable Development Goals

The Sustainable Development Goals (SDGs), officially known as Transforming Our World: The 2030 Agenda for Sustainable Development, are a set of seventeen aspirational “Global Goals”. Each goal has specific targets to be achieved over the next 15 years. As evident from the discussion in the previous section, forestry mitigation activities can potentially deliver multiple co-benefits. Maximizing co-benefits of forestry mitigation measures can increase efficiency in achieving the objectives of other international agreements. Forestry mitigation activities also have the potential to contribute to a broader global sustainability agenda [ 40 ]. Forestry mitigation activities clearly contribute to some of the SDGs of the United Nations.

The SDGs that the forestry mitigation activities directly contribute to include:

1) Goal 12.2: By 2030, achieve the sustainable management and efficient use of natural resources.

o Although the aim of forestry mitigation activities is carbon sink enhancement, the use of land categories such as wastelands and agriculture fallow lands that are under-utilized or unused promotes efficient use of land resource which is the goal of SDG 12.2. In case of the forestland category, forestry mitigation activities promote sustainable management of this land category as it is aimed at reducing forest loss and degradation, again a goal of SDG 12.2.

2) Goal 13: Take urgent action to combat climate change and its impacts.

o The forestry mitigation activities envisaged directly contribute to this SDG, by sequestering carbon as a mitigation action. Further forest conservation, leading to biodiversity conservation and linking forest corridors could reduce the impacts of climate change.

3) Goal 15: Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss.

o All the forestry mitigation activities are promoting sustainable use of terrestrial ecosystems as well as forests. Inclusion of wasteland category for forestry mitigation directly contributes towards the target of halting and reversing land degradation and inclusion of degrading moderately dense forests and open forests for forest conservation and regeneration will halt biodiversity loss.

It is evident from this analysis that there are significant opportunities for synergistically promoting mitigation and adaptation to climate change (Ravindranath, 2007), while enhancing conservation of biodiversity, and achieving other environmental as well as socio-economic benefits including meeting the sustainable development targets and goals.

4. Conclusions

Forestry mitigation thus offers a significant opportunity for combining carbon sink creation, local institutions, peoples’ participation, environmental improvement and livelihood issues. Barriers exist and have to be overcome through an integrated approach to realize the full potential. Forestry mitigation projects would play a multifunctional role that includes biodiversity conservation, improvement of ecosystem and yields of goods and services to the community generally, in addition to the overarching goal of climate change mitigation. Forestry mitigation activities deliver multiple environmental, social and economic benefits. In addition, some of the forestry mitigation activities such as agroforestry provide adaptation benefits as well, giving an opportunity for increasing ecological efficiency (Robledo et al., 2011). Among the four mitigation options, agroforestry scores high when it comes to delivery of environmental, social and economic benefits. Mitigation options for forestland-forest protection and natural regeneration score medium across all the co-benefit categories, while afforestation shows a mixed pattern. All these options have some risks associated with their implementation. Mitigation actions that promote sustainable development are likely to be viewed positively (Smith and Wollenberg, 2012). It is interesting to note that the forestry mitigation actions also contribute to achievement of Sustainable Development Goals and Targets of the United Nations. It is evident that forestry mitigation activities deliver multiple co-benefits including climate change adaptation. Many of these co-benefits are targets under the SDGs. Thus, forestry mitigation activities also contribute to the overall sustainable development agenda of a state and country.

“Maximizing co-benefits of forestry mitigation measures can increase efficiency in achieving the objectives of other international agreements”, including the Convention on Biological Diversity (CBD) and the United Nations Convention to Combat Desertification (UNCCD, 2011). These could also contribute to a broader global sustainability agenda (Gardner et al., 2012), whose implementation is sometimes limited by capital (Tubiello et al., 2009). Thus, mitigation is likely to provide a new source of finance.
