Introduction
Over the past 10 years the international community has sought to make the protection of forests a key element of plans for addressing climate change. The idea is to reduce emissions from deforestation and forest degradation (REDD+) and to enhance the role of conservation and sustainable management of forests in developing countries. REDD+ developed from the initial idea of avoided deforestation (Humphreys, Reference Humphreys2008): the idea that because forests can sequester significant amounts of carbon, and because carbon emissions are linked to climate change, protecting forests is a vital way of protecting the world from climate change. The idea is to compensate developing countries that reduce carbon emissions from forests (Santilli et al., Reference Santilli, Moutinho, Schwartzman, Nepstad, Curran and Nobre2005). Following years of conversations in the international community, REDD was agreed by the Parties to the United Nations Framework Convention on Climate Change during COP-13 (the 13th Conference of the Parties) in Bali, Indonesia, in 2007. In 2008, barely 1 year after REDD was formally accepted (in principle), its scope was broadened to include other possibilities, on the grounds that ‘climate benefits can arise not only from avoiding negative changes (deforestation, degradation), but also from enhancing positive changes, in the form of forest conservation and restoration’ (Wertz-Kanounnikoff & Kongphan-apirak, Reference Wertz-Kanounnikoff and Kongphan-apirak2009). Thus, at COP-14 in Poznań, Poland, in 2008, REDD became REDD+ in recognition of these other possibilities. Some scholars and agroforestry researchers (e.g. Sayer et al., Reference Sayer, Sunderland, Ghazoul, Pfund, Sheil and Meijaard2013; Naughton-Treves & Wendland, Reference Naughton-Treves and Wendland2014; Minang et al., Reference Minang, Van Noordwijk, Freeman, Mbow, De Leeuw and Catacutan2015; Turnhout et al., Reference Turnhout, Gupta, Weatherley-Singh, Vijge, De Koning and Visseren-Hamakers2016) have advocated for a broader scope for REDD+, calling for an approach that encompasses all land-use activities, arguing that such an approach would significantly reduce terrestrial emissions (Herold, Reference Herold2013). This holistic approach has been deemed the landscape governance approach; that is, a comprehensive and integrative multi-functional use of land to foster interaction between sectors such as forests, agriculture, biodiversity, natural resource conservation, and their actors and institutional systems, to achieve social, economic and environmental objectives (Minang et al., Reference Minang, Van Noordwijk, Freeman, Mbow, De Leeuw and Catacutan2015).
Even though climate treaty negotiations (in Doha 2012, Warsaw 2013, Lima 2014, Paris 2015, and Marrakesh 2016) have endorsed a landscape governance approach, and such an approach is largely promoted by the Global Landscapes Forum (GLF, 2013), it presents new challenges, as well as some opportunities for enhanced conservation. Therefore, the implications of a landscape governance approach to REDD+ for conservation and tropical forest governance should be a priority for researchers and policy makers. As the international community debates the possibility of accepting a landscape governance approach, it is vital to examine the potential challenges and opportunities the approach may present to conservation and forest governance beyond forests. Here I examine two probable features of the landscape governance approach: carbon-farming in grasslands and in plantations.
Although a number of carbon-farming initiatives are currently being undertaken (e.g. revegetation of agricultural land using woody tree species, and soil carbon enhancement techniques such as no-till farming), I focus here on grasslands because under the landscape approach grasslands “may contribute more to the ‘missing sink’ than was previously appreciated” (Scurlock & Hall, Reference Scurlock and Hall1998), and on plantations because under the landscape approach an across-the-board definition of ‘forests’ that includes plantations may be adopted, thus increasing forest carbon sequestration offsets.
Methods
To evaluate challenges and opportunities associated with adopting a landscape governance approach I reviewed the literature and conducted a focus group at the Association of American Geographers Annual Meeting in San Francisco, USA, on 30 March 2016. Thirty-five members of conservation groups, REDD+ scholars, and members of the REDD+ agroforestry research community participated in the focus group discussion. Participants were recruited from the Association's list of specialty group sessions by identifying potential participants and inviting them to join the focus group. I randomly divided participants into seven groups of five people, aiming for homogeneity (to take advantage of participants’ shared experiences) and diversity (to capitalize on different perspectives) within the groups. I presented a documented history of the landscape approach to participants, asked them open-ended questions in relation to the REDD+ programme adopting the approach, and encouraged them to report their own experiences. The discussion groups met 2–3 times. Here I analyse the transcripts of these discussions, describe the areas of agreement and disagreement, and offer some recommendations to facilitate conservation while minimizing any potential damage from the landscape governance approach.
Results
I found three encompassing themes permeating the seven focus groups.
Theme 1: Risks of carbon-based conservation
In many of the focus groups members expressed concerns about dangers of carbon-based conservation. Participants discussed management interventions aimed at increasing carbon stock that are deleterious to biodiversity. Many participants deplored the fact that in grasslands where carbon stocks are the focus, management interventions that favour carbon stock enhancement put natural grassland ecosystems at risk.
Theme 2: Confounding plantations with forests
Across all focus groups many participants expressed concerns about the lack of distinction between a forest and a plantation: the so-called ‘forest definition question’. Participants feared that substituting oil-palm plantations for natural tropical rainforest damages biodiversity, as there are fewer species of birds and mammals in oil-palm plantations. However, on marginally fertile land, plantations can enhance biodiversity.
Theme 3: Adaptive management practices
In many focus groups participants discussed a variety of factors that can enhance carbon stocks in both grasslands and plantations while benefiting biodiversity and enhancing the people's well-being. Participants discussed unique conditions under which plantations can enhance biodiversity conservation, considered sustainable practices in grasslands, and explored land rights and tenure problems.
Discussion
The challenges and opportunities of carbon-farming in grasslands
Although most terrestrial biomass carbon is in trees, there is potential to sequester significant amounts of carbon in grasslands through appropriate grassland management (Conant, Reference Conant2010). A landscape governance approach to the REDD+ programme that goes beyond forests to encompass all landscapes would generate the desire to sequester carbon in non-forest ecosystems such as savannahs and other grasslands, which could lead to unacceptable conservation outcomes. Although biodiversity conservation has been addressed mainly in a landscape setting since the early 1980s (Noss, Reference Noss1983), participants across all focus groups agreed that delivering REDD+ climate action through a landscape approach could be problematic for biodiversity conservation in grasslands. For example, when carbon stock becomes the focus in low-carbon-density landscapes, such as the eastern African grasslands, which support some of the greatest diversity of protected species, the impact in terms of patterns and consequences of changes in biodiversity could be enormous (Putz & Redford, Reference Putz and Redford2009). Recipient governments are likely to promote grassland carbon-farming, which would encourage carbon-enhancing activities such as fire suppression to increase grass and soil carbon, fertilization (using nitrogenous fertilizers and composting) to spur grass growth and soil formation, and irrigation to counter high evapotranspiration rates. Patterns and consequences of changes in biodiversity resulting from such perturbations have been well documented (Table 1), particularly in relation to species diversity through knowledge of species traits such as richness, evenness, composition and interactions, and of ecosystem functioning through responses such as resilience and resistance to environmental change (Chapin et al., Reference Chapin, Zavaleta, Eviner, Naylor, Vitousek and Reynolds2000).
Although participants across all focus groups agreed that adopting a landscape governance approach to emissions reduction in grasslands would be detrimental to biodiversity, participants in some groups argued that it could also act as a strong incentive for recipient governments to develop and enforce climate resilience and climate change adaptation policies based on grassland management practices. Management practices such as rotational grazing systems, sustainable stocking rates, mixed stocking (cattle, horses and sheep/goats), grazing season planning (anticipating when and how much it will rain), and use of fire–grazing interactions tend to make systems more resilient to climate variation and climate change (O'Connor et al., Reference O'Connor, Kuyler, Kirkman and Corcoran2010). With more than 2 billion people inhabiting the world's grasslands and depending on them for their livelihoods (Conant, Reference Conant2010), some participants contended that requiring comprehensive grassland climate resilience and climate change adaptive management policies under a landscape governance approach to the REDD+ programme could encourage both national governments and grassland communities to reach general agreement on major land-use issues such as land rights, clarification of tenure and carbon ownership, and the need for negotiations with stakeholders. These participants argued that under a landscape governance approach both national governments and grassland communities would seek to maximize the carbon market value of grasslands, as payments would be performance-based.
Carbon-farming in plantations: the forest definition problem
The forest definition problem, which was at the centre of negotiations to incorporate forests into the global climate action plan prior to the Paris Agreement, could be exacerbated by a post-Paris Agreement adoption of a landscape governance approach to REDD+. The definition of forest has never been clear. The inconsistent elements of the etymology and power politics of resource use in medieval England indicate that the definition of forest has always been perceived by stakeholders in different ways (Putz & Redford, Reference Putz and Redford2010). For example, the forestry profession's definition of forest emphasizes instrumental/utilitarian value (Helms, Reference Helms2002), in contrast with the environmentalist definition, which emphasizes preservation (Putz & Redford, Reference Putz and Redford2010). The definition of forest used by the United Nations Framework Convention on Climate Change emphasizes land area (at least 0.05–1 ha), canopy cover (10–30% threshold) and height (minimum of 2–5 m; UNFCCC, 2002), which further broadens these discrepancies as it allows every country to define ‘forest’ to meet its objectives as long as it falls within these ranges.
The current conflicting wishes of stakeholders are at the centre of the controversial discussion over whether or not to grant plantations equal standing with natural forests. Throughout all focus groups participants affirmed that the development of plantations affects biodiversity conservation and poses serious ecological problems for natural forests, as plantations are sustained by intensive management practices (clear cutting, tree rotation, pesticide application and other agro-engineering practices; Bhagwat et al., Reference Bhagwat, Willis, Birks and Whittaker2008), which are at odds with characteristics of natural forests and conservation. For instance, clear cutting often takes place before plantations are established in tropical regions, which not only have the biophysical conditions most conducive for growing cash-crops but are also the most conducive for the growth of rainforests.
Many tropical forest-rich countries are therefore engaged in clear-cutting of their rainforests to establish plantations. In Malaysia and Indonesia, for instance, two of the world's biggest producers of palm oil, 9 million ha of tropical rainforests were clear-cut during 1975–2005 (Wicke et al., Reference Wicke, Sikkema, Dornburg and Faaij2011). The rainforests of Malaysia and Indonesia are among the world's biodiversity hotspots (UNEP-WCMC, 2004), and more clear-cutting of these countries’ rainforests to make way for oil-palm plantations under a landscape governance approach could be catastrophic to the cause of biodiversity conservation.
Many participants insisted that adopting a landscape governance approach to the REDD+ programme could precipitate expansion of oil-palm plantations, as the approach may overlook the forest definition question, which is an active issue at national level in many countries (e.g. Indonesia; Romijn et al., Reference Romijn, Ainembabazi, Wijaya, Herold, Angelsen, Verchot and Murdiyarso2013). A landscape governance approach would render the forest definition debate meaningless, as plantations would automatically fall within the scope of the broader landscapes approach, thus allowing plantation developers to benefit from carbon credits at the expense of natural forests and the biodiversity they preserve.
Despite the known negative effects of plantations and their management practices on biodiversity, some research has indicated that plantations can contribute to biodiversity conservation (Hartley, Reference Hartley2002). This is especially true in cases where plantations established in areas of heavily degraded natural forest ‘help restore native biota to degraded sites…by stabilizing soil and creating site conditions favourable for native animals and plants to recolonize’ (Hartley, Reference Hartley2002, p. 82). Although all focus groups agreed that plantations have potential to conserve biodiversity, many participants argued that this was possible only in specific conditions, such as in degraded forests. Adopting a landscape governance approach to the REDD+ programme could provide opportunity for recipient governments to develop and enforce land-use policies that encourage the use of heavily degraded lands for plantation cultivation. However, such policies would need to be approached with caution given that secondary logged natural forests, which are often considered to be degraded, can in some cases still preserve natural forest biodiversity, as they are used by species of high conservation value (Maddox, Reference Maddox2007).
These potential challenges and opportunities of the proposed landscape governance approach for the REDD+ programme (Fig. 1) suggest that policy makers and other stakeholders need to give full consideration to the various outcomes of the approach, so as to articulate their positions on REDD+ and make appropriate choices in the post-Paris Agreement era.
Conclusions
Given the potential challenges and opportunities presented by a landscape governance approach to the REDD+ programme, policy makers and stakeholders will need to assess carefully the potential outcomes of adopting the approach. The way forward is to look for strategies to maximize the opportunities and minimize the challenges associated with the approach. The new United Nations Sustainable Development Goals (UN-SDG Summit, 2015) provide two important avenues for this to be accomplished: ‘Responsible consumption and production’ (Goal 12), and ‘Protect, restore, and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss’ (Goal 15). National governments could embark on attaining these goals by focusing on developing strategies by which grassland landscape managers and plantation developers can enhance productivity through sustainable practices; for example, by limiting new plantations to already deforested or degraded lands (to strengthen socio-ecological and cultural capacity), and by making environmental assessment a mandatory condition for the establishment of plantations on degraded lands (to determine the presence or absence of high conservation values; i.e. ecological planning). Similarly governments could encourage grassland communities to adopt sustainable grassland management practices that can simultaneously enhance carbon sequestration and the biodiversity potential of grasslands, by investing in education, research and technical assistance programmes to help communities prioritize the long-term productivity of their land over short-term gains from carbon-farming alone (Conant, Reference Conant2010).
