Agro-ecosystem based sustainability indicators for climate resilient agriculture in India: A conceptual framework
Ecological Indicators (2019). Original Research. Policy Brief.
https://doi.org/10.1016/j.ecolind.2018.06.038Abstract
The impending threats of changing climate have been well documented across sectors. The climate risks are best addressed through increasing adaptive capacity and building resilience. Ever since the global call during the Rio Summit in 1992 for establishing sustainability indicators across sectors, there have been several studies across the world on developing indicators for sustainability, vulnerability and climate resilience. Agriculture, the most vulnerable system to changing climate, depends on the resilience of both social and ecological systems. This paper focuses on integrating the variability of climate into the agricultural sustainability measurement with a broad base of indicators and bringing in the localized factors for representing the agroecosystem specificities. The paper also aims at identifying indicators for measuring climate resilient agriculture in Indian sub-continent and developing a conceptual framework for profiling the spatial resilience across various agro-ecosystems for appropriate location-specific policy interventions. In the current study 1209 indicators used in various research studies were screened, grouped for similarity and purpose and classified based on the various dimensions viz., social, economic, ecological, etc. After a critical review based on their appropriateness as a measurable indicator, extent of overlap, relevance in Indian context and possible data availability, 41 indicators were shortlisted for validation through a comprehensive structured online survey among subject matter specialists (n = 225). The responses from the experts (n = 36) were analysed using weighted sum model (WSM) and analytic hierarchy process (AHP). The study identifies a list of 30 sustainability indicators for climate resilient agriculture in India, that are particularly suitable for different agro-ecosystems of the sub-continent. The authors advocate an action-oriented model called Climate Risk Management Package for Agriculture (CRiMPA) to aid in planning spatial/agro-ecosystem specific interventions, which in turn could strengthen the National Action Plan for Climate Change (NAPCC) of Government of India.

The magnitude and pace of global change demand rapid assessment of nature and its contributions to people. We present a fine-scale global modeling of current status and future scenarios for several contributions: water quality regulation, coastal risk reduction, and crop pollination. We find that where people’s needs for nature are now greatest, nature’s ability to meet those needs is declining. Up to 5 billion people face higher water pollution and insufficient pollination for nutrition under future scenarios of land use and climate change, particularly in Africa and South Asia. Hundreds of millions of people face heightened coastal risk across Africa, Eurasia, and the Americas. Continued loss of nature poses severe threats, yet these can be reduced 3- to 10-fold under a sustainable development scenario

Earth is approaching environmental thresholds that, if crossed, will create serious disruptions to ecosystems, economies, and society. To avoid the devastating effects of climate change and biodiversity loss, humanity must protect and restore native ecosystems. International conventions and organizations support forest restoration as a method for mitigating hazardous environmental shifts, but questions remain as to where and how to focus such restoration efforts. On page 76 of this issue, Bastin et al. describe a new approach that advances our understanding of global tree distribution.

https://doi.org/10.1111/gcb.14856Abstract
Climate change poses significant emerging risks to biodiversity, ecosystem function and associated socioecological systems. Adaptation responses must be initiated in parallel with mitigation efforts, but resources are limited. As climate risks are not distributed equally across taxa, ecosystems and processes, strategic prioritization of research that addresses stakeholder‐relevant knowledge gaps will accelerate effective uptake into adaptation policy and management action. After a decade of climate change adaptation research within the Australian National Climate Change Adaptation Research Facility, we synthesize the National Adaptation Research Plans for marine, terrestrial and freshwater ecosystems. We identify the key, globally relevant priorities for ongoing research relevant to informing adaptation policy and environmental management aimed at maximizing the resilience of natural ecosystems to climate change. Informed by both global literature and an extensive stakeholder consultation across all ecosystems, sectors and regions in Australia, involving thousands of participants, we suggest 18 priority research topics based on their significance, urgency, technical and economic feasibility, existing knowledge gaps and potential for cobenefits across multiple sectors. These research priorities provide a unified guide for policymakers, funding organizations and researchers to strategically direct resources, maximize stakeholder uptake of resulting knowledge and minimize the impacts of climate change on natural ecosystems. Given the pace of climate change, it is imperative that we inform and accelerate adaptation progress in all regions around the world.

The impacts of climate change and the socioecological challenges they present are ubiquitous and increasingly severe. Practical efforts to operationalize climate-responsive design and management in the global network of marine protected areas (MPAs) are required to ensure long-term effectiveness for safeguarding marine biodiversity and ecosystem services. Here, we review progress in integrating climate change adaptation into MPA design and management and provide eight recommendations to expedite this process. Climate-smart management objectives should become the default for all protected areas, and made into an explicit international policy target. Furthermore, incentives to use more dynamic management tools would increase the climate change responsiveness of the MPA network as a whole. Given ongoing negotiations on international conservation targets, now is the ideal time to proactively reform management of the global seascape for the dynamic climate-biodiversity reality.

https://doi.org/10.1038/s41893-019-0412-1Abstract
Regional and global assessments periodically update what we know, and highlight what remains to be known, about the link- ages between people and nature that both define and depend upon the state of the environment. To guide research that better informs policy and practice, we systematically synthesize knowledge gaps from recent assessments of four regions of the globe and three key themes by the Intergovernmental Science-Policy Platform for Biodiversity and Ecosystem Services. We assess their relevance to global sustainability goals and trace their evolution relative to those identified in the Millennium Ecosystem Assessment. We found that global sustainability goals cannot be achieved without improved knowledge on feedbacks between social and ecological systems, effectiveness of governance systems and the influence of institutions on the social distribution of ecosystem services. These top research priorities have persisted for the 14 years since the Millennium Ecosystem Assessment. Our analysis also reveals limited understanding of the role of indigenous and local knowledge in sustaining nature’s benefits to people. Our findings contribute to a policy-relevant and solution-oriented agenda for global, long-term social-ecological research.

Forest Ecology and Management (2019). Systematic Review.
https://doi.org/10.1016/j.foreco.2018.11.033Abstract
Several Andean countries have planned to restore forest cover in degraded land to enhance the provision of multiple ecosystem services in response to international commitments such as the Bonn Challenge. Hydrological services, e.g. water supply, hydrological regulation and erosion mitigation, are particularly important to sustain the life of more than fifty million Andean people. While rapid and important forest cover changes have occurred during recent decades, critical information on the impact of forestation on hydrological services has not yet been synthesized in the context of Andean ecosystems. We define forestation as the establishment of forest by plantation or natural regeneration on areas that either had forest in the past or not. To help improve decision-making on forestation in the Andes, we reviewed the available literature concerning the impacts of forestation on water supply, hydrological regulation and mitigation of erosion and landslides. We also examined available data on the most relevant hydrological processes such as infiltration, evapotranspiration and runoff in forest stands. Hydrological services from native forests were also included as a reference state for comparing processes and services provided by forestation. Following systematic review protocols, we synthesized 155 studies using different methods, including meta-analyses and meta-regressions. Results show that forestation has had clear impacts on degraded soils, through reducing water erosion of soils and risk of moderate floods, increasing soil infiltration rate by 8 and topsoil organic matter (SOM). We found that 20 years of tree plantation was sufficient to recover infiltration rate and sediment yield close to the levels of native forests whereas SOM, soil water storage and surface runoff of native forests could not be recovered by forestation in the time scales examined. The benefits in terms of hydrological regulation are at the expense of a reduction in total water supply since forest cover was associated with higher water use in most Andean regions. Forestation with native species was underrepresented in the reviewed studies. The impact of forestation on landslides has also been largely overlooked in the Andes. At high elevations, exotic tree plantations on Andean grasslands (e.g. páramo and puna) had the most detrimental consequences since these grasslands showed an excellent capacity for hydrological regulation and erosion mitigation but also a water yield up to 40% higher than tree plantations. People engaged in forest restoration initiative should be aware that hydrological services may take some time for society and the environment to show clear benefits after forestation.

https://doi.org/10.1038/s41558-019-0615-5Abstract
Land-use change disturbs the function of peatland as a natural carbon sink and triggers high GHG emissions. Nevertheless, historical trends and future trajectories of GHG budgets from soil do not explicitly include peatlands. Here, we provide an estimate of the past and future role of global peatlands as either a source or sink of GHGs based on scenario timelines of land conversion. Between 1850 and 2015, temperate and boreal regions lost 26.7 million ha, and tropical regions 24.7 million ha, of natural peatland. By 2100, peatland conversion in tropical regions might increase to 36.3 million ha. Cumulative emissions from drained sites reached 80 ± 20 PgCO2e in 2015 and will add up to 249 ± 38 Pg by 2100. At the same time, the number of intact sites accumulating peat will decline. In 1960 the global peatland biome turned from a net sink into a net source of soil-derived GHGs. Annual back-conversion of most of the drained area would render peatlands GHG neutral, whereas emissions from peatland may comprise 12–41% of the GHG emission budget for keeping global warming below +1.5 to +2 °C without rehabilitation.

https://doi.org/10.1111/gcb.14815Abstract
There is growing international interest in better managing soils to increase soil organic carbon (SOC) content to contribute to climate change mitigation, to enhance resilience to climate change and to underpin food security, through initiatives such as international ‘4p1000’ initiative and the FAO’s Global assessment of SOC sequestration potential (GSOCseq) programme. Since SOC content of soils cannot be easily measured, a key barrier to implementing programmes to increase SOC at large scale, is the need for credible and reliable measurement/monitoring, reporting and verification (MRV) platforms, both for national reporting and for emissions trading. Without such platforms, investments could be considered risky. In this paper, we review methods and challenges of measuring SOC change directly in soils, before examining some recent novel developments that show promise for quantifying SOC. We describe how repeat soil surveys are used to estimate changes in SOC over time, and how long‐term experiments and space‐for‐time substitution sites can serve as sources of knowledge and can be used to test models, and as potential benchmark sites in global frameworks to estimate SOC change. We briefly consider models that can be used to simulate and project change in SOC and examine the MRV platforms for SOC change already in use in various countries/regions. In the final section, we bring together the various components described in this review, to describe a new vision for a global framework for MRV of SOC change, to support national and international initiatives seeking to effect change in the way we manage our soils.

https://doi.org/10.1016/j.landusepol.2019.104302Abstract
Nature-based solutions (NbS) is the latest contribution to the green concept family. NbS is defined as actions based in nature addressing societal challenges. In this study, we lean on the concept boundary object, broken down into three analytical categories: use, core ideas and granularities, to explore the cohesive and fragmenting powers of the NbS concept, and discuss its future role in green space governance. The study is based on a structured, qualitative review of 112 scientific peer-reviewed publications that use the term NbS. Most publications are from 2017 or later, highlighting the novelty of the NbS concept. The concept has a strong footing in the European urban context. Flood mitigation and functional ecosystems and biodiversity conservation are the most targeted sustainability goals in the publications, and a diversity of solutions are considered. There is a close link between the NbS concept, green infrastructure, and the ecosystem service concept, indicating a path dependency in its uptake and use. The publications demonstrate a low level of integration of the NbS concept (i.e. it is commonly used as a buzz word). Most empirical studies focus solely on environmental benefits delivered by NbS, and few studies assess social, economic, and environmental benefits together, which is a central ambition of the concept. We conclude that the NbS concept is working on the boundaries between different scientific disciplines and between science and policy. Depending on how the research community deals with identified temporal, epistemological and ontological granularities, we conclude that the concept has three potential developmental pathways; broader and deeper, biased with stickiness to older green concepts and an empty buzz word.

Journal of Applied Ecology (2019). Original Research.
https://doi.org/10.1111/1365-2664.13559Abstract
Ecosystem‐based adaptation (EbA) relies upon the capacity of ecosystems to buffer communities against the adverse impacts of climate change. Maintaining ecosystems that deliver critical services to communities can also provide co‐benefits beyond adaptation, such as climate mitigation and protection of biological diversity and livelihoods. EbA has to a limited extent drawn upon indigenous‐and local knowledge (ILK) for defining critical services and for implementing EbA in decision‐making. This is a paradox given that the primary focus of EbA is to enable communities to adapt to climate change. The purpose of this study was to elucidate EbA strategies that take into account the knowledge of Sámi reindeer herders about pastures in tundra regions. We first examined what constitutes critical services through a synthesis of data and literature. We thereafter used content analysis of 91 land use cases from 2010–2018 to investigate to what extent the herders’ knowledge and maps over seasonal pastures and migratory routes are used in local decision‐making. Finally, we propose EbA strategies of relevance to Sámi communities and pastoral communities elsewhere. Our analysis revealed that reindeer herders and organizations representing their interests perceived threats from green energy development, tourism, recreation, public road construction and powerlines. These threats included the loss of key habitats and the loss of connectivity for migration between seasonal pastures. Pastoralists’ knowledge is incorporated through participatory tools to protect the ecosystems and services crucial for pastoralists, but multiple competing land uses result in incremental loss of pastures regardless. Synthesis and application. Protecting pasture ecosystems and the services they deliver, including the connectivity between pastures, are necessary EbA strategies to buffer the adverse effects of climate change. Drawing on pastoralists’ knowledge to elicit EbA strategies can inform decision‐making, but it is equally important to implement this knowledge for prioritizing adaptation needs in the assessment of competing land use.

https://doi.org/10.1016/j.eist.2019.09.005Abstract
Transitions literature regards technologies as critical components in shifting systems towards sustainability, which has informed the development of the technology-oriented Technological Innovation System (TIS) framework. The emerging discourse on nature-based solutions (NBS) – multifunctional nature-integrated spatial planning and design innovations – raises the question to what extent TIS can account for the development and diffusion of NBS. Following a literature review, we present the Nature-Based Innovation System (NBIS) framework delineating critical factors for urban nature-based innovation. We find both commonalities and differences between TIS and NBIS, suggesting that the roles of place-based dynamics, agency and governance structure are more central to nature-based innovation, and market formation is more central to technological innovation. This has implications for the study of sustainability transitions, which has likely underplayed the potential of innovations at the nexus of socio-technical and socio-ecological systems. Future research is needed to refine the NBIS framework, for example by studying evolutionary developmental trajectories.

Seagrass meadows are an important wetland habitat that have been degraded globally but have an important carbon storage role. In order to expand the restoration of these productive and biodiverse habitats methods are required that can be used for large scale habitat creation across a range of environmental conditions. The spreading of seagrass seeds has been proven to be a successful method for restoring seagrass around the world, however in places where tidal range is large such methods become limited by resultant water movements. Here we describe and test a method for deploying seagrass seeds of the species Zostera marina over large scales using a new, simple method “Bags of Seagrass Seeds Line (BoSSLine).” This method involved planting seeds and sediment using natural fiber hessian bags deployed along strings anchored onto the seabed. When deployed in a suitable environment 94% of bags developed mature seagrass shoots, unfortunately one site subjected to a large storm event resulted in sediment burial of the bags and no seed germination. Bags were filled with 100 seeds with each leading to the development of 2.37 ± 2.41 mature shoots (206 ± 87 mm in length) 10 months after planting. The method was proven successful however the experiments illustrated the need to ensure habitat suitability prior to their use. Low seed success rate was comparable to other restoration studies, however further trials are recommended to ensure ways to improve this rate. In conclusion, this study provides evidence for an effective, simple method “Bags of Seagrass Seeds Line (BoSSLine)” for deploying seeds of the seagrass Zostera marina over large scales.

Global Change Biology (2019). Original Research.
https://doi.org/10.1111/gcb.14887Abstract
Afforestation is considered a cost‐effective and readily available climate change mitigation option. In recent studies afforestation is presented as a major solution to limit climate change. However, estimates of afforestation potential vary widely. Moreover, the risks in global mitigation policy and the negative trade‐offs with food security are often not considered. Here we present a new approach to assess the economic potential of afforestation with the IMAGE 3.0 integrated assessment model framework. In addition, we discuss the role of afforestation in mitigation pathways and the effects of afforestation on the food system under increasingly ambitious climate targets. We show that afforestation has a mitigation potential of 4.9 GtCO2/year at 200 US$/tCO2 in 2050 leading to large‐scale application in an SSP2 scenario aiming for 2°C (410 GtCO2 cumulative up to 2100). Afforestation reduces the overall costs of mitigation policy. However, it may lead to lower mitigation ambition and lock‐in situations in other sectors. Moreover, it bears risks to implementation and permanence as the negative emissions are increasingly located in regions with high investment risks and weak governance, for example in Sub‐Saharan Africa. Afforestation also requires large amounts of land (up to 1,100 Mha) leading to large reductions in agricultural land. The increased competition for land could lead to higher food prices and an increased population at risk of hunger. Our results confirm that afforestation has substantial potential for mitigation. At the same time, we highlight that major risks and trade‐offs are involved. Pathways aiming to limit climate change to 2°C or even 1.5°C need to minimize these risks and trade‐offs in order to achieve mitigation sustainably.

https://doi.org/10.1007/s10457-018-0273-zAbstract
In recent years, there has been a growing realization that improving market access for smallholders will lead to improvement in income and food security. However, market failure often limit smallholders’ fair access to market opportunities. To address this problem, a market-oriented agroforestry action research program was implemented in six sites of Kavre and Lamjung districts of Nepal between 2013 and 2016. The main objective of this paper is to investigate the changing impacts of the market-oriented agroforestry system on improving people’s livelihoods and addressing food security issues. The net-margin analysis of five priority products of agroforestry systems indicated that farmers benefitted most by a banana-based high yielding fodder system (56%) followed by Alnus-cardamom system (48%), tomato-fodder and buffalo (36%), chilli-fodder (26%) and ginger-based (25%) systems due to facilitation of market-oriented agroforestry action research services. The impact of market-oriented agroforestry intervention from a survey of 289 households, revealed that household income was increased by 37–48%, which can provide up to six additional months of food to the poorest households. This innovation has the potential to take the majority of households (63%) out of the poverty cycle while avoiding food shortage during the year. The implications of the study are that farmers must be united for collective marketing of their production and develop marketing strategies to eliminate middle men for better return. Some key lessons learned for the success of this research include farmers’ own motivation, favorable environment, and the inclusion of social activities and incentives for cultivating priority products species.
