The COVID-19 pandemic has had a global impact on the tourism sector. With tourism numbers dramatically reduced, millions of jobs could be lost, and progress made in equality and sustainable economic growth could be rolled back. Widespread reports of dramatic changes to protected and conserved1 area visitation have negative consequences for conservation finances, tourism businesses and the livelihoods of people who supply labour, goods and services to tourists and tourism businesses. This paper aims to share experiences from around the world on the impacts of the COVID-19 pandemic on protected area tourism; and considers how to build resilience within protected area tourism as a regenerative conservation tool.

The expansion of oil palm plantation has caused adverse impacts on the ecosystem. It has been associated with deforestation, biodiversity loss, disturbances to environmental services and livelihood change. The government of Indonesia has made an effort to control the negative effects by issuing relevant policies. One of the policies is Indonesian Sustainable Palm Oil (ISPO)’s sustainability standards to which large-scale plantations and smallholders are obliged to adhere. This study assesses the readiness of two types of smallholders, namely, the nucleus–plasma scheme and independent smallholders to adopt ISPO standards. Using a case study research approach in two oil palm plantation villages in East Kalimantan, the study found out a number of ISPO implementation challenges, grouped into structural and socio-cultural challenges, which make smallholders less ready to adhere to this mandatory policy. Coping with these challenges, this study proposed that land and business legality programs be expedited to strengthen property rights, and that training and education programs be intensified to enhance awareness, knowledge and capacity of smallholders to enable them to comply with sustainability standards.

Over the last decade, there have been increasing calls for robust impact evaluations of voluntary agricultural sustainability standards (VSS’s). In response, this study reviews the literature regarding 13 major agricultural standards, asking: where are certified crops being studied? Which sustainability outcomes and indicators are measured? And finally, what does the current evidence base suggest about VSS outcomes? The analysis of 45 peer-reviewed articles suggests a mismatch between what is certified and what is studied. Some crops and standards are over-represented in the literature as compared to their amount of certified production (e.g. coffee and Fairtrade certification), while others are under-represented (cotton, sugar, cocoa, soy, and palm oil, in addition to Organic certification). The review also identifies countries which appear to be under-represented in the literature, including Brazil, Australia, Malaysia, the Ivory Coast, and the United States. When measuring success, economic indicators are the most frequently evaluated, and only 20% of studies analyze economic, social, and environmental indicators simultaneously. When grouped by case, the indicator results tend to be positive on average (51%), followed by no difference (41%) and negative (8%) outcomes. There are no significant differences among sustainability pillars in terms of the average proportion of positive and negative results. These findings should be interpreted carefully, since the evidence base is heavily weighted towards coffee certification (75% of cases analyzed), and impacts are highly context dependent. Finally, the review identifies best practices in conducting robust evaluations, including the importance of addressing sustainability trade-offs and appropriately measuring environmental outcomes. While significant gaps remain, the findings indicate an increase in research credibly measuring VSS impacts.

The Orinoco river basin is the third largest river in the world by volume. Its catchment encompasses 27 major sub-basins including the Bita with a catchment area of about 825,000 ha, which originates in the Colombian high plains in the Llanos ecoregion. It has been recognized as a priority area for conservation through different gap analyses and overall determined to have good health according to the Orinoco report card 2016. The natural climate and hydrologic processes, and their synergies with flooded forests, savannas, wetlands, species diversity and local economic activities, are part of a dynamic and sensitive system. With the purpose of conserving the ecological, social and cultural benefits that it brings, the Colombian Government, with the support of regional and local civil society organizations, promoted the designation of a conservation area. Technical exercises were carried out including biological and socioeconomic surveys, local stakeholder consultations and future scenario modeling. In June 2018, the Bita River basin was designated as the largest Ramsar site in Colombia, providing a worldwide example of explicit protection of riverine systems. In order to maintain this free-flowing river, land use and fisheries management, in conjunction with other conservation actions, are being implemented and provide a model of protection for freshwater ecosystems that could be replicated elsewhere.

The continued growth in demand for a relatively small number of agricultural and forest commodities in global trade has placed increasing pressures on forests across landscapes in the tropics and sub-tropics. These pressures are amplified by growing domestic demand in producing countries. Such trends have led to multiple environmental challenges linked to loss of forests and biodiversity and rising carbon emissions. They also create social challenges including threats to local food security, tenure rights and the livelihoods of indigenous peoples and local communities. Expansion of trade in forest-risk commodities over the past three decades has resulted in increased pressure from civil society organizations, consumers, international banks and shareholders of consumer goods companies to develop and implement a diverse array of instruments and tools to promote sustainable or deforestation-free sourcing, and as a way to reduce exposure to reputational, financial and regulatory risks. Multi-stakeholder platforms and commodity roundtables also emerged, in response to criticisms of government failures. The multiplication of sustainability initiatives has been driven by the growing complexity and diversity of conditions under which agri-food and timber supply chains operate. Private sector actors have increasingly defined and monitored their own sustainability performance by using certification standards or by developing their own procedures and criteria. More recently, a discernible shift toward landscape or jurisdictional approaches is seen as a way to meet sustainability goals. The growing complexity of policy regimes, inevitably, results in ambiguities and can lead to tradeoffs between gains and losses. This review presents a synthesis of the multiple public, private and hybrid governance initiatives that aim to promote sustainable supplies of key forest-risk commodities. It aims to make it easier to understand a vast and rapidly expanding literature. By drawing on the published literature and scientific discussions, including the recent FTA 2020 Science Conference, the review highlights some of the outstanding challenges that urgently need to be addressed in order to achieve the targeted impacts.

Grassland-dependent Vulpes velox Say (Swift Foxes) occupy only a portion of their historical range in the North American Great Plains and remaining subpopulations are functionally disconnected due to habitat fragmentation and other barriers. Modeling habitat suitability is critical to identifying sites for habitat conservation and reintroduction and increasing subpopulation connectivity. We used mixed-effects modeling to simultaneously evaluate Swift Fox presence against habitat variables and subecoregional location. Our results show that habitat suitability is dependent on geographic location. Individual subecoregional models were each influenced by land cover and soil composition but varied by dominant soil component and correlation with surrounding land uses. These findings prioritize localized data for species management and predict how changing landscape composition may impact Swift Fox distribution.

Quantifying ecological condition, notably the extent of forest degradation is important for understanding and designing measures to protect biodiversity and enhancing the capacity of forests to deliver ecosystem services. Conservation planning, particularly the prioritization of management interventions for forests, is often lacking spatial data on forest degradation, and it is often overlooked within decision-making processes. We develop a continuous metric termed Forest Condition (FC) which aims to measure the degree of forest degradation on a scale from 0 to 100, incorporating the temporal history of forest change over any spatial extent. We parameterize this metric based on estimated changes in above ground biomass in the context of forest fragmentation over time to estimate a continuous measure of forest degradation for Congo Basin countries. We estimate that just <70% of Congo Basin forests remain fully intact, a decrease from 78% in the year 2000. FC was validated by direct remote sensing measurements from Landsat imagery for DRC. Results showed that FC was significantly positively correlated with forest canopy cover, gap area per hectare, and magnitude of temporal change in Normalized Burn Ratio. We tested the ability of FC to distinguish primary and secondary degradation and deforestation and found significant differences in gap area and spectral anomalies to validate our theoretical model. We apply the IUCN Red List of Ecosystems criteria to demonstrate the integration of forest condition to assess the risk of ecosystem collapse. Based on this assessment, we found that without including FC in the assessment of biotic disruption, 12 ecosystems representing over 11% of forested area in 2015 would not have been assigned a threat status, and an additional 9 ecosystems would have a lower threat status. Our overall assessment of ecosystems found about half of all Congo Basin ecosystem types, accounting for 20% of all forest area are threatened to some degree, including 4 ecosystems (<1% of total area) which are critically engendered. FC is a transferrable and scalable assessment to support forest monitoring, planning, and management.

Whale-ship collisions represent a threat to some whale population survival. The shipping industry rarely adopts solutions to reduce the risk of collisions. This lack of compliance is partly due to the fact that previous work has failed to assess the economic and logistic constraints these solutions put on the shipping industry. Our work explored for the first time the logistical considerations affecting the adoption of whale-ship collision avoidance approaches by shipping companies. We used a choice experiment approach to assess the shipping industry’s preferences for mitigation solutions, by questioning ship crews. Amongst other things, our results demonstrated a preference for avoiding a high-density whale area instead of reducing speed in it, and a requirement for upstream information to plan the journey depending on these areas. Our findings could be used as guidelines for the implementation of mitigation solutions depending on situational characteristics (e.g., travel distance, area’s size) and provide insights for policy-making to reduce the risk of whale-ship collisions.

Enteric methane emissions are the single largest source of direct greenhouse gas emissions (GHG) in beef and dairy value chains and a substantial contributor to anthropogenic methane emissions globally. In late 2019, the World Wildlife Fund (WWF), the Advanced Research Projects Agency-Energy (ARPA-E) and the Foundation for Food and Agriculture Research (FFAR) convened approximately 50 stakeholders representing research and production of seaweeds, animal feeds, dairy cattle, and beef and dairy foods to discuss challenges and opportunities associated with the use of seaweed-based ingredients to reduce enteric methane emissions. This Perspective article describes the considerations identified by the workshop participants and suggests next steps for the further development and evaluation of seaweed-based feed ingredients as enteric methane mitigants. Although numerous compounds derived from sources other than seaweed have been identified as having enteric methane mitigation potential, these mitigants are outside the scope of this article.

Reducing deforestation and forest degradation presents a climate-change mitigation opportunity that is critical to meeting the Paris Agreement goals, and to achieving reductions in the atmospheric concentrations of greenhouse gases (GHGs). Reducing Emissions from Deforestation and Forest Degradation (REDD) provides developing countries with results-based financial incentives for reducing deforestation and forest degradation through either non-market payments (payments without generation of carbon credits), or market-based mechanisms (carbon credits). REDD credits have been recently accepted to be used in offsetting programs (e.g., CORSIA) and are being considered under Article 6. However, various publications have questioned whether carbon credits from REDD should be accepted under market-based mechanisms, and have identified issues regarding their environmental integrity and their ability to offset emissions from other sectors. In recent years, REDD implementation has moved from the project level to the national or subnational (jurisdictional) level, and is addressing some of the concerns that have been raised for project-level interventions regarding the robustness of baselines and leakage, for example. In this paper we compare the environmental integrity of credits from REDD programs with that from on-grid renewable energy projects by examining aspects related to permanence, additionality, baselines, uncertainty, and leakage. We show that the environmental integrity of emission reductions sourced from REDD programs has unique strengths, and that those sourced from renewable energy projects have weaknesses of their own. Probably due to a lack of understanding of the respective weaknesses and strengths of these two sources of credits, the emission reductions from REDD programs have been historically questioned and subjected to a level of scrutiny that has not been made with emission reductions from other sectors, such as renewable energy projects. Recognizing the strengths and weaknesses of emission reductions from both types should help decision makers and carbon standards recognize the high quality of emission reductions from REDD programs, and rationalize the current requirements or restrictions imposed.
