The success of the Sustainable Development Goals (SDGs) depends on solving the 'nexus' challenge: how can positive interactions between SDGs be optimised, and negative interactions minimised, in order to create co-benefits and reduce trade-offs? Due to their varying impacts on the SDGs, the economic activities undertaken by organisations present a key lever for operationalising this SDG-nexus. Yet the interactions between individual economic activities and the economic, social, and environmental dimensions of sustainable development have not been systematically assessed, thus creating a vital operational bottleneck to achieving the SDGs. This paper conducts a systematic review of 876 articles published between 2005 and 2019 to study the nexus between individual economic activities, sustainable development in general, and the SDGs in specific. It finds that studies on agricultural, industrial, and manufacturing activities predominantly report negative impacts on environmental development, while literature on services activities highlight economic and social contributions. Overall, most economic activities are expected to positively impact industrialization, infrastructure, and innovation [SDG 9] and economic productivity [SDG 8], while many help meet basic needs [SDGs 2, 3, 4, 6, 7, 11]. However, negative impacts are widespread, afflicting ecosystems [SDGs 14 and 15], climate change [SDG 13] and human health [SDG 3]. We synthesise positive and negative interactions between individual economic activities and SDG targets and discuss implications for: integrated (nexus) governance approaches to the SDGs; the role of the private sector in promoting sustainable development; and for improving statistical classifications to monitor economic activities' SDG impacts.

“…Peruvian small-scale fishing effort was reconstructed following the Sea Around Us fisheries data reconstruction framework (Zeller and Pauly, 2016), aiming to improve the local resolution of previous attempts that sought to estimate global fishing effort (Greer et al, 2019). This process included: identifying and sourcing official and alternative sources of time series data on the number of vessels in the Peruvian small-scale fleet and their characteristics; developing data 'anchor points' in time using all available information; interpolating data for the periods between anchor points; estimating small-scale fishing effort based on validated predictor variables; and constructing confidence intervals for the fishing effort reconstruction over time, by scoring uncertainty in data sources, assumptions and methods used (Zeller and Pauly, 2016;Greer et al, 2019).…”

“…Two indicators were used to estimate annual fishing effort: nominal and effective effort. Nominal effort in year t (nE t ) is the product of the number of boats in the fleet (N t ), their average capacity (P t ) and the average number of days they spend fishing during the year (D) (Greer et al, 2019).…”

“…The reported increases in fishing effort observed around the world (Anticamara et al, 2011;Greer et al, 2019) continue to raise concerns about the sustainability of the targeted resources and the wellbeing of peoples that depend on them for their livelihoods and nutrition (Watson et al, 2012;Link and Watson, 2019). Thus, this paper aims at reconstructing small-scale fishing effort in Peru, seeking to highlight the extent at which it has grown over time and assess its impact on the fishery's performance and fishers' economies.…”

Small-scale fisheries are globally marginalized by management institutions; thus, they have to endure the consequences of ineffective regulations, environmental uncertainty, social traps and market inequity. Small-scale fisheries in Peru, one of the world's leading fishing countries, are important contributors to national employment, food security and gross domestic product. Yet, relatively little is known about these fisheries and their evolution, except for the fact that the Peruvian small-scale fleet size is rapidly increasing. Here, we reconstructed small-scale fishing effort across time and developed several indicators using it to assess changes in the fleet's fishing efficiency and economic performance. Segmented regression analysis was used to identify statistically significant breakpoints and changes in their trajectories between 1950 and 2018. Our results suggest that fishing effort has strongly increased, and at much faster rates than the catches, particularly since 2006. The combined effect of these trends results in significant declines in the fleet's ratio indicators (i.e., catch per unit of effort, revenue per unit of effort, and fisher's incomes relative to Peru's minimum wage), suggesting that the growing fishing effort is unsustainable and uneconomic. The behavior of these indicators differs within the fleet, depending on the vessel's main fishing method. Most small-scale fishers are currently living in relative poverty. Yet, fishers using the least selective fishing gears, or engaged in illegal fishing, had the most stable incomes over the past decade. These findings are discussed in detail by exploring the social, legal and economic drivers fostering fleet growth. Finally, a list of general recommendations aimed at improving fisheries sustainability and fisher's wellbeing was produced, based on the local context, fisheries literature and common sense.

Carbon pricing and planetary boundaries

Human activities are threatening to push the Earth system beyond its planetary boundaries, risking catastrophic and irreversible global environmental change. Action is urgently needed, yet well-intentioned policies designed to reduce pressure on a single boundary can lead, through economic linkages, to aggravation of other pressures. In particular, the potential policy spillovers from an increase in the global carbon price onto other critical Earth system processes has received little attention to date. To this end, we explore the global environmental effects of pricing carbon, beyond its effect on carbon emissions. We find that the case for carbon pricing globally becomes even stronger in a multi-boundary world, since it can ameliorate many other planetary pressures. It does however exacerbate certain planetary pressures, largely by stimulating additional biofuel production. When carbon pricing is allied with a biofuel policy, however, it can alleviate all planetary pressures.
