Highlights: [•] Sixty-seven percent of surveyed vacant lots are used for public, private or commercial purposes. [•] Surveyed lots which are unused are largely located in areas of high population density and low income. [•] Sixty-two percent of surveyed vacant lots are covered by trees and other herbaceous vegetation. [•] Vegetated vacant lots are spatially clustered and correlated with neighborhood green space. [•] Fine-scale classification can support planning for vacant lot management and development. [ABSTRACT FROM AUTHOR]

Automated decision making and predictive analytics through artificial intelligence, in combination with rapid progress in technologies such as sensor technology and robotics are likely to change the way individuals, communities, governments and private actors perceive and respond to climate and ecological change. Methods based on various forms of artificial intelligence are already today being applied in a number of research fields related to climate change and environmental monitoring. Investments into applications of these technologies in agriculture, forestry and the extraction of marine resources also seem to be increasing rapidly. Despite a growing interest in, and deployment of AI-technologies in domains critical for sustainability, few have explored possible systemic risks in depth. This article offers a global overview of the progress of such technologies in sectors with high impact potential for sustainability like farming, forestry and the extraction of marine resources. We also identify possible systemic risks in these domains including a) algorithmic bias and allocative harms; b) unequal access and benefits; c) cascading failures and external disruptions, and d) trade-offs between efficiency and resilience. We explore these emerging risks, identify critical questions, and discuss the limitations of current governance mechanisms in addressing AI sustainability risks in these sectors. • There is a growing interest in AI-technologies for sustainability. • Increased uses of these technologies could create new types of systemic risks. • We show a global uptake of AI-technologies in farming, forestry and marine management. • We explore gaps in principles and governance of AI from a sustainability perspective.
