Bradfer‐Lawrence, Tom; Finch, Tom; Bradbury, Richard B.; Buchanan, Graeme M.; Midgley, Andrew; Field, Rob H. (2021): The potential contribution of terrestrial nature‐based solutions to a national ‘net zero’ climate target. In J Appl Ecol 137 (3), p. 32. DOI: 10.1111/1365-2664.14003.

"Many national governments have incorporated nature-based solutions (NbS) in their plans to reduce net greenhouse gas emissions. However, uncertainties persist regarding both feasibility and consequences of major NbS deployment. Using the United Kingdom as a national-level case study, we examined the potential contribution of three terrestrial NbS: peatland restoration, saltmarsh creation and woodland creation."

"Many countries have adopted large-scale tree planting programmes as a climate mitigation strategy and to support local livelihoods. We evaluate a series of large-scale tree planting programmes using data collected from historical Landsat imagery in the state of Himachal Pradesh in Northern India. Using this panel dataset, we use an event study design to estimate the socioeconomic and biophysical impacts over decades of these programmes. We find that tree plantings have not, on average, increased the proportion of forest canopy cover and have modestly shifted forest composition away from the broadleaf varieties valued by local people. Further cross-sectional analysis, from a household livelihood survey, shows that tree planting supports little direct use by local people. We conclude that decades of expensive tree planting programmes in this region have not proved effective. This result suggests that large-scale tree planting may sometimes fail to achieve its climate mitigation and livelihood goals."

"Environmental geopolitics offers an analytical approach that considers how environmental themes are brought into the service of geopolitical agendas. Of particular concern are claims about environment-related security and risk and the justification of actions (or inactions) proposed to deal with those claims. Environmental geopolitical analysis focuses on geographical knowledge and how that knowledge is generated and applied to stabilize specific understandings of the world. Climate engineering is a realm in which certain kinds of geographical knowledge, in the form of scientific interpretations of environmental interactions, are utilized to support a selective agenda that, despite claims about benefiting people and environments on a global scale, may be shown to reinforce uneven relationships of power as well as patterns of injustice. This paper focuses on how the IPCC AR5 discusses and portrays climate engineering."
