Rethinking the role of law in adapting to climate change

Abstract

The article evaluates the role of law in adaptation over the past decade. We track the emergence of international adaptation law within the climate and non‐climate regime, alongside increasingly dire extreme events and strident scientific consensus. Examining the growth in national and subnational laws for adaptation, we reflect on the role of framework legislation and legal mechanisms used in sectoral laws. Based on progress over the past decade, we outline how the role of law can be enhanced and accelerated in the decade ahead. We identify important trends in adaptation law and consider the potential for these innovations to drive future adaptation: the sheer growth in priority and volume of laws directed towards adaptation; the intersection of adaptation with other policy domains, especially disaster risk reduction; the need for improved architecture for funding adaptation; and the important role of strategic litigation. Largely absent from the past decade of adaptation law reform is evaluation of effectiveness, or examples of systemic reform that addresses underlying causes of vulnerability. With slow progress in implementing transformational adaptation law reform, we identify five design principles for adaptation laws. The design of laws must (1) be responsive to change; (2) address equity dimensions of climate change; (3) implement innovative solutions; (4) maximize co‐benefits; and (5) establish processes for managing trade‐offs.

Assisted migration and the rare endemic plant species: the case of two endangered Mexican spruces

“…This results give insights of a future biodiversity scenario, where REPS will rely on translocations beyond their native ranges (including across country borders) to subsist in nature, considering the global amount of rare species and their vulnerabilities ( Işik, 2011 ; Enquist et al, 2019 ). Therefore, new mechanisms of international cooperation need to be discussed to deal with this expected crisis triggered by climatic change ( Román-Palacios & Wiens, 2020 ; Brodie et al, 2021 ; McDonald & McCormack, 2021 ).…”

Addressing the Climate Change Adaptation Gap: Key Themes and Future Directions

“…The insufficiency of adaptation finance in adequately addressing the adaptation priorities of developing nations can be attributed primarily to the inherent design of guidance [16,17]. Overcoming this gap requires prioritizing adaptation funding, increasing financial commitments, improving access to funding, and developing innovative financial instruments [18,19].…”

The 2030 Agenda and sustainable development in tourism firms: Board gender diversity and environmental policy on natural resource use

“…Urgent action to protect the planet is needed in a world where human activity is destroying the natural environment and depleting the planet's limited resources. This urgent need has prompted responses from numerous organisations (McDonald & McCormack, 2021). One example is the adoption of the 2030 Agenda, which is built on five pillars (People, Planet, Prosperity, Peace and Partnership) and consists of 17 goals.…”
