Sustainable irrigation expansion over water limited croplands is an important measure to enhance agricultural yields and increase the resilience of crop production to global warming. While existing global assessments of irrigation expansion mainly illustrate the biophysical potential for irrigation, socioeconomic factors such as weak governance or low income, that demonstrably impede the successful implementation of sustainable irrigation, remain largely underexplored.
Here we provide five scenarios of sustainable irrigation deployment in the 21st century integrated into the framework of Shared Socioeconomic Pathways, which account for biophysical irrigation limits and socioeconomic constraints. We find that the potential for sustainable irrigation expansion implied by biophysical limits alone is considerably reduced when socioeconomic factors are considered.
Defining a Regional Goal on Adaptation for the Caribbean
While the Global Goal on Adaptation provides a collective goal for adapting to climate change, adaptation is often a context specific and localised process. This paper proposes a Regional Goal on Adaptation for the Caribbean based on priorities relevant for Caribbean small island developing states.
Adaptation constraints in scenarios of socio-economic development
Here, we combine data on documented adaptation from the Global Adaptation Mapping Initiative with national macro indicators and assess future changes in adaptation constraints alongside the Shared Socioeconomic Pathways, spanning a wide range of future socio-economic development scenarios.
Towards scenario representation of adaptive capacity for global climate change assessments
Climate change adaptation needs, as well as the capacity to adapt, are unequally distributed around the world. Here we propose ways to quantify adaptive capacity within the framework of Shared Socioeconomic Pathways, a scenario set widely used by climate impact and integrated assessment models.
Risks of synchronised low yields are underestimated in climate and crop model projections
This study finds that the jet stream – air currents in the upper atmosphere – can synchronise extreme weather caused by climate change, resulting in crop failures in multiple countries at the same time.
De la CDN 1.0 à la CDN 2.0: qu'est-ce qui a changé dans les CDN des PMA de l’Afrique de l'Ouest?
La présente étude examine les premières et les secondes Contributions Déterminées au niveau National des onze pays les moins avancés de l’Afrique de l’Ouest à savoir le Bénin, le Burkina Faso, la Gambie, la Guinée, la Guinée Bissau, le Libéria, le Mali, le Niger, le Sénégal, la Sierra Leone et le Togo.
Representation of adaptation in quantitative climate assessments
Adaptation is a key societal response to reduce the impacts of climate change, yet it is poorly represented in current modelling frameworks. We identify key research gaps and suggest entry points for adaptation in quantitative assessments of climate change to enhance policy guidance.
Uncompensated claims to fair emission space risk putting Paris Agreement goals out of reach
Interacting adaptation constraints in the Caribbean highlight the importance of sustained adaptation finance
Climate justice and loss and damage: Hurricane Dorian, Haitians and human rights
Haitian communities were the locus of the majority of deaths and missing people attributed to the 2019 Hurricane Dorian and faced a series of distributional, procedural and recognition injustices. We investigate the historical factors and contemporary conditions of Haitian communities in The Bahamas that resulted in significant inequities, disproportional impacts and infractions of human rights.
Long term strategies: low carbon growth, resilience and prosperity for Least Developed Countries
Long-term, low greenhouse gas emission development strategies provide a beneficial space for Least Developed Countries to set out a visionary blueprint for a resilient, decarbonised future, compatible with limiting warming to 1.5°C.
Fossil gas: a bridge to nowhere
This report assesses how fast fossil gas power generation must be phased out in different parts of the world to keep the Paris Agreement’s 1.5°C temperature goal in reach.
