Evaluating Loss and Damage Due to Climate Change

The research reveals four loss and damage pathways. Residual impacts of climate stressors occur when:

1. existing coping/adaptation to biophysical impact is not enough;
2. measures have costs (including non-economic) that cannot be regained;
3. despite short-term merits, measures have negative effects in the longer term; or
4. no measures are adopted - or possible - at all.
   
   Steps to Help Curb Global Climate Change

   
   Scientists offer new evidence that a potent chemical mechanism operating in the roots of a tropical grass used for livestock feed has enormous potential to reduce greenhouse gas emissions.

The articles in this special issue provide evidence that loss and damage happens simultaneously with efforts by people to adjust to climatic stressors. The evidence illustrates loss and damage around barriers and limits to adaptation: growing food and livelihood insecurity, unreliable water supplies, deteriorating human welfare and increasing manifestation of erosive coping measures (e.g. eating less, distress sale of productive assets to buy food, reducing the years of schooling for children, etc.). These negative impacts touch upon people's welfare and health, social cohesion, culture and identity - values that contribute to the functioning of society but which elude monetary valuation.

The publication of this set of research papers is very timely as loss and damage will be a key topic during the climate negotiations in Warsaw next month (11-22 November 2013), and empirical evidence is still scarce. The findings also contribute to the emerging body of literature on adaptation limits and constraints, a topic that - for the first time - is discussed in a separate chapter of the Fifth Assessment Report of the Intergovernmental Panel on Climate Change, Working Group 2 (IPCC AR5 WG2).

The issues that have arisen through this research point to an even greater urgency for ambitious mitigation and adaptation that are sufficient to manage climate stressors. If this goal is missed, loss and damage will undermine society's ability to pursue sustainable development.

"The special issue of the International Journal of Global Warming focuses on a crucial topic: 'Loss and damage' which refers to adverse effects of climate variability and climate change that occur despite mitigation and adaptation efforts," Editor-in-Chief Ibrahim Dincer of the University of Ontario Institute of Technology says. The issue reports on the first ever multi-country study on this emerging topic from the perspective of vulnerable communities in Africa, Asia and the Pacific. The research papers included show that current mitigation and adaptation efforts are not enough. People across the study sites were not passive victims of climate change. A large majority implemented a wide variety of adaptation and coping measures to avoid impacts of climate stressors, but these measures were often insufficient or came at a cost. The negative effects were not simply monetary, there were cultural losses and non-economic costs, in terms of time investment, social-cohesion and livelihood security, were also widespread. "IJGW positions itself uniquely by addressing the issue and offering solutions," Dincer adds.
