Abstract. Extreme events are part of climate variability. Dealing with variability is still a challenge that might be increased due to climate change. However, impacts of extreme events are not only dependent on their variability, but also on management and governance. In Brazil, its semi-arid region is vulnerable to extreme events, especially droughts, for centuries. Actually, other Brazilian regions that have been mostly concerned with floods are currently also experiencing droughts. This article evaluates how a combination between climate variability and water governance might affect water scarcity and increase the impacts of extreme events on some regions. For this evaluation, Ostrom's framework for analyzing social-ecological systems (SES) was applied. Ostrom's framework is useful for understanding interactions between resource systems, governance systems and resource users. This study focuses on social-ecological systems located in a drought-prone region of Brazil. Two extreme events were selected, one in 1997–2000, when Brazil's new water policy was very young, and the other one in 2012–2015. The analysis of SES considering Ostrom's principle "Clearly defined boundaries" showed that deficiencies in water management cause the intensification of drought's impacts for the water users. The reasons are more related to water management and governance problems than to drought event magnitude or climate change. This is a problem that holdup advances in dealing with extreme events.

Scale Integration

Design and management of the Indus Basin Irrigation System are aimed at achieving equity in canal water supply. This concept, which is more than a century old, ignores the due aspect of groundwater management in today's perspective. Recent research has proved that variation in irrigation demand and rainfall within the irrigation units has given birth to varying stresses on groundwater. In response to spatial climate variability, reallocation of canal supplies from the head towards the tail of the Lower Bari Doab Canal (LBDC) command was evaluated in this study, with the objective of achieving equitable total irrigation costs. The ensuing groundwater regime was simulated for 50 years' time with a groundwater model. A 25% reallocation from head towards tail-end improves the standard deviation of total irrigation cost equity from 1905 to 241. This command scale integration of available water resources also demonstrated a net saving in groundwater pumping cost to the tune of 7.24 to 18.9%, in comparison with existing equitable canal supplies. With this approach, at least minimal or no waterlogging in the head-end area, even during wet years, and no groundwater mining in the tail-end, even during dry periods, are anticipated. In addition, this system-scale integrated water management would increase adaptive capacity to climate change adaptation.

There is evidence of the increasing economic losses from extreme natural events during the last decades. These facts, thought to be triggered by environmental changes coupled with inefficient management and policies, highlight particularly exposed and vulnerable regions worldwide. Argentina faces several challenges associated with global environmental change and climate variability, especially related to water resources management including extreme floods and droughts. At the same time, the country's production capacity (i.e. natural resource-based commodities) and future development opportunities are closely tied to the sustainable development of its natural resource endowments. Given that vulnerability is registered not only by exposure to hazards (perturbations and stresses), but also resides in the sensitivity and resilience of the system experiencing such hazards, Argentina will need to improve its water management capacities to reduce its vulnerability to climate variability and change. This paper presents the basic components of the vulnerability analysis and suggests how it can be used to define efficient water management options.
