3 Pesqueclima Vulnerability of Fishery Communities to Climate Variability, in the Estuary of dos Patos Lagoon I Ibero-American Workshop on Climate Dynamics, Climate Change, and Regional Climate Modeling São Paulo, SP, Brazil, August, 2007.

4 I Ibero-American Workshop on Climate Dynamics, Climate Change, and Regional Climate Modeling 4 Pesqueclima Evaluate the impact of climate variability in social and economical vulnerability of communities that fish shrimp in the estuarine region of dos Patos Lagoon; Provide climate forecasting design- ed to the needs of those com- munities, and contingency plans to climate situations that are not ade- quate to perform their economical activities.

Uncertainties Higher vulnerability, due to uncertainties on the success of catches. Adaptation Low adaptation and learning in all systems, except 4.

Vulnerability and resilience of those artisan fishery com- munities depend strongly on their degree of organization. Strengthen of organization; Program to forecast shrimp catches; Plan of alternate options in case of negative results; Improvement on fish commerce; Better distribution of financial resources; Register again all fishers.

33 I Ibero-American Workshop on Climate Dynamics, Climate Change, and Regional Climate Modeling 33 Extreme Events of Precipitation in Rio Grande Observed precitation in Rio Grande is not always that of the drainage area in NCDC. Spatial and temporal patterns are simulated well by RegCM3 in most events; Mensal forecast errors often exceed ±5-30%. Errors decrease in seasonal (3months) average, especially in SU2 region;

34 I Ibero-American Workshop on Climate Dynamics, Climate Change, and Regional Climate Modeling 34 Extreme Events of Precipitation in Rio Grande Error in region SU1 for seasonal average is high, due to boundary distance. Gas parameterization produces errors smaller or equal to Gfc ones. The analysis should be extend to establish a better representation of cumulus convention in the southern region of Brazil.
