ABSTRACT.
Most countries lack effective policies to manage climate risks, despite growing concerns with climate change. We analyzed the policy evolution from a disaster management to a risk management approach, using as a case study four agricultural droughts that impacted Uruguay?s livestock sector in the last three decades. A transdisciplinary team of researchers, extension workers, and policy makers agreed on a common conceptual framework for the interpretation of past droughts and policies. The evidence presented shows that the set of actions implemented at different levels when facing droughts were mainly reactive in the past but later evolved to a more integral risk management approach. A greater interinstitutional integration and a decreasing gap between science and policy were identified during the period of study. Social and political learning enabled a vision of proactive management and promoted effective adaptive measures. While the Government of Uruguay explicitly incorporated the issue of adaptation to climate change to its agenda, research institutions also fostered the creation of interdisciplinary study groups on this topic, resulting in new stages of learning. The recent changes in public policies, institutional governance and academic research, have contributed to enhance the adaptive capacity of the agricultural sector to climate variability, and in particular to drought. This study confirms the relevance and need to work within a transdisciplinary framework to effectively address the different social learning dimensions, particularly those concerning the adaptation to global change.

ABSTRACT.
The objective of this research was to determinate and modeling the runoff for different soils classes based on different simulated rainfall intensities (30, 60 and 120mm h-1) in different soils in Uruguay. A portable rainfall simulator with multiple nozzles was used to simulate different rainfall intensities. On each soil was measured the initial time and rate of runoff, rainfall (total, duration and intensities), direction of slope, crop residue and cover percentage, soil densities (bulk and particle), soil porosity (bulk, macro and micro), textural fractions (clay, silt and sand), initial and saturated soil moisture. The runoff was estimated with Smith's modified model. The accumulate runoff losses were 64, 32, 30 e 15% from the total rainfall, for Vertissolo 1, Chernossolo, Argissolo e Vertissolo 2, respectively. The relationship between initial runoff and the runoff rate was inversively, independently of the soil surface and rainfall conditions. Increasing rainfall intensity decreases the initial runoff time and increase runoff rate. Smith's modified model provides a better runoff estimated in soils with high soil moisture content.
RESUMO.
Os objetivos deste trabalho foram determinar e modelar o escoamento superficial para solos com diferentes características físicas a partir de diferentes intensidades de chuva. Foram realizadas chuvas simuladas em diferentes solos, no Uruguai. Chuvas artificiais com intensidades de 30, 60 e 120mm h-1 foram aplicadas utilizando-se um simulador estacionário de bicos múltiplos e oscilantes. Em cada solo foram determinados o tempo de início e a taxa de escoamento superficial, além da chuva (quantidade, duração e intensidade), declividade do terreno, matéria seca na superfície e cobertura do solo, densidade (do solo e de partícula), porosidade do solo (macro, micro e total), textura (argila, silte e areia), umidade inicial e saturação do solo. Foi utilizado o modelo modificado de Smith para estimativa do escoamento superficial. As perdas acumuladas por escoamento superficial foram de 64, 32, 30 e 15% do total aplicado para Vertissolo 1, Chernossolo, Argissolo e Vertissolo 2, respectivamente. Há uma relação inversa entre o tempo de início do escoamento e a taxa constante de escoamento superficial, independentemente das condições da superfície do solo e da chuva. Isso está associado à intensidade da chuva, pois quanto mais esta aumentar, menor é o tempo de início do escoamento e maior é a taxa constante de escoamento superficial. O modelo modificado de Smith estima melhor o escoamento superficial sob condições de elevada umidade do solo. MenosABSTRACT.
