  • Source for data is the World BankTRENDS IN TEMPERATURE AND RAINFALL IN COLOMBIA:In recent years, rainy seasons have been occurring earlier for central Columbia than 25 years ago. For the period of 1961-1990, annual precipitation has varied significantly, between -4 and +6 percent. For the period of 1995–2005 a relative precipitation increase of 5 percent from December to February is noted.Positive tendency for intense rainfall events and consecutive dry days.Between 1990 and 2000, an 82 percent reduction in glaciers has been observed, showing a linear withdrawal of the ice of 10-15 m, yearly. Under current climate trends, glaciers located in Colombia will disappear completely within the next 100 years.Increasing trends of daily mean and minimum temperature are noted for the past 30–40 years. Temperature has increased on the order of 1°C in the last 20 years.TRENDS IN TEMPERATURE AND RAINFALL IN MALAWI:As year-to-year variability in rainfall is very high in Malawi, long-term trends are difficult to identify. In 2006, wet-season (December-February) rainfall over Malawi was markedly low, possibly causing a decreasing trend in December-February rainfall; however, evidence does not reveal consistent decreases.Mean annual temperature has increased by 0.9°C between 1960 and 2006, an average rate of 0.21°C per decade.The average number of ‘hot’ days per year in Malawi has increased by 30.5 between 1960 and 2003.The average number of ‘hot’ nights per year increased by 41 nights (an additional 11.1% of nights) between 1960 and 2003.The frequency of cold days and nights has decreased significantly since 1960 in all seasons except September-November

    11. 11.  A rapid spatial assessment tool for ecosystem services and their values; not a single model but an artificial intelligence assisted system that customizes models to user goals. Demonstrates a mapping process for ecosystem service provision, use, sink and flow while most ES assessments only look at provision. Probabilistic, Bayesian models inform decision-makers about the likelihood of possible scenarios; users can explore effects of policy changes and external events on estimates of uncertainty.

    15. 15.  The project is working in collaboration with key governmental institutions, such as the Ministry of Forestry and the Ministry for Local Government and Rural Development in Malawi. The project has set up National Steering Committees in Colombia and Malawi with high-profile scientific researchers. Local partners have access to relevant policy-making instances and public- agenda setters: • Malawi TV documentary discussed the potential contribution of the ASSETS project to current environmental issues affecting Malawi. • Caqueta’s Regional Government Development Plan (2012-2015) states that the project’s “scientific contributions are expected to serve as input for the formulation of better policies for intervention, prioritization of actions and management of regional and local authorities”.
