The Weather: What’s the Outlook?
New sources of atmospheric observations, faster supercomputers and advances in science together revolutionized weather forecasting in the latter part of the 20th century. On the global scale, we can today predict up to five days ahead as accurately as we could do for three days 20 years ago. This means society has much more advance warning of weather hazards than before, permitting people to prepare and, thereby, limit the loss of lives and property. Expectations are high for even greater advances in the years to come.

Forecasting Heavy Rains and Landslides in Eastern Africa
Good rainfall draws many people to settle across the eastern Africa highlands for farming and other businesses. However, factors such as steep terrain, logging, livestock grazing, agriculture, and construction, have increased erosion and contributed to less stable slopes. These factors can lead to devastating landslides and mudslides, especially during episodes of very heavy rain. Forecasting and monitoring heavy rainfall is challenging, especially in mountainous regions that have few surface observations. This make satellite data critical for meteorologists and hydrologists forecasting for th ...

Flood Management Tool Series, Technical Document, 23. Health and Sanitation Aspects of Flood Management
Flood events are known for their profound capacity to positively or negatively affect humans. Floods improve overall human well-being by providing services such as groundwater recharge, surface-water replenishment, soil-fertility enhancement and a general increase in the value of social–ecological systems. Equally, however, flood events pose a series of diverse health threats, ranging from contaminated water sources to decreased agricultural productivity, especially when communities are vulnerable and lack the capacity to effectively respond to, and recover from, the adverse effects of floods. ...
Flood Management Tool Series, Technical Document, 22. The role of the media in flood management
Communication is the imparting or exchange of information between individuals or groups through a common system of symbols, signs or behaviour (Merriam-Webster, 2013a; Oxford Dictionaries, 2013). In recent decades, different conceptual models have been developed to explain the process of human communication. One of the best representations of the flow of information in flood communication is the Interactional Communication Model proposed by Schramm (Schramm, 1954).
Flood Management Tool Series, Technical Document, 21. Effectiveness of flood management measures
It is not enough to assert—to an elected official, a regulator, a donor organization or the taxpayer—that one’s organization is doing an effective job of flood management. One also has to be able to provide a credible answer to the question: “How do you know?” 2 There is a multiplicity of flood management activities that can be pursued by a plethora of government jurisdictions, government agencies, NGOs, private and volunteer groups— independently, in cooperation, in competition. These activities may include: constructing flood prevention infrastructure; rebuilding houses, buildings and infras ...
