  • Persistent Drought Challenges Fracking

     Feature Article CleantechIQ.com - Executive Commentary Freshwater has historically been the base fluid essential for fracking, sweeping, and oil sands recovery because it has been abundant and readily available, and because of its low cost. Unfortunately, all of that is now changing due to a longer than expected global drought, and the industry is examining new options and ...

  • Early warning of disasters: Facts and figures

    Lucy Pearson looks at early warning systems for disasters, their uses and limits, and what accounts for the gap between warning and action. Through history disasters have destroyed lives and livelihoods, killing people and damaging homes and businesses. Disasters in the past 35 years have taken an estimated 2.5 million lives and cost more than US$1.5 billion, mainly in developing ...

  • The Missing Link: Droughts, the Economy and Climate Change

    The effects of the vast drought afflicting America’s farm belt are rippling across the economy. Major companies apparently feeling the heat from rising crop prices include McDonald’s, Smithfield Foods and Arthur Daniels Midland, which processes agricultural commodities. More than half of ...

  • Using disaster warning tools to their best potential

    Stronger links between scientific tools and the environment in which they operate can improve the effectiveness of early warning. To say there is a lot riding on disaster management is an understatement. The lives and livelihoods lost, as well as extensive damage, underscore the human, ...

  • Why disaster warning and development go hand in hand

    To engage people in early action we must understand their experience, behaviour and constraints, says disaster policy expert Andrew Collins. Disaster predictions have significant uncertainty that tends to undermine efforts to act on early warnings. In Bangladesh, for example, where there ...

  • Differences in Spatial Patterns of Drought on Different Time Scales: An Analysis of the Iberian Peninsula

    The differences in spatial patterns of drought over a range of time scales were analysed by the Standardized Precipitation Index (SPI). In a climatic area with a wide range of precipitation characteristics (the Iberian Peninsula), Pearson III distribution is flexible enough to calculate the drought index on different time scales. The Pearson III distribution was adapted to precipitation ...

  • Acting on disaster warnings: Don`t miss the human factor

    We need to understand why some people act on early warnings while others ignore them, says disaster preparedness specialist Sudhir Kumar. The Great East Japan Earthquake and subsequent tsunami of 11 March 2011 challenged global ideas about responding to disasters. It showed that structural defences alone, such as breakwaters, coastal dykes and tidal barriers, cannot provide protection ...

  • Strengthening drought risk management and policy: UNESCO International Hydrological Programme's case studies from Africa and Latin America and the Caribbean

    Droughts have resulted in significant socio-economic impacts in the regions of Africa and Latin America and the Caribbean (LAC), especially in developing countries. The main gaps to mitigate its effects, identified in both Africa and LAC regions, include a lack of human and institutional capacity, a lack of access to relevant early warning information for decision-making, the identification of ...

  • Improving drought risk modelling: using multiple periods of satellite data with ensembles of data mining algorithms

    This paper describes improvements to the Vegetation Outlook (VegOut) model developed by the National Drought Mitigation Center for the USA. VegOut provides early drought warning by predicting general vegetation conditions at multiple time steps (e.g., 2–, 4– and 6–week outlooks). VegOut integrates climate, biophysical, oceanic, and satellite–based vegetation data with data mining algorithms to ...

  • Drought policy in Mexico: a long, slow march toward an integrated and preventive management model

    Mexico is exposed to droughts and vulnerable to their impacts. Despite a history of serious economic and social consequences from drought, until recently national water policy did not acknowledge this type of natural disaster as a priority issue. This paper analyses how drought policy in Mexico has evolved since the creation of the National Water Commission in 1989 up to 2013, when the most ...

  • Drought class transition analysis through different models: a case study in North China

    The standardized precipitation index (SPI) and standardized runoff index (SRI) are computed for several gauge stations in Panjiakou Reservoir catchment of Luanhe Basin, a drought prone region of North China. Based on the SPI and SRI time series, two different models, a weighted Markov chain model and a Volterra adaptive filter model for chaotic time series, were established to predict drought ...

  • Emergency logistics and risk mitigation in Thailand following the Asian tsunami

    A series of recent natural disasters (earthquakes, floods, droughts) and man-made crises (civil unrest, war, political disturbance) have highlighted the vulnerability of communities to unstable conditions. Reaching displaced people in crisis conditions is heavily dependent on the effectiveness of the supply chain and its management systems. Disaster responses have been modelled into, for example, ...

  • The connection between climate change and recent extreme weather events

    What do we know about the connection between climate change and recent extreme weather events, such as the heat waves, drought, and fires? Scientists agree that climate change has already primed the pump for extreme weather events: A recent report by National Oceanic and Atmospheric Administration (NOAA) scientists compared the rising risk of extreme weather events to a baseball ...

  • The importance of groundwater monitoring

    Groundwater monitoring is an essential element in any environmental information system. Based upon validated groundwater monitoring data, information is derived on which decisions can be made. Constant monitoring provides the necessary data input for your smart environment and is basically the basis of the decision making process concerning spatial planning and climate change adaptation. As in ...

  • Learning lessons from wildfires, from Texas to Brazil

    “This is unprecedented fire behavior. We’ve never seen conditions like this before. Not a single one of our firefighters has ever faced such extreme conditions.” This statement from the director of the Texas Forest Service makes it clear that the recent wildfires that scorched Texas belong in a new category of disaster. Already, the state’s wildfires this season ...

  • Nigeria `must close climate change communication gap`

    Nigeria must close a "communication gap" to ensure that vital information on climate change-related events reaches all those who could use it to help minimise their impact, the head of the country's meteorological body has warned. Speaking at the yearly meeting of the African Science Academies, held ...

  • Perspectives from the field: Ecosystem-based approaches to disaster risk reduction

    UNEP - Starting this week at the Third World Conference on Disaster Risk Reduction, the international community is expected to approve the next ten year plan to strengthen the resilience of countries and communities against disasters. The task at hand is a critically important one, particularly as the number of people affected by disasters has already doubled over the past decade and is expected ...
