AGM, 111. Report of the Joint Commission on Agricultural Meteorology (CAgM)/Joint Commission on Marine Meteorology and Oceanography (JCOMM) Task Team on Weather, Climate and Fisheries (2014-2018)
This is the summary report of the Joint Task Team of the Commission on Agricultural Meteorology (CAgM)/Joint Commission on Marine Meteorology and Oceanography (JCOMM) on Weather, Climate and Fisheries that was active from 2014-2018. The report focuses on the following themes: Climate variability impacts of selected fisheries: impacts of climate change on fisheries; risk assessment and management evaluation tools for the ecosystem-approach to management of fisheries; weather and climate tools for integrated coastal management of coastal fisheries and marine agriculture; weather and climate too ...
Drought and Water Scarcity (WMO-No. 1284)
World Meteorological Organization (WMO) ; IDMP expert panel with 14 experts from various IDMP partner organizations including UNCCD and FAO - WMO, 2022Driven by climate change, population growth, economic development, and poor water management, the increasingly limited availability of freshwater resources is a fundamental concern for societies worldwide. Drought and water scarcity – two major phenomena that challenge water security – know no national boundaries and affect all socioeconomic sectors of society, with a greater impact on the more vulnerable, poorer or marginalized populations.
Drought is a natural climatic feature of below-average precipitation, which can last for months or years, while water scarcity results from a long- ...
AGM, 110. Commission on Agricultural Meteorology (CAgM) - Expert Team 3.1 ‐ Report on Drought (2014‐2018)
This report is the output from the Commission for Agricultural Meteorology (CAgM) Expert Team on Drought (Expert Team 3.1) from 2014 to 2018. The team members addressed several Terms of Reference (TOR) requested by the 16th Session of the WMO CAgM held in Antalya, Turkey in April 2014. These TORs included the following: (a) Review the definition of drought and conduct a comprehensive review of the definitions and phases of drought (onset, duration, recovery and the ‘end point’ of drought in all regions); (b) Identify case studies and conduct a literature review of the socio‐economic impacts ...
AGM, 109. Assessment of Simple Farmer Rain Gauges Used in the WMO METAGRI OPS Project
The purpose of the various METAGRI projects in West Africa was to increase the flow of information from National Meteorological and Hydrological Services to farmers and this included the need for simple rain gauges to be distributed to farmers. The METAGRI OPERATIONAL Project needed technical specifications for the ‘farmer’s rain gauge’ to make it more suitable for the purpose. The former Commission for Instruments and Methods of Observation (CIMO) Lead Centre agreed to cooperate with the involved NMHSs in the evaluation of the rain gauges by technical consultations, laboratory tests and fiel ...
AGM, 108. Manual For Creating a Weather-based Crop Calendar : A Case Study from Senegal
Crop calendars, indicating the optimal time of planting and the time of harvest, can aid both farmers and advisory experts in the field of agriculture to reduce any risks. Existing crop calendars are made available for many countries but the planting and harvest periods are very general and can even comprise a period of two months. Defining the onset of the rainy season for the different regions and providing more detailed information about crop cultivation in relation to the length of the growing season, will help farmers reduce their losses and increase crop yield. This report describex a me ...

National Water Model, Part 1: Science and Products
This lesson provides an introduction to the benefits, important input (forcing data), and key products of the National Water Model. Both official and evolving products are presented. The lesson uses the flooding associated with Hurricane Harvey in August 2017 to demonstrate key products.
Dam Failure Concepts and Modeling
This lesson provides an in-depth case study to illustrate principles of dam failure modeling and examines some of the critical data inputs and outputs. Output is provided from the U.S. Army Corps of Engineers HEC-RAS model for simulated failures of a large dam. Several simulations are presented that show the impact from varying the size of the breach and the time it takes the breach to fully develop. The lesson also summarizes several infamous large dam failures from around the world and the impacts from other factors are such as reservoir shape and size, the age of the dam, and the material u ...
Using the Local Climate Analysis Tool (LCAT) for Water Resilience Decisions
This lesson offers users of climate information a demonstration of the utility of the Local Climate Analysis Tool (LCAT) for water resources applications. The training follows a NOAA Climate Resilience Toolkit case study in Tampa, Florida, and illustrates how LCAT analyses can be used to inform the steps to climate resilience outlined in the Toolkit. This text-based, interactive lesson will be accessible to anyone using LCAT for water resources decision-making, though will be most useful to those with some familiarity with drought/water resources questions and information needs. Some backgroun ...
Diagnosis of floods/drought and their associated circulation anomaly over Malawi
Floods and droughts are one of extreme weather climatic events that result in loss of life and property in Malawi. However, a well detailed knowledge of understanding of previous extreme climatic events and their associated impacts can be a precautionary in reducing their impacts, as it will help to project future events timely. Therefore this paper presents an analysis of Dec-Feb seasonal flood/drought events and their associated circulation anomalies over Malawi. The DJF seasonal flood/drought was studied using monthly data from 9 selected stations for the period of 1978-2010. A set of regio ...
Integrated Drought Management Programme Working Paper, 01. Benefits of action and costs of inaction: Drought mitigation and preparedness – a literature review
This review of available literature on the benefits of action and costs of inaction of drought mitigation and preparedness shows that significant progress has been made over the past decade in improving understanding of droughts and their impacts. However, significant gaps in research, policy and practice remain. This paper reviews several methodologies for making economic drought impact assessments and describes the main obstacles and opportunities facing the transition from crisis management to risk management. It identifies drivers of ex ante and ex post action against drought and highlight ...
Climate and Water Resources Management, Part 1: Climate Variability and Change
Climate is changing at unprecedented rates in recorded history. A variety of lines of evidence demonstrate that climate change is likely to affect the hydrologic cycle and thus create new challenges in water management. This requires that climate change information be included in water and water-related resources planning, operations, and management. Climate and Water Resources Management, Part 1: Climate Variability and Change describes the terminology, global evidence, regional manifestations, and basic science of global climate variability and anthropogenic change, with a focus on water res ...
