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 ...

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 field intercomparisons. The matters are closely related to the area of expertise of the WMO CIMO Italian Lead Centre, which, according to its Terms of Reference, should be instrumental in CIMO efforts to bridge gaps between countries by assisting CIMO in conducting training and capacity building. The work performed at the Lead Centre consisted in a preliminary laboratory assessment of instrument accuracy, held in 2015 at the rain gauge laboratory of the University of Genoa (I), for a set of gauges provided by the METAGRI OPS. Following the laboratory tests, an intercomparison campaign was held using the same gauges at the field test site of the Lead Centre in Vigna di Valle (Rome, I). This final report aims to describe the activities performed during the cooperation and to synthesise the results achieved. It also provides guidance material for improving the measurement accuracy and fostering standardization.

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.

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 methodology for building a crop calendar of high quality, to better inform local farmers and advisory services in this field. The first part of this manual describes the methodology in three sections, so that this can be replicated for other countries with a distinct rainy season. The second part consists of a case study for Senegal, where this methodology has been tested and crop calendars were created as an output. Rainfall data for this country was provided by ANACIM, who were also involved in this project. This work could not have been completed without the support provided by Agence Nationale de l'Aviation Civile et de la Météorologie/ National Agency of Civil Aviation and Meteorology (ANACIM). Through a collaboration where rainfall data, knowledge and information were exchanged, a qualitative analysis of the methodology could be executed for Senegal. In addition, this work was funded by the Food and Agricultural Organization of the United Nations (FAO) under a joint WMO and FAO project. WMO would like to graciously acknowledge the continued collaboration and support of FAO on issues related to agricultural meteorology.
