Hydro-climate and meteorological data support the food security agenda

Hydro-climate and meteorological data support the food security agenda

An integration of the agrometeorological, climatological and hydrological expertise of WMO with socioeconomic and geophysical data and water resources management practices is required to support food security.

WMO supports resolving the equation of water demand for human consumption, irrigation requirements, water availability and potential water storage and provides advice to optimize rainfed and irrigated agriculture. The water-energy-food nexus should be considered as well.

Agriculture and food security

Agricultural Meteorology Programme Salas District, Ica Peru


The agricultural sector critically depends on timely and accurate weather, climate and water information, particularly as it faces increasing climate risks. Timely weather and climate forecasts as well as water-related information enable the agricultural community to increase crop and livestock yields, plan planting and harvest time, and reduce pests and diseases. 


Public Weather Services

Climate Services for the Food Security Sector


The core business of National Meteorological and Hydrological Services is to serve public good by providing reliable and timely weather, climate and related information to the community at large. National Meteorological and Hydrological Services also strive to support local governments when it comes to the use of scarce resources, such as water and energy, and to provide targeted services for agriculture.


Energy systems are the engine of economic and social development. Energy is essential to practically all aspects of human welfare – access to water, agricultural productivity, health care, education, job creation, environmental sustainability and more. Energy investments represent a sizeable portion of Gross Domestic Product but, at the same time, energy sector emissions account for the largest share of anthropogenic greenhouse gas emissions.
