FOOD SECURITY A Vital Sustainable Development Issue
Food Security
Food Security
CURRENT SITUATION • Around 805mn people in the world suffer from chronic undernourishment.
• That’s about one in nine people of the 7.3bn global population. • 13.5% of the population of developing countries doesn’t get enough to eat on a daily basis. • There are 11mn undernourished people in the developed world. • The global number is likely to increase as the population grows to 9bn by 2050
Food Security
FEEDING THE HUNGRY • Feeding the global population of 9.1bn in 2050 would require raising food production by around 70% between 2007 and 2050. • With 69% of the global population expected to be urban by 2050, the land under agriculture is shrinking at a faster rate. • Accurate agricultural information is a prerequisite in understanding sustainable agricultural development and food security.
Food Security
GEOSPATIAL TECH TO THE RESCUE • Feeding the global population of 9.1bn in 2050 would require raising food production by around 70% between 2007 and 2050. • Geospatial technology helps survey the global status of crop production at all times and delivers that message across a diverse set of stakeholders • Accurate geoinformation helps realize required food production • The launch of Landsat in 1972 ushered in the modern era of global land observations and monitoring. • Since then remote sensing has been an integral part of agriculture and food security programs of governments and agencies around the world.
Food Security
CURRENT PRACTICES • Geoinformation technologies play a crucial role in development of digital terrain database. • The availability of remote sensing-based topographic datasets has opened new venues for hydrologic and geomorphologic studies. • Location technologies play a critical role in the generation of spatial data layers and their integration to estimate soil loss by adopting suitable models. • There are few innovative and well-demonstrated remote sensing-based operational projects in dryland areas. • Satellite data is analyzed with ground-based information on agro-meteorology, and market economics to estimate crop acreage and production much before the harvest.
Food Security
INITIATIVES: NASA • NASA’s Socioeconomic Data and Applications Center offers a variety of interdisciplinary data. • The agriculture and food security theme spans global data holdings and resources that touch on the proportion of cropland and pasture. • The SEDAC portal provides access to several global agriculture-related data sets. • This includes global agricultural lands that show the proportion of land area used as cropland and pasture.
INITIATIVES: ESRI
Food Security
• Geoinformation technologies play a crucial role in development of digital terrain database. • In cooperation with USGS and Amazon Web Services, Esri is providing easy access to temporal multispectral Landsat 8 imagery. • The Web services enable any organization to quickly access the latest Landsat 8 imagery for visualization and analysis. • It provides valuable trend analysis of agriculture applications. • For any location, various temporal indices and band combinations can be directly accessed. • The services provide on-the-fly processing based on ArcGIS Image Services running on AWS cloud infrastructure • It is accessible through ArcGIS Online. • Each day, new Landsat 8 scenes are added to the service to support the previous scenes from 2015 and a large collection from previous years.
Food Security
INTRODUCING FEWS NET • Famine Early Warning Systems Network, is a leading provider of early warning and analysis on acute food insecurity. • Created by the US Agency for International Development, FEWS NET provides objective, evidence-based analysis to help government decision-makers. • FEWS NET analysts, spread in more than 35 countries, continuously gather evidence of the current food security situation in areas of concern. • Data is collected from a variety of sources, including US science agencies, national ministries of trade and agriculture, and NGOs. • The network has 20 ‘presence’ countries, where locally-based analysts work full-time from a national office.
Food Security
THE ROAD AHEAD
• FAO will need to fund projects to make geospatial information more affordable and readily available for the end user. • As open-access policies for sharing geospatial information and technology become an integral part of solving the food security equation. • Geospatial technologies, such as, remote sensing, GNSS and GIS will keep expanding to provide powerful tools in almost every aspect of food security. • Feeding a population of 9 billion by 2050 will not be easy, but robust monitoring programs with timely, reliable information will certainly be an important asset.
