Synopsis (short abstract) The Sudan's agricultural sector contributes a third of the country’s gross domestic product (GDP) and supports two-thirds of the population, but faces significant challenges due to heavy floods and other extreme weather events. However, the Sudan lacks an effective system for monitoring flooded farmlands, hindering disaster preparedness and response. This issue arises due to several factors such as limited access to data on flood-affected areas, difficulties in adopting advanced technologies like remote sensing and GIS, and the country's vast size, remote regions and unpredictable flooding patterns. Without a reliable monitoring system, early warnings and preventive measures cannot be implemented, leaving farmers exposed to recurring losses and exacerbating food insecurity. This assessment utilizes remote sensing data to analyse flood impacts on Sudanese agriculture between 2012 and 2024, aiming to establish a national baseline and enhance early warning systems. As flooding and other extreme weather events increase in severity, it is imperative that mitigation strategies are developed to support farmers in flood-prone regions such as the Sudan. Findings show significant annual variations, with peak flood extents in August and September. Sennar and Gedaref were the most affected states for rainfed croplands, while Aj Jazirah had the highest flood extent in irrigated croplands. The flood risk map highlights southeastern states as the most vulnerable, underscoring the need for improved flood monitoring and early warning systems.

Afghanistan: Assessment on flood damage
DIEM-Impact report, May 2024
2024

Also available in:

No results found.

Since March 2024, Afghanistan has experienced heavy rains. Major flood damage has been reported in several provinces, with extensive and severe impacts. The first flood events that occurred in March and April 2024 affected areas in the north, centre and parts of Nimroz. The May events were dispersed over a larger area, but affected a high proportion of districts in Badakhshan and Nimroz. The Food and Agriculture Organization of the United Nations (FAO) Data in Emergencies (DIEM) conducted geographic information system exposure analysis and collected data from primary and secondary sources. Data were collected in three rounds from 24 April to 30 May 2024 across 104 districts and 654 communities in 20 provinces. The secondary sources included FAO Regional Offices and implementing partner records of affected communities at district level. FAO established DIEM-Impact to provide a granular and rapid understanding of the impact of large-scale hazards on agriculture and agricultural livelihoods using a variety of assessment methodologies, including primary and secondary information, remote sensing technologies, and FAO’s damage and loss methodology. DIEM-Impact presents a regularly updated and accessible state of food insecurity in fragile environments, and helps underpin FAO's programming based on evidence.

Feasibility of anticipatory action in the Pacific Islands region 2024

Also available in:

No results found.

This report seeks to expand the understanding of anticipatory action in Small Island Developing States, with a focus on the geographic and socio-institutional aspects of independent Pacific Island Countries in the Southwest Pacific Ocean. This report provides a summary of regional and selected national contexts and approaches to the building blocks of anticipatory action in the Pacific Island Countries region.Through a combination of workshops and interviews with government agencies, regional organizations, international NGOs, multilateral groups, and country-based participants, the report provides a synthesized context for anticipatory action in the region. A case study section presents the anticipatory action context for Palau, Solomon Islands and Fiji. The discussion and conclusions point towards the feasibility of advancing anticipatory action and the broad governance that will need to be facilitated to formalize anticipatory actions.

A rapid geospatial flood impact assessment in Pakistan, 2022 2022

Also available in:

No results found.

Pakistan is among the ten countries most affected by extreme weather events despite its very low carbon footprint, according to the Global Climate Risk Index 2021 and Climate Watch. Frequent natural disasters negatively impact the agricultural sector and household livelihoods, and push thousands of people into poverty and hunger. In 2022, intense rainfall in monsoon season caused severe flooding across Pakistan and impacted a large number of people and households including deaths of people, damage to infrastructure (including roads, dams, buildings, electricity poles etc.), destruction of agricultural area and pushed millions of people into poverty and hunger. Since the beginning of the rainy season, it is reported that over 735 000 livestock have perished, and about 2 million acres of crops have been adversely impacted (UNCT, 2022).
