No results found.Durant la 3ème décade de novembre, les estimations de FEWS-NET (figure 1) indiquaient que des conditions arides perduraient dans l'Aire grégarigène et s'étendaient à l'Aire d’invasion (compartiment Centre). La pluviosité variait de 4 à 10 mm dans le secteur sud de l’Aire grégarigène et dans quelques localités du secteur Centre de l’Aire de multiplication initiale. Dans les autres secteurs, elle était comprise entre 0 et 4 mm. Dans l’Aire d’invasion, sur une bande diagonale de 200 km de large, de Besalampy (AIC-O) à Manajary (AIE-C), la pluviosité était au maximum de 4 mm. Dans les autres secteurs de l’Aire d’invasion, la pluviosité variait de 4 à 40 mm sauf dans quelques localités des secteurs Nord Betsiboka Hautes-Terres et Est Ankay où elle dépassait 40 mm. -

No results found.Durant la 3ème décade de novembre 2013, les informations issues du site de FEWS-NET indiquent que, dans l’Aire d’invasion, les pluies enregistrées montraient une variation peu significative par rapport à celles de la 2ème décade, alors que dans l’Aire grégarigène, les pluies furent plus importantes que celles de la 2ème décade. Par rapport au besoin du Criquet migrateur malgache, la pluviosité était excédentaire dans l’Aire de multiplication initiale : 79,2 mm à Analamary, 96,0 mm à Isoanala, 68 ,0 mm à Ianabinda, 78,5 mm à Zazafotsy et 44,0 mm à Tsivory. La pluviosité enregistrée était moyenne dans l’Aire transitoire de multiplication et déficitaire dans les Aires de densation Nord et Centre. (voir annexe 9) Dans l’Aire d’invasion, le taux de verdissement était de l’ordre de 90 à 95 % et les strates herbeuses avaient une hauteur de l’ordre de 20 à 30 cm. Dans l’Aire grégarigène, les pâturages avaient un taux de verdissement de l’ordre de 80 à 90 % et une hauteur variant de 15 à 25 cm. L’humidité du sol était présente jusqu’à 30 cm de profondeur dans l’Aire d’invasion et 25 cm de profondeur dans l’Aire grégarigène. Concernant les vents dominants, ils continuaient à souffler de l’Ouest vers l’Est. -

Book (series)Technical studyThe impact of climate variability and extremes on agriculture and food security - An analysis of the evidence and case studies
Background paper for The State of Food Security and Nutrition in the World 2018
2020Also available in:
No results found.Global climate studies show that not only temperatures are increasing and precipitation levels are becoming more varied, all projections indicate these trends will continue. It is therefore imperative that we understand changes in climate over agricultural areas and their impacts on agriculture production and food security. This study presents new analysis on the impact of changing climate on agriculture and food security, by examining the evidence on recent climate variability and extremes over agricultural areas and the impact of these on agriculture and food security. It shows that more countries are exposed to increasing climate variability and extremes and the frequency (the number of years exposed in a five-year period) and intensity (the number of types of climate extremes in a five-year period) of exposure over agricultural areas have increased. The findings of this study are compelling and bring urgency to the fact that climate variability and extremes are proliferating and intensifying and are contributing to a rise in global hunger. The world’s 2.5 billion small-scale farmers, herders, fishers, and forest-dependent people, who derive their food and income from renewable natural resources, are most at risk and affected. Actions to strengthen the resilience of livelihoods and food systems to climate variability and extremes urgently need to be scaled up and accelerated. -
Book (series)FlagshipThe State of Food Security and Nutrition in the World 2023
Urbanization, agrifood systems transformation and healthy diets across the rural–urban continuum
2023This report provides an update on global progress towards the targets of ending hunger (SDG Target 2.1) and all forms of malnutrition (SDG Target 2.2) and estimates on the number of people who are unable to afford a healthy diet. Since its 2017 edition, this report has repeatedly highlighted that the intensification and interaction of conflict, climate extremes and economic slowdowns and downturns, combined with highly unaffordable nutritious foods and growing inequality, are pushing us off track to meet the SDG 2 targets. However, other important megatrends must also be factored into the analysis to fully understand the challenges and opportunities for meeting the SDG 2 targets. One such megatrend, and the focus of this year’s report, is urbanization. New evidence shows that food purchases in some countries are no longer high only among urban households but also among rural households. Consumption of highly processed foods is also increasing in peri-urban and rural areas of some countries. These changes are affecting people’s food security and nutrition in ways that differ depending on where they live across the rural–urban continuum. This timely and relevant theme is aligned with the United Nations General Assembly-endorsed New Urban Agenda, and the report provides recommendations on the policies, investments and actions needed to address the challenges of agrifood systems transformation under urbanization and to enable opportunities for ensuring access to affordable healthy diets for everyone. -
Book (series)Technical studyLatin America and the Caribbean - Regional Overview of Food Security and Nutrition 2023
Statistics and trends
2023Also available in:
The 2023 edition of the Regional Overview of Food Security and Nutrition in Latin America and the Caribbean presents an update of the data and trends in food security and nutrition in recent years. The impact of the COVID-19 pandemic, the climate crisis and the conflict in Ukraine, as well as the economic slowdown, rising food inflation and income inequality have had an impact on regional figures. The most recent data shows that, between 2021 and 2022, progress was made in reducing hunger and food insecurity in Latin America and the Caribbean. However, the progress achieved is far from the targets established to meet SDG 2 of ending hunger. In addition, one in five people in the region cannot access a healthy diet and malnutrition in all its forms, including child stunting, micronutrient deficiencies and obesity continue to be a major challenge.
