Brochure, flyer, fact-sheetGuidelineAlianza Mundial Por el Suelo - Directrices básicas para preparar una muestra de suelo para el control de calidad interno 2021
Also available in:
El control de calidad (QC) es un conjunto de actividades o técnicas destinadas a garantizar el cumplimiento de todos los requisitos de calidad. El seguimiento continuo de las operaciones y los resultados del laboratorio es esencial para decidir si los resultados son lo suficientemente fiables como para ser publicados. Los laboratorios que emprenden un conjunto de procedimientos para supervisar sus operaciones y resultados trabajan en su control de calidad interno. Estas directrices fueron preparadas por la Red Mundial de Laboratorios de Suelos (GLOSOLAN) para apoyar y animar a los laboratorios de suelos a realizar controles de calidad internos. De este modo, aumentar su precisión en el análisis de suelos. -
BookletCorporate general interestProcedimiento operativo estándar para el análisis de carbono orgánico del suelo Walkley-Black Métodos de titulación y colorimétrico 2021Este protocolo aplica a la determinación del contenido de Carbono Orgánico Oxidable en suelo. El contenido de carbono orgánico es calculado a partir de la cantidad de ion cromo (Cr3+) formado, utilizando un método de titulación o colorimétrico, la presencia de cloruro (>0.5% Cl-) producirá una interferencia positiva en suelos salinos. El desvío resultante de la presencia de cloruro puede ser corregido (Rayment y Lyons, 2011). Este método es descripto en Nelson y Sommers (1996) y el método descripto aquí no aplica a la corrección por cloruros.

Book (stand-alone)Technical report2022 Global Report on Food Crises
Joint analysis for better decisions
2022Also available in:
No results found.The 2022 Global Report on Food Crises (GRFC 2022) highlights the alarming deterioration of acute food insecurity in 2021 in numerous food-crisis countries/territories. Nearly 193 million people were in Crisis or worse (IPC/CH Phase 3 or above) or equivalent in 53 countries/territories where comparable data were available in 2021 – as a result of intensified conflict, significant economic shocks and some of the most severe weather extremes in recent years, or a combination of these drivers -
Book (series)FlagshipThe State of Food Security and Nutrition in the World 2021
Transforming food systems for food security, improved nutrition and affordable healthy diets for all
2021In recent years, several major drivers have put the world off track to ending world hunger and malnutrition in all its forms by 2030. The challenges have grown with the COVID-19 pandemic and related containment measures. This report presents the first global assessment of food insecurity and malnutrition for 2020 and offers some indication of what hunger might look like by 2030 in a scenario further complicated by the enduring effects of the COVID-19 pandemic. It also includes new estimates of the cost and affordability of healthy diets, which provide an important link between the food security and nutrition indicators and the analysis of their trends. Altogether, the report highlights the need for a deeper reflection on how to better address the global food security and nutrition situation.To understand how hunger and malnutrition have reached these critical levels, this report draws on the analyses of the past four editions, which have produced a vast, evidence-based body of knowledge of the major drivers behind the recent changes in food security and nutrition. These drivers, which are increasing in frequency and intensity, include conflicts, climate variability and extremes, and economic slowdowns and downturns – all exacerbated by the underlying causes of poverty and very high and persistent levels of inequality. In addition, millions of people around the world suffer from food insecurity and different forms of malnutrition because they cannot afford the cost of healthy diets. From a synthesized understanding of this knowledge, updates and additional analyses are generated to create a holistic view of the combined effects of these drivers, both on each other and on food systems, and how they negatively affect food security and nutrition around the world.In turn, the evidence informs an in-depth look at how to move from silo solutions to integrated food systems solutions. In this regard, the report proposes transformative pathways that specifically address the challenges posed by the major drivers, also highlighting the types of policy and investment portfolios required to transform food systems for food security, improved nutrition, and affordable healthy diets for all. The report observes that, while the pandemic has caused major setbacks, there is much to be learned from the vulnerabilities and inequalities it has laid bare. If taken to heart, these new insights and wisdom can help get the world back on track towards the goal of ending hunger, food insecurity, and malnutrition in all its forms. -
