    Progress on farmer training in parasitic weed management / L'état d’avancement de la formation des agriculteurs dans la gestionde mauvaises herbes parasites 2008

    The damage caused by the parasites Orobanche on field and vegetable crops in Northern Africa and the Near East, and Striga on cereals in several countries of Africa South of the Sahara is significant. For instance, in Morocco, infestation of Orobanche crenata in food legumes (mainly faba bean) causes yield losses of 29 000 tonnes annually, which is equal to US$17 million. The complete devastation caused by Orobanche in many areas of North Africa and the Near East has to be reduced; oth erwise farmers will abandon their fields or shift to other crops. The situation of the effect of Striga on crops such as sorghum, maize and millet is similar. No single method has so far been found to successfully control the root parasitic weeds Orobanche and Striga. For this reason, an integrated control approach is required that should be feasible for small-scale farmers to implement. Understanding the problem of these parasitic plants, the damage they cause to crops and to f armers economies, FAO decided to implement two regional projects, where the main component was farmer training. The idea was to familiarize farmers with the biology of the weeds and allow them to propose or adapt control strategies.

    FAO establishes and publishes specifications* for technical material and related formulations of agricultural pesticides, with the objective that these specifications may be used to provide an international point of reference against which products can be judged either for regulatory purposes or in commercial dealings. From 1999 onward, the development of FAO specifications follows the New Procedure, described first in the 5th edition of the "Manual on the development and use of FAO specifications for plant protection products" and later in the 1st edition of “Manual for Development and Use of FAO and WHO Specifications for Pesticides” (2002) - currently available as 3rd revision of the 1st edition (2016), which is available only on the internet through the FAO and WHO web sites. This document is the information on HALOXYFOP-P-METHYL _ methyl(R)-2-[4-(3-chloro-5-trifluoromethyl-2-pyridyloxy)phenoxy]propionate

    The State of Food Security and Nutrition in the World 2021
    Transforming food systems for food security, improved nutrition and affordable healthy diets for all
    2021
    In 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.

    What will be needed to realize the vision of a world free from hunger and malnutrition? After shedding light on the nature of the challenges that agriculture and food systems are facing now and throughout the 21st century, the study provides insights into what is at stake and what needs to be done. “Business as usual” is not an option. Major transformations in agricultural systems, rural economies, and natural resources management are necessary. The present study was undertaken for the quadrennial review of FAO’s strategic framework and for the preparation of the Organization Medium-Term plan 2018-2021.
