RESUMEN

EFSA was asked for a partial risk assessment of Spodoptera frugiperda for the territory of the EU focussing on the main pathways for entry, factors affecting establishment, risk reduction options and pest management. As a polyphagous pest, five commodity pathways were examined in detail. Aggregating across these and other pathways, we estimate that tens of thousands to over a million individual larvae could enter the EU annually on host commodities. Instigating risk reduction options on sweetcorn, a principal host, reduces entry on that pathway 100-fold. However, sweetcorn imports are a small proportion of all S. frugiperda host imports, several of which are already regulated and further regulation is estimated to reduce the median number entering over all pathways by approximately 10%. Low temperatures limit the area for establishment but small areas of Spain, Italy and Greece can provide climatic conditions suitable for establishment. If infested imported commodities are distributed across the EU in proportion to consumer population, a few hundreds to a few thousands of individuals would reach NUTS 2 regions within which suitable conditions for establishment exist. Although S. frugiperda is a known migrant, entry directly into the EU from extant populations in sub-Saharan Africa is judged not feasible. However, if S. frugiperda were to establish in North Africa, in the range of thousands to over two million adults could seasonally migrate into the southern EU. Entry into suitable NUTS2 areas via migration will be greater than via commercial trade but is contingent on the establishment of S. frugiperda in North Africa. The likelihood of entry of the pest via natural dispersal could only be mitigated via control of the pest in Africa. If S. frugiperda were to arrive and become a pest of maize in the EU, Integrated Pest Management (IPM) or broad spectrum insecticides currently used against existing pests could be applied.

RESUMEN

RESUMEN Las legumbres juegan un rol fundamental en la seguridad alimentaria y nutricional (SAN) de millones de personas en todo el mundo. Se estima que alrededor de 50 millones de agricultores familiares las producen, consumen y comercializan (a baja escala) de forma tradicional. La Asamblea General de las Naciones Unidas, en su 68° sesión en 2013, reconoció su importancia al declarar 2016 como el Año Internacional de las Legumbres (AIL2016). La Organización de las Naciones Unidas para la Alimentación y la Agricultura (FAO) fue designada para llevar a cabo las actividades de promoción del Año, en colaboración con gobiernos, organizaciones no gubernamentales, academia y otros actores relevantes interesados. El Año tiene como objetivo aumentar la conciencia pública sobre los beneficios nutricionales y para la salud que tienen las legumbres como parte de los sistemas alimentarios sostenibles dirigidos a mejorar la SAN; revalorizar su aporte de proteínas; promover su producción global; resaltar sus cualidades para mejorar la rotación de cultivos y adaptación al cambio climático; y dar respuesta a los retos para su comercialización.


ABSTRACT Legumes play a key role in food and nutritional security (FNS) for millions of people around the world, with an estimated 50 million family farmers producing, consuming and marketing (low-scale) legumes in a traditional way. At its 68th session in 2013, the General Assembly of the United Nations declared 2016 as the International Year of Legumes. The Food and Agriculture Organization of the United Nations was designated to facilitate the implementation of the legume year in collaboration with governments, non-governmental organizations, academia and other stakeholders. The purpose of the year of the legume was to increase public awareness of the nutritional and health benefits that legumes have, as part of a sustainable food systems, focused on improving FNS; revaluing legume-based proteins; promoting global production; highlighting its quality to encourage better crop rotation and adaptation to climate change; and responding to the markets challenges.

RESUMEN

To assess the impact of training resource-poor maize farmers on the Pacific Plain of Nicaragua in the use of integrated pest management (IPM), 1,200 farmers received training during two years. CARE trained 13 extensionists and they provided intensive training to 60 promoter-farmers, who trained the 1,200 farmers. The farmers were trained in: the dangers of pesticides, recognition of the important organisms (pests and beneficials) in their fields, the biology and ecology of the organisms, how to determine pest population levels, how to choose the best method and product for control, and how to make decisions in the fields according to their new understanding and simple cost-benefit analysis. Three groups of farmers were monitored for two years: the intensively trained farmers (60 promoter-farmers), the trained farmers (1,200), and a group of "control" farmers who did not receive training during the first two years. After two years, the trained farmers used fewer pesticides, spent less money on pest control, made higher net returns, and suffered less exposure to cholinesterase-inhibiting pesticides than did farmers who did not receive IPM training. In addition, a comparison of cholinesterase levels of farmers who used personal protective equipment showed no reduction of exposure to organophosphate insecticides, compared with farmers who did not use the equipment.
