Sampling system for LUCAS 2015

The sampling design of LUCAS 2015 took into account experience from previous campaigns. While remaining a Two-phase sampling scheme, efforts were focused in reducing the set of excluded points from the second phase sample, which are placed in difficult and inaccessible areas. This action was implemented both through: 1. the improvement of the first phase sample (LUCAS master sample) by updating each point of the grid with the most recent available information (NUTS borders, road network, elevation, Corine Land Cover results (CLC2006)) 2. the fine-tuning of the past rule for eligibility of the point introducing an additional new indicator of accessibility based on CLC; the final criteria combine all the auxiliary information [Elevation, Road distance, Slope, CLC indicator]. However excluded points will remain a likely source of bias which has to be treated separately from the field survey. The corresponding excluded area needs to be covered with a complementary photo-interpretation operation, including an ex-post photo-interpretation also for 2012 and 2009 surveys. Such a photo-interpretation task, although important and linked to the sampling exercise, is not addressed in this document but represents next priority for the future work.JRC.H.4-Monitoring Agricultural Resource

Using GIS and Remote Sensing to build Master Sampling Frames for Agricultural Statistics

This report is a JRC contribution to the FAO Global Strategy to improve Agricultural and Rural Statistics (GSARS). Its aim is providing guidelines on the suitable ways to use satellite images and geographic information tools to build master sampling frames that can be used both for agricultural and environmental statistics. The main readers to which the report is addressed are agricultural and environmental statisticians in developing countries. We consider separately the use of technological tools for area sampling frames and for list sampling frames. The use of Global Navigation Satellite Systems (GNSS), better known as GPS, is also discussed, although its use is more connected to carrying out field surveys rather than to the design of sampling frames.JRC.H.4-Monitoring Agricultural Resource

Agricultural Insurance Schemes II

Index insurances, diversely from traditional agricultural insurances, do not refer to the actual farm losses but to the losses evaluated from an index. The study evaluates the feasibility of index insurances for EU and makes a cross-validation based on the yield loss risk calculated from FADN data. Premiums have been estimated for a Regional Yield Insurance (RYI) for FADN regions and a number of arable crops. Some meteorological, agro-meteorological and NDVI indicators were also analysed according to the model of the area yield-tailored insurance. From the statistical analysis the indicators do not explain yields optimally. Due to the strong heterogeneity within the EU regions, a meteorological yield-tailored index could have a better explanation capacity at a more disaggregated level. FADN data are used to compute and map the risk of yield reduction for major field crops and of income reduction by farm type. The cross validation of area yield insurance consisted on the calculation of the risk with FADN data with and without insurance. Results show that the risk reduction capacity of yield area index for the case analysed is not very high, but in some regions the risk can be reduced up to a 68%. The risk reduction capacity of other indexes is expected to be lower than the yield area index. Finally, the study shows that index products efficiency is relatively low at farm level due to the European heterogeneity of climates and geography and to the large geographical scale that had to be used in the study. So, index products could be more efficient for reinsurance that works at aggregated level.JRC.G.3-Monitoring agricultural resource

Agricultural Insurance Schemes

Agricultural producers face a series of risks affecting the income and welfare of their households. These are mainly production risks related to weather conditions, pests and diseases, market conditions, liberalization policies, climate change, etc. In recent years the European Union has been considering a possible integration of risk management in the common agricultural policy and is analysing risk and crisis management strategies to provide an improved response to crises in the agricultural sector. This report reviews the agricultural risk management systems in the EU-27 (candidate countries Turkey and Croatia are also analysed) with a special focus on types of agricultural insurance. The study contains a collection of data on the realities and modalities of agricultural insurance in Europe. This information mainly comes from fact sheets filled in by experts or consultants from the different European countries and data from the European Committee of Insurers (CEA). Many of these data were unpublished because there is no obligation for the insurance companies to report to the EU institutions. The report quantifies and maps different types of risks, from climatic risks to yield and revenue risks. The role of Governments in helping farmers to face disasters is analyzed for every country: providing aid ex-post and offering or subsidizing insurances. The Member States definitions of crisis and disaster when authorising state aids are described and contrasted with the EU and international legislation. Aid is sometimes given on an ad-hoc basis through compensation schemes, or funds partially financed by the agricultural sector (on a voluntary or compulsory basis). Mutual funds, calamity funds and ad-hoc payments existing in European countries are summarised. The levels of ad-hoc payments per country are compared. Agricultural insurances are fostered in a number of countries. The different types of agricultural insurance systems and key figures in each country are analysed. Some technicalities are described, such as reinsurance, triggers and deductibles. The relationship between Government involvement and insurance development is highlighted. Usually private companies insure only hail and fire, and the government subsidies and public reinsurance are needed to make possible the insurance of agricultural systemic risks. One conclusion is that the risk management tools available in the Member States (MS) could be further developed. Conditions for a feasible EU-wide insurance scheme have been analysed. The possible amount of costs of an EU-supported insurance system has been roughly quantified for a few hypothetical scenarios. However, given the heterogeneous situation in the MS, the interest of a harmonised EU-wide system of agricultural insurances is debatable.JRC.G.3-Agricultur

Long-term monitoring of tropical moist forest extent (from 1990 to 2019): Description of the dataset

The need for accurate information on the state and evolution of tropical forest types at regional and continental scales is widely recognized, particularly to analyze the forest diversity and dynamics, to assess degradation and deforestation processes and to better manage these natural resources. Here we document the approach that was developed by JRC to map and monitor the extent of moist tropical forests and their changes (degradation, deforestation and regrowth) over the last three decades (1990-2020) at fine spatial resolution (30 m × 30 m). The approach is based on the analysis of each valid observation from the Landsat archive and allows to capture disturbances with a short-duration appearance on satellite imagery such as selective logging, fires, and severe weather events (hurricanes, dryness). This new approach allows characterizing the sequential dynamics of forest cover changes by providing transition stages from the initial observation period to the most recent year (2019 for this report). For the first time at the pantropical scale the occurrence and extent of forest degradation can be documented on an annual basis in addition to the monitoring of deforestation. After a short introduction (chapter 1), this technical report describes the study area (chapter 2), the input data (chapter 3), the method that has been developed (chapter 4), and the outcomes of this study (chapter 5). A discussion is also provided regarding the specificities and added value of the outcomes (chapter 6), and the known limitations and future expected improvements (chapter 7). This new pan-tropical scale deforestation and forest degradation monitoring system will contribute to the EU Observatory on deforestation, forest degradation, changes in the world’s forest cover, and associated drivers, which is an action being implemented in the framework of the Communication from the Commission to step up EU action to protect and restore the World’s forests (COM(2019) 352).JRC.D.1-Bio-econom

Hyperkalemia in Heart Failure Patients in Spain and Its Impact on Guidelines and Recommendations: ESC-EORP-HFA Heart Failure Long-Term Registry

[Abstract] Introduction and objectives: Hyperkalemia is a growing concern in the treatment of patients with heart failure and reduced ejection fraction because it limits the use of effective drugs. We report estimates of the magnitude of this problem in routine clinical practice in Spain, as well as changes in potassium levels during follow-up and associated factors. Methods: This study included patients with acute (n=881) or chronic (n=3587) heart failure recruited in 28 Spanish hospitals of the European heart failure registry of the European Society of Cardiology and followed up for 1 year. Various outcomes were analyzed, including changes in serum potassium levels and their impact on treatment. Results: Hyperkalemia (K+> 5.4 mEq/L) was identified in 4.3% (95%CI, 3.7%-5.0%) and 8.2% (6.5%-10.2%) of patients with chronic and acute heart failure, respectively, and was responsible for 28.9% of all cases of contraindication to mineralocorticoid receptor antagonist use and for 10.8% of all cases of failure to reach the target dose. Serum potassium levels were not recorded in 291 (10.8%) of the 2693 chronic heart failure patients with reduced ejection fraction. During follow-up, potassium levels increased in 179 of 1431 patients (12.5%, 95%CI, 10.8%-14.3%). This increase was directly related to age, diabetes, and history of stroke and was inversely related to history of hyperkalemia. Conclusions: This study highlights the magnitude of the problem of hyperkalemia in patients with heart failure in everyday clinical practice and the need to improve monitoring of this factor in these patients due to its interference with the possibility of receiving optimal treatment.[Resumen] Introducción y objetivos. La hiperpotasemia es una preocupación creciente en el tratamiento de los pacientes con insuficiencia cardiaca y fracción de eyección reducida, pues limita el uso de fármacos eficaces. Este trabajo ofrece estimaciones de la magnitud de este problema en la práctica clínica habitual en España, los cambios en las concentraciones de potasio en el seguimiento y los factores asociados. Métodos. Pacientes con insuficiencia cardiaca aguda (n = 881) y crónica (n = 3.587) seleccionados en 28 hospitales españoles del registro europeo de insuficiencia cardiaca de la European Society of Cardiology y seguidos 1 año para diferentes desenlaces, incluidos cambios en las cifras de potasio y su impacto en el tratamiento. Resultados. La hiperpotasemia (K+ > 5,4 mEq/l) está presente en el 4,3% (IC95%, 3,7-5,0%) y el 8,2% (6,5-10,2%) de los pacientes con insuficiencia cardiaca crónica y aguda; causa el 28,9% de todos los casos en que se contraindica el uso de antagonistas del receptor de mineralocorticoides y el 10,8% de los que no alcanzan la dosis objetivo. Del total de 2.693 pacientes ambulatorios con fracción de eyección reducida, 291 (10,8%) no tenían registrada medición de potasio. Durante el seguimiento, 179 de 1.431 (12,5%, IC95%, 10,8-14,3%) aumentaron su concentración de potasio, aumento relacionado directamente con la edad, la diabetes mellitus y los antecedentes de ictus e inversamente con los antecedentes de hiperpotasemia. Conclusiones. Este trabajo destaca el problema de la hiperpotasemia en pacientes con insuficiencia cardiaca de la práctica clínica habitual y la necesidad de continuar y mejorar la vigilancia de este factor en estos pacientes por su interferencia en el tratamiento óptimo
