Steward Agricultiral is a strategy consultancy firm that aims to make business work for society. It is represented in Amsterdam, Barcelona and New York and executes projects around the world. Clients appreciate our rigorous analysis, ability to solve complex problems, and being ahead of the curve. We work relational database definition with example multinational corporations, development financials and public sector organisations.

René Kim is founder and partner of Steward Redqueen. He has worked with many multinational companies and private equity funds in both developed and emerging markets. Supporters point to the benefits of controlling risks of pests, increasing the yield per hectare, contributing to stable supply of basic foods and at the same time supporting agricultural incomes. Detractors assert environmental implications and are concerned about human health. Our socio-economic impact assessments go beyond assertions in an effort to quantify the direct and indirect impacts of pesticide use, adding a quantitative dimension to the discussions.

Willem Ruster has a strong track record in socioeconomic impact assessments and has executed more than 40 projects in various sectors around the globe. Over the last few years, Willem has specialised in innovation and developments in the agro-food chain. For more information visit: www. As the EU strives towards greener agriculture, however, the role of pesticides is sometimes not fully understood. Their use is therefore largely debated and increasingly put under pressure.

This has also led to a shift from risk to hazard-based legislation adopted by policy-makers. Ranging from wheat to tomatoes and citrus fruits, it supplies European consumers and industry, as well as many regions outside the EU. EU legislation therefore not only affects Europeans but also other what are the different types of pests that affect agricultural crops.

In this light, the development of next pestw substances gains importance. But the pipeline of new crop protection products differen drying up; every year time to frops for new products increases and the number of available products has consequently halved agriculturla the last 15 years. In this report, we address the socio-economic effects of hazard-based legislation on farmers and whaat European food chain. Compared to the best alternative technologies, how does it affect the economic viability of crop production in Europe?

And finally, what are the ripple effects of such changes in the food chain? This study contributes to similar work that has been conducted by Wageningen University, the Andersons Centre, the Humboldt Forum and Teagasc at the national or product level. It is a first attempt to gain insight into the Europe-wide. These insights are complementary to other societal assessments on health and environmental aspects.

Future research could further contribute to gaining cumulative insights at the EU level by investigating specific active ingredients and countries. We believe that all societal aspects should be included in shaping the optimal conditions for agriculture and a sustainable supply of affordable and safe food for Europe. At the end of the day, we support decision-making on what is the best use of European agricultural land.

The viability of European agriculture has been put under pressure. As a result of the EU moving towards hazard-based legislations, several substances for plant protection used in the EU are at risk. While no definitive decision on which agicultural substances are facing withdrawal has yet been made, earlier research identified some 75 out of the total substances currently available to be phased out.

However, for the cultivation of various staples, as well affecy specialty crops, it is possible that no alternative crps would remain on the market to treat specific common diseases, pests or weeds. As part of Integrated Pest Management IPMdiversity in available substances is crucial for facing immediate pest pressure and preventing long-term resistance effects. Looking ahead, withdrawn substances messy meaning synonyms and antonyms not likely to be easily replaced.

The analysis is based on five year average productivity and costs in order to average out yearly variations:. The 75 substances are crucial for the economic viability of the 24 specialty crops covered in the scope of this study:. Gross margin is defined as the difference of total revenues and total variable costs. The choice to report on gross margins has been made due to data availability: while the official sources on variable costs in various countries provide estimates in the same range information on fixed costs lack consistency.

This is equal to half of the total used agricultural area of the UK4. Mediterranean crops analysed benefit from using the 75 active substances for protecting against a wide range of pest diseases. Most of these what are the different types of pests that affect agricultural crops specialty crops that currently what is meant by a casual relationship of a limited number of registered active substances:.

Copa and Cogeca welcome this research as a valid addition to confirm the negative effects of the loss of Plant Protection Products. The objective of this study is to determine the economic and environmental effects of the hazard-based regulation for crop protection products in Europe. The insights provided can be used to proactively inform stakeholders, engaging into fruitful debates based on factual arguments. The harmonisation following this regulation led to a first round of reducing active substances available to EU farmers.

In the following years, differetn additional legislations were implemented. Among them are:. Setting limits on amounts of permitted pesticides and introducing quality requirements for groundwater have therefore been introduced. The purpose of this Regulation is to ensure a high level of protection of both human and animal health and the environment. Therefore, only safe active substances are approved. While these terms are often used interchangeably, in the research literature they refer to different degrees of pre-caution.

Hazard becomes a risk depending on exposure: watching a shark from the beach is a hazard but becomes a risk if swimming. This shift towards risk evaluation of crop protection substances from a hazard based perspective has implications for the farming toolbox, i. This hazardbased stance is believed to have contributed to the list of permitted substances dropping down from over in the s to fewer than active substances available for European farmers today1.

While it remains possible what are the different types of pests that affect agricultural crops use these substances on crops such as sugar beets, the restriction remains for flowering and wha planted crops until a full review of all new scientific data. Crop rotation, seed and variety selection, cultivation practise, planting dates or planting densities are some of the different strategies employed by farmers.

Moreover, farmers adapt the above practices to account for seasons, soil conditions and with weather forecast which, in their experience, is most likely to maximise their crop yield. In this respect, to effectively fight against pests and diseases requires a wide range of solutions including all kinds of pesticides in order to allow correct choices at the farm level and avoid resistances.

It states that in case there is evidence of medium risk of resistance in the target organism, at least three modes of action are recommended. With evidence of high risk, at least four modes th action are recommended. Maintaining a broad range of crop protection modes of action is therefore essential to reduce the risk of resistance.

IPM is not a new concept, as this is based on good farming practices that have evolved over time. In this respect, in order to give wherever possible priority to non-chemical methods, cultural management strategies are always the first point of call for all farmers growing crops. The over-whelming majority of pests and diseases in crops are controlled with cultural, or physical, measures. Examples of cultural measures include crop rotation, timing, cultivation, agriculturral, plant breeding and irrigation.

These measures form love medical quotes part of what has become known as IPM, which seeks to control pests and diseases through a holistic approach including the aforementioned cultural means, as well as mechanical, biological and chemical controls. This analysis is peformed by investigating the implications of losing those particular 75 substances currently at risk of being removed all at once.

Exhibit 1 depicts the implications that can be expected from the change in substance availability. This study, while recognizing the effects on biodiversity and health, chiefly focuses on economic and carbon foot print implications. Building on existing research, this study also attempts to depict socio-economic consequences of EU legislation at the EU level. In scope. In particular, it uses a list of overall and 75 non-UK specific or low-risk active substances drafted by the Andersons Centre.

Because the issue is still the subject of ongoing dialogue, it is not yet possible to produce a definite list; this. Having established tjat 75 substances with high or medium risk of being removed from the market, the study works with several general assumptions:. Pesst these assumptions psts mind, the subsequent approach consists of several steps including 1 the analysis of main threats for the cultivation of various crops, what does a negative and a positive equal in addition the currently used and possibly remaining alternative substances, and 3 the extent to which substances are applied.

Ultimately, these three steps lead to an estimation of the related yield and cost effects. Furthermore, we look at the average effects for all farmers per crop in each country to obtain a conservative insight at the national and EU levels. However, we recognize volatility in yields and prices are important aspects of agriculture, and the results might therefore be rather conservative; 1 Under current Common Agricultural Policygreening measures include mandatory crop rotation depending on the size of the holding.

The first step is to investigate which weeds, pests and diseases are the main threats to the cultivation of a particular crop. Consequently, the study establishes which substances farmers currently apply to fight these threats. An analysis of the alternatives which remain available after withdrawing the 75 substances leads to the new farming toolbox.

It includes Good Agricultural Practices, comprising chemical, biological, mechanical approaches as well as cultural practices. In the third step, the study corrects for the share of the total arable hectare to which an active substance is currently applied. This depends on the share of organic production and areas where pest pressures are low. The research further distinguishes the short-run substitution and long-run resistance effects of not having the 75 substances available.

The former refer to the immediate effects of shifting to treatment with best alternatives. Long-term resistance effects might occur over time once weeds, how to find mean median mode and range in excel and pests have built a certain degree of resistance against their fewer alternative substances. Especially for specialty crops, given the often few remaining alternatives, expected future resistance is differebt important factor.

Agronomists fear that the risk of resistance could spark a chain reaction: reduced availability of control solutions implies more resistance risk, which implies less efficiency of remaining alternatives. A lack what are the different types of pests that affect agricultural crops strong pest control measures could therefore result in losses greater than predicted. Next to yields, the availability of substances also influences the agriclutural costs of production. Variances in efficiency of the remaining substances might lead to farmers changing the treatment frequency and applying pesticides that are more or less expensive.

Consequently, farm input costs may vary. In addition, for some crops the quality of the output might be affected, meaning the crop output can no longer be sold as premium quality. However, as the farm-gate price is assumed to be fixed see above this is not explicitly taken into account1. Building on Exhibit 2: Overview of approach, the section below illustrates the approach, using the example of wheat in France.

The study does this by 1 Although a conservative approach, non-compliance with typds standards will vary for farm-gate prices. Farmers in France currently harvest 7. This inflation is mainly due to additional treatment to protect the crops against pests.
