21st century Policymaking for Food Safety & Security: New Challenges and New Dynamics

How to keep pace with rapidly-evolving S&T? (stem cells, nanotechnologies, molecular biology, synthetic genomics)

High degree of complexity, scientific uncertainty

From Lab to Market: stimulating safe, effective innovation

Good evidence base for policy decisions

Introduction

Utilizing S&T for Food Safety & Security

“End hunger, achieve food security and improved nutrition and promote sustainable agriculture targets”

‘Food security exists when all people, at all times, have physical and economic access to sufficient, safe and nutritious food to meet their dietary needs and food preferences for an active and healthy life’ (FAO)

Introduction

6

What Role for Governments?

‘Assuring food safety and quality’

Stimulating innovation: The regulation/innovation interface

Building blocks:

1. R&D policy for emerging technologies

2. Environmental, health and safety risk regulation

Getting the balance right: innovation, trust, and regulation

Introduction

7

Food safety & Security: Why Policy is Important?

Promises and threats:

Securing the promise of science and technology

Sustainable, responsible technology development

Ensuring food safety

Tackling threats to food production

Policy: a law, regulation, procedure or administrative action to

advance a desired outcome

WHAT DOES IT MEAN IN PRACTICE?

Introduction

Today’s lecture

Ensuring food safety & security in three regulatory

contexts

Nanomaterials and Consumer Safety

Sustainable, Responsible R&D

Ecology & Biodiversity

Introduction

9

How governments organize their long term policies and regulation for food safety & security?

2 cases:

1. EU and US: Nanomaterials and food safety

2. EU: Bio-invasions and food security

Introduction

1. EU/US: Nanotech & Food Safety

11

Nanotechnology and nanomaterials

Richard P. Feynman 1918-1988

There's Plenty of Room at the Bottom

December 29th 1959

American Physical Society

Kim Eric Drexler 1955-

From scientific vision to industrial technology

12

Nanotechnology and Nanomaterials: complexity and scope

A basic definition:

Material with one or more external dimensions, or an internal structure, at nanoscale

And which could exhibit novel characteristics compared to the same material at a larger scale (SCENIEIR, EU Scientific

committee)

The size range of nanoparticle – 1-100nm

1 meter = billion nanometer

or

1 nanometer = 1/1,000,000,000 or 1x10^-9 m

The most important elements for technology implementation

Better understanding of physical and chemical reactions at the nanometric scale

An effective process for creating a new and/or improved characteristics

Databases to implement the technology (risks? adverse effects? proven benefits?)

13

Nanotechnology in the food industry

using nanotechnology to improve food production, packaging, and quality

Major commercial applications: [suspensions, crystals, powders] Nanomaterials in food packaging Nanomaterials changing food characteristics Nanotechnology in agriculture

Nano-encapsulation for

nutrient delivery

Nano-sensors and

dispensers - food crops

pesticides encapsulated in

nanoparticles 14

Nanotechnology is not small Government Nanotechnology R&D Expenditures

“Nanotechnology R&D continues to grow in priority on national science agendas in OECD

countries, both in terms of public and private funding.” (OECD, Observer)

15

Nanomaterials:

Challenging scientific basic assumptions

What do we know about risks?

Evidence of toxicity caused by the release of atoms and molecules (Nano-Silver)

Clinical trials: exposure of workers in the industry involves high risk

The incidence of lung, similar to asbestos (Carbon nanotubes(

Unlike ‘normal’ chemical pollution: release of toxic molecules and atoms

Septic blood vessel cells, inflammation and cell death (nano-zinc oxide)

Laboratory experiments: health injury of rats, fish gills and nervous system of mice (titanium dioxide).

[Gilbert, 2009; Wijnhoven et al. 2009 ; Song, Y., X. Li, and X. Du. 2009]

Early-stage eco-toxicity and toxicology research 16

Sounds familiar?

Much scarier than nanotechnology

17

Nanomaterials raise concerns about food regulation

Nanotechnology Environmental and Safety Aspects

Potential Environmental Effects (EU SCENIHR 2009; DG Health and Consumers Protection) Means through which products containing nanomaterials may end up in releases to the

environment (wastewater treatment streams, landfill and combustion of products)

Fate and effects in aquatic environment: The behavior of nanoparticles is expected to depend not only on the physical and chemical character of the nanomaterial, but also and perhaps predominantly on the characteristics of the receiving environment (Chen et al. 2008; Chen and Elimelech 2008)

Upon entry into the environment, nanoparticles may undergo one or more of the following: aggregation in soil and sediments; presence in air; aggregation in aquatic systems etc.

Experimental studies: uptake by biota via respiratory or digestive tracts in animals, or via plant’s root system;

verification methods on ‘what makes nanomaterials active after release’ are limited in scope (e.g. aquatic ecotoxicological fate)

Potential for transfer across food chain levels, depends on material type and food chain (as is the case for bulk materials) (Fortner et al. 2005; Holbrook et al. 2008)

18

Nanotechnology Environmental and Safety Risks: Particular Interest Occupational Exposure to Carbon Nanotubes (CNT) and Nanofibers (CNF) (NIOSH 2010) concerns arises mainly from results of laboratory animal studies

laboratory studies shows a consistent toxicological response (pulmonary inflammation, fibrosis) independent of the study design (i.e., intratracheal, aspiration, and inhalation)

workplace exposure measurements indicate the potential for worker exposure

Food Containing Carbon Nanoparticles, Food Packaging materials (FDA 2012)

Products already on the market that contain CNPs; Many are not labeled as containing nano particles

CNT’s for specific applications and existing products are largely untested for their human health effects.

19

Bio-and-Nanotechnologies R&D policy challenges on food production

■ what?

The problem of scientific uncertainty:

Are current risk assessment criteria relevant?

How to define materials and manufacturing processes?

How to obtain market-data (manufacturing, trading-volumes)?

How to obtain data on toxicological effects?

■ how?

Government activity

R&D policy, design regulation, supervision, enforcement

Degree of supervision:

Expansion? tightening industry regulation?

20

“The regulation of nanotechnology risks and uncertainties is lagging behind technological innovation”

(Greenpeace, environmental defense fund )

The regulatory challenge: addressing issues of scientific and regulatory uncertainty [Accepted definitions; Material Characterization; Risk assessment; Material Safety Date Sheets]

Dilemma no. 1

Global Powers: To Intervene or Not to Intervene???

21

A widespread Understanding: Governance Without Governments Two faces of power:

Regulatory Capacity (related to financial sources; knowledge)

lack of a genuine regulatory capacity that would enable state authorities to govern nanotechnology risks through their own regulatory means independently of the market

Regulatory sovereignty (related to rulemaking, standard-setting)

Reliance on private-rulemaking and voluntary regulation; consequently, private actors retain substantial regulatory autonomy, while state power decreases

Examples: Bowman & Hodge 2008, 2009; Abbott et al.2010; Bowman & Van-Calster 2010; Marchant et al. 2012; Falkner & Jaspers 2012.

22

The paper’s question Does government regulation expand in international nano -policies? The paper’s argument Significant Expansion of Government Rulemaking The argument presented via a series of claims Global private actors still have considerable regulatory power, but the EU and the

US strive to determine the shape and the level of nanochemicals risk regulation.

Regulatory activity in the EU and US takes a new turn not only towards empowerment of their regulatory systems, but also constrains private actors' power to regulate (a highly political issue of power allocation).

Initial comparison: the EU's governance modes are 'more robust' than those of the US federal government.

23

The global Nanochemicals Market

Defining Features:

Total Market-size: unknown

Risks: contested;

limited

observations

Empirical Case

Nanochemical I.D.

▪ a material of nano-size (in the range of 1–100 nm)

▪ displays different physical and chemical characteristics compares to regular chemical

▪ spans many industrial sectors (e.g. food, lubricants, health care, electronics and pharmaceuticals)

▪ particular concern: Nano-Metals (titanium, silver), Nano-Carbones and Nano-Zinc Oxides (commercial uses: textile, UV protection, antibacterial functions (OECD 2008)

▪ Partial estimations of production volumes:

2010: 21,500 tons 2016:~50,000 tons

Among the fastest growing products of the global nanotechnology industry

24

The EU and US in Nanochemicals Risk Regulation Case studies: US: Data-reporting regulation (EPA under TSCA*)

EU: Market-entry regulation (EC under REACH**)

Rationales:

Hotly contested global policy fields

Significant change in the role of the EU and US rulemaking

The limits of privatization; the most likely path towards government rulemaking

Major themes: 1) state sovereignty; 2) power-constrained non-state actors

*Toxic Substances Control Act, 1976

** Registration, Evaluation, Authorisation and Restriction of Chemical substances, 2007

Empirical Case

25

the State of Play in Data-Reporting Regulation: Developments by the EPA under TSCA regulatory system

2. Revoking delegation of rulemaking (ISO, BSI, ATSM and other standards organizations alike)

3. objectives: improving regulatory capacity and market integration 27

Conclusions

Common denominators in governments behavior:

acting decisively to gain more power over the global market

empowerment of regulatory systems

constraining industry power to shape regulation

Findings are not consistent with the common understanding

Findings suggest for the strengthening of governments' regulation

Law at the end of the day!

28

Dilemma no. 2

How To Intervene???

29

The Challenge: Addressing Scientific and Regulatory Uncertainties

Scientific Uncertainty: Material Characterization; Material Safety, Risk assessment; Risk prediction, Environmental Fate, Mammalian Toxicology

Regulatory Uncertainty: The ‘appropriateness’ of existing regulatory frameworks

30

What explains current dynamics? 1. Domestic Environmental Politics: Green Political Parties

European Commission, 2004 'Safe, Integrated, and Responsible' approach

European Commission, 2005-2006 Review of existing legislation

European Commission, 2007, 2008 ‘existing legislation is adequate’

passive, laisser-faire attitude

European Parliament, 2009 'those rules are about as effective in addressing nanotechnology as trying to catch

plankton with a cod fishing net' (Swedish green MEP, Schlyter)

2010 – labelling requirements (food and cosmetics products)

2011 – scientific ‘nanomaterials’ definition – OUT; Accepted political definition - IN

2012-2016 – ongoing review & adjustments (Chemicals, Electric equipment, food, cosmetics, biocidal products regulations); nano-specific risk assessments

31

Justo-Hanani & Dayan. Research Policy 2015

2. EU: Domestic Environmental Politics

Go it alone with nano risk regulation….

Germany 2010: ban all consumer products using nanosilver

French Environmental Code 2010: compulsory reporting

Netherlands 2012: call for urgent regulatory action on nanomaterials

Belgian Presidency 2009-2010: call for compulsory nanomaterials database

Sub – queries:

Differences/similarities in state-centric patterns ?

What explains transatlantic policy divergence?

The politics of environmental, health and safety risk regulation in the EU and the US

Nano-Risk Regulation & Governance; Nano-Risk Perceptions

34

Nano-Risk Policies: Convergence or Divergence?

United States • existing regulatory frameworks +

adjustments

• no labeling requirements

• patch-work at the national-federal level

• some risk assessment and management activities (e.g. FDA Regulatory science program)

• Lack of Congress support or leadership

European Union • existing regulatory frameworks +

adjustments

• labeling requirements (food, cosmetics)

• unified EU-level regulation: no data-no market

• intensive capacity –building: risk assessment and management (e.g.,FP7), NMs definition for regulatory purposes, regulatory frameworks revisited

• Parliament: ‘blueprint’ for regulatory

initiatives

Emerging Transatlantic Divergence!

35

What explains transatlantic policy divergence? Leading Theoretical Explanations

Economic interests?

(US competitiveness vs. EU sustainability)

Environmental NGOs?

(e.g. GMOs)

Domestic Environmental Politics & Policymaking Patterns

(Vogel, 2003, 2012)

(Justo-Hanani & Dayan. Global Environmental Politics 2016)

‘Alarm bells’?

(cultural risk perceptions? media pressure)

36

The precautionary approach (European Parliament 2009)

‘applying the Precautionary Principle is

about EHS research and regulating nano-

products before their release into the

market, as opposed to applying it after

release in the event that realistic and

serious risks are identified”.

Risk-based, case-by-case approach (White House memo, 2011)

‘regulation should be grounded in the

best available science and able to evolve

as scientific insights mature and the

body of evidence grows and evolves.

Consistent with current law, regulatory

agencies should take a science-based

approach to risk management.”

Risk vs. Precaution

(Schmitz & Simberloff, 1997)

42

Definitions

Alien Species A species, subspecies, or lower taxon occurring outside of its natural range and dispersal potential, including any part, gametes or propagule of such species that might survive and subsequently reproduce.

Invasive Species An alien species which becomes established in natural or semi-natural ecosystems or habitat, is an agent of change, and threatens native biological diversity

Introduction

The movement, by human agency, of a species, subspecies, or lower taxon outside its natural range. This movement can be either within a country or between countries.

43

Frequency of Biological Invasions

The Tens Rule, Williamson 1996

10% of alien species undergoing Introduction establish themselves in the new area

Of which 10% have become pests

It is difficult to predict biological invasions -

Preventive approach is needed!

44

How Do They Get to a New Place?

Variety of pathways: 3 types of introductions

45

Random introduction Intentional introduction

Directly to nature Captivation No specific purpose

Forestry

Nursery plants, food

crops

Mariculture

Biological control

Zoos, Botanical gardens

Research labs

Pet industry

Culture, ornamental plants

Private collections

"Stowaways "

Shipments of goods

Vehicles

Animals as vector

Tourism

Commercial Activity

Primary source for biological invasions

A significant portion of intentional introduction: pet industry, biological control, research

Legal and Institutional Framework

Convention on Biological Diversity, 1992

“Each contracting Party shall, as far as possible and as appropriate,

prevent the introduction of, control or eradicate those alien species

which threaten ecosystems, habitats or species”. Article 8 (h)

COP 6 Decision VI/23

“Invites the Food and Agriculture Organization of the United Nations,

the World Health Organization, the United Nations Development

Programme, the United Nations Environment Programme, the World

Bank and other development agencies to take this matter into account

when considering the impacts of land-use change, agriculture,

aquaculture, forestry, health and development policies and activities”

54

The European Union – Policy Innovation

New, regional dedicated regulation

Regulation on the prevention and management of the

introduction and spread of invasive alien species

(Regulation (EU) No 1143/2014 of the European Parliament and of the Council of 22 October 2014

What is innovative?

Union list – species of Union concern (open list, inclusion of

taxonomic groups of species )

Common criteria for risk assessment; research, monitoring

and surveillance by all relevant sectors and stakeholders

Core policy principles - prevention, eradication, management

55

The EU Food Security Policy Framework

‘The preservation of biodiversity is key for the production of food and

feed, and is therefore in the vested interest of farmers; ‘

‘Stresses the need to protect agricultural biodiversity in developing

countries in order to achieve food security; calls on the Commission,

therefore, to invest in agro-ecology in developing countries;’

‘Urges the Commission to establish, without delay and in accordance with

Article 4 of Regulation (EU) No 1143/2014, an accurate and

comprehensive list of invasive alien species which are of concern to the

Union’
