Summary of the impact
The research at the University of Reading has developed statistical
methods and information systems for two global monitoring systems for
elephants: MIKE (Monitoring the Illegal Killing of Elephants) and ETIS
(Elephant Trade Information System). The systems provide quantitative
evidence, via bias-adjusted indicators, on global and regional trends in
the illegal killing of elephants and the illicit ivory trade. This
evidence forms the substance of reports discussed at the Convention for
International Trade in Endangered Species of Wild Fauna and Flora (CITES).
Based on this information, CITES has adopted decisions to introduce
interventions targeting over 20 countries in Africa, Asia and the Middle
East aimed at curbing the illegal ivory trade. As well as providing the
underpinning data that has informed international policy on illicit
trading of this threatened species, the evidence has also helped raise
public awareness of the threats to elephants as well as improving
monitoring systems and increasing their reach.
Underpinning research
Background
CITES, a United Nations convention administered by the United Nations
Environment Program (UNEP), is the global regulatory body for
international wildlife trade. In 1989 CITES banned all trade in elephant
products, but in 1997, at the 10th meeting of the CITES
Conference of the Parties (CoP) agreed to a tightly regulated one-off sale
of ivory from three Southern African countries to Japan. This was a
controversial decision but it led the CITES Parties to mandate two global
monitoring systems for elephants, MIKE and ETIS. Part of the remit of
these systems was to provide evidence on levels and trends in the illegal
killing of elephants (MIKE) and the illegal trade in ivory (ETIS) and, as
far as possible, relate these results to decisions taken about protecting
elephants under the Convention. Both programmes are required to provide
comprehensive analyses to meetings of the Conference of the Parties (CoPs)
every two to three years and update reports to the annual Standing
Committee meetings to support decision-making for elephants under the
Convention.
The MIKE programme was designed as a site-based initiative to collect
elephant mortality data, especially the number of illegally killed
elephants, at selected sites throughout elephant range in Africa and Asia.
The focus of ETIS was on seizures of illegal ivory trade made by law
enforcement agencies across the world. However, when these programmes were
first set up, the statistical methods required to analyse the data were
not in place.
Involvement of the University of Reading in MIKE and ETIS
ETIS was to be based on an earlier system called BIDS (Bad Ivory Database
System) that was run by TRAFFIC International, the wildlife trade
monitoring network. In 1997 Mr Robert Burn (then of the Statistical
Services Centre, University of Reading), was contracted to carry out a
review of BIDS and advise how it could be adapted to meet CITES
requirements. He presented this review at a MIKE/ETIS technical design
workshop in 1997 and identified the major analytical challenges.
Subsequently he was invited to sit on the Technical Advisory Groups for
both MIKE and ETIS and to carry out a number of consultancies for both
monitoring systems, including: the design of the site selection protocol
for MIKE; baseline analysis of the MIKE data for the 12 to 14th
CoPs (between 2002 and 2007); developing the ETIS database; and carrying
out comprehensive analyses of the ETIS data for the 12th to 15th
CoPs (between 2002 and 2010). The methodology of these early analyses were
largely ad-hoc and carried out to meet very short deadlines. Even so, the
very first analysis of the ETIS data by Mr Burn, presented to the 12th
CoP in 2002, indicated the importance of China in the illegal ivory trade
at a time when the focus was on Japan. Partly as a result of these changes
CITES allowed China to participate in the tightly controlled sale of ivory
in 2008.In 2004, Dr Fiona Underwood joined the Statistical Services Centre
and participated in some of the above work. She had previously been
involved, together with Mr Burn, in designing the MIKE data analysis
strategy published in 2003.
In 2008, Mr Burn and Dr Underwood (by then a lecturer at the University
of Reading) were contracted by MIKE to develop methods for an in-depth
analysis of the MIKE data. This effort resulted in a research paper with
the MIKE data analyst (reference 3.1) that described the methodology and
applied it to MIKE data on elephant mortality from 2002 to 2009. In 2009,
Dr Underwood and Mr Burn (by then a visiting Research Fellow at the
University of Reading), with TRAFFIC sought funding for a 3-year research
project aimed at ensuring the long-term sustainability of ETIS through the
further development of the analytical framework, new database software to
support the system, formalised standard operating procedures and training
materials to enhance global participation of the CITES Parties. One of the
technical outcomes of the project was a scientific paper (reference 3.3)
describing the new analytical methods and the results from analysing ETIS
data from 1996 through 2011. A comprehensive report was issued to the 16th
CITES CoP as a formal agenda item (reference 3.4), showing illegal ivory
trade trends, identifying key countries in the illicit trade and
describing trade routes and dynamics driving the trade. This report led to
a series of actions directed at specific countries to curtail the illegal
trade in elephant ivory.
Statistical research
The key statistical issue for both MIKE and ETIS is that they aim to
monitor and report on covert and illegal processes, which cannot be
monitored using standard statistical methods. The monitoring is carried
out by law enforcement agencies that intervene in, rather than passively
observe, the process being monitored. Furthermore, law enforcement
agencies differ in their ability to intervene and to report their
interventions to the relevant monitoring system. This variability is
difficult to measure but must be accounted for so that estimates of
illegal activity can be compared between countries and over time. There
had been very little statistical research into these problems prior to
this work. A further aim of the research was to produce simple indicators
that can be used to inform policy makers about trends.
For both monitoring systems, proxy variables were identified or developed
that could account for differences in detecting and reporting illegal
activity over time and between countries or sites. These included
background variables relating to corruption and development, and variables
specific to MIKE and ETIS.
For MIKE, the indicator PIKE, the Proportion of Illegally Killed
Elephants (of all elephant carcasses found on patrol) was developed.
Bayesian hierarchical models were used to capture the structure of the
data, trends in PIKE were described and the relative role of
poaching in individual sites and countries was estimated.
For ETIS, a new
modelling framework was developed that extended the ideas in MIKE by
modelling the underlying process by which data enter ETIS using Bayesian
hierarchical latent variable models. Proxies that describe differences in
the latent variables (reporting and seizure rates) between countries and
over time were identified and tested. A multivariate negative binomial
model enabled different dynamics to be considered for trade in raw and
worked ivory in three weight classes. Smoothed bias-adjusted relative
indicators of the number of transactions by country, year and ivory class
were produced and aggregated to give a global Transactions Index and
Weights Index. The framework was applied to over 11,000 records of illegal
ivory seizures from 1996 to 2011 from 68 countries. The headline result is
that globally illegal ivory trade activity in 2011 has more than doubled
since 2007, and tripled since 1998.

Details of the impact
Informing international policy
The main impact of the research has been to provide the substantive
quantitative data that has informed international policy decisions both on
the regulation of trade in elephant products and on law enforcement
regarding the illicit ivory trade and the illegal killing of elephants.
Research findings (references 3.1 and 3.3) formed the main evidence in
mandated reports by MIKE (reference 3.2) and ETIS (reference 3.4) to the
last two CoPs respectively. These reports provide the evidence framing
much of the discussion between non-governmental organisations, governments
and pressure groups. For example, at the 15th CoP in March
2010, partly as a result of the MIKE report, the decision was made not to
allow regulated sales of ivory from Tanzania and Zambia.
At the 16th CoP in Bangkok in March 2013, there was "unprecedented
uptake of the ETIS results... and motivation to seriously tackle
outstanding problems for the benefit of elephant conservation" (as
reported in Pachyderm magazine). The ETIS report identified three
groups of countries most heavily implicated in the trade, including
Thailand, the host country. At the opening ceremony the Prime Minister of
Thailand announced that her country would be pursuing "the goal of
putting an end to ivory trade and to be in line with international norms".
CITES adopted a separate decision for each of the three groups of
countries identified by ETIS, impacting over twenty countries from Africa,
Asia and the Middle East. These decisions include the creation of a CITES
Ivory Enforcement Task Force to review law enforcement strategies for
combating illegal trade in eight countries in partnership with
international organisations such as the World Bank, the World Customs
Organization, the United Nations Office on Drugs and Crime and INTERPOL.
Raising
public awareness
The research outputs, in particular the bias-adjusted indicators, have
been used by environmental organisations to raise awareness of the
increasing threat to elephants from the illegal ivory trade. For example,
a major report Elephants in the Dust — The African Elephant Crisis
by United Nations Environment Programme, CITES, International Union for
Conservation of Nature (a global environmental organisation) and TRAFFIC,
drawing together all the recent research on elephants, was released at a
press conference at the 16th CoP in March 2013. The statistical
contributions of this research form much of the evidential basis both for
MIKE and ETIS. The headline result of the ETIS analysis was the primary
lead in a plethora of news stories generated by the international media.
The PIKE indicator is also referenced in the World Wide Fund for Nature
Crime Scorecard produced in 2012.
Improving monitoring systems and informing best practice
Both monitoring systems have been refined and improved as a result of the
research. For example, in developing the analytical framework for ETIS it
became necessary to restructure the ETIS database to ensure that the data
being collected are of the highest quality and the most relevant for the
required analytical purposes. The fields in the database were therefore
revised and data collection methodologies improved. In particular, an
online, government-restricted mechanism enabling countries to directly
enter and access data on illegal ivory seizures data is expected to be
launched by the end of 2013. This is a significant development that will
impact all countries that report to CITES (typically about 80 countries
from Europe, America, Africa, Asia and Australasia report seizures to
ETIS).
More generally, the long-term involvement of Mr Burn and Dr Underwood in
guiding the development of MIKE and ETIS since their inception has led to
a strong statistical underpinning to the two monitoring systems and has
helped shape their overall direction and identify their limitations. This
influence has, in part, been made via the MIKE-ETIS Technical Advisory
Groups (a group of experts working in elephant conservation and the
illegal ivory trade), where the research methodologies and results have
been presented and discussed.
During the period of the Darwin Initiative project, research
methodologies, results and the new database were presented in 2012 to the
United Nations Environment Programme's fourth African Elephant Meeting
held in Nairobi, to the 62nd CITES Standing Committee and to a
training event for African CITES Parties involved in reporting ETIS data
to CITES. Mr Burn and Dr Underwood also initiated a workshop on the
drivers of the illegal ivory trade, the results of which have informed
UNEP's Elephants in the Dust report.
In a press release from TRAFFIC in June 2012, Tom Milliken, who manages
ETIS, stated: "Since 1997, our long-term collaboration with Bob Burn
and Dr Fiona Underwood from the University of Reading has progressively
scaled up the science behind ETIS and made it a `best practice',
state-of-the-art monitoring tool for the global conservation community".
During the 62nd CITES Standing Committee, the Secretary General
of CITES also publicly recognised Mr Burn's contribution to the scientific
underpinning of MIKE and ETIS.
MIKE and ETIS are unique global databases. Reading statisticians are the
only researchers who have been given access to the raw ETIS data and,
until 2010 (when Mr Burn stood down from the MIKE Technical Advisory
Group), the only statisticians who had been given access to the MIKE data.
