The GEF funded project
Development of the Methodology and Arrangements for the GEF Transboundary
Waters Assessment Programme (TWAP)
w
as approved by the GEF in January 2009.
The project
is being
implemented by UNEP DGEF and executed by UNEP
-
DEWA together with partners. The
TWAP
Inception meeting was held in June 2009.


The main objective of the project is to develop:

(i) the methodolog
y for assessment/results tracking for each of the five categories of transboundary water
systems (transboundary groundwater; transboundary lakes/reservoirs; transboundary river basins; Large
Marine Ecosystems (LMEs); and open ocean areas) under the TWAP;

(ii) a partnership among organisations; and

(iii) the arrangements needed to conduct a baseline transboundary waters assessment that may be
conducted following completion of the MSP.

Five technical Working Groups (WGs) have been established, at the leve
l of water systems, for the
development of the methodology and for development of institutional arrangements for the
implementation of TWAP. In addition to these, an Information Management and Indicators Working
Group
(IMAI
G) has been established, which ha
s representatives from the five water system WGs, and

consists of
three Correspondence
(sub

)
Working Groups i.e. Governance/Socio
-
economic, Data
Management/Modelling/GIS and Publication/Communication.


Data Management/Modelling/GIS Working group (DMMG)


T
he proposed assessment methodology will
be
science
-
based
and
connect
ing

human
-

and climate
-
induced
changes to freshwater systems at the drainage basin and aquifer level, linked with the human and natural
forces driving changes in marine areas. The methodol
ogy will make use of relevant regional and global
databases and indicators. More specifically, this will include an International Waters
i
ndicator framework,
based on process indicators, stress factors, and environmental status indicators. Suites of indic
ators for
environmental state and trends, as well as anthropogenic and natural driving forces of changes in these
systems, will be
identified or
developed and used to establish initial baseline conditions, and for future
quantitative evaluation of the chan
ging states of these ecosystems and associated pressures.


The
main
objective
s

of the IMAIG/DMMG
correspondence group are

to select a set of indicators that will
allow for the global assessment of all five water systems and will ensure that linkages among
them are
taken into consideration, and develop a proper data and information management system in support of
TWAP while building on already available authoritative global databases and systems.


DMMG ToR


1) The DMMG is to propose and develop key indicato
rs at the water system level, from hilltops to ocean,
and covering state, process indicators, stress factors and taking into consideration the scientific,
socioeconomic and governance issues with overarching impairment of ecosystems goods and services.
The
se indicators need to be related to ongoing regional and global processes and related political goals
and targets such as the World Summit on Sustainable Development (WSSD) and the Millennium
Development Goals (MDG). A good reference is the GEF project
“En
hancing the use of science in
International Waters projects to improve project results”
.

The following cross
-
cutting issues have been identified by the TWAP working groups:

a) Quantity of water

b) Climate change to be narrowed down to vulnerability of the
changes caused to the water system. (Each
WG is to consider producing a map of water bodies in relation to the changes caused by climate change).
Document IPCC Report No. 6 Climate Change and Water was recommended as reference

c) Nutrients
-
nitrates

d) Biol
ogical productivity

e) Pollutants
-
mercury


2) The DMMG is also to define a data management methodology and system that will support the TWAP
and its Working Groups, and incorporate access to existing global databases containing processed and
validated data

form authoritative sources. Use can be made of existing data systems in UNEP, UNESCO
and other partners (GEO Data Portal, WHYMAP, IGRAC/GGIS etc).


3) In addition to the data sets and indicators themselves, the DMMG is also to consider a common
approach
for the scoring and presentation of indicators taking into consideration the following options:



Numeric values

(Quartile/Pentile)



Direction arrows



Stop lights



Maps


Proposed activities:



Integrate and map the defined

assessment units/boundaries of five wate
r systems
.




Collate
the inventor
ies

of major
existing
data

sets

and sources
, models and networks, based on the
input and contributions from the five water system WGs
.



Make an overview of
data gaps
and shortcomings
that prohibit
proper
indicator development

and
presentation, and summarize identified
data sources
and methods
that can support agreed
indicators

(proxies, models etc.)
.



Identify and/or develop key indicators and/or aggregated indices to inform management and
policy information needs
.



Identify and
/or develop set of indicators for interlinkages among the five water systems
.




Prepare a proposal for a TWAP data and information management system, making use of existing
regional and global databases and information systems
.



Compare and relate data and i
ndicators with those used in other regional and global processes
(e.g., UNGA Regular Process, World Water Assessment Program)
.


Proposes Outputs:



Overview of
assessment units/boundaries of the five water systems
.



Combined i
nventory of relevant data, source
s, ongoing programmes and available methodologies



Summary of identified
opportunities for sharing data and information, data needs and gaps



Set of common indicators, addressing the interlinkages among the five water systems and
covering state, process, so
cio
-
economic, governance, and stress factors with overarching
impairment of ecosystem goods and services.



List of key indicators/indices for communication purposes and to inform identified management
and policy information needs



Proposal for a TWAP data a
nd information management system (FSP phase), allowing a proper
and efficient assessment and building on available databases and systems.
