environmental protection accounts, and exchange of environmental
data between different stakeholders.
The hard work and research undertaken within the NIS by the different
think tanks have resulted in concrete activities and achievements as well as
projects for which the NIS is called upon to invest more according to a
roadmap already identified by the experts. Indeed, the transfer to a new base
year for a new generation of national accounts considering the main
recommendations of the 2008 SNA requires the mobilization of a large body
of data from different sources such as surveys, administrative data, new
surveys, etc. Some information calls for preparatory work and budgetary
programming, as well as a strong commitment from all stakeholders, because
this project is national in nature and far exceeds the competence of the NIS.
Despite all of these constraints, the NIS, in partnership with the main partners,
can achieve most of the set objectives, including:
 A new base year of accounts has been defined (2015-2016) and work
has progressed to develop accounts according to this new base year
and well-identified roadmap;
 The recommendations of the United Nations 2008 SNA have been
thoroughly reviewed and concrete steps have been taken to ensure the
best possible transition to National Accounts in compliance with this
system;
 A demand decomposition approach has been implemented and work
is well in advance;
 The calculation of the regional GDPs for the chosen year (2013) has
been finalized and validated by the experts of the NIS at first, and then
revalidated by other experts, mainly academics who work and master
these aspects. The main conclusion from all the work on this file is that
the first sector results are consistent with what is observed on the
ground;
 The water satellite accounts for 2010 and 2015 have been developed
to measure imbalances between limited potential and exponential
demand;
 The NIS has produced a publication on environment statistics which
aims to improve the quality and scope of data with dissemination of
key statistics in a single medium.
The work of relining the national accounts and considering the
recommendations of the SNA 2008 is an absolute priority not only for the NIS,
but also for all economic and social actors, to better reflect the economic
reality and the weight of the sectors in the national economy. Highly sensitive
issues, such as the informal economy and the regionalization of GDP and VA,
have been treated and rigorously apprehended for the first time in Tunisia.
The NIS will continue some activities for a period of two to three years
