History of the project
The ILCA / ODEM Project
The
International
Livestock
Center
for
Africa
ILCA/CIPEA
was
created
in
1975,
as
the
13
th
research
center
of
the
Consultative
Group
on
International
Agricultural
Research
–
CGIAR
–
which
funded
research
centers
promoting
the
"green
revolution".
It
established
itself
in
Mali
in
1979,
in
collaboration
with
the
Institute
of
Rural
Economy,
IER.
In
association
with
the
Operation
for
Livestock
Development
in
the
Mopti
Region
–
ODEM
–
and
funded
by
the
World
Bank,
the
CIPEA-IER/ODEM
teams
started
a
very
ambitious
research
and
development
project
which,
in
the
productivist
approach
in
fashion
at
that
time,
was
aimed
at
'modernizing'
livestock
breeding
in
the
5
th
region
of
Mali
in
order
to
make
the
region a pole of animal production in the area.
Our mandate was threefold:
•
To
conduct
a
fine-scale
study
of
the
rangelands
of
the
Inner
Delta
of
Niger
(fig
1),
as
well
as
transhumance
during
the
rainy
season
and
cool
dry
season
on
the
left
bank,
reaching
westwards
to
the
Serpent
valley
and
northwards
up
to
the
Mauritanian border.
•
To
conduct
a
study
of
the
pastoral
organization
of
the
land
(territories,
transhumance
paths
...),
and
of
conflicts
between
pastoralists,
fishermen
and
farmers related to the uses of natural resources.
•
To formulate proposals for the development of livestock productivity.
The
means
at
our
disposal
were
exceptional:
a
budget
of
more
than
one
million
dollars,
a
fleet
of
vehicles,
a
twin-engine
aircraft,
a 1:50 000 photographic coverage in Infrared Color, commissioned to the French National Geographic Institute, IGN.
The
human
resources
were
equally
considerable:
some
thirty
Malian
and
international
researchers
and
collaborators
divided
into
several teams:
•
A team of ecologists under the direction of Pierre Hiernaux, Mohamed Idrissa Cissé and Lassine Diarra.
•
A
team
responsible
for
studies
and
for
the
mapping
of
pastoral
land
tenure
under
the
direction
of
Salmana
Cissé,
Samba
Soumaré
and Jérôme Marie.
•
An team for aerial surveys (including cattle counting) under the direction of Kevin Milligan, David Bourn and William Wint.
•
A
team
responsible
for
the
study
and
implementation
of
a
reform
of
territories
and
uses
that
regulate
access
to
natural
resources.
This work was directed by Salmana Cissé, Alain Rochegude (a lawyer) and Jérôme Marie.
•
Finally,
a
team
based
at
ILCA
headquarters
in
Addis
Ababa,
in
charge
of
mapping.
Mark
Haywood,
his
director,
made
several
visits
to
the
fields
with
Pierre
Hiernaux.
He
realized
the
whole
photo-interpretation,
defined
and
coordinated
the
drawing
of
the
cartographic
system.
Land
tenure
crews
charged
with
registering
the
leyde
boundaries,
pastoral
trails,
and
resting
camps
worked
directly on the 1:50 000 topographic background maps developed by Mark Haywood.
This
resulted
in
a
report
entitled
"Seeking
a
solution
to
the
problems
of
animal
husbandry
in
the
Inner
Delta
of
the
Niger
in
Mali",
handed over to the Government of Mali and the ODEM in March 1983. The five volumes (1100 pages) dealt with :
1
.
Rangelands in the study area (their floristic composition, ecological conditions, production, etc.)
2
.
The distribution and density of livestock in different seasons obtained by systematic aerial surveys.
3
.
Geographical
and
socio-economic
monographs
covering
all
the
leyde
(Fulani
pastoral
territories
in
the
Delta),
dealing
with
villages, population, the organization of transhumance, land conflicts, etc.
4
.
A
legal
analysis
proposing
solutions
to
solve
conflicts
between
pastoralists,
fishermen
and
farmers.
In
particular,
we
advocated
the
replacement
of
leyde
by
agro-pastoral
units,
territorial
communities
headed
by
an
elected
council
whose
competence
would
be to regulate the use of resources (land, water, pastures, etc.) among the various holders of rights.
These reports were accompanied by detailed maps in three layers:
•
The
maps
of
the
Niger
Inland
Delta
rangelands
(27
maps
at
1:50
000
scale
in
80x50
cm
format).
But
also
the
map
of
the
rangelands
of
the
'Delta
mort'
and
the
Office
du
Niger
(31
maps
in
the
1:
100
000
format
40x28cm)
and
the
maps
of
the
continental rangelands to the West and North (6 IGN topographic maps 1: 200,000).
•
Pastoral
land
mapping
of
the
Inland
Delta
of
the
Niger
covering
the
31
leyde
(Fulani
pastoral
territories)
of
the
Delta.
This
cover,
rigorously
superimposable
to
the
previous
one,
bore
the
detailed
hydrographic
network,
the
relief
elements
(hills
or
"togge"
),
the
villages
and
hamlets
cultivated,
the
pastoral
tracks
inside
the
Delta
(over
3,600
km)
pastoral
gîtes
(over
1,000),
toponymy,
land
disputes over lodges, trails or
leyde
boundaries.
•
Maps
of
agricultural
land
use,
comparing
1952
and
1974/75
(Haywood
M.
1981.
"Evolution
of
land
use
and
vegetation
in
the
Sudano-Sahelian zone of the ILCA project in Mali", Doc. Working Group 3, ILCA, Addis Ababa, 187 p.).
This work was not implemented and its results were never published, for several reasons:
•
Implementation
would
have
required
the
establishment
of
relations
between
the
populations
and
the
administrations
concerned
on
a
decentralized
and
democratic
basis,
which
was
not
the
case
at
the
time.
The
decentralization
that
took
place
under
the
Third
Republic,
which
led
in
1999
to
the
creation
of
rural
communes
and
the
election
of
municipal
councils,
now
offers
more
favorable
political
conditions
for
the
local
management
of
natural
resources,
as
our
study
advocated
at
the
time.
Despite
the
success
of
the
two experimental units, in 1983 the Malian political power was not ready for such a radical reform.
•
ILCA
engaged
in
the
study
only
at
the
urgent
request
of
the
World
Bank.
No
provisions
had
been
made
for
a
publication
beyond
the
delivery
of
the
reports
and
maps
to
ODEM
as
specified
in
the
contract.
Besides,
such
a
publication
would
have
been
at
odds
with
the
ILCA
policy
in
those
days,
which
was
more
focused
on
animal
production
development
projects.
Our
concern
about
pastoral land tenure was largely misunderstood by our supervisors at that time....
•
But
the
main
reason
was
our
inability
to
perform
syntheses,
or
modeling
and
spatial
analysis
operations
on
such
a
mass
of
data
in
the
absence
of
powerful
computing
tools.
In
1983,
computers
still
used
heavy,
slow
and
expensive
systems.
GIS
was
virtually
non-existent
and
satellite
remote
sensing
was
in
its
infancy
(SPOT,
for
instance,
had
not
yet
been
launched).
Pierre
Hiernaux,
for
example,
treated
his
phyto-ecological
observations
with
punch
cards.
When
Mark
Haywood
wanted
to
quantify
the
area
of
the
«bourgoutières»
in
the
Delta
in
1983,
he
had
to
cut
out
the
plots
representing
this
plant
species
formation
and
then
weigh
the
paper pieces to deduce the area!
The creation of the Geographic Information System DELMASIG
However,
the
project
archives
were
carefully
kept,
and
in
the
early
1990s,
with
the
authorization
of
ILCA
–
which
was
not
interested
in
the
study
anymore
–
a
first
attempt
was
made
to
publish
the
maps
with
the
active
help
of
colleagues
of
the
Institute
of
Livestock
and
Veterinary
Medicine
for
the
Tropics,
IEMVT
(now
a
department
of
Center
for
International
Cooperation
in
Agronomical
Research
toward
Development,
CIRAD).
The
exorbitant
cost
of
this
publication
(about
1
million
francs
or
170,000
euros)
caused
the
project
to
fail.
It
became
evident
that
only
the
realization
of
a
GIS
would
make
these
data
accessible
and
provide
the
syntheses
that
we
had
not
been
able
to
carry
out
at
the
time.
Starting
in
1997,
thanks
to
François
Cuq’s
friendly
help,
Jérôme
Marie,
the
team's
geographer,
was
able
to
work
full-time
at
the
Géosystèmes
laboratory
of
the
CNRS
on
Arc
Info
software
in
order
to
model
the
data
collected.
A
small
team
was
set
up
with
Pierre
Hiernaux,
Mark
Haywood
(who
digitized
all
the
rangeland
maps),
Isabelle
Louise
Bisson,
a
student
and
database
specialist,
Emmanuel
and
Jacqueline
Giraudet,
CNRS
engineers,
Alain
Trouvé,
a
mathematician
in
Paris13
-Villetaneuse
and
Yu
Yong,
a
computer
scientist
of
the
University
of
Shanghai
then
registered
for
a
post-
doc in Paris 13.
The original project was enriched with new data:
- Water levels recorded until 2015 in order to model the flooded areas.
- The areas cultivated in 1952, 1975 and 1989, making it possible to relate rice farming to the flood
- The new territorial organization of Mali in order to put the analyses within the framework of the rural ‘communes’.
-
Landsat
satellite
images
(since
1984)
to
verify
the
extent
of
the
flooded
surfaces
for
the
different
flood
heights
and
to
cross
the
results
of
the
satellite
images
analysis
with
our
own
3D
model
of
the
Delta
basins.
This
model
was
also
enriched
by
the
thousands
of
altitude ratings created by the IGN for the Niger River Mathematical Model.
-
In
2014,
Pierre
Hiernaux
and
Matthew
D.
Turner
were
able
to
return
to
the
Inland
Delta,
revisit
the
sites
described
between
1979
and 1983 and document the dynamics of the vegetation for a possible updating of the vegetation map.
It
is
therefore
the
evolution
of
this
GIS
now
developed
under
ARC
GIS
and
called
"DELMASIG"
–
for
SIG
DELTA
inside
MALI
–
that
Jérôme
Marie
and
Pierre
Hiernaux
have
decided
to
make
accessible
to
the
scientific
community
by
creating
a
dedicated website with these data and maps.
