Project "Defence and valorization of biodiversity in Niger by means of
environmental education programmes and operative strategies": state of
the art and preliminary results
The
project, supported by Comune di Milano, started on April 1st,
2011
and it is still in progress. It is supervised by the Dipartimento di
Scienze
Animali dell’Università degli Studi di Milano, in
collaboration with the
Italian ONG “Terre Solidali” and with the Niger
Park Direction. The specific
aim of the project is the valorization of biodiversity in the
transition area
of the Biosphere Reserve of Park W (at the border between Niger, Benin
and
Burkina Faso), through the reinforcement of the ability of the actors
(Park
guards, local communities, farmers, etc.) involved in biodiversity
conservation
and set up of operative strategies of natural resources.
The
following activities have
already been carried out: a) formation of Park rangers for correct
spread of
information about biodiversity management and environmental education;
b) contribution
to the preparation of a Visitor Centre in the W Park; c) production of
informative material; d) monitoring wild-domestic animal spatial and
sanitary interactions
in areas within and around Pak W, using GIS technologies and parasite
analysis.
We set up a specific database, able to catalogue and geo-reference all
spatial
and sanitary information collected, and to graphically display them
selecting
the portions of information required. Using this tool, preliminary
analysis of
these data are currently being carried out.
At
the moment, we are carrying
out the following further activities: a) formation of farmers about
animal
health issues, on the basis of the results gathered in the first phase
of the
project; b) educational programmes on environmental protection for
children in
school age in the villages of the area around the W Park.

Optimal control of culling in epidemic models for wildlife
Optimal control theory is applied to a system of ODEs modeling
infectious diseases in wildlife. Culling is introduced as a strategy to
eradicate the infection, and plays the role of control variable. The
optimization criterion is to minimize both the number of infected
animals and the cost of culling effort. Different forms of the
objective cost function are considered, including quadratic control and
linear control, and in the latter case the possibility of singular
control is investigated. The optimality systems are solved numerically
and results illustrate which is the optimal strategy in different
scenarios, depending on the virulence of the disease.

Mathematical approaches to infectious diseases control
Infectious diseases
are a leading cause
of death worldwide, and the south of the world is the most
affected part. Therefore reducing the disease burden means
also
reduce the gap between north and south of the world. In this
direction, mathematics can help to understand and describe
the
mechanisms of spread of infectious diseases. In this talk we
will
mention two useful mathematical approaches: the bifurcation
theory and the optimal control theory. In particular, based on
two recent papers [1,2], we focus on vaccination
strategies
to fight vertically transmitted diseases in both
the cases
of constant and periodically transmitted diseases.
Theoretical
scenarios, analytical results and computer simulations
are
provided. The findings are used to simulate simple scenarios
for
some real cases.

Analysis of time series satellite imagery to monitor vegetated ecosystem dynamics in Sahel
Recent
studies on
Sahel have shown an overall greening which demonstrates the recovery of
these
areas with respect to the strong drought of the ‘60s. Despite
a recovery of the
vegetation compound in those areas, several humanitarian crises, which
are
related to natural resources, have been reported in the region during
the last
decade. Further studies are needed to address different aspect of
ecosystem
dynamics in order to highlight anomalous changes that might cause
possible
critical situations. The present research aims to contribute to the
understanding of climate/human impact on the status of pasture
vegetation and
agriculture in the Sahelian region from the late 90s to current days.
The dynamics of
vegetated ecosystems in the region have been analyzed using time series
of SPOT
VGT 1-Km NDVI data and FEWS
