Appendix 14: Approach to estimation calculations
GDP: GDP is taken as criterion the first approach. The overall expenditures
were estimated by correlating the overall GDP of all 165 countries to the swn of
the specific countries' GDP and multiplying it with the known expenditures (for
financial assistance received, contributed, and domestic expenditures
respectively). The overall expenditures for the conservation of PGRF A,
extrapolated for 165 countries, can be calculated as follows:
165
165
:L GDP x
:LExpx = n~1
X :LExpx
(A. 1)
n=1
:L GDP n=1
n=1
whereby:
I ExPx is the overall extrapolated expenditures for all countries (n= 1 ... 165) in one
of the three categories (financial assistance received, financial assistance
contributed, and domestic expenditures);
x defines the countries eligible for the relevant category (financial assistance
received, financial assistance contributed, and domestic expenditures);
IGDP is the total of GDP for all countries (n=1...165); or
I GDP is the total of GDP for those countries only, belonging to the category
calculated (n=l...x);
I Expx is the swn of expenditures of the countries eligible (n= 1... x).
Accessions: The ex situ conserved accessions were used as criterion in the
second approach based on the assumption that the lion's share of national
expenditures of the conservation of PGRF A is made in the area of ex situ
conservation. The overall expenditures for the three categories can be extrapolated
by calculating the ratio of all ex situ conserved accessions to the accessions
conserved by the 39 countries and multiplying it with the known expenditures of
these countries.
