Those  who  have  evaluated  PES  interventions  in  practice  have  found  that  most interventions aiming to implement PES do not meet all of these criteria Sommerville et
al.,  2009.  Even  Wunder  himself  says,  that  “there  are  probably  very  few  true  PES” complying  with  all  five  elements  of  his  definition  Wunder,  2005,  p.  4.  Nevertheless,
since both scholars and practitioners of PES, such as CIFOR and the Katoomba Group’s Ecosystem Marketplace, use this definition, this is the definition that will be referred to in
this paper. Attempts to take the variety of PES schemes into account include a trial to develop
alternative  vocabulary.  Thus,  in  the  literature  one  can  also  find  the  terms  such  as compensation  and  rewards  for  ecosystem  services  CRES,  rewards  for  environmental
services, and payments for ecosystem services. Terminology that includes ‘compensation’ or  ‘rewards’  reflects  the  fact  that  benefits  are  not  necessarily  cash  payments.  They  can
include  non-financial  incentives,  including  the  provision  of  access  to  various  types  of capital human,  social,  natural,  physical,  and financial Noordwijk  and  Leimona,  2010.
The term ‘ecosystem services’ used by the Millennium Ecosystem Assessment MA refers to  positive  benefits  that  people  obtain  from  ecosystems.  Unlike  environmental  services,
this  also  refers  to  provisioning  services  such  as  food,  fibre,  and  timber  Millennium Ecosystem Assessment, 2005, p. V, 27; Sommerville et al., 2009. There are also attempts
to classify different categories of PES, such as payments for watershed services PWS, or to categorize them according to their scale including regional and international payments
for  environmental  services.  Nevertheless,  the  term  payments  for  environmental  services remains the most widely recognized one. Therefore, it will be used for the purposes of this
paper.
Environmental services are commonly classified into four categories: 
Carbon sequestration: aims at the long-term storage of carbon in woody biomass and soil organic matter. As buyers and sellers can be located anywhere in the world, it is
considered  a  ‘global’  market.  An  example  is  an  electricity  company,  which  pays farmers to plant and maintain additional trees.
 Watershed protection: aims at providing an adequate amount of good quality water as
well as at controlling flooding, erosion, and soil salinization. Since buyers and sellers live in the area that is to be protected, it is considered the most regional or local ES.
An  example  is  downstream  water  users  private  companies  or  households  that  pay upstream farmers for adopting land use that limit deforestation, flood risk, andor soil
erosion.
 Biodiversity protection: aims at conserving areas that maintain biodiversity. This can
originate  at  the  international  level  or  at  a  more  local  level.  The  sellers  have  to  be situated in the protected area while this is not necessarily the case for the buyers. An
example  is  when  conservation  donors  compensate  local  people  for  protecting  or restoring areas with large biodiversity.
 Landscape beauty: aims at maintaining natural sources of inspiration and culture, as
well as commerce by eco-tourism. As with biodiversity protection, this ES can take place at the international or on a more local scale as buyers can, but do not need to be,
located in or close to the protected area. An example is a tourism operator that pays a
local community for not hunting in an area used for tourists’ wildlife viewing. While some of these services might be traded together e.g. protected biodiversity is
also attractive for tourists, there can also be trade-offs between these services e.g. a fast-

growing  plantation  that  maximizes  carbon  sequestration  might  not  be  very  biodiversity- rich Wunder, 2005, p. 2.
There is a large range of concrete design possibilities for PES. Schemes not only vary according to the type of environmental service offered, but also in terms of coordination
and  ways  of  financing,  scope,  forms  of  land  use,  forms  of  payments,  among  others. Referring again to the types of the environmental services, PES can either be area-based or
product-based.  In  area-based  schemes,  the  contract  applies  to  land  or  resource  use according  to  a  pre-agreed  number  of  units,  usually  hectares.  For  example,  watershed
services providers are usually paid according to the size of the land that is included in the scheme. In product-based schemes, the buyer pays a green premium on top of the market
price of the product being sold. For example, a premium may be charged for coffee that has  been  produced  under  sustainable  land  use.  ES  can  also  be  classified  according  to
whether  they  are  based  on  material  flows,  such  as  watershed  services,  or  on  internal environmental  quality,  such  as  biodiversity  and  landscape  beauty  Wunder,  2005,  p.  7;
Noordwijk, 2005, p. 7.
Regarding  coordination  and  financing,  PES  can  be  public,  private,  or  donor-led schemes. Public schemes are managed and financed by the state, usually through general
taxes. They  are  often  large,  nationwide  programmes  and  tend  to include  side  objectives. The  government  takes  over  the  role  of  the  buyer  and  buys  ES  on  behalf  of  the  public.
Private  schemes  tend  to  be  smaller,  focusing  on  a  local  area  sometimes  only  covering fewer than five providing families. Users and buyers of ES
– private companies or private households
–  pay  providers  and  sellers  of  the  services  directly.  Donor-led  schemes  are encouraged and financed by international donors. They tend to support local, small-scale
projects, often within larger initiatives covering  more than one country see e.g. RUPES and  PRESA  in  Chapter  4.1.  Schemes  can  also  combine  public,  private,  andor  donor
support. Donor-led programmes often aim to increasingly incorporate private companies, with  the  objective  that  in  the  long  term  they  will  buy  the  ES  from  either  individuals  or
communities.  Public  schemes  can  be  supported  by  international  donor  grants  or  advice Wunder, 2005, p. 8.
The  forms  of  land  use  covered  by  PES  contracts  can  be  use-restricting  or  asset- building. If they are use-restricting, the provider has to conserve the protected area and is
not allowed to use it in any way. Providers are paid the opportunity cost. In asset-building schemes,  on  the  other  hand,  providers  are  paid  for  restoring  an  area  by  improving
environmental services, e.g. by applying more sustainable production practices. Regarding the  kind  of  payment,  providers  can  be  paid  in  cash  or  in  kind,  as  well  as  directly  or
indirectly.  In  use-restricting  schemes,  compensation is  usually  in  the form  of  direct  cash payments, while in asset-building schemes direct compensation can also take the form of
in-kind payments. These may include the direct provision of planting materials and tools, skills training andor technical assistance, and, more indirectly, the improvement of health
and educational services, local infrastructure, market preferences, or land tenure security. The improvement of services is often part of programmes where whole communities act as
providers instead of individuals. Different forms of payments can also be combined within one scheme. For example, a provider might be paid a cash benefit and additionally receive
training  and  the  necessary  tools  for  changing  land-use  practices  Wunder,  2005,  p.  7; Noordwijk,  2005,  p.  7.  The  differentiation  between  use-restricting  and  asset-building  is
rel
evant in regards to the scope for building sustainable “exit doors” for beneficiaries from cash  transfer  schemes.  Since  “use-restricting”  by  definition  limits  the  creation  of  new
economic activities, “asset-building” allows for the creation of new sustainable jobs and innovative value aggregation chains see section 5.2.2 in this document.
