• Sense of complexity
• Comprehensive frameworks such as [Fisher et al
(2014)] make things harder to overlook, [and] they
dictate what is on the agenda. This leads to a central
limitation: if frameworks are used mechanistically or
uncritically, they can hinder a deeper, questioning
analysis, that remains open, for instance, to factors
that do not feature in the framework [“other means
than ES”] (Fisher et al., 2014: 35).

“Forest resources [and their derived ES] may contribute to
local livelihoods through:
(1) a needs-driven forest reliance, whereby local poor
people depend on low-value forest resources to some
extent for their livelihoods, perhaps in response to
shocks (“safety nets”), or
(2) because they are unable to make the transition out of
this resource dependent mode (“poverty traps”); and
(3) an opportunity driven forest reliance, whereby local
people use higher-value forest resources as a source
of cash products in order to get richer (“pathways out
of poverty)”(Clements et al (2014: 125-126)

know?

Impact evaluation methods utilised to investigate the effect of protected
areas (PAs) on poverty and livelihoods in Cambodia (comparing
households inside PAs with bordering villages and controls) found that:
There was no evidence that PAs exacerbated local poverty or
reduce agricultural harvests in comparison with controls
(Households bordering the PAs were significantly better off, not
because of the PA but due to greater access to markets and
services).
Non-timber forest product collectors inside PAs were significantly
better off than controls and had greater rice harvests, because they
had more secure access to land and forest resources.
The PAs in Cambodia therefore have some positive impacts on
households that use forest and land resources for their livelihoods
(Clements et al (2014: 125)

Development as
1. welfare,
2. utility or
3. freedom maximisation (and equalisation)
All concepts still in use, dependent on
• Academic discipline,
• Underlying assumptions, e.g. regarding the welfare models
(growth-mediated vs. support-led strategies),
• Practical concerns (used in structural equation models,
linear correlation analysis, qualitative evaluations, impact
assessments, etc).
Dependent variable “Well-being”: Equality of what (Sen, 1980)?
8Source: Sen, A. (1980), “Equality of What?”, in McMurrin, S. (ed.): Tanner Lectures on Human Values, Cambridge, Cambridge University Press
Money-metric poverty assessments:
• Identification a) per adult equivalent consumption as the
welfare metric,
• Identification b): an absolute poverty line, usually based on
the Cost of Basic Needs Method
• Aggregation: Use of FGT method (1984) - FGT0 (poverty
headcount (incidence of poverty), FGT1 (poverty gap –
incidence, intensity and depth of poverty) or FGT2
(squared poverty gap - incidence, intensity, depth of
poverty and inequality among the poor).

Each computation of poverty is imperfect and can be critiqued from different angles.
Substance:
• Caloric intake not suitable to assess nutritional quality of diet
• Each person converts means (income) differently to ends (human development,
e.g. a healthy diet)
• Non-deprived in income does not mean access to health care is ensured
Utility:
• “Empirically, MPI poverty much less varied spatially than income poverty” (Gaddis
and Klasen, 2012) – do you want to see spatial differences?! Do you want to see
abrupt/non-linear changes?

• The household does not have all-year long access to clean drinking water
(according to the MDG guidelines) or clean water is more than 30 minutes walking

health specialists
• No household member is able to read and write; no household member achieved
EP1 or attended the Portuguese colonial school system.

• Household did experience a food shortage in the past
• The household did not receive advice from an extension agent during the last 12
months, and did not receive a credit in the last 12 months, and is currently not a
member in either an agricultural or forestry association.

Poverty Index
Challenges:
1. Explicit value judgments: as cardinal data is mixed with ordinal
and categorical data, value judgments to set poverty lines are
required
2. What constitutes “adequate housing”, “access to health care”,
“food security” is often multidimensional itself and thus hard to
capture by a single indicator or a proxy
3. Ideally, variables do not correlate much – challenges to link ES
or EG to well-being (e.g. sanitation, clean water access)
4. “Change” analysis: Panel data often not available, necessitates
alternatives (space-for-time substitution). Practical challenges
occur - controlling for similar soils and woodland vegetation and
a similar provision of public services within study sites is, in
reality, a much harder task than on paper
15
Use of multiple dependent variables in
regression
Studies increasingly use multiple dependent variables in regression
analysis
• Hossain et al. (2015) used linear regression, among other statistical
techniques, to analyse how ecosystem services are coupled to economic
growth and well-being in the in the Bangladesh coastal zone (Well-being
defined as poverty (% of population below poverty line), Per capita
income, Gross domestic product)).
• Santos et al (2013), in “Ecosystem and Human Wellbeing in Spain”,
used structural equation modelling to explore "the relationships between
biodiversity loss, ecosystem services, human wellbeing, drivers of
change (both direct and indirect) and policy responses” (10 well-being
indicators)

Enhancements of our understanding, some observations…
• Preference for cardinal indicators (less room for different interpretation of
results/easier to show trends (linearity)/ use of quintiles rather than a poverty line
– while it adds knowledge to the picture, it does not capture the entire picture)
Access to services or markets = distance (physical accessibility to services),
but says little about their financial affordability, social acceptability, quality of
services
• Covariates: “Poor matching designs might identify an effect when in fact none
exists or mask effects […]. A simple comparison of households inside the PAs with
bordering villages would come to the conclusion that PAs exacerbate local
poverty. The results of the impact evaluation show that this would be a misleading
comparison, because border villages were closer to market centers, other
services, and main roads, all of which had positive impacts on local poverty
status” (Clements et al (2014), S129 – S130)
Finding the right control variables might be challenging if the dependent
variable is a composite index with various types of variables, links to different
dimensions of well-being, and variables that link either to public or private
goods (Keyword: Endogeneity)
“Soft variables" (social dynamics, exclusion, etc) are harder to use
Use of multiple dependent variables in regression
17
The way forward: Use of Poverty Index in regression
1. Micro regression (determinants of poverty of a person or household)
2. Macro regression (determinants of poverty at the district, state, province
or country level, ethnic group, gradient level)
Endogeneity is a great challenge with multidimensional poverty/well-
being: high correlation between a variable constituting the dependent
variable with an independent variable (the same forces that influence the
input also influence the output – ownership of goods (motorcycle) to
explore forest resources). Alternatives:
• Instrumental variable (exogenous variable thought to have no direct
association with the outcome (harder to find with multidimensional
poverty composed of indicators that are not highly correlated)
• Nonindicator measurement variables, e.g. certain demographic
characteristics or additional socioeconomic characteristics of the
household (ethnicity, hh size, etc.) (possibly not very satisfying)
Well-being determinants might change across spatial differencesSource: Alkire et al (2015), “Multidimensional Poverty Measurement and Analysis: Chapter 10 – Some Regression Models for AF Measures”, in Alkire, S. et al.
