Type of study:
Mechanism by which biodiversity affects poverty:
Biodiversity component details:
Aquaculture fish species.
Harvesting of fish effects the subjective well-being of the farmers involved, through cash generation and through job satisfaction.
Intervention employed other:
A project investigating the factors responsible for satisfaction and well being.
Measure of poverty impact used:
Subjective well-being and income (minor focus on income).
Assessment of impact on poverty:
Evidence assesses the scale of impact:
Sustainability of biodiversity use:
Attribute of biodiversity affecting poverty:
Does the evidence relate to a specific intervention?:
How does the mechanism affect poverty?:
It generates income/tradeable surplus
Mechanism affects poverty precisely how:
Cash generation influences subjective well being through the ability to purchase items to make their lives easier and more comfortable. Job satisfaction was also found to influence the subjective feeling of well-being experienced by farmers.
Evidence provides measure of poverty impact:
Evidence is site-specific:
Research method details:
Licket scales used within questionnaires and interviews.
Unit of analysis and sample size:
Does the evidence mention the general biodiversity status of the country/region?:
Does the evidence describe the biodiversity status of the site?:
Does the evidence mention the general poverty status of the country/region?:
Site poverty status described:
Does the evidence discuss the governance regime at the site?:
Does the evidence describe the poverty/socioeconomic status of the site?:
What is the resource rights regime?:
Resource rights regime details:
What is the land tenure regime?:
Land tenure regime details:
Privately owned and managed.
Does the evidence mention the power relations?:
Does the evidence consider possible trade-offs/costs as well as benefits?:
Costs and benefits details:
Detailed analysis into the costs of fish yields from aquaculture as well as a thorough look into the interacting variables.
Measure of poverty impact tag:
Distribution impacts considered:
Yes Detail on Specifics Provided
Duration of impact considered:
Distribution impacts details:
Age and education are examined and differing effects of increasing fish catch are found on different age groups and education groups are found. Age was found to have a positive effect on the probability of improvement in life quality of farmers. The regression results show that for older farmers, higher relative income from fish farming seems to lower their happiness levels. Although the coefficient of education is insignificant in the regressed model, the interaction between education level and job satisfaction is significant, suggesting that better educated farmers who are more satisfied with their fish culture would be slightly happier relative to those with lower education and satisfaction levels
Outcome replicable elsewhere considered:
Thresholds/boundary limits/tipping points of achieving the outcome considered:
How costs and benefits/impacts might vary across different spatial scales considered:
Presence of possible confounding factors acknowledged:
Yes acknowledged and taken into account in study design
Confounding factors details:
A number of variables are identified at the start of the paper and are tested for significance in the regression model, for example, age, education, income.
How mechanism affects poverty other:
Through job satisfaction subjective well-being is effected.
