Summary Background Unprecedented levels of habitat transformation and rapid urbanisation are changing the way individuals interrelate with the natural environment in developing countries with high economic disparities. Although the potential benefit of green environments for mental health has been recognised, population-level evidence to this effect is scarce. We investigated the effect of green living environment in potentially countering incident depression in a nationally representative survey in South Africa. Methods We used panel data from the South African National Income Dynamics Study (SA-NIDS). Our study used SA-NIDS data from three waves: wave 1 (2008), wave 2 (2010), and wave 3 (2012). Households were sampled on the basis of a stratified two-stage cluster design. In the first stage, 400 primary sampling units were selected for inclusion. In the second stage, two clusters of 12 dwelling units each were drawn from within each primary sampling unit (or 24 dwelling units per unit). Household and individual adult questionnaires were administered to participants. The main outcome, incident depression (ie, incident cohort of 11 156 study participants without significant depression symptoms at their first entry into SA-NIDS), was assessed in the adult survey via a ten item version of the Center for Epidemiologic Studies Depression Scale; a total score of ten or higher was used as a cutoff to indicate significant depressive symptoms. Each participant was assigned a value for green living space via a satellite-derived normalised difference vegetation index (NDVI) based on the GPS coordinates of their household location. Findings Overall, we found uneven benefit of NDVI on incident depression among our study participants. Although the green living environment showed limited benefit across the study population as a whole, our final analysis based on logistic regression models showed that higher NDVI was a predictor of lower incident depression among middle-income compared with low-income participants (adjusted odds ratio [aOR] 0·98, 0·97–0·99, p<0·0001), although when this analysis was broken down by race, its positive effect was particularly evident amongst African individuals. Living in rural areas was linked to lower odds of incident depression (aOR 0·71, 0·55–0·92, p=0·011) compared with study participants residing in urban informal areas that often lack formal planning. Interpretation Our results imply the importance of green environments for mental wellbeing in sub-Saharan African settings experiencing rapid urbanisation, economic and epidemiological transition, reaffirming the need to incorporate environmental services and benefits for sustainable socioeconomic development.

“…found that, open access nature of some resources and externality of market-oriented activities are the main causes of extinction and biodiversity losses (Berk;1979;Pearce and Turner, 1990;Pearce, 2007;Iritié, 2015). Bishop (1993) also pointed that, the extinction of living organisms such as fish is of economic concern because it may affect the sustainability of the resources and lead to economic losses imposed on future generations.…”

Lake Victoria fishery activities are of crucial economic importance to the communities around East Africa as they support the majority of fishers specifically through Nile perch fishing. As a consequence, increasing fishing pressure had also led to overfishing. This study employed the Data Envelopment Analysis (DEA) and Propensity Score Matching (PSM) techniques to assess the impact of Nile perch overfishing on technical efficiency of fishers based on a survey of 268 fishers across 10 landing sites in Lake Victoria, Tanzania. Results from the DEA show that, overall Nile perch fishers have average technical efficiency of 30% which indicates a high level of inefficiency. Specifically, there is no statistically significant difference in the technical efficiencies for Nile perch fishers who are overfishing and those who are not overfishing due to fisher’s mobility across the Lake. In addition, mode of propulsion and being a member of fishery organization were found to be statistically significant factors influencing inefficiency of Nile perch fishers. Furthermore, results from the probit estimates of the PSM show that being a member of fishery organization, quantity of Nile perch harvested per trip, age of a fishing vessel (boat), the gillnet mesh size and cost of fishing inputs have statistically significant effect in influencing the probability of Nile perch overfishing. However, further result indicates that Nile perch overfishing do not have statistically significant impact on fisher’s technical efficiency. Therefore, this study recommends a need to monitor and formalize fisher’s mobility as one of the alternative for co-management of the Lake. Also, overfishing can be controlled without necessarily affecting technical efficiency of Nile perch fishers through training and access to proper fishing gears.

“…This already occurs in some jurisidctions, such as France, where the development of biodiversity offsets requires negotiation with relevant stakeholders to ensure their interests are considered (Guillet & Semal, 2018). Stakeholder input and/or community consultation is needed to ensure that issues around conservation activities are resolved (Iritie, 2015;Rohr et al, 2018;Taherzadeh & Howley, 2016). Milestones also may need to include aspect of disturbance, as some species will only recruit to disturbed or structurally modified ecosystems (Tierney et al, 2017).…”

“…anthropogenic pressures, such as fishing), or areas where risk is too high/costs are too great for compensation. While the use of biodiversity offsets markets can be used to fill gaps in conservation priorities (Iritie, 2015), this can also be achieved by ensuring that offsets are linked to planning frameworks. Ultimately, if used in combination, greater cost and risk efficiencies may be achieved.…”

The interpretation and use of biodiversity offsets in planning and development is a contentious issue because they rarely encompass each of the environmental, social and economic aspects of sustainable development. While currently agreed best practice for biodiversity offsets includes consideration of scope, scale, location, timing and duration, and monitoring, current literature on these components does not consider all aspects of sustainable development. Furthermore, much of the current agreed best practice focusses on the design of biodiversity offsets, without consideration of ongoing management or end-of-life. This manuscript reviews current best practice for biodiversity offsets, giving consideration to the environmental, social and economic aspects of sustainable development. In particular, we report that consideration of cost and risk is key and the use of planning frameworks, bonds and advanced offsets could mitigate these risks and allow for long-term success. Following this approach, a holistic model for design, implementation and ongoing management of direct biodiversity offsets that balances all aspects of sustainable development is presented.
