“…Second, sugar cane crops can be used for phytoremediation 23 of the soil. Empirical evidence by Wang et al (2017b) shows that heavy metal soil concentration declines with sugarcane phytoremediation as compared to areas without sugarcane treatment.…”

Clean water has a largely unknown economic value, particularly to small communities whose agricultural activities take place on river shores. In November 2015, the rupture of a mining tailings dam in the municipality of Mariana led to a record disposal of toxic residuals in southeast Brazil. A mud avalanche ran out for 600 km (373 miles) until it reached the Atlantic Ocean, leaving behind extreme ecological and economic damage in the Doce River basin. This is the largest environmental disaster in Brazil to date. We quantify the negative externalities using rich, identified, and comprehensive data from firm-to-firm electronic payments and individual-level consumer credit usage. We find that agricultural producers in affected municipalities received cumulatively 41% to 60% fewer inflows (income) from customer firms outside the affected zone three years after the disaster. Effects are driven by municipalities where the river shore is larger relative to the farming area. In these municipalities, individuals also faced an 8% fall in their credit card and consumer finance expenditures. This result is stronger for non-formal and high-risk workers. Thus, water contamination led to (first) production and (later) consumption decline with real effects on municipality-level agriculture and services output, causing a 7% decline in local GDP.

“…The densely 300-width and 9000mlength cane belt covered alongside the south of island has reduced the flood risk over the last decades according to the report published by National Organization of Environmental Conservation (2010). Moreover, as studies have suggested the use of canes for water and soil filtration due to their phytoremediation character (Wang et al, 2017), they are used for reducing farmlands' contamination in south of the island. The sugarcanes are also a source of sugar provision.…”

The number of shrinking cities is rapidly growing and posing new planning and design challenges worldwide. In this regard, understanding urban decline from an integrated ecosystem services/disservices perspective is limited in the literature and is considered as a critical basis for revitalization programs. Minoo Island as one of the emerging shrinking cases in Middle East has considerable characteristics in terms of both positive and negative aspects of ecosystem in population decline. This paper aims to investigate various ecosystem factors resulting in urban shrinkage in Minoo Island as a consequence of the Iran-Iraq war in 1980s. The research method of this study is based on qualitative assessment of ecosystem services/disservices by using participant observation and semi-structured interviews. An integrated ecosystem services/disservice analysis was applied for assessment of ecological functions and assets. The results of this paper show that despite remarkable ecosystem potentials and functionalities in Minoo Island, it suffers from detrimental effects of ecosystem disservices leading to population decline over the past decades. Finally, this paper proposed some green-oriented design and planning strategies such as ecological protection, river restoration and green infrastructures for revitalizing Minoo Island.
