Abstract: The composition of termite assemblages was analyzed in three caatinga sites of the Estação Ecológica do Seridó, located in the municipality of Serra Negra do Norte, in the state of Rio Grande do Norte, Brazil. These sites have been subjected to selective logging, and cleared for pasture and farming. A standardized s ling protocol for termite assemblages (30h erson/site) was conducted between September 2007 and February 2009. At each site we measured environmental variables, such as soil pH and organic matter, necromass stock, vegetation height, stem diameter at ankle height (DAH) and the largest and the smallest crown width. Ten species of termites, belonging to eight genera and three families, were found at the three experimental sites. Four feeding groups were s led: wood-feeders, soil-feeders, wood-soil interface feeders and leaf-feeders. The wood-feeders were dominant in number of species and number of encounters at all sites. In general, the sites were not significantly different in relation to the environmental variables measured. The same pattern was observed for termite assemblages, where no significant differences in species richness, relative abundance and taxonomic and functional composition were observed between the three sites. The agreement between composition of assemblages and environmental variables reinforces the potential of termites as biological indicators of habitat quality.

Abstract: The rapid increase in cooling demand for air-conditioning worldwide brings the need for more efficient cooling solutions based on renewable energy. Seawater air-conditioning (SWAC) can provide base-load cooling services in coastal areas utilizing deep cold seawater. This technology is suggested for inter-tropical regions where demand for cooling is high throughout the year, and it has been implemented in islands with short distances from the coast and the deep sea. This paper proposes adjustments to the conventional design of SWAC plants to reduce implementation risks and costs. The approach is named high velocity SWAC and consists of increasing the excavation depth of the seawater pump station up to 20 m below the sea level, compared to 2 to 5 m in conventional SWAC projects. This allows a twofold increase in the speed of inlet pipeline seawater and cooling load of the plant. The cooling load can be expanded twofold with only 55% capital cost and 83% project costs, compared with the costs of a new system. In addition, this article shows that high velocity SWAC plants with thermal energy storage will have an important role supporting the dissemination of intermittent renewable sources of energy in regions where SWAC is a viable cooling alternative.

Abstract: Green roofs affect the urban food-water-energy nexus and have the potential to contribute to sustainability. Here we developed a generalizable methodology and framework for data-sparse cities to analyze the food-water-energy nexus of green roofs. Our framework integrates the environmental costs and benefits of green roofs with food-water-energy systems and makes it possible to trace energy-water-carbon footprints across city boundaries. Testing the framework in São José dos C os (SJC), Brazil and Johannesburg, South Africa, we found that green roofs are essentially carbon neutral and net energy consumers from a life cycle perspective. SJC is a net water beneficiary while Johannesburg is a net water consumer. Rainwater utilization could save irrigated water, but requires 1.2 times more energy consumption. Our results show that SJC and Johannesburg could direct their green roof development from local food production and energy saving, respectively and highlight opportunities for green roof practices in cities.

Abstract: Green roofs have gained relevance in urban sustainability and affect the urban food-water-energy nexus in cities in many different ways. However, it remains unknown regarding systemically quantifying the trade-offs of green roofs on urban food-water-energy nexus. Most city-scale research is restricted to a silo lens (e.g., life cycle impacts and food-water-energy related benefits) while research focusing on green roof’s multiple trade-offs occurs at smaller scales (e.g., neighborhood). Here we developed a generalizable integrated methodology framework for data-sparse cities to analyze the food-water-energy nexus of green roofs from an urban system perspective and tested the framework in two global south cities, São José dos C os, Brazil and Johannesburg, South Africa. We find São José dos C os could reach its total self-sufficiency of vegetables in prospect by green roof farming, whereas its life cycle energy consumption would achieve 45% of urban energy demand in the worst scenario. Fueled by the scheme of rainwater substitution, 96% of the life cycle water consumption in São José dos C os rushed to the infrastructure stage from the operation stage. Johannesburg had potential to satisfy 73% of urban vegetable self-sufficiency and contribute 8% to the city’s alternative water supply goal by rainwater harvesting. Local food supplies are cardinal drivers of trans-boundary water footprints beyond the cities of both São José dos C os and Johannesburg. We highlight the necessity to balance the trade-offs of green roofs orienting urban food-water-energy goals and call for opportunities for green roof practice in cities.
