Griffith University's new research found that ecotourism can save endangered species from extinction. Population viability modelling was used to quantify the impact of ecotourism on threatened species for the first time. Before then, net effect of ecotourism increasing or decreasing risk for endangered species, a crucial parameter for conservation efforts, could not be evaluated. Population viability models are widely employed in practical wildlife management to estimate cumulative population changes by simulating births and deaths thousands of time repeatedly, one generation at a time. Based on the models, scientists calculated future population alterations for 9 threatened species (orangutan, hoolock gibbon, golden lion tamarin, cheetah, African wild dog, New Zealand sealion, African penguin, great green macaw and Egyptian vulture).

All ecotourism effects whether positive or negative were transformed to ecological parameters. 7 species were found to have benefited from ecotourism factors (private reserves, habitat restoration, reduction in habitat damage, removal of feral predators, anti-poaching measures or captive breeding and food supplementation). The research also showed that net effects of tourism depends on species and sub-populations, which are influenced by local environment (scale and intensity of ecotourism, size of initial populations, rates of predation and impacts of other industries such as fishing, poaching and logging). Moreover, the research affirmed that ecotourism is not always successful as it can have net negative effect on threatened species in rare cases. However, for majority of endangered and rare bird and mammal species studied, ecotourism can help with their survival.

We are not printing so much nowadays as we rely on electrical versions and most paper is from managed forest. However, we still print, such as paper for editing is easier than looking through electronic screens and meeting handouts prevent distractions from electronic devices. Epson had developed PaperLab, “world’s first compact office papermaking system capable of producing new paper from securely shredded waste paper.” This will create a closed-loop recycling system in an office when its production start in Japan this year.

PaperLab's other advantage is decreasing energy consumption and confidentiality. It cuts out services and transport when recycling paper. Confidential papers even when shredded, no one is sure what happens once they leave the office, but PaperLab reprocess them immediately. The technology invented by Epson is quite simple. Waste paper is disintegrated into fibres without water with a treatment process called 'dry fibre technology.' When the fibres then bounded strongly enough, the user can add tint or fragrance or flame retardants for security and public safety, and choose paper thickness. However, it is unknown for number of times the process can repeat. Epson's innovation would be sustainability gem in an office if it is affordable and scalable.

Week 12-2 Smart Cities & State Policies


We all have changed the way we live, work and communicate as homes, businesses, cities continue to shift to newer and faster technologies. Internet-based advanced technologies are now the primary tool for cities and communities to gather, grow and share. There are currently 15 billion internet connected devices and the number is estimated to be 50 billion in 2020. To keep up with the demand, we need public policies that support transition from outdated networks to modern infrastructure,

A bill, AB 2395 has been passed in California to shift from outdated phone system to advanced IP-based technologies and services from 2020.  This will allow them to communicate effectively, quickly and intelligently to mitigate risk and conserve resources as urban population grows. Drought-plagued California's loses over 220 billion gallons of drinking water every year. The technologies can identify risks, and collect and analyse increasingly vast amounts of data to manage important resources better.

Old networks, which can no longer support cities' future needs avert investment and resources from modern infrastructure. Therefore, it is crucial for policy-makers to support modern network technology infrastructure for exceptional data and information sharing. IP-based technologies and services can improve quality of life and sustainability of the cities.

Week 12-1 Two-faced Solar Panels

Yingli bifacial panels

Solar energy becomes cheaper than ever as the market is more competitive so manufacturers lookout for new ways to differentiate their modules and make their products more efficient. To get more value out of solar panel, the sunlight reflected from the ground can also generate electricity. The bificial panels does exactly that aside from the usual sky-facing surface converting sunlight into power.

The firm Yingli China, one of the biggest solar module manufacturers in the world created bificial panels TwinMax series with their special technology known as Panda cells. They used 10% more efficient phosphorous instead of boron to treat silicon for conducting electricity. Panda cells gave more energy at the beginning and end of day.

As a result, TwinMax panels are 30% more productive than conventional modules. They also provide 30 year warranty, making them durable and reliable. This case shows that competition in sustainability technologies to make them work in better ways faster, and it is very exciting to look forward to the next better technology that will lead to a more sustainable future.

At present, companies need to reconsider their sustainability as the customers pay more attention to the topic, affecting their purchase decisions. Neilsen survey in 2015 revealed that brands that commit to sustainability grew more than 4% globally while those without grew less than 1%. Moreover, 66% respondents would pay more for sustainable goods, which is 11% increase from 2014.

Processes: Businesses can incorporate more sustainable practices in their business strategy such as reusing recycled parts in new products when manufacturing.

Products & Services: Businesses can create eco-friendly supplies and get certified by environmental bodies, such as Forest Stewardship Council to engage with customers.

People: Businesses can provide avenues for staff to participate in environmental initiatives, such as Earth Hour, nurturing them to give back to community.

Other than positive brand reputation, which can increase sales, sustainability initiatives can reduce operation costs. Sustainability initiative by companies are very effective because they also influence their partners, staff and customers. It is time for them, regardless of industry or size, to contribute more significantly for a sustainable future for upcoming generations.

Week 11-1 Eco Action Day 10 Years


Companies are hesitant to make more sustainable offices by switching to cleaner sources of energy or investing in energy efficient technologies due to economic or time constraints. Global Eco Action started in 10 years ago in Japan, encouraging employees, corporate partners and other organisations to reduce energy use. The Eco Action Day campaign was launched in Singapore a year later with 18 supporters such as a hospital, multinational corporations and a school.

Eco Action Day is now Singapore's oldest and longest campaign with more than 700 public and private sector organisations. The participants pledge sustainable actions such as switching lights off during lunchtime, and participants with especially ambitious and innovative pledges were rewarded. As a result, 200 tonnes of carbon emissions were avoided.

They believe "communicating environmental messages and conserving resources are the two cornerstones of sustainable environmental management." The government started to support Eco Action day by encouraging businesses, community and individuals to mange carbon footprint. They continue to expand globally and get everyone on board for a more sustainable living.

Week 10-2 Bleaching Great Barrier Reef

According to the recent findings, half of northern reef is dying because of coral breaching due to increase in temperature from global warming. Although scientists previously thought the waters would be too cool for bleaching, the worst breaching episode in Australia's history has occurred, and it would take several decades to recover from this damage. The coral reefs brought aquaculture and tourism, employing almost 70,000 Australians and produced higher than $5 billion for Australian economy every year.

However, the Australian government's budget for 2016-2017 reveals their continual support for polluting industries including coal and natural gas, rather than for reducing greenhouse gas emissions by cutting budget on renewable energy development. The Liberal's budget allocation missed out to lead globally with clean economy, providing jobs in public transport and clean energy to tackle global warming. It is is time to stop the polluters and protect essential services like clean energy, education and health.
