Zika, dengue transmission expected to rise with climate change
- A new study foresees a 20% increase in cases of viruses like dengue, Zika and chikungunya over the next 30 years due to climate change.
- Higher temperatures are already causing the diseases carried by the Aedes aegypti mosquito to spread in cooler regions like southern Brazil and southern Europe.
- Deforestation also favors the spread of these illnesses because biodiversity-rich forests with more predators tend to inhibit mosquito populations.
- Brazil set a historic record in 2022, when more than 1,000 deaths resulting from the dengue virus were reported.

‘No place to hide’ for illegal fishing fleets as surveillance satellites prepare for lift-off
- A low-cost satellite revolution is paving the way for real-time monitoring of fishing vessels using synthetic-aperture radar (SAR).
- SAR allows researchers to monitor ‘dark vessels’ that aren’t transmitting Automatic Identification Signals (AIS) location data.
- Disabling or manipulating AIS transmitters is a tactic commonly used by vessels engaged in illegal fishing activity.

Conservation tech prize with invasive species focus announces finalists
- The Con X Tech Prize announced its second round will fund 20 finalists, selected from 150 applications, each with $3,500 to create their first prototypes of designs that use technology to address a conservation challenge.
- Seven of the 20 teams focused their designs on reducing impacts from invasive species, while the others addressed a range of conservation issues, from wildlife trafficking to acoustic monitoring to capturing freshwater plastic waste in locally-built bamboo traps.
- Conservation X Labs (CXL), which offers the prize, says the process provides winners with very early-stage funding, a rare commodity, and recognition of external approval, each of which has potential to motivate finalists and translate into further funding.
- Finalists can also compete for a grand prize of $20,000 and product support from CXL.

Reducing human-elephant encounters with calls, texts, and digital signs
- The Hassan district of Karnataka, India has been a hotbed of human-elephant encounters for years and a challenge for forest authorities, who have been translocating crop-raiding elephants for decades.
- Researchers have replicated an elephant alert system that combines signs, voice calls, and text messaging used in the elephant corridors of neighboring Tamil Nadu’s Valparai region to reduce negative interactions between people and elephants in Hassan.
- Using familiar technologies, the new system has reduced annual human fatalities in the region from several to nearly zero.

Top camera trapping stories of 2018
- Camera traps, remotely installed cameras triggered by motion or heat of a passing person or animal, have helped research projects document the occurrence of species, photograph cryptic and nocturnal animals, or describe a vertebrate community in a given area.
- Camera trapping studies are addressing new research and management questions, including document rare events, assess population dynamics, detect poachers, and involve rural landowners in monitoring.
- And with projects generating ever-larger image data sets, they are using volunteers and, more recently, artificial intelligence to analyse the information.

Peru’s Brazil nut harvesters learn to monitor forests with drones
- Brazil nut and ecotourism concessions in the Amazon maintain intact rainforest, but deforestation by illegal loggers, miners, and agriculturalists threaten the integrity of these lands and the Brazil nut industry.
- The Peruvian NGO Conservación Amazónica – ACCA is training concessionaires and forestry officials in southeastern Peru to fly drones and monitor the properties they manage using drone-based cameras.
- The resulting high-resolution aerial images enable concessionaires to detect and quantify deforestation within their Brazil nut, ecotourism, and other forest concessions and support their claims of illegal activity to the authorities.

Radar helps Kenya map mangroves and other cloud-covered forests
- Using Sentinel-1 radar imagery from the European Space Agency, the Forest2020 project has mapped a part of Kenya’s previously hard-to-assess coastal forests.
- The project’s findings show that 45 percent of the 83.5 square kilometers (32 square miles) of mangrove forest in a pilot county is highly degraded and in need of rehabilitation.
- These initial micro-scale maps of Kenya’s mangrove forests will help local forest officers and communities in areas with receding or recovering mangroves to take necessary coastal protection measures.

Satellite technology unites Kenyans against bush fires
- The Eastern and Southern Africa Fire Information System (ESAFIS), an online application developed in Kenya, uses MODIS satellite information to detect bush fires in eastern Africa.
- The freely available app maps and categorizes bush fires in near-real time and shows details of each fire , including the time it was detected, its location with respect to towns and protected areas, and its relative intensity.
- By providing an early fire warning system, the system helps forest management authorities respond to fires in their early stages and prioritize limited resources to fire hotspots.

Machine-learning app to fight invasive crop pest in Africa
- To monitor the invasive fall armyworm caterpillar in Africa, the UN’s Food and Agriculture Organization and Pennsylvania State University have collaborated on an AI add-on to FAO’s existing phone app to help farmers detect agricultural pests.
- The fall armyworm, an invasive pest of over 80 plant species, is native to the Americas but reached Africa in early 2016 and has wreaked havoc on their maize, threatening food security.
- The add-on, called Nuru, identifies leaf damage in photos taken by farmers and sends information to authorities to help monitor the presence of the pest.
- Detecting the pest quickly can help reduce unnecessary pesticide use that can damage human and ecosystem health.

Identifying Zika-transmitting mosquito fast, cheaply, and on the go
- A team at University of Texas Austin has developed a new method for identifying whether a mosquito is of the Aedes aegypti species, which is responsible for transmitting Zika, dengue and other deadly diseases.
- The method can easily be conducted while out in the field and does not need much more than a cell phone, a 3D-printed box and a few chemical solutions.
- This toolkit can also determine whether a mosquito has been exposed to the Wolbachia bacteria, which infects mosquitoes and prevents them from transmitting dangerous pathogens.
- Although portable tools and “biopesticides” such as Wolbachia are currently effective, adaptive dengue and Zika viruses will likely evolve past these tactics just as they have for countless other methods. Constant attention and funding is needed to stay ahead of such pathogens in this ever-lasting battle.

‘Better and better’: Thermal cameras turn up the heat on poachers
- The annual Serengeti-Maasai Mara wildebeest migration attracts not just tourists, but also bushmeat poachers, who kill between 40,000 and 100,000 animals along the way.
- In 2016, the Mara Conservancy began using FLIR thermal cameras, which detect heat instead of light, to find and capture poachers at night, when they are most active.
- Thermal imaging, together with a motivated team using high-quality digital radios, has led to the capture of over 100 people and left poachers at a loss as to how they’re being detected.

eDNA may offer an early warning signal for deadly frog pathogen
- Scientists sampling water for the environmental DNA of fish had the unique opportunity to test the potential of using eDNA to detect the presence of a fungus deadly to frogs while the animals are still healthy.
- The Batrachochytrium dendrobatidis (Bd, or chytrid) fungus has decimated frog populations across the world and is very difficult to detect until the frogs of a newly infected population start to die.
- The research suggests that eDNA could help managers predict which lakes and other water bodies harbor the chytrid fungus and take action to protect surviving amphibian populations.

Understanding bird behavior key to developing risk reduction technologies
- Billions of birds collide with man-made structures and aircraft every year, which devastates bird populations and harms companies that must pay the cost of damages.
- John Swaddle, professor of biology at the College of William & Mary, and his team have developed two technologies to help reduce the risk of collision, the Sonic Net and the Acoustic Lighthouse.
- The team applied an understanding of birds’ communication and migration behaviors to develop strategies that successfully reduce collision risk.

You don’t need a bigger boat: AI buoys safeguard swimmers and sharks
- A new tech-driven device may help reduce harmful interactions with sharks and improve people’s tolerance of one of the ocean’s top predators.
- The system, called Clever Buoy, combines sonar to detect a large object in the water, artificial intelligence to determine that the object is a shark close enough to threaten beachgoers, and automated SMS alerts to lifeguards that enable them to take action.
- Local governments have deployed the system at popular beaches and surfing sites to test its capacity to protect swimmers and surfers without harming marine wildlife.

Powering cameras and empowering people
- Keeping equipment running in harsh field conditions can challenge any tech project, as can working successfully with volunteers.
- Mongabay-Wildtech spoke with leaders of one project, wpsWatch, that deploys connected camera traps to monitor wildlife and people in reserves and employs volunteers to monitor image feeds from afar.
- Powering equipment for field surveillance and “making it part of everyone’s day” enable the rapid image detection, communication, and response by ground patrols needed to successfully apprehend wildlife poachers using cameras and other sensors.

Piloting PALM Risk to detect palm oil-driven deforestation
- The PALM Risk Tool, hosted on World Resources Institute (WRI)’s Global Forest Watch (GFW) Commodities platform, uses satellite imagery to show deforestation risk around 800 palm oil mills.
- Corporations can use the tool to increase transparency, improve plantation practices, honor sustainable palm oil commitments and preserve endangered species’ habitat; government and civil society can use it to hold companies accountable to stopping rampant deforestation for palm oil.
- Piloting the technology, Unilever found 29 high-risk mills in its supply chain, and it will work with unsustainable suppliers to improve their operations and curb forest loss.

Reducing human-wildlife conflict in the blink of a light
- As people settle closer to remaining natural areas, livestock predation by lions and other wild carnivores causes financial loss to often poor herders and farmers.
- Disruptive light systems, invented independently by herders trying reduce nighttime guarding of animals, emulate the movements of a night watchman to dissuade lions, foxes, and other predators from approach penned livestock.
- Users of Lion Lights, invented by 11-year-old Richard Turere, and similar light systems report very high success in deterring would-be predators and can play a role as part of a human-wildlife conflict reduction toolkit.

Light, long-lasting and low-cost: the technology needs of field conservationists and wildlife researchers
- The concurrent challenges of remoteness, extreme temperatures, dust, high rainfall and humidity, dense vegetation and steep terrain all complicate and limit the use of existing and emerging technologies for nature conservation and research.
- Survey responses of front-line conservationists suggest that no single technology will stop either wildlife poaching or human-wildlife conflict.
- Researchers everywhere desire smaller, lighter, longer-lasting, and more affordable devices that better withstand humidity, dust and damage.
- Integrated, automated devices and systems for detecting, monitoring, and providing early warning of movements of people and animals would revolutionize conservation and research work across species, ecosystems, and countries.
