Data Basin: A Mapping Tool for All

Data Basin, an online system, is quickly growing in popularity among practicing educators and community groups that wish to tell compelling stories with graphics. Data Basin connects users with spatial datasets, tools, and expertise through a user-friendly platform where “individuals and organizations can explore and download a vast library of datasets, upload their own data, create and publish analysis, utilize working groups, and produce customized maps that can be easily shared.”

In a presentation on its potential, Jame Strittholt, Data Basin’s founder and Conservation Biology Institute‘s Executive Director called it Google Earth on steroids meets Facebook, allowing groups to communicate with each other by integrating conservation data, mapping, and people. The site contains groups for specific topics and issues and centers for targeted geographies. The core functions of Data Basin are free and a fee-based consulting service is available for those who wish to take full advantage of its features or store significant amounts of data. Currently a great variety of biological, physical, and socioeconomic data is available. Maps can be kept private, within groups, or open to the public.

Data Basin was created out of the need for a central access point for environmental conservation related datasets that people can explore. The tools are easy to understand and use, making it an excellent resource for nonprofessionals or those unfamiliar with ArcGIS. Data Basin was implemented by the Conservation Biology Institute in partnership with ESRI.

Combating Climate Change in Nepal

How can mobile phones address issues raised by a changing climate? A study by Shrandha Giri and Yuwan Malakar of the University of Manchester with support of the International Development Research Centre (IDRC) looks at a successful campaign in Nepal that takes advantage of the widespread usage of mobile phones.

Greater variation in precipitation, higher average temperatures, and a fragile geography prone to flooding have been noted by Nepalese farmers as signs of climate change. In light of these concerns, a phone-based early warning system was created to exchange information on flood signs and other occurrences among communities. The system also provides a list of service providers and traders in the agricultural field. The study notes three critical ways in which mobile phones benefit these farmers:

1. Agricultural Practices: alongside the typical problems of low-productivity agricultural practices and poor access to inputs, farmers in the villages are also reporting with a presumed link to climate change the arrival of new pests and diseases about which they have limited knowledge. This has affected the level of outputs because of the novelty of these challenges and the lack of availability of local agricultural technicians. The project provides the farmers with the phone contacts of technical service providers, which they have then used to get advice about treating crops and livestock. They also use this service for more general advice on seed varieties, planting times and methods with the aim of raising incomes and thus reducing vulnerabilities.

2. Market Prices: in order to reach the nearest market, farmers in Kirtipur have to walk 10km along a train route and then travel a further 5km by bus. Because of the higher costs of reaching other markets and complete uncertainty about prices in those markets, farmers would always sell in the nearest market at whatever price the local traders would offer. With climate change and flooding potentially suppressing the level of outputs they could achieve, this was a severe threat to income levels. The project therefore also provided the farmers with a phone contact list of agricultural traders in a number of nearby markets. As a result, not only are they better informed about reasonable market price levels for their outputs, they can also compare prices between traders and justify journeys to whichever trader is offering them the best price.

3. Disaster Early Warning: Flooding, particularly the recent growth in occurrences and severity which is assumed to be linked to climate change, causes problems to the farmers in loss of crops and livestock, inability to access markets when there are landslides, and more general dangers to life and property. The project provided a phone list of key contacts in both upstream and downstream communities. When there is continuous heavy rain, those in the upstream areas phone and warn those in the downstream communities, who are then able to prepare and evacuate livestock, property, family, etc. They also warn about landslides that may block planned transport routes. In return, those in the downstream, more populated, better connected and more commercial areas, provide information on markets, agricultural practice and development opportunities.

The information needed to create this network was provided through a participatory vulnerability assessment (PVA) conducted by Practical Action, village development committees, and agricultural groups affiliated with government district offices. In this survey farmers noted the changing dry season, erratic rainfall, and movement of farmers due to a lack of irrigation. The project is deemed successful because it involved local people’s motivations such as financial gain. The use of ICTs reduces vulnerabilities and makes communities more resistant and perhaps productive by mitigating long-term changes in the local climate.

Cheat Sheet: ICTs for Climate Change

How can ICTs be used to combat climate change? Stan Karanasios’s paper entitled “New & Emergent ICTs and Climate Change in Developing Countries” outlines emerging ICTs in 3 steps:

monitoring of climate change and the environment
disaster management
climate change adaptation

Excerpts from the paper outline uses of ICTs for climate change:

Monitoring of climate change and the environment

For developing countries to better understand their local climate and be able to anticipate climate change impacts, they must have adequate local and national observation networks, and access to the data captured from other global and regional networks.

Types of technology include:

satellite systems
wireless broadband technologies
wireless sensor networks (WSN)
mobile phones
hand-held devices

Examples of environmental monitors:

Rainfall and Landslide- In hilly regions of western India, SenSlide, a distributed sensor system, predicts rather than just detects landslides. Landslides occur frequently, often during the monsoon when rain causes significant damage. SenSlide makes use of WSN and strain gauges, providing data to a network.
Fire- In South Africa, FireHawk, a forest fire system of cameras with zoom lenses and microwave transmitters and receivers was implemented in mountainous and extreme temperate locations. The system automatically detects fires, even at night, limiting the impact of damage.
Flood- In Honduras, a WSN for flood monitoring was developed that was able to withstand river flooding and the severe stromes causing the floods, communicate over a 10,000 km river basin, predict flooding autonomously, and limit cost, allowing feasible implementation of the system.
Impacts of Agriculture- In India a WSN-based agriculture management system named COMMON-Sense Net, was deployed to support rain-fed agriculture and provide farmers with environmental data. Wireless sensors were deployed in geographical clusters, each with one base-station that was connected to a local server via a Wi-Fi link and organized in groups, each corresponding to a particular application, such as crop modeling, water conservation measures, or deficit irrigation management.

Disaster management

Responding to natural disasters in a timely and effective manner has emerged as an important climate change theme particularly in developing countries; where in addition to the immediate crisis vulnerable communities suffer excessively from the secondary post-disaster effects that compound the tragedy. In many cases, the existing telecommunication infrastructure will be significantly or completely destroyed by an extreme weather event, and hence rapidly deployable networks and other communication services need to be employed for disaster relief operations.

Communication Methods:

Emergency Communication Systems- In Bangladesh an Integrated Information and Communication System is underway which will use satellite, wireless broadband, mobile phones and community radio services strengthening communication links between rescue and relief units and Emergency Operation Centers (EOC).
Rapidly Deployable Communications
Social Networking- During Typhoon Ondoy in the Philippines in 2009, local volunteers organized and disseminated information online through websites such as Facebook and Twitter. Organizations and affected people used these sites for timely reports concerning the extent of damage, to provide information on the resources required tand to allocate relief resources.
GIS & Other Information Systems- Visualize high risk zones; evacuation routes, shelters and the catalogue of available resource and their proximity
Early Warning Systems- satellite radio, mobile phones, cell broadcasting system, the web, WSNs, and CAP (common alerting protocol) can be coupled with climate data for immediate and short/medium/long-term warnings to minimize harm to vulnerable communities.

Disaster Management Project Example: Project DUMBO

Mesh Networks and Disaster Response in Thailand DUMBO, a project initiated by the Asian Institute of Technology Internet Education and Research Laboratory, developed and tested asystem for response to emergency scenarios in Thailand . Making use of the concept of wireless mesh networks, DUMBO uses lightweight portable mobile nodes to broaden coverage and penetrate deep into areas not accessible by roads or where the telecommunication infrastructure has been destroyed. During the trials in Thailand, laptops were carried on elephants to extend thewireless mesh network coverage. On the networking side, the solution utilised hybrid WiFi and satellite connectivity. The second application component involved sensors, which allowed for readings of environmental data such as temperature, humidity, pressure, windspeed, wind direction, rainfall and CO2. The third application component involved facial recognition software that allowed rescuers to compare facial images captured from the site to the collection of known faces. This is one of a few systems in developing countries that make use of emergent technologies and combine communications with integrated disaster applications

Climate change adaptation

To cope with current and future climate stress, communities – particularly those most vulnerable to developing countries – must build their resilience, including adopting appropriate technologies, while making the most of traditional knowledge, and diversifying their livelihoods. For instance, monitoring networks can inform habitat location (provide information to house communities away from a flood or landslide in prone areas), better agriculture (based on informed climate information or water allocation) and provide early warnings, amongst other applications. Mobile technology should be scaled-up for adaptation.

There is a lot of room for growth in developing ICTs for adapting to climate change through collecting, analyzing and disseminating information particularly in space-based systems, GIS, WSNs, wireless broadband technology, mobile technology, and soft technologies such as Web-based tools. By doing so, bottom-up local coping strategies will be encouraged.

The Amazon as Never Seen Before

Last week The Guardian announced that we’re now able to see the Amazonian rainforest as never seen before. A group of scientists, using LIDAR (Light Detection and Ranging) took images from a plane called the Carnegie Airborne Observatory. The images were taken by bouncing a laser beam off of the forest canopy at 400,000 times per second. The resulting images are vibrant, showcasing variation in biodiversity at unprecedented detail. The new technology will be used to manage the ecosystem, monitoring for signs of deforestation and degradation.

Mexico’s Climate Challenge: ICTs pave environmental policy

Mexico’s bouquet of distinct ecosystems features an assorted variety of species, making the country one of the most biologically diverse in the world. The gem of Mexico’s ecological abundance is in great danger due to the forces of climate change. The country’s coastal regions risk destruction from tropical storms. Other problems include heavy rains that increase flash flooding and pollution that dulls overall health. Environmental deterioration and degradation can be traced as a root cause of current social and economic problems in Mexico, especially as poverty is agitated by the effects of climate change.

In June 2011 the Association of Progressive Communications (APC) released “ICTs and environmental sustainability: Mapping national policy-making and climate change strategies“. In the report, the authors note the potential for ICTs in Mexico but warn of the overall disconnect between policy-making and climate change strategies. A critical piece missing is the general lack of communication infrastructure. The report cites a study that states that Mexico has the second lowest broadband density of all countries in the OECD and in comparison to other countries Internet is slow and expensive. In 2010, only 30 out of 110 million Mexicans had access to Internet.

There is great potential for ICTs to litigate climate change in Mexico. The report points towards solutions for integrating ICT into the sector, noting the limited budget and lack of private investment in technology. Despite this, in 2010 Ericsson declared that they supported launching a public-private partnership for low-carbon solutions at the Conference of Parties to the United Nations Framework Convention on Climate Change held in Cancun (COP16).

Some proposed areas where ICTs can be introduced include:

tracking carbon footprints and using sensors to improve energy use efficiency
surveying water use
using geographic data for flood prevention
creating information dissemination and consultation systems to prevent and issue early warning in vulnerable situations such as natural disasters that can coordinate members of the National Civil Protection System
updating the national volcanological monitoring system
forming a surveillance system for land conservation

Biofuels: Off-grid answer for ICT access?

Biofuels… Good or Bad Idea? They’ve received positive hype from non-profits, corporations, and individuals only to be scorned by some environmentalists, economists, and other groups.

A common barrier facing rural regions is a lack of access to a reliable power supply. Being off the grid limits the ability to take advantage of information and communication technologies (ICTs) that could provide economic gain and increase quality of life. What’s the use of a mobile phone with innovative software applications if it can’t be recharged?

One popular answer for off-grid communities is building biofuel-based facilities that are run off of renewable resources. Biofuel is simply energy released directly or indirectly from living or recently living organisms. Wind and solar power are included, but fossil fuels are not because they are embedded in geological formations and nonrenewable.

Biofuels have been used for over a millennia, such as the simple method of burning wood for fuel. Other traditional methods used throughout the developing world include using conventional feed such as maize, wheat, sunflowers, and switchgrass for combustion that are then used for cooking, heating, and lighting.

Modern bioenergy used for fuel can be more complex, taking advantage of residue, bacteria, and other organic components of waste that produce a higher value energy carrier, meaning they are more efficient and versatile than traditional methods. The most common method for converting biomass into fuel is by combustion that generates heat. Other known methods include gasification, extraction, and fermentation (used for converting starch or sugar crops into ethanol). In recent decades ethanol and other forms of biofuels have increased in popularity due to the fluctuation of oil prices, carbon emission, and as an option for rural development.

So are biofuels the answer for connecting rural communities with the greater world? Let’s weigh some notable advantages and disadvantages:

PROS

+ Biofuels are locally harvested, decreasing transportation costs.

+ The harvesting and processing of biofuels creates local jobs.

+ Biofuels are renewable.

+ Plants used for making biofuels can be grown on marginal lands.

+ The cost of renewable energy technology is falling, making energy projects more affordable and easier to maintain.

CONS

– Not all biofuels are sustainable.

– Traditional forms of bioenergy can cause unpleasant consequences such as deforestation.

– Traditional biofuels are highly inefficient when compared to fossil fuels and nuclear energy.

– Biofuels derived from vegetation require a lot of water, adding pressure to an already limited and fragile source.

– Instead of using limited arable land for food production, it’s used for growing biomass that can be improperly fertilized, further harming water systems.

– It can negatively impact life-cycles, species health, and biodiversity.

So are biofuels a good or bad solution for rural areas? The decision must be made at the local level; weighing costs, benefits, and sustainability. Below are examples of successful projects where biofuels are used to supply power.

Indonesia– Instead of depositing livestock waste in waterways, it is processed in a biodigester, creating biogas used by the local population.

China – Rice ‘straw’, the stem and leaves left behind after harvesting to be burnt can be mixed with an alkaline solution to create biogas.

Mali– Jatropha, a poisonous weed used to keep away grazing animals thrives in marginal soil is used to power generators.

Kenya– Solar and hydro energy is used for a power center that provides access to Internet and mobile phones for local farmers.

Lionfish, Tiger Shrimp, Grizzlar Bears! Oh, my!

Photo Credit: Factoidz

Last summer an article caught my eye about the spread of Lionfish in Antigua’s waters, an invasive and predatory creature. The news made me curious if there were other invasive species worthy of catchphrases and surely enough I wasn’t disappointed to find a diverse selection of tigers and bears.

Invasive species, as the name suggests, originate outside of the ecosystem in which they are found. Thousands of years of climate shifts and our urge to conquer new lands have led to major disruptions that threaten native environments, making them susceptible to damaged local biodiversity, food production, and even human health.

In 2005, ICT Update published an issue on invasive species, marking GIS and other tech responses to the monitoring and elimination of threatening pests. Since this publication there have been successful ICT approaches and projects for invasive alien prevention. What’s my favorite one, you may ask? Well, it’s actually a free, simple to use mobile application called What’s Invasive! With this downloadable application one can geo-tag invasive plants and animals that are specific to the desired geographic location. With this information concerned citizens and other groups can monitor growth patterns and participate in eradication campaigns. Currently, the application is vigorously used in American, Canadian, and European parks. With its easily accessible databases, nature education and other public outreach programs in coordination with this mobile app can greatly empower local communities to address issues of environmental protection and climate change.

5 ICT 4 Watershed Management Projects

There’s been considerable debate lately about possible uses of information and communications technology for watershed management. Access to monitoring programs assists governments adequately manage and distribute water. Watershed management is critical for regional ecological health, clean water ability, disaster relief, and agriculture.

5 Noteworthy ICT Watershed Management Projects

eGov features India’s Mahatma Gandhi National Rural Employment Guarantee Scheme (MGNREGS) that uses GIS mapping and GPS enabled mobile applications for planning and monitoring rainwater harvested agricultural land. The watershed is analyzed through interactive online mapping available in local languages, engaging parties at the village, regional, and state levels. Through this process scarce water is conserved by a supervised drainage line, promoting the cultivation of arable land and responsible seasonal planning. An overview of this project is available HERE.

A similar project, MeKongInfo, is available to citizens along the Mekong River Basin in Cambodia, Thailand, Laos, and Vietnam. The site houses a database and online discussion that is sponsored by the Mekong River Commission (MRC). It contains many aspects including flood mitigation, fishery management and other issues of overall planning.

AgWater Solutions is collaborating with the International Water Management Institute (IWMI) and others in Ethiopia through workshops to address small reservoirs and groundwater systems investment.

African Water Facility’s Community Water Management Project in Zambia works with farmers to increase productivity by reducing their reliance on rain-fed farming.

Rio+20’s ICT as an Enabler for Smart Water Management report includes case-studies on ICTs for smart water initiatives. Also worthy of noting as a resource is the United Nations’ Virtual Learning Centre distance-learning course on Integrated Water and Environmental Management for creating regional resource databanks to enhance sustainable water management practices. The course is available through Regional Centres of Excellence in Africa, Asia, and the South Pacific.
