Capability, Suitability and Climate Programme for Wales

This three year project which is led by Welsh Government seeks to develop and improve the agricultural land classification model for the whole of Wales. It will assess the suitability of land for over one hundred different crops under 18 projected climate change scenarios. The project is being carried out by a consortium of Environment Systems, Cranfield University, and ADAS.

Initially Environment Systems will be focused on improving the accuracy of the underlying soil data. This will be achieved by modelling the regional distribution of certain soil series types which are known to be under – or over-graded in the Predictive ALC (Agricultural Land Classification) model. We will be analysing features such as pond density, rock outcrops and topographic setting to establish relationships with depth to impermeable clay, and total soil depth, and combining this with image analysis of vegetation characteristics, which will be tested with targeted soil sampling.

In a previous project for Welsh Government, Environment Systems assessed the suitability of areas for the planting of new potatoes. In this suitability modelling pilot, we modelled wind exposure, salt spray and frost pocket locations, and combined this information with a range of other biophysical information to demonstrate variations in land suitability for growing new potatoes. The current project will access additional Met Office data to produce more detailed wind exposure, salt spray and frost models, and apply these to the suitability modelling of over 100 crops.

By identifying the areas that provide suitable growing conditions for different crop varieties and highlighting crop suitability under future climate scenarios, the Welsh Government, farmers, public and private sector organisations will be able to make more informed decisions on the use of land. This will help farmers to think about the future and adapt to changing circumstances. It will give Government a greater understanding of the constraints and opportunities of our natural environment and help develop informed policy.

Three engagement events are being run in early 2019 to inform interested stakeholders about the project, one for the general public, one for Defra and associates and one for Natural Resources Wales and associates.

This project has received funding through the Welsh Government Rural Communities – Rural Development Programme 2014-2020, which is funded by the European Agricultural Fund for Rural Development and the Welsh Government.


 

From Imagery to Data

The insights that satellite data can deliver for agriculture are hugely valuable but making those insights accessible is not always straightforward for the people who might really benefit from them. We have recently demonstrated, as part of a national trial, the capability to deliver data insights in a simple data dashboard.

Intelligence dashboard
Stats can be presented in a simple business intelligence dashboard

In this example NDVI satellite imagery was supplied by Environment Systems Data Services. This 10m resolution product was used for each field for the 2017/18 season on a farm that produces winter wheat, canary seed, spring beans and and oil seed rape. This demonstrates both wide area coverage and the availability of weekly data from Environment Systems Data Services. 2017/18 season field statistics derived from both NDVI and radar satellite data were presented in a simplified business intelligence dashboard to demonstrate the capabilities for tracking and comparing field performance.

Near real time satellite data availability and analyses are now enabling growers to identify patterns and trends helping with both future planning of crop rotations and risk management.


 

Greenspace Accessibility

The West of England Nature Partnership (WENP) is working to enhance cultural ecosystem services in the West of England by ensuring that the value of accessible greenspace is implicit in decision making across spatial planning, public health and economic development. We were recently asked by WENP to establish current greenspace accessibility for the region. There is growing evidence of the physical and mental health benefits of green spaces. Research shows that access to greenspace is associated with better health outcomes, and that income-related inequality in health is less pronounced where people have access to greenspace.

Greenspace with catchments
Catchments (light green) show regions within 300m of green space (dark green) access points, calculated using the road network

On this project we took a range of existing greenspace datasets, some of which had known access points. Where the access points were not mapped, we produced modelled access points using the Ordnance Survey Integrated Transport Network (ITN). We also used the ITN to produce separate ‘walkable’ road networks for urban and rural areas, based on the road category, how busy the road is likely to be, and whether the road is likely to have a pavement. For example a busy B-road in an urban area might only be walkable if it had a pavement whereas a B-road in a rural area might be walkable simply because it carries much less traffic. We then ran a routing analysis to identify all of the areas falling within a 300m travel distance of a greenspace, producing catchment areas applicable to each. The result is spatial data that will enable WENP to carry out further analysis on greenspace accessibility and identify areas that currently have no, or poor access.


 

Landscape Monitoring in Dorset

Monitoring change is important for many reasons, and for those working in planning, development and environmental management it can be crucial in ensuring that the characteristics of an area are maintained or enhanced. Earlier this year Environment Systems was commissioned to undertake up-to-date analyses of the natural, built and historic environments, and to identify the different types of change that have taken place since 2007. The study focused on the Dorset area, specifically in the Dorset AONB and an extended area including parts of Hampshire, Wiltshire and Somerset.

The Dorset AONB
Dorset – rich in history with a varied landscape, featuring, broad elevated chalk downs, limestone ridges and spectacular coastal scenery

Initially our work focused on the natural environment. Detailed Phase 1 habitat data existed for part of the study area, but there were large gaps in coverage which we had to fill to create a seamless map. We achieved this using remote sensing image analysis of Sentinel-1/2 data and image segmentation using a classification rule-base to identify the basic land cover types. These includednarable, improved grassland, semi-improved grassland, heath, scrub, urban, water, wetland and woodland. In addition, we created habitat connectivity layers for the four key networks: heathland, grassland, woodland and wetland, via landscape permeability analysis.

The built environment presented a different set of challenges because the project required us to not only provide spatial data for the total urban extent in 2007 and 2017 with a range of comparisons but also for a number of features of interest including quarries, pylons, wind turbines, solar farms, caravan and camping sites, and car parks.

Additionally, we provided statistics and spatial data summarising areas that make up the historic environment. These included scheduled monuments, listed buildings, conservation areas, parks and gardens and designed landscapes. This was achieved using data from Historic England and Natural England.

Understanding how habitats have changed over time is important in an AONB especially from a planning perspective. We carried habitat change detection analysis by comparing the current habitat map against older data, and where no previous habitat data existed, through statistical analysis of satellite image data to identify changes in the reflectance characteristics over time.

Much of the data will be shared via DorsetExplorer, Dorset County Council’s publicly accessible mapping portal.

Team Building Day

Team Building DayOnce a year we down tools and staff assemble to take part in team building activities. This provides us with a chance to get to know each other better, work frantically and competitively in teams on some practical task that is both fun and challenging. Two years ago we set about litter picking on Aberystwyth beach, last year we built bug hotels. In October we travelled to some remote Forestry Commission woodland near Aberystwyth, and the site of a Scout activity centre. Having split into 4 teams we tackled, fire lighting, archery, rifle shooting, catapult building and tent erection. Despite rather dank weather a great day was had by all finished off by drinks and dinner back in Aberystwyth.

Drought and Flood Mitigation in Uganda

Agriculture is a major sector of Uganda’s economy accounting for the majority of the country’s exports and employment. This is partly due to Uganda’s warm tropical climate with plenty of rainfall and sunshine.

However, there are a number of threats to Uganda’s agriculture economy, which have implications for the ability of the country to meet the growing demand for food, compete in national and international markets, and increase productivity. These major threats include:

  • Climate change affecting the onset and length of the growing season, and increasing the frequency and severity of extreme events such as droughts and floods (Figure 1)
  • Biological risks (pests and disease) often exacerbated by climate change
  • Logistical and infrastructure risks, where farmers lack sufficient storage capacity and/or suitable road networks to get their crops to market
  • Market risks such as price fluctuations; a result of many influences including weather conditions
  • Political and security threats, for example cattle raiding, the influx of refugees and changes in land rights to name just a few
crop of beans in Karamoja, Uganda
A farmer tends to his crop of beans in Karamoja, Uganda, an area vulnerable to the effects of droughts.

The Drought and Flood Mitigation Service (DFMS) aims to help decision makers in Uganda address some of these threats. One way in which this is achieved is using Earth Observation (EO) data.

EO provides a means to assess and monitor agriculture from local to national scales. It is a powerful tool providing both current and historical spatial information on the environment, and is particularly valuable for rural and remote areas.

To demonstrate the power of EO for agriculture, Environment Systems has been working with Kakira Sugar (one of the major sugarcane growing companies in Uganda). Given that Uganda is one of the largest producers of sugar in East Africa, any data that informs on the state of the crop will enable sugar producers to make more informed decisions when growing sugarcane, safeguarding it’s production for national and international consumption.

Kakira Sugar Estate Uganda
Sugarcane growing on the Kakira estate

Sugarcane itself is a tall perennial grass that can grow two to six metres tall and requires a good supply of water. Typically, sugarcane is grown on a plantation surrounding a processing plant. Sugarcane can also be found in areas surrounding the plantation, grown by communities and individuals. These are known as outgrower farmers. This agriculture practice is seen at Kakira’s main estate.

Environment Systems are now engaging with Kakria in order to understand the agricultural practices that are employed (e.g. planting of different crop varieties, application of fertiliser etc.) and how such practices can be monitored from satellite imagery. Ultimately, we are helping Kakira to improve their decision making when it comes to planting, applying fertiliser or herbicide, irrigation and harvesting. Such insight will reduce their inputs, produce less waste and increase their yields.

Expo Agrofuturo

AGROFUTURO 2018In August we travelled as part of a delegation from the Department of International Trade to showcase British companies, on the British Embassy stand at Agrofuturo 2018 which took place in Bogotá, Colombia in August. This well-attended event focuses on the agriculture sector and is considered to be the leading business and knowledge event for the Agro industry in Latin America. On the stand we presented our Data Services products and SENCE natural capital solutions.

Our Senior EO & Business Consultant, Pascale Bodevin, featured in a promotional video (youtu. be/NMd3PRu16hk) for the event explaining how Environment Systems was using EO in the EO4cultivar project.


 

IGARSS 2018

International Geoscience and Remote Sensing Symposium (IGARSS 2018)The EO4cultivar project that Environment Systems is leading in Peru and Colombia provides for three fully funded PhD studentships in the UK. One of these, Christian Silva, presented a paper at the recent International Geoscience and Remote Sensing Symposium (IGARSS 2018), which took place in Valencia, Spain in July. Christian’s paper covered the use of Sentinel 1 ‘polarimetry’ (PolSAR) data and its role in improving the monitoring of agricultural fields, identification
of specific crop conditions, growth stage and change detection. Polarimetry deals with the way that radar ‘backscatter’ is related to geophysical properties on the ground.


 

Ecosystems in a Changing World

Ecosystem Service Partnership - Ecosystems in a Changing WorldKatie Medcalf, our Environment Director, together with Natural Resources Wales (NRW) will be presenting at the ESP (Ecosystem Services Partnership) Conference being held in San Sebastian, Spain in October (espconference.org/eu2018/). The Conference is organised under the theme: ‘Ecosystem services in a changing world: moving from theory to practice’. The conference is considering how ecosystems are essential to human wellbeing and will bring together practitioners to grow understanding of ecosystem functions and services to meet the demand from both policy makers
and practitioners for guidance on how to implement ecosystem services.

In the joint presentation ‘Mapping ecosystem services in Wales for health, well-being
and environmental resilience at a local to country scale’ we will focus on our work in the mapping and modelling of ecosystem services in Wales. Identifying areas with opportunities to enhance ecosystem services where there is a high demand. This data is a key information source to underpin the work of NRW to meet the Welsh Environment Act (2016). The talk will will conclude by demonstrating how the maps are being used in practice at a local level with communities and stakeholder groups.

Data Services Focus

There has been huge growth in the availability of satellite data in recent years. In most instances the data remains expensive and in the hands of the specialists. The Copernicus Sentinel program has opened up many opportunities to bring Earth Observation (EO) data into the mainstream. We have taken advantage of this open data source and for the past two and a half years made some of it available via Environment Systems Data Services. Our Data Services remove the hassle of managing and processing terabytes of data; users simply choose a product, an area of interest, a chosen point in time or time series and downloads the data in a ready-to-use format.

Sentinel 1 Composite Image - February 2018
UK – February 2018 – Sentinel-1 composite image – light blue colour is grassland and forests, dark blue less productive upland vegetation, orange denotes cropland and bright yellow, urban areas. Monthly composites like this can underpin regional monitoring, revealing changes to vegetation across the year.


Analysis-ready-data means that organisations can start to benefit from the insights any analysis delivers immediately, without any of the up front heavy lifting. Making this data readily available via an API also means that organisations with their own applications or platforms can simply plug themselves in and automatically ingest data directly and in high volumes. We are also providing consultancy and bespoke product development to help our customers make the most of the opportunities this rich new source of data offers.


 

Satellites in Agriculture

Satellites in Agriculture (SiA) is a collaborative R&D project undertaken by Ecometrica, Environment Systems and Rothamsted Research. With funding from Innovate UK, the project has developed wall-to-wall applications of Sentinel EO derived information products for environmental compliance and productivity monitoring in agriculture.

Within the agricultural sector as a whole, there are a number of potential EO applications, including:

  • Broad-scale monitoring of changes to agricultural production and land use
  • Information about the interface between agriculture and natural ecosystems
  • Commercial data about crops and varieties, leading to production estimates
  • Risk, suitability and change information
  • Precise, timely information for agri-businesses to inform on water and agrochemical requirements, and the optimal timing of operations

The current market for EO derived information products in agriculture is growing fast. Leveraging the increased availability of data and cloud computing capacity presents an exciting opportunity to bring these data products into the mainstream.

Estimated crop cover of potato fields in July (left) and September. Red is bare soil, Dark green full cover and shades between indicating more/less crop cover, important for evaluating harvest timing and planning for desiccant application.

The result of our work on this project so far is a fully automated API-driven processing chain which delivers data products routinely for Rothamsted through EOLab, Ecometrica’s web based application platform. An API means that other application platforms can access our data products too. Having developed the highly scalable workflow the project then went onto to deliver ready to use data products that include:

Production Intelligence

Large scale agri-businesses which have large growing or purchasing operations spread geographically over multiple locations face many challenges. These include monitoring of within season performance between different sites and aggregating that data for effective decision making. Automated processes within our Data Services enable us to tailor the products to deliver precisely the information required and at the right time. Potatoes, for example, are grown both directly by the business and under contract by independent farmers. Businesses that subscribe to our data product feeds can verify planted area, monitor crop establishment and field-scale performance throughout the season. They can also identify problems within fields, predict harvest timing and estimate yield. Within season satellite indicators can be used to provide consistent data across the whole business, improve risk management and reduce monitoring costs.

Regional Crop Mapping

Within season mapping of crop type at a regional scale provides valuable insights for large-scale agri-businesses and government agencies. Crop type mapping can range from consistent mapping of all crops grown within the year, to mapping of specific crops of interest at key decision times.

We tailor the delivery of information from our Data Services for agri-businesses that need up-to-date intelligence on crop production to inform their planning and management. Vegetable growing businesses in the UK can adapt their planting and harvesting schedules in response to market forces reacting to the state of competitors’ crops. We program weekly maps of the extent and estimated growth stage of vegetables across a wider region enabling more informed commercial decisions.

Government organisations that have a regulatory role in monitoring crop types annually, and report on crop presence, diversification and ecological compliance are already using Environment Systems Data Services to support their work. Data that is more scalable and responsive underpins monitoring and policy development.


 

Improving Agricultural Practice

In this IPP UK Space Agency funded project Environment Systems is working with a number of commercial and government stakeholders in the high value agricultural sectors in Peru and Colombia. We have now developed a range of analysis ready data products specifically aimed at regular monitoring of the crops that dominate in these countries of Latin America.

Banana crop

EO4cultivar is changing decision making in the agricultural sector that is helping bring about improved agricultural practice. It is doing this by establishing partnerships, developing data products that provide new knowledge about crops and land management, then transferring that knowledge to change and improve decision making and practice at regional and field level.

Copernicus Sentinel 1 and 2 satellite data are at the core of these product developments. A time series of radar data enables us to identify key growth stages in crops, which helps growers plan agronomic activities and prepare for harvest. Sentinel 2 optical satellite data delivers a number of vegetation indices that detect signs of stress in crops, ahead of when they may be visible to the human eye.

Environment Systems Data Services enables agri-businesses to receive up-to-date crop monitoring information in a format they are familiar with (data, alerts, maps) and compatible with their own crop management systems, putting these ready to use data products directly into the hands of their growers.

Agri-businesses and regional advisory services are now using these products directly themselves and to dispense advice, observations and insights to smallholders and others in supply chains for these export crops.

At the time of going to press we are working on automating the routine production of data products for a number of crops including asparagus, grapes, bananas and potatoes. In each case all the data processing will happen within Environment Systems Data Services.

  • Field-level production status: for yield estimates, growth stage, harvest timing
  • Field-level leaf stress estimates
  • Field-level metrics aggregated to farm/regional scale
  • Field-level crop maps with inter-seasonal change
  • Regional maps of grape field types (Pisco v Table)
  • Regional cropped area maps
  • Crop specific estimates of area and yield
Data insights to growers
Putting stats and insights directly into the hands of the growers


 

Monitoring on a National Scale

The DFMS (Drought and Flood Mitigation Service) project is based in Uganda and is an IPP UK Space Agency funded project. The extreme conditions caused by droughts and floods demand high quality information to direct mitigating action on the ground. The project aims to provide timely and improved meteorological, hydrological, and EO satellite information in the form of current observations, forecasts and historical data. A kind of ‘early warning system’ to provide decision makers with practical information that will improve knowledge and help mitigate against droughts and floods.

On this project, Environment Systems Data Services is providing analysis-ready Sentinel-1 and Sentinel-2 data for the whole of Uganda. The data are is ingested by the DFMS platform and used to automatically produce a range of products including monthly Sentinel-2 derived NDVI composites. Sentinel-2 passes over Uganda in three paths, or swaths, every 5 days. The images from these swaths are combined to produce aggregate NDVI maps. Using these maps, decision makers can monitor the state of green vegetation throughout Uganda; growers can see the progress of crops, the impact of drought and much more. The resolution is sufficient to provide regional analysis and even down to a field level. Kakira Sugar, one of the project partners, is using these composites to monitor their sugar cane estates.

Karamoja burn areas
Burn areas in the Karamoja region of Uganda
The data are also being used in the Karamoja region where burning prior to the wet season is a common agricultural practice to encourage fresh growth of grazing pastures. However, the extent of burning, and its impact on the environment, is unknown. Consequently, Sentinel-2 images are being processed to produce a ‘Burn Area Index’ that is sensitive to the charcoal signature that exists following a fire. As a result, large areas can be analysed and the location and extent of burning quantified.


 

Habitat Mapping for Onshore Wind Farms

Onshore wind farm developments face considerable challenges not least the planning process which rightly scrutinises prospective sites and their environmental impact. Environment Systems is a long-established provider of services to developers which include Phase 1 habitat surveys and protected species surveys that inform site design and mitigation measures required during construction.

Onshore wind
Satellite data helped to reduce the cost of habitat mapping by 50%
Recently our team has been using Environment Systems Data Services to validate existing but out of date Phase 1 Habitat surveys. A site of 1,300 hectares (13 sq km) was simply too big to re-survey cost effectively so we used Sentinel 2 multispectral imagery together with the existing survey to carry out the habitat segmentation. This highlighted the areas of change across the entire site. Of course the sophisticated techniques we use in the office need some validation and standard NVC (National Vegetation Classification) surveys were carried out on the areas highlighted by the updated habitat map. In most instances these areas consisted of clear-fell within plantation forests and some areas where improved drainage had led to the introduction of grazing or further woodland planting. The time saved by using satellite imagery also delivered a 50% cost saving.


 

Potato Crop Identification

In the UK levies are paid to farmers growing potatoes by the Agriculture and Horticulture Development Board (ADHB). This covers all varieties of potato grown within a season. ADHB are investigating a monitoring program which utilises satellite remote sensing to validate grower declared fields. A pilot project carried out by Environment Systems this summer considered a range of optical and Synthetic Aperture Radar (SAR) satellite data to demonstrate their potential for detecting potato fields.

Potato crop detection
A potato detection algorithm enables the crop to be precisely delineated from surrounding crops
Four locations in potato growing areas were used to demonstrate the quality and scalability of the process. Time series Sentinel 1 and Sentinel 2 data were downloaded from Environment Systems Data Services. The data was combined and a potato crop detection algorithm was applied based on the crop’s known phenological characteristics. The exercise was a success and demonstrated that the detection algorithm was able to delineate potatoes from surrounding crops at a national scale.


 

More Automation Better Interpretation

One of the benefits that the Sentinel satellites deliver is regular coverage. That means the data can be
reliably used for change detection. The Sentinel 1 radar satellites are particularly useful as they are not affected by cloud cover. We now have a mature, fully automated processing workflow for Sentinel 1 SAR data which removes some of the ‘speckle’ noise and makes the imagery more interpretable. As a result we can now deliver monthly composite maps that are useful in the interpretation of biomass, particularly crops. Automation not only delivers a better more consistent image layer but also reduces the cost of production. This means less time spent processing and preparing data and more time on the interpretation, statistical analysis and algorithm development. The more our customers can understand about their crops the better the evidence base will be for making land management, commercial or policy decisions.

Natural Capital Accounting

SoNaRR (State of Natural Resources Report) commissioned by the Welsh Government is country-wide assessment of the health and resilience of ecosystems and the first assessment of the extent to which Wales is sustainably managing its natural resources. Environment Systems was involved both in a pilot mapping project and subsequently in creating opportunities mapping which develops the evidence for Area Statements.

SoNaRR reported that the full value of natural resources and ecosystems were not fully considered in decision making and also concluded that new tools and techniques would be required to understand the value of the contribution that ecosystems make, sometimes referred to as natural capital accounting. By providing valuations of natural capital, decision makers can take better account of the environment in their plans to allocate resources, to develop and promote well being and the growth of the economy. Natural capital accounts present the value of the environment in an accounting format that is familiar to business and policy leaders enabling environmental issues to be considered alongside economic effects when gauging the feasibility of actions.

Earlier this year NRW (Natural Resources Wales) commissioned a feasibility study from Vivid Economics with Environment Systems as a partner. The objective of this study was to develop strategic thinking, a framework and options for progressing natural capital approaches, especially natural capital accounting, including the identification of appropriate data sets and methods. There was a particular emphasis on understanding the requirements of users and the future uses of accounts in the context of local scale that the Area Statements work within.
natural capital accounting tools
The table above summarises the features of some selected natural resource accounting tools. The tools were appraised for their potential added value beyond the features of the existing programme of NRW natural capital work, especially NRW’s SoNaRR stock and opportunity mapping.

The results of the work are enabling NRW to build on natural capital approaches in its delivery of the requirements of the Environment (Wales) Act 2016, in particular Area Statements, and in its work more widely. This will enable NRW to take natural capital accounting forward in a targeted way that works best for Wales.

Trees Outside Woodland

Sometimes we get involved in projects with a large research element. Current work for the Scottish Government and Forestry Commission Scotland is an example. It focuses on determining how the Scottish Government can use remote sensing technology to assess the amount, location and distribution of trees outside areas classified as Scottish woodlands.

trees that fall outside woodland
Trees are a valuable Scottish resource, mapping their location outside woodlands is a challenge
Forestry Commission Scotland monitors woodland and produces statistics and information on woodlands over 0.5 hectares and an annual map is publically available. This information is used to inform management and investment within the forest sector that contributes £1bn to the Scottish economy, and also informs a number of other environmental projects. However there is only limited information available on smaller areas of trees, not found in classified woodland areas and are less than 0.5 hectare, such as lone trees and hedgerows. This leaves a significant evidence gap, weakening Scotland’s capacity to account for its carbon stocks accurately, plan and control plant health outbreaks, to plan for urban trees impact on air quality and to plan effectively for new woodland creation and woodland expansion.

The availability of new remote sensing technologies offers the prospect of being able to quantify and map these tree features and to fill the evidence gap. In our research we are investigating a suite of datasets representing different sensors (e.g. radar vs optical) and resolutions, examining their ability to detect lone trees and small stands of woodlands not included in the National Forest Inventory.

Within the project we are developing a test methodology for determining the best mix of remote sensing technologies, their practical accuracy and cost effectiveness plus recommendations for the way forward.

Mapping for policy, recovery and resilience

Darwin Plus, sometimes referred to as the Overseas Territories Environment and Climate Fund, is open to any organisations that wish to embark on a project which will benefit one or more of the British Overseas Territories by protecting and enhancing their biodiversity or addressing wider environment or climate-related issues.

This project is the result of a joint bid by Environment Systems, The Government of the Turks and Caicos Islands (TCI), National Parks Trust of the British Virgin Islands (BVI) and the Joint Nature Conservation Committee (JNCC).

The project will provide evidence to develop policy to aid post-hurricane environmental recovery and enhance future resilience to natural disasters. It will use satellite data to map and model the marine and terrestrial environment in the TCI and BVI, both before and after hurricanes Maria and Irma which caused so much devastation in 2017.

The project will share experience and learning to develop both island groups’ expertise in relevant techniques and be integrated closely with other UK Government supported projects in the BVI and TCI.

The Turks & Caicos – this low mainly flat limestone island group has extensive marshes and mangrove swamps and over 128 square miles of beach front
Ecosystem goods and services, derived from biodiversity, are crucial to the islands’ economies, supporting tourism, food provision and providing protection against the effects of extreme weather events. The natural environment is susceptible to damage from both human activities and natural disasters such as hurricane-generated storm surges and flooding. The importance of protecting these natural assets has been brought into sharp focus by the recent hurricane damage and the impact on the islands’ economies.

A major part of this project will focus on building resilience. This will be achieved by building the capacity of the island governments to use remote sensing outputs to undertake detailed mapping of terrestrial and marine environments themselves, both to evaluate hurricane impacts and highlight opportunities for habitat restoration. Three workshops will be held in the islands, with a further workshop programmed to take place in our head office. The project will run until early 2020.
