Sendai Framework Ad hoc indicator C-2Fo In Detail

This page provides a partical use of GWIS for national focal points to report on the number of hectares of forests damaged/destroyed by fire in reference to Target C of the SFDRR where country data for estimating directing economic loss is not available.

The Sendai Framework

The SFDRR was adopted at the Third UN World Conference in Sendai, Japan, on March 18, 2015. The framework aims to achieve the substantial reduction of disaster risk and losses in lives, livelihoods and health and in the economic, physical, social, cultural and environmental assets of persons, businesses, communities and countries over the 15 years leading to 2030. More information on the Sendai Framework is available here.

The framework sets four priorities for action and seven global targets to reduce the risk of disasters and to avoid the increase in the level of existing risks. The seven targets are assessed through a set of 38 indicators.  Government officials and relevant stakeholders involved in monitoring national progress have been designated to report on in the SFM, to support the assessment of global progress in the reduction of risk and losses. Country coordinators also have the option to add custom indicators and targets, which are nationally defined instruments to measure the implementation of the Sendai Priorities, to support states in reporting the relevant data they have.

 

SFDRR Sub-indicator C-2Fo/C-2Foa of Target C

Target C of the SFDRR has been incorporated to reduce direct disaster economic loss in relation to global gross domestic product (GDP) by 2030. It refers to economic losses to the agricultural sector, productive assets, housing sector, critical infrastructure, and culturage heritage. 

Indicator C-2 measures the impact of disasters on agricultural production and assets. As agriculture is understood to include the crops, livestock, fisheries, apiculture, aquaculture and forest sectors as well as associated facilities and infrastructure, C-2 is the sum of five sub-indicators. Sub-indicator C-2Fo measures loss in forests damaged or destroyed by disasters.

Full reporting for the Target C indicators would require data collected from different government ministries, agencies, and/or other relevant stakeholders such as Non-governmental ogranisations (NGOs). It is likely that the ministry/agency responsible for national forest management would be responsible for collecting the data that states need to report on sub-indicator C-2Fo.

However, reporting country data on economic loss in forest damaged or destroyed by disasters may not be feasible, especially in developing countries which experience frequent forest fires over large areas. This was highlighted in the Sendai Framework Data Readiness Review conducted in 2017, in which 87 countries participated, which found that no single country has all the data required to report on all the targets, and that datasets on economic losses are less available than physical damage and human impact indicators. In countries where there is no methodology to assess economic loss of forests, the TGN therefore specifies that a physical damage indicator, C-2FOa, which measures the number of hectares of forests damaged/destroyed by disasters (disagregated by hazard) will be accepted in lieu of the corresponding estimated economic loss.

 

In Detail: acccesing data for C-2Fo (Fires)

1. Go to GWIS using the following URL: https://gwis.jrc.ec.europa.eu, and select the option Country Profiles under the Apps drop-down menu in the main navigation panel (see figure 1).

Figure 1: GWIS main page.  In the top menu, the option "Country Profiles" appears under the "Apps" drop-down menu.

 

2. Once the new window appears displaying the different regions of the world, select the desired country (Bolivia for example) under the region of interest (e.g. South America) from the drop-down list, and scrolling down to the desired country of interest (see Figure 2).

Figure 2: Selection of desired country under the drop-down menu below each geographical region of interest.

 

3. After selecting the desired country, the landing page of the desired country appears presenting general data on the country.  Click on the "Country charts" menu on the left margin to proceed (see figure 3).  It may be that initially, this option appears with a dark grey color font.  Nevertheless, it is selectable when clicked and will turn to white color font.

Figure 3: Initial country profile page displaying general information regarding the selected country.

4. A new window will pop up presenting two tables of data.  Click on the "Go to the charts" button at the bottom of the left table. (see figure 4)

Figure 4: Country chart window with two tables.

 

5.  Once the new window pops up, slide the circle in the top left slide bar to span the period from the year 2005 to 2019.  Then scroll down to the graph entitled ‘Yearly Burned Area by Landcover – [2002-2019]’.    Hover over the download icon, and download the data as CSV.  (see figure 5)

Figure 5: Downloading the data from GWIS into an excel file in csv format.

6. Open the excel file that was downloaded. The file name will start with ‘MCD64.006’, refering to the MODIS Collection 6 burned area product MCD64 A1 from which burnt area statistics are computed.  MODIS (or Moderate Resolution Imaging Spectroradiometer) is a key instrument aboard the Terra and Aqua satellites. These two satellites are viewing the entire Earth's surface every 1 to 2 days, acquiring data in 36 spectral bands, or groups of wavelengths   The data presented in GWIS employs a combination of daily 500m MODIS surface reflectance and 1km MODIS active fire observations, and applies dynamic thresholds to composite Terra and Aqua imagery generated from a burn-sensitive vegetation index from MODIS 1240 and 2130 nanometer bands and a measure of temporal variability (GWIS, 2021). The algorithms’ coupled use of active-fire and reflectance data enables it to adapt regionally and over varied ecosystems, and peforms substantially better in reducing the number of unclassified grid cells due to  cloud contaminated observations compared to the heritage Collection 5.1 MODIS products (Giglio et al, 2018). 

Note that the data being opened from a csv file will appear in one single column in Excel at first (see figure 6 ). Select the "Data" menu at the top, then select all data in column A, and use the ‘Text to data‘ function and follow the Convert Text to Columns Wizard‘s instructions.

Figure 6: Transforming the data from csv format in excel for subsequent processing.

A new pop-up window will appear with options for this transformation. Make sure to use the right delimiter, which is comma in this case and click finish (see figure 7).

Figure 7: Pop-up window in excel to complete the conversion of the data from csv format in excel for subsequent processing.

After the transformation from csv data has been completed, the values corresponding to the total burnt area in hectares of forest for years 2015 onwards can be reported as physical damage indicators under sub-indicator C-2Fo. In the SFM, select data entry option ‘Enter hectares manually & monetary value to be calculated’, and the system will calculate an estimate of corresponding economic loss. To include grasslands in C-2Fo reporting, add the yearly values for burned grass/shrubland to those for forests (see figure 8).

Figure 8: Excel table with country data for several years

7. Member states are encouraged to include baseline data for Target C for improved analysis of progress over time. To calculate the mean annual burned area for the period for 2005-2014 in Excel, use the AVERAGE function and select cells corresponding to yearly burned area between the years 2005 and 2014 (see figure 9).

Figure 9: Selection of data range for calculation

8. To calculate percentage change in any year relative to the baseline, first create a table similar to the one that can be seen in figure 9, containing the data related to the years 2015-2019 and the value for burned forest area and the baseline that was calculated earlier . Subtract the baseline value from the number of hectares burned for any year, and divide by the baseline. Ensure the cell format is converted to ‘Percentage’ (see figure 10).

Figure 10: Creating the table to calculate the percentage of change per year related to the baseline.

 

In the example below, we can see that Bolivia experienced a 70.2% increase in number of hectares forests damaged/destroyed by fires in 2019 compared to the 2005-2014 (pre-Sendai) baseline.    A chart can be created to present the data for the years 2015 to 2019 in relation to the 2005-2014 baseline as shown in figure 11.

Figure 11: Example of result displaying baseline and data for different years between 2015 and 2019.

Strengths:

• The indicator provides a simple means of reporting the estimated total yearly number of hectares of forests damaged or destroyed by fire.

• GWIS data covers all countries and can be downloaded free-of-charge and without registration.

Limitations:

• The indicator does not distinguish between the desirable disaggregation criteria totally destroyed or damaged burnt areas and forest type.

• The indicator does not distinguish between wildfires and controlled fires for forest management and/or agricultural clearing.

• Country burned area statistics in GWIS may not always be available for the previous year at the start of the year. The SFM requires data for targets A-E from the previous calendar year to be reported by 31 March on an annual basis. Data for target C-2Fo will therefore not be included in global overviews for that reporting year, but will be included in the overall assessment at the end of the Sendai Framework in 2030.

Flowchart for this procedure

 

Sendai Framework Ad hoc indicator C-2Fo Intro

Fires continue to destroy thousands to hundreds of thousands of hectares of forests and wildlands around the world every year.  Furthermore, the United Nations Development Programme (UNDP) recognises that global warming will lead to an increase in the number and severity of forest fires in years to come.   As a first step to address the challenges of wildfires, it is important to assess their geographical location and their severity.  This information can be useful to implement restrictions on land use and to identify measures to ensure the recovery of such wild areas.   

The Global Wilfire Information System (GWIS) is a joint initiative of the Group on Earth Observations (GEO) and Copernicus Work Programs. GWIS aims to bring together existing information sources at the regional and national levels in order to provide a comprehensive evaluation of fire regimes and fire effects at a global scale, and support operational wildfire management from national to global levels. In 2021, GWIS launched its Country Profiles application which provides national-level statistics and historical data of fires, including yearly burned area by landcover class statistics generated from MODIS and ESA land cover products.

The historical data included in GWIS can be used to track the historical trends of forest fires in any country of the world in the last two decades.  Such data can be used to elaborate an ad-hoc indicator for the Sendai Framework Monitor that governments use to report on progress in the implementation of this framework.  The Sendai Framework includes seven targets and indicators have been designed to capture trends over the years.  One of those indicators addresses the trends in the number of hectares that have been burnt on an annual basis.  

This page provides a practical use of GWIS for national focal points to report on the number of hectares of forests damaged/destroyed by fire in reference to Target C of the SFDRR where country data for estimating directing economic loss is not available.

This procedure is designed to be used by those staff at government agencies in charge of compiling and entering information related to specific Sendai Framework indicators. Specifically, for those who have to enter data on indicator C-2Fo related to the impact of wildfires. 

The Sendai Framework for Disaster Risk Reduction 2015-2030 (SFDRR) is the global blueprint for disaster risk reduction (DRR), which recognises that each State has the primary responsibility to prevent and reduce disaster risk, including through international, regional, subregional, transboundary and bilateral cooperation. Member states are encouraged to report on their progress towards the seven Sendai Framework global targets using the online Sendai Framework Monitor (SFM).

Geographical applicability:

This Ad-hoc indicator can be applied in most countries of the world, at the national or provincial level.
