Origin:Capability Enhancement in Using Geographic Information Systems in Central America 2013-2016

In 2013, International Cooperation and Development Fund (Taiwan ICDF) conducts Geographic Information System (GIS) Project with Honduras,El Salvador and Nicaragua. ICDF cooperations with Center for Space and Remote Sensing Research,Taiwan National Central University (CSRSR-NCU), applying satellite, remote sensing and GIS to assist these countries.There are project of water quality monitoring in Nicaragua, land resource planning in El Salvador and environment resource management in Honduras.

In 2015-2016, rainfall decreased in Honduras result from climate change and global warming. Growth period was extended causing the population increase of bark beetles. As the result, many pines had been damaged.

In 2015, CSRSR uses satellite image to find that pines was infected by bark beetles in Honduras. Although the pest damage was seriously, there is no professional department of pest management at that year.

Therefore, Honduras Government makes an effort to solve this problem by satellite and GIS technique with Taiwan. In this year, the professional team of ICDF has dealt with mission assigning and problem analyzing. Taiwan and Honduras Government signed the Honduras Forest Pest Control Project (HFPCP) in 2018 ,that a 4-year project. HFPCP will be done by 2021.

Now:Honduras Forest Pest Control Project 2018-2021

ICDF and CSRSR keep going cooperation in HFPCP with the aim of reducing the warning time of pest in Honduras. That means, after being affected by pests somewhere in Honduras Pine Forest, it usually takes a month to be detected and reported back to Honduras Forest Institution(ICF). Now the project aim to reduce the time to one week through GIS technology.

The execution method is mainly divided into four aspects:

  1. Collection information of forest.
  2. Development of forest pest management technique.
  3. Establishment the decision support system.
  4. Technique transfer and training.

1.Collection information of forest.

Collect forest health information, including collecting meteorological data, map data, and pest outbreak records in Honduras, to understand the current situation and establish mathematical models.In addition, it can assist Hongguo to establish a national greenhouse gas report for future use at the UN General Assembly.In addition, three forest management demonstration sites will be selected.

Demonstration site setting rules
No pests Pests
Without forest management Demo site3(Olancho)
With forest management Demo site2(Yodeco) Demo site1(UNACIFOR)

The purpose of the demonstration site is to compare whether forest management techniques are effective against pests. The demonstration sites usually work with local private forest landowners to set up miniature weather stations and bark beetle attractors(Lindgren Funnel Traps), and set up cards to introduce which kind forest management measures adopted by the site.

2.Development of forest pest management technique.

The development of forestry pest management technology includes several advanced researches to understand the diffusion patterns, outbreak mechanisms, and risk map production of bark beetles. First, by understanding the data of past pest outbreaks, establish rules for predicting future pest outbreaks and establish an early warning system. At the same time, there are strategies for responding to outbreaks, including the establishment of a return mechanism and loss investigation techniques.

3.Establishment the decision support system.

The decision support system is simply a GIS map platom that can be used to put on collected or generated images. Including past pest outbreak records, climate data, forest fire locations, up-to-date instant notifications, satellite imagery, etc., providing ICF decision makers assign manpower and resources to control pests.

4.Technique transfer and training.

Because the project involves a variety of skills, including GIS map operations, algorithm architecture, interpretation of graphics, etc. The CSRSR team will provide teaching and discussion to Honduras ICF during the wet season each year (less pest in wet seasons). In addition to familiarizing the ICF with the use of these technologies, it also strengthens their ability to develop new technologies on their own in anticipation of more effective pest control in the future.
