The rhinos haven't been seen in more than a quarter of a century and conservationists had feared the Sumatran was extinct. But, six females and one male rhino are now known to live in the Mount Leuser National Park, which is on the northern tip of Sumatra. More

Forest Cover

Statement regarding current status of the study of deforestation rate in the mainland of Aceh Province - Banda Aceh 4 November 2009

1. LIF has updated the forest and land cover map for the mainland of t5he province of Aceh, using Landsat data for the year 2009.

2. The result show a forest loss or conversion of forest to non-forest uses of 96,554 ha between 2006 and 2009

3. The deforestation rate has been highest in the districts of Pidie Jaya and Sbussalam.

4. Of the 96,554 ha that have been lost, 54,466 ha are in non-forest land (APL). Deforestation in production forest (HP) has been 16,165 ha, in limited production forest (HPT) 193 ha, in protection forest (HL) 21,455 ha, and in the Leuser National Park (TNGL) 3,124 ha. Of the 21,455 ha lost in HL, 4,005 ha are in Gayo Lues, 5,352 ha in Pidie Jaya, 3,432 ha in Aceh Besar and 2,127 ha in A Tengah.

5. The forest cover in 2006 was estimated at 3,284,786 ha. In percent per year the deforestation rate over a four-year period from 2006 to 2009 is less than 1%. (This is lower than the national average for a similar period (abt 1.2 %, see referenec documents at Dephut web site, Badan Planologi)

6. All LIF data is available for checking. LIF is continuously updating the forest cover information as new satellite imagery and feedback from field staff becomes available.

Aceh Deforestation and Land Cover statistics 2009

SUMMARY

The LIF GIS section has completed a new forest cover and partial land cover update of the 2006 forest cover map for all the Kabupaten in Aceh province (with the exception of Kepulauan Simeuleu, Sabang and Pulau Nasi " which are still in progress). The 2009 update, which covers all areas in mainland Aceh shows that there was a 96,332 ha of net forest loss in Aceh where forest cover was removed, and the land converted to non forest uses.

In this analysis, care has been taken to ensure that the observations in change in forest land are real changes rather changes that result from differences in data processing methodologies, or different levels of map accuracy caused by the use of different sets of satellite imagery as the basis for interpretation.

The new update was produced by standard screen visual interpretation of mid infra red (MIR) composites of SPOT 2007 10 meter resolution images, then comparing and updating this with MIR composites of Landsat data from various dates in 2009. The 30m Landsat data was pan sharpened to 15meter resolution to improve data quality.

The forest cover maps produced and field checked by FFI based on year 2008 Landsat were also incorporated and this data itself was in turn updated with the new 2009 Landsat data.

New Landsat data is made available continuously, the technique for analysis gets refined and we get feedback regularly from the field. All this means that the results presented here are not "final" " they are being improved on continuously. (With this paper we also invite colleagues and partners to comment and improve where they see the need.)

Nevertheless, we consider the results presented here as reliable enough to provide a safe base for discussions regarding various kinds of follow-up action.

This robust method  allows comparing "like with like", Table 2 represents an accurate estimate of the  actual 4- year change in forest cover in mainland Aceh, which shows a net decline in forest area of 96,332 ha over the four year period.

Expressed as a compound deforestation rate in percent per year (2006: 100%) over four years, the rate is about 0.77%

Although any comparison between separate estimates of deforestetation  is fraught with methodological difficulties owing to differences in data quality etc, it is still significant that for the period from 2000 to 2006 the deforestation rate has been estimated to be in the magnitude of 1.2 to 1.5 % per year. The indication from this present analysis" and the uncertainty here is underlined " is that deforestation still proceeds, but that it seems to be slowing down. It is also lower than the national average deforestation rate. (See Dephut Penghitungan Deforestasi Indonesia 2008)

The above table gives additional detail to the information in Table 4 by showing deforestation by Kabupaten and official forest function or zone area. According to the new statistics there has been an alarmingly high rate of forest loss in HL in both Pidie and Gayo Lues.

There have also been significant forest losses in HP areas in five Kabupatens.

All data, maps and statistics are available on request.

LIF encourages transparency in forest resource accounting, and all spatial and statistical data produced by this study are freely available especially in order to resolve any eventual errors and inaccuracies. The analysis continues under coordination by Aceh Green Secretariat.
