Mapping Land Use Change Impacts in the Philippines

Exploring land use change impacts in the Philippines using satellite imagery, GPS synchronization, and ground surveys.

00:00:00 Tracking Land Use Change Impacts on the land and its people. Assessing the accuracy of previous land cover updates in the Philippines using satellite imagery. Comparison of forest cover estimates between 1987 and 2002.

🌍 The lack of appropriate tools for land analysis is a barrier to effective resource management.

πŸ“‘ The first ever land cover update using satellite imagery was conducted in the Philippines in 1987, funded by the World Bank.

🌳 Forest cover in the Philippines decreased from 1987 to 2002, but there were discrepancies in the data due to different classification methods.

00:08:35 This video discusses the method used to track land use change impacts on the land and its people. It covers the challenges faced and the techniques employed, such as GPS synchronization and satellite data processing. The speaker also mentions the use of ground surveys and drone imagery.

🌍 The video discusses the method of synchronizing clocks to link GPS time with the location of photos, allowing for accurate tracking of land use change.

🌳 Different land cover classes, including mossy forest, primary forest, secondary forest, and plantation forest, were identified through ground and aerial surveys.

πŸ›°οΈ Sentinel data from the European Space Agency was used to update the land use information, with the help of the Cento agre protocol, which included drone and ground validation.

00:17:14 Tracking changes in land cover and its impact on the environment and agriculture. Significant decrease in grasslands and natural forest, while crops like corn, sugar cane, and rice have expanded. Overall, a net gain of 24,000 hectares in tree cover.

πŸ“Š Between 2005 and 2018, there were significant changes in land cover, including an increase in corn and rice production, a decrease in grasslands, and a stable forest cover.

🌳 While there was an overall gain in tree cover, there was a significant loss of natural forests, which were converted into secondary forests. Plantations for trees and pine also decreased.

🌿 The decrease in grasslands can be attributed to the improved classification methods that used a season of images instead of relying on a single image. Perennial crops such as pineapple and rubber saw an increase, while shrub lands and grasslands decreased.

00:25:50 The video discusses the impact of land use change on the environment and people. It highlights the negative effects of dynamic tree cover, corn cultivation, and lack of grasslands. The importance of accurate data, stakeholder involvement, and access to information are emphasized.

🌳 The type of tree cover discussed in the video is dynamic and volatile, and not beneficial for the environment.

🌽 The cultivation of corn in certain areas is causing negative impacts on the soil and the farmers involved.

πŸ—ΊοΈ Lessons learned include the importance of field data, different classification methods, open documentation, involvement of local stakeholders, and access to data and resources.

00:34:27 This video discusses the impact of tracking land use change on the land and its people. It explores the use of data and technology in monitoring land cover and emphasizes the need to consider the consequences of development on the environment.

🌍 Monitoring land use change impacts on the land and its people is crucial.

πŸ“Š Using remote sensing and drone technology can help monitor land cover at large scales.

🌳 The destruction of old-growth forests due to road development highlights the importance of making informed decisions.

00:43:06 The video discusses the challenges faced in mapping land use and the importance of regular updates. It emphasizes the inclusion of local knowledge and the need for a specific approach for Indigenous communities.

🌎 The process of land mapping has been institutionalized and opened up for access, but detailed classification requires more resources.

πŸ“Š Regular updates and monitoring of land use are crucial for effective land use policies and regulations.

πŸ‘₯ Local communities, including indigenous groups, are integrated into the land mapping process to ensure their knowledge and management practices are respected.

00:51:49 Tracking Land Use Change Impacts on the land and its people. Lecture on the challenges of mapping and accessing data, importance of local knowledge, and upcoming talks.

πŸ“š The video discussed the importance of tracking land use change impacts on the land and its people.

πŸ—ΊοΈ Dr. Jose Andres ignasio emphasized the challenges of mapping and accessing data related to land use change.

🌍 The talk highlighted the significance of incorporating local knowledge and community voices in understanding and addressing land use change.
