Summary

This video training covers the management and reclamation of swamp ecosystems in Indonesia, focusing on areas like Sumatra and Kalimantan. It discusses the ecological characteristics of swamps, including their unique vegetation and water conditions. The script highlights Indonesia's vast swamp lands, the impact of reclamation by both the government and local communities, and the transition from rice cultivation to other crops like coconut and palm oil. The video provides insights into the historical and ongoing efforts to develop swamp areas for agriculture and industry, offering a detailed perspective on swamp irrigation systems and their modern usage.

Takeaways

• 😀 Ecosystem of wetlands, including both tidal and non-tidal areas, is the primary focus, with unique vegetation based on water conditions.
• 😀 Indonesia has vast wetlands covering approximately 33.4 million hectares, with 60% being tidal swamps.
• 😀 Around 40% of Indonesia's wetlands are non-tidal swamps, such as Lebak swamps.
• 😀 Nearly 9 million hectares of tidal swamps in Indonesia have been reclaimed, with various stakeholders involved, including the government, local communities, and private companies.
• 😀 The reclamation efforts by the government cover about 1.3 million hectares, while local communities, mainly the Bugis and Banjar, have reclaimed around 2.4 million hectares.
• 😀 Private companies have developed about 5.3 million hectares for plantations, primarily oil palm, industrial forest plantations, and shrimp farms.
• 😀 A map indicating the distribution of wetlands in Indonesia shows higher concentrations around the coastal areas of Sumatra and Kalimantan.
• 😀 Wetland development in Kalimantan began in the early 20th century, with reclamation efforts by indigenous people noted as early as the 1930s.
• 😀 The government's wetland reclamation efforts focused on areas further inland, away from riverbanks, with larger irrigation systems to manage water flow.
• 😀 Since the 1990s, private sector involvement has surged, with significant expansions in wetland development for agriculture and shrimp farming, reaching over 5 million hectares by the 2000s.

Q & A

What is the general definition of a wetland ecosystem?

A wetland ecosystem is a type of natural land characterized by its wet or submerged conditions. It can be influenced by tidal movements or not, and the water may be saline, brackish, or freshwater. These ecosystems support unique vegetation adapted to the water conditions.

How extensive are the wetlands in Indonesia?

Indonesia has a vast wetland area of approximately 33.4 million hectares. About 60% of this area is coastal tidal wetlands, while 40% is non-tidal wetlands, also known as Lebak or freshwater wetlands.

What percentage of Indonesia's tidal wetlands have been reclaimed?

Around 9 million hectares of tidal wetlands have been reclaimed in Indonesia. Of this, approximately 1.3 million hectares were reclaimed by the government, 2.4 million hectares by local populations (mainly from the Bugis and Banjar ethnic groups), and 5.3 million hectares were developed by private companies, mostly for oil palm plantations and industrial tree plantations.

What is the geographical distribution of wetlands in Indonesia?

Wetlands in Indonesia are primarily found along the coastal areas of Sumatra and Kalimantan, including parts of West, Central, and South Kalimantan. There are also some wetlands in North Kalimantan and the Papua Islands.

When did the development of wetlands in Kalimantan begin?

The development of wetlands in Kalimantan started as early as the 20th century, and even before that, it was initiated by indigenous populations. The reclamation by the colonial government began in the 1930s, focusing on Sumatra and Kalimantan.

How was wetland reclamation carried out by the local population and the government?

Local populations typically reclaimed wetlands near riverbanks, extending their drainage systems progressively further from the river. In contrast, the government focused on reclaiming wetlands farther from the riverbanks, developing them into irrigation areas.

What are the typical land classes in wetland reclamation?

Land in wetland reclamation projects is often classified into classes based on its suitability. The land developed by local populations typically falls under Class A and B, while government reclamations focus on Class B and C lands, which are farther from rivers.

What are some examples of wetland reclamation areas in Indonesia?

Examples of reclaimed tidal wetlands in Indonesia include areas in South Sumatra and South Kalimantan, such as Jejangkit and Rantang irrigation areas, as well as the Tabungan area. These regions have been developed since the 1980s.

What role did private sectors play in wetland development in the 1990s?

In the 1990s, private sectors became the main drivers of wetland development, particularly for oil palm plantations and industrial tree plantations, significantly expanding the reclaimed wetland areas.

How much wetland was developed in the 2000s for agricultural purposes?

In the 2000s, the development of wetlands for agricultural purposes surged, with approximately 5 million hectares of land developed for plantations, and around 450,000 hectares for shrimp farming and other aquaculture activities.
