Abstract

This paper provides a review of the Toba highland peatlands, focusing on their characteristics, environmental impacts and historical significance. The Toba area was influenced by a super volcano eruption around 74,000 years ago, which resulted in global cooling and the deposition of pyroclastic materials known as the Youngest Toba Tuff. The peatlands in the region formed south of the caldera and are characterised by varying extents and thicknesses. Radiocarbon dating indicates that the peat in Toba highland is approximately 20,000-30,000 years old, making it a valuable carbon stock and a record of the past. However, the drainage of peatlands has led to significant environmental degradation. It has resulted in increased CO2 emissions, reduced water supply for local farmers, loss of biodiversity, air pollution from open fire burning practices, and an increased fire hazard. Understanding the environmental impacts and historical significance of Toba highland peatlands is crucial for conservation efforts and sustainable land management practices.

Abstract

Regenerative agriculture has recently gained popularity as a promising approach to achieving sustainable agriculture and ensuring food security. This article reviews scientific papers published between 1986 and 2024, as well as popular media, including the documentary "Kiss the Ground," released by Netflix in 2020, which successfully introduced the concept of regenerative agriculture to a broader audience. The article explores the definition, principles, and prerequisites of regenerative agriculture and examines how this concept can be adapted in Indonesia, given the challenges faced by conventional agriculture and the potential for integration with digital technology. This study used 342 papers discussing regenerative agriculture and those related to regenerative agriculture terminology using the virtual tool map, Research Rabbit, and selected 10 most papers relevancies. The review concludes that regenerative agriculture essentially encompasses or aligns with previously established concepts, including agroecology, organic farming, conservation agriculture, climate-smart agriculture, and traditional agricultural systems often associated with environmentally friendly and sustainable practices. In the Indonesian context, farming systems like Subak in Bali, integrated farming in Java, and climate-smart farming in East Nusa Tenggara can be classified as forms of regenerative agriculture. However, the prerequisites for regenerative agriculture to produce commercial-scale yields may vary across different agroecosystems, as each has its specific needs.
