Analysis Of Medan City Land Cover Changes In The Period 2000 - 2011
Introduction
Medan, the capital city of North Sumatra, Indonesia, has experienced significant land cover changes between 2000 and 2011. These changes have been influenced by various factors, including land use, economic policies, and population growth. In this article, we will analyze the changes in land cover in Medan City during this period and discuss the impact of these changes on the environment and the community.
Land Cover Changes in Medan City
A study conducted by Monnica Lestary Zalukhu, guided by Rahmawati and Abdul Rauf, used the Geographic Information System (GIS) and the Analytical Hierarchy process (AHP) to analyze the changes in land cover in Medan City. The results showed that there were several types of changes in land cover that occurred in Medan City, including:
- Dry agricultural land transformed into dry agricultural land with bushes
- Rice fields converted into residential areas
- Secondary mangrove forests converted into fish ponds
- Bushes transformed into fish ponds
- Shrubs transformed into plantations
The biggest change occurred in dry agricultural land mixed with bushes, which increased by 552.99 ha. This change was greatly influenced by economic policies, rapid development, and increasing demand for land for settlements.
Impact of Land Cover Changes
The significant changes in land cover in Medan City have a wide range of impacts on the environment and the community. Some of the impacts include:
- Reduction in agricultural productivity, which can affect regional food security and increase dependence on food supply from outside
- Loss of green areas, such as mangrove forests, which can disrupt the balance of ecosystems and increase the risk of natural disasters, such as flooding
- Decrease in biodiversity, which can have a negative impact on the ecosystem and the community
The Need for Sustainable Policies
Given the impact of land cover changes, it is essential for the government and stakeholders to implement sustainable policies. Good land management includes spatial planning that prioritizes economic, environmental, and social aspects. This includes:
- Regulations governing land conversion to prevent the loss of agricultural land and green areas
- Application of sustainable agricultural practices to protect existing agricultural land
- Cooperation between the government and the community in sustainable land management to ensure economic welfare and the sustainability of ecosystems
Conclusion
Changes in land cover in Medan City between 2000 and 2011 show a concerning trend, where agricultural land is decreasing and converted into residential land. This research confirms the importance of cooperation between the government and the community in sustainable land management to ensure economic welfare and the sustainability of ecosystems. With the right policy, it is expected that changes that occur can provide a balanced benefit between development and environmental preservation.
