SECONDARY FORESTS IN SWIDDEN AGRICULTURE IN THE HIGHLANDS OF THAILAND

Swidden farming is the main agent of conversion of primary forests to secondary forests in the highlands of mainland Southeast Asia, but there is a deterioration and decline of the practice with land use intensification.

520			\|a Swidden farming is the main agent of conversion of primary forests to secondary forests in the highlands of mainland Southeast Asia, but there is a deterioration and decline of the practice with land use intensification. The population growth in northern Thailand has forced lowland farmers practising permanent wet rice cultivation to turn to short-rotation swidden in the foot-hill zone. Highland swidden agriculturists are adopting more intensive forms of swidden or are shifting to permanent farming. This change is supported by road construction and increased marketing opportunities for temperate crops grown in the highlands. The decline of swidden farming is causing a net degradation and decrease in fallow-related secondary forest cover, with consequent losses in the biodiversity and economic potential of these forests. There exists no policy or legal framework in Thailand that allows for the preservation and sustainable legal use of these forests. Major obstacles for the development of such a framework are the prevailing assessment of secondary vegetation as degraded scrub, and a highland development policy that does not encourage forest use by local communities. The introduction of community forestry legislation is still pending. There is a need to design land use systems that integrate fallow forest management with agricultural production. Pertanian ladang merupakan agen utama penukaran hutan primer kepada hutan sekunder di tanah tinggi Asia Tenggara, tetapi amalan tersebut berkurangan kerana wujudnya penggunaan tanah secara intensif. Pertumbuhan penduduk di utara Thailand memaksa petani-petani tanah pamah yang mengamalkan penuaian padi sawah bertukar kepada pertanian ladang kitaran pendek di zon kaki bukit. Para petani pertanian ladang tanah tinggi menggunakan kaedah pertanian ladang yang lebih intensif ataupun beralih kepada pertanian kekal. Pengalihan ini disokong pula dengan pembinaan jalan dan peningkatan peluang pemasaran bagi tanaman iklim sederhana di tanah tinggi. Kemerosotan pertanian ladang menyebabkan pendegradan bersih dan pengurangan litupan hutan sekunder yang berkaitan bekas ladang, dengan kehilangan secara langsung biodiversiti dan potensi ekonomi hutan ini. Tidak terdapat polisi atau rangka kerja undang-undang di Thailand yang membenarkan pemeliharaan dan pengekalan penggunaan hutan ini. Halangan utama perkembangan rangka kerja tersebut ialah penilaian tanaman sekunder sebagai semak samun usang, dan polisi pembangunan tanah tinggi yang tidak menggalakkan penggunaan hutan oleh penduduk tempatan. Undang-undang perhutanan penduduk masih belum dikemukakan. Terdapat keperluan bagi mewujudkan satu sistem penggunaan tanah yang menggabungkan pengurusan hutan tanah bekas ladang dengan pengeluaran pertanian.
