DINAMIKA PENDUDUK DAN KONVERSI LAHAN PERTANIAN MENJADI LAHAN TERBANGUN DI KABUPATEN TANAH DATAR

Abstract

This study aims to determine the condition of population dynamics (2010-2015), the condition of conversion of agricultural land into built-up land (2010-2015) and formulate policy directives related to population dynamics and land sustainability in Tanah Datar District. This type of research is a combination research using mixed research methods (qualitative and quantitative). This research was conducted in Tanah Datar Regency.
