Lately, the Hill Pond Rice System (HPRS) is being promoted as a form of alternative farming systems in selected northern provinces of Thailand, in which the land conversion is designed to maximize rainwater harvesting in farmland consisting of forest trees, water reservoirs, paddy fields, and high-value crop cultivation to serve environmental and livelihood needs. This study employed the double-hurdle model and the tobit technique to investigate the farm-level factors associated with land conversion from maize monocropping to the HPRS using primary data collected from 253 households in Nan, Chiang Mai, Tak, and Lampang Provinces. It was found that education, farming knowledge, understanding benefits of the HPRS, access to water sources, access to advis, and workforce sharing raised the likelihood and extent of farmland conversion into the HPRS. In contrast, perceived complexity of the HPRS, experiences with negative shocks, and land tenure security lowered the likelihood and extent of land conversion. The findings suggest that on-farm collective action should be promoted to mitigate labor constraints in implementation and that access to equipment should be enhanced through HPRS advisors’ visits.

Loss of natural habitat is one of the major threats for biodiversity worldwide. Habitat conversion not only changes diversity and species composition locally (alpha diversity) but might also lead to large-scale homogenization of species communities and decrease in regional species richness (gamma diversity). We investigated the effect of farmland conversion on amphibian communities in Rwanda and compared local and regional (country-wide) taxonomic, functional and phylogenetic diversity between natural and farmland sites (agricultural marais). Alpha diversity was higher in the disturbed farmland than in natural sites. However, species turnover among farmland sites was much lower than among natural sites, resulting in highly homogenized amphibian communities and much lower country-wide taxonomic, functional and phylogenetic gamma diversity in farmland compared to natural sites. The few frog species found in farmland were mostly disturbance-tolerant species that are widespread in Eastern Africa and beyond. In contrast, most of the regionally endemic frog species that make this region a continent-scale hotspot of amphibian diversity were found only in the natural habitats. Ongoing farmland conversion might lead to a loss of regional endemism and a widespread homogenization of species communities across sub-Saharan Africa.

Malang Municipality, the second-largest municipality in East Java Province, has a role as an education and business growth pole. The increasing housing and public service demands in the area correspond with the population growth. It then triggers agricultural conversion, which is predicted to be fully converted in 2024 without any control measurement. Therefore, farm owners have an essential role in agricultural land use. The present study aimed to identify the factors that affect farm owners’ decisions in converting their lands. This study employed correlation analysis to determine the factors influencing the degree of intention to convert farmers’ farmland to settlement. This present study addressed farmland conversion intention, socio-economic factors of farm owner, land use condition, and spatial regulation based on farm owners’ perception. The results showed that the degree of farmland conversion corresponded with the importance of the variable to land conversion. This study demonstrated that farm owners’ perceptions were important and had an essential role in farmland conversion. Moreover, the upcoming regulation should address farm owners’ perception along with tangible variables, such as total income.
