    Integrating approaches to study land use change and hotspots of malaria transmission in rural Madagascar: an observational study by Benjamin L Rice, BS, Christopher D Golden, PhD, Hervet J Randriamady, MS, Nicholas J Arisco, BS, Daniel L Hartl, PhD

    Published 2018-05-01
    “…Genetic data, especially in the northeastern localities, were consistent with the presence of stable foci of high transmission in remote areas where the landscape is dominated by recent and ongoing conversion of forest to agricultural land, primarily for rice cultivation. Interpretation: Remote communities in Madagascar, communities at the frontier of the rapid ecological transformation that is happening globally, have a disproportionately higher malaria burden than regional and national averages. …”

    Increasing the Yield of Upland Rice in Idle Land Through Nutrient and Weed Management by Abbas, Hartinee

    Published 2006
    “…Recently,demand for high quality and fragrant rice has increased markedly due to affluent and health conscious consumers in Malaysia.Research on upland rice had been neglected because of low yield,despite the many good characteristics of upland rice,such as fragrance and long grains size.Furthermore,it has the advantage of cultivation on dry land without accumulation of water.Therefore,a large track of idle land in Malaysia can be developed for upland rice cultivation.This study involves the documentation of upland rice that produce high grain yield and the soil physico-chemical characteristics of idle land.A glasshouse experiment was conducted using Bukit Tuku soil (Aquic Kandiudult) and three selected upland rice varieties (Ageh, Kendinga and Strao) for determination of the optimum levels of N, P, and K fertilizer based on biomass and nutrient partitioning from the earlier survey. …”
