  • Conservation agriculture for food security in Cambodia
    Boulakia, Stephane; Chabierski, Stephane; Hok, Lyda; Kou, P.; Reyes, Manuel R. (2012)
    This presentation reports on work that a SANREM innovation lab research team has conducted in Cambodia. The study sought to: (i.) identify field-and-farm-level conservation agriculture production systems that will minimize smallholder costs and risks while maximizing benefits and (ii) adoption and measure crop yield and biomass from conservation agriculture production systems, and compare them with conventional plow-based systems

    Conservation Agriculture for Food Security in Cambodia and the Philippines
    Boulakia, Stephane; Hok, Lyda; Phally, K.; Reyes, Manuel R.; Mercado, Agustin R. Jr.; Ella, Victor B.; Edralin, Don Immanuel A. (Greensboro, NC: North Carolina A&T State University, 2012)
    Degraded landscapes are expanding annually in Southeast Asia. Rural poverty in upland communities increases pressure on natural resources like forest, soil and water . These are the last “capital” for the poor and they are rapidly diminishing due to non-sustainable management. Such practices reduce agricultural productivity, which in turn heightens food insecurity and exacerbates poverty.

    Conservation agriculture in urban deserts
    Edralin, Don Immanuel A.; Hok, Lyda; LeNgoc, K.; Williams, Mark A.; Gayle, G.; Raczkowski, Charles W.; Reyes, Manuel R. (2012)
    Limited access to nutritious and affordable food is experienced by 23 million people in the US as they live in 'food desserts' making them food and health insecure. Resources such as land, water, labor and capital are used not in the context of sustainability making the problem more severe. Urban conservation agriculture will be an ‘oasis’ or a sustainable solution to this problem on food desserts and unsustainable resource use. A part of a human disturbed landscape, a turf grass lawn, was converted into ‘oasis sofas’, a 3’ by 6’ vegetable production area outlined by wood, following conservation agriculture principles of minimum soil disturbance, continuous mulch and diverse species at North Carolina Agricultural and Technical State University. Rainwater was used for irrigation and leguminous cover crops used to increase soil fertility. The cost of maintaining oasis sofas’ were seen to be lower than maintaining an equal amount of turf lawn. Oasis sofas’ adds beauty and diversity to the lawn while it gives nutritious food to the household. Fall yield of unfertilized vegetables; broccoli, collard greens, kale and lettuce were 4.5, 2.8, 1.7 and 2.6 kilograms, respectively, per ‘oasis sofa’. Part of the capital and hired labor to maintain turf grass lawns may be used to maintain oasis sofa’s which would lead to greater benefits as it brings nutritious food to the household. Oasis sofas ease access to homegrown healthy food which would likely improve the household’s food and health security.

    The Oasissofa: Application of conservation agriculture in urban vegetable production
    Edralin, Don Immanuel A.; Hok, Lyda; Le, K.; Williams, Mark A.; Reyes, Manuel R. (2012)
    The implementation of urban conservation agriculture can serve as an alternative to a lawn that addresses the problem of urban food deserts. This powerpoint summarizes the formation of ‘oasis sofas,’ conservation agriculture vegetable beds 6’ by 3’ in size, at various public schools in North Carolina. Their objective for the study was to show the benefits of Oasis sofas in providing nutritious pesticide free healthy food and for urban conservation agriculture research, instruction and extension.
