    Role of Fertilisers for Climate-Resilient Agriculture
    (2017) Scott Angle; Upendra Singh; Christian O. Dimkpa; Deborah T. Hellums; Bindraban, Prem S.
    With the world’s population growing to nearly 10 billion by 2050, food production must increase by up to 70%. However, the future food supply depends on our ability to expand agricultural production whilst confronting climate change. Fertilisers drive agricultural intensification, feeding more than half the world’s population. Their use slows deforestation, a major source of greenhouse gases, and prevents land degradation and declining crop yields resulting from the depletion of soils’ nutrients, organic matter, and carbon. Despite these benefits, overuse of fertilisers leads to a number of negative environmental consequences, including eutrophication, ground water contamination, and soil acidity. Additionally, losses associated with nitrogen-based fertilisers are a major contributor to greenhouse gas emissions from agriculture. Both chemical and organic fertilisers impact upon the release of greenhouse gases into the atmosphere, increasing or decreasing emissions depending on how they are used. This study assesses their impact and analyses fertiliser management practices and products, such as enhanced efficiency fertilisers, balanced fertiliser formulations, and microbes (biofertilisation), that increase food production and mitigate climate change.

    The Role of Mineral Fertilizers in Climate-Resilient Agriculture: Focus on Myanmar
    (2018) Bindraban, Prem S.; Christian O. Dimkpa; Upendra Singh; Deborah T. Hellums
    The use of mineral fertilizers has permitted at least 50% of global food production. However, use of fertilizers could have negative environmental consequences contributing to climate change. Climate change is thought to be partly responsible for increases in abiotic and biotic perturbations that negatively impact crop production. Impacts of climate change, such as an increase in incidences of flooding. drought, salinity, and crop disease, are noted for Myanmar. However, appropriate use of existing nitrogen (N) fertilizers, development of new N fertilizers with improved uptake efficiency, and the balancing of fertilizer composition to include secondary and micronutrients can mitigate both the contribution of fertilizer to climate change and the impact of climate change in agriculture. This paper addresses the role of fertilizers in a changing climate where drought, salinity, pests, and incidences of diseases are heightened. Strategies to enhance fertilizer ase efficiency toward engendering a climate-resilient production system are discussed for rice, the predominant crop in Myanmar.
