    Implementation of the Abuja Declaration on Fertilizers for an African Green Revolution
    (2009-06-16) Maria Wanzala-Mlobela
    This presentation discusses the implementation of the Abuja Declaration on Fertilizers for an African Green Revolution, focusing on the efforts to address the fertilizer crisis in Africa. The report presents an overview of the progress made at the regional and country levels, particularly in areas like harmonization of legislation, regional procurement, fertilizer production, and intra-regional trade. It also highlights the challenges faced and provides recommendations for future actions, including the need for accurate data on fertilizer consumption, improved regulation, and the establishment of the African Fertilizer Financing Mechanism (AFFM). The report emphasizes the importance of promoting sustainable and market-friendly fertilizer practices to enhance agricultural productivity in Africa.

    Nanoscale Elements Suppress Plant Disease, Enhance Macronutrient Use Efficiency, and Increase Crop Yield
    (2019-05) Jason C. White; Wade H. Elmer; Jorge L. Gardea-Torresdey; Christian O. Dimkpa
    The primary goal is to use nanoscale elements as an amendment strategy to suppress crop disease, improve nutritional content, and enhance yield. Soil pathogens significantly limit agricultural production, reducing crop yield by 10-20% and resulting in billions of dollars in annual losses. This shortfall in food production will worsen with a changing climate and an increasing population. Nanotechnology can play a critical role in maximizing global food production and achieving food security. Current approaches have focused on nano-enabled conventional agrichemicals, nanosensors, and waste treatment strategies. However, little is known about the effects of nanoparticle (NP) elements on disease suppression, macronutrient uptake, and crop growth. For example, micronutrients are pivotal in disease resistance through activation of defense barrier production and by affecting the systemic acquired resistance pathway. Unfortunately, element availability in soil is limited and foliarly applied micronutrients are not translocated to roots. Although NP intra plant translocation has been reported, there is no information on whether enhanced translocation of NP elements can deter root or shoot pathogens. Based on preliminary data, our central hypothesis is that NP nutrients can be used to strategically suppress disease, improve nutritional status and enhance crop growth and yield.
