The International Livestock Research Institute (ILRI) works to improve food security and reduce poverty in developing countries through research for better and more sustainable use of livestock. ILRI is a CGIAR research centre - part of a global research partnership for a food-secure future.
The International Livestock Research Institute (ILRI) seeks to recruit a PhD graduate fellow to work on fate of antibiotic residues and antibiotic resistant bacteria in livestock manure and their effects on greenhouse gas emissions and nutrient cycling. The successful fellow will be co-hosted under ILRI’s One Health Research and Education Center for Africa (OHRECA) and Mazingira Center for Environmental Research and Education.
OHRECA seeks to improve the health of humans, animals and ecosystems through capacity building, strengthening of local, regional and global networks and provision of evidence-based policy advice on One Health in sub-Saharan Africa. The centre has four thematic areas: control of neglected tropical zoonotic diseases; emerging infectious diseases; food safety and informal markets; and prevention and control of antimicrobial resistance. https://www.ilri.org/research/facilities/one-health-centre
The Mazingira Centre is an environmental research and educational facility established by ILRI in Nairobi. Research at the Mazingira Centre focuses on understanding and managing the environmental footprint of livestock systems without hampering productivity. https://mazingira.ilri.org/
About the position
Imprudent use of antibiotics is increasing in livestock production systems in low- and middle-income countries, with potentially severe consequences for human, animal, and environmental health. However, little is known about the fate of antibiotic residues in livestock manure in smallholder farm settings under traditional manure management systems. Bacteria that are resistant to antibiotics can spread into and across the environment through livestock manure, posing a health hazard that needs to be addressed. In addition, livestock manure is a source of greenhouse gas (GHG) emissions that contribute to global warming. To achieve sustainable livestock development pathways in East Africa, it is important to understand the impact of livestock production on the environment (GHG emissions as well as animal and human health impacts).
Despite potentially negative aspects of livestock manure, it is an important resource for smallholder farmers. It can be used as crop fertilizer, thereby reducing the need for expensive synthetic fertilizer, and is beneficial for soil fertility and stability. Understanding if and how antibiotic residues and antibiotic-resistant bacteria affect nutrient cycling during manure storage and field application is critical. Because GHGs are formed during microbially-mediated processes, the presence of antibiotic residues and resistant organisms can influence the magnitude of GHG emissions and the fertilizer quality of the manure. Manure management practices that both reduce antibiotic resistance and GHG emissions and are practical for smallholder farmers are urgently needed to stop the spread of AMR and to mitigate climate change.
To address these research gaps, ILRI seeks to recruit a PhD graduate fellow to investigate how the presence of antibiotic residues and antibiotic resistant bacteria affect GHG emissions and nutrient cycling in manure in different livestock production systems in Kenya, and how manure management interventions can help to reduce both GHG emissions and antibiotic resistance. To answer these research questions, the candidate will conduct a series of lab and on-farm experiments. The gained knowledge will help to prioritize good livestock adaptation and mitigation options in relevant livestock systems and help to build capacity in decision support and planning in East Africa.
ILRI Program: The fellow will be associated with Animal and Human Health & Sustainable Livestock Systems Programs at ILRI.
ILRI fellowship project title: Fate of antibiotic residues and antibiotic resistant bacteria in livestock manure and their effects on greenhouse gas emissions and nutrient cycling.
Responsibilities of the fellow:
Minimum requirements for the ideal candidate
Location: ILRI, Nairobi, Kenya.
Duration: 3 years
Terms of appointment and benefits: This is a 3-year appointment subject to satisfactory performance. ILRI will offer a competitive stipend to cover living expenses in the project location, medical cover, and meet all research expenses. ILRI will also meet tuition fees at the fellow’s university of admission. The successful candidate will be supervised jointly by an ILRI scientist and the university/academic supervisor and will receive capacity development opportunities from ILRI.
