John Hodgson

Professor in Agronomy at Massey University, 1986 – 2002; Fellow of the Royal Society of New Zealand 1998 – 2018, International Statesman of Pasture and Rangeland Science.

John lost a long battle with Parkinson’s disease in October 2018. He is survived by his wife Ruth (who through her support to John made a large contribution in her own right) and their five children. At Massey University he will be remembered first and foremost by his many PhD and Masters students who appreciated his perspicacity, as evidenced by his uncanny ability to decompose complex research topics into their key research questions, and his rapid return of any written material with hugely insightful comments. However, his outstanding performance in the supervision of his graduate students was only a small part of John’s career contribution. As will be outlined below, his scientific achievements in the UK before accepting his professorship at Massey University earned him a DSc degree from University of Leeds in 1987, and saw him recognised as a go-to person for book chapters targeting international audiences in his field. John’s international recognition in the UK readily transposed to New Zealand, and in his role as Professor at Massey University he displayed science leadership both within New Zealand and beyond, with China and South America among the countries or regions where his ideas and contribution had a profound influence.

Early years and education

John grew up on a mixed-livestock farm near the village of Askrigg in Wensleydale, Yorkshire. His father, Dick Hodgson, was both a farmer and local magistrate. His mother was a teacher of languages before her marriage. John was the eldest of 4 children. The science in his upbringing is revealed by the dedication of his 1990 textbook to his father as the one ‘who used to pose the questions’ that he spent his career answering. John graduated with BSc (1st Class Honours) in Animal Husbandry from the University of Leeds in 1960. While studying at Leeds he met Ruth, a student at a nearby teacher training college. The couple were married in August 1960 after John’s graduation, and John then took up a position as a Scientific Officer at the Grassland Research Institute (GRI), Hurley, where Professor C.S. (later Sir Colin) Spedding had a strong influence on his career development.

The United Kingdom Years

John left the GRI, Hurley, in 1963 to take up a lectureship in Animal Husbandry in the Department of Agriculture at Leeds University. John received his PhD, entitled ‘A study of some factors affecting the solid food intake of calves’, from Leeds University in 1968. Following award of his PhD, John returned to the GRI where he was Principal Scientific Officer (1969–1974), and held positions as Deputy Head, and Head of Grazing Ecology. In this period at Hurley, he took on his first PhD students: Jorge Rodrigues and Jorge Combellas from Venezuela, and Rafael de Lucia, from Uruguay. From 1981 to 1986, he held the position of Head of the Grazing Ecology Department at the Hill Farming Research Institute (HFRI) in Penicuik, Scotland. This latter position allowed John to cement his United Kingdom network of professional contacts while also supervising further international PhD students, among these Julio Arosteguy from Argentina, and John Bircham from New Zealand. With PhD students came travel to their home countries to better understand the context in which they would conduct their professional work. Countries visited between 1970 and 1976 included Peru, Venezuela, Argentina, and Chile. From Penicuik, John also took a year’s sabbatical at then DSIR Grasslands, Palmerston North. These years set the foundation for John’s unique international perspective on grasslands, grazing processes, and grazing behaviour research. Titles of publications from this era (see below) are informative; firstly, for the diversity of topics investigated (ranging from various aspects of calf nutrition, through defoliation frequency of individual tillers in a set stocked sward, to the relationships between herbage mass, animal bite dynamics, and herbage intake and animal performance); secondly, for the identity of co-authors, including among others, J. A. Milne, S. A. Grant and T. J. Maxwell; and thirdly, for the importance of the work, one example being a lead editor role in production of the British Grassland Society ‘Sward Measurement Handbook’ co-edited with R. D. Baker, Alison Davies , J. D. Leaver, and A. S. Laidlaw.  The publications show that John was both informed by colleagues in related disciplines and in exchange caused them to ask relevant questions and become collaborators; few scientists achieve this. John in this stage of his career displayed a penchant for devising mechanistic investigations of the science behind the various components of a grazing system from rumen function, through drivers of herbage selection by animals, to reciprocal impacts of the animals on sward dynamics and sward quality on animal behaviour. His investigations evolved over time in a way that built complexity of system component definition and integration of understanding across system processes. Behind all of that there was the sharpness of mind that would allow him to read a work, grasp its message, and see the key issues, much faster than others.

The Massey University Years

Department Administration

John brought to Massey University strong administration skills developed in his years at the GRI, Hurley, and the HFRI, Penicuik. The Agronomy Department at Massey University, when John arrived in 1986, embraced pasture and crop science, weed science, plant breeding and agricultural machinery and together with Departments of Soil Science, Horticultural Science, Plant Pathology, Animal Science and Farm Management in the Faculty of Agricultural and Horticultural Sciences supported the delivery of Bachelor of Agricultural Science and Bachelor of Agriculture degree programmes. John instinctively understood the governance processes at various levels and provided his staff with sound leadership and oversight of their career development. The years of John’s tenure spanned the ‘user pays’ philosophy and the ‘sunset industry’ view of agriculture of successive governments in the 1980s and early 1990s. As a result, John presided over a period of unprecedented organisational repositioning. By the time of his retirement in 2002, former Departments of Agronomy, Horticultural Science, Soil Science, and Farm Management, had merged into the Institute of Natural Resources (INR) within the College of Sciences (which in turn incorporated former Science and Agricultural and Horticultural Science Faculties), supporting delivery of a new degree, the Bachelor of Applied Science, and also providing some BSc courses. As the changes unfolded, John perceived he was faced with a choice between continuing as an active researcher or full-time administration of the larger Institute formed by the merged Departments. He chose to continue as an active researcher, retaining leadership of the Pasture Science Group within INR, actively supporting his graduate students, maintaining his international scholarship (including a notable collaboration with Gilles Lemaire of the French Research organisation I.N.R.A.), and showing future vision by establishing a virtual School for the Environment within the College of Sciences.

Graduate students

There is no doubt John enjoyed the thinking process integral to the support of his graduate students, journeying with them and providing a sounding board for their discoveries and decisions. He understood that successful research needed resources which he would work to provide, and his quick mind provided for insightful feedback, making him a sought-after supervisor. Ruth was active in support of students’ families, including provision of English language classes. There were at least 30 graduate students supervised or co-supervised by John while at Massey, with Iran, China, Mexico, Brazil, Argentina, Paraguay, Uruguay, and Chile among the countries represented. The research topics, as indicated by the publication record below, also covered a wide range demonstrating John’s passion to develop an understanding of grazing systems that embraced detailed knowledge of each of the system components, from dynamics of sward tiller and leaf production, through to drivers of animal intake and performance.

China

John made his first trip to China in 1986, when he was invited by Professor Tingcheng Zhu to Changchun, to participate in the International Symposium on Grassland in Forest Areas held at Northeast Normal University.  From that point John maintained close ties with China, until his last visit there in 1996.

John’s contribution to Chinese grassland science had two main thrusts. The first was the introduction of principles of grassland management and grazing theory from the UK and New Zealand.  This was primarily achieved through a collaboration with Professor Jizhou Ren, head of the Gansu Grassland Ecological Research Institute (GGERI, Now College of Pastoral Agriculture Science and Technology (CPAST), Lanzhou University). John was introduced to GGERI through Zhibiao Nan, who was studying for his doctoral degree at Massey University at that time.  Together with a Massey colleague, Dr Alex Cheongping Chu, John Hodgson and Professor Ren secured project funding jointly from the United Nations Development Programme and the New Zealand Government, for pasture farming technology transfer from New Zealand to China. The project was based in Guizhou province and ran for 6 years, with a focus on training of Chinese extension staff, both through visits to New Zealand and coursework delivered by Massey University staff in China. Some 20 Chinese staff participated and the resulting development of grassland science in Guizhou was such that the province was regarded in China as showing domestic leadership at that time. A second achievement of note was the establishment of an MOU between Massey University and Beijing Agricultural University (now China Agricultural University). According to the agreement, Massey University was to provide doctoral or postdoctoral places for Beijing Agricultural University staff each year. Through this arrangement, Jingxin Xia and Fuyuan Liu gained their PhDs under John’s supervision at Massey University. In the course of these activities, John visited China many times to participate in academic conferences and give seminars and local project advice, thus making a significant contribution to the development of grassland science in China. Professor Zhibiao Nan, Dean Emeritus of CPAST and successor to Jizhou Ren remarked in providing this account of John’s professional contribution in China, ’Chinese grassland scientists will miss Professor Hodgson forever.’

South America

John’s professional reputation in South America was not an accidental convergence of professional availability and local opportunity. It was built on the recognition by his former students of his professional skills, and the recognition within the various organisations they worked for, that training under John’s guidance had provided a strong foundation. John worked with funding organisations to create mutual benefit to overseas organisations sending students, and to Massey. One of his trade marks was to turn funding for two-year Masters studies into three-year PhD scholarships by arranging for one year of the research to be carried out in the student’s home country as part of their employment. This philosophy created enduring relationships. Such was the respect for John in Latin America, that in 2010, 8 years after his retirement from Massey University, a valedictory conference with a 300-page proceedings and funding support from research providers in South America, was organised in Tandil, Argentina, by his former students, to celebrate his career contribution in the region and internationally.

International Grassland congress

John’s scientific statesmanship at an international level was well demonstrated in his contribution to the International Grassland Congress (IGC) movement. These quadrennial meetings have been a strong attraction for grassland scientists from their inception in the 1920s (with a first congress in Germany in 1927), through to the present day. The 17^th International Congress was held in New Zealand and Australia during 1993. This international meeting was 6 years in the making. John chaired the Organising Committee throughout that period and did a splendid job in balancing the views and demands of some very strong-minded individuals. In addition to his stewardship, John’s international reputation and networks were very important in attracting leading grassland and rangeland researchers from around the world to produce key papers and participate in debate and resolutions. This was a very successful Congress with approximately 2000 attendees. John’s level headed and rational approach to discussion and decision-making will be remembered. John remained a member of the IGC Continuing Committee until the 1997 meeting in Canada and played a significant support role for the 2001 IGC in Brazil, and over the following decade.
