The Director’s biography


The road to The HH-2 Horticultural System


Richard Higgins NDA. PDC. is Director and Founder of Sustainable Agriculture London and Director of Good Gardeners International. Richard was raised on a Somerset mixed farm in the UK and attained his NDA at the Royal Berkshire College of Agriculture. He later completed a ten year post graduate study, of the works of Sir Albert Howard while travelling and teaching from China to Hawaii. Howard is now considered the Grandfather of organic farming and his research from the Permanent Agriculture of the east (which is where the term Permaculture was derived), and the growing system that he employed, has formed the foundation of the Howard-Higgins system today.

Richard has become a world leading exponent of this branch of Sir Albert’s work on Soil Fertility and has developed the HH-2 Systems which render all types of organic wastes and obnoxious wastes, HH-3, into fertilizer in 90 days. Richard first trialled this work on a farm in Hertfordshire and was so astounded by the results that he went to India to trial the work again there; as Howard had done 100 years before.


Writing of The Lost Science of Organic Cultivation 1997

Richard completed this title in Calcutta, India, which is an update of Howard’s work

The Waste Products of Agriculture, Faber and Faber, 1931


HH-2 Horticultural system manufactured in the UK 2001


Haiti 2010

he spent three months at the Haiti earthquake disaster utilising the Howard-Higgins method of DRY sanitation and waste management – forming ‘the cleanest refugee camp in Haiti’ where he developed the first OXFAM urine separator footplate, which they now have in production. His site was recommended to be open to the public by the DINEPA WASH office and the site was visited and approved by the Technical Director of CRS., and many others including Professor Reid of WEDC., who, in his appraisal of the sanitation disaster in Port Au Prince Haiti, recommended that the HH-2 system was the most effective method of obnoxious waste management.

Mozambique 2012

Richard was deployed to Mozambique with The Royal Norwegian Society (NorgesVel) where trials were completed on scaling up the HH-2 system for maximum carbon sequestration from general farm wastes and local sanitation inputs. The system is known as Black Carbon Farming as this method sequesters 3 times more carbon than any above ground growth (Lawton, Permaculture Research Institute, Australia).


Soil Association Presentation 2012

Richard is also a consultant to various other groups on food security and presented at the National Soil Symposium, for the Soil Association. He runs a Micro-farm for teaching sustainable systems for the future.


Rothamsted Soil Scientists 2013

He was involved with the GM debate with Rothamsted Research and after presenting the case against GM technology on the Farming Today programme was subsequently invited to meet with the top five soil scientists of Rothamsted Research by Maurice Molony, the Director.


Radio 4 Farming Today 2013

More recently he has and at the National Badger conference in Hampshire about the prevention of TB in cattle through the introduction of the HH-2 system for sterilising cow waste and producing antibiotics in the soil that are passed into animal fodder.


Sweden 2013

Richard presented the science of the HH-2 system to the Swedish Environmental Institute in Stockholm, where the Director, Dr. Roasemarrin was so impressed that he suggested that ‘this science should be taught from football stadiums.’ Richard also presented to the subcommittee of SuSanA (3,000 members) where he is the co-chair of the working group WG05 – Sanitation to Agriculture.


3rd African Congress for Water and Sanitation 2013

Richard attended this congress in Kigali, funded by the Waterloo Foundation and made several approaches to the committee about the major different aspects to the Howard-Higgins system that is now manufactured in the United Kingdom.


Fertility Farming released 2014

with a review from Sir Julian Rose Richard released his second title which is now the Operators Manual which is distributed with the HH-2 Horticultural equipment. After hearing of the work of Professor Ted Cocking of Leeds University on the technology of introducing nitrogen fixing bacteria onto any crop root system Richard was invited to meet the CEO of Azotic Technologies at the Institute of Directors in London to discuss his soil amendment programme. He was then offered a possible world partnership combining the two technologies.


Rothamsted 2015

Attending a “Year of the Soil” lecture at Rothamsted Richard was subsequently invited to meet the new director of Rothamsted, Achim Doberman, who he hopes will take up the suggestion of the previous director Professor Maurice Moloney to ‘take this work to the Far East to obtain funding and carry out this work on a large scale.’


Oxford Real Farming Conference 2015

From the immense interest from his presentations to a packed auditorium at this conference Richard is now lecturing at Agricultural Colleges,


Easton and Ottley Agricultural College 2015

Dr. Anthony Wilson of the Eastern and Ottley Agricultural College invited Richard to teach a module on the Howard System to his Msc students for two consecutive years. Dr. Wilson believes this fundamental science is lacking in the agricultural institutions of today and has ordered the HH-2  system for the new greenhouse development at Askham Bryan College where he now works. Richard joined the UKTI recently and was invited to meet the Agricultural Representative for Pakistan through the British Foreign Office. He was informed that ‘the Government of Pakistan would be extremely interested in this technology.’


Kew Gardens 2016

After viewing a TV programme “Kew on a Plate” and seeing the large array of diseases and pests in the vegetable gardens of Kew Gardens in London, Richard offered to install his HH-2 system there. Their Mycology department have identified the specific fungi that Richard employs in his HH-2 system and have put him in touch with the CABI laboratory for further testing of the product.This however requires funding. Richard has received a donation to take up the offer made by HRH the Prince of Wales to attend his open invitation at the HighGrove Estate in Gloucestershire, UK, where he intends to deliver the Howard-Higgins System in person.


Chairman of Good Gardeners International 2016

After being a trustee for many years Richard was offered the chair of the GGI by the founder Ramsay-Shewell Cooper and David Wilkin the previous chairman.


Survey Eastern Uganda 2016

Richard was invited to survey a school in Jinja, Eastern Uganda for the purpose of installing the HH-2 equipment and growing system for this school. An appeal for this and other projects are now on the Charity Choice web site

Warwick University 2017

Richard was invited to present to the Field Scientists of the Life Sciences Dept., of Warwick University which has now amalgamated with Wellbourne Horticultural Research International where Richard visited many years before to meet with Professor Noble – head of the field laboratories. Professor Holub, of Warwick, is seeking funding to test the HH-2’s end product HH-4 on the Haricot Bean farms that he is connected with in Kenya.


NorgesVel  + Save the Children + Good Gardeners Intl, 2019

This year has seen Norgesvel form a partnership with Save the Children International to collaborate with the Good Gardeners to  establish three HH-2 sites of some proportion across Mozambique. There is currently a signed MOU for this partnership.


Hinduja Foundation, 2019

Two members of the Good Gardeners were invited to attend a meeting with the London office of the Hinduja Foundation. Their Director is arranging for us to meet with the Foundations heiress in 2020.


Other areas of interest: Rothamsted have spent 50 years on the aphid problem and have to date found no solution. Richard has also communicated with the following establishments; The Potato Council Oxford and Cambridge University Farm on airborne potato blight; Wellsbourne Research Centre on freeing tomatoes from all kinds of diseases. Warwick University on setting up further growing trials in Africa and Pershore Horticultural College in the United Kingdom.

Dorset BioSolutions, 2020

Three of the team were invited to attend the Good Gardeners demo site in Hertfordshire. They are collaborating with us and are adding our aerobic technology to fill gaps in and between their existing anaerobic installations.

University of York, 2020

Invited to visit a leading Professor in Environmental Sciences to discuss the remediation technology of the Good Gardeners for a collaboration in Ghana and possibly Kenya.
