Biodata - Denis Alder


Denis Alder was born in England and attended Tonbridge School, Kent, before moving to Australia in 1967. He gained a 1st class Honours degree in Forest Science from the Australian National University, Canberra in 1973. From 1974 he worked at the University of Oxford doing research on growth models of forest ecosystems, for which he was awarded a D.Phil. in 1978. From 1979 to 1983 he worked in various capacities for FAO, writing manuals on statistical methods and growth modelling in Rome and Oxford, and undertaking biometrics and field survey work in Ghana.
 

From mid-1983 to 1989 he worked as a technical specialist on statistical techniques, survey work and monitoring and evaluation for the World Bank on projects in Turkey and Ghana. From 1989 he became a freelance consultant working on short-term assignments with several international organizations (see Clients). This work was primarily concentrated on statistical design, analysis of survey data, particularly for long-term ecosystem monitoring, modelling ecosystem dynamics, biomass and other allometric equations, carbon sequestration modelling, and systems for regulation and monitoring renewable natural resource management.
 

These assignments involved work on the ground in a number of countries, including Australia, Belize, Botswana, Brazil, Cameroon, Costa Rica, Ecuador, Ghana, Guyana, Indonesia, Ivory Coast, Kenya, Mexico, Papua New Guinea, Sudan, and Uganda.
 

From 2004 to 2017 he consulted for the Agriculture and Horticulture Development Board, developing survey designs for capture of data on prices, yields, crop areas, developing and maintaining a website (growerpanel.ahdb.org.uk) for data entry by field contractors, growers and purchasers, which also provides live statistics on crop yields, areas, and prices.
 

During this period he continued to do international consulting, in particular in Guyana, in Brazil with EMBRAPA Amazonia Oriental, and with the Federal University of Acre, developing systems and teaching courses for forest ecostystem management, surveys and predictive modelling. He also consulted for the European Space Agency (ESA), developing a QGIS-based analytical toolkit, and for Ajiko in Japan also on a QGIS Python plugin-in for modelling of land use change. He has also developed a family of models of carbon dynamics in plantation ecosystems for VCS investment analysis.
 

Most recently he has joined Valid International in a role focussed on survey design and analysis relative to nutrition, health, water and sanitation, poverty and related indicators.
