Oscar started his professional life as a marine biologist and later became an economist. His research interests centre on the application of economics and biology (bioeconomics) to tackle problems of sustainability in agriculture and natural resources. His recent work has been in two major areas: the role of carbon markets to address climate change and the economics of biosecurity to protect native ecosystems.
Oscar has been a member of a Technical Advisory Group on Control of Invasive Species in the Galapagos Islands and a visiting expert at the Food and Agricultural Organisation of the United Nations (FAO) in Rome. He has applied his interdisciplinary expertise to address a variety of problems in nature conservation, fisheries, aquaculture, grazing systems, invasive species management, climate policy and sustainable agriculture both in Australia and internationally.

Clinical Skills and Experience
Oscar’s consultancy activities are aligned with his research interests. They have focused on practical approaches to interdisciplinary problems.
Weed Eradication Feasibility Analysis by Oscar Cacho and Paul Pheloung
This program is written in Visual Basic for Applications and runs within MS Excel. The model combines population dynamics and search theory to calculate the probability that a weed invasion will be eradicated based on the amount of time invested in searching for it (search effort).
This is work in progress. It is envisaged that the software will continue to evolve as it is tested by experts and feedback is received. The original concept for this software was developed by Paul Pheloung (from the Australian Department of Agriculture Fisheries and Forestry) in connection with a project on the Galapagos Islands. The software evolved through the incorporation of search theory and matrix population models.
