Green Extension is an umbrella term used to describe rural advisory services which support the scaling up of sustainable agriculture. This encompasses a range of methods to promote various types of content. What these approaches have in common is a process of socio-ecological learning, i.e., supporting farmers to analyse local problems and opportunities, and test alternative practices under local conditions.

Researchers at the University of Queensland have worked on research projects in the PNG Highlands since 2005. These projects were, and are, applied research to manage soil fertility in sweetpotato-based cropping systems in the Highlands. They were funded by the Australian Centre for International Agricultural Research. Our key collaborator was PNG’s National Agricultural Research Institute. Although the projects were in the field of Soil Science, specifically soil fertility management, our approach has always been multidisciplinary.

The Water Resources Department, Government of Maharashtra, responsible for building infrastructure and delivering water to farmers and other users, has so far created irrigation potential of about 5.3. million hectares and the current utilization is about 76%. About 5000 Water User Associations (WUAs) have been established to manage the water supply within their designated areas. However, the water use efficiency and productivity is adversely impacting the overall water security of the state.

The International Fund for Agricultural Development (IFAD) financed the second Cordillera Highland Agricultural Resource Management Project (CHARMP2), in areas where poverty is most severe among indigenous peoples in the highlands of the Cordillera Region in northern Philippines. The aim is to reduce poverty and improve the livelihoods of indigenous peoples living in farming communities in the mountainous project area. The indigenous peoples consist of many tribes whose main economic activity is agriculture.

In India, Farmer Producer Organizations (FPOs) are considered as the most preferred institutional mechanism for enhancing productivity and income of farmers. This is based on the resounding success of a few farmer collectives that have aggregated their produce to realise better incomes. However, when efforts were made to scale up this interesting model across the country, several challenges emerged.

Holding a vision of Lifestyle for Environment (LiFE), and with a target of net-zero carbon emission by 2070, India plans to usher in a green industrial and economic transition through a movement with an environmentally conscious lifestyle. One of the credible options for a continuous, predictable, accessible and cost-free green energy source is solar power. In the agricultural sector, one of the key innovations in promoting solar irrigation was the initiation of the world's first ever Solar Cooperative - Dhundi Solar Energy Producers' Cooperative Society (DSEPCS) - in Gujarat, India.
