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.

Participatory Guarantee Systems (PGS) and short organic supply chains have emerged as promising solutions for smallholder farmers to provide organic produce to nearby consumers. PGS is an institutional innovation that builds trust among producers, traders and consumers through a low-cost transparent and participatory certification mechanism. They have particularly gained a foothold among smallholder farmers in middle- income countries, where third-party certification costs are often unaffordable.

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.

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.

Colombia produces more sugar per month on one hectare of land than any other country. This privilege is due to the productivity of sugar cane grown in the Cauca River valley, where 14 processing plants operate nearly year-round to produce sugar, honey, bioethanol, and electrical energy. The cane is supplied by 2750 growers, owners of 75 percent of the 240 000 hecatres planted, and by the sugar mills themselves (25 percent of the area). The sugar cane chain provides more than 286 000 direct and indirect jobs.

Mexico is considered the geographic center of origin of the Agave genus. The "maquey pulquero" (Agave mapisaga and A. salmiana) is produced and used in central mexico to make a traditional fermented beverage known as pulque, which has been made and consumed since pre-Hispanic times and is still a form of subsistence for rural families.

Food and Nutritional Security (FNS), understood as the availability and access to quality food, is fundamental for human development. The sustainability and progress of the agricultural sector are essential to maintain a food supply in quantity and quality. In the department of Córdoba, multidimensional poverty is twice as high for rural areas (51.9 percent) as compared to urban areas (23.3 percent). Thus, rural producers' role in boosting the local economy, contributing to generating jobs and FNS is essential.
