The challenges faced by agricultural innovation systems (A.I.S.) are complex to solve, however, the authors consider that understanding the processes of innovation and development (R&D), sustainability, use of information and communication technologies, training, and outreach, as the focus of discussion in this review, have great potential to close the gaps in the system; as well as exploring strategies, projects and best practices that dynamize the operation of the system. The objective of this article is to review the literature on A.I.S.A.

Participatory Guarantee Systems (PGS) and short organic supply chains have emerged as promising solutions for smallholder farmers to provide organic produce to nearby consumers.

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.
