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.

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.

This research delves into the underlying impacts of farmers' innovative entrepreneurship on agricultural and rural economic development in China, adopting a dynamic and spatio-temporal perspective. The study utilizes panel data encompassing 30 provinces (cities and autonomous regions) from 2015 to 2020, with a systematic consideration of diversified spatial weight matrices.

In rural areas of developing countries, more than 70% of the population still depends on agriculture. However, economic crises, unscientific land allocation and climate change issues have hindered attempted gains in agricultural productivity and related rural development outcomes. Technology-driven breakthrough has usually pushed agriculture to the brink of another development that can affect not only plant diversity and yield, but also climatological and socio-economic outcomes.

The overarching research question developed in the Conceptual Framework conveys the core objective of SALSA (What is the contribution of small farms and of the related food businesses to sustainable FNS in a wide range of foos systems?) by highlighting that the research follows a systemic approach.

The SALSA project aims at assessing the current and future role of small farms and related small food businesses in contributing to sustainable food and nutrition security at regional level in Europe and in selected African regions, and to identify the conditions for them to meet the demand for food in an increasingly populated and resource-constrained world.

In the SALSA project, transdisciplinarity means a process of integration of knowledge between researchers belonging to different disciplines (in our case, sociology, economics, anthropology, geography) and with non-academic actors such as NGOs members, innovation brokers, policy makers). The role of transdisciplinary theory building within SALSA is to link diverse areas of knowledge through a co-constructed conceptual framework in order to underpin effective action towards improved FNS.

The project Small Farms, Small Food Business and Sustainable Food Security (SALSA) intends to assess the role of small farms and small food business in terms of food production and food security. One important first step in doing this is to test and develop methods and tools able to produce accurate and useful information about small farms.
