We identify and explore the potential opportunities and challenges for promoting and expanding small-scale aquaculture (SSA) as an additional income-generating activity for coastal communities in southern Chile. Based on a conceptual model of SSA adoption decisions, we conducted field key informant semistructured interviews with stakeholders in the Los Lagos region and in the regional capital city, Puerto Montt. We conducted a qualitative analysis of the interviews to identify potential resource users’ perceptions of current SSA opportunities. Interpreting the content analysis results through the lens of economic decisions in the conceptual model, we find that weak monitoring and enforcement, difficulties in adapting to new jobs, limited recent spatial planning, constraints on access to marine user rights, and insufficient market development for marine products are among the main obstacles to the adoption of SSA. The stakeholders view SSA as an opportunity to expand marine-based productive activities under the continuous decline in wild fisheries. SSA adoption is perceived as a gradual transition process that requires cultural capital and knowledge, given the lack of familiarity with management and the legal and economic aspects of aquaculture. In contrast to the concerns of potential SSA adopters, government stakeholders emphasize concern over the lack of definitions for SSA, norms, and regulations. We discuss how public policy to promote SSA in Chile could target the key concerns of potential SSA adopters.

The addition of organic compounds to fertilizers has shown positive effects on plant metabolism. This study aimed to evaluate the macronutrient accumulation and productivity of potato with the use of biofertilizer (BF) applied to the leaves. A 2×7 factorial plot with a plot subdivided in time and ten replications used two forms of fertilization: a chemical fertilizer with conventional NPK (nitrogen, phosphorus and potassium: control) and conventional fertilizer plus biofertilizers (BF); evaluations were performed 31, 41, 51, 61, 71, 81 and 91 days after planting (DAP) using the Jelly cultivar. The BF increased the maximum N, K, Ca and Mg accumulations in the leaves, especially N and K, with the period of greatest accumulation occurring between 62 and 66 DAP. The accumulations of N, P, K, Ca and Mg in the tubers accelerated from 71 DAP. At the end of the cycle (e.g., 91 DAP), the increases in the nutrient accumulations of N, P, K and Ca were between 30 and 64% higher for the BF application, the Mg accumulations doubled and the S accumulations exhibited no differences between the evaluation periods. For the leaves, the following decreasing sequence of maximum accumulation was observed: K>N>Ca>Mg>S>P. For the tubers, the following decreasing sequence was obtained: K>N>P>Ca>Mg>S. The use of biofertilizers caused higher productivity of tubers of greater caliber and soluble solids contents in the cv. Jelly potato tubers.

Successful policies seeking to promote rural entrepreneurship require a conceptual model consistent with the features of rural spaces and free of stereotypes of entrepreneurship as being only technologically sophisticated. The objective of this essay is, first, to argue that rural areas can be fertile ground for entrepreneurial activities in middle-income countries such as Chile and, second, to discuss policy options to achieve the goal of encouraging a more innovative entrepreneurship in rural areas. The scientific literature on entrepreneurship and the definitions, types and roles of entrepreneurship in development are reviewed. The literature on the location of entrepreneurship is summarized to understand the drivers of observed territorial differences in entrepreneurial activity. One conclusion is that rural areas face a (seemingly) adverse economic geography for entrepreneurship, although there is a recent tendency for amenities-led growth. We then present the geography of rural entrepreneurship in Chile. Contrary to conventional wisdom, the rates of entrepreneurship in Chilean rural areas are high, although presumably of a limited growth potential under current conditions. Nevertheless, this entrepreneurial base provides a stock of knowledge from which a greater sophistication could be reached, and we discuss potential policy approaches to stimulate more innovative rural entrepreneurship. In the case of Chile, available policy options are coherent with the recently enacted National Rural Development Policy. A systemic, amenity-based approach gives middle-income countries opportunities for the development of more innovative rural entrepreneurship through territorial policies that provide local public goods and improve living conditions.

The triple helix model (THM) studies the interactions between academia, industry, and government designed to promote entrepreneurship and innovation in a knowledge-based society. This paper shows how agricultural extension works through the THM for inclusive innovation to evaluate its effects on farmers. For this purpose, we analyze the case of Cultiva UChile, a technology transfer center led by the University of Chile that operated from 2016 to 2020 and that was financed by and in cooperation with public sector organizations. Cultiva UChile offered extension services to vegetable growers from the Chilean Central Valley. As our main sources of information, we used internal reports and surveys of 91 farmers who received Cultiva UChile extension services from 2019–2020. A qualitative study of this organization, the actors involved, and the operation and governance of the center and a quantitative analysis of the center’s direct effects adopting descriptive techniques and binary logistic regression were used. The results show strong interactions between actors as the basis of Cultiva UChile and its positive short-term direct effects regardless of farmers’ paths in terms of innovation, cooperation, and investment. These results lead us to conclude that extension services adopted under the THM can be appropriate means to promote inclusive innovation in agriculture.

Agricultural productivity has been the focus of intense scrutiny since the time of Adam Smith. In this article, we focus on agricultural productivity from two perspectives. First, we provide estimates of total factor productivity (TFP) growth for a panel of 79 countries over a period of approximately 60 years. Second, we investigated the potential determinants of productivity growth, which include infrastructure, macroeconomic variables, and variables related to climate change. We find that productivity varies greatly across countries, with leading countries showing annual agricultural productivity growth between 2% and 3%. In regards to productivity determinants, we find small within-country effects but significant between-country effects.

The multiple crises facing humanity at the onset of the Anthropocene are creating a moment in which agroecology acquires greater relevance as an alternative approach for meeting sustainable development goals and providing guidelines for the reconstruction of a post-COVID-19 agricultural system that is capable of minimizing future widespread disruptions of food supplies by pandemics and climate change by enhancing linkages between small-scale food production and local consumption. There are three main areas in which agroecology can be used in the development of a new post-COVID-19 agricultural system: revitalizing small farms, creating alternative animal production systems and enhancing urban agriculture. Focusing food and agricultural policies on agroecology as a main strategy for achieving autonomy and resilience can rapidly transform the ways in which we produce and consume food while addressing global challenges, including climate change, biodiversity loss, food insecurity, poverty, and deteriorating health.

Seven potential controversial topics in agroecology are presented and discussed from a European perspective comparing the position of Agroecology Europe (AEEU) obtained from an iterative, participatory approach with members and compared with published literature, including views from other parts of the world. The seven controversial topics as follows: i) use of agrochemicals; ii) small-scale and peasant farming versus larger farms; iii) technological innovations in agriculture and precision farming; iv) biotechnology and genetic engineering in agriculture; v) local and short food circuits; vi) social justice; vii) gender perspective. The analysis shows that there are diverse points of view related to geographical area and sociopolitical contexts. However, there are several convergences in the ambition to redesign farming and food systems, as a lever acting on several topics, and in considering agroecology with a holistic, participatory, multiactor approach for the needed transition.
