Diversities In Motion: Multifunctionality of Maize Production in Different Family Farming Systems in South and Central Mexico

Background: Maize agricultural policy in Mexico has focused on a monofunctional vision of maize as a basic commercial product, through a bimodal vision of production systems (commercial and subsistence). However, the evidence suggests that the challenge of thinking about the multifunctionality of this crop must be faced due to the complexity of its relationship within different strata of society, to more adequately reflect the diversity of systems based on maize, as well as their flexibility to respond to new challenges and opportunities, and to have better public policy designs. Objective: This work seeks to delve into the importance of the multifunctionality of maize within the context of different types of production units in Central and Southern Mexico, which represent families that make use of different production systems based on maize. This diversity is not a simple cultural curiosity, but rather reflects the complex use of maize cultivation as an economic and cultural mechanism that provides stability to Mexican families who depend on maize as their main crop. Methodology: To describe the multifunctionality of maize in Mexico, we adopted a qualitative approach through in-depth interviews with 51 maize producers from different types of production unit (PU) in the states of Oaxaca, Chiapas, Mexico, and Puebla. A study of production units (PU) typologies carried out with information from 16 states of the country was taken as a basis, where five types of PU were characterized according to their available resources, maize management, and their social characteristics. Results: It was found that: (1) there is a clearly distinguishable PU gradient (where, in addition to the existence of commercial and subsistence units, three others were identified, with direct implications for the design of public policy) that use maize with several purposes; (2) multifunctionality is associated with the diversity of uses and genetic materials that PUs have, and; (3) the variety of functions of maize changes according to the importance of maize in each type of unit and trough time. Implications: This work is positioned in favor of an expanded vision of the maize sector in Mexico instead of a dichotomous vision, where maize systems behave as a fluid continuum where the context of the PU’s affects their relationship with maize, and the way in which they use this crop to face social, climatic, and economic changes, as well as their preferences as consumers, traditions, and cultural identities. Conclusions: This complexity calls to thinking about a pluridiverse maize policy that understands the social complexity of this crop through the multifunctional support it offers to different types of UP’s based on maize systems, and how these differences require more sophisticated institutional approaches. Key words: multifunctionality of agriculture; maize; farm typologies; diversification of agricultural activities; diversity of maize-based systems

Black-tailed Godwits (<i>Limosa limosa</i>) in southern Iberia, habitat description and finding colour marked birds from 1 – 26 February 2022:Portugal (Sado, Tejo &amp; Algarve), Spain (Doñana &amp; Extremadura)

In this expedition from 1 to 26 February 2022 we visited the most important areas for Black-tailed Godwits in southern Spain and Portugal during northward migration. Our aim was to resight individual colour marked birds, describe the habitats godwits used and to gain information on threats and opportunities by field observations and meetings with local experts. In this report we present a daily overview of our findings with photos, locations we visited, numbers present and the first conclusions and recommendations

Immediate impact of COVID-19 pandemic on farming systems in Central America and Mexico

In this article we present a first attempt to understand the immediate impact of COVID-19 and the sanitary measures taken by governments on farming systems in Central America and Mexico (CAM). Through a review of information generated in these initial months of the COVID-19 pandemic (webinars, blogs, electronic publications, media) and 44 interviews with key informants across the region, we have identified the main impacts felt by different types of farming systems in the region. The results presented focus only in the immediate effect of COVID-19 pandemic and the mechanisms implemented by farmers in the first months. Whether these impacts and response mechanisms will result in a transformation of the farming systems towards greater resilience and sustainability is still an open question

Conservation Agriculture Benefits Indian Farmers, but Technology Targeting Needed for Greater Impacts

Rice and wheat production in the intensive, irrigated farming systems of the Indo-Gangetic Plains (IGP) is associated with significant negative environmental and health externalities. Conservation Agriculture (CA) has the potential to curb some of these externalities while enhancing farm income. However, farmer adoption of CA remains modest in the Indian IGP. The present study focuses on the constraints to adopting the major CA component, zero tillage (ZT). We examine whether ZT wheat is feasible for smallholders and the potential of technology targeting to realize faster and wider diffusion. Econometric models and machine learning algorithms were used to analyze remote sensing data and farm household data collected from the Indian states of Punjab and Bihar, two contrasting agrarian economies of the IGP. While farmer adoption was low among smallholders (owning <2 ha of land), the on-farm effects of ZT on variable cost reduction and yield and profit enhancement for smallholders are comparable to large farmers. We estimate the economic potential of technology targeting using an equilibrium displacement model. In the relatively developed state of Punjab, technology targeting based on landholding size does not appear to add substantive economic benefits. In Bihar, a less prosperous state with a dominance of smallholders in the population, technology targeting could markedly enhance economic surplus and reduce rural poverty
