Plants, Pathogens, and the Politics of Care: Xylella fastidiosa and the Intra-active Breakdown of Mallorca’s Almond Ecology

Almonds were once “the gold of Mallorca,” a source of modest wealth and a pillar of diversified farming systems for smallholders on the largest of Spain’s Balearic Islands. Now researchers believe nearly every rainfed almond tree on the island will be dead within as few as five years. The introduced bacteria Xylella fastidiosa, enabled by its spittle-bug vector, and emboldened by climate change, has flooded the xylem of these rainfed trees, impeding the flow of fluid and nutrients to the point where the tree can no longer survive. This article enrolls feminist theorizations of care and agential realism to broaden the political scope and stakes of a plant epidemic. I argue that by attending to the care relations underlying pathogenicity we can shift from narratives of landscape purification toward a more-than-human politics of care. Abstracto Una vez las almendras eran “el oro de Mallorca,” una fuente de riqueza modesta y un pilar de un sistema de agricultura diversificada para los payeses (campesinos) de la isla más grande del archipiélago balear de España. Actualmente los investigadores creen que casi todos los almendros de la isla pueden morir dentro de cinco años. Una bacteria introducida,Xylella fastidiosa, apoyada por su insecto vector, el salivazo, y animada por el cambio climático, ha inundado la xilema de los almendros de secano, impidiendo la circulación de fluidos y nutrientes hasta el punto de que el árbol no puede sobrevivir. Este artículo emplea teorizaciones feministas del cuidado y del realismo agencial para ampliar el alcance político de una epidemia de plantas. Argumento que teniendo en cuenta las relaciones de cuidado subyacentes de la patogenicidad, podemos pasar de los temas de purificación del paisaje a una política más-que-humano del cuidado.

A global database of diversified farming effects on biodiversity and yield

With the Convention on Biological Diversity conference (COP15), United Nations Climate Change Conference (COP26), and United Nations Food Systems Summit, 2021 is a pivotal year for transitioning towards sustainable food systems. Diversified farming systems are key to more sustainable food production. Here we present a global dataset documenting outcomes of diversified farming practices for biodiversity and yields compiled following best standards for systematic review of primary studies and specifically designed for use in meta-analysis. The dataset includes 4076 comparisons of biodiversity outcomes and 1214 of yield in diversified farming systems compared to one of two reference systems. It contains evidence from 48 countries of effects on species from 33 taxonomic orders (spanning insects, plants, birds, mammals, eukaryotes, annelids, fungi, and bacteria) of diversified farming systems producing annual or perennial crops across 12 commodity groups. The dataset presented provides a resource for researchers and practitioners to easily access information on where diversified farming systems effectively contribute to biodiversity and food production outcomes.

Crop Diversification for Improved Weed Management: A Review

Weeds are among the major constraints to any crop production system, reducing productivity and profitability. Herbicides are among the most effective methods to control weeds, and reliance on herbicides for weed control has increased significantly with the advent of herbicide-resistant crops. Unfortunately, over-reliance on herbicides leads to environmental-health issues and herbicide-resistant weeds, causing human health and ecological concerns. Crop diversification can help manage weeds sustainably in major crop production systems. It acts as an organizing principle under which technological innovations and ecological insights can be combined to manage weeds sustainably. Diversified cropping can be defined as the conscious inclusion of functional biodiversity at temporal and/or spatial levels to improve the productivity and stability of ecosystem services. Crop diversification helps to reduce weed density by negatively impacting weed seed germination and weed growth. Additionally, diversified farming systems are more resilient to climate change than monoculture systems and provide better crop yield. However, there are a few challenges to adopting a diversified cropping system, ranging from technology innovations, government policies, farm-level decisions, climate change, and market conditions. In this review, we discuss how crop diversification supports sustainable weed management, the challenges associated with it, and the future of weed management with respect to the diversification concept.

The Indian Antelope Nilgai (Boselaphus tragocamelus) Appropriate Contender for Domestication could add in Human Society

The domestication of animals was part of a major transformation in the way of life of an increasing number of human societies with deep social and spiritual changes. In the present study, we report about utility of Nilgai and the values of its products and how it can add variety in our diet. Domestication of Nilgai may prove as an outstanding diet (veal and juveniles) for human and domesticated carnivores it may be the most important achievements that man-made in his cultural history. It is very useful and has many kinds of beneficial mutualism with man exists. We also prerequisite to reconnoiter biological functions, importance, and distinctiveness of products viz milk, meat, leather and body parts such as skin, teeth, nail and other product in addition to transportation and export, because of their size and powerful appearance. The meat of Nilgai is said to be lighter and milder flavored than that of blackbuck meat. A domesticated animal such as livestock plays a vital role in diversified farming systems because food and recycling of nutrients through the farm are well proven. Nilgai appears to have different color which occurs during the developmental stage, like a fawn, juveniles and adults. Few Nilgai showed some docility behavior in nature subsequently that sighs of taming towards domestication. Nilgai may prove a higher status than other domestic animals when it comes to success in domestication. The Nilgai dwelling near the human habitation in proximity to a close distance in anthropogenic and share with its habitat and graze food and fodders with domestic herbivore mammals like goat, buffalos’ and cow in the periphery of the village’s areas. The domestication of Nilgai corresponds to a pivotal change in history not only of humanity but also of the biosphere.

Evaluation of Various Nitrogen Indices in N-Fertilizers with Inhibitors in Field Crops: A Review

Nitrogen (N) management remains a global challenge for the sustainability of diversified farming systems. Field crops are often over-supplied with nitrogen by farmers aiming to high productivity. Although the increase of nitrogen rates leads in many instances to high yields, degree of effectiveness for nitrogen use remains low. Urease and nitrification inhibitors are technologies which have been present in the fertilizers market at least 50 years. Inhibitors exploitation ensures long-term nitrogen release and improved N-uptake by plants and N-storage in seeds and silage. Avail of inhibitors, such as the decline of nitrogen leaching in form of NO3−, reduction of emissions in NH3 form, and rise of yield, are some of the desirable attributes that are derived from their integration in fertilization schedules. This review reports the evaluation of applied nitrogen, with inhibitors, and field crops based on nitrogen indices. The examined N-indicators include Nitrogen use efficiency (NUE), Nitrogen Utilization Efficiency (NUtE,) Nitrogen Agronomic Efficiency (NAE), Nitrogen Harvest Index (NHI), and N uptake. This review gathered all, to the best of our knowledge, available data regarding the utilization of nitrification and urease inhibitors under an exclusively agronomic perspective. Either dual or single use of nitrification and urease inhibitors has been reported to significantly increase yield components and promote nitrogen uptake. To conclude, the assessment of N-related indices is vital to promoting sustainability in diversified farming systems, while the integration of inhibitors in national N fertilizations schemes may contribute to system profitability through enhancement of N-supply to crops.

Micro and Macro-level Analysis of Crop Diversification: Evidence from an Agrarian State West Bengal

The farming system in West Bengal is being shifted by integration between the set of cash crops and the main food harvest process. This change in diversified farming systems, where smallholders have a production base in rice can complement production; affect technical efficiency and farm performance. The goal of this study was to investigate the status of crop diversification on smallholders in West Bengal. First, crop diversification regions were developed in West Bengal based on the Herfindahl index, which were categorized into three regions. Three sample districts were studied separately at the block level, and 915 small farmers from 41 sample villages of 9 sample blocks were interviewed through a good structure questionnaire for field studies from the sample districts. West Bengal was gradually moving towards multiple crop production. Furthermore, increasing rice production reduced the marginal use of inputs for the production of other crops. Farming and other vital factors such as HYVs area to GCA, average holding size and per capita income in some districts of West Bengal can be identified as determinants of crop diversification.

Sustainable Agricultural Systems: A Bibliometrics Analysis of Ecological Modernization Approach

Agricultural systems need to be more sustainable. Nowadays, the global food production has a remarkable impact in terms of greenhouse gases production, terrestrial acidification, eutrophication and land consumption. Moreover, one of the effects of unsustainable agriculture is depletion of ecosystem services (ES) on which agricultural systems themselves are dependent. Alternative agricultural systems are possible: the aim of this review was to analyze one of these alternative systems, i.e., strong ecological modernization, to understand relevant topics and current state of the art connected with it. As a result that strong ecological modernization can be considered an ecosystem services-based farming system, we focused on the development of topics related to ecosystem services but also to diversification. The review has been conducted applying a bibliometrics approach to recognize the main papers, authors, organization and countries, as well as trend topics and main themes investigated. The results showed that basic research content involves agrobiodiversity, agroecology and diversified farming systems. At the same time, the review revealed a lack about the social and economic dimensions of sustainability that need to be addressed for promoting a true transition to a strong ecological modernization.

Beyond Sustainability in Food Systems: Perspectives from Agroecology and Social Innovation

Food security faces many multifaceted challenges, with effects ranging far beyond the sectors of agriculture and food science and involving all the multiscale components of sustainability. This paper puts forward our point of view about more sustainable and responsible approaches to food production research underlying the importance of knowledge and social innovation in agroecological practices. Increased demand for food worldwide and the diversification of food choices would suggest the adoption of highly productive, but low-resilient and unsustainable food production models. However, new perspectives are possible. These include the revitalization and valorization of family-based traditional agriculture and the promotion of diversified farming systems as a social and economic basis to foster social-ecological conversion. Additionally, they encompass the forecasting of the Participatory Guarantee Systems (PGS) and the drafting of a new agenda for food sovereignty. Thanks to a desk analysis, the study describes and discusses these perspectives, their trajectories and action research implications. The results suggest the need to adopt a more inclusive and systemic approach to the described problems, as the solutions require the promotion of responsibility within decision makers, professionals and consumers. This appears essential for reading, analyzing and understanding the complex ecological-functional, social and economic relations that characterize farming systems, as well as mobilizing local communities.
