RESUMEN

Soil moisture plays an important role in ecology, hydrology, agriculture and climate change. This study proposes a soil moisture prediction model, based on the depth and water balance equation, which integrates the water balance equation with the seasonal ARIMA model, and introduces the depth parameter to consider the soil moisture at different depths. The experimental results showed that the model proposed in this study was able to provide a higher prediction accuracy for the soil moisture at 40 cm, 100 cm and 200 cm depths, compared to the seasonal ARIMA model. Different models were used for different depths. In this study, the seasonal ARIMA model was used at 10 cm, and the proposed model was used at 40 cm, 100 cm and 200 cm, from which more accurate prediction values could be obtained. The fluctuation of the predicted data has a certain seasonal trend, but the regularity decreases with the increasing depth until the soil moisture is almost independent of the external influence at a 200 cm depth. The accurate prediction of the soil moisture can contribute to the scientific management of the grasslands, thus promoting ecological stability and the sustainable development of the grasslands while rationalizing land use.

RESUMEN

Sustainable development of agriculture is the basis for achieving social sustainable development. As the basic industry of national economy, green development of agriculture has become an important support for building an environment-friendly society. Agricultural fiscal expenditure is a direct channel for the government to support agriculture and promote agricultural transformation. It is important to analyze the impact of agricultural fiscal expenditure (AFE) on agricultural green total factor productivity (AGTFP) for sustainable agricultural development. Therefore, this paper employs the random effect model and spatial Durbin model to empirically analyze the direct effect and spatial spillover effect of AFE on AGTFP by using the agricultural panel data of 30 provinces in China from 2008 to 2020. Then, by taking the policy proposal as the time node, this paper also conducts a time heterogeneity analysis to measure the impact of policy enactment on AFE and AGTFP. The main conclusions are as follows: (1) AGTFP exists significant positive spatial spillover effect. The "radiation effect" of agricultural green development is significant. (2) AFE can significantly reduce the AGTFP in the local area, that is, 1% increase of AFE in the local area will reduce AGTFP by 0.037%. At present, agriculture is still yield-oriented. The improvement of AFE in the local area will lead to the expansion of local agricultural production and increase pollution emission. (3) AFE has a significant negative spatial spillover effect on AGTFP, that is, for every 1% increase in AFE, the AGTFP will decrease 0.123% in geographically similar areas, while the AGTFP will decrease by 0.116% in economically and geographically similar areas. It is obvious that AFE will promote the optimization of agricultural production conditions in the province, with the "demonstration effect" on the surrounding areas, the enthusiasm of production in the surrounding areas will increase, thus expanding the pollution emission. (4) According to the analysis of different periods, AFE has a negative impact on AGTFP mainly before the reform innovation is proposed in 2015. It indicates that reform policies have a significant impact on agricultural sustainability.

RESUMEN

Transformation pathways for the land sector in line with the Paris Agreement depend on the assumption of globally implemented greenhouse gas (GHG) emission pricing, and in some cases also on inclusive socio-economic development and sustainable land-use practices. In such pathways, the majority of GHG emission reductions in the land system is expected to come from low- and middle-income countries, which currently account for a large share of emissions from agriculture, forestry and other land use (AFOLU). However, in low- and middle-income countries the economic, financial and institutional barriers for such transformative changes are high. Here, we show that if sustainable development in the land sector remained highly unequal and limited to high-income countries only, global AFOLU emissions would remain substantial throughout the 21st century. Our model-based projections highlight that overcoming global inequality is critical for land-based mitigation in line with the Paris Agreement. While also a scenario purely based on either global GHG emission pricing or on inclusive socio-economic development would achieve the stringent emissions reductions required, only the latter ensures major co-benefits for other Sustainable Development Goals, especially in low- and middle-income regions.

RESUMEN

In recent years, the rapid increase in the global population, the challenges associated with climate change, and the emergence of new pandemics have all become major threats to food security worldwide. Consequently, innovative solutions are urgently needed to address the current challenges and enhance food sustainability. Green technologies have gained significant attention for many food applications, while the technologies of the fourth industrial revolution (Industry 4.0) are reshaping different production and consumption sectors, such as food and agriculture. In this review, a general overview of green and Industry 4.0 technologies from a food perspective will be provided. Connections between green food technologies (e.g., green preservation, processing, extraction, and analysis) and Industry 4.0 enablers (e.g., artificial intelligence, big data, smart sensors, robotics, blockchain, and the Internet of Things) and the Sustainable Development Goals (SDGs) will be identified and explained. Green and Industry 4.0 technologies are both rapidly becoming a valuable part of meeting the SDGs. These technologies demonstrate high potential to foster ecological and digital transitions of food systems, delivering societal, economic, and environmental outcomes. A range of green technologies has already provided innovative solutions for major food system transformations, while the application of digital technologies and other Industry 4.0 technological innovations is still limited in the food sector. It is therefore expected that more green and digital solutions will be adopted in the coming years, harnessing their full potential to achieve a healthier, smarter, more sustainable and more resilient food future.

RESUMEN

Ecological agricultural technology is the key method for making the transition from traditional agriculture to ecological agriculture, and is also the basic measure for promoting the transformation and upgrading of the tea industry and sustainable development. This study explores the influencing factors and mechanisms of tea farmers' adoption of ecological agricultural technology by using the extended model of the unified theory of technology adoption and use (UTAUT) based on perceived value. The analysis results, using the partial least squares structural equation model (PLS-SEM), show that: the positive impact of perceived value on willingness to use not only makes the explanatory power of the extended model greater than that of the original model but also expands the UTAUT model into a full mediating model, in which performance expectation has the greatest impact on behavioral intention through the implemented value. Effect expectation, social influence and factoring factors following, then the four intermediary paths have significant positive effects on behavioral intention. This study improves on the limitations of the UTAUT theoretical model through the theory of perceived value, and provides a reference for research on the same topic. At the same time, the government should provide tea farmers with enhanced subsidies, skills training and communication platforms.

RESUMEN

Agriculture is particularly essential in the equilibrium between man and nature because of its intimate contact with nature. So the cornerstone for the sustainable development of the human economy and society is the sustainable development of agriculture. When it comes to global trade, agricultural trade has always been in a very special position. The basic situation of agriculture involves food safety, environmental protection, Chinese politics, and many other issues. In order to overcome the problems of overlapping, repetitive, and too many indicators in the evaluation method of agricultural environmental sustainable development and unfavorable for practical operation, this paper proposes an ecological footprint model based on emergy. The model can effectively evaluate the ability of sustainable development of agricultural environment and solve the problem that traditional evaluation methods cannot comprehensively evaluate. This makes agricultural development sustainable and is conducive to the liberalization of international agricultural trade. The experimental results of this paper show that from 2014 to 2018, the degree of damage to the agricultural environment has increased from 21% to 45%, which has led to a decline in the quality of agricultural products, and the output and sales are not as good as before. It can be seen that only by ensuring the sustainable development of the agricultural environment can we ensure the smooth progress of the international agricultural trade liberalization and make China's economy flourish.

RESUMEN

China's goal of becoming a strong agricultural country cannot be achieved without the modernization and digital transformation of the agricultural sector. Presently, China's agriculture has ushered in the era of digital economy transformation. The digital transformation of agriculture has played a huge role in improving agricultural productivity, promoting sustainable development of China's agricultural economy, and achieving sustainable development goals. The deep integration of digital economy and agricultural economy has become an important issue of The Times. This study uses a two-way fixed-effects model and an instrumental variable method to examine the impact of environmental regulation on agricultural total factor productivity. Using the method of mechanism analysis, the conduction path of improving agricultural productivity under the means of environmental regulation is discussed. Therefore, the visualization analysis results based on the panel data of Chinese agricultural enterprises from 2011 to 2019 show that the distribution of digital transformation and productivity level of enterprises is uneven and tends to be stable in space. The empirical analysis results show that there is a direct and significant positive relationship between voluntary environmental regulation and agricultural total factor productivity. The results of mechanism analysis show that, under the means of environmental regulation, digital transformation plays an indirect role in improving agricultural productivity. On the basis of enriching and deepening the theoretical extension of the "Porter Hypothesis", this study subtly incorporates environmental regulation, digital transformation, and agricultural productivity into a unified framework, expanding existing research.

RESUMEN

The green transformation of production modes plays an essential role in the sustainable development of China's agriculture and the modernization process, but there is often a deviation between farmers' behavior and their willingness regarding green production. This paper analyzed the factors influencing the deviation of farmers' green production behaviors from their willingness, along with their hierarchical logic structure, using the ordered logit model and ISM model with field survey data of 436 households in Hainan Province. The results show that: (1) there are deviations between farmers' green production behavior and willingness; (2) age, number of dependents, peer influence, and social networks aggravate farmers' green production behavior-willingness deviation, while ethnicity, education, land fragmentation, agricultural expenditure, land transfer, neighborhood learning, and green production cognition mitigate the deviation; (3) among the significant influencing factors, farmers' perceptions of green production, peer influence, land transfer, and agricultural expenditure are the direct surface factors, while neighborhood learning, land fragmentation, and number of dependents are the middle indirect factors, and farmers' education, social networks, age, and ethnicity are the deep-rooted factors. This study sheds more light and detail on the understanding of the factors influencing farmers' green production behavior-willingness deviation, and provides more practical and relevant guidance for the agricultural green development in tropical China.

RESUMEN

Small farmers produce most food in low- and middle-income countries and most small farmers rely on directly or indirectly working equids (WE). The lack of methods and metrics for assessing the role of WE hampers realisation of WE contributions. Based on literature review and a survey of WE welfare experts, we propose a framework for optimising WE potential based on two axes of sustainable development goals (SDGs) and value chains. WE contribute especially to earning and sparing income (largely in food production) (SDG 1), but also have roles in accessing health and hygiene services and products (SDG 3 and 5), providing edible products (SDG 2), and benefiting women (SDG 6), with lesser contributions to other SDGs, notably climate action (SDG 13). Experts identified barriers to appropriate appreciation of WE contributions, in order to target actions to overcome them. They found WE are neglected because they belong to farmers who are themselves neglected; because information on WE is inadequate; and, because the unique nature and roles of WE means systems, policies, investors, markets and service providers struggle to cater for them. Harnessing WE to optimally contribute to sustainable development will require generating better evidence on their contributions to SDGs, ensuring better integration into ongoing efforts to attain SDGs, and building the WE capacity among development actors.

RESUMEN

Cleaner household energy for agricultural green production can significantly alleviate energy poverty and food security, thus contributing to global sustainable development. Using survey micro-data collected from Sichuan Province, the ordered probit model, OLS model, and instrumental variables approach were applied for empirical analysis. The results show that: (1) cleaner household energy significantly enhances farmer's agricultural green production awareness and improves agricultural green production levels, which is still significant after treating endogenous issues with the conditional mixing process estimation method and 2SLS model; (2) health plays a partially mediating effect of cleaner household energy on agricultural green production awareness and agricultural green production levels; (3) environmental protection awareness and digital literacy have a moderating effect and reinforce the positive impact of cleaner household energy on agricultural green production awareness and agricultural green production levels. This research suggests that governments can enhance the impact of cleaner household energy on agricultural green production through price and subsidy mechanisms.

RESUMEN

Poverty, food insecurity and climate change are global issues facing humanity, threatening social, economic and environmental sustainability. Greenhouse cultivation provides a potential solution to these challenges. However, some greenhouses operate inefficiently and need to be optimized for more economical and cleaner crop production. In this paper, an economic model predictive control (EMPC) method for a greenhouse is proposed. The goal is to manage the energy-water­carbon-food nexus for cleaner production and sustainable development. First, an optimization model that minimizes the greenhouse's operating costs, including costs associated with greenhouse heating/cooling, ventilation, irrigation, carbon dioxide (CO2) supply and carbon emissions taking into account both the CO2 equivalent (CO2-eq) emissions caused by electrical energy consumption and the negative emissions caused by crop photosynthesis, is developed and solved. Then, a sensitivity analysis is carried out to study the impact of electricity price, supplied CO2 price and social cost of carbon (SCC) on the optimization results. Finally, a model predictive control (MPC) controller is designed to track the optimal temperature, relative humidity, CO2 concentration and incoming radiation power in presence of system disturbances. Simulation results show that the proposed approach increases the operating costs by R186 (R denotes the South African currency, Rand) but reduces the total cost by R827 and the carbon emissions by 1.16 tons when compared with a baseline method that minimizes operating costs only. The total cost is more sensitive to changes in SCC than that in electricity price and supplied CO2 price. The MPC controller has good tracking performance under different levels of system disturbances. Greenhouse environmental factors are kept within specified ranges suitable for crop growth, which increases crop yields. This study can provide effective guidance for growers' decision-making to achieve sustainable development goals.

RESUMEN

Based on China's provincial panel data from 2007 to 2019, this article discusses the impact of agricultural insurance on agricultural green development, and discusses the issue of regional heterogeneity. This article first studies the impact mechanism of agricultural insurance on agricultural green development, calculates the agricultural green development index, and empirically analyzes the impact of agricultural insurance on agricultural green development. The empirical results show that agricultural insurance has an inhibitory effect on agricultural green development, and that the impact of agricultural insurance on agricultural green development in the three functional areas is heterogeneous. Finally, it puts forward countermeasures and suggestions to build a low-carbon subsidy mechanism for agricultural insurance, enrich agricultural insurance products, improve the coverage of agricultural insurance, and build an agricultural production mode of internal planting and breeding combined with recycling through policy incentives.

RESUMEN

The majority of worldwide trading in live arthropods is done by specialised companies that produce and distribute beneficial insects, mites and nematodes for augmentative biological control of pests on crops. These beneficial arthropods, predators or parasitoids of crop pests and some nuisance species, which are harmless to humans, plants and other animals, are mass-reared, transported and released in the target environment as a viable alternative to chemical pesticides. As such, they play a major role in achieving a more sustainable and regenerative agriculture. Thousands of international air shipments are performed yearly by up to 30 major companies. Over the decades that this industry has been active, no significant transport problems have arisen. This is due to stringent standards that the industry has generated, including designated departments to deal with quality control and logistics, as well as guides for each species concerning packaging, storage and transport conditions. In addition, transporters always adhere to the regulatory standards of the importing and exporting countries, which is attested to by the documents included by the companies with each shipment. Two major issues arise when shipping live arthropods: first, the need to maintain stable environmental conditions within the shipping units (maintaining a cool chain) and, second, minimising transport time (preventing delays). This paper discusses the procedures implemented by the companies to assure quality, the documents required and provided currently, and the challenges to the safe transportation of beneficial organisms.


L'essentiel du commerce mondial d'arthropodes vivants est réalisé par des entreprises spécialisées qui produisent et distribuent des insectes, des acariens et des nématodes utiles à des fins de lutte biologique augmentative contre les ravageurs des cultures. Ces arthropodes utiles agissent en tant que prédateurs ou parasitoïdes des espèces de ravageurs ou de nuisibles s'attaquant aux cultures, tout en étant inoffensifs pour l'homme, les végétaux et les autres animaux ; ils font l'objet d'un élevage de masse et sont transportés et relâchés dans l'environnement cible où ils constituent une alternative viable aux pesticides chimiques. À ce titre, ils jouent un rôle majeur en appui d'une agriculture plus durable et régénératrice. Près de 30 grandes entreprises effectuent chaque année des milliers d'expéditions internationales par avion. Aucun incident significatif lié au transport n'a été constaté au cours des décennies d'existence de ce secteur d'activités. Cela est dü aux normes strictes mises en oeuvre par le secteur, en particulier la mise en place de services chargés du contrôle de la qualité et de la logistique ainsi que l'élaboration de guides décrivant, pour chaque espèce, les exigences en matière de conditionnement, de stockage et de transport. En outre, les transporteurs se conforment toujours aux normes réglementaires des pays importateurs et exportateurs, comme l'attestent les documents d'accompagnement fournis par les entreprises lors de chaque expédition. Le transport d'arthropodes vivants présente deux difficultés majeures : d'une part, la nécessité de garantir la stabilité des conditions environnementales au sein des unités d'expédition (respect de la chaîne du froid) et, d'autre part, l'impératif de minimiser le temps de transport (prévention des retards). Les auteurs examinent les procédures mises en oeuvre par les entreprises en termes d'assurance qualité, les documents actuellement requis et fournis ainsi que les défis posés à la sécurité des transports d'organismes utiles.


El grueso del comercio mundial de artrópodos vivos está a cargo de empresas especializadas que producen y distribuyen insectos, ácaros y nemátodos beneficiosos que se destinan al control biológico aumentativo de plagas de los cultivos. Estos artrópodos beneficiosos, predadores o parasitoides de las plagas de los cultivos y otras especies dañinas, son a la vez inocuos para humanos, plantas y otros animales. Tras ser criados a gran escala y transportados, son liberados en el medio destinatario como alternativa viable a los plaguicidas químicos. Cumplen, en este sentido, una función capital para posibilitar una agricultura más sostenible y regeneradora. Cada año, hasta 30 grandes empresas efectúan miles de envíos internacionales por vía aérea. En los varios decenios que este sector lleva activo, nunca ha surgido ningún problema importante de transporte, gracias a las rigurosas normas implantadas por el sector, que incluyen departamentos dedicados específicamente a las cuestiones de logística y control de calidad y guías sobre las condiciones de embalaje, almacenamiento y transporte de cada especie. Además, los transportistas siempre se atienen a la normativa de los países importadores y exportadores, como atestigua la documentación con que las empresas acompañan cada envío. Al transportar remesas de artrópodos vivos hay dos grandes imperativos que plantean sendas dificultades: en primer lugar, el de mantener estables las condiciones del medio en las unidades de transporte (mantenimiento de la cadena del frío); y en segundo lugar, el de reducir al mínimo el tiempo de transporte (evitar demoras). Los autores examinan los procedimientos de garantía de calidad implantados por las empresas, los documentos requeridos y presentados actualmente y las dificultades que plantea el transporte seguro de organismos beneficiosos.

RESUMEN

Honeybee pollination plays a significant role in sustaining the balance and biodiversity of sustainable rural development, agricultural production, and environments. However, little research has been carried out on the agricultural and economic benefits of pollination, especially for small farmers. This study investigated the adoption of honeybee pollination and its impact on farmers' economic value using primary data from 186 kiwifruit farmers in three major producing districts, such as Pujiang, Cangxi, and Dujiangyan, in the Sichuan province of China. This study was conducted in two different steps: first, we used a bivariate probit model to estimate factors influencing honeybee pollination and artificial pollination adoption; second, we further used the Dynamic Research Assessment Management (DREAM) approach to analyze the influence of the adopted honeybee pollination economic impact. The results showed that: (1) growers with higher social capital, proxied by political affiliation, are more aware of quality-oriented products, and older growers tend to choose less labor-intensive pollination technology; (2) with the increase in labor costs, more kiwifruit growers would choose honeybee pollination, and more educated growers, measured by the number of training certificates, are more likely to adopt honeybee pollination; (3) the lack of awareness and access to commercial pollinating swarms hinders the adoption of honeybee pollination; (4) in addition to the economic benefit to producers, honey pollination also brings an even larger consumer surplus. This study suggests some policy recommendations for promoting bee pollination in China: raising farmers' awareness and understanding of bee pollination through training, promoting supply and demand in the pollination market, and optimizing the external environment through product standardization and certification.

RESUMEN

As a complementary and symbiotic agro-ecological cycle system, a nature-based integrated rice-fish-duck farming ecosystem was developed in the Honghe Hani Rice Terraces. The main research objective was to evaluate the ecosystem services based on case studies of the Hani integrated rice-fish-duck terraced farming system and determine its potential and its importance as an ecological asset. We developed a valuation model to assess the value of the integrated farming system based on the three aspects of provisioning, regulation and maintenance, and cultural services; we selected eight groups and 10 indictors to evaluate the ecosystem services of the integrated ecosystem in Honghe Hani Rice Terraces was 3.316 billion CNY, of which the provisioning service value was 1.76 billion CNY, the regulation and maintenance service value was 1.32 billion CNY, and the cultural services value was 230.85 million CNY. The evaluation will be useful as a theoretical reference for poverty alleviation policy makers in similar poverty-stricken areas, enabling them to better protect and promote this mode of farming and further promote the protection of the natural environment and cultural heritage alongside the sustainable development of natural resources and human well-being.

RESUMEN

Farming' community actively participating as micro-actors in green finance schemes is critical for regional planning and development. On the basis of the extent to which financial progress and sustainable development are coordinated, in a difference-in-differences approach, this article employed 2350 small investigations to estimate the influence of green-finance strategies on peasants' agriculture investment and developed a mediation effect method. It investigates the role of peasant managerial variability in mediating the influence of financial constraints. The results indicate that the introduction of a financial restriction variable reduces the positive impacts of green-finance regulations on peasants' agricultural investment. Moreover, peasants who participate in non-agricultural management exercises are more inclined to take advantage of green financing regulations and are affected via financial restrictions in mediate means. The building of a green-finance sector in remote regions should accomplish unique positioning and rapid growth.

RESUMEN

Agricultural intensification and expanding protected areas are proposed sustainable development approaches. But, their consequences for mental health are poorly understood. This study aims to predict how forest conservation and contract farming may alter resource access and depression risk in rural Uganda. Residents (N = 695) in 11 communities in Masindi District were asked about their expectations under land management scenarios using scenario-based interviews, household characteristics and depression symptoms. Over 80% of respondents presented with a 'business-as-usual forest access' scenario expected reduced access to forest income and food over the next decade; this number climbed above 90% among 'restricted forest access' scenario respondents. Over 99% of those presented with two land access scenarios ('business-as-usual land access' and 'sugarcane expansion land access') expected wealthy households to gain land but poorer families to lose it, threatening to increase poverty and food insecurity among small-scale farmers. Bayesian structural equation modelling suggested that depression severity was positively associated with food insecurity (0.20, 95% CI = 0.12-0.28) and economic poverty (0.11, 95% CI 0.02-0.19). Decision-makers should evaluate the mental health impacts of conservation and agricultural approaches that restrict access to livelihood resources. Future research could explore opportunities to support mental health through sustainable use of nature.

RESUMEN

RESUMEN La complejidad e incertidumbre de transformar los sistemas de producción agrícola futuros en sistemas sostenibles requiere de evaluaciones holísticas y prospectivas, que involucren las interacciones dinámicas, entre agricultura, economía, sociedad y medio ambiente. En este sentido, se requieren modelos holísticos, que incluyan la prospectiva estratégica y el desarrollo territorial en la evaluación de la sostenibilidad de estos sistemas, a escala regional. Este documento, a través de análisis bibliográfico 1) identifica los avances en prospectiva estratégica, ordenación territorial y evaluaciones de impacto territorial en el contexto agrícola y los enfoques integrales de evaluación de la sostenibilidad agrícola a escala regional y 2) genera las bases para una nueva aproximación de la evaluación de la sostenibilidad del sistema agrícola a escala regional y del desarrollo territorial, con base en los avances identificados. Los resultados muestran que la prospectiva estratégica, la ordenación del territorio y las evaluaciones de impacto territorial han avanzado en un enfoque integral proporcionando, además, una visión y evaluación estratégica de los sistemas. Así, también, se mencionan como factores de éxito, el establecimiento de una buena gobernanza, la co-creación de los escenarios estratégicos, el uso de unidades homogéneas en la planificación, una amplia disponibilidad de datos ambientales y sociales con resolución espacial y temporal y la inclusión de nuevas herramientas analíticas y computacionales. La proyección del trabajo vincula los objetivos de la evaluación de los sistemas agrícolas para el desarrollo territorial sostenible, en un marco de acción integral.


ABSTRACT The complexity and uncertainty of transforming future agricultural production systems into sustainable systems require holistic and prospective evaluations that understand the dynamic interactions between agriculture, the economy, society, and the environment. In this sense, holistic models need that include strategic foresight and territorial development in evaluating the sustainability of these systems on a regional scale. This document, through bibliographic analysis: 1) identifies the advances in strategic foresight, land use planning, and land impact assessments in the agricultural context and comprehensive approaches to assessing agricultural sustainability at a regional scale; and, 2) it generates the bases for a new approach to the evaluation of the sustainability of the agricultural system on a regional scale and territorial development based on the advances identified. The results show that strategic foresight, spatial planning, and territorial impact evaluations have advanced in a comprehensive approach, providing a vision and strategic evaluation of the systems. The establishment of good governance, the co-creation of strategic scenarios, homogeneous units in planning, the wide availability of environmental and social data with a spatial and temporal resolution, and the inclusion of new ones are considered success factors-analytical and computational tools. The projection of the work links the objectives of the evaluation of agricultural systems for sustainable territorial development in a comprehensive action framework.
