In the EU, for example, the Nitrate Directive aims to control the nutrient levels in the water and agri-environmental schemes aim to protect habitats and increase biodiversity. The trade-offs between such environmental policies are not clear. Therefore, this paper studies the interaction between manure policy, especially derogation policy, and meadow bird schemes for the Netherlands. We develop a mathematical programming farm model with nine representative dairy farm types, based on location and economic size, that gain utility from both profit and agri-environmental services production. We show that the abolishment of derogation and the introduction of a low-protein feeding measure – both aimed at reducing nitrogen emissions – reduce total land contracted for meadow birds. This is because (1) without derogation makes farms switch to more maize production, hence reducing grassland, and (2) the protein measure requires extra feed production on-farm which most farms cannot accomplish and which makes contracting for the meadow bird scheme less attractive. Especially farms on peat and more intensive farms, who are more dependent on buying feed, reduce the amount of land contracted. We advocate that policy makers should become aware of how policies interact and that researchers do not study them in isolation.","PeriodicalId":211218,"journal":{"name":"NJAS: Impact in Agricultural and Life Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126893150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We conducted a stakeholder analysis using the Net-Map tool in Laikipia, Nakuru and Nyandarua counties in Kenya. VisuaLyzer software was used to analyse the social networks. Thematic content analysis of the discussions, recorded during the mapping exercise, was undertaken using ATLAS.ti. Formal DVC had more actors and dense social networks characterised by vertical and horizontal integration, high levels of power asymmetries between actors, limited trust and short-term contractual arrangements. Informal DVC was characterised by fewer actors and less dense social networks, low levels of power asymmetries between actors and a high level of trust due to the existence of reciprocal personal relationships. Milk was perceived to be of higher quality in the formal value chain reflecting top-down enforcement of milk standards, bottom-up collective action, power asymmetries and contractual relationships. Poor milk quality management in the informal DVC underscores the need for powerful actors, e.g. regulatory agencies, and buyers such as processors, to influence other DVC actors’ behavioural change. Understanding and leveraging DVC social networks and actors’ power and addressing power asymmetries and enhancing trust between actors will increase compliance with milk quality standards. There is an urgent imperative to design policies and interventions which empower DVC actors, by providing economic incentives, enhancing their skills and knowledge and their access to infrastructure which facilitates milk quality improvement.","PeriodicalId":211218,"journal":{"name":"NJAS: Impact in Agricultural and Life Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129079096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Climate variability and change impact crop production in numerous ways, including by changing occurrences of different rice diseases. Weather and climate information services (WCIS) can assist farmers in improving agricultural decision-making, in relation to rice disease management. Currently, however, farmers in coastal Bangladesh have limited access to accurate, timely, and location-specific information on weather and climate. To design actionable information services, it is important to know the types of information that farmers need. With this in mind, the current research addressed three questions: (i) What types of weather information do coastal farmers need to forecast rice diseases? (ii) What types of weather information are currently available to coastal farmers? (iii) How does weather information play a role in rice disease management-related decision-making? Results indicate that coastal rice farmers have access to weather and climate information services mainly through personal experiences, neighbouring farmers, agricultural extension agents, local knowledge and input dealers. During interviews, farmers indicated that they mainly needed information on temperatures, rainfall, relative humidity, cloud cover, fog and wind information to predict rice disease outbreaks sufficiently in advance. Raising awareness about application of climate information services in rice disease management and building the capacity of farmers through training and education is vital to address major challenges faced by the coastal farmers in accessing weather information. We conclude that the farmers need more accurate, timely, location-specific, trustworthy and actionable weather information services to forecast and manage rice diseases.","PeriodicalId":211218,"journal":{"name":"NJAS: Impact in Agricultural and Life Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115904272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, treating insects as mini-livestock is accompanied by various questions on the suitable rearing conditions needed to achieve high-quality products, while considering insect welfare. Although there are concepts which have long served as a compass for animal welfare regulations, these have been under increasing criticism. Also, they have been drawn up for vertebrate animals and are, therefore, not entirely applicable to insects. We hold that the development of commonly accepted methods for keeping insects as mini-livestock demands deep knowledge on insect biology and a dynamic discussion on insect welfare. We plead for an evaluation of the relevant ethical and empirical aspects of insect rearing conditions and for establishing welfare criteria based on these evaluations. By addressing several questions and uncertainties from an interdisciplinary perspective of entomology, animal ethics and philosophy of mind, we argue that taking into account current knowledge on insect biology could aid in the emergence of a novel, well-informed and integrated perspective on insect welfare. Ultimately, our goal is to trace the necessary biological factors for designing implementable and appropriate insect rearing conditions, in order to avoid ethical mistakes that have historically been made in animal production systems.","PeriodicalId":211218,"journal":{"name":"NJAS: Impact in Agricultural and Life Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115178297","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The case under analysis is a watershed management project that uses an integrated farm planning (PIP) approach to strengthen farmers’ stewardship capacities within the Manafwa watershed through interactive and dialogic ways of engaging and teaching farmers. Utilizing a transformative learning ecology (TLE) perspective, this study investigated features of the PIP approach that support transformative learning for socio-ecological stewardship in a rural context. Data was collected by interviewing eighteen farmers from different villages and PIP generations and all three PIP trainers of the project, and by observing training sessions as well as sensitisation workshops. As a main result, the study yielded new insights that can help enhance PIP-like learning configurations consisting of interconnected learning tenets, dimensions and processes. This enhanced learning configurating comprises an organic learning system that facilitates farmers to change their mindsets and redefine their values, perspectives, routines, and practices towards those that encourage socio-ecological stewardship. The TLE fostered by the PIP approach represents a useful heuristic that can guide and inspire both scholars and educators engaged in processes of cultivating socio-ecological stewardship in similar contexts.","PeriodicalId":211218,"journal":{"name":"NJAS: Impact in Agricultural and Life Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133471066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this model, some important criteria such as climatic variables, topographic factors, soil characteristics, ecological variables, environmental variables and developmental variables were evaluated and considered as spatial indicators. The thematic layers were classified based on agronomical requirements tables of organic farming and were overlaid based on Weighted Overlay Analysis (WOA) in ArcMap software. Final maps were separately generated and classified to five classes of suitability degree for spring and winter crops. According to the results of model, development of organic farming is possible for up to 14.72 and 17.76 percent of the current lands of Golestan Province in Iran for organic spring and winter cropping, respectively. In this research, we developed a land suitability model for organic farming based on the evaluation of spatial variables in Geographic Information System (GIS) and MCDA.

Agriculture is increasingly expected to ensure food security and food safety while at the same time considering the environmental aspects. AI in the agricultural sector offers the potential to feed a continuously growing global population and still contribute to achieving the UN’s Sustainable Development Goals (SDGs). Despite its promises, the use of AI in agriculture is still limited. We argue that the slow uptake is due to the diverse ways in which AI impacts the agri-food industry, due to the diversity of foods, supply chains, climates, and land in the agricultural sector. We propose that this is also exacerbated by ethical concerns arising from AI use, the varying degrees of technological development and skills, and the economic impacts of agricultural AI. A literature review of multiple disciplines in agricultural AI (economic, environmental, social, ethical, and technological) and a focus group of experts. AI-powered systems in agriculture raise various sets of concerns in multiple disciplines that need to be aligned to provide sustainable AI solutions for the agriculture domain. Our research proposes that it is important to adopt an interdisciplinary approach when developing AI in agriculture. AI in agriculture should be developed by interdisciplinary collaboration because it has a greater chance to be robust, economically-valuable and socially desirable, which may lead to greater acceptance and trust among farmers when using it.","PeriodicalId":211218,"journal":{"name":"NJAS: Impact in Agricultural and Life Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121453318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research extends earlier more conceptual research on digital twins in this domain. We find benefits in increased accuracy and impact because of the real-time data connection of digital twins to their real-life counterparts. Specification, availability and accuracy of relevant data sources are still major challenges. Specifically, when using digital twins for personalized advice, further research is needed on nontechnical aspects so that users will comply with the advice from the digital twins.

For this purpose, the authors examined the rationale of the public policies’ involvement from three perspectives: the justifications for policy interventions, what should be accomplished with the policies and how the policy interventions should be conducted. A systematic review of the literature enabled the identification of the two main interrelated roles of public policies. First, public policies have an important role in ensuring equitable digitalisation of the agri-food sector. In this role, they are expected to protect the public interests, the interests of farmers and other supply chain actors that have weak bargaining power or are less organised. The other main role of public policies is to be receptive to the opportunities presented by the development and implementation of digitalisation and to enable necessary innovation. The interrelation of the two roles underlines the importance of encouraging innovation to help the agri-food sector in meeting major challenges while avoiding the unintended consequences of the technological development for weaker parties. The findings of this paper serve as a basis for further research on the specific characteristics that governments and policymakers should possess to operationalise the expected policy roles.","PeriodicalId":211218,"journal":{"name":"NJAS: Impact in Agricultural and Life Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129555277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Farmers therefore aim to find cost-efficient fertilization plans, which is a complex and recurring optimization problem. This study analyses whole-farm fertilization plans to generate a deeper economic understanding of cost-efficient fertilization plans on farm level. Various fertilizer plans, obtained by a choice experiment, were grouped into “cost-efficient”, “average” and “cost-inefficient” solutions, using cluster analysis. Group differences were analysed by t-test to reveal the characteristics of cost-efficient solutions. In addition, the fertilizer optimization system IoFarm was used to simulate the effects of extreme changes in farm constellations on the fertilizer plan. Our results show that certain fertilizers are significantly more common in cost-efficient fertilizer plans: diammonium phosphate covers 81.8% of the phosphorus and 21.7% of the nitrogen supply; granular potash covers 100% of the potash supply. Compared to cost-efficient fertilizer plans, inefficient ones have higher annual surpluses of sulphur (+45.4 kg ha−1) and potash (+9.8 kg ha−1), incurring costs and impacting sustainability. Application costs represent a proportion of 5.2% of total costs, but play a minor role compared to other factors. Fertilizer prices were identified as the largest factor influencing the fertilizer plan. The results show that cost-efficient fertilizer plans are at the same time more sustainable, which also demonstrates the societal benefit of this study. The study provides a new and important contribution to the understanding of cost-efficient fertilizer plans at the farm level. Farmers benefit significantly from this contribution, as it shows opportunities to increase cost-efficiency.","PeriodicalId":211218,"journal":{"name":"NJAS: Impact in Agricultural and Life Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130122900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
