An Overview of Selected Tools and Strategies for Agricultural Land Protection in Slovakia and the European Union
Agricultural land, as a component of the environment, is one of the irreplaceable natural resources and, at the same time, through its functions, is an integral part of the quality of human lives. Several international institutions or scientists point to problems with land loss or decline in quality and, ultimately, to the increased need for soil protection, based on which governments implement various tools. The aim of the paper is therefore to compile a general overview of existing tools for the protection of agricultural land in Slovakia and to analyse selected strategies for land protection in the EU. The main source of information was represented by literary sources of publications by scientific researchers, Slovak and European bodies or institutions, and, last but not least, legal acts. The paper points to a wide range of existing tools and innovative strategies for the protection of agricultural land in Slovakia and the EU.

Agricultural Land Suitability Analysis for Land Use Planning: The Case of the Madrid Region
Agricultural land is a key resource for territorial resilience. In the European context, fertile soils are under pressure not only from urbanisation processes, abandonment and the establishment of non-agricultural uses but also from agriculture that is not well adapted to territorial resources. In order to inform urban planning, a methodology is proposed and applied to the Madrid region to analyse the suitability of agricultural land uses with respect to agrological quality. The majority of agricultural uses in the region are well adapted to the agroecological quality of the land; larger areas of over-exploited land are located along some of the region’s rivers and in the Campiña, while under-utilised land is mainly found in the south-west and in the metropolitan comarcas. This methodology is based on official and open-access information, so it can be easily replicated and used to inform land planning. We propose three strategies depending on the suitability of land use: the introduction of crops in priority areas for horticulture or arable crops, agricultural protection areas and ecological regeneration areas.

Pesticides, a love story : America's enduring embrace of dangerous chemicals
\"A provocative cultural history of pesticides and their controversial use and depiction in the United States. Mart contends that--despite the sharp concerns raised by environmentalists and others since the appearance of Rachel Carson's Silent Spring--Americans have not only never resolved the inherent tension between costs and benefits presented by these chemicals, but have actually grown ever more attached to them with the passage of time\"-- Provided by publisher.

Distortion of agricultural incentives in East Africa: effects on agricultural value added
This study examines the effects of distortion of agricultural price incentives on agricultural value added in East Africa. The World Bank, IFPRI, FAO, and CSP are the sources of data. The dataset ranges from 1981 to 2018, and the error-corrected LSDV model is used to analyze the data. The results indicate that agricultural price incentives have positive and significant effects on agricultural value-added. Aggregate nominal assistance coefficient, exportable agricultural products nominal assistance coefficient, and nominal rate of protection have increased agricultural value-added significantly. Agricultural price incentives targeting different levels of value addition have larger effects than those targeting aggregate outputs. This implies that agricultural incentive policies and market conditions in support of local producers are vital to enhancing AVA in East Africa. Besides, larger areas of arable land, lower agricultural employment, a smaller population size, a larger GDP, less spending on education, and a better-performing polity contribute to a significant increase in the regional agricultural value added. The results generally imply that agricultural price incentives are vital to accelerating agricultural value addition in East Africa. Governments in this region should thus consider revising agricultural policies in a pro-agricultural way to further accelerate regional growth in agricultural value-added. Enhancing agricultural price support needs to be a crucial element of policy revisions in the region. In East Africa, agriculture is the main source of employment for a large section of the population. However, agricultural incentives have been reportedly distorted against agriculture, and sectoral income has been low. Consequently, farmers' income from agricultural value addition has been low. This study reports the effects of the distortion of agricultural incentives on agricultural value added in East Africa. The study shows that favorable agricultural incentives enhance agricultural value-added. The findings have strong implications for the region's smallholders, who are the subject of heavy taxation, either directly or indirectly. It will have far-reaching consequences for the poor, who rely on agriculture for a living. In particular, the findings influence regional anti-agricultural policy design, which is vital for the regional goal of achieving inclusive growth and structural transformation.

YOLOv7-Based Intelligent Weed Detection and Laser Weeding System Research: Targeting Veronica didyma in Winter Rapeseed Fields
In recent years, rapeseed oil has received considerable attention in the agricultural sector, experiencing appreciable growth. However, weed-related challenges are hindering the expansion of rapeseed production. This paper outlines the development of an intelligent weed detection and laser weeding system—a non-chemical and precision agricultural protection method of weeding Veronica didyma in winter rapeseed fields in the Yangtze River Basin. A total of 234 Veronica didyma images were obtained to compile a database for a deep-learning model, and YOLOv7 was used as the detection model for training. The effectiveness of the model was demonstrated, with a final accuracy of 94.94%, a recall of 95.65%, and a mAP@0.5 of 0.972 obtained. Subsequently, parallel-axis binocular cameras were selected as the image acquisition platform, with binocular calibration and semi-global block matching used to locate Veronica didyma within a cultivation box, yielding a minimum confidence and camera height values of 70% and 30 cm, respectively. The intelligent weed detection and laser weeding system was then built, and the experimental results indicated that laser weeding was practicable with a 100 W power and an 80 mm/s scanning speed, resulting in visibly lost activity in Veronica didyma and no resprouting within 15 days of weeding. The successful execution of Veronica didyma detection and laser weeding provides a new reference for the precision agricultural protection of rapeseed in winter and holds promise for its practical application in agricultural settings.

Comparative Study of Bacillus-Based Plant Biofertilizers: A Proposed Index
The market for bacteria as agricultural biofertilizers is growing rapidly, offering plant-growth stimulants; biofungicides; and, more recently, protectors against extreme environmental factors, such as drought. This abundance makes it challenging for the end user to decide on the product to use. In this work, we describe the isolation of a strain of Bacillus velezensis (belonging to the operational group Bacillus amyloliquefaciens) for use as a plant-growth-promoting rhizobacterium, a biofungicide, and a protector against drought. To compare its effectiveness with other commercial strains of the same operational group, Bacillus amyloliquefaciens, we analyzed its ability to promote the growth of pepper plants and protect them against drought, as well as its fungicidal activity through antibiosis and antagonism tests, its ability to solubilize potassium and phosphates, and its ability to produce siderophores. Finally, we used a probit function, a type of regression analysis used to model the outcomes of analyses, to quantify the biostimulatory effectiveness of the different plant-growth-promoting rhizobacteria, developing what we have called the Agricultural Protection Against Stress Index, which allowed us to numerically compare the four commercial strains of the operational group Bacillus amyloliquefaciens, based on a Delphi method—a type of regression analysis that can be used to model a cumulative normal distribution—and integrate the results from our panel of tests into a single value.

Political Reforms and Public Policy: Evidence from Agricultural and Food Policies
This paper studies the effect of political regime transitions on public policy using a new data set on global agricultural and food policies over a 50-year period (including data from 74 developing and developed countries over the 1955-2005 period). We find evidence that democratization leads to a reduction of agricultural taxation, an increase in agricultural subsidization, or both. The empirical findings are consistent with the predictions of the median voter model because political transitions occurred primarily in countries with a majority of farmers. The results are robust to different specifications, estimation approaches, and variable definitions.

AGRICULTURAL SYSTEMS – ROLE AND IMPORTANCE IN THE ENVIRONMENT PROTECTION AND SUSTAINABLE RURAL DEVELOPMENT IN BANAT, ROMANIA
Researches were conducted in the Western area of the country, in the Banat Plain and concerned the sustainability of agricultural systems as production systems and means of sustainable rural development. Categories of use of the agricultural land in the county of Timis have suffered changes in the studied period with different amplitude from one category of use to another, also finding uncultivated and temporarily abandoned land. There were recorded changes in the structure of crop plants with implications on crop rotation and agricultural environment. In the studied viticulture systems we observed a high diversity of biological material but technologies show some malfunctions. During this period, the technical park has undergone an improvement both in number and quality even if an optimal level of endowment hasnt been reached yet. Through some indicators the increasing of performance and productivity of the agricultural systems are observed, but much too slow to ensure prosperity to farmers.
