Antarctica is a region of the world where climate change visible in rapid melting glaciers. This particularly evident marginal zones, pace glacial retreat has systematically accelerated. The effective mapping these changes possible with use remote sensing methods. study assesses glacier margin positions between 1979 and 2018 Antarctic Specially Protected Area 128 (ASPA-128) on King George Island, South Shetland Islands, Antarctica. In 1979, 19.8 km2 area was glaciated. Over following 39...

Bioenergy production from animal waste can be a key driver to achieving bio-economy goals. Developing sector could help create opportunities for circular system where not only people and the planet will benefited, but it also provide economic profitability farmers, especially in post-Covid period. To this end, manure production, its nutrient content, bioenergy potential were estimated, along with their spatial distribution Lubelskie province, Poland. Farm-level data processed aggregated at...

The properties of soil constitute one the most important features environment that determine potential for food production in a given region. Knowledge texture and agroclimate allows proper selection species agrotechnics plant production. However, contrast to agroclimate, may show large spatial variation physical chemical characteristics within plot. In regions where diversity is so high available maps are not sufficient, only method precise mapping mosaic remote sensing. This paper presents...

Until the marketization of economy in 1990, practically there was no unutilised agricultural land Poland. After political transformation, use marginal and part small parcels located areas better soil suitability became unprofitable for economic reasons. Despite reform Polish agriculture, problem not using a large is constantly present. There are currently detailed data available on actual scale regionalisation structure landuse abandonment Due to above, objective this study fill knowledge...

Biogas development is expected to contribute the National Recovery and Resilience plan overcome COVID-19 shock. Estimation of agricultural biogas potential in economic terms can refining policies inciting effective sector development. In this paper, we attempt do so by modeling a chain from dedicated crops livestock waste. This was achieved coupling farming models industry partial equilibrium framework. allows for comprehensive investigation alternative measures technology, size, spatial...

Synergies between the Common Agricultural Policy (CAP) and deployment of bioeconomy that induces resource-efficient sustainable biomass production patterns are in core discussion for new CAP Poland. Proactive greening mechanisms likely to enable a large-scale diffusion willow plantation investigated this respect, including diversification schemes combined with incentives making more attractive farmers. A comprehensive approach modelling farm options is therefore provided by means an...

The aim of this study is to compare the farmers’ viewpoint on agricultural drought with results generated by national Agricultural Drought Monitoring System (ADMS) in 2021. authors attempted also indicate effective methods validating these results, which could serve as an objective tool appeal made available farmers a part administrative procedure or directly included monitoring system, which, apart from soil and meteorological conditions, would take into account actual condition crops...

Summary The current study presents status and the need for improvement of land distribution family agricultural holdings in Poland. assessment farm lands area between 1 300 ha has been made according to 2013 data provided by Polish Agency Restructuring Modernisation Agriculture (ARMA). Our analysis included totally app. 750,000 holdings. evaluation consolidation was based on two regional criteria proposed Regional Offices Geodesy Agri cultural Areas, i.e. plot size number plots within...

Abstract In this study, we aim to support the evidence-based policy in agricultural biogas production at regional level Poland. To do so, set up a decentralized decision framework, simultaneously taking into account sector heterogeneity, technology state-of-the-art and Polish institutional setting related renewable energy production. A partial equilibrium model simulates interactions, estimating market clearing prices quantities intersection of supply demand. The optimal number, size...

Fertilization of crops with nitrogen (N) contained in natural and/or mineral fertilizers is a common practice that has long been used agriculture.It due to the fact application this element dose adapted plant's nutritional needs strong yielding effect.However, plants usually take up and process into yield production only part applied.The level N uptake plant speciesspecific depends on numerous factors, especially input, soil characteristics weather conditions [1].Recently, efficiency...

This paper presents analyses of the potential use Sentinel-1 (S-1) and Sentinel-2 (S-2) imagery to generate models winter wheat growth under agricultural drought vs. normal conditions identified based on yield losses calculated in Agricultural Drought Monitoring System (ADMS). The carried out showed sensitivity satellite images determined ADMS. study was conducted a large region, West Pomeranian Voivodeship (NUTS PL42), analysis covered about 22,935 polygons with production that constituted...

Based on FAO data, the paper presents trends in nitrogen (N) input and output Poland. As N ( inp), from mineral fertilisers, manure application, biological fixation, deposition was included. The outputs out) include contained crop harvest (main products by-products). trend analyses were carried out for period before (1961–1989) after (1990–2018) changes political economic systems. Additionally, use efficiency NUE) surpluses S) are presented these periods. In both compared periods, mean...

The purpose of this paper was to estimate biomass and by-products from plant production (straw, hay, natural fertilizer) in Lubelskie province, as well demonstrate energy potential possible obtain maize a co-substrate for biogas production. estimates related assumptions show that region has high amounting 26 966.6 TJ/year, which can be gain area also possesses significant sources agricultural provide 195 350.8 dam3/year biogas, may converted into thermal – 5586.4 TJ/year or electricity 1241 GWh/year.

The main purpose of this paper was to present ammonia (NH3) emissions from agriculture, on a regional scale, in 2017, and identify recommendable agricultural practices limiting emissions. methodology used estimate based the approach National Centre for Emissions Management (KOBiZE). Analyses were statistical data Statistics Poland (GUS), 2017. results conducted study showed significant spatial differentiation agriculture. region Wielkopolska had highest NH3 at level 34.5 kg per ha UAA. Lower...

The purpose of this paper was the analysis available raw material resources for agricultural biogas production on a regional basis. substrates used in are, among others, animal waste (slurry) and maize silage. most suitable voivodships building micro plant 50-100 kWe using silage as only substrate are: dolnośląskie, lubuskie, pomorskie, warminsko-mazurskie, wielkopolskie zachodniopomorskie. In local districts located aforementioned there is also possibility plants producing from such as:...

The purpose of this paper was to show the changes in greenhouse gases emissions years 1990- 2016 from agriculture Poland context and legislation European Union. Fluctuations values methane nitrous oxide reporting period were also presented. conducted analysis shows that total GHG reduced by 36.2%, 41.8% 26.9% comparison 1990. main factors causing level specific differences number livestock usage mineral fertilizers. null

The study presents assessment of economic benefits possible to be obtained thanks restoring agricultural production on fallowed/abandoned land located arable parcels medium-good and medium quality classes in Poland. Unused areas appeared the 90s XX century, after political transformation. Currently, 1.3 million ha land, 281 thousand pastures 39 orchards still remain uncultivated, which is 14.6% total area. Modelling potential was conducted by using spatial analysis scale parcels. main...

The purpose of this study was to estimate nitrogen oxide emissions from soils used for agricultural purposes by voivodships. Compared N2O were estimated according the recommended IPCC (tier 1) method with simulated using DNDC 3) model. Analyses done crop rotation (winter rape, winter wheat, triticale) in four cropping systems. Moreover, rape and triticale cultivation showed lower constituted 1475% 13-76% emissions, respectively. use model also enabled determination factors, which have an...
