Określenie długoterminowych tendencji jest ważne dla praktyki gospodarczej. Badania obejmowały lata 2001-2019. Do pomiaru tendencji wykorzystano najlepiej dopasowaną do danych empirycznych funkcję trendu. Wykorzystano także indeksy, statystyczne oraz średnie tempo zmian, wskaźniki struktury. Produkcja mięsa drobiowego ogółem rosła przeciętnie w roku w tempie 3,4%. Udział największych producentów, w wytwarzaniu produkcji zmniejszył się z 62,7% w 2001 r. do 53, 9% w 2019 r., a zwiększył średnich i pozostałych. U największych i średnich producentów mięsa drobiowego, za wyjątkiem Meksyku i Japonii wzrost produkcji był większy niż konsumpcji, co spowodowało zwiększenie możliwości eksportowych lub ograniczenie importu. Tempo wzrostu eksportu było szybsze niż produkcji, co powodowało zwiększenie udziału eksportu w zagospodarowaniu produkcji. Import mięsa drobiowego jest bardziej rozproszony niż jego eksport. Udział 3-ch największych eksporterów w handlu światowym w 2001 r. wynosił 58,7%, a w 2019 r. 51,9%, a wskaźniki te dla 3-ch największych importerów wynosiły odpowiednio: 33,8% i 23,6%. W Polsce szybko rosła produkcja (7,4% rocznie), a znacznie wolniej konsumpcja, co skutkowało rozwojem eksportu. W latach 2001-2014 na rynki zagraniczne było kierowane 81% przyrostu produkcji, a w latach 2015-2019 - 99,3%. Rosnącemu eksportowi sprzyjają ceny mięsa. W latach 2014-2019 ceny drobiu na rynkach światowych były wyższe od cen w Polsce o 14,3%, a ceny w UE-27 wyższe od cen w Polsce o 51,7%. Do 2030 r. możliwy jest dalszy wzrost produkcji mięsa drobiowego w Polsce powodowany głównie popytem zagranicznym.","PeriodicalId":34485,"journal":{"name":"Zeszyty Naukowe Szkoly Glownej Gospodarstwa Wiejskiego w Warszawie Problemy Rolnictwa Swiatowego","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68311736","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}

Thus, examining information about consumers’ awareness on organic food is one of the inspiring areas for producers and marketers to capture a greater market share successfully. Therefore, this study aimed at analyzing the consumer awareness towards organic food products while addressing socio-demographic factors affecting consumer awareness on organic food, knowledge of consumers about organic food, and their purchasing pattern. A sample of 600 consumers was selected from the main cities of six urban districts in Sri Lanka for the study. Data were collected via a consumer survey using a pre-tested questionnaire, from November 2018 to May 2019. The data analysis was carried out using frequencies, percentages, and multiple linear regression analysis. According to the results, the majority of the respondents were married females. The results revealed that Sri Lankan consumers have a better awareness on organic food. The results of the regression analysis highlighted that the consumers’ awareness is significantly affected by factors such as gender, marital status, education, and monthly income. Although most respondents have a good level of awareness on organic food, their buying trend is at a lower level. The findings of the study play an important role in promoting the organic food market and are essential for food marketing planners, researchers, and policymakers to enhance the organic food industry in the country in the future.","PeriodicalId":34485,"journal":{"name":"Zeszyty Naukowe Szkoly Glownej Gospodarstwa Wiejskiego w Warszawie Problemy Rolnictwa Swiatowego","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68311668","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}

Therefore, the objectives of this study were: to understand the present situation of organic agriculture policies in Sri Lanka and also in other countries where successful organic agriculture is operating; identify problems in the organic agriculture sector; and suggest potential policy measures to be implemented in Sri Lanka in future. The research was conducted in two stages. In the first stage, a thorough literature review was conducted to study the suitable policies available in other countries and also in Sri Lanka at present. In the second stage, two field surveys were carried out using pre-tested questionnaires, from December 2019 to May 2020, in order to gather farmers’ and extension officers’ information related to organic farming policy suggestions. According to the findings of the literature review, organic systems in some countries are more integrated with national strategic plans and visions. Those governments are more involved in new initiatives and farmers are encouraged to go organic through reliable and feasible policies. Although Sri Lanka has a high potential for organic agriculture, at present it is at an initial stage. While most organic products in Sri Lanka go to the export market, a small portion is kept at local markets. Demand for organic products in export as well as domestic markets is increasing. Even though there are seven international food certification agencies operating in the country as external inspection and certification bodies, a limited number of accredited certifications exist for products on the domestic market. Results of the farmers’ survey showed that even if farmers have a significant level of knowledge, few of them practice organic farming due to several existing problems. Moreover, extension officers have also identified similar types of problems that are faced by the farmers related to organic farming. Evaluation of Strengths, Weaknesses, Opportunities and Threats (SWOT) related to organic agriculture in the country helped to identify key problems facing policy-makers when balancing the supply and demand sides of organic products. Also, in developing organic agriculture, an effective linkage and coordination among government and private participants is crucial. Therefore, in Sri Lanka in this context, strategic focus on policy support for organic agriculture is needed. Current organic farming programs need to be revised in order to formulate policies covering all areas related to production, handling, processing, certification, labeling and marketing, in order to bring the benefits of organic agriculture to farmers, marketers and consumers in a fair manner.","PeriodicalId":34485,"journal":{"name":"Zeszyty Naukowe Szkoly Glownej Gospodarstwa Wiejskiego w Warszawie Problemy Rolnictwa Swiatowego","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68311524","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 stages of participatory development were participatory need assessment, participatory stakeholders’ workshop and validation among 124 stakeholders selected as key informants in relation to agricultural extension training, delivery, end users and policy makers. The stakeholders were grouped as follows: community leaders and policy makers; extension agencies / organisations / institutions / employers; farmers; input suppliers / marketers / agro-based traders / other value actors; and potential candidate groups. Stakeholder meetings were held separately with different groups three times, and then a combined meeting took place. The aggregated major decisions/consensus were subjected to content analysis using ATLAS.ti. The validation process included reading of each agreed decision to all participants, then participants indicated their agreement or otherwise, which led to either rejection or acceptance of the decision. This paper concludes that participatory curriculum development has enhanced the stakeholders to identify areas of demand-driven training in response to community needs. The stakeholders preferred more online than face-to-face training. The major perceived advantages of e-extension were reduced risk, time and cost effectiveness while infrastructural and human challenges were the perceived challenges that could possibly hinder the smooth running of e extension.","PeriodicalId":34485,"journal":{"name":"Zeszyty Naukowe Szkoly Glownej Gospodarstwa Wiejskiego w Warszawie Problemy Rolnictwa Swiatowego","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68311480","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}

Today, about 10 million hectares of the world’s forest cover have been converted to other land uses. In Nigeria, there is an estimated increase of 8.75 million ha of cropland and decrease of about 1.71 million ha of forest cover between 1995 to 2020, indicating that Nigeria has been undergoing a wide range of land use and land cover changes. This paper analyses the changes in land use/cover in Ila Orangun, Southwestern, Nigeria from 1986 to 2018, with a view to providing adequate information on the pattern and trend of land use and land cover changes for proper monitoring and effective planning. The study utilized satellite images from Landsat 1986, 2002 and 2018. Remote sensing and Geographical Information System techniques as well as supervised image classification method were used to assess the magnitude of changes in the city over the study period. The results show that 26.36% of forest cover and 44.48% of waterbody were lost between the period of 1986 and 2018. There was a rapid increase in crop land by 365.7% and gradual increase in built-up areas by 103.85% at an annual rate of 3.25%. Forest was the only land cover type that recorded a constant reduction in areal extent. The study concluded that the changes in land use and land cover is a result of anthropogenic activities in the study area.","PeriodicalId":34485,"journal":{"name":"Zeszyty Naukowe Szkoly Glownej Gospodarstwa Wiejskiego w Warszawie Problemy Rolnictwa Swiatowego","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68311381","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}
