Written by Cristina STANCĂ-MOISE

The impact on forest ecosystems caused by insect has two components, one ecological and one socio-economical. Ecological component relates to the effects of environmental parameters overview of the stands, with direct results in time on individual trees, as on the other components of ecosystems. The socio-economical component of the impact shows how these effects influence the forest resources including the productive ones and the aesthetic recreational ones. While the socio-economic value is expressed in units of currency/unit area (euro/ha), the environmental impact can be expressed in terms like: modifying the composition stands, reducing density, reducing annual growth rate or period etc. Each of these two components of the impact can be treated after the effect of time on the ecosystem, namely: long or short. At the level of forest ecosystems, with a complexity and objectives of management different, the concept of short or long term, is quite relative, so that below will not be explicit reference to the mode of action in time of the defoliators effects but only on each component of the forest ecosystem.

Written by Zbigniew GOLAS

The main purpose of this work is to analyse the changes in work profitability in Polish agriculture. The analysis is based on the Economic Accounts for Agriculture, i.e. the applicable in the EU harmonised financial statement, which enables the analysis of the economic situation in agriculture according to uniform rules. The basis for the research have been the proposed systems of work profitability indicators and factor analysis (the logarithm method). The research has proven that in the post-accession period work profitability in agriculture increased in real terms on annual average by about 4,47%, and in 2013 in comparison to 2004, work profitability was higher in real terms by almost 60%. In the light of the factor analysis the main determinant of changes in work profitability in the domestic agriculture was the increase in work productivity and production subsidies.

Competition is necessary for enhanced customer welfare and efficiency. This study focused on marketing efficiency of packaged water in Imo state Nigeria. It specifically examined the socio-economic profile of the respondents; levels of marketing efficiency of packaged water and its determinants. The study employed purposive and multistage sampling technique in the selection of location and respondents respectively from whom information were elicited. Analytically, descriptive statistics, schematic diagram and OLS multiple regression models were used. Results showed that the respondents were predominantly married male adults, with average household size of 7 persons. They were fairly educated and experienced in the business. The study further revealed that age, education, household size and income were the major determinants of marketing efficiency of packaged water marketing in the area. The result also showed that net income, marketing cost, and marketing margin were higher in urban area, which implies that marketer in semi-urban areas were operating below optimum efficiency levels. This study therefore suggested the need to incorporate integrated logistics management and marketing strategies as a measure to reduce unnecessary marketing costs; capacity enhancement programmes for marketers and improvement in infrastructural development as a means of addressing marketing efficiency and customer welfare.

DETERMINANTS OF PALM OIL OUTPUT SUPPLY IN NIGERIA

Published in Scientific Papers. Series "Management, Economic Engineering in Agriculture and rural development", Vol. 15 ISSUE 4
Written by Chigozirim Ndubuisi ONWUSIRIBE, Chibuzo Ikechukwu OKPOKIRI

This study analyzed the determinants of palm oil output supply in Nigeria. A time series data, from the period of 1970-2014 were collected from the Food and Agricultural Organization data base and other sources. Trend analysis, ADF unit root test, co-integration test and error correction model were used to analyze the data. The trend in the output supply of palm oil shows significant growth rate based on the coefficient of the time trend (b1). The unit root test using Augmented Dickey Fuller test (ADF) shows that all the variables have constant mean except for palm oil yield which led to the Autoregressive Distributed Lag (ARDL) co-integration test which reveals the presence of long run relationship existing between the variables and short run relationships with error correction term. Imports of palm oil has negative significant short run and long run impacts on the output supply of palm oil while in the short run palm oil exports has a significant negative impact on the palm oil output supply and a significant positive impact in the long run. The error correction model (ECM) suggests a high speed of adjustment of the dependent variable to changes in the independent variables. The import of palm products affects the output supply of palm oil negatively as this impedes the local production of palm oil. Export of palm oil was positively signed indicating that export of palm oil encourages the farmers to increase their output supply. This study therefore, recommends the promotion of export and formulation of export promotion policies to stimulate international market for our palm oil and encourage our farmers to boost their output.

This study has it objectives as to describe the types of crops marketed by the women; to determine the factors that influence women participation in marketing of food crops in the study area and make recommendations based on the findings. A multi-stage sampling procedure was employed in the study. First, two Local Government Areas were selected from each of the three agricultural zones, this was followed by the random selection of twenty respondents from the selected Local Government Areas, bringing the total number of respondents to a hundred and twenty. Descriptive statistics and the probit model were used in analyzing the data collected from a set of questionnaire administered on the respondents selected. The results of the analysis showed that cassava, maize, water yam, sweet potatoes and cocoyam were the major food crops marketed by the women. The probit results indicate that age, experience, output, source of capital and source of labour were significant at different probability levels and with different signs. The study recommended that sources of income whether formal or informal sources should be made more accessible to women, amongst other things.

This paper determined women participation in livestock Production in Mangu local government area of Plateau State, Nigeria. Simple random sampling was used to select 90 women livestock farmers. Descriptive statistics, Participation Index and Multiple Regression Analysis were employed to analyse the data. The regression results revealed that extension contact was significant (p<0.01) and positive, while age and education (p<0.01) and years of experience (p<.0.05) were significant factors influencing women participation in livestock production although negative. Poultry, swine and goat production raked first, second and third respectively. The result further shows that the coefficient of multiple determinations (R2) was 0.554, this indicates that 55.4% of the variation in women participation is accounted for by the explanatory variables included in the model. The study recommends that the women should be more capacitated in terms of support through engaging them more meaningfully on economic activities of not only the family but in decision making on matters affecting women. Also the training need of women participation in livestock production should be identified and also soft capital should be provided at the affordable and right time.

This research analyzed determinants of women’s participation in self help group-led micro-financing of farms in Isuikwuato Local Government Area of Abia State, Nigeria. The specific objectives were to; determine the level of women’s participation in self help group led micro financing of farms; determine the factors that influence women’s participation in self help group micro financing of farms; identify constraints of women participation in self help group micro financing of farms in the study area. Multistage random sampling technique was employed in collecting data from one hundred and twenty (120) members of women self help group using structured questionnaire. The data were analyzed using descriptive statistics, likert scale type and probit regression analysis. The research revealed that the women (respondents) actively participated in self help group meetings ( = 3.07), financial and material contributions (= 3.33), self help group project (= 3.36) and recruitment of fresh members (= 3.16), because their calculated means were greater than the critical midpoint mean score (3.0). The study also showed that the women did not participate in committee membership ( = 2.54) and holding of official executive position (= 2.53) in self help group since the midpoint score (3.0) was greater than their calculated mean values. The result of probit regression analysis showed that women’s participation in self help group led micro financing of farms was influenced by household size, years of membership experience, access to credit, primary occupation, mode of entry and annual contribution. The model predicted 94.69 per cent of the sample correctly and posted a log likelihood value of -33.54958, a pseudo R2value of 0.3013 and a goodness of fit chi-square value of 32.10 which is statistically significant at 1.0% level. Meanwhile irregular monthly contribution and loan default were the major constraints of women’s participation in self help group led micro financing of farms. It was recommended that leadership positions within self help groups should be made to rotate among the broad spectrum of longer serving members. This will ensure greater commitment to group success and sustenance by a greater number of members.

DETERMINING THE NUMBER OF OCCUPIED PERSONS, NEEDED BY DAIRY CATTLE FARMS IN BULGARIA

Published in Scientific Papers. Series "Management, Economic Engineering in Agriculture and rural development", Vol. 16 ISSUE 4
Written by Tsvetana HARIZANOVA – METODIEVA, Nikola METODIEV

The aim of the study is to determine the number of occupied persons, needed by dairy cattle farms in Bulgaria. The information was collected through interview and the number of cows in the main herd, decares of arable land (own and rented) and the number of occupied persons, directly involved in the production process, were analyzed. A regression model was constructed with a confidence level of 95% using the Ordinary Least Squares Method. The regression model is as follows: L = C1.A + C2.D + C + a, where: L is natural logarithm of the the number of occupied persons, needed by dairy cattle farms; А is natural logarithm of the decares of arable land; D is natural logarithm of the number of dairy cows; C1 and C2 are the coefficients of the independent variables; С is a constant; a is an error of the regression. By replacing the constant and the coefficients with their theoretical values, it is obtained the following model: L = 0.067.A + 0.596.D - 1.386. The number of occupied persons could vary depending on the type of crops, the technology and the intensification of the production process. With the increase in the number of cows in the main herd and the amount of arable land, the number of occupied persons needed also increase. The constant in the regression model is a negative number (-1.386), which could be explained by better utilization of the working time: a major part of the occupied persons can perform activities related to dairy farming, and can also be included in forage production. It could be concluded that for a farm with 20 cows and 20 decares of arable land, the theoretical number of occupied persons is 1.8. A farm with 100 cows and 100 decares of arable land needs an average of 5.3 workers, but the number can vary between 3.8 and 6.8 workers. In a farm with 150 dairy cows and 3,000 decares of arable land needs an average of 8.5 workers. The combination of forage production and dairy cattle production leads to optimization of the number of occupied persons needed.

DEVELOPMENT OF IMPLEMENTATION OF AGRICULTURAL INSURANCE IN TURKEY

Published in Scientific Papers. Series "Management, Economic Engineering in Agriculture and rural development", Vol. 17 ISSUE 2
Written by Ayse TEKIN, Bahri KARLI, Mevlut GUL

The share of the agricultural sector in employment in Turkey is 23%. Turkey is among the world's leading countries in the production of many agricultural products. In this respect, it has a great potential in terms of agricultural insurance. In 2005, in Turkey, "Law on Agricultural Insurances" was enacted with the law numbered 5363. In this 10-year period, premium production was realized as 5 billion Turkish Liras. The total number of farmers who have insurance in Turkey reached 2,031,061 in 2016 and the 316,000 damage file has been processed, 900 million Turkish liras were paid to the producers. In case producers have to insure agricultural insurance, the price they will pay per decare is 330 TL. These farmers will be able to pay close to 10 thousand Turkish liras in case of damage to their land. In this study, it was aimed to examine the agricultural insurance schemes existing in Turkey, the agriculture insurance pool system and the 10 years development under the law numbered 5363. In this context, the development of plant life, animal life, greenhouse, beekeeping, poultry life and aquaculture life insurance was examined. Proposals were developed for the producers to benefit more from agricultural insurance premium subsidies. Findings obtained from other studies related to the subject were also examined. In insurance premium subsidies, the innovations and objectives of the year 2017 implementations were also mentioned. In this system, 50% and/or 66.7% of the insurance premium is covered by the government as unrequited support. In total premium production in Turkey, there is a plant product insurance with a share of 28.0% at the maximum and an animal life insurance with a share of 20.8% in the second. The number of policies and insurance premiums increased by 27% and 32% respectively in 2015 compared to the previous year in Turkey. As of December 30, 2016, total premium production in Turkey has reached TL 1.3 billion. As of 2016, 2 million 470 hectares of land belonging to 562 thousand farms in 72 provinces were damaged from natural disasters. However, it is noteworthy that the ratio of insured farmers was between 10-20%. Therefore, it is necessary to increase the producers' regularly insured agricultural insurance rates. In this regard, actions are being proposed to increase awareness of more producers. In this way, there may be a minimum loss of producer income in the agricultural sector where risk and uncertainty are high.
