Energy, economic, and environmental (3E) assessment of the major greenhouse crops: MFCA-LCA approach.

In order to develop sustainable production of greenhouse crops, the economic, energy, and environmental aspects of production should be considered. The purpose of this study was to evaluate the economic, energy, and environmental (3E) sustainability of cucumber, tomato, and bell pepper production in greenhouses by performing material flow cost accounting (MFCA) and life cycle assessment (LCA) material and methods. Calculating the economic and energy value of losses in agricultural sustainability assessment studies is not common. Using the LCA method alone does not allow us to calculate the monetary and energy value of waste. If this method is used simultaneously with MFCA, this gap will be filled. The system boundary for LCA was from cradle to farm, and for MFCA, foreground processes were considered. The production of each crop was compared at the level of 1000 m2 during 1year. Data were collected through questionnaire-based interviews. The gross value of production for cucumber, tomato, and bell pepper were 8982, 16387, and 17610 $/1000 m2, respectively. The negative production of cucumber, tomato, and bell pepper were 702, 718, and 449 $/1000 m2, respectively. The benefit-to-cost ratio in the production of cucumber, tomato, and bell pepper was calculated as 2.8, 5.17, and 5.8, respectively. The economic productivity in the production of cucumber, tomato, and bell pepper was calculated at 10.25, 7, and 4.4kg/$. Labor cost was the main cost in the production of all three crops. The total input energy for the production of cucumber, tomato, and bell pepper was estimated to be 99.4, 123.1, and 164.6 GJ/1000 m2, respectively. Negative products in the production of cucumber, tomato, and bell pepper were obtained at - 24.2, - 23.9, and - 13.5 GJ/1000 m2, respectively. The energy productivity of cucumber, tomato, and bell pepper was calculated as 0.23, 0.26, and 0.08kg/MJ, respectively. The specific energy indices were 4.32, 3.79, and 12.20MJ/kg for cucumber, tomato, and bell pepper, respectively. The energy ratio in the production of tomato (0.02) was higher than bell pepper (- 0.02) and cucumber (- 0.06). From the perspective of energy, electricity was recognized as the hotspot for the production of three crops. Global warming (GWP100a), ozone layer depletion (ODP), acidification (AC), and eutrophication (EP) indices were calculated for all three crops. Tomato production was ranked first in all impact categories. On-farm emissions and electricity consumption were identified as environmental hotspots. The subsidized price of electricity, natural gas, and chemical fertilizers has led to their excessive use in the production of greenhouse plants. It can be concluded that bell pepper has the best performance from an economic point of view. However, its production is not justified in terms of energy. Tomato was ranked first in terms of energy, and cucumber was ranked first in terms of low environmental impacts. The production of these plants with energy and chemical fertilizer subsidies is currently cost-effective. If the prices are corrected, the production of these plants will face serious challenges. Producing electricity from sunlight and mechanizing production processes can be a solution to these challenges.

Rural credit distribution in Bahia in 2017

Rural credit is an important tool for the country's economic development, and its objective is to promote rural development and increase agricultural production. However, credit distribution is uneven, favoring some regions over others. In Bahia it is no different. The objective of the present work is to evaluate and measure the distribution of rural credit in Bahia – the largest agricultural producer in the Northeast region – from the year of 2017. For this, tabular analysis, the entropy index and Theil's T and L indexes were used, as well as the redundancy index to measure the distribution of rural credit with the gross value of production as a productive counterpart. The results of the tabular analysis showed that there is a concentration of credit among the mesoregions of Bahia, an aspect that is less intense when verified by the T and L indices. When analyzing the distribution of credit and its productive counterpart, there was no concentration of credit distribution in the mesoregions bahians.

Agricultural eco-efficiency and water footprint- A case study of fifteen crops in the Chupaca province of Peru

The water footprint is an indicator of the impact of water use from its formation to its final destination. Agricultural eco-efficiency measures the efficient use of resources or materials available for crop production. Water's economic productivity analyses a product's efficient value as per its water supply and commercial value. The present research aimed to determine and relate the water footprint, economic productivity of water and agricultural eco-efficiency of 15 crops in the province of Chupaca - Peru. Georeferencing material was used for the delimitation of agricultural species, CROPWAT 8.0, CLIMWAT8.0, ArcGis 10.5 software, mathematical equations for the water footprint, agricultural eco-efficiency (Data Envelopment Analysis (DEA)) and economic productivity of water. The Total water footprint (TWF) of the fifteen crops was 1718237.01 m3/ton, likewise the BlueWF > GreenWF > GreyWF. In their economic outputs, gross value of production (GVP) > agricultural production (Ag-p) > economic rent agricultural (ERA) was verified. In environmental costs, water consumption that meets the needs of crops (Wc-Ag) > consumption of phytosanitary products (C-fly) > fertilizer consumption (C-fe) was determined. The average Agricultural eco-efficiency (Ag-Eec) and Economic water productivity (Ewp) were 89.8% and 0.046 PEN/m3 respectively. Statistical analysis between Ewp and Ag-Eec was rho = 0.18, t-test = 0.66 < 2.16 (α = 0.05; bilateral), and the correlation indicated that both activities are independent. The environmental costs and economic outputs of agricultural eco-efficiency did not influence the economic value of water.

Eco-efficiency analysis of rainfed and irrigated maize systems in Bosnia and Herzegovina

Abstract This study evaluated the eco-efficiency of rainfed and irrigated maize production in Bosnia and Herzegovina. Environmental impact assessments were performed through energy, carbon footprint, and water scarcity footprint analysis. For economic analysis, gross and net returns and benefit–cost ratios were calculated. Eco-efficiency was measured by the ratio between the net return and environmental criteria. The findings indicate that the transition from rainfed to irrigated maize cultivation per unit of land results in a 53.7% higher yield and gross value of production, but also a 69.8% increase in energy input, a 22% rise in greenhouse gas emissions, and a 3.6-fold increase in the water scarcity footprint. While a positive link exists in irrigated maize between higher yield and lower carbon footprint per unit of product, rainfed systems outperform in energy efficiency, productivity, profitability, water scarcity footprint, and overall eco-efficiency. Both systems rely heavily on nonrenewable energy sources, with fertilization (affecting energy and carbon footprint), mechanization (affecting carbon footprint), and irrigation (exacerbating water scarcity) as the main contributors to the negative environmental impacts. The implementation of optimization strategies for these inputs is of paramount importance to reduce environmental impacts and promote sustainability in maize farming in Bosnia and Herzegovina.

WOOD-BASED MARKET IN RIO GRANDE DO NORTE BETWEEN 1999 AND 2019

The objective of this work was to analyze the firewood, charcoal and roundwood market in the state of Rio Grande do Norte (RN) in the period 1999-2019. Data provided by the Brazilian Institute of Geography and Statistics (IBGE) were used referring to the quantity produced, unit value (UV) and gross production value (GPV), subdivided according to Agreste, Central, East and West mesoregions in RN. These variables were simplified in the form of descriptive statistics, with the UV and GPV deflated with a base year of 1999. In addition, the exploration products, the total area explored, the type of cut and the situation regarding the plans of sustainable forest management - PMFS, were analyzed, as provided by the Northeastern Plant Information Center (Centro Nordestino de Informações Sobre Plantas, CNIP). The results generated allowed us note that the West mesoregion stood out in the production of firewood, being the second largest producer of charcoal and the only producer of roundwood logs. The highest UV per ton of coal occurred in 2016 in the Agreste and West mesoregions; in 2018, in the Central mesoregion and, in 2013, in the East. The highest UV per cubic meter of firewood occurred in 2017 for the Agreste and Central regions, and in 2019, in the East and West mesoregions, respectively. The Central mesoregion had the highest number of PMFS in the state, with most of the plans that are currently active being used for the exploitation of firewood. West mesoregion presented only two assets.

Profitability and Cost Analysis for Contract Broiler Production in Turkey

This study uses the data obtained from 63 broiler farms engaged in contract farming in Akhisar, Turkey. The average feed conversion ratio in the broiler farms is 1.75, the average live weight 2.25 kg, and the mean market age 38.9 days. The feed conversion rate and the income generated are highly correlated (r = −0.76). The production index is 313.4. According to this production index value, 47.6% of the enterprises are below the average production index. It is highest when the marketing age is greater than 38 days, less than and equal to 40. In other words, it is the optimum market age range where carcass yield is at maximum. The average mortality rate is 4.68%. In 52.4% of the enterprises, the mortality rate is above 5%. There is a low level of correlation between the mortality rate and income (r = −0.26). In broiler farming, mortality rate, and feed conversion ratio are factors that directly affect the success and income of the breeder. In broiler farming, the heating cost has the largest share of the total cost, followed by the litter cost. They are followed by labor, electricity, and pesticide costs. Variable costs account for three-quarters of the total operating costs. The farms have a mean gross value of production of $23.797 per m2 and $1.400 per broiler in a breeding period. The profit margin is 0.572 $/kg per broiler. The mean enterprise net income in the breeding period is $9.197 per m2 and $0.541 per broiler. These findings suggest that broiler farming is a profitable venture.

Contribuição financeira por grupo de produtos agropecuários dos municípios paulistas em relação à área produtiva ocupada.

Differences in agricultural productivity may not be clearly detected with the politicaladministrative division constituted by adjacent areas of municipalities. The objective of this work was to identify the productivity of rural areas, with productive activity, in groups of agricultural products in the municipalities of the state of São Paulo. It involved variables on the gross value of production and types of use in rural areas. Production in municipalities was concentrated in certain sets of products, with productive diversification not occurring in municipalities, but in clusters of municipalities and more sharply in regions with higher productivity.

The Effects of Different Tillage Techniques on the Production Costs in Fallow-Wheat Rotation System

The adoption and applicability of the technologies developed in agriculture by farmers are very important for agronomic studies. There are a limited number of economic studies comparing different tillage methods with each other. This study was conducted in the land of Polatlı Agricultural Enterprise between 2011 and 2017 to determine the amounts of physical production inputs and unit production costs of three different tillage operations in the fallow-wheat rotation system. The data consist of the production inputs in the Conventional Tillage, Minimum Tillage, and Direct Seeding practices. For the economic analysis, Single Product Budget Analysis was used. All the farmers’ production costs in the fallow-wheat rotation system were considered in the analysis. Among the practices, Gross Production Value (GPV) was obtained the most from the (509.63$ ha-1) practice. This practice was followed by Direct Seeding (486.13$ ha-1) and Minimum Tillage (421.92$ ha-1) practices, respectively. The profit threshold was exceeded in all practices, and production activities’ variable and total costs were fulfilled. The highest relative profit rate was obtained in Direct Seeding (1.77) practice, and it was followed by Conventional Tillage (1.30) and Minimum Tillage (1.08) practices, respectively. In order to obtain an income of $1 in wheat production, the lowest production cost was obtained in the Direct Seeding practice. With the Direct Seeding application, it can be ensured that economic wheat production, preservation of soil structure, reduction of input costs, and less economic damage to the farmer in changing climate conditions can be achieved.

Somatic Embryogenesis in Banana (Musa spp.).

Bananas (Musa ssp.) are among the world's most important crops. In terms of gross value of production, they are the fourth most important global food crop and have an important socioeconomic and ecological role. Somatic embryogenesis (SE) is a developmental process, in which somatic cells differentiate into embryos which eventually develop and regenerate into plants. SE is exploited to generate a large quantity of very high economic value, genetically identical and disease-free plantlets. In bananas, the use of shoot apexes of axillary buds to induce SE resulted an alternative for plant regeneration through embryogenic cell suspension (ECS). The protocol has been scaled up to commercial laboratories for tissue culture (biofactories) for production of planting materials. The genetic stability of regenerated plants and high yields obtained under field conditions demonstrate the feasibility of scaling up this biotechnological protocol and adapting it to commercial production of planting materials to mitigate a critical bottleneck in the value chain of this important crop.

ROLE OF ROOT FEEDING IN MODERN TECHNOLOGY OF CULTIVATING GRAIN CORN

The article presents the results of studying the impact of foliar fertilization with Ekolist Mono Zinc microfertilizer on the complex of economically valuable traits and productivity of maize hybrids of different maturity groups. The research has been conducted for studying the dependence of the timing of foliar fertilization on the level of productivity of corn. Field research was established during 2019-2020 in the research field of the Department of Plant Breeding, Breeding and Bioenergy Crops of SE "Kordelivske" IC NAANU Vinnytsia National Agrarian University. The soil of the experimental site - dark gray is characterized by the following agrochemical parameters: humus content - 3.27%, nitrogen supply (by the method of Cornfield) low - 116 mg / kg of soil, mobile phosphorus compounds (by Chyrykov method) average - 95 mg / kg of soil , and high potassium - 137 mg / kg of soil, pH - 6.5. A two-factor experiment with corn was established by the method of split plots. The study was performed in quadruplicate. The sown area of the plot is 50 m2, the accounting area is 25 m2. Observations and crop accounting were performed according to generally accepted methods. Studies have shown that the largest increase in plant height (11-18 cm) and the height of attachment of cobs was observed in variants with two foliar feeding of corn with microfertilizer Ecolist Mono Zinc. Application of Ekolist Mono Zinc microfertilizer in the phase of 5-7 and 10-12 corn leaves provides the highest value of cob length: DKS 2971 (FAO 200) - 22.0 cm, DKS 3476 (FAO 260) - 25.2 cm and DKS 3511 330) - 26.0 cm, increases the weight of 1000 grains by 7.5-12.4%, protein content by 0.07-0.15%, reduces the fat content by 0.01-0.20% compared with the control. The highest value of yield of the studied maize hybrids was obtained by double application of microfertilizer Ecolist Mono Zinc in the phase of 5-7 and 10-12 leaves of corn, and on average for two years it was: DKS 2971 (FAO 200) - 7.5 t / ha, DKS 3476 (FAO 260) - 9.8 t / ha and DKS 3511 (FAO 330) - 10.4 t / ha, while the control yield was 6.6; 8.8 and 9.0 t / ha, respectively. Taking into consideration the results of the analysis of economic indicators of cultivation of maize hybrid DKS 3511 (FAO 330), the highest value of gross production per 1 ha - 41.44 thousand UAH / ha - was obtained on the option with double application of microfertilizer Ecolist Mono Zinc in phase 5-7 and 10-12 leaves of corn, the lowest cost of grain is set - 156.5 UAH / c. The final indicator of economic efficiency - the level of profitability - was the highest and amounted to 254.5%. Thus, foliar fertilization increases the yield of maize hybrids of different maturity groups, improves the quality of grain in terms of chemical composition and optimizes the value of economically valuable traits.

Economic impacts of chickpea grain classification: how ‘seed quality is Queen’ must be considered alongside ‘yield is King’ to provide a princely income for farmers

Chickpeas (Cicer arietinum L.) are a high value crop for farmers, but price penalties will be imposed or grain rejected whenever the standards are not met by growers whose crops suffer grain defects in a particular season. Australian chickpeas are renowned for their high quality and are generally in high demand globally because of good farming practice and strict grain quality standards. However, small quantities of defective seed in grain loads can reduce the price paid to individual farmers, with significant financial impacts. Information is scarce on the types of defects causing price penalties and there is no information on the magnitude of those penalties. An online farmer survey was conducted to capture information on the types of grain defects, price penalties imposed and load rejections with respect to the delivery of their 2017 chickpea crop. Here we show that the cost to individual chickpea farmers affected by price penalties or load rejections ranged from AU$743 to $1293750. Furthermore, the total cost of seed defects was calculated to be $154.2 million in that season, equating to a revenue loss of 23.7% of gross value of production in Australia. Chickpea seed defects also contributed to additional costs including seed cleaning, further transport costs and harvest delays, with subsequent risk of yield losses and further quality defects. Too often, crop yields are the focus while seed quality is overlooked as an essential driver of farmer profitability. We demonstrate how important seed quality is to farmer profitability; if ‘yield is King’ then seed quality is certainly Queen. We suggest that farmers prioritise harvest of their chickpea crops ahead of harvest of cereal crops to minimise the risk of chickpea seed defects and seed loss, and to maximise profits from this higher value crop. Additional surveys over several seasons are warranted to refine information on the types of seed defects occurring in chickpea and their financial impacts on farmers, and they could be expanded to other crops and countries. We suggest that misclassification of seed defects needs further exploration, as does research into minimising the major causes of seed defects. Improvements to grain classification systems globally should be sought to provide better support for farmer profitability so that they can continue to feed the world.

Atividade leiteira no Paraná: uma análise espacial e econométrica

O presente estudo buscou verificar a configuração espacial da produção de leite nos municípios do Paraná. Foi realizada uma Análise Exploratória de Dados Espaciais – AEDE, que possibilitou identificar a existência de clusters espaciais nas mesorregiões Oeste, Sudoeste, Centro Oriental e Norte Pioneiro. Isso mostra que municípios que possuem alto valor do Valor Bruto de Produção (VBP) do leite (reais/Km2) no Paraná são rodeados por municípios de similar alto valor do VBP do leite (reais/Km2), assim como municípios com baixos valores para a variável. Utilizando os dados preliminares do Censo Agropecuário 2017, da RAIS e do IPARDES estimou-se um modelo econométrico, do tipo Durbin Espacial (SDM), que inclui a defasagem espacial no valor bruto de produção e nas variáveis independentes, a fim de identificar quais, dentre fatores econômicos e técnicos, são os determinantes do valor bruto de produção de leite. Como principais resultados observou-se que a orientação técnica, produtividade, pastagem, ocupações técnico-científicas e energia elétrica são alguns dos fatores que estão associados ao valor bruto de produção do leite.

INDUSTRIAL TOMATO FOR FRESH CONSUMPTION: A TECHNICAL AND ECONOMICALLY VIABLE ALTERNATIVE

The cultivation of hybrid tomatoes, intended for fresh consumption, with a determined growth habit, and without support, is an alternative that has a lower production cost. The research aimed to evaluate the productivity and economic viability of different tomato genotypes, with a determinate and indeterminate growth habit. The experimental design was in completely randomized blocks. Ten hybrids and a variety were grown in 2016, and nine hybrids, and a variety in 2018, with a spacing of 0.5 meters between plants. Harvests were carried out in four periods in 2016, at 72, 82, 97, and 105 days after transplanting (DAT); and in 2018 at 81, 87, 97, and 111 DAT. After harvesting, the gross value of production and profit were quantified. The hybrids that obtained the highest production per plant in 2016 were Gabrielle (6,010 kg), with support; Thaise (5.529 kg); and N901 (5.003 kg). In 2018, Dominador and Thaise hybrids had the highest production, with 4.109 and 3.961 kg per plant, respectively. The gross value of tomato production in 2016 was higher than in 2018 for all hybrids and variety, except for Dominador hybrid. Hybrids with a determined growth habit and conducted without support are a profitable alternative to produce tomatoes intended for fresh consumption, especially the hybrid Gabrielle, which had the highest production. The economic viability of hybrids grown without support is superior to all hybrids with support.

It should be ensured that enterprises use their resources effectively. Information meetings should be held for enterprises on resource use.

Choosing Fit for Purpose Open Source AgTech Innovations on a Large Broadacre Mixed Farming Enterprise in Western Australia

This is the second of a six paper series on farmer AgTech adoption in the WA grains industry that use open source information technology devices to solve for production problems that increase productivity. The first five papers are case studies outlining the business drivers of the adoption of differing types of AgTech adoption. A key proposition under investigation is that the particular circumstances of a farm implies that each farm will have a different path of open source information technology adoption that will give it the best risk adjusted rate of return. They consider the variables of farm scale (three are at or above minimum efficient scale – MES – for cropping), enterprise mix (three are mixed farm operations), rainfall zone and management structure/depth and group vs. single farmer adoption. The sixth paper is a summary document of key themes, – including the interaction of adoption with on and off farm connectivity and data integration – and public policy implications. It will discuss private and public structural and strategic options to deal with connectivity and complexity issues that are necessary for WA agriculture to access the productivity gains possible from adopting the full suite of available technologies. This case is similar to the first case in that: both are of a similar size (~10,000 ha); both farm on the edge of the low and medium rainfall zones; both are at least minimum efficient scale in grain production (or ‘one tractor size’ or ‘unitisation scale’; that is a minimum of 4,000 ha); both have sufficient financial resources to deal with the cost of initial investment; and both have management structures to permit the business development needed to deal with the inherent complexity associated with adopting a new technology. However, the Newmans’ farm is a discontinuous mixed operation of grains and sheep spread over several properties. The farm places its premium on monitoring data largely pertinent to livestock production because this generates the best rate of (risk adjusted) return for it. Typical of most WA broadacre farms, connectivity to the Newman’s farm is poor. Much of the farm does not have mobile coverage or frequently drops out and the NBN satellite service is slow, intermittent and expensive. Consequently, the Newmans have invested to create an internal farm connectivity backbone onto which open source technology devices are attached to solve production problems. They have also invested in farm to mobile tower connectivity; further investment to automatically connect to the existing satellite NBN connection in case of mobile tower failure is in progress. The rate of return from these investments is high, reflecting significant productivity gains. Modelling by Perret et al (2017) for the Cotton CRC indicates that very large productivity and Gross Value of Production gains can be made by the full adoption of decision/precision agriculture. A key issue running through these papers is how are farms able to begin the journey of adopting such technologies? CSRIO’s ADOPT framework is used to outline the observed patterns of farmer adoption of new technologies. The Newmans’ adopted AgTech technologies are easily trialed, easily reversed, comparatively low cost, and because of the farm’s management structures and financial resources, they are able to be absorbed into existing production without greatly increasing complexity. The pertinent question is whether the expense and complexity of establishing this type of system implies a significant barrier to entry for farmers without the required financial resources and management structures. This theme will be further explored in subsequent case studies.

Regional Concentration of The Gross Production Value of Firewood in Paraíba

ABSTRACT This study analyzed the regional concentration of the gross production value (GPV) of firewood in Paraiba from 1994 to 2014. It measured the concentration by means of the Concentration Ratio [CR(k)] of the Herfindahl-Hirschman Index (HHI), Theil’s Entropy (E), the Hall-Tindelman Index (HTI), and the Gini Index (G). From the analyses performed, it was concluded that there was growth in the GPV of firewood in Paraiba from R$ 2.59 million to R$ 10.39 million (in current terms). The CR(4) and CR(8) of the municipalities indicated low concentration; the CR(4) in the microregions presented a moderately low concentration, and the CR(8) had moderately high concentration. The HHI of the municipalities and microregions has a competitive market, and the HHI of the mesoregions has moderate concentration; E corroborated the evidence of HHI; HTI presented low regional concentration; G showed medium to strong inequality for mesoregions, weak to medium in microregions and zero to weak in municipalities.

Eurointegration aspects of meat production in agricultural enterprises of Ukraine: problems and prospects

European integration processes have become an indispensable feature and direction of development of meat cattle breeding in Ukraine. To calculate the forecast value of gross production of livestock products, we have chosen a method based on the construction of mathematical statistical models. Forecast indicators of cattle livestock in agricultural enterprises of Ukraine are calculated by constructing a polynomial trend line, since the equation of this model has the highest correlation and determination coefficients (0.980051 and 0.9605 respectively), that is, it describes a number of dynamics most reliably. The polynomial trend model is described by the following equation: y = 35.134x2 – 1704.8x + 20748. According to the results of calculations in 2025, the achievement of the cattle population is projected at 2.243.7 thousand heads. The dynamics of the pig population also reflects the polynomial trend model described by the following equation: y = 19.638x2 – 812.86x + 10803, the correlation and determination coefficients of 0.885268 and 0.77837, respectively. In case of preservation of the current tendency, in 2025 the pig population in agricultural enterprises of Ukraine is expected to grow to 5011.2 thousand head, which is 38% more than in 2017. Based on the calculations (polynominal trend y = 148.43x2 – 2542.8x + 72000, the coefficients of correlation and determination are 0.808084 and 0.653), we forecast that in 2025 in agricultural enterprises of Ukraine, the number of all species of poultry will reach 153019,1 thousand heads. This is 1.4 times more than in 2017. According to our calculations (polynomial trend y = 3.013x2 – 134.03x1489.4, correlation coefficients and determination coefficients (0.95734 and 0.9165 respectively), the production of beef and veal in Ukraine in the coming years will gradually increase, despite decreasing volumes Due to the use of modern technologies and increased production intensification, we predict that in 2025 agricultural enterprises of Ukraine will produce 606.8 tons of pork, which is 50.1% more than in 2017. However, paying attention to the projected volumes of pork production, it should be borne in mind that agrarian production in general and pig production in particular are oriented towards market demand, therefore, its efficiency depends on the competitiveness on the domestic and foreign markets. The increased demand for poultry meat stimulates an increase in its volumes on an industrial basis, first of all, the production of broilers, as speedy and high-yielding poultry. According to our calculations (polynominal trend y = 2.1386x2 – 19.579x + 144.8, correlation coefficients and determination (0.985089 and 0.9704 respectively), using modern means of mechanization and automation of technological processes at low labor costs and facilities per unit of production, commodity producers will be able to produce in 2025 р. 2270,5 thousand. tons of poultry meat. In our opinion, the advantages of integrating meat poultry farming into the European Union are complicated by requirements and restrictions and create additional incentives for the development and improvement of production.

SPATIAL DISTRIBUTION OF FIREWOOD PRODUCTION IN NORTHEASTERN BRAZIL (1994-2013)

ABSTRACT This paper analyzed the effects of the spatial distribution of the firewood gross production value (GPV) of northeast Brazil through an exploratory approach using spatial data for the period from 1994 to 2013. Identification of spatial clusters in firewood production through the spatial weighting matrices of 2 nearest neighbors and “queen” and “rook” contiguity matrices were used. Based on the analyses, the following can be concluded: there is a positive autocorrelation for firewood GPV; the high-high spatial cluster was formed predominantly in the Bahia region; the high-high spatial cluster, which considers the weight matrix per area, was composed of the Ceará and Pernambuco mesoregions; the low-low spatial cluster consisted of the Sergipe and Alagoas mesoregions; and the low-low cluster, which considers the weight matrix per area, was formed by the Sergipe, Alagoas and Piauí regions.

Rentabilidade econômica de propriedades rurais em Paragominas (PA) com o suporte de geoprocessamento

A dinâmica produtiva do setor agropecuário promove a criação de empregos/ocupações em suas várias atividades, tanto nos segmentos ligados à agricultura, quanto nos inerentes à pecuária. Paragominas, município localizado na mesorregião do nordeste do estado do Pará, destaca-se quanto ao seu crescimento no setor agropecuário, mantendo vigoroso crescimento econômico e melhora nos indicadores sociais, o que pode ser resultado de uma combinação de investimentos na intensificação do uso da terra. Portanto, o objetivo deste estudo é analisar a rentabilidade, levando em consideração a área do imóvel rural e o valor bruto de produção (VBP), oriundo das diferentes classes produtivas do setor agrícola no município. Para a realização deste trabalho, utilizou-se informações vetoriais e trabalhos de campo em 143 propriedades. Os principais tipos de atividade produtiva considerados foram os que obtiveram um valor de produção mais significativo que as demais. As propriedades rurais analisadas têm sua produção majoritária distribuída em oito classes, que são: criação de animais de pequeno, médio e grande porte; cultura permanente e temporária; horticultura e extração madeireira e não madeireira, que juntas somam um VBP de R$51.708.600,00. Dessas classes, a criação de animais de grande porte foi a que obteve maior predominância, ocupando 48% do total de propriedades, sendo a pecuária a atividade que mais se destacou nessa classe. A criação de animais de pequeno porte foi a que obteve a maior rentabilidade e uma das menores áreas. Outra classe que obteve alta rentabilidade foi a criação de animais de médio porte. Podemos notar que as duas classes de produção que necessitam das menores áreas foram as que obtiveram a maior rentabilidade, pois sua produção é adensada. Desse modo, observa-se a importância de estudos a respeito da eficiência e sustentabilidade das atividades rurais, devido a diversidade de atividades desenvolvidas, bem como, a rotatividade econômica advinda da produção rural. Espera-se que cada propriedade cumpra sua função social, assim, contribuindo para a geração de renda local e servindo de base para estudos que visam o melhor conhecimento das ocupações na região Amazônica.
