The paper provides an overview and a comparison of land markets covering the three candidate countries for European Union membership: Croatia, the Former Yugoslav Republic (FYR) of Macedonia and Turkey. We analyse and compare agricultural land structures and factors driving land markets. The analyses are based on the available crosssection and time-series evidence on agricultural land structure...
The purpose of this paper is to analyze the productivity change for agricultural cooperatives in Japan measured by nonparametric outputoriented Malmquist indices of total factor productivity. The productivity change is decomposed into technical change and technical efficiency change. Linear programming techniques are used to calculate the productivity change using a panel data set for 49 agricu...
The paper examines the structure and nature of cropping pattern, crop diversification, crop concentration, productivity level and inter-districts disparity in the state of Odisha based on the secondary data collected for the period 1980 – 2005 from different published sources. The study has used Herfindahl index, location quotient, Gini coefficient and panel data regression for analysis. The st...
In this study, considering the importance of incremental capital output ratio (ICOR) in agriculture Investment capital and self-sufficiency in this sector in order to grow and being influenced by the past and previous relationships strong agricultural sector productivity growth in other sectors of the economy, especially the effect of oil revenues, was trying to, long-term relationships as well...
Microbial communities drive biogeochemical cycles in agricultural areas by decomposing organic materials and converting essential nutrients. Organic amendments improve soil quality by increasing the load of essential nutrients and enhancing the productivity. Additionally, fresh water used for irrigation can affect soil quality of agricultural soils, mainly due to the presence of microbial conta...
An improvement and strengthening of agricultural infrastructure needed to all the levels of supply chain. Shrinking extension is another component of infrastructure that needs attention. After the green revolution in the mid-sixties there has been no major technological innovation, which could give a fresh impetus to agricultural productivity, insufficient extension services and poor access to ...
This study was undertaken to investigate the impact of microfinance on agricultural productivity by smallholder farmers in Makurdi Metropolis of Benue State, Nigeria. Data were randomly collected from 120 farmers consisting of 60 credit beneficiaries (CB) and 60 non-credit beneficiaries (NCB) by which were analyzed through descriptive statistics and multiple regression analysis. The results of ...

Agricultural practices have environmental impacts that affect a wide range of ecosystem services, including water quality, pollination, nutrient cycling, soil retention, carbon sequestration, and biodiversity conservation. In ...
This paper reviews the potential impacts of climate change on nitrate concentrations in groundwater of the UK using a Source-Pathway-Receptor framework. Changes in temperature, precipitation quantity and distribution, and atmospheric carbon dioxide concentrations will affect the agricultural nitrate source term through changes in both soil processes and agricultural productivity. Non-agricultur...
Photosynthesis is the process by which plants harvest sunlight to produce sugars from carbon dioxide and water. It is the primary source of energy for all life on Earth; hence it is important to understand how this process responds to climate change and human impact. However, model-based estimates of gross primary production (GPP, output from photosynthesis) are highly uncertain, in particular ...
