Abstract

Integrated farming system (IFS), comprising various enterprises such as crop, horticulture, dairy, poultry and fishery optimally, uses farm resources to suit small and medium farms of India. In this study, 55 IFSs with different sizes and several enterprises were assessed in terms of their environment impact, eco-efficiency and technical efficiency (TE). The households, which own these IFS, were grouped into four major categories based on farm size viz., marginal (<0.8 ha), small (0.8–1.2 ha), medium (1.2–2.0 ha) and large (>2.0 ha). Among the farm size category, the highest eco-efficiency was recorded for marginal farms, whereas the lowest eco-efficiency was observed for small farms. The highest eco-efficiency was recorded for farm having five enterprises (INR195 kg CO2eq. ha−1) followed by four enterprises (INR190 kg CO2eq.ha−1). Among the enterprises, the highest eco-efficiency was recorded in fruits, whereas the lowest eco-efficiency was observed in dairy. The TE scores estimated using stochastic frontier analysis decreased with increasing farm size and the highest TE score was recorded for marginal farms, whereas medium and large farms recorded the lowest TE scores. The findings indicated the necessity for imparting training and demonstrations and funding support as well as subsidy for larger adoption of IFS to reap higher returns.

印度东部不同综合农业系统的生态效率和技术效率

综合农业系统(IFS)由作物、园艺、乳制品、家禽和渔业等各种企业组成，最优地利用农场资源来适应印度的中小型农场。本研究以55间不同规模及多间企业的ifs为研究对象，就其环境影响、生态效率及技术效率(TE)进行评估。拥有这些IFS的家庭根据农场规模分为四大类，即边际(2.0公顷)。在农场规模类别中，边际农场的生态效率最高，而小农场的生态效率最低。拥有5家企业的农场(INR195 kg co2当量)的生态效率最高。ha−1)，其次是4家企业(INR190 kg CO2eq.ha−1)。其中，水果行业的生态效率最高，而乳制品行业的生态效率最低。使用随机前沿分析估计的TE得分随着农场规模的增加而降低，边缘农场的TE得分最高，而中型和大型农场的TE得分最低。调查结果表明，有必要提供培训和示范以及资金支持和补贴，以便更广泛地采用IFS以获得更高的回报。

期刊介绍： The International Journal of Agricultural Sustainability ( IJAS) is a cross-disciplinary, peer-reviewed journal dedicated to advancing the understanding of sustainability in agricultural and food systems. IJAS publishes both theoretical developments and critical appraisals of new evidence on what is not sustainable about current or past agricultural and food systems, as well as on transitions towards agricultural and rural sustainability at farm, community, regional, national and international levels, and through food supply chains. It is committed to clear and consistent use of language and logic, and the use of appropriate evidence to substantiate empirical statements. IJAS increases knowledge on what technologies and processes are contributing to agricultural sustainability, what policies, institutions and economic structures are preventing or promoting sustainability, and what relevant lessons should be learned.
