Soil organic carbon is affected by organic amendments, conservation tillage, and cover cropping in organic farming systems: A meta-analysis

, 2021
Meta-analysis is often used to compare how soil health differs between organic and conventional farming systems. However, the burgeoning primary literature on organic farming now allows direct evaluation of the best management practices (BMPs) within ...

Comparison of vegetable production, resource-use efficiency and environmental performance of high-technology and conventional farming systems for urban agriculture in the tropical city of Singapore.

Science of the Total Environment, 2021
Urban farming can improve cities' food security and resilience, but the performance of different farming systems with respect to land and investment constraints has not been systematically investigated.

A Generic Farming System Simulator

2009
The aim of this chapter is to present a bio-economic modelling framework established to provide insight into the complex nature of agricultural systems and to assess the impacts of agricultural and environmental policies and technological innovations. This framework consists of a Farm System Simulator (FSSIM) using mathematical programming that can be ...

Evolution of farming systems and system philosophy

Systems Research and Behavioral Science, 1999
Farming systems (FSs), and ways of thinking about them, evolved in space and time. Rapid evolution took place in the last two decades when crop and livestock yields increased, together with concerns about their socio-economic and biophysical tradeoffs.

The Farming System

2021
There are two millet varieties cultivated in Kala, a long-cycle bush field, and a short-cycle village field variety, covering more than 90% of farmed land. The characteristics, scale and access to land, labour and capital are presented, showing the very high reliance on household-owned resources.

Optimising Farm Plans in Different Farming Systems

Agricultural Economics Research Review, 2007
This study has been conducted to optimize farm plans in different farming systems in Orathanadu block of the Thanjavur district in Tamil Nadu by randomly selecting 150 livestock farmers from 6 villages. A linear programming (LP) model has been developed to arrive at the optimal farm plans for different categories of farms (landless, marginal, small and

A framework to assess the economic vulnerability of farming systems: Application to mixed crop-livestock systems

Agricultural Systems, 2019
The main challenge for farmers is to maintain a high annual income within an ever-changing context of production (climate, prices, sanitation issues), i.e. to ensure low vulnerability. The vulnerability of a given system corresponds to its susceptibility

Optimization of Farming Systems on Tribal Farms in Uttarakhand

Indian Journal of Economics and Development, 2015
The linear programming technique was used to examine the potentiality to increase the farm income. Across the farming systems, potential to increase Return Over Variable Cost (ROVC) over existing plan was highest in Farming System (FS)-IV (Livestock) followed by FS-I (Crop+Livestock) and FS-II (Crop).

Designing agroecological farming systems with farmers: A review

Agricultural Systems, 2018
Agroecology is a new paradigm whose aim is to redesign farming systems. The implementation of its principles engages farmers in a radical transformation of their practices, their way of reasoning and their participation in local knowledge production and ...
