While modern agriculture relies on genetic homogeneity, diversifying practices associated with seed exchange and seed recycling may allow crops to adapt to their environment. This socio-genetic model is an original experimental evolution design referred to as on-farm dynamic management of crop diversity. Investigating such model can help in understanding how evolutionary mechanisms shape crop d...

Conservation agriculture (CA) systems are based uponminimal soil disturbance; crop residue retention and crop rotation and/or intercrop association are increasingly seen to recycle nutrients, increase yield and reduce production costs. This study examines the effects of CA practices on crop productivity, profitability and soil quality under the conditions encountered by smallholder farmers in t...

The enactment of agricultural system is most vital for India as it is the land of agriculture. Agriculture is related to the Latin term “Ager” and “Cultura”. This paper focuses on the development of a agriculture system for farmers using MATLAB. The GA technique is used to evolve farming techniques for maximizing benefits in Uttar Pradesh. The main objective of development is to provide better ...

This study investigated the information needs of cotton growers residing in two villages in the district of Bahawalpur. Face-toface interviews were conducted by visiting farms or homes using a semi-structured interview schedule. Data were analyzed by applying descriptive statistics. The results indicated that cotton growers required information, in general, in the areas of soil management and p...

A model that integrates biophysical simulations in an economic model is used to analyze the impact of climate change on crop production. The biophysical model simulates future plantmanagement-climate relationships and the economic model simulates farmers’ adaptation actions to climate change using a nonlinear programming approach. Beyond the development of average yields, special attention is d...

Nepal is small geographically, but is an important centre of agricultural biodiversity. The rich Nepalese agro-biodiversity has evolved over time and space due to extreme variations in altitude and environmental conditions. Crop production takes place between 70 to 3000 m elevation where a wide range of micro-ecological niches are found, and varied crop production systems are being practiced by...

Considering how people perceive risks to their livelihoods from local wildlife is central to (i) understanding the impact of crop damage by animals on local people and (ii) recognising how this influences their interactions with, and attitudes towards, wildlife. Participatory risk mapping (PRM) is a simple, analytical tool that can be used to identify and classify risk within communities. Here ...

BACKGROUND Despite the rapid adoption of genetically modified (GM) crops by farmers in many countries, controversies about this technology continue. Uncertainty about GM crop impacts is one reason for widespread public suspicion. OBJECTIVE We carry out a meta-analysis of the agronomic and economic impacts of GM crops to consolidate the evidence. DATA SOURCES Original studies for inclusion w...
