Environmental Evaluation and Monitoring of Agro-Ecosystems Biodiversity

An Agro-ecological Simulation Model System

• Abstract. In this paper five different models, as five modules of a complex agro-ecosystem are investigated. The water and nutrient flow in soil is simulated by the nutrient-in-soil model while the biomass change according to the seasonal weather aspects, the nutrient content of soil and the biotic interactions amongst the other terms of the food web are simulated by the food web population d...

Complex agro-ecosystems for food security in a changing climate

Attempts to increase food crop yields by intensifying agricultural systems using high inputs of nonrenewable resources and chemicals frequently lead to de-gradation of natural resources, whereas most technological innovations are not accessible for smallholders that represent the majority of farmers world wide. Alternatively, cocultures consisting of assemblages of plant and animal species can ...

AGRO-ECOLOGICAL ZONES, THEIR SOIL RESOURCE AND CROPPING SYSTEMS Agro-Ecological Zones, their Soil Resource and Cropping Systems

India is gifted with heterogeneous landforms and variety of climatic conditions such as the lofty mountains, the raverine deltas, high altitude forests, peninsular plateaus, variety of geological formations endowed with temperature varying from arctic cold to equatorial hot, and rainfall from extreme aridity with a few cms (<10 cm) to perhumid with world’s maximum rainfall (1120 cm) of several ...
