So even farmers like Dumont, who spent thousands to get her crop permitted by Mendocino County, are stuck with cash.
In East Africa, for example, clever agro-ecological research conducted over 15 years revealed that growing selected fodder, legume and grass species in combination with staple maize and sorghum crops permitted control of two serious pests that plague these crops.
I could expand on the way in which governments all over Europe have – while imposing a temporary ban for flowering crops – permitted the use of neonicotinoid insecticides for all other purposes, without any idea of what their impact might be on animals in the soil and the rivers into which they wash.
Much of Europe, while still forbidding the planting of GM crops, permits the importation of foods made from them.
To avoid competition, it may be necessary to root-or shoot-prune trees, use species with 'reverse phenology,' or adopt sequential planting of trees and crops to permit spatial complementarity in resource capture.
Traditionally, slash and burn shifting cultivation and complex cropping patterns permitted low yielding, but relatively stable, food production systems.
Dwarfing rootstocks have revolutionized the production of some tree and vine crops by permitting high-density plantings that increase fruit yield in the early years of orchard establishment.
Considering the results of plant growth and reproduction, relative competitive ability and population yield, it is likely that the Bt-transgenic and non-transgenic rice will coexist in agricultural ecosystems when commercial release of transgenic crops is permitted.
Its commanders promptly informed Ambassador Wood that they would only permit crop eradication if the State Department paid large cash stipends to the farmers for the value of their opium crop.
When fields are isolated (fragmented farmlands), farmers implement with some of their neighbours, collective rules of crop allocation that permit the management of common constraints, such as the lack of roads to access fields.
