Subsidiary activity to farming practice
Beekeeping does not replace the agricultural activity already being practised, it simply enhances it by being a secondary activity to the main form of agriculture.
Bees do not require much land to be effective as an agricultural unit. The economic flight distance of a bee is approximately a 5km radius around a hive, which means bees often travel on to a neighbouring property to harvest nectar, pollen or find water. This means that a farmers does not require large expanses of land in order to keep bees, all they require is nectar baring vegetation within a 5km radius of the bee hives.
Creating value from inaccessible land
Human nature is such that in order for something to be protected it needs to have a value. Communities living on the borders of inaccessible land (nature reserves, security controlled areas etc.) often leads to conflict and poaching because people do not directly benefit from the area they are excluded from. Beekeeping can achieve a degree of relief to this tension by placing hives on the outside of the reserve (or within the reserved and monitored accompanied by rangers) and the bees will fly into a reserve and collect nectar for honey production. This gives the reserve a direct value to people living within their border zones and thus stops the need of crossing into reserves in order to get something of value to their lives. This is also applicable to barriers of geography such as rivers, mountains or valleys whereby bees fly into difficult to access zones allowing beekeepers to have benefit from them.
