I had submitted an application under the Agricultural Land Scheme but despite the lapse of time I havent received any feedback on my application. Can Lands Authority lease the land in question to third parties even though I had applied for it?

In view of the very large number of applications that were received under the scheme, the laborious and technical nature of the work and also the limited human resources, the processing of applications made under the Agricultural Land Scheme is not progressing as fast as Lands Authority would like it to.  Nevertheless this should not cause you any concern since the land you applied for will not be granted to third parties before your application is considered.
