THE hillside next to the homes of thousands of tenants on a Lam Tin estate has been dug up and turned into dangerous farmland. Natural shrubs and grass have been removed, wire fences put up, and vegetables, flowers, and even banana trees are growing - some around notice boards warning against excavation of Crown land. More than 3,000 families live in blocks on the Kwong Tin Estate by the hill. They fear loosening of the soil could lead to a landslide. The saga has gone on for years because land officials are arguing among themselves as to who should be responsible. The slopes are on Black Hill, which divides Kwun Tong and Sai Kung districts, but the exact demarcation is not clear. The place has been popular with morning joggers and walkers. Some elderly walkers like to grow vegetables there to 'beautify' the area, according to residents. Kwun Tong District Board member Francis Tang Chi-ho said he complained to the Home Affairs and Lands departments more than a year ago but nothing was done. 'The departments have confirmed it is illegal farming but the Geotechnical Office says the slopes pose no immediate danger so they decide to turn a blind eye. 'The officials must be waiting until some people are killed by landslides.' He suggested the Government order a joint Kwun Tong and Sai Kung operation. Democratic Party legislator Fred Li Wah-ming, a Kwun Tong District Board member, has promised to raise the issue with the Government.
