The continuing deterioration of agricultural biodiversity has been raising tremendous concerns among conservation experts. This study examined the effect of farming activities on agro-biodiversity management in Cross River State. The study specifically addressed the types of farming activities carried out in the area; the effect of farming activities on agrobiodiversity; and, measures for enhancing the conservation of agrobiodiversity in the area. The population of the study comprised all rural farmers in the selected extension blocks in the state, while a randomly selected sample size of 180 was used for the study. Data were collected using a validated structured questionnaire and analyzed using descriptive statistics. The results of analysis revealed that bush clearing, bush burning, deforestation, continuous
cropping and herbicide use etc. were some of the practices carried out by the farmers in the area. It was also found that farming activities have effects such as soil erosion, loss of agrobiodiversity, water pollution, death of micro-organisms, leaching of nutrients and desertification among others. The study observed that the use of organic manuring, cover cropping, crop rotation, afforestation and terracing/contouring etc. can enhance the conservation of agrobiodiversity. It was recommended among other things that government should educate and train farmers on conservation farming techniques.
