B. Concept of joint Forest movement - Introduced by government in 1980
C. Ramesh Chandra Dagar - Worked on Integrated organic farming
D. Water ( Prevention and Control of pollution ) Act - 1986

Answer

To solve the question regarding which of the following is a mismatch, we will analyze each option provided in the question step by step.

### Step 1: Analyze the first option
- **Option**: Air Prevention and Control of Pollution Act 1981
- **Analysis**: This act was indeed established in the year 1981. Therefore, this is a correct match.

### Step 2: Analyze the second option
- **Option**: Concept of Joint Forest Movement introduced by the government in 1980
- **Analysis**: The Joint Forest Management (JFM) concept was introduced in the 1980s, specifically in 1988. Thus, this option is also a mismatch since it states 1980 instead of the correct year.

### Step 3: Analyze the third option
- **Option**: Ramesh Chandra Dagar worked on integrated organic farming
- **Analysis**: Ramesh Chandra Dagar is known for his work in integrated organic farming, which includes the use of organic fertilizers and GMOs. This is a correct match.

### Step 4: Analyze the fourth option
- **Option**: Water Prevention and Control of Pollution Act 1986
- **Analysis**: The Water (Prevention and Control of Pollution) Act was actually enacted in 1974, not 1986. Therefore, this is a mismatch.

### Conclusion
After analyzing all the options, we can conclude that the mismatches are:
1. The concept of Joint Forest Movement introduced in 1980 (correct year is 1988).
2. The Water Prevention and Control of Pollution Act stated as 1986 (correct year is 1974).

However, since the question asks for a specific mismatch, the Water Prevention and Control of Pollution Act being stated as 1986 is the most significant mismatch.

### Final Answer
The mismatch is: **Water Prevention and Control of Pollution Act 1986** (it was actually established in 1974).
