Show Hint
The D&D process operates like medical diagnostics:
- First, learn about the patient (Pre-diagnostic/Pro-diagnostic) \(\rightarrow\) Diagnose the disease (Diagnostic) \(\rightarrow\) Design the treatment (Design) \(\rightarrow\) Execute the prescription (Implementation).

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
The Diagnostic and Design (D&D) methodology was developed by the World Agroforestry Centre (ICRAF) to diagnose land-use problems and design appropriate agroforestry systems to address them.
Step 2: Detailed Explanation:
The D&D methodology is a structured, iterative procedure consisting of the following chronological phases:
1. A. Pre-diagnostic Pro-diagnostic: Definition of the land-use system, site selection, and initial collection of background information.
2. B. Diagnostic: On-site field diagnostic surveys to identify constraints, problems, and bottlenecks in the system.
3. C. Design and evaluation: Identification of potential agroforestry interventions and design of candidate systems to resolve the diagnosed problems.
4. D. Planning and Implementation: Planning the research and development program, followed by on-farm trials and implementation.
Thus, the correct sequence of steps is ABCD.
Step 3: Final Answer:
The correct order of steps in the D&D methodology is ABCD.

- Read the following statements and choose the correct answer about silvicultural system/s adopted for the management of Shorea robusta:
Statement (I): Under clear felling system, a rotation age is fixed and the entire area clear felled and the crop is of uniform age.
Statement (II): Selection system is adopted for areas which are badly eroded and where regeneration is problem and regeneration is obtained by natural means, which may be supplemented by planting.
Statement (III): In coppice with standards system, a few standards are retained and the other trees above the exploitable diameter are clear felled and regeneration is obtained by means of coppice.
