text: prooleMs faced are of similar nature. we wilf briefly revie~ the data requirements of the two non-quantitative techniques before studying in three eltdlllples the needs of the quantitative procedores. U. NON-QUANTITATIVE p-LANNING PROCEOURtS Non-quantit3tive planning procedures involve subjective or qual­ itative pl.anning procedures and monitorin g ana evaluation systems. 1\n example of the former type of proceaures is the methoJ of the panel of experts: on the basis of their own experience of the economic proces~ ana taking into consiaeration the information given by a comprehensive set of econ01nic indicators. a group of experts give their opinions on the probable evolution of the economic situation ana suggest desirable changes. Monitoring and evaluation proceaures intervene at the latest sta\je of the planning process; however. t~ir data J"equif"ements are very close to those of the preparatory phases. The require d statistical inputs for these proceaures are well known and most of them are regu1arJy published by the statistical organizations. One can distinguish the basic agricultural statistics. the current agricultural statistics and the socio-economic indicators as fot1o,.,s: These statistics. generalty col,ected over long intervals, dre concerned with the more permanent features of agriculture. The items covered are those of a typical agricultural census: agricultural hold­ ings; land utilization; crop and livestocK produccion; far~ popu1ation and emplorment; production techniques. Tnis type of aata is especial­ ly useful to deter~ine the structure of the a~ricultural economy and to identify both the potent ii3t i tie'» and constraints in deve1 oping ttle product ion,. z - 3 - Current agricuftura1 stati~tics are related to the current activ­ ities on the farm and are collected at least on an annual basis. The information collected covers the physical characteristics of the cur­ rent production {area sown and harvested~ yield and production) and the economic aspects (prices received and prices pai<J by the fanners. 
analysis: The text appears to be discussing planning and decision-making processes related to agriculture, specifically the data requirements for non-quantitative planning procedures. The text mentions agricultural statistics, crop production, and farm population, which suggests a strong focus on agriculture. Additionally, the text mentions economic indicators and the evaluation of the agricultural economy, which implies a connection to economic development.
