After sixty years of independence the dilemma of skewed land distribution still persists despite promulgation of three formal land reforms in Pakistan. Enormous evidences suggest that the rate of rural poverty is higher (Arif 2006) than urban areas and it is strongly correlated with the lack of assets in rural areas of Pakistan (Anwar et al 2004). Economic development theory illustrates that the rise in land holding distortions perturb crop productivity (Vollrath 2006). The study's pivotal objective was to assess the impacts of land distribution disparities on various farm indicators. Three study locations were identified on the basis of varying irrigation endowments within the Indus Basin rice"=wheat farming system i.e. a) irrigated perennial area (IPA) with year round irrigation b) irrigated non"=perennial area (INPA) with six months water availability and c) rainfed area (RFA) without public infrastructure. Land distribution was gauged by using quintile, Lorenz Curve and Gini Coefficient in each study location. However, total and partial factor productivities, cropping intensity, crop diversity etc were quantified by employing various statistical tools. Consequently, mixed results were observed but most of the results were found in favour of INPA. Land was found evenly distributed in INPA as compared to others while RFA area was found most unequal. Due to cheaper water availability, total and irrigation productivities were found overwhelmingly high in IPA area while labour productivity was explored as maximum in INPA as compared to other locations. Furthermore, cropping intensity, crop diversity, yield and gross margins per hectare of INPA outweighed the other locations. But RFA was found at bottom regarding the respective indicators. However, INPA was found better than all of the comparative study locations for most of the indicators. Based on the findings of the study and in the scenario of scarce water resources, it is strongly suggested that redistributive land reforms are necessary in land scarce and labour abundant developing countries like Pakistan. It is a key to enhance farm productivity, reduce poverty and food insecurity in the developing nations. }
