Most of these projects have caused major changes in land use, leading to dispossession and displacement of a large number of people and their involuntary resettlement in other areas. Development induced displacement brings loss of productive assets, dismantling of social networks, destruction of ancestral property, and even increased morbidity and mortality rates in some instances. Therefore, this paper seeks to explore further the micro-level impact of agricultural land acquisition on livelihood pattern of both genders to the establishment of the industry on the fertile agricultural land in the k＇haragpur subdivision of Paschim Medinipur district in the early 1990s with the cooperation of West Bengal Government, India. Land acquisition without any policy of rehabilitation caused not only landlessness but also created joblessness among the affected population and at the family level, it has resulted food insecurity and increased workload among the women. The women on the other hand made desperate attempts to cope up the burden by working within and outside the domestic domain.展开更多

Similarly, China has been undergoing a huge movement of domestic migration, more than 200 million farmers moving into cities and towns from the countryside, under the impact of modernization and globalization; this creates a great challenge to its traditional citizenship. The paper includes five parts and will： 1 ） give an overview of the whole process of this huge migration since the Reform and Opening Up at the end of the 1970s ; 2 ） analyze the internal and international dynamics of migration and particularly its great challenges to citizens＇ civil rights, obhgation, and identity; 3 ） illustrate Chinese policies dealing with the new large migration; 4, ） assess the essential changes in citizenship from this migration; and 5 ） find its meaning and consequence in terms of political philosophy.展开更多
