“…Outmigration of men into urban centers leaves women and old people in rural areas. Women may face difficulties in accessing agricultural inputs, and usually the most able-bodied workers leave the rural 29 Muchena et al (2005) cited a number of researchers who have not found population growth to contribute to widespread soil degradation and fertility decline, such as studies by Mazzucato and Niemeijer (2001) in Burkina Faso; by Tiffen, Mortimore, and Gichuki (1994) in Kenya; and by Walker and Ryan (1990) in the semiarid areas of India. According to these studies, villages have been managing natural resources without giving rise to irreversible degradation, despite population pressure.…”

A field experiment was conducted between August and October, 2014 at the Department of Microbiology to assess the effect of organic and inorganic fertilizers on the population and activities of Phosphate Solubilizing Bacteria (PSB) in the rhizosphere of maize variety BR9928DMRSR-Y. Three treatment groups were used in the study and these were: Groups which received applications of organic fertilizer (Poultry litter) alone, groups which received applications of inorganic fertilizer (NPK) and the third group which was the control (CON) did not receive any fertilizer application. A total of twenty-three bacteria were isolated and in-vitro screening was done for different phosphate solubilization activity. The study revealed that maximum population of total heterotrophic bacteria (26.8×10 9 CFU/g) was obtained with organic fertilizer (OM) tre atment. Among the different PSB isolates, OMPSB had the highest bacterial count of 10.2×10 9 . The lowest bacterial populations were obtained from IFPSB with 6.0×10 9 CFU/g. Out of the 23 PSB isolates, 18 were positive for phosphate solubilization with OMPSB8 showing the highest zone with 16 mm. Results showed that application of organic fertilizers enhanced the bacterial population and also showed increase in phosphate solubilization activities in rhizosphere soil compared to NPK and control treatments. This shows that organic fertilizers would be able to sustain the soil fertility for a longer period by meeting the demand of present and future generations.

“…For example, in order to encourage farmers to participate in environmental protection efforts, helping local farmers expand their sources of livelihood, diversify their incomes, and mitigate people′s uncertainty and vulnerability to natural disasters are needful for reducing land pressures. It is necessary to improve their resource availability, local environmental management capacity, and environmentally friendly technologies Muchena et al, 2005). Education level is often correlated with poverty, as the poor often lack sufficient funds to invest in education.…”

“…As there is no one-size-fits-all policy, it is important to understand which factors affect the specific land use or people's environmental activities in order to be clear about the properties of specific regional resources, development and investment opportunities, and technical applications. The mechanisms and factors influencing the relationship between poverty and environmental degradation would be obvious so that the government can fully leverage such factors to provide effective guidance (Muchena et al, 2005;Vignola et al, 2010).…”

Poverty reduction and environmental protection are two global tasks for sustainable development. The study perspective has changed over time, from narrowly focusing on poverty reduction to comprehensively strengthening human-welfare. We reviewed key references targeting the theoretical content and practical approach relying on poverty, environment protection and ecosystem services. We discussed the contradicting views on the relationship of poverty and environmental degradation, and then illustrated the study progress of a cutting-age topic-ecosystem services which pave a way to address poverty reduction and environmental protection together. At last, we investigated essential factors that affect the development and environmental protection. Considering the evolution of the concept of poverty, we found that the environment has occupied an increasing proportion in the cognizance of poverty. The relationship between poverty and environmental degradation is regional uniqueness. In practical aspect, projects based on the management and valuation assessment of ecosystem services draw researchers′ attention all over the world. The appropriate scale, essential economic incentives, morality, law and social equality are key factors affecting individuals′ decisions which directly relate to the sustainable development.
