This paper examines how fishing communities in the Tonic Sap Lake make their living in the context of declined resources, increased competition between fishers, the resources politics and the increased trades around the Lake. The paper concludes that in the old day, communities around the lake were related to one another through bartering rice and fish. However, at present, as resources declining, these communities compete over resources, and in doing so, they build relationship and connection with powerful elites including officials, fish traders and the fishing operators, who could protect them in fishing. As a consequence, fishers are trapped in the webs of vicious cycle of poverty, conflicts, corruption and patronage system and exploited and sucked in these webs.展开更多

Outside discussions on the land issue, one of the agreements made at the Lancaster was that 12 Assembly Points be set up throughout the country to house guerrillas and initiate a demobilising exercise. Each was to be manned by a small contingent of the British Army and all the Zimbabwean National Liberation Army （ZANLA） and Zimbabwe People＇s Revolution Army （ZIPRA） guerrillas, in any one area, were to go to the closest assembly point. The Assembly Points, which included Dzapasi/Foxtrot in Buhera, Chitungwiza, Connemara, and Mike in Lupane, at one time housed 17,000 guerrillas. Tension was very high inside and outside these Assembly Points. In 1980, there were sporadic outbursts of violence around these points all over the country. The fights recurred in 1983 killing over 300 people. This research proposes to pore over the nature of the violence in this historical epoch to try and understand its roots as well as to establish whether attempts at accountability, reconciliation, healing, and integration were made after the Assembly Points era and if not, whither Zimbabwe？展开更多

The Sendai Framework for Disaster Risk Reduction 2015–2030(SFDRR) leaves important implementation issues unspecified and potentially creates both problems and opportunities for complex,multilevel governance systems in coping with hazards and disastrous events. Early warning systems(EWS), if built into the mainstream of planning for development and disaster relief and recovery, could present a significant opportunity to realize many SFDRR goals. We explore the complexities of using hydrometeorological EWS to prepare for drought and flood disasters in the densely populated communities of Pakistan’s Indus River Basin in contrast to the African Sahel’s less densely settled grasslands. Multilevel governance systems are often dominated by a topdown, technocentric, centralized management bias and have great difficulty responding to the needs of peripheral and vulnerable populations. People-centered, bottom-up approaches that incorporate disaggregated communities with local knowledge into a balanced, multilevel disaster risk management and governance structure have adramatically better chance of realizing the SFDRR goals for disaster risk reduction.展开更多

The bias-corrected climatic variables were generated for the Fifth Assessment Report of the Intergovernmental Panel on Climate Change(IPCC AR5) by the Inter-Sectoral Impact Model Intercomparison Project(ISIMIP). Results showed much larger fractional changes of annual mean Evapotranspiration(ET) per unit warming than the corresponding fractional changes of Precipitation(P) per unit warming across the country, especially for South China, which led to a notable decrease of surface water variability(P-E). Specifically, negative trends for annual mean runoff up to -0.33%/ year and soil moisture trends varying between -0.02% to -0.13%/year were found for most river basins across China. Coincidentally, interannual variability for both runoff and soil moisture exhibited significant positive trends for almost all river basins across China, implying an increase in extremes relative to the mean conditions. Noticeably, the largest positive trends for runoff variability and soil moisture variability, which were up to 0.41%/year and 0.90%/year, both occurred in Southwest China. In addition to the regional contrast, intra-seasonal variation was also large for the runoff mean and runoff variability changes, but small for the soil moisture mean and variability changes. Our results suggest that future climate change could further exacerbate existing water-related risks(e.g., floods and droughts) across China as indicated by the marked decrease of surface water amounts combined with a steady increase of interannual variability throughout the 21 st century. This study highlights the regional contrast and intra-seasonal variations for the projected hydrologic changes and could provide a multi-scale guidance for assessing effective adaptation strategies for China on a river basin, regional, or as a whole.展开更多

More specifically, official China has stated the goal of achieving a ＂moderate＂ or ＂appropriate＂ universal welfare state in order to mitigate increasing inequality and the individualization of social risk. Consequently, the new millennium witnessed a wave of social reforms in China's Mainland, the most significant of which were arguably within the policy fields of health insurance, pensions and unemployment protection. This paper reviews reform efforts within these three policy fields and discusses progress and looming challenges with the concept of universalism as the yardstick. From the perspective of universalism, the social right dimensions of coverage （the share of the population included）, generosity （benefit levels or adequacy of welfare proved for those included） and financing （such as state, contributions or private） are quintessential. Coverage of social protection has increased significantly with new schemes in all three policy fields. The hukou divide in coverage of social insurance is not as pronounced as before, especially in health insurance. However, major challenges still persist. Declining benefit generosity or adequacy has been a tendency in both pensions and unemployment protection. The pension system also faces problems of financial fragmentation and unsustainability. The health insurance system is still inadequate in terms of protection against health risks, particularly serious or chronic illnesses. These issues are more pronounced in schemes catering to rural residents or urban residents outside the labor market. This reflects that schemes for urban workers are still much more generous. In this regard, recent tentative efforts to integrate the divided welfare system should be noted.展开更多
