Can Forest-protection carbon projects improve rural livelihoods? Analysis of the Noel Kempff Mercado climate action project,Bolivia

We studied the Noel KempffMercado Climate Action Project (NKMCAP),Bolivia, to assess whether forestprotection carbon (C) projects cansignificantly benefit local people. Wehypothesized that forest protection canonly securely deliver C if significantstakeholders are meaningfully andtransparently involved, traditional orcustomary rights are recognized and theirloss compensated for, and there are directlinkages between conservation anddevelopment objective. Our researchfocused on 53 members of the communities ofFlorida, Porvenir and Piso Firme and 36secondary stakeholders. In each of thevillages we held half-day meetings withcommunity leaders, complemented bysemi-structured one-hour interviews with 5,10, and 7 families, representing 20%, 10%and 8% of each community. The long-termimpact of the NKMCAP on the localcommunities may well be positive. However,in the short run, certain sections of thelocal communities are financially poorer. Forest protection projects clearly have thepotential to sequester C, protectbiodiversity and simultaneously contributeto sustainable rural development, but ifthey really are to improve rurallivelihoods, they must be designed andimplemented carefully and participatively.     

Seed yeast cultivation for salad oil manufacturing wastewater treatment

The mixture of five yeast strains obtained from soil could remove about 85% TOC of oil-rich wastewater in batch test.While the highest MLSS was obtained at an N:C of 1:5,the oil removal decreased with the increase of N:C during yeast sludge cultivation.Ammonium chloride was the best nitrogen source for yeast cultivation from the viewpoint of yeast growth and oil utilizxation.An ammonia concentration of over 1300 mg/L led to mass death of yeast at a pH of 5.The ammonia concentration should be controlled at a level of 1000 mg/L or lower.     

呼和浩特市发电厂污染物综合治理与资源化利用技术研究

本文以呼市发电厂废水、粉尘和灰场污染治理为例，研究制定发电厂粉煤灰综合治理与回收利用技术方案、旧灰场的生态工程建设和冲灰水的回收利用方案，通过污染物治理，废水的利用率达到85％，粉煤灰处理后的产草量和年利用率为98％，灰场的植被覆盖度达到97％，通过治理使发电厂的污染物排放量减少，废弃物资源得以利用，灰场变成环境优美的生态旅游区，为我国电厂的治理工作提供一个切实可行的科学依据。     

入冬水生高等植物的衰亡对河流水质的影响

上海市郊河流水体中有很高的氮、磷和有机负菏，由于受水生高等植物生灭的影响，初春河流中的氮、磷和有机负菏明显高于上一年的初冬，河流中的水生高等植物能大量地吸收水体中的氮、磷，抑制藻类生长，净化水质；但其植株残体在水中的腐解，又会重新释出营养元素，造成对水体的二次污染。在冬季，随着水生高等植物的大量死亡这种污染更加明显，应加强对水生高等植物的利用，尝试建立既能净化水质，又有创造经济效益的生态工程模式，使市郊受污水体得到资源化利用。

含纤维素废水生物水解的应用研究

提取植物或动物纤维所产生的高浓有机废水，含短小纤维、木质素、纤维素、半纤维素、蜡质、果胶及其分解产物(糖、脂肪酸、醇等)，较难生物处理，属含纤维素废水。试验研究和生产应用表明，生物水解对含纤维素废水中高分子有机物，可予分解并提高度水可生化性：在常温、PH约9．5时，水解池污泥浓度达6．5～16．0g/L，容积负荷达2．9kgCOD／m^3．d，COD去除率为24—36％，VFA提高3．9—5．1倍，BOD／COD提高12～16％。分析认为：中温、酸性，纤维素、木素含量低时，水解效果应更好。     

扬子地块西南缘低温成矿域Au、Sb、Hg、As矿床区域分布上的共生分异及控制因素

扬子地块西南缘大面积低温成矿域的Au、Sb、Hg、As矿床,常出现共生分异的现象,在空间上形成Au、Sb、Hg、As矿床、矿带相伴出现而又相对独立的规律性分布。在详细研究Au、Sb、Hg、As矿床、矿带区域分布及其产出地质背景的基础上,从不同的角度,对制约Au、Sb、Hg、As矿床、矿带共生分异的因素进行了探讨。
