t.e purpose of t.is st.dy was t. ident.fy t.e drivers of t.e shift.of t.adit.onal agro-ecosyst.ms and t.eir implicat.on on cat.hment.resources management.of East.rn Arc Cat.hment. of t.nzania. Lower Mnget. and Upper Zigi wat.r cat.hment. are sit.at.d wit.in East.rn Arc Mount.ins of t.nzania. Household quest.onnaire, key informant.int.rviews and focus group discussion were used for collect.ng primary dat.. t.e findings indicat.d t.at.most.of t.e part.cipant. (85.9% and 90.4% in Lower Mnget. and Upper Zigi cat.hment. respect.vely) depend on subsist.nce rain-fed agricult.re for t.eir livelihoods. However, t.ere are significant.changes in product.on as a result.of land fert.lit. det.riorat.ng and negat.ve climat.c changes (seasonal shift.. t.is has become a major challenge for most.of t.e farmers. t. cope wit. agro-ecosyst.m dynamics, farmers in t.e st.dy areas use bot. t.adit.onal and modern st.at.gies as illust.at.d in t.e result. sect.on. While t.adit.on always report.d t. be inexpensive, some modern agro-ecosyst.m pract.ces report.d t. cause silt.t.on, killing of fish and herbal plant., easy rot.ing of seeds (for maize) and bad aroma (for rice)in spit. of having a high rat. of ret.rn.

最近美国航空与空间计划署(NASA)开展的卡西尼—惠更斯外空探测计划发现,在直径为500km的卫星——土卫二上存在水冰和间隙泉的喷发活动。这一现象和在火星上工作的"机遇号"和"勇气号"漫游车所发现的液态水一起,证明了除地球以外的其他星球上过去和现在都存在水,其中的一些星体还有火山活动的证据,这意味着这些星球上可能存在过热液活动地质过程。讨论了火星、木卫二和土卫二可能存在的热液系统类型。这些热液系统类型是根据地球上的构造背景进行相似性研究后得出的,例如海底、火山和裂谷系统。将东非裂谷和贝加尔湖裂谷系统与火星t.arsis高原上巨大的水手大峡谷进行了对比,这些地区都是由地幔柱作用下构造—热液活动导致的地壳抬升、火山和裂谷作用。在火星上,地下冰或低温层会在火山活动和(或)小行星或彗星撞击作用下溶解而形成热液对流。
