The multiple contributions of livestock in natural resource based livelihood strategies are very wellrncommon in mixed farming system of the country. However,. with increasing in number of population, thatrnfollowed with serious land fragmentatioll and resource depletion, have caused the positive livestockenvironmentrninteraction to be deteriorated alld so that/he livelihood of the communities being adverselyrnaffected. This paper examines some environmental elements that are highly related with livestock sectorrnand assess their degree of interaction in mixed farming area of Sekachekorsa wereda, Jimma zone ofrnOromia Regional State .. The household's livestock productioll system assessed in relation to somernellvironmental resources specifically, grazing lalld, forest land, and crop land. The role of livestock illrnintegrated land resource management, and some socia-economic cOllstraints, that affect livestockrnproduction system and its contribution ill natural resource management are also assessed.The data for the study was collected from both primary and secondmy sources. For primmy data,rnhousehold survey was made by using structured questionnaires. For this end, a sample size of 120 hhsrnwere proportionally selected from these foul' kebeies. Key informant interview, FGDs, and observationrnwere also used for primmy data collectioll.

As result Ihernlivestock size at community level increases, while the pasture land decrease or remain unchanged. Thisrncauses serious animal feed shortage, and forced most households, mainly those with small land size, tornfeed on forestland, crop land and other marginal lands as alternative sources. These, coupled wilh otherrnvariables, like grazing system, drought, as well as poor institutional collaboratioll and policy measures,rnresulted in over all resources degradalion alld reduce the positive role of liveSlock in reso urcesrnmanagement and agricultural produclioll ill Ihe area, wilh vmyillg ill degree of serious across rariousrnagro-ecologies in which each sludied kebele fall.Helice, it is recommended Ihat, for a lives lock to play a more positive role in promoting agriculluralrnproductivity and ecological sustainabilily in the area and to conlrol its negalive impacts, severalrnilltervention are needed.
