SUMMARYThe objective of this study was to investigate the user communities' understanding and interpretation of changes in rangeland use and productivity in the communal lands of Zimbabwe. While external knowledge has been instrumental in defining the drivers and effects of ecological changes hitherto, the role of local knowledge is becoming increasingly important in explaining factors that inform user community perceptions and guide their decisions on the use of rangeland resources. Data on community perceptions were collected in four villages, using Participatory Rural Appraisals in each village and household surveys with a total of 104 households. This study showed that user communities in Nkayi district differentiate rangelands among seven categories of livestock feed resources and how these have changed over time. Communities viewed rangelands not as one continuous, designated and specialized land parcel, but differentiated the land by location, productivity, management and uses in different times of the year. Although land use changes affecting these livestock feed resources were considered to be widespread and multi-directional (both negative and positive) they did not cause widespread degradation. Rangelands converted to croplands were not completely lost, but became important dual purpose land parcels fulfilling both household food security needs and dry season livestock feed requirements. The importance of croplands as a feed resource is reflected in the emergence of new institutions governing their use for livestock grazing and to guarantee security of tenure. On the other hand institutions governing the use of common property rangelands decreased or weakened in their application. The study concludes that while this situation presents ecological challenges for the rangelands, it offers opportunities to find innovative ways of utilizing croplands as the new frontier in the provision of dry season feed resources to smallholder farmers in highly variable environments. Implications for livestock water productivity need to be investigated and water saving technologies should be promoted in the land use intensification processes.

<em>Abstract.</em>—Beaver dams alter the hydrology and geomorphology of stream systems and affect habitat for fishes. Beaver dams measurably affect the rates of groundwater recharge and stream discharge, retain enough sediment to cause measurable changes in valley floor morphology, and generally enhance stream habitat quality for many fishes. Historically, beaver dams were numerous in small streams throughout most of the Northern Hemisphere. The cumulative loss of millions of beaver dams has dramatically affected the hydrology and sediment dynamics of stream systems. Assessing the cumulative hydrologic and geomorphic effects of depleting these millions of wood structures from small and medium-sized streams is urgently needed. This is particularly important in semiarid climates, where the widespread removal of beaver dams may have exacerbated effects of other land use changes, such as livestock grazing, to accelerate incision and the subsequent lowering of groundwater levels and drying of streams.

The ecological consequences of contemporary land-use in the neotropics have important influences on national park management in the region. Historical patterns suggest that major land-use changes have occurred regularly, and that these patterns have recently intensified. Is there a relationship between specific land-uses and specific threats to protected areas? Can this relationship be detected in a population of parks?In a survey of managers of 183 national parks, 122 returned questionnaires from 19 countries in the neotropics. We found that a range of land-uses, from livestock grazing to quarrying, are occurring in and around the parks. The results of our statistical analysis indicate that many of these activities are associated with specific threats to park resources: for example, poaching for subsistence was statistically associated with each of the ten most-reported threats.We offer two suggestions for improving our understanding of environmental degradation within parks. First, that research and park management be expanded to acquire a regional focus, namely that the land-transforming activities which threaten park resources can best be understood by incorporating the regional-social and political-economic contexts in the analysis. Second, that the influences of the global economic system be increasingly considered in conceptual frameworks of conservation biology.

Human use of land has altered the structure and functioning of ecosystem. The most spatially and economically important human uses of land globally include cultivation in various forms; livestock grazing, settlement and construction, reserves and protected lands and timber extraction. The patterns of land use give us insight into the factors that have caused the land cover to change. A better understanding of the determining factors of land use changes is of crucial importance to the study of global environmental change. This paper theoretically strive to evaluate the contributions of government policies and programmes in transforming the various land uses in the urban centers of Ogun state with a view to provide better understanding among the stakeholders in real estate investment. The paper recommended that although landuse changes is an inevitable consequences in the developing nations, there is the need to consider the positive and negative aspect of the policies in order not to jeopardize the available environmental resources for sustainable development. The paper concluded by emphasized the need for government to carry the citizen along in the various policies and programs for even development.

In the current study area, livestock are an integral part of the mixed farming system, and play very important roles as sources of draught power, nutrition, cash income, employment and poverty alleviation. However, feed shortage, especially during the dry season, is the most important constraint to optimal productivity. This study aimed to investigate livestock feed resources and feeding practices, coping strategies with seasonal scarcity, and to identify major constraints to livestock production in a mixed farming system around the Gilgel Gibe catchment, southwest Ethiopia. Data were collected from 342 households using a structured questionnaire. The results showed natural pasture, crop residues, stubble grazing, and roadside grasses were the main feed resources, in that order. None of the respondents practiced improved forage cultivation due to insufficient land and lack of knowledge on forage production and utilization. Free grazing was the most predominant feeding system. Almost all respondents experienced dry season feed scarcity. Conserving crop residues and hay, purchasing roughages, reducing herd size and renting grazing land were the major coping strategies to feed scarcity. The farmers’ perceived major constraints to livestock production were feed shortage, animal diseases, and low productivity of local breeds. Institutional, technical and technological interventions are suggested to alleviate the constraints to livestock production in mixed crop-livestock systems in the study area and outside with similar settings.

Dry And Rainy Seasons

The increasing of malaria cases in recent years at Kecamatan Kalibawang has been suspected correspond with the conversion of farming land-use which initiated in 1993. Four years after the natural vegetation in this area were changed become cocoa and coffee commercial farming estates, the number of malaria cases in 1997 rose more than six times, and in 2000 it reached 6085. This study were aimed to observe whether there were any differences in density and diversity of Anopheles as malaria vector between the cocoa and mix farming during dry and rainy seasons. The results of the study are useful for considering the appropriate methods, times and places for mosquito vector controlling. The study activities comprised of collecting Anopheles as well as identifying the species to determine the density and diversity of the malaria vector. Both activities were held four weeks in dry season and four weeks in rainy season. The mea-surement of physical factors such as temperature, humidity and rainfall were also conducted to support the study results. Four dusuns which meet the criteria and had the highest malaria cases were selected as study location. Descriptively, the results shows that the number of collected Anopheles in cocoa farming were higher compared with those in mix horticultural farming; and the number of Anopheles species identifi ed in cocoa farming were also more varied than those in the mix horticultural farming.Key words: bionomik vektor malaria, anopheles,
