본고에서는 GIS를 이용한 용도지역의 개선방안이 제시되었다. 대상지역으로는 경기도의 용인시를 대상으로 용도지역 중에서 준농림지를 대상으로 하였다. 관리자중심의 사용자의 요구분석사항을 거쳐서, 데이터베이스의 설계방안과 사용자 인터페이스를 구축하는 과정을 소개하였고, 다소 시범적이어서 기능상의 한계 및 완벽한 사용자 인터페이스의 미비 등에도 불구하고 일선의 지방정부 수준의 업무에서 사용되어질 수 있는 가능성을 제시하였다. 범용GIS인 ARC/INFO와 ArcView를 중심으로 구축되어졌고 퍼스널 컴퓨터에서 의사결정 보조시스템의 형식을 띠고 있는 본 시스템은 시간요소의 결합 등이 가미되면서 전반적 계획의 작성에 있어서 효율성과 효과성을 함께 제고할 수 있는 의사결정보조도구가 될 수 있을 것으로 기대된다.

We examined the nutritive value of common grass species in the semi-arid rangelands of Borana in southern Ethiopia using local experience based herbage preference (LEBHP) perception and laboratory techniques. Local pastoralists in the study area were asked to identify common grass species and rank them according to the species' preferences and palatability to cattle. The pastoralists listed a total of 15 common grass species which were then sampled during the main rain and cold dry seasons and analyzed for crude protein (CP), Neutral Detergent Fiber (NDF), Acid Detergent Fiber (ADF) and ash content to verify pastoralists' claim regarding the quality of individual species. The relative feed value (RFV) and dry matter digestibility (DMD) were also calculated using NDF and ADF contents. Spearman's rank correlation was used to examine possible relationships between laboratory results and pastoralists' experience on grass quality. Cenchrus ciliaris, Chrysopogon aucheri, Digitaria milanjiana, Eragrostis papposa and Panicum maximum were the top five species based on LEBHP perception. There were indications of inconsistency in terms of LEBHP perception among the different pastoral communities. The chemical composition of all grass species showed significant (p<0.05) variation between sites, seasons and species. The results showed that the CP values for the Borana rangelands were in the range of 8.7% in the main rain season to 5.1% for the cold dry season. The fiber constituents were relatively low in the main rain season compared to the cold dry season. Overall, Digitaria milanjiana had the highest CP (16.5%) content, while the least was recorded with Heteropogon contortus (10.8) and Aristida adoensis (9.8%) during the main rain season. It seems that the spatial variability of landscapes within the wider geographical regions, soil properties and texture, and land-use patterns probably contributed to site differences in species quality. Generally, the RFV of individual grass species was significantly (p<0.05) varied between and within sites. The ranking of species by pastoralists according to their preferences by cattle was highly correlated with the chemical composition of laboratory results of individual grass species with 'r' values for CP (0.94), ash (0.95), NDF (-0.98), ADF (-0.93) and ADL (-0.93). We suggest the complimentary use of LEBHP and laboratory techniques in evaluating the nutritive quality of rangeland forage species for sustainable animal production.

순환식 수경재배 시스템을 이용한 배액의 재활용은 수자원 및 생산비 절감, 환경오염 방지를 위하여 중요하다. 따라서 일반 토마토인 'Bonus'를 110일간 반촉성 수경재배하면서 생육 단계별 식물체, 공급액 및 배액의 무기원소 농도 분석을 통하여 순환식 수경재배 시스템 개발을 위한 기초 자료를 확보하고자 본 연구를 수행하였다. 착과절위에 따른 엽의 T-N 함량은 생육 초기에 약 4.1%로 높았으나 생육 후기로 갈수록 낮아져 8화방 개화기에는 3.9%로 낮아졌다. P 함량은 초기에 높았으며, 3-7화방까지는 비슷하였고, 8화방에서 낮았다. Ca, Mg 및 Na은 생육초기보다 후기로 갈수록 함량이 높아져 8화방 개화기에 가장 높았다. 토마토 생육 기간이 경과할수록 공급 양액과 배액의 $NO_3-N$, P, K, Ca 및 Mg 농도는 정식 5주 후까지의 생육 초기에는 비슷하였으나 생육 후기로 갈수록 공급액보다 배액에서 농도가 높아지는 경향이었다. B, Fe 및 Na의 경우 생육 초기에는 배액의 농도가 약간 높았으며 중기 이후부터 공급액보다 배액의 농도가 높았다. 이상의 결과는 토마토 순환식 반촉성 수경재배 시 배액의 무기원소 농도를 교정하기 위한 기초 자료로 활용될 수 있을 것이다.

이 논문은 중국의 반건조지대에 위치하는 네이멍구 동부의 커얼친 사지를 사례로 토지이용의 변화와 사막화의 전개에 대하여 검토하고 있다. 이 지역의 토지이용의 변화는 경지와 목축두수의 증가로 요약되며, 그에 따른 물과 식생의 이용 및 관리에 있어서의 문제점들이 사막화를 촉진시킨 것으로 나타났다. 사막화의 전개 유형은 이동사구 확대 유형, 하안 유사 확대 유형, 촌락 주변 반점상 유사 확대 유형, 초지와 경지 중의 반점상 유사 확대 유형으로 구분할 수 있었다. 토지이용 변화의 배경에는 1949년이래 사회주의 건설과 개혁개방으로 요약되는 사회적 변화가 자리 잡고 있다. 특히 대약진운동과 문화대혁명이라는 두 가지 정치적 운동과 개혁개방으로 인한 농민과 목축민들의 수익추구가 이 지역의 토지이용에 미친 영향이 컸다. 1990년대를 전후하여 사막화에 대한 각성과 더불어 여러 가지 사막화 예방 및 퇴치 정책들이 실시되고 있다. 그러나 이러한 정책들은 개방화 및 시장화라는 추세, 이 지역 농민들과 목축민들의 생존권과 수익, 그리고 무엇보다도 1949년 이후 이 지역에 고착된 교란된 인구구조와 그에 따른 토지이용체계에 의해 제약받고 있다.

Fodder supply condition was studied at 41 nomadic families in Gobi, Southern Semi-Desert area in Mongolia, from Dec. 1994 to Apr. 1995 to determine problems in cold, feed deficient season for establishment of sustainable livestock production system. The conditions of two family groups: those located in sparse vegetation (FG1), and those in comparably dense (FG2), were also compared. Commercial concentrate feed (concentrate), hay and Zoodoi were prepared for supplementation. Zoodoi was hand-made feed made mainly of Allium mongolicum and Allium polyrrhizum. Allium mongolicum tended to be used at FG1 frequently, and Allium polyrrhizum at FG2 depend on differences of micro vegetation. 44%, 90% and 39% of families prepared 165.6 kg of concentrate, 301.6 kg of hay and 6.8 kg of Zoodoi per sheep and goat (small livestock) on the average, respectively. The ratio of families that used concentrate at FG1 was smaller than those at FG2, though there were no significant differences on the amount. More hay was fed at FG1 than at FG2, and Zoodoi tended to be fed more in the FG1 group. Recipients were mostly restricted to young, female and sick small livestock that use the feeds effectively. More families gave concentrate and hay to the young than to the females and sick. They also gave more Zoodoi to young and sick animals than to females in this area. In the FG1 group, no differences were found between recipients on the concentrate supply. More families supplied hay to young animals than to sick ones, and Zoodoi was fed more to sick animals than to young and females. On the other hand, those in the FG2 found, more families fed fodders to young than to female and sick regardless of the kinds of feeds. The amount of fodder supplementation in the studied area was restricted, but accurate techniques of nomads to adapt the situation were clarified.

One of the major environmental issues Japanese cities is now facing with is the conservation of seminatural landscapes for the restoration of ecological integrity of urban areas. The satoyama landscape, which includes coppice woodlands, agricultural areas and rural settlements, is seen as an indispensable semi-natural landscape, formed as a result of man-nature interaction. However, because of the loss of the economic viability they are now abandoned and in the process of losing their ecological values. Today a number of local municipalities as well as NPO groups are involved in the conservation projects of these landscapes. Although satoyama landscapes are commonly believed to have maintained their character over the years, historical studies have revealed that these landscapes have experienced constant and dynamic changes due to a variation in human impacts. It is therefore understood that the conservation projects on satoyama landscapes should not intend to restore their past condition, but should wet the goal of maintaining their dynamic character by promoting ecological roles which the landscapes may play in the contemporary world. EXPO2005 project in Aichi Prefecture is a good example of a development project underway on satoyama landscapes which intend to conserve the landscapes by stimulating contemporary ecological for them. In EXPO2005 project the key issue was the conservation of semi-natural landscapes formed by constant and intensive human impacts over the centuries and thus allowing endemic and endangered species to be accommodated. The planning team proposed a scheme to restore economic viability of satoyama landscapes. The scheme involves re-introducing intensive human impacts through a new management system with an innovative technology. This may restore the economic viability of lumbers provided form satoyama woodlands. EXPO2005 is understood as a model case which stimulates contemporary ecological functions of satoyama landscapes by applying innovative planning concepts.

An exploratory study was conducted in Gopalganj, a southern district of Bangladesh to explore the role of wild date palm (Phoenix sylvestris Roxb.) husbandry in the rural economy. A total of 36 households in the study area were interviewed using a semi-structured questionnaire. A multistage sampling method with 10% intensity and a semi-structured questionnaire were used for the study. Based on the land holding capacity of the households, the farmers were categorized into five groups as landless, marginal, small, medium, and large. The date palm was distributed over seven different habitats of which roadside support the highest value (31%) followed by agricultural field and orchard (25% each). Though the large category farmers own most of the palms (43%), a considerable portion (562 individuals out of 1980) of it is managed by the landless farmers, who earn a substantial livelihood from the palms. The farmers manage the palm mainly for juice production; juice is either used fresh as drink or after some sort of processing as molasses and/or alcoholic beverage. Date palm husbandry contributes 32,601 Tk., 21,107 Tk., 20,626 Tk., 29,574 Tk. and 35,335 Tk. respectively to the five group seasonally and 50,980 Tk., 77,556 Tk., 90,208 Tk., 112,560 Tk., 140,675 Tk. respectively annually (1 US$ = 70 Tk.). Date palm trees contribute 65.48% of mean annual income to landless farmers followed by 27.21% to marginal farmers. However the poor marketing system result in decreasing the annual return from palm trees. Palm husbandry could be a promising source of rural incomes in Bangladesh if the farmers' traditional management knowledge was linked to more scientific management practices.

This paper provides two case studies of environmental impacts with socio-economic values. The first case is on flood protection levees conducted from 2003 to 2004 in Phu Tan district, An Giang province. The impacts were found by comparing full flood protection levees area (FFPL) to non-full flood protection levees area (NFFPL). Participatory Rural Appraisal (PRA) tools per each group of rich, middle, and poor people were used to list the impacts. Then, major impacts were selected by ranking and interviewing 60 households per site, and assessed by Cost Benefit Analysis (CBA) in rice production from 1996 to 2002 between two areas. The tested research indicated moving system of NFFPL to that of FFPL lost about 11 million VND/ha/year. The second case is on impacts of Penaeid shrimp farming conducted in Duyen Hai District, Tra Vinh Province in 2004-2005. Ninety households and 12 local officials were interviewed. Four PRAs were conducted and 36 water samples were taken inside and outside shrimp pond to measure values of DO, COD, Fe total, TSS, N-$NO_3{^-}$, N-$NH_4{^+}$, P-$PO{_4}^{3-}$, and Chlorophyll-a. Research results showed only 36.7% of the households got profit from shrimp farming. Highest financial efficiency was 0.72 for the semi-intensive system. Tested water indicators showed surface water quality did not match Vietnamese standard for surface water in coastal area (TCVN 5943-1995) and in rain. The water was very muddy and contaminated by organic aluminum. Summarily, the impacts were clarified more obviously via adding socio-economic values to assessment. Importantly, the values were transformed to household's income which is an indicator for policy-makers to consider the impacts obviously. Besides, data of different group of people impacted are cases contributing to consideration of the impacts in an appropriate social level.
