| 中央アジアに位置するトルクメニスタンは、国土の大部分が年間降水量200mm以下であり、農耕地は国土面積のわずか3.3%にしか満たない。農耕地の98.6%は灌漑によっており、カラクム運河の水資源がトルクメニスタンにおける農業活動の生命線となっている。1996年から1998年にかけて、牧草類生産用の農耕地を穀物類栽培に大きく割り当てたこと、そして、穀物類と綿花の収量が向上したことにより、大規模農場による穀物類と綿花の栽培が増加した。一方、独立した個人農民への土地私有権の分配はいまだほとんど進展していない。しかし、トルクメニスタンにおける農作物生産量、農作物収量、家畜飼養頭羽数および畜産物生産量は増加傾向にあり、徐々にではあるが民営化の効果は現れ始めている。土地利用権としての農業用地の農民への還元、農民への優遇政策、基本資材の無料供給、国土面積の狭さからくる流通における利点などが、農民の生産活動に有利に働いた。農耕地拡大と農作物収量の向上とともに、トルクメニスタンにおける農作物生産はこれからも成長を続けるであろう。 The annual rainfall in most parts of Turkmenistan is less than 200 mm，and consequently，cultivated fields comprise only 3.3% of the total land area. The majority of the cultivation，98.6%，makes use of irrigation，and the water supply from the Karakum Canal serves as a vital resource for the cultivation... |

| The report examines the relationships between agricultural policies in the North China Plain, the approaches to water management that evolved from them, the quantity of water that was actually used, and the consequent groundwater depletion beneath Luancheng County, Hebei Province, from 1949 to 2000. To systematically address these relationships, we use a comprehensive water-balance approach. Our results indicate that a single, longstanding policy-that of using groundwater to meet the crop-water requirements not supplied by precipitation-is responsible for the steady rate of groundwater decline. |

| In order to evaluate food security, technology potential and the environmental impacts of production in a strategic and regional context, it is critical to have reliable information on the spatial distribution and coincidence of people, agricultural production, and environmental services. This paper proposes a spatial allocation model for generating highly disaggregated, crop-specific production data by a triangulation of any and all relevant background and partial information. This includes national or sub-national crop production statistics, satellite data on land cover, maps of irrigated areas, biophysical crop suitability assessments, population density, secondary data on irrigation and rainfed production systems, cropping intensity, and crop prices.... |

| Given its vast land resources and favorable water supply, the Democratic Republic of Congo's (DRC) natural agricultural potential is immense. However, the economic potential of the sector is handicapped by one of the most dilapidated transport systems in the developing world (World Bank, 2006). Road investments are therefore a high priority in the government's investment plans, and those of its major donors. Whilst these are encouraging signs, very little is known about how the existing road network constrains agricultural and rural development, and how these new road investments would address these constraints. To inform this issue the present paper primarily employs GIS-based data to assess the impact of market access on agricultural and rural... |

| Nearly all farm business ventures involve financial risk. In some instances, private and public tools used to manage financial risks in agriculture may influence farmers' production decisions. These decisions, in turn, can influence environmental quality. This bulletin summarizes research and provides some perspective on private and public attempts to cope with financial risks and their unintended environmental consequences. Specifically, it examines the conceptual underpinnings of risk-related research, challenges involved with measuring the consequences of risk for agricultural production decisions, government programs that influence the risk and return of farm businesses, and how production decisions influence both the environment and the risk and... |

| Objetiva-se conhecer as facilidades e/ou dificuldades enfrentadas pelos produtores, os entraves à organização social, as dificuldades para praticar atividades irrigadas, as principais razões para a não exploração de mais terras e tendências futuras apontadas pelos produtores situados nos perímetros e assentamentos do entorno da barragem do Açude Castanhão, no vale do Jaguaribe, no Estado do Ceará. Os dados são provenientes de pesquisa direta, coletados por meio de aplicação de questionários. Utilizam-se o método descritivo para análise e discussão dos resultados, após cálculos de freqüências, tabelas e outras informações estatísticas selecionadas. Os principais problemas apontados pelos produtores dos perímetros são a falta de capital de giro, seguido pela... |

| In 2003 a research study looked at the position of smallholders; the survey was carried out using questionnaires and interviews. The 613 farms included in the survey were situated in 3 counties in the Southern Great Plain of Hungary and in 3 counties of the Western part of the country (Transdanubia). The results of the survey showed that there was a firm tendency of concentration among the Hungarian individual farms. Though their average size is about 3 ha, the number and area of farms over 50 ha size are rapidly growing and taking a significant part of the total individual agricultural area. The number of small farms is great but their total farming area is relatively small. The concentration takes place primarily due to renting. The land market is... |
