Language：English Publishing type：Research paper (scientific journal)
This paper describes potential factors for realising sustainable mariculture enterprises. It then proposes the potential key factors sought by stakeholders in
mariculture industries, including those involved in the input, production, and marketing stages, as well as experts (academics, researchers, and policymakers). To determine the key factors of sustainability, some gradual processes were conducted: (1) self-validation; (2)scientific validation; and (3) social validation. A total of 141 respondents (the stakeholders) were involved in this study. A principal component analysis was used to identify the critical key factors within the scales used. The Matrix of Crossed Impact Multiplications Applied to a Classification (MICMAC) was used to map the key factors and their relationships. This paper identifies and proposes key factors as references for policy formulation and decision-making to improve mariculture management. Further, influence, relationship, and dependence among
the key factors and societal implications of this study are discussed. -

Indonesian Permaculture:
PUTRO Radityo Haryo, MIYAURA Rie
Tropical Agriculture and Development 64 ( 3 ) 113 - 124 2020
Language：English Publisher：Japanese Society for Tropical Agriculture
<p>Permaculture-based farming systems are relatively unexplored in the humid tropics. A few studies have shown that permaculture in such areas has diverse roles and contributions, but these are poorly understood. We hypothesized that the unique social needs of local people or the natural environment in the humid tropics influence how permaculture systems are shaped to operate and have roles that fit under local context. The present study sought to identify and validate these influences toward three different aspects of the permaculture farm: 1) operations, 2) management, and 3) crop diversity. Field surveys were conducted in Indonesia between 2016–2019. A total of six permaculture farms were found across the country, and four farms (one in Yogyakarta and three in Bali) were able to cooperate for the present study. Analysis of quantitative data, such as for determining crop diversity, involved using the Shannon and Simpson diversity indices. We identified that the surveyed permaculture farms’ operations, farm management, and crop diversity were shaped by fundamental permaculture principles, socioeconomic factors such as operational needs and profit-related managerial decisions, and socio-cultural factors such as the beliefs of owners and local societal needs. All permaculture farms shared structural similarities with the Indonesian home garden, ‘<i>pekarangan</i>’ and it is preliminarily assumed that they were based on such design. A combination of these factors shaped Indonesian permaculture systems to operate in multiple ways, with unique farm management practices, and produce diverse types of crops.</p>

We evaluated the allelopathic potentials of 145 plant species collected from several locations in Malaysia using the sandwich method. Among them, the bark of Goniothalamus andersonii J. Sincl. proved most inhibitory to radicle growth of lettuce seedlings, followed by leaves of Ageratum conyzoides L. (Asteraceae), Amaranthus spinosus L. (Amaranthaceae) and Goniothalamus longistipites Mat Salleh (Annonaceae) bark. Goniothalamin was identified as the potent allelochemical from the bark of G. andersonii. The EC50 value of goniothalamin against the growth of lettuce radicles was 50 µmol L-1.

ペルー中央部マンタロー盆地のプカラ村にて2002年9月に実施した実態調査に基づいて,主要作物の試算分析を行った。アンデス農民の主食であるジャガイモ,トウモロコシおよびソラマメの栽培においては経済的持続性が確認できた。しかし,ジャガイモの生産リスクが著しく高いことが明らかになり,収量は低いが低コスト栽培のマシュアが家族の主食確保における保険機能を果たすと考えられた。

フィリピンの首都マニラへの有機野菜供給地として重要な位置をしめるカビテ・タガイタイ地域において、８農場を事例として栽培技術と経営について検討した。有機レタス栽培は、栽培周期が短いため労働投入量も低く抑えられるが、低収量であることが特徴である。しかし、有機産物による付加価値により、高級ホテルやレストランとの契約が可能で、低コスト高収益経営が実現できることが明らかとなった。

東南アジア地域における有機農業を支える担い手として企業経営もしくは家族経営のいずれが中心になるかという問題意識のもとで,研究蓄積がほとんどない農企業による有機農産物の生産・流通の実態と課題の解明を,フィリピンのマニラ近郊での事例分析に基づいて試みた。東南アジア地域では技術力・資金力・販売能力を備えた農企業による有機農産物の自社生産さらには周辺農家との契約生産が,有機農業の拡大と持続に有効であることが示唆された。
