    Homegarden commercialization: extent, household characteristics, and effect on food security and food sovereignty in Rural Indonesia

    Homegardens have long been recognized for contributing to household food security, nutritional status, and ecological sustainability in especially poor, rural areas in low-income countries. However, as markets and policies drive the commercialization of food and farming systems, and of rural livelihoods in general, it becomes increasingly difficult for small-holder farmers to maintain homegarden plots. Rather than autonomous spaces to grow food for self-consumption, farmers are transforming the land around their dwellings into an income-generating space by planting commercial crops for sale in urban and processing markets. The objective of this study was to examine homegarden commercialization in the Upper Citarum Watershed of West Java, Indonesia, and its effects on food security and food sovereignty. We employed a mixed-method approach to survey 81 village households involved in agricultural production. For quantitative analysis, we calculated a “homegarden commercialization index,” and developed indicator frameworks to examine relationships between commercialization, household food security, and food-related decision-making. Accompanied by insights from qualitative interviews, our results show that homegardens are highly commercialized, which contributes to the spread of monocultural production in the region. We argue that homegardens should be included and supported in food, agricultural, health, environmental, and rural development policy, in Indonesia and generally.
    Governing Unclear Lines : Local Boundaries as a (Re)source of Conflict in South Sudan
    Justin, Peter Hakim ; Vries, Lotje de - \ 2019
    Journal of Borderlands Studies 34 (2019)1. - ISSN 0886-5655 - p. 31 - 46.
    South Sudan’s administrative boundaries stem from the colonial period. Since it gained independence in 2011, subsequent rounds of reshuffling of the political system, internal borders, and power relations have been a source of confusion, elite manipulation, and conflict throughout the country. This paper explores the impact of this confusion by focusing on multiple shifting linkages between administrative boundaries and identities and shows how the mobilization of ethnic identities has become central to territorial claims and creating territorial borders. We use three local conflicts in Central Equatoria State to illustrate how claims of belonging and entitlement are being used by elites for economic, political, and socio-cultural gains. The three cases also show how such manipulation increases the likelihood of ethnic division and conflict. Following the decision by the government in 2015 to increase the number of states from 10 to 28 in October 2015, further manipulation of borders and identities is likely to occur and could result in more violence, ethnic-based conflict, and human suffering.
    Effect of different microphysics scheme on WRF model : A simulation of hail event study case in Surabaya, Indonesia

    In the present study, the Weather Research and Forecasting (WRF) Model was employed to simulate hail event over Surabaya on 8 March 2017 in term of evaluating sensitivity to four microphysical schemes (WSM3, WSM6, Thompson, and Morrison). The analyzed weather variables were surface parameters (e.g. temperature, air pressure, u-wind component), reflectivity, surface wind field, and hydrometeor particles (e.g. cloud, rain, ice, and graupel) which is compared to observation (e.g. AWS and DWR product). Two main analysis were performed: point-to-point and spatial (e.g. horizontal, vertical, and temporal) analysis. The result was, among surface variables, u-wind component acted significantly different from observation due to boundary condition bias and strong synoptic-scale forcing. This error led model to produce misplaced the storm cloud but appropriate in time. The MORRISON-2 scheme could simulate size and lifetime of convective cloud close to radar observation, but THOMPSON is more able to generate cloud properties in proper condition when hail event is possible to occur. The adding number of concentration only for rain species and let the graupel intercept parameter depend upon its mixing ratio lead this scheme is more robust to simulate mix-phase cloud development. Therefore THOMPSON scheme is more suitable to reproduce cloud convective which more dominated by rain species as a typical of tropical cloud.

    Landreform und Konflikt im Südsudan: Erkenntnisse aus Yei River County

    Agricultural reforms - History - Land law - Nation and state building - Social change - Social conflicts - South sudan

    Following South Sudanese independence in 2011, land reform became a major aspect of state building, partly to address historical injustices and partly to avoid future conflicts around land. In the process, land became a trigger for conflicts, sometimes between communities with no histories of “ethnic conflict.” Drawing on cases in two rural areas in Yei River County in South Sudan, this paper shows that contradictions in the existing legal frameworks on land are mainly to blame for those conflicts. These contradictions are influenced, in turn, by the largely top-down approach to state building, which has tended to neglect changes in society and regarding land resulting from colonialism and civil wars.

    Work orientations of female returners

    Hakim's Preference Theory on the heterogeneity of the work-life preferences of women, and in particular its implicit assumption that a woman's preference to work or to stay at home is based on her personal choices, has frequently been criticized. Other researchers emphasize the constraining influence that a woman's personal, financial and family situation can have on her preferences. Our article aims at contributing to this debate by analysing the work orientations of female returners, in themselves a particular job-seeking category which differs noticeably from other categories in regard to their central motivation when considering whether or not to re-enter a paid job. Our research indicates that older female returners are more job and people oriented than younger ones. Female returners with a lower level of education and female returners with financial problems are money oriented, whereas higher educated female returners and female returners who are financially well off show more of a job orientation. Surprisingly, the presence of young children in the household does not significantly influence the work orientations of female returners.
