“…Similarly, in some scenarios, the Gini coefficient may be small due to the number of objectives being considered: if just one individual’s objective is perfectly optimised, and all others are ignored, then G =1 – 1/ n , where n is the number of objectives. The coefficient has been used to estimate regional inequalities in the risk of veterinary epidemics (Li et al (2020)), geographical variability in STD incidence (Elliott et al (2002)) and in ecology to evaluate management programmes and agricultural productivity (Li et al (2017), Zaffaroni & Bevacqua (2022)). The Gini coefficient for a given scenario i is calculated by (Dorfman (1979), Zaffaroni & Bevacqua (2022)): where n is the number of objectives considered and x j,i and x z,i are the values of the objectives for scenario i .…”

“…Members of the public often wish to minimise their infection risk, whilst governments may want to optimise the allocation of vaccines to protect the most vulnerable (Gavish & Katriel (2022)). Similarly, in the context of plant epidemics, growers faced with crop disease will want to maximise profits, but with this comes potential environmental damage (Zaffaroni & Bevacqua (2022)) or reduced profitability when there is no risk of infection (Vyska et al (2016)). The control mechanism adopted by growers may also have negative consequences for others; Grogan & Goodhue (2012) found that when growers sprayed pesticides within their non-citrus fields, the pesticides killed parasitic wasps that are the natural enemy of pests in neighbouring citrus fields.…”

“…Pareto fronts have been calculated to visualise the trade-offs involved in the recent coronavirus pandemic (Yousefpour et al (2020)), to retrospectively evaluate responses to the 1918 influenza pandemic (Velde (2022)) and to better understand how to optimally allocate healthcare equipment during an epidemic (Donmez et al (2022)). In plant disease modelling, they have been used to investigate the trade-offs between crop productivity and environmental impacts (Zaffaroni & Bevacqua (2022)). None of the solutions in the Pareto front is inherently better than any other, so the decision-maker must decide which option to use based on additional information.…”

Expanding growers’ choice of disease management options can promote suboptimal social outcomes

Previous models of growers' decision-making during epidemics have unrealistically limited disease management choices to just two options. Here, we expand previous game-theoretic models of grower decision-making to include three control options: crop that is either tolerant, resistant, or susceptible to disease. Using Tomato Yellow Leaf Curl Virus (TYLCV) as a case study, we investigate how growers can be incentivised to use different control options to achieve socially-optimal outcomes. To do this, we consider the efforts of a "social planner" who moderates the price of crops. We find that subsidising tolerant crop costs the social planner more in subsidies, as its use encourages selfishness and widespread adoption. Subsidising resistant crop, however, provides widespread benefits by reducing the prevalence of disease across the community of growers, including those that do not control, reducing the number of subsidies required from the social planner. We then use Gini coefficients to measure equitability of each subsidisation scheme. This study highlights how grower behaviour can be altered using crop subsidies to promote socially-optimal outcomes during epidemics.

“…Sementara itu, produksi pertanian utamanya tanaman pangan tidak berbanding lurus dengan jumlah permintaan. Keberlanjutan produksi pertanian tanaman pangan menjadi hal yang wajib untuk terpenuhi (Anghinoni et al, 2021;Song et al, 2022), karena menyangkut kelangsungan hidup manusia karena merupakan sumber makanan utamanya (Zaffaroni & Bevacqua, 2022).…”

Pertambahan penduduk sejatinya harus juga dibarengi dengan pertambahan jumlah produksi untuk menjaga agar kebutuhan pangan masyarakat tetap terjaga. Penelitian ini dilaksanakan dengan maksud untuk mengevaluasi kesesuaian lahan serta menentukan alternatif perencanaan penggunaan lahan untuk pengembangan tanaman jagung, ubi kayu dan kacang tanah di Kecamatan Poleang Timur. Penelitian ini menggunakan metode survei bebas didasarkan pada unit lahan. Prosedur pelaksanaan survei tanah dilaksanakan dalam beberapa tahap meliputi tahap persiapan, tahap operasi lapangan dan tahap analisis sampel di laboratorium. Perencanaan penggunaan lahan dilakukan berdasarkan evaluasi kemampuan lahan dan besarnya bahaya erosi. Hasil penelitian menunjukkan bahwa pengembangan tanaman pangan di Kecamatan Poleang Timur Kabupaten Bombana sesuai untuk dikembangkan khususnya jagung seluas 5271,29 ha (78,04%), ubi kayu seluas 4872,34 ha (72,14%) dan kacang tanah seluas 5020,77 ha (74,33%). Alternatif arahan pengelolaan lahan untuk pengembangan tanaman pangan khususnya jagung, ubi kayu dan kacang tanah di Kecamatan Poleang Timur Kabupaten Bombana dilakukan pada tingkat sedang berupa pemupukan untuk faktor penghambat ketersediaan hara, penambahan bahan organik dan pengapuran untuk perbaikan faktor penghambat retensi hara, bahaya erosi diatasi dengan usaha konservasi tanah seperti penanaman sesuai kontur, pembuatan teras dan penanaman tanaman penutup tanah, pembuatan saluran irigasi/pengairan untuk penghambat ketersediaan air. Diharapkan dengan adanya penelitian ini mampu memberikan sumbangsih pemikiran dan sebagai bahan pertimbangan untuk pemerintah daerah setempat dalam hal penyusunan kebijakan serta untuk masyarakat dalam usaha pengembangan tanaman pangan.
