“…This influence was observed to be higher in rainfed production environments. Fertilizer subsidies have been shown to beneficially impact paddy yields in Sri Lanka (Kumar & Sharma, 2013; Perera et al ., 2016; Walisinghe et al ., 2017; Wijetunga & Saito, 2017; Ranathilaka & Arachchi, 2019; Chandrasiri et al ., 2020). As a major input of production, fertilizer subsidies assure economic benefits to farmers and motivate them to perform other managerial operations, making harvesting feasible.…”

This study highlighted the severity of paddy harvest failure under various water regimes by elaborating on spatiotemporal variations, and estimating the influence of climatic variation on such crop failure in Sri Lanka. A panel data set obtained from 18 districts from 1981 to 2019 was analysed. The Unharvest Index (UI) (i.e., an index that was developed to measure the intensity of crop failure) was estimated according to seasonal water regimes for each district. The panel data regression method was used for analysis. On average, 5 per cent of areas planted for paddy was unharvested annually, fluctuating with the coefficient of variation at 60 per cent with remarkable spatial variation. Harvest failure was more prominent in rainfed production as compared to irrigated cultivation; in dry and intermediate zones as opposed to wet zones; and in the Maha season (October to March) rather than the Yala season (April to September). Climate variability during the crop season significantly altered UI, especially during the early growth phase (Growth Phase I) as compared to the later growth phase (Growth Phase II). Temperature variability increased UI in rainfed production; an increase in the number of days above optimum temperature in Growth Phase I affected UI in minor irrigation; higher rainfall during Growth Phase I reduced UI in rainfed production; and higher rainfall variation reduced UI under all water regimes. Our findings suggest the importance of formulating localized climate‐smart adaptation policies and specific crop insurance programs for rainfed paddy production.

“…Penelitian ini tidak berbeda jauh dengan penelitian Pace et al (2017), bahwa ada sinergi antara kebijakan subsidi pupuk dan kebijakan cash transfer kepada petani miskin. Selain itu menurut Perera et al (2016), cash program lebih disukai daripada subsidi dalam bentuk natura karena produksi keseluruhan diperkirakan akan meningkat jika pemerintah memberikan transfer uang tunai yang setara dengan nilai subsidi pupuk. Sejalan dengan itu, menurut Susilowati (2016) dengan melaksankan opsi kebijakan kenaikan HET secara bertahap, maka selama lima tahun (2016 -2020), jumlah penghematan APBN yang berasal dari subsidi pupuk ini akan mencapai antara 85 hingga 99 triliun rupiah.…”

Kebijakan pertanian dan program perlindungan sosial diperlukan untuk meningkatkan kesejahteraan dan menurunkan kemiskinan rumahtangga pertanian, tetapi sedikit perhatian diberikan kepada interaksi kedua kebijakan. Penelitian bertujuan untuk membangun model ekonomi rumahtangga petani usaha padi penerima PKH dan menganalisis dampak kebijakan pertanian, program perlindungan sosial, dan integrasi kedua kebijakan terhadap kinerja ekonomi dan kesejahteraan rumahtangga pertanian, serta pengaruhnya terhadap jumlah penduduk miskin di Kabupaten Karawang. Penelitian menggunakan data cross section pada 158 rumahtangga petani padi penerima PKH. Model dibangun sebagai sistem persamaan simultan yang terdiri dari 18 persamaan struktural dan 22 persamaan identitas. Estimasi model menggunakan metode two-stage least squares (2SLS). Hasil menunjukkan bahwa model yang dibangun dapat diaplikasikan kemampuannya untuk melakukan simulasi kebijakan dan dapat digunakan untuk mengevaluasi alternatif dampak kebijakan yang relevan terhadap kesejahteraan rumahtangga petani. Sedangkan hasil analisis menunjukkan bahwa PKH dapat berguna untuk mengkompensai kesejahteraan yang hilang sebagai akibat kebijakan pertanian berupa pengurangan subsidi pupuk serta merupakan instrumen yang dapat disinergikan dengan kebijakan pertanian.
