    UZBEK-GERMAN FORUM FOR HUMAN RIGHTS E.V. Oppelner str. 48-49 10997 Berlin +49 (0)176 3120 2474 [email protected] www.uzbekgermanforum.org Business & Human Rights Resource Centre Berlin, 22 Januar 2019 Dear Ms Skybenko, On behalf of the Uzbek-German Forum for Human Rights (UGF), I am writing to draw your attention to the systemic use of forced labour by the Uzbek-Spanish joint ventures Maxam-Chirchiq and Ammofos- Maxam, located respectively in the cities of Chirchiq and Almalyk in the Tashkent region of Uzbekistan. Every year, employees from Maxam-Chirchiq and Ammofos-Maxam are forcibly sent to pick cotton for up to two months during the harvest. This often involves living and working in inappropriate conditions, away from their families, with inadequate food, water and sanitary facilities. Employees risk dismissal from their jobs for refusal to pick cotton and many who speak to journalists and human rights activists are unwilling to reveal their names for fear of reprisals by their employers. Our research has found that forced labour at Maxam-Chirchiq and Ammofos-Maxam is not limited to picking cotton. In the summer of 2018, 120 employees of Maxam-Chirchiq were forced to go to the city of Akhangaran every day (located 82 km from Chirchiq) to work on demolishing buildings and clearing construction waste. Employees of Maxam-Chirchiq and Ammofos-Maxam have been forcibly mobilised to harvest cotton every autumn for many years under orders of the Government of Uzbekistan. We are aware of two deaths of employees of Maxam-Chirchiq and Ammofos-Maxam related to work in the cotton fields during the harvests of 2014 and 2018.

Now a number of EU member states, President Karimov has resorted to scapegoating and principally Germany, are pressing to lift or weaken the cosmetic changes, such as the October 2006 firing of sanctions, as early as this month. The Karimov government Andijon governor Saydullo Begaliyev, whom he has has done nothing to justify such an approach. Normalisation publicly called partially responsible for the previous of relations should come on EU terms, not those of year’s events. On the whole, however, Karimov continues Karimov. Moreover, his dictatorship is looking increasingly to deny that his regime’s policies were in any way at fragile, and serious thought should be given to facing the fault, while the same abuses are unchecked in other consequences of its ultimate collapse, including the impact provinces.

  • O'zbekiston Respublikasi Oliy Va O'rta Maxsus Ta'lim Vazirligi Qo'qon Davlat Pedagogika Instituti
    O’ZBEKISTON RESPUBLIKASI OLIY VA O’RTA MAXSUS TA’LIM VAZIRLIGI QO’QON DAVLAT PEDAGOGIKA INSTITUTI “KIMYO VA UNI О‘QITISH METODIKASI” kafedrasi H.U.Dehqonov, S.A.Movlonova KIMYO (5110500-Geografiya o’qitish metodikasi ta’lim yо‘nalishi talabalari uchun о‘quv qо‘llanma) TOSHKЕNT – 2020 Kirish. Kimyo fani mo’jizakor fan. Kimyo fani yutuqlarini har sohada ko’rishimiz mumkin. Kiyib yurgan kiyimimiz, oziq-ovqat mahsulotlari, dori-darmon vositalari, xo’jalik mollari, parfyumeriya sohasi, energetika sohasi va bir qancha sohalarda kimyo fanining o’rni beqiyos. Kimyo fanini o’rganish davomida biz uning qanday fan ekanligini, o’rganilish sohalarini, kimyo fanidagi kimyoviy jarayonlarning reaksiya tenglamalari orqali ifodalanishini o’rganamiz. Hozirgi kunda kimyo fanini o’rganishda kompyuterdan foydalanish, ya’ni demonstratsion tajribalarni kompyuter yordamida tushuntirish talabalarning tasavvur qilish qobiliyatini kengaytirishga xizmat qiladi. Ushbu o’quv qo’llanma pedagogika universitetlarining geografiya o’qitish metodikasi ta’lim yо‘nalishi talabalari uchun tasdiqlangan, kimyo о‘quv dasturi asosida tuzilgan bо‘lib, asosiy maqsad nazariy-amaliy va mustaqil mashg‘ulotlarni talabalar tomonidan osonroq о‘zlashtirilishiga qaratilgan, ayniqsa mustaqil bajariladigan amaliy mashg‘ulotlarni sifatli uyushtirish uchun, talabalarni о‘quv qо‘llanmalar bilan ta’minlash zarur. Hozirgi mavjud qо‘llanmalar asosan rus tilida, о‘zbek tilida chiqqanlari aynan universitet shu yо‘nalish talabalari uchun dastur asosida yozilmagan. Talabalar kurs davomida mustaqil ishlash uchun anorganik birikmalarning nomenklaturasini, tuzilishini, olinish usullarini, fizikaviy va kimyoviy xossalarini sinchkovlik bilan о‘rganishlari talab qilinadi. Buning uchun ular: anorganik moddalar о‘rtasidagi genetik bog‘lanishni, modda molekulasini kimyoviy tuzilishini, elektron tuzilishini, qutblanish va orbitallarni tuzilishini, modda molekulalari о‘rtasidagi boradigan reaksiyalar, reaksiya mexanizmlari, reaksiy turlari, muhitning ta’siri hamda olingan bilimlarni amaliy jihatdan qо‘llay bilishlari kerak.

  • Assessment of Intergovernmental Relations and Local Governance in the Republic of Uzbekistan
    ASSESSMENT OF INTERGOVERNMENTAL RELATIONS AND LOCAL GOVERNANCE IN THE REPUBLIC OF UZBEKISTAN Prepared for Prepared by Peter Epstein Matthew Winter With Munira Aminova Andrei Makarikhin Central Asian Republics Local Government Initiative Phase II Clare Romanik United States Agency for International Development Contract No. EEU-I-00-99-00015-00, Task Order No. 811 The Urban Institute February 2004 UI Project 06901-017 THE URBAN INSTITUTE 2100 M Street, NW Washington, DC 20037 (202) 833-7200 www.urban.org ACKNOWLEDGEMENTS Preparation of this report has drawn on a variety of primary and secondary sources. It could not have been completed without the patient, often surprisingly frank assistance of many experienced Uzbekistanis working both inside and outside of government to whom we are most grateful for their time, information, and insights. Indeed, most information provided in this assessment has been gleaned from interviews with these local observers, though in most cases the authors endeavored to verify each fact at more than one interview. In the body of the assessment, the authors have indicated where specific information is based on interviews with a small number of people. In respect to secondary sources, the chapter on Uzbekistan written by Kuatbay Bektemirov and Eduard Rahimov as a contribution to the Open Society Institute’s Local Governments in Eastern Europe, in the Caucasus and Central Asia: Developing New Rules in the Old Environment served as a valuable point of departure for understanding the complexities of local government in Uzbekistan, which we have sought to elaborate further in this assessment. The present authors’ understanding of the structure of intergovernmental finance in the country benefits from Alex MacNevin’s July and October 2003 reports for Bearing Point on building oblast level revenue capacity and a draft works in progress by the Center for Economic Research in Tashkent.
