مطالعه عوامل موثر بر حفاظت از تنوع زراعی برنج(oryza sativa) در جهت تامین امنیت غذایی پایدار خانوارهای بندر انزلی، استان گیلان

با افزایش جمعیت، ضرورت تامین امنیت غذایی، امری آشکار است. بدین منظور تک کشتی گونه‌های اصلی تامین‌کننده غذا، مانند برنج (oryza sativa)  درراس اهداف کشاورزان قرار گرفته است. ضرورت حفاظت از تنوع زیستی کشاورزی به‌منظور تامین امنیت غذایی پایدار ضروری است. مطالعه‌ای در شمال ایران که کشاورزان در آنجا اغلب تک کشتی برنج دارند، در دو مرحله با استفاده از پرسشنامه انجام شده است. مرحله اول؛ 90 خانوار به‌صورت تصادفی انتخاب شد و در مورد مولفه‌های امنیت غذایی، کفایت، سلامت، مانند کفایت غذایی، سلامت، مغذی بودن، دسترسی، زندگی سالم و فعالیت‌های مناسب مصاحبه گردید. مرحله بعد، عوامل موثر در حفاظت از تنوع زراعی، در پنج گروه اقتصادی، اجتماعی، آموزشی، زیرساختی و سازمانی قرار گرفت. در نهایت، از نرم‌افزار spss برای تحلیل آماری و از ضریب همبستگی پیرسون به‌منظور تعیین میزان و جهت رابطه بین متغیرها استفاده شده است. نتایج نشان می‌دهد که 43.22 درصد افراد دارای امنیت غذایی و بقیه افراد در ناامنی غذایی به سر می‌برند که ناامنی غذایی به سه دسته گرسنگی متوسط با 11.56 درصد، گرسنگی کم با 26.5 درصد و گرسنگی شدید با 18.66 درصد تقسیم می‌شود که به‌ترتیب دارای کفایت غذایی، دسترسی به مواد غذایی، فعالیت سالم است، امّا از لحاظ زندگی سالم به دور از بیماری، مغذی بودن و سلامت غذایی ضعیف می‌باشد. عوامل آموزشی و زیرساختی بیشترین تاثیر را در حفاظت از تنوع زراعی توسط کشاورزان دارد که عدم آگاهی اثر منفی و بهبود زیر ساخت اثر مثبت دارد.

study of effective factors for the protection of rice(oryza sativa) crop diversity to provide security, food, and sustainable households in bandar anzali, guilan province

introduction by 2050, the world's population is estimated to increase by 30 to 35 percent, so about 60 percent growth in agricultural production must be achieved for proper nutrition. food security refers to a situation in which people at all times, physically, socially, and economically, have access to adequate, safe, and nutritious food that meets their nutritional needs and preferences for an active and healthy life. one of the most important challenges of the 21st century to improve food security is the preservation of agricultural biodiversity. biodiversity is a key factor in ensuring that adequate food is available at any given scale and is often assessed in terms of genetic composition and local stability. conventional single-crop farming systems depend on a small number of high-yield crops, and their expansion, in addition to environmental problems, led to significant reductions in plant biodiversity. there are different approaches to addressing food security and biodiversity protection concerns. this study aimed to investigate food security and effective factors in protecting agricultural biodiversity to ensure sustainable food security. materials and methods this research has been performed in anzali port. the present study is applied in terms of purpose and descriptive-analytical method. this study was conducted in two stages: 1. food security status: information required for research through library and documentary studies (detailed results of the country's census and village identity) and part of it through field studies (observation, interview, and questionnaire). in this regard, a questionnaire related to food security indicators such as food adequacy, health, nutrition, and availability to have an active and healthy life was used in the first stage. randomly selected ,a total of 90 households in the city were interviewed. 2. study of the role of agriculture. biodiversity conservation indicators in ensuring sustainable food security: 100 farm managers were surveyed in 10 villages, and the questions were divided into five groups: economic, social, educational, infrastructure, and organizational. finally, spss software and pearson correlation were used to plot the chart and statistical analysis. results and discussion the city has food adequacy, access to food, and healthy activity, which is about 8 hours a day, but it is poor in terms of healthy living away from disease, nutrition, and having a healthy food free of chemical inputs. improving food security is especially important for developing countries where social, political, cultural, and economic developments can improve food security. the government should adopt policies such as global cash food subsidies to improve food security, direct support for low-income households, and allocate subsidies based on the geographical location of these households. our results show that even in a city, the relationship between socioeconomic factors and caloric intake can vary from region to region. thus, if governments choose specific policies (for example, education policies), they should target provinces where food security is negatively correlated with calorie intake. simple income-raising policies are not always effective in improving calorie intake in rural areas. relevant and private government institutions should focus on other socio-economic factors and prioritize them in improving calorie intake in the family and improving health outcomes. in all villages except the exempt village, infrastructure factors have the greatest impact on maintaining biodiversity, and economic factors have the greatest impact in the exempt village. the highest standard deviation is seen in the infrastructure factors related to torbegodeh, talebabad, shilehsar, khomeyran, ashpala, abkenar, and kapurchal villages. the most standard deviation in other villages is related to economic factors. in torbegodeh and rudpasht villages, the importance of educational factors; talebabad, shileh sar, and kapurchal villages, the importance of social factors; khomeyran, maaf, and ashpala villages, the importance of infrastructure factors; and abkenar village, environmental factors are more. conclusion in general, in this region, rice fields with high inputs of resources and low crop diversity and environmental impacts can lead to environmental feedback in different areas, for example, reducing biodiversity and soil fertility, which is more dependent on the base. fossil fuel inputs for robust production stability. to this end, focusing on ofproducing agricultural products for domestic consumption to increase food security by supporting rural livelihoods and producing environmentally sustainable food should be a priority.
