“…Similarly, Nazareth et al (2018) used agricultural productivity projections for different regions of Brazil -obtained from Assunção & Chein (2016) -and for other regions of the world to assess their economic impacts for the country and the rest of the world using a dynamic global CGE model for 5 regions of Brazil and 7 other regions that cover the rest of the world. Tanure et al (2020) also used the projections of agricultural productivity loss for the period 2030 to 2049 generated by Assunção & Chein (2016) to analyze the economic impacts of climate change on the region of the Legal Amazon with the use of an interregional CGE model with recursive dynamics. It is noteworthy, however, that there is still a strong limitation for studies of this nature for Brazil, which is the lack of estimates of future agricultural productivity for different agricultural crops covering the entire national territory, as required by the interregional CGE models, predominantly employed in these types of studies for the country.…”

Resumo: Este artigo investiga os impactos socioeconômicos potenciais que as mudanças climáticas projetadas para 2040 podem ter sobre a agricultura e a economia brasileira nas suas diferentes regiões. Para isso, é usado um modelo de EGC inter-regional dinâmico recursivo, calibrado para o ano de 2010. São considerados dois cenários de mudança climática: um Intermediário (RCP4.5) – menos severo – e outro Pessimista (RCP8.5) – mais severo. A principal distinção em relação aos estudos anteriores para o Brasil é o uso de estimativas de perda de área apta para culturas agrícolas, baseadas em projeções para o padrão regional de mudanças climáticas do 5º relatório do IPCC (o mais recente). Os resultados sugerem que as mudanças climáticas deverão provocar retração no PIB real do Brasil em ambos os cenários, mas esta deverá ser mais intensa no cenário Intermediário; sinalizam também que as perdas serão maiores para as famílias mais pobres e para as regiões cuja economia é mais dependente da agricultura, em particular do cultivo da soja, e que o consumo real e o bem-estar das famílias da região Centro-Oeste e parte do Nordeste (onde a cultura da soja é mais representativa) serão mais afetados do que em outras regiões do Brasil.

“…The impacts of climate change have increased population poverty levels, reduced employment and income opportunities, reduced individual livelihood diversification and increased emigration [26,27]. On the other hand, due to lower production and employment, [28] show a negative effect on agricultural GDP in the Legal Amazon. A study conducted by [29] on small-scale coffee farms in Mexico reveals that rainfall variability impacted farmers' incomes and made agricultural activities no longer viable.…”

Socio-Economic Implications and Potential Structural Adaptations of the Tunisian Agricultural Sector to Climate Change

et al. 2021

Climate change is expected to have serious economic and social impacts on Tunisian rural farmers. The extent of these impacts will largely depend on the level of political and structural adaptations. This study aims to evaluate the effect of increasing water shortages on agricultural income and employment. It also analyzes structural adaptation strategies implemented by farmers in response to this challenge. We have therefore developed a regionally disaggregated supply model to simulate three types of scenarios concerning (i) decreasing quantities of irrigation water at the regional level; (ii) enhanced irrigation water use efficiency; and (iii) higher production prices. Observed crop production data for 21 crops and 24 districts of Tunisia have been used. Districts have been aggregated into five regions based on bioclimatic homogeneity. Results show that climate change will lead to the reduction of irrigated areas and an increased importance of rainfed agriculture. It will also have a negative impact on farm income and employment. This negative effect can be fully mitigated by improving water use efficiency, at farm and perimeter levels, and can be reversed by offering more attractive producer prices to farmers through enhanced value chain integration.

Pestisida kimia yang sering digunakan petani untuk mengatasi hama mempunyai dampak negatif bagi lingkungan dan kesehatan manusia. Salah satu alternatif pengganti pestisida kimia adalah pestisida organik. Beberapa tanaman potensial sebagai pestisida organik adalah bawang putih dan umbi gadung. Salah satuhama yang merugikan bagi tanaman cabai adalah jangkrik. Penelitian ini bertujuan untuk membandingkan pestisida organik dari bawang putih dan umbi gadung dalam mengatasi hama jangkrik pada tanaman cabai. Penelitian diawali dengan pembuatan habitat tiruan jangkrik dari tanaman cabai, kemudian diadaptasikan selama tiga hari. Sebanyak 30 tanaman cabai dikelompokkan menjadi 10 perlakuan yaitu aquades sebagai aquades sebagai kontrol negatif, pestisida kimia sebagai kontrol positif, ektrak bawang putih dan ekstrak umbi gadung dengan konsentrasi masing-masing 5%, 10%, 20% dan 40%. Perbandingan efektifitas antar perlakuan diamati melalui tiga aspek antara lain nilai persentase mortalitas, indeks kecepatan kematian dan medium lethal time (LT50). Hasil dari pengamatan menunjukkan bahwa perlakuan berpengaruh nyata terhadap nilai ketiga aspek. Semakin tinggi konsentrasi semakin efektif dalam membunuh jangkrik. Nilai persentase mortalitas, indeks kecepatan kematian dan medium lethaltime (LT50) tertinggi pada ekstrak umbi gadung 40% adalah 85%, 50 dan 6,5 menit dan ekstrak bawang putih 40% adalah 55%, 31 dan 10 menit secara berurutan. Berdasarkan analisis ketiga aspek tersebut ekstrak umbi gadung lebih efektif sebagai pestisida organik dibandingkan dengan ekstrak bawang putih dengan nilai yang mendekati kontrol positif.
