Changes in agricultural yields due to climate change will affect land use, agricultural production volume, and food prices as well as macroeconomic indicators, such as GDP, which is important as it enables one to compare climate change impacts across multiple sectors. This study considered five key uncertainty factors and estimated macroeconomic impacts due to crop yield changes using a novel integrated assessment framework. The five factors are (1) land-use change (or yield aggregation method based on spatially explicit information), (2) the amplitude of the CO2 fertilization effect, (3) the use of different climate models, (4) socioeconomic assumptions and (5) the level of mitigation stringency. We found that their global impacts on the macroeconomic indicator value were 0.02–0.06% of GDP in 2100. However, the impacts on the agricultural sector varied greatly by socioeconomic assumption. The relative contributions of these factors to the total uncertainty in the projected macroeconomic indicator value were greater in a pessimistic world scenario characterized by a large population size, low income, and low yield development than in an optimistic scenario characterized by a small population size, high income, and high yield development (0.00%).

Food Security And Nutrition

In the last five years, the world's attention has shifted to food security in relation to climate change adaptation and mitigation, particularly in 2008, when food prices skyrocketed, causing famine in Cape Africa and even the Sahel, which is still feeling the effects of this famine in 2012. In the same year, the OHCHR report (the Office of the United Nations High Commissioner for Human Rights) notes the need to safeguard food security and nutrition in the context of Human Rights. A major shift occurred in Indonesian agriculture due to the 1999 eruption of Mount Elanor. A focus on climate influences has been a prominent component of the Indonesian government's policy regarding agriculture for some time. Plant-resistant crops or programs for mitigating climate change take the form of either of these options. Culminating a significant development in policies to secure food security, such as protection of agricultural land, various policies were created to evaluate land use and regulations of the Minister of Agriculture pertaining to guidelines for land use. The study, which was done for a period of six months, has a goal of learning more about the Banjar people's local knowledge on climate change. By collecting data from locals, such as farmers, community leaders, and village heads, who have detailed knowledge about Banjar customs and traditions, and from Banjar people who are selected for the research in Banjar Regency, South Kalimantan, qualitative methods and collection of local knowledge and local wisdom strategies were employed.

Climate change (CC) and its impacts on the socio-economy and the development of communities has become an issue causing very special concern. The rise in global temperatures, in sea levels, extreme weather phenomena, and salinization have occurred more and more and have directly influenced the livelihoods of rural households in the Red River Delta – one of the two regions projected to suffer strongly from climate change in Vietnam. For farming households in this region, the major and traditional livelihoods are based on main production materials as agricultural land, or aquacultural water surface Changes in the land use of rural households in the Red River Delta during recent times was influenced strongly by the Renovation policy in agriculture as well as the process of industrialization and modernization in the country. Climate change over the past 5 years (2005-2011) has started influencing household land use with the concrete manifestations being the reduction of the area cultivated and the changing of the purpose of land use.

Participatory Observation

Penelitian ini menguji teori Marx yang mengatakan bahwa dalam proses kapitalisasi, petani lahan kecil akan tergusur oleh petani lahan besar. Penelitian ini menggunakan pendekatan kualitatif dengan metode Participatory Action Research (PAR). Menggunakan teknik observasi partisipasi di lapangan, studi ini melakukan wawancara mendalam terhadap petani. Analisis data yang digunakan bersifat induktif. Penelitian ini menghasilkan kesimpulan, bahwa teori Marx tidak terjadi di malar Aman. Adapun penyebab menurunnya pertanian disebabkan menurunnya unsur hara tanah, mahalnya biaya produksi, alih fungsi lahan dan perubahan cuaca. Sedangkan strategi petani lahan kecil untuk mempertahankan kehidupan yaitu melakukan pola tanam tumpang sari, melakukan pekerjaan tambahan, dan mengatur keuangan.This study examines Marx's theory which says that in the process of capitalization, small land farmers will be displaced by large land farmers. This study uses a qualitative approach with the method of Participatory Action Research (PAR). Using the techniques of participatory observation in the field, the study conducted in-depth interviews on farmers. Analysis of the data used is inductive. This study led to the conclusion that Marx's theory does not happen in Aman malar. The cause of the decline of agriculture due to declining soil nutrients, the high cost of production, land use and climate change. While the strategies of small land farmers to sustain life is to do the planting patterns of intercropping, do extra work, and manage finances.

To get more insight in the environmental performance of the Suiker Unie beet sugar, Blonk Consultants performed a comparative Life Cycle Assessment (LCA) study on beet sugar, cane sugar and glucose syrup. The system boundaries of the sugar life cycle are set from cradle to regional storage at the Dutch market. For this study 8 different scenarios were evaluated. The first scenario is the actual sugar production at Suiker Unie. Scenario 2 until 7 are different cane sugar scenarios (different countries of origin, surplus electricity production and pre-harvest burning of leaves are considered). Scenario 8 concerns the glucose syrup scenario. An important factor in the environmental impact of 1kg of sugar is the sugar yield per ha. Total sugar yield per ha differs from 9t/ha sugar for sugarcane to 15t/ha sugar for sugar beet (in 2017). Main conclusion is that the production of beet sugar at Suiker Unie has in general a lower impact on climate change, fine particulate matter, land use and water consumption, compared to cane sugar production (in Brazil and India) and glucose syrup. The impact of cane sugar production on climate change and water consumption is highly dependent on the country of origin, especially when land use change is taken into account. The environmental impact of sugar production is highly dependent on the co-production of bioenergy, both for beet and cane sugar.
