Millions of people in Sunderbans generate their livelihood and sustenance through fishing, honey collection, fuel wood and timber. The paper attempts to examine the issues of coastal poverty, food security as well as livelihood insecurity and the adaptation options that help to the resilience of climate change. The paper is based on field survey conducted in the villages of Sunderans in 2011. The study revealed that fishing and crab collection, honey collection are the important sources of livelihood. The fishing resources have been declining which leads to the insecurity of livelihoods of the fishing communities. The study has identified the key adaptations like dependency of money lenders, fishing and crab collection, formation of Self Help Groups, livestock rearing and migration. This paper has important policy implications for poverty, livelihood vulnerability and migration.

Climate change is expected to significantly influence Indonesian rice production as this phenomenon will exacerbate extreme climate events such as El Nino and La Nina which have caused serious loss in rice production. This paper is attempted to propose plausible climate change adaptations for rice production by examining the formal documents on climate change studies in Indonesia and rice development strategies and to investigate their linkage with the Sustainable Development in Indonesia. The result shows that climate change adaptations will support Indonesian rice development strategies through options of “change cropping pattern/modified planting season” which has not been addressed by the development strategies. The proposed adaptations which are directed through two major programs for increasing rice production called as Extensification and Intensification, have also already addressed the four pillars of Indonesian sustainable development, namely: pro-job, pro-poor, pro-growth and pro-environment.

Abstract The changing climate affects natural resources that impart a negative impact on crop yield and food security. It is thus imperative to identify agro-climate wise, area-specific adaptation options to ensure food security. This study, therefore, evaluated some feasible adaptation options for two staple food grain crops, rice and wheat, in different agro-climatic regions (ACRs) of Eastern India. Alteration in transplanting date, seedling age, and fertilizer management (rate and split of fertilizer) for rice; and sowing date, fertilizer management, and deficit irrigation scheduling for wheat, are assessed as adaptation options. Crop environment and resource synthesis (DSSAT) model is used to simulate the crop yield using different plausible adaptation options to projected climate scenarios. Findings show that shifting transplanting/sowing date, and nitrogen fertilizer application at 120% of recommended nitrogen dose with four splits could be an effective adaptation for rice and wheat crops. Results also emphasize that transplanting of 18 days older seedlings may be beneficial in rice cultivation. In contrast, irrigation at a 30–40% deficit of maximum available water would sustain the wheat yield under climate change conditions. This study suggests the best combination of adaptation options under climate change conditions in diverse ACRs, which may assist agriculturists in coping with climate change.

AbstractProfitability of rice production in different production systems in Ebonyi State, Nigeria was evaluated. Rice is critical for food security in Nigeria, hence, farmers need to make appropriate choices of rice production systems to optimize production and ensure an adequate domestic supply. This study used 2015 survey data from rice farming households. Rice farmers in swamp, lowland and upland rice production systems showed variability in profit. Swamp production systems had the highest return per hectare (29.37%) followed by lowland production systems (20.10%) and upland production systems (13.03%). Poor access to production credit and climate change were constraints to rice production in the area. Rice production using the swamp production system is profitable and would ensure increased production and higher returns to the farmers. It is recommended that farmers should form cooperative groups to enable them to pool resources together to boost their production.

Systems Thinking Approach

Abstract. Vietnam is a major rice producer and much of the rice grown is concentrated in the Red River Delta (RRD) and the Mekong River Delta (MRD). While the two mega-deltas are highly productive regions, they are vulnerable to natural hazards and the effects of human related environmental change. The natural hazards that affect Vietnam include typhoons, floods and droughts while the major anthropogenic developments happening in Vietnam include dike development, sand mining, dam construction and groundwater extraction. Outbreaks of pests and diseases are also common. Although there is a substantial volume of work investigating the environmental impacts of these natural hazards and anthropogenic interventions, few studies have examined the implications of these on food security. To show that the processes and issues affecting food security are reinforcing and interdependent, we used a systems thinking approach to represent the ways in which natural hazards, anthropogenic land-use and climate change affect rice production in the two mega-deltas. A key finding is that anthropogenic developments meant to improve agricultural productivity or increase economic development create many unwanted environmental consequences such as an increase in flooding, saltwater intrusion and land subsidence which in turn create other negative feedbacks on rice production and quality. In addition, natural hazards may amplify the problems created by human activities. In future, besides creating new environmental threats, climate change may exacerbate the effects of natural hazards by increasing the frequency and severity of natural disasters. Our meta-analysis highlights the ways in which a systems thinking approach can yield more nuanced perspectives to tackle complex and interrelated environmental challenges. Given that mega-deltas worldwide are globally significant for food production and are highly stressed and degraded landscapes, a systems thinking approach can be applied to provide a holistic and contextualized overview of the threats faced in each location.

Climate change is an important issue now-a-days. Global warming i.e. climate change causes sea level rise and that affect the coastal agricultural areas of Bangladesh. The net-cropped area of eastern coastal zone in Bangladesh has been decreasing over the years due to various purposes and the most common one is the land inundation and salinity intrusion by tidal water. The main aims of the study is to assess the change in climatic conditions particularly temperature, rainfall and agricultural land use change in the past and future. Past rainfall, temperature and salinity data have been used to assess the climatic and salinity conditions of the area under investigation. Normalized difference vegetation Index (NDVI) and False Color Composite (FCC) of digital Land sat images have been used to identify land use pattern and Boro rice coverage area. During last 31 years (1978 -2009) 31% rice production land has converted to shrimp culture and salt farming. Salinity intrusion is one of the major causes of agricultural land use change. Salinity level has increased dramatically in dry season during last decade due to increase of temperature, low rainfall pattern, high evaporation rate and low water discharge to the river systems. Future landuse has been projected for 2039 by Markov Model. Result shows that rice production area will decrease rapidly due to salinity intrusion as well as climate change which may threat for food security of Bangladesh. Hereafter, the Government of Bangladesh, national and international institutions will have to work together for minimizing the effect of climate change for food security.
