The Impact

Maintaining a certain amount of agricultural land and promoting its agricultural land utilization efficiency is essential in a country. Many innovative strategies for adapting to climate change have been implemented in developed countries. To achieve the goal of climate change adaptation for agricultural land, a vulnerability assessment of farmland is indispensable. Based on the research framework of the Intergovernmental Panel on Climate Change, this study applied the structure of exposure, sensitivity, and adaptation to build criteria and conduct an evaluation of a designated area in Southern Taiwan. We identified the key factors of the vulnerability of farmland, through mapping with spatial analysis, and by using geographic information system tools. The main purpose of the application of a vulnerability assessment is not to explicitly describe the status of agricultural land to climate change, but to help local government and farmers to identify the critical area, and to discuss the appropriated adaptive policies. According to the results of the vulnerability assessment of agricultural land, the entire study region can be divided into three patterns: Pattern 1, located in the western coastal zone, filled with various attributes of high vulnerability; Pattern 2, distributed on the central plain region in the east, with complete blocks of agricultural land and low vulnerability; and Pattern 3, located in the central plain region to the west, a region in which areas with various vulnerability levels. The following three types of adaptation strategies for climate change for farmland were established: (1) the enhancement of agricultural production, (2) the maintenance of agricultural production, and (3) the conservation of the agricultural environment. The current results can serve as valuable guidelines for governments to implement feasible local adaptation strategies in the future.

Purpose Farmers' adaptation strategies in agricultural production are required to minimise the negative impact of climate change on a nation's food production in developing countries. Based on the panel data of the provincial level in China from 2000 to 2017, this study aims to analyse the changing climate over recent years and farmers' adaptation strategy in terms of cropping in agricultural production. Design/methodology/approach This study uses Simpson's diversity index (SDI) to measure the degree of crop diversity planted by farmers and evaluate the influence of climate change on farmers' cropping strategy using the fixed-effect model. Further, the authors estimate the impact of farmers' cropping strategy on their economic performances in two aspects including yields and technical efficiency of crops. Findings The empirical results show that the overall climate appears a warming trend. Different from farmers in some other countries, Chinese farmers tend to adopt a more specialised cropping strategy which can significantly improve the technical efficiency and yields of crops in agriculture. In addition, as a moderating role, the specialised cropping can help farmers to alleviate the negative impact of climate change on technical efficiency of their crops. Originality/value First, previous studies showed that the changing climate influenced farmers' adaptation strategies, while most studies focussed on multiple adaptation strategies from the farm-level perspective rather than cropping strategy from the nation-level perspective. Second, the present study investigates how the cropping strategy affects the economic performance (in terms of the technical efficiency and crop yields) of agricultural production. Third, the stochastic frontier analysis method is used to estimate the technical efficiency. Fourth, this study explores the moderating effect between farmers' cropping strategy and technical efficiency by introducing an interaction item of SDI and accumulated temperature.

Climate Change Adaptation Strategies

<p>The Peruvian Andes are a hotspot of vulnerabilities to impacts in water resources due to the propensity for water stress, the highly unpredictable weather, the sensitivity of glaciers, and the socio-economic vulnerability of its population. In this context, we selected the Vilcanota-Urubamba catchment in Southern Peru for addressing these challenges aiming at our objectives within a particular hydrological high-mountain context in the tropical Andes: a) Develop a fully-distributed, physically-based glacier surface energy balance model that allows for a realistic representation of glacier dynamics in glacier melt projections; b) Design and implement a glacio-hydrological monitoring and data collection approach to quantify non-glacial contributions to water resources and the impact of catchments interventions; c) Mapping of human water use at high spatiotemporal resolution and determining current and future levels of water (in)security; and d) Integrate last objectives in a glacier - water security assessment model and evaluate the tool's capacity to support locally embedded climate change adaptation strategies. </p><p>The RAHU project intends to transform the scientific understanding of the impact of glacier shrinkage on water security and, at the same time, to connect to and inform policy practices in Peru. It follows a "source to tap" paradigm, in which is planned to deliver a comprehensive and fully integrated water resources vulnerability assessment framework for glacier-fed basins, comprising state-of-the-art glaciology, hydrology, water demand characterisation, and water security assessment. It includes glacio-hydrological and water resources monitoring campaigns, to complement existing monitoring efforts of our project partners and collaborators, and new remotely sensed data sets. Those campaigns will be implemented using the principles and tools of participatory monitoring and knowledge co-creation that our team has pioneered in the tropical Andes. The datasets produced by this approach, combined with existing monitoring implemented by our team and collaborators, will allow us to build an integrated water supply-demand-vulnerability assessment model for glacierized basins, and to use this to evaluate adaptation strategies at the local scale. </p><p>This research is part of the multidisciplinary collaboration between British and Peruvian scientists (Newton Fund, Newton-Paulet).</p>

The Impact

India is a large country with all types of climates and different kinds of soil requiring different types of farming. Most of the agricultural land in India is dependent on rainfall for irrigation. India has about 15 Agro-climatic zones with different types of farming methods and crops. As most of the population is dependent on agriculture and two-third of the country depend on monsoon rains to aid in agriculture, any change in frequency of the rains will affect these areas critically. Assessment of the effects of global climate changes on agriculture might help to properly anticipate and adapt farming to maximize agricultural production. At the same time agriculture has been shown significant effects on climate change, primarily through the production and release of greenhouse gases such as carbon dioxide, methane, and nitrous oxide. The impact of climate change on agriculture could result in problems like food security and may threaten the livelihood on which much of the population depends.

The Impact

Climate change has had a significant impact on agricultural production. It is important to evaluate the vulnerability of agricultural production to climate change. The previous methods for evaluating vulnerability are inconsiderate and unrealistic. This paper proposes an improved vulnerability assessment method, introduces the Agricultural Production System Simulator (APSIM)-wheat model to evaluate vulnerability, and uses spring wheat, in Inner Mongolia, China, as an example for evaluating the vulnerability of spring wheat under climate change. The results show that, from 1996 to 2015, the adaptability to climate change of spring wheat production, in Inner Mongolia, increased, and its sensitivity to climate change decreased. That is to say, that climatic conditions have a negative impact on spring wheat, and adaptation measures have a positive impact on spring wheat. From 1996 to 2009, the vulnerability of spring wheat production in Inner Mongolia showed a very significant increasing trend, while showing a significant downward trend during 2009–2015, which is consistent with the actual situation. The improved vulnerability assessment method can reflect the actual impact of climatic conditions on agricultural production. We expect that the new vulnerability assessment method can provide a theoretical basis for studying the impact of climate change on agricultural production.

India is a large country with all types of climates and different kinds of soil requiring different types of farming. Most of the agricultural land in India is dependent on rainfall for irrigation. India has about 15 Agro-climatic zones with different types of farming methods and crops. As most of the population is dependent on agriculture and two-third of the country depend on monsoon rains to aid in agriculture, any change in frequency of the rains will affect these areas critically. Assessment of the effects of global climate changes on agriculture might help to properly anticipate and adapt farming to maximize agricultural production. At the same time agriculture has been shown significant effects on climate change, primarily through the production and release of greenhouse gases such as carbon dioxide, methane, and nitrous oxide. The impact of climate change on agriculture could result in problems like food security and may threaten the livelihood on which much of the population depends. Climate change can affect crop yields ( both positively and negatively), as well as the types of crop that can be grown in certain areas, by impacting agricultural inputs such as water for irrigation, amounts of solar radiation that affect plant growth, as well as prevalence of pests. The impact of climate change on wheat showed that its yield decreased due to the adverse effects of temperature during grain filling and maturity stages of the growth. The results of this study indicate that crop characteristics such as sensitivity of grain filling duration to temperature, play a major role in determining the effects of climate change on crop productivity. Several studies projected increase or decrease in yields of cereal crops, oilseed and pulses crops depending on interaction of temperature and CO2 changes in India. The present study has selected a thirteen years period from 2000 – 2012. .

Climate Change Adaptation Strategies

The impacts of climate change on marine capture fisheries have been observed in several studies. It is likely to have a substantial effect on fishers’ income and food security. This study aims to estimate the impact of adaptation strategies on fishers’ income and their household’s food security. Data were collected from small-scale fishers’ households, which own a fishing boat smaller or equal to five gross tonnages (GT). The study sites were the two coastal regions of Malang and Probolinggo in East Java, Indonesia, due to the meager socioeconomic resources caused by climate change. A probit regression model was used to determine the factors influencing the fishers’ adaptation. Propensity score matching (PSM) was applied to evaluate the impact of the adaptation strategies on income and food security. Food security was measured by food consumption score (FCS). The findings indicated that participation in the fishers’ group affected adaptation strategies significantly, and so did the access to credit and climate information. Also, PSM showed that the adaptation strategies had a positive and significant impact on fishers’ income and food security. Those who applied the adaptation strategies had a higher income and FCS than those who did not. This finding implies that the fishery sector’s adaptation strategies can have significant expansion outcome and reduce exposure to risks posed by climate change. Therefore, the arrangement of more climate change adaptation strategies should be promoted by the government for small-scale fishers in Indonesia.

The use of sewage sludge in agriculture decreases the pressure on landfills. In Romania, massive investments have been made in wastewater treatment stations, which have resulted in the accumulation of important quantities of sewage sludge. The presence of these sewage sludges coincides with large areas of degraded agricultural land. The aim of the present article is to identify the best technological combinations meant to solve these problems simultaneously. Adapting the quality and parameters of the sludge to the specificity of the land solves the possible compatibility problems, thus reducing the impact on the environment. The physico-chemical characteristics of the fermented sludge were monitored and optimal solutions for their treatment were suggested so as to allow that the sludge could be used in agriculture according to the characteristics of the soils. The content of heavy metals in the sewage sludge was closely monitored because the use of sewage sludge as a fertilizer does not allow for any increases in the concentrations of these in soils. The article identifies those agricultural areas which are suitable for the use of sludge, as well as ways of correcting some parameters (e.g., pH), which allow the improvement of soil quality and obtained higher agricultural production.
