摘要

土地退化是影响全世界人类繁荣各个领域的一个普遍问题。本研究的目的是研究巴基斯坦开伯尔-普赫图赫瓦省马尔丹地区农户生计可持续性和土地退化。通过使用Slovin的“公式”,从总共857名注册农民中“随机”选择了90名农民。采用结构问卷面对面访谈法对农户进行初步资料收集,采用描述性统计和卡方检验进行分析。结果发现,由于LD的影响,农民的土地面积(44.44%)减少,但chi值不显著。据报道,作物产量也下降了42.22%。土地的耕作退化增加了土壤的可蚀性(24.44%),降低了土壤的产量(36.67%),并与农民的认知显著相关。过度放牧还会降低植被密度(16.67%),增加土壤压实和牛的践踏。土壤结构的变化也对农民的生计产生了影响,比如粮食产量下降,干旱的几率增加。盐碱化退化降低了土地生产力和收入,加剧了水资源短缺,影响了植物的营养生长,还导致降雨量减少,从而影响了农民生计的可持续性。结论是,粮食欠发达对农民未来的可持续性和粮食安全构成巨大威胁。该研究建议作出长期财政承诺,改善投资协调,同时允许家庭单位对其生计和计划生育做出正确的选择,通过促进家庭收入来源多样化,为其未来的生计可持续性和粮食安全减少对有限资源的压力。

Livelihood Sustainability and Land Degradation in Central Pakhtunkhwa of Pakistan
Land Degradation (LD) is a universal problem influencing all areas of human prosperity all over the world. The aim of this research is to study the farming household livelihoods sustainability and land degradation, in Mardan district of Khyber Pakhtunkhwa Pakistan. By using Slovin’s “formula”, 90 farmers were “randomly” selected through a total of 857 registered farmers. Primary data were collected through structure questionnaire face to face interview from the farming households (HH) and was analysed by using descriptive statistics and Chi-square test. It was found that as a result of the LD farmers land size (44.44%) was decreased but not significant as of the chi-value. Also decline in crop yield (42.22%) was reported. The tillage degradation of the land increased the eroadibility of soil (24.44%) and decreased its yield (36.67%) with a significant association of the perceptions of the farmers. The overgrazing has also affect on the LD by decreasing the plant density (16.67%), increased the soil compaction and trampling by cattle. The soil structure LD having also consequences for the farmer’s livelihoods like decreased the food production and increased the chances of droughts. Salinization degradation decreased the productivity of land, income and increased the water scarcity, affect the plant vegetative growth and also results low rain fall which alternatively affect the sustainability of the farmer’s livelihoods. It was concluded that LD is an enormous threat to the future sustainability and food security of the farmers. The study recommends for a long- term financial commitment and improved coordination of investments, coupled by allowing the family unit to make the right choices about their livelihoods and family planning to reduce the pressure on limited resources by fostering diversifications of income sources for the households for their future livelihoods sustainability and food security.
