Read the passage to review the vocabulary you have learned. Answer the questions that follow.
In countries like Niger and Mauritania, the cultivation of land has changed little in the past several centuries. Additionally, these countries’mono-modal rainfall pattern brings precipitation for only three months during the year. As a result, food production doesn’t nearly meet demand.
For this reason.”Several agencies and organizations have intensified their efforts to
increase the productivity of land in these countries.They have introduced new strains of seed, improved irrigation techniques, and introduced new methods of fertilization and soil management.With ample sunlight for photosynthesis and modern irrigation techniques, sustainable farming techniques should allow farmers to boost aggregate production in order to meet demand. Still, crop revitalization faces an unexpected adversary: institutional incompetence.Where crop specialists have convinced individual farmers to abandon old farming techniques in place of new, they can’t readily obtain the governmental cooperation they need.The biggest hurdles are political corruption, incompetence, and the absence of a marketing infrastructure.
